Title: Yarn tension device
Inventor: FRIED BENJAMIN
IPC: D04B15/44
Filed: 1961-12-29
Abstract: 971, 344. Yarn tensioning devices for knitting machines and looms. MONSANTO CO. Dec. 29, 1961, No. 46709/61. Headings D1C and D1M. A control means for the tension of yarns passing from yarn packages to a yarn handling machine, such as a circular or warp knitting machine or a loom, comprises spring biased guide levers 2, each pivoted at 5 to a support 4 and having guide loops 3, and a control means comprising three concentric helical springs A, B, C, whose helices face alternately in opposite directions so that any yarn in contact therewith is forced into a zig-zag path as it travels through the springs. When a yarn comes off its package at the desired tension it pulls its guide lever 2 down as in Fig. 3 to avoid contact with the means A, B, C, but when yarn comes off at a lower tension the biasing spring 7 will raise the lever to permit the yarn to engage the helical springs as in Fig. 2. The anchorage point 8 is movable to vary the biasing effect of the spring 7. Breakage of a yarn passing through the guide loops 3 allows the lever 2 to move upwards to engage a contact element 10 to complete a circuit stopping the machine to which the yarns travel. When a yarn is not being used its lever 2 may be put out of action by flipping the spring 7 sideways past pivot 5 so that it pulls the lever downwards over-centre to rest against the helical springs, (Fig. 3a, not shown).

Abstract: 1,169,640. Optical tracking. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 18 Oct., 1967 [18 Oct., 1966], No. 47515/67. Heading H4D. Specification describes an optical tracking system, comprising optical viewing means 8 enabling initial visual acquisition of a target, optical projecting means L and photo-sensitive receiving means 1 establishing an electronic image of the target and its surroundings, scanning means 2x, 2y, scanning said electrical image along two (x, y) predetermined lines, defining at their intersection an " on track " position for the target image, to produce corresponding video signals, means Sx, 3y storing said video signals when an " on track " state is established, correlating means 4x, 4y comparing the instant video signals with those respective ones most recently stored to produce error signals representing the deviations of the target image from the " on track " position and servo control means 5y, 5x, receiving the error signals and repositioning the receiver 1 and projecting means L until said error signals are zero and an " on track " state is re-established. The receiving means 1 may be a vidicon television camera, and the optical viewing means 8 a television receiver. Means 8 is provided to enable initial " on track " video signals to be obtained for storage and comparison means. Each scanning means 2x, 2y may comprise a storage tube comprising full raster writing means 21x 21y and line scanning (mutually perpendicular) reading means 22x, 22y. The read-off video signals may be base and peak clipped to reduce interference and may be time quatized in quanta #. Each storage means may comprise two shift register arrangements 30x, 31x, 30y, 31y, one, e.g. 30x receiving the instant video signal and passing it to one side of the correlator 4x, and the other, e.g. 31x having its input connected to its output and so storing the last received video signal. Switches 32x, 32y are switched over on the detection of an " on track " state, such that the video signal circulating through means 31x is that corresponding to the most recent " on track " state and is read out in synchronism with the video signal from means 30x, to the other side of correlator 4x. Inertia means 6 may control the attitude of the system. The arrangement of Fig. 5 contains duplication of apparatus whereby simultaneous scanning in x and y directions is possible. Such duplication is not necessary with sequential scanning, Fig. 1 (not shown). Correlators 4x, 4y (Fig. 6A, not shown) contain a delay in one input whereby the output is on an unambiguous part of the triangular output characteristic (Fig. 6B, not shown).

Title: Brake valve assembly
IPC: B60T15/04
Filed: 1969-09-29
Abstract: 1,243,153. Valves. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. 29 Sept., 1969 [3 Oct., 1968], No. 47764/69. Heading F2F. A control valve for a fluid pressure braking system having normal and spring applied, fluid-released emergency brakes is operated in two stages, one for normal braking and the other for controlled emergency application of the spring applied brakes when fluid pressure in the normal braking circuit falls below a predetermined level. The valve has upper and lower sections 10, 14 controlling the supply of fluid to the normal brake chambers 32, 34 and emergency brake chamber 36 respectively by way of outlets 26, 78 and inlets 18, 58 connected to service and emergency reservoirs 22, 62. In normal operation when the driver depresses a pedal 42, a piston 38 is also depressed and valve seat 44 of a self-lapping valve engages a combined delivery and exhaust valve member 45 of a sleeve 48, a connection between a delivery cavity 24 and atmosphere through a bore 46 in the sleeve being interrupted. On further depression of piston 38, seat 44 forces sleeve 48 downwardly causing valve member 45 to disengage seat 50 thereby establishing connection between brake chambers 32, 34 and service reservoir 22 via conduit 20, inlet port 18 and cavity 24. Service reservoir 22 also communicates by a branch conduit 88 with the underside of a piston 90 biased upwardly by a spring 84, the fluid pressure which passes to release chamber 34 acting on the piston 90 upper face. In normal operation the downward force of a plunger 96, rigidly secured to piston 38, on piston 82 is not sufficient to overcome the combined force of spring 84 and the upwardly acting fluid pressure and the emergency brakes are held released by fluid pressure from reservoir 62 passing to chamber 36 via manual valve 60, conduit 58, chamber 56, chamber 76 and port 78. If fluid pressure in the reservoir 22 decreases below a predetermined value the downwardly acting plunger force on piston 82 causes the latter to move downwardly and an extension 80 thereof causes a valve member 68 of a further self-lapping valve and carried by a sleeve 71 to engage a seat 66 under the action of a spring 74 to disconnect reservoir 62 and chamber 36. Further movement of extension 80 disengages member 68 from a seat 92, fluid pressure in chamber 36 being partially vented to atmosphere by way of port 78, chamber 76, channel 64, sleeve bore 71 and port 54. The force of spring 64 temporarily overcomes the combined downward pressure of plunger 96 and chamber 34, pressure and member 68 engages seat 62. The process is repeated as the pedal is depressed. In a further embodiment plunger 96 engages a snap ring (100), Fig. 2 (not shown), carried by hollow extension 98 of piston 82, having Belleville washers acting between the piston and a section (97) of the extension engaging the plunger.

Abstract: 1,033,148. Hoppers; endless conveyers. AMERICAN CAN COMPANY. Dec. 21, 1962 [Jan. 2, 1962], No. 48354/62. Headings B8A and B8S. Bottle caps 1 (Fig. 1, not shown) in random orientation in a hopper 11 are gravity fed into the interior of a perforated drum 12 which is rotatably mounted in a surrounding outer casing 10. A blower 20 driven by a motor 50 sets up an air pressure differential so that air flows through an opening 56 in the casing 47 and into the interior of the drum 12 through the perforations 14 of the drum and out through the base of the casing 47 as indicated by arrows 60. The suction thus developed in the interior of the drum 12 causes the caps 1 to adhere to the inner periphery of the drum with the extremities of the flange of each cap pointing radially inwards of the drum. When the caps 1 reach the uppermost part of the travel of the drum they are engaged by endless belts 21, 22 (Fig. 4, not shown) by which they are conveyed to the exterior of the apparatus. The drum 12 is mounted on a ball bearing 83, 84, 85, at one end and engages a circular seal 92 at the other (Fig. 5, not shown). The drum may also be supported adjacent the lower part of the middle of its length by an assembly 89 of rollers (Fig. 2, not shown). Caps 1 being tumbled in the drum are prevented from falling out at the open end 56 by the presence of a baffle plate 98. Instead of atmospheric air being used for producing the suction effect a suitable gas may be used, e.g. nitrogen, and in this case a closed circuit arrangement is provided. Each cap 1 may have an arm 6 formed on it, the purpose of which is to engage a surface of the belt 21 so as to locate the cap into a desired orientation. A stop plate 124 prevents the caps 1 being carried by the drum 12 beyond the endless belts 21, 22. The position of the stop plate 124 may be adjusted by means of slots (not shown) engaged by screws 128 and if necessary by the interposition of shims (not shown). In addition to the plain form of cap 1 shown, a reversely dished form of cap having a central aperture, and suitable for aerosol containers, is described (Fig. 6, not shown).
