Loop hole

“ This I overcame with my loop-setter invention. To explain briefly—
“As the full movement at the upper and lower reel is continuous, while at the aperture it is intermittent, a loop is necessary as a feeder for the take-up or the lower sprocket. If this loop is lost, the film becomes taut, the machine stops and the film may break. The loop-setter instantly readjusts this loop automatically, keeping it always in force.”
The taking of pictures is, of course, one of the interesting phases of the business from a popular standpoint. ”

“ Plate 10, Fig. 16 illustrates eyed patterns; here l and m are parts of decided loops; p, q, and r are decided whorls, but n is transitional, inclining towards a loop, and o is transitional, inclining towards a whorl. s is a nascent form of an invaded loop, and is nearly related to l; t and u are decidedly invaded loops.
The Arch-Loop-Whorl, or, more briefly, the A. L. W. system of classification, while in some degree artificial, is very serviceable for preliminary statistics, such as are needed to obtain a broad view of the distribution of the various patterns. ”

“ Imagine the process of constructing a tunnel, with all the efforts and time needed for cutting its passage through the resisting rock. When the tunnel is finished the activities necessary to its production are at an end. Whereas these continue for a limited time only, they leave behind them permanent traces in the existence of the tunnel, which one can describe dynamically as a definite alteration in the local conditions of the earth's gravity. ”

“ Yet, despite effort piled on effort and campaign mounted on campaign, over all the years, by engineers, politicians, and promoters, nobody has quite been able to push the project through. Up to now, every time the proponents of a tunnel have tried to advance the scheme, they have encountered a difficulty harder to understand, harder to identify, and, indeed, harder to break through than any rock stratum. ”

“ The gusts of air driven along the tunnel transformed the wide, old-fashioned keyhole into a sort of musical instrument; something in the formation of the lock must, I think, have lent itself to producing an unusually strange effect as the wind hummed and whistled through the hole. ”

“ A tunnel must be bored, for I forget how far, through virgin rock, with the help of inadequate tools and unskilled labour, and this tunnel must be finished by a certain date. A hundred unexpected difficulties arose, and one by one were conquered. Great dangers must be run, and were avoided, while the responsibility of this tremendous engineering feat lay upon the shoulders of a single individual, Oliver Orme, who, although he had been educated as an engineer, had no great practical experience of such enterprises. ”

“ The danger of the Tunnel would be an increasing one, because, as time went on, the precautions would be neglected. Why should a new danger be added to those which already existed? From the commercial aspect, even a shadow of danger would be a heavy balance against any possible advantages. The liabilities to panics would be increased," He says in conclusion:—"We hear much of the panic-monger in the writings of those who favour the construction of this Tunnel. ”

“ This will cause electromotive forces in opposite directions to be generated in these portions of the loop, and these will tend to aid each other in causing a current to circulate in the loop in the direction shown by the arrows associated with the dotted representation of the loop. It is evident that as the motion of the loop progresses, the rate of cutting the lines of force will increase and will be a maximum when the loop reaches a horizontal position, or at that time the two portions of the loop that are parallel with the axis will be traveling at right angles to the lines of force. ”

“ Today a thought is born and tomorrow it is a giant, parting seas and moving mountains. The waste of yesterday is turned into the raw material of new manufacture, with its million wheels moving faster and faster. But back of it all, inevitably and eternally, is a busy human brain and unsatisfied energy.
Wire rope had lingered, waiting for civilization’s loads to grow. ”

“ And notwithstanding the heavy responsibility which rests upon me, from all which you gentlemen of science are, happily for yourselves, so free, I feel that as regards the works of the Box Tunnel everything necessary has been done to render them secure, and that the doubts and fears you have so easily raised, but which it might be more difficult again to set at rest, are entirely unfounded. ”

“ The old board never did, for that matter; but, thanks perhaps to younger blood, they've begun now to build as they should have built in the first place. It isn't finished yet, that double-looped tunnel, it won't be for years, but, no matter, it's begun, and some day a good many more than a few men will sleep the easier because of it. ”

“ Clang, clang, clang, we passed right under the thumping levers of another vast machine, and so came at last to a wide tunnel, in which we could even hear the pad, pad, of our shoeless feet, and which, save for the trickling thread of blue to the right of us, was quite unlit. The shadows made gigantic travesties of our shapes and those of the Selenites on the irregular wall and roof of the tunnel. Ever and again crystals in the walls of the tunnel scintillated like gems, ever and again the tunnel expanded into a stalactitic cavern, or gave off branches that vanished into darkness. ”

“ A problem which arises in many programming languages is that loop control variables are global to the iterative control and thus will have a value after loop termination but that value is usually an accident of the implementation. Specifying the meaning of control variables after loop termination in the language definition resolves the ambiguity but must be an arbitrary decision which will not aid program clarity or correctness, and will interfere with the generation of efficient object code. ”

“ Since similar conditions prevail with respect to A B, for its corresponding movement, it is evident that the number of lines which thread through the loop are decreased with increasing rapidity as the loop rotates through the first quarter of a revolution, and increased with decreasing rapidity during the second quarter of the revolution. ”

“ The fall of earth did not extend many yards, and beyond it we found ourselves in the continuation of the tunnel. On, on, on we went, moving slowly, with only the uncertain light of the tiny lamp to warn us of any dangerous pitfall which might lie in our path. Contrary to my expectation, we encountered no further obstacle of a similar kind to that through which we had just cut our way. Now we were passing once more through solid rock, and now the tunnel was continued through earth, supported by rough-hewn beams, black with damp and age. ”

“ You could abandon the ‘A’ end and complete the tunnel by working the ‘C’ end only, of course, but you are not able to work enough men on one end to complete the job on time and as per contract. You must have two gangs working toward each other. But a slide occurs at ‘B’ which you cannot stop. It strikes me that the rock roof is thinner at ‘B’ than you found it while working toward ‘B,’ or else the slide would have occurred before it did. ”

“ A common iterative construct is the DO loop. The most general form we have seen in any programming language is the MacLISP DO [Moon] . It permits the simultaneous initialization of any number of control variables and the simultaneous stepping of these variables by arbitrary functions at each iteration step. The loop is terminated by an arbitrary predicate, and an arbitrary value may be returned. The DO loop may have a body, a series of expressions executed for effect on each iteration. ”

“ EDGE—With right side of work toward you, join thread in 10 ch loop at corner, 6 s c, ch 4, 6 s c in same loop, 2 s c in each of the next 2 loops, 6 s c, ch 4, 6 s c in next loop, s c in 3 ch loop, ch 3, s c in same loop, 6 s c, ch 4, 6 s c in next loop, 2 s c in each of the next 2 loops, 4 s c in each of the next 2 loops, 2 s c in each of the next 2 loops, 6 s c, ch 4, 6 s c in next loop, s c in next 3 ch loop, ch 3, s c in same loop, 6 s c, ch 4, 6 s c in next loop, 2 s c in each of the next 2 loops, continue all around in same manner, break thread. ”

“ It's too expensive—uses up force for nothing. You don't want any ground-connection except the one through the negative brush. The other end of every wire must be brought back into the cave and fastened independently, and without any ground-connection. ”

“ Furious with rage, he caught up a small hand-spike [12] that lay near, and poised it in his hand with the intention of throwing it at his tormentor. Loop saw what he was about to do, and immediately, as rapidly as possible, moved from his position, and kept changing from place to place, with a quickness that baffled the fat cook’s aim; but when he had ascended to a greater height, and was passing from one point to another with a velocity that seemed impossible to be imitated, his foot slipped, and with a scream that made all on deck aware of his danger, he fell headlong into the sea. ”

“ These inconsistencies can cause circular routes (called routing loops) where once a packet enters it is routed in a closed path until its time to live (TTL) field expires and it is discarded.
Other algorithms may know about only a subset of the network. To prevent loops in these protocols, they are usually used in a hierarchical network. They know completely about their own area, but to leave that area they go to one particular place (the default gateway) . Typically these are used in smaller networks (campus, regional...) ”

“ If worst came to worst, we could resort to rock chipping—and, of course, it would be possible, even in case of really lost direction, to work up to full daylight by one channel or another if granted sufficient time for plentiful trial and error. So, at last, we set off eagerly in the indicated direction of the nearest tunnel.
According to the carvings from which we had made our map, the desired tunnel mouth could not be much more than a quarter of a mile from where we stood; the intervening space showing solid-looking buildings quite likely to be penetrable still at a subglacial level. ”

“ There would be nothing left to do but to grope hungry through dark streets and, if you could find a wireless bridge, go back to Lonelyhurst, where you would learn that without wire there is no domestic joy in this earthly tabernacle, for from cellar to roof, from the bale and rim of the coal-scuttle and the binding of the broom, from the cooking pots, the dishpan and all other culinary utensils to the baby’s toys and mother’s corset and hairpins and needles and safety pins and pins, it is all wire one way or another. ”

“ It is not a tunnel in general which he has to make, but a tunnel having its own special end and called for by its own set of circumstances — a set of circumstances not capable of being precisely duplicated anywhere else in the world. ”

“ I was never disposed to give a guarantee to the extent of one single farthing to the promoters of this scheme, or any other scheme of a similar kind. I find it necessary, for my own credit, perhaps, at any rate for the truth of history, to disclaim it. Sir, I was instructed on behalf of the Government, and with my own full concurrence, to refuse a guarantee; but we did so without giving the slightest opposition to the Tunnel scheme. A series of other Governments followed, and every one of those governments officially committed itself on the merits of the Tunnel. ”

“ It also appears in every metallic loop, and vitiates the measurements of electromagnetic inertia and of capacity of loops. Thus, if we measure the capacity of a loop as compared with a single wire, the amount per mile may be 50 per cent. greater than it ought to be; while if we measure the capacity of one branch of a circuit under the conditions of the London-Paris telephone line, it may be 50 per cent. less than it ought to be. This effect of M is shown by the dotted line in Fig. ”

“ Of course, the tunnel is fitted with air locks by which men can enter the working section without permitting the compressed air therein to escape, and these locks are just like those used in sinking a caisson, except that they are horizontal instead of vertical. ”

“ In fact, the traffic has now become so large that it is more than we can handle, particularly the goods and coal traffic, and we are at the present moment making arrangements for putting the block system in the Tunnel itself, so as to divide it into lengths. ”

“ Feedback mechanisms are a very common way for natural systems to regulate their own behavior. Dynamically complex systems, with their layers of interlocking constraints, have ample opportunity to develop a tangled thicket of feedback loops. Jay Forrester, in his 1969 textbook on the prospects for developing computational models of city growth, writes that “a complex system is not a simple feedback loop where one system state dominates the behavior. ”

“ Work as for 1st block to 14th rnd incl. 15th rnd: Make 1st 9 loops as on 1st block, ch 2, sl st in corresponding loop on previous block (always be sure to keep blocks right side up) , ch 2, sc in next loop on block in work, ch 2, sl st in next corresponding loop on 1st block, ch 2, sc in next loop on block in work (2 ch-5 loops joined) . Ch 2 and continue thus until 7 joined loops are made, ch 2, cluster over next 3 dc, * ch 2, sl st in ch-5 between next 2 clusters on 1st block, ch 2, cluster over next 3 dc on block in work. ”

“ WIRE HOLDS THE WORLD TOGETHER It is wire that has brought the world together and holds it together, and when the wire mills stop, as even they would have to do if there were no wire, modern civilization might as well be dead, and it would be. ”
