Tape measure

“ These spring up almost as if by magic. To measure the growth from day to day no expensive auxanometer is needed, but only a tape measure and a coolie to climb an adjacent tree with the end of the tape. ”

“ As he spoke, he whipped a tape measure and a large round magnifying glass from his pocket. With these two implements he trotted noiselessly about the room, sometimes stopping, occasionally kneeling, and once lying flat upon his face. So engrossed was he with his occupation that he appeared to have forgotten our presence, for he chattered away to himself under his breath the whole time, keeping up a running fire of exclamations, groans, whistles, and little cries suggestive of encouragement and of hope. ”

“ A good map is impossible if the board twists.
To measure the distance between [3] stations, a 50 or 100-ft. tape, or some accurate substitute, is necessary. An ordinary piece of iron telegraph wire, 105 ft. long, is a good substitute. A point, about 2-1/2 ft. from one end, is marked with a little lump of solder. A chisel dent in this solder will mark one end of the 100-ft. section. Then, with a borrowed tape or a good rule, measure off and mark every 10 ft., just as the first point was marked, until the entire 100 ft. have been laid off. The last 10 ft. should be divided into feet. ”

“ Elsewhere it is explained why a narrow tape will record a shorter measure around the fleshy parts of a person than a broad strip of cloth, say ten inches wide. It should also be observed that a broad strip of material, drawn around the seat while standing, will record, say about one and one-half inches more than a narrow tape half an inch wide, both being drawn with the same strain. When a person is sitting, the length of the abdomen contracts, but increases in circumference, and may expand anywhere from one inch, in a person of light build, to five inches in one that is quite fleshy. ”

“ The third or middle compartment between the spool case and darning thread can be used for a miscellaneous pocket to hold the tape-measure, emery-bag, small scissors and other necessary articles.
Fig. 57. The flannel sheets tacked through the centre
A piece of tape stretched down on the denim with just enough spring for the package of needles to pass through is a handy way to carry them (Figure 58) .
It is rather dangerous to travel with a pair of scissors with the points unprotected. In Canada [49] and the states that border it the Indians sell the little sweet grass protectors. ”

“ When they are returned, he threads them one after another upon the tapes, holding the latter in a loop, so that the balls may sink down to the middle, and so cover the point of junction. He next requests two of the company to come forward and hold the tapes, and hands two ends to the one and two to the other. Each person believes that he holds one end of each tape, though, in reality, each has both ends of the same tape. The performer now takes from each one of the ends which he holds, and crossing the tapes in the manner shown in Fig. ”

“ A measuring tape may be made by taking a narrow white tape, say 1⁄4in., and winding it on a slip of card barely an inch wide, just so little spirally that each turn may not half cover the preceding one, then carefully blacken the edges, and, when you unwind the tape, mark every twelfth inch with figures to denote feet, and every sixth with an extra line. ”

“ It is desirable to tie the portfolio together on one side at least. For this purpose secure tape of harmonizing color and 3⁄8 or 1⁄2 inch in width. About 1⁄2 an inch from and parallel to the front edges cut a slit through both paper and newsboard of the same length as the width of the tape. (This needs to be done with a knife or, better yet, with a chisel.) Insert a piece of tape from 6 to 9 inches long in each slit and securely paste at least 1 inch to the inside of the newsboard, allowing the greater length to project from the outside. ”

“ This and any diagram in the book may be reproduced by using a graduated tape to agree with the breast measures and applying the units in the same way as the inches are for the full size; if of the old make using a tape a size larger for the small sizes and a size smaller for the very large ones, say a 12+1⁄2 tape for a 24, and a 21+1⁄2, for a 44 and so on: or they may be drawn out by the scale given previously by merely using the ordinary inch tape in the manner described. ”

“ Six metal fingers sense the holes in the paper tape and give out electrical impulses at proper times. At the front of the problem position is a small group of switches that provide complete control over the problem while it is on the machine. These are switches for starting, disconnecting, momentary stop, etc.
One tape transmitter is the problem tape transmitter. It takes in all the data for the problem such as the starting numbers. The first thing it does at the start of a problem is to check (by comparing tape numbers) that the right tapes are in the right feeds. ”

“ The Bain apparatus was in actual operation in the younger days of the telegraph. Various systems, based on similar principles, involving tape transmission and the production of dots and dashes on a receiving tape, have from time to time been devised, but have generally not succeeded in establishing any permanent usefulness in competition with more effective instrumentalities which have been perfected. ”

“ In no instance should a transparent lift ever be folded back on itself or stuck to another piece of such tape as a backing, since it is generally not possible to determine the correct position of such a print. ”

“ The first record was made at the time of the observations by dots or punctures made in a tape running over a drum, the spaces between the dots representing corresponding lengths of time. The tape was prepared for use by being marked off by printed dots, about a third of an inch apart, into spaces representing seconds. The permanent record was prepared subsequently by reading off the results noted upon the tape. To read off the whole seconds was of course a simple matter of enumeration of spaces representing seconds. ”

“ Never turn the hands backward; indeed, it is best not to set them to any given place, but to note the number they stand at when you begin to walk. The adjusting the tape to its exact length is a critical business, and will cost you many trials. ”

“ Shortly after the invention of telegraphy, operators learned that they could read the message by the click of the marker against a metal rod which took the place of the tape. In practically all telegraph offices of the present day the old-fashioned tape is replaced by the sounder, shown in Figure 219. When current flows, a lever, L, is drawn down by the electromagnet and strikes against a solid metal piece with a click; when the current is broken, the lever springs upward, strikes another metal piece and makes a different click. ”

“ A certain group of perforations corresponds to a Morse group of dots and dashes for a letter of the alphabet. When the tape thus made ready is run rapidly through a transmitting machine, electrical contact occurs wherever there is a perforation, permitting the current from the battery to flow into the line and thus transmit signals correspondingly. At the distant end these signals are received sometimes on an ink-writing recorder as dots and dashes, or even as typewriting letters ”

“ The parity flag is set if the parity condition is not met while the tape is being read (during MWA, MWB, MRA, or MRB) .
The end of tape flag is set when the tape comes to the end of tape, moving in either direction.
Three conditions set the read-write check flag: 1) If TC is inactive, i.e., no unit or function selected, and an MPS instruction is given. The MPS becomes a no-operation, no-halt instruction. 2) When reading information and not emptying the TC buffer, by giving an MPS before more information arrives from tape. 3) A unit becomes unavailable during a normal sequence. ”

“ The zero mark of the tape being placed against a mark on the rail which serves as the starting-point, a second mark is made on the rail opposite the hundred-foot mark of the tape. The tape is then placed in position a second time with one end on the second mark, and a third mark is placed at the farther end ”

“ The Phonograph cylinder E, was rotated while words and sounds were shouted to the support to which the water jet was attached, and a record that was quite visible to the unaided eye was the result.
The tape recorder, an unusual instrument which recorded mechanically on a 3⁄16-inch strip of wax-covered paper, is one of the machines described and illustrated in U. S. patent 341214, dated May 4, 1886 (see fig. 4) . ”

“ The method of packing reams or parcels is sometimes excellent, but at other times it leaves something to be desired. If the wrappers are not strong enough for the paper contained, they break as the reams are moved, and the edges of the paper are likely to become damaged. Fastening is done with paper tape, webbing, or string, according to the size and weight of the parcels. Light and small sued paper may be fastened with paper tape, all sizes and weights with webbing or cotton tape, and heavy papers with string. ”

“ Using both upper and lower pieces of transparent tape creates a cavity for mounting wet specimens such as live algae suspended in water. Since the paper microscope slide is less than half the thickness of a standard glass slide, a spacer is required to elevate the sample closer to the lens. ”

“ When corset is properly laced and adjusted place the tape with buckle around waist, usually at point of least circumference, so that the lower edge of the tape is exactly upon waist line, draw tightly and fasten to hold stationary while all longitudinal measurements are taken. ”

“ Tape, tāp, n. a narrow fillet or band of woven work, used for strings, &c.: a strong flexible band rotating on pulleys for directing the sheets in a printing-machine: the strip of paper used in a printing-telegraph instrument, &c.: (slang) liquor.—v.t. to furnish, or tie up, with tape: to extend.—ns. Tape′-line, -meas′ure, a measuring-line of tape, marked with inches, &c.—adj. Tā′pen, made of tape.—n. Tā′pist, one who uses tape, an official formalist.—Breast the tape, in foot-racing, to touch with the breast the tape or ribbon held by the judge at the finish-line. ”

“ Two hundred characters, each having 6 bits plus a parity bit, are written on each inch of tape and the tape moves at 75 inches/sec. The tape control has the job of connecting a specific unit to the PDP-3 and is a switch. It also has the function of controlling the format of information that is read or written on tape. In-out class commands instruct TC to the type of information transfer and select the tape unit. Another IOT command synchronizes the transfer of information through the TC to the computer. ”

“ Then put these two pieces together as represented in Figure 2, having previously slipped between them a piece of common tape, also represented in the diagram (the tape must be just the same width as the [Pg 39] wood) ; then wind some thread round the whole thing lengthwise (to keep the bits of wood together and the tape taut) , and the Punch-trumpet is made, as represented in figure 3. Place the instrument between your lips and blow; if you cannot produce noise enough to distract any well-regulated family in three-quarters of an hour, we are very much mistaken. ”

“ The press-lever is actuated by the press-magnet. From the diagram it will be seen that the armature of the latter has a long, pivoted extension arm, or platen, trough-like in shape, in which the paper tape runs. It has already been noted that the object of the press-lever is to press this tape against that character of the type-wheel centrally located above it at the moment. ”

“ This gives the value of a turn—
Note.—The micrometer has been sent to Professor Mayer, of Hoboken, to test the screw again, and to find its value. The steel tape has been sent to Professor Rogers, of Cambridge, to find its length again. (See page 145.)
Measurement of the Distance between the Mirrors.
Square lead weights were placed along the line, and measurements taken from the forward side of one to forward side of the next. The tape rested on the ground (which was very nearly level) , and was stretched by a constant force of 10 pounds. ”

“ Besides the 500-ft. steel tape, which was graduated to single feet, except at each end, where 1 foot was graduated to tenths, a 100-foot steel tape graduated throughout to feet, tenths, and hundreths was used for shorter measurements. ”

“ Perforating Murray system. machines equipped with typewriter keyboards are used for the preparation of the messages, two or three keyboard perforators being employed at each end of the telegraph lines on which the Murray system is used. The messages in the form of perforated tape are then passed through an automatic transmitter, something like a Wheatstone transmitter, at a speed of about 100 words a minute. At the receiving station electrical mechanisms record the signals once more as perforations in a paper strip forming an exact replica of the transmitting tape. ”

“ Increased rapidity of transmission may, however, be accomplished by automatic methods, by means of which, through the employment of suitable devices, messages may be stamped in or upon a paper tape, transmitted through automatically acting instruments, and be received at distant points in visible characters, upon a similar tape, at a rate twenty or more times greater—a speed far beyond the possibilities of the human hand to transmit or the ear to receive. ”

“ They provide a simple way to apply arrows, lettering etc. and to reinstate short lengths of line without the need for substantial application and support equipment.
23.6 Preformed cold plastic material is applied to the road surface using an adhesive.
23.7 Preformed tape is produced in sheet or roll form and is either bonded to the road surface or inlaid. Pressure is applied, but not heat. Preformed markings have good durability, are of uniform thickness and do not spread in hot weather or under the weight of heavy traffic. ”
