Patent GB-948519-A (GB)
Title: Improvements relating to arrangements for detecting signal transmission errors in telegraph and like systems
Inventor: COLLIS REGINALD EDWARD
IPC: H04L1/14
Filed: 1961-11-10
Abstract: 948,519. Telegraphy. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 25, 1962 [Nov. 10, 1961], No. 40355/61. Drawings to Specification. Heading H4P. The invention provides an error-detecting telegraph system in which the data sent is stored at the transmitter in a first store comprising a number of stages so that a corresponding number of character signals can be stored. The oldest signal stored is compared at the transmitter with the oldest character signal in a second store which receives signals from the remote receiver which are identical to the signals received by the receiver. Since the oldest character signal is not cleared from the first store until it has been compared with the corresponding signal in the second store no compensation has to be made for the propagation time: the first store must be capable of storing more signals than can be transmitted during the maximum propagation period likely to be encountered. In the embodiment described signals in 5-unit start-stop code are passed to the first store which can store up to six character signals. As each signal enters the store it is stepped along to the last vacant position in the store. When signals are received from the receiver they are similarly passed to the second store which can store only two character signals. The signals in the last position in both stores are compared and, if identical, are erased so that all the stored characters can be stepped along one position prior to the next comparison. If the signals are not identical an alarm is operated, no further character signals are fed to either store, and the stores are both cleared.

Title: Improved conveyor system
IPC: B65G17/06
Filed: 1969-08-12
Abstract: 1,269,346. Endless conveyers. J. S. BILDSOE. 12 Aug., 1969 [12 Aug., 1968], No. 40361/69. Heading B8A. A conveyer comprises a plurality of frame members 82; pivot 114 for pivotally connecting the frame members to one another in series; a plurality of load carrying pallets 12 each having a load carrying surface, a convex leading edge and a concave trailing edge, the pallets being secured to the frame members with their load carrying surfaces being closely adjacent one another to provide a substantially smooth and continuous overall load carrying surface for the entire length of the series of interconnected frame members 82; means for guiding and supporting the frame members and pallets for movement along a predetermined path; driven means supported by the frame members and including a vertically disposed frictional surface 170 disposed beneath the pallet load carrying surface and extending along the path; and powered driving means 210 frictionally engageable with the frictional surface to move the frame members 82 and pallets 12 along the predetermined path. The surface 170 may be flexible e.g. of rubber, or may be rigid e.g. if brake-lining material. It is formed by a series of separate elements 170 each secured to a respective frame member 82. The elements 170 are engaged by a series of drive assemblies 16. Each of these comprises an endless driving belt 210 which is driven by a motor 190 and is urged into engagement with the elements 170 by a group of three rollers 228 and associated rollers 242. These are loaded by springs 272. The pallets 12 are guided by the action of a wheel 116 mounted on each pivot 114 of the frame members 82, which is constrained by longitudinally-extending guide surfaces 66, 68. The pivot 114 also provides for a hinge joint between successive frame members 82. Each pallet may be of plywood or stainless steel, and has a non-slip load engaging surface of vinyl plastics, aluminium, or stainless steel. Each pallet is supported by castors 136 and 136, and by bolts 106, 106, which are carried by laterally extending arms 86, 88, of each frame member 82. In addition, a plate 150 (Figs. 3 and 4) is secured by screws 152, 152 (Fig. 3), to a forward upper surface of each member 82. This plate 150 engages in an arcuate channel 158 extending around the convex forward periphery of each pallet 12. In a modification (Figs. 6-9, not shown), intended for operating on inclined conveying paths, each pallet is formed of two portions hinged together about a transversely disposed horizontal axis. The pivotal joints between the frames 82 are arranged to have a degree of universal movement. The guide wheels 116 are peripherally grooved.

Title: Vehicle construction
Inventor: HULVERSON ADRIAN FRANCIS
IPC: B62D53/06
Filed: 1969-08-13
Abstract: 1282442 Adjusting axles longitudinally of vehicle FRUEHAUF CORP 13 Aug 1969 40402/69 Heading B7D A vehicle e.g. semi-trailer, in which the body is movable relative to the axle, includes a load-sensing device associated with the axle whereby such relative movement can occur, upon release of the body, until the axle is located at a predetermined load-bearing position relative to the body. The chassis frame has guides 35 (Fig. 4) for guiding channel members 34 supporting the body, and pins 39 which normally protrude through slots 71 in members 34 to lock the body to the frame. Upon raising a lever 44 the pins are retracted and a four-way valve 53 is simultaneously operated by movement of a link 48 by a pin 46 of the lever position 41. The four-way valve then supplies air to an air-chamber 61 and an elastomeric tube 38 on each side of the vehicle. The supply of air to the air-chamber 61 causes its plunger 59 to retain lever 44 in its operative position. Expansion of the elastomeric tubes 38 causes rollers 37 to be raised to engage the members 34 which can then be moved relative to the frame. Rearward movement of the body relative to the axle 14 (Fig. 2) causes a pressure increase in suspension air springs 24 which are connected to a pressure sensitive valve 65. The valve 65 is set to actuate when the pressure in the springs corresponds to the location of the axle at the predetermined position relative to the body, this location being determined in accordance with the maximum allowable axle loading. When valve 65 is actuated, it exhausts the airchamber 61 and the lever 44 returns to its normal position; at the same time the four-way valve 53 exhausts the tubes 38 to lower the body which is then locked to the frame by the pins 39. In another embodiment (not shown) the axle is suspended from a sub-frame which is movable relative to the main frame. In this instance the four-way valve additionally supplies air to the air brakes of wheels on the axle, and a one-way valve is provided to prevent exhaust of the normal brake-supply system during exhaust of the air-chamber and elastomeric tubes.

Title: Improvements in or relating to track circuits
IPC: B61L1/18
Filed: 1959-11-30
Abstract: 924,356. A.C. track circuits. WESTING- HOUSE AIR BRAKE CO. Nov. 30, 1959 [Dec. 3, 1958], No. 40544/59. Class 105. An A.C. track circuit without insulated joints, which may be made sufficiently short to detect the presence of each pair of rail vehicle wheels and may therefore be used to operate an axle counter, is defined by circuits 13 and 23 comprising, respectively, inductor 17 and condenser 15-and inductor 27 and condenser 25-which are adjusted to series resonance at the frequency of the applied signal. The signal is produced by a crystal-controlled transistor oscillator 43 (Fig. 3, not shown) operating at a frequency of e.g. 3.5 mc/s. and is applied across condenser 39 which, on one side, is connected as closely as possible to point 30 on one rail and, at the other side, is connected to the other rail at point 26 via a condenser 35 which forms a series tuned circuit with the inductance of the connecting lead 37. The condenser 39 and the inductance of the rails form a parallel circuit at the signal frequency which is tuned to resonance by the condenser. The resulting impedance between the rails at the signal frequency thus varies from a relatively high value at the mid-point of the circuit to a low value at its extremities. The presence of a vehicle axle within the circuit reduces the signal applied to a transistor receive element 51 (Fig. 4, not shown) from the series connected coils 21 and 31 which are coupled, respectively, to coils 17 and 27 of the end series tuned circuits, whereby a track relay 125 is released.
