Title: Folding apparatus for sheets and like flat work
IPC: D06F89/00
Filed: 1962-01-16
Abstract: 947,435. Folding sheets &c. CHICAGO DRYER CO. Jan. 16, 1962 [Jan. 31, 1961], No. 1515/62. Heading D1S. Folding apparatus for sheets &c. comprises a number of conveyers 24, 26, 28 which are at least in part superimposed over each other and each of which moves in the opposite direction to the successive conveyer and folding means associated with the conveyers to fold the conveyed articles, the article receiving end of each conveyer being situated beneath an overlying conveyer so that a conveyed article engages both conveyers in the course of transfer therebetween and each lower conveyer travelling at a greater speed than the immediately overlying conveyer. The conveyers 24, 26, 28 comprise a number of tapes passing around rollers 20, 20a. Sprockets 46, 48, 50 fixed to the rollers 20a are driven by a motor 36 and are of diminishing size so that the conveyer 26 moves faster than the conveyer 28 which moves faster than the conveyer 24. A sheet S is fed from the discharge conveyer 30 of an ironer on to the conveyer 24 with its selvedges lying along the length thereof. The leading edge L of the sheet S deflects an arm 54, Fig. 3, to close a switch 56 which does not actuate any apparatus until the sheet S has proceeded up inclined fingers 60 secured to a bar 62 and the edge L has deflected an arm 64 to close a switch 66. A coil in a four-way solenoid valve 70 (not shown) is energized to actuate a spring-biased valve therewithin to supply compressed air to the lower portions of cylinders 74, 76, Fig. 4. The piston rod 78 of the cylinder 74 moves upwardly so that, through the linkage shown, a clamping rod 90 pivots downwardly to clamp a forward portion of the sheet S against a fixed plate 57 slotted at 59 to allow movement of the arm 64. Upward movement of the piston rod 98 of the cylinder 76 causes the bar 62 to pivot to retract the fingers 60 to the position shown in Fig. 4. The portion of the sheet S contiguous with the clamped portion is carried on by the conveyer 24 and when the trailing edge T thereof disengages the arm 54 to break the circuit energizing the valve 70 so that the rod 90 is instantaneously released to allow the edge L to drop on to the edge T. A control device 116, Fig. 6 (not shown), is provided to control the rate of escape of air from the cylinder 76 so that the fingers 60 slowly return to their inclined position. The positions of switches 56, 66 are adjustable by turn-buckles 120. The half-folded sheet S passes on to the conveyer 28 which is inclined to the horizontal at an angle of less than 15 degrees and is quarter-folded by similar folding elements with the folded bight portion dropped beyond the edges L, T, see Fig. 1. The sheet S passes on to the conveyer 26, is delivered on to a platform 34, and is folded manually about fold lines F, Fig. 7, with the edges L, T inside. By deactivating the folding elements work may pass through the machine with no folding taking place. Examples of the relative speeds of the conveyers 24, 26, 28, 30 are given.

Abstract: 543,757. Angular bending; drawing. REYNOLD'S TUBE CO., Ltd., and MOLE, F. W. Feb. 5, 1941, No. 1518. [Class 83 (iv)] The angle of the flanges of angles, channels or like bars, particularly for forming spars for aircraft wings, is altered by a tool consisting of an arm-like member d which at one end receives and bears against the opposite faces of the flange and at the other end is pivoted on a support c. The support may be traversed longitudinally on the bed or table a or vice versa, by power driven screw and nut, rack and pinion or chain and sprocket gear, the member d being mounted so that it can swing freely in a transverse plane. The forked end of the member may be provided with anti-friction rolls e. The work b is secured by a clamp h on the table at an inclination to the line of motion so that as the support c is traversed the angle between the flanges is gradually reduced or increased. To vary the amount of bending at different portions of the length the work may be sprung out of its straight condition to a curved form when being secured on the table, or the pivot of the member d may be carried by a hand or automatically adjusted slide on the support c.

Title: Method and device for tying thread ends
IPC: B65H69/04
Filed: 1965-01-14
Abstract: The usual knot tying apparatus for tying a weaver's knot is modified to enable a weaver's knot to be tied when the yarns are presented to the apparatus from opposite directions.  To this end first one yarn F1 is presented to the beak of the apparatus and the beak is manipulated by turning it through 180 degrees and back again to cause a loop to be formed in the yarn, Fig. 5 (not shown).  The second yarn F2 is then presented to the outside of the beak, Fig. 6 (not shown) and the beak is then twisted through 360 degrees to twist the second yarn about the first and to engage the second yarn in its beak, Fig. 9 (not shown.)  The two yarns are then lifted off the beak to complete the weaver's knot Fig. 11 (not shown).  The apparatus for performing the knot tying operation is provided with double portion spiral 15 on the shank of the beak 1, Fig. 12 (not shown) which is manipulated by the slotted rod 14, cam actuated to impart the desired twisting motions to the beak.  The usual sinkers 4 present the yarns F1, F2 in turn to the beak after they have been extended in slots over the plates 2.

Title: Controlling the speed of a vehicle travelling along a pathway
IPC: B61L3/00
Filed: 1973-01-17
Abstract: 1417754 Train control SIEMENS AG 17 Jan 1973 [21 Jan 1972] 2534/73 Heading B7N A train is controlled to a required speed (which can be zero) at a signal location by developing a braking curve on the train which is effectively positioned relative to the track in dependence on the required speed. The curve is derived from the relationship (Vs)<SP>2</SP>=2bs where Vs, b and s are speed, acceleration and distance respectively. Assuming a train has to be brought to a standstill at a signal location the train receives at a position in advance of the signal an indication of the required speed Vz at the signal and a measure of the distance between the position and the signal location. The received indication is stored in unit 1 and its reception restores a distance counter W (providing the value s) and a store Sp to zero. Unit 2 which computes the braking curve Vs from the value s and a fixed value of deceleration b set in unit 3 thus initially issues a value Vs=O which is compared with the required speed Vz=O in comparator K1. The comparator provides an output signal to open gate SG1 to feed the signalled distance into the counter W. The braking curve Vs is then generated by the unit 2 as tachogenerator 5 provides distance travelled pulses to count down the distance value s stored in the counter. This value of Vs is applied with a signal Vi derived in unit 4 from the tachogenerator 5 to a normal braking system (not shown) and also to a comparator KL which supplies an emergency braking signal to switching unit BS if Vi exceeds Vs. If the required speed Vz is not to be zero at the signal the comparison of the required speed Vz and the initial zero-value of Vs now provides an output from comparator Kl which closes gate SG1 and simultaneously opens gate U2 which actuates a pulse generator T which feeds pulses to the counter until the resultant value of s applied to computer 2 produces a speed value Vs equal to that Vz required at the signal. When equality occurs the pulse generator is blocked and gate SG1 is again opened to add the signalled value of distance to that already entered in the counter. The computer now provides a braking curve which is effectively moved along the track and which when followed brings the train to the required speed at the signal.

Abstract: 939,233. Selective printing. POSTMASTER GENERAL. Jan. 19, 1960 [Jan. 23, 1959], No. 2626/59. Class 100 (4). [Also in Groups XIX and XXX] A printing machine for marking codes on letters 1 in a letter-sorting apparatus comprises helices 29 for feeding the letters one-by-one to a coding position B having fourteen hammer rods 12 selectively operated by a keyboard K to transfer a phosphorescent substance carried on a transfer ribbon 19 on to the letter 1. The town destination code, e.g. the first three and last two letters, is translated at T into a binary code and entered in a data store S, from where it is read out to operate certain electromagnets 13. The armatures cause levers 14 to engage the appropriate hammer rods 12 which pass through an aperture 6 in a face-plate 5 and the phosphorescent substance described in Specification 870,504 is transferred. After marking the letters pass in front of a low-pressure ultraviolet source 23 so that the marks are activated and the letter is then passed in front of a slit 24 in the tube of a photo-multiplier housing 25. The code thereby read is compared at 37 with the data stored and if the two are identical the letter is allowed to proceed to the sorting apparatus. The hammer rods are heated by electrical elements in the block 15 controlled by a thermostat. In a modification the hammer rods are mounted in a housing which swings all the hammer rods into contact with the transfer ribbon but only those which are to effect transfer are heated. The hammer mounting blocks are resiliently mounted to accommodate varying letter thicknesses. Specifications 656,873 and 768,504 also are referred to.
