Title: Load retaining devices
IPC: B66C1/34
Filed: 1971-10-18
Abstract: 1406426 Hooks SPERRY RAND Ltd 3 Oct 1972 [18 Oct 1971] 48378/71 Heading E2A [Also in Division B8] A load bearing device comprises a pair of jaws 1, 2 pivotally mounted between plates 3, 4 the jaws being movable linearly when closed in a direction in which a load held by the jaws acts thereon and means for securing the jaws against relative pivotal movement when so displaced. As shown in Fig. 9, the jaws 1, 2 have keyhole slots with part cylindrical sleeves 18, 24 extending therefrom and are joined by a shaft 9 with opposed flats 14 and with cylindrical end portions 10. The shaft 9 fits within the sleeve 18 upon which turns the sleeve 24 and the end portions 10 project beyond the jaws rotatably into holes in bushes of the plates 3, 4, the shaft being non-rotatably engaged in the narrower portions of the keyhole slots when a load is applied to the jaws and the jaws have consequently been displaced downwardly. The jaws are released by relieving the load from the jaws, springs 29 then raise the jaws until the shaft 9 reengages the sleeves and the jaws are pivoted to the open position by a Bowden cable 33. The jaws are held open by an end portion 40 of a pawl 36 pivoted to the jaw 1 engaging in a notch 41 in the sleeve 24 of the jaw 2. The load on entering the space between the jaws strikes the pawl which disengages the notch 41 to allow the jaws to close under the action of the springs 29. To control or monitor the device a microswitch 43 is operated by a plunger just proud of a tip when the jaws close, microswitches 47, 48 on the plates 3, 4 are operated by the jaws to indicate when fully open, a microswitch on the jaw 2 has a leaf 50 which when depressed by the load indicates when the jaws are loaded. The devices may be used to prevent damage to a linear induction motor of a vehicle in an emergency. The stator of the motor has two spaced transverse bars which are grasped by two pairs of the devices on the vehicle when, in an emergency, a hydraulic system retaining the stator on the vehicle raises the stator. When the hydraulic system is subsequently cut out the devices lock the bars and the vehicle can be brought to rest without damage to the stator.

Title: Improvements in or relating to data processing systems
IPC: G06F7/495
Filed: 1964-11-30
Abstract: 1,049,689. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1964 [Dec. 31, 1963], No. 48518/64. Heading G4A. In a data processing system comprising a table look-up memory (e.g. read-only) each location of which stores the result of an arithmetic operation on two operands, the memory is addressed by logical combinations of said operands. This enables the number of memory locations storing identical results to be reduced. The logical operations may be ANDing together corresponding bits of the two operands A, B and EXCLUSIVE-ORing (or NORing or ORing) together corresponding bits of the two operands. Alternatively A together with A EXCLUSIVE- OR B may be used for addressing the memory. If the stored table is an addition table, some locations will have a carry indicator ( ! ), but as a modification the carry indication may be obtained from the circuitry performing the logical operations, thus enabling the results n and n! to be stored as n in one location in the memory. The addressing signals obtained from the operands are in addition to a base address depending on the arithmetic operation required. Conversion from BCD to pure binary and back again may be provided before and after the performance of the logical operations, respectively. It is shown how the invention may be incorporated into the system of Specification 938,188 which is referred to and has provisions for addition, subtraction and multiplication by table look-up.

Title: Method and apparatus for the impregnation of wood or other permeable material with a preservative solution
IPC: B27K3/10
Filed: 1971-10-22
Abstract: 1374277 Impregnating wood &c BOLIDEN AB 22 Oct 1971 [22 Oct 1970] 49258/71 Heading D1P In the impregnation of wood &c by the alternating high and low pressure technique, the pressure may be varied in a controlled manner during the low pressure phases by drawing preservative solution into and through the vessel under controlled flow conditions during the low pressure phases. The low pressure may be varied between successive phases or during a single phase. As shown, a treatment vessel 10 is in permanent communication with a switch manometer 28 and connects via a valve 31 with a switch vacuometer 30. The, vessel 10 is connected by three lines 12, 21 and 15 with a storage tank 11 for preservative solution. During a low pressure phase, suction is applied along lines 21, 15 to draw solution out of the vessel. The vacuum existing in the tank causes solution to be drawn from the storage tank along the line 12 having a non return valve 14 and into the vessel 10, thus creating a circulation. The flow along the line 12, and hence the pressure in the vessel 10 is controlled by the reading on the vacuometer 30 which gives rise to signals along lines L2, L3 to control the servo motor regulating the valve 13. The flow rate is controlled to maintain the vacuometer reading between predetermined limits A, B. The limiting readings may be preset manually by a control C, or may be programme controlled e.g. by a camming arrangement. The servo motor 32 may be an electric motor. The signals from the vacuometer may alternatively be hydraulic or pneumatic. The vacuometer is protected during the high pressure phase by a valve 31 which is opened by a control means (not shown) in dependence on the reading of the manometer 28 during the onset of the low pressure phase. The suction along the line 15 may be applied by a centrifugal pump 17. The passage of the solution over the wood during the low pressure phase is stated to prevent reabsorption of sap during the subsequent high pressure phase.

The holding means is initially aligned in the Z-X plane by a detecting device 105 having limbs 106, 107. When, e.g. limb 106 strikes the bolt after being moved in the Z direction by motor 104 the rod 108 is rotated to actuate switch 109. The motor 104 drive is stopped and is then reversed by the control means to a position to allow for the diameter of the bolt and the relative positioning of the holding means and limb. Similar movement in the X-direction by motor 102 actuates the switch 110. The detecting device may comprise two sets of limbs (Fig. 10, not shown) spaced apart along the direction of the bolt axis to enable the inclination of the bolt also to be detected as well as its position. If the nut becomes jammed the position of the holding means 115 relative to the bolt is varied incrementally in a step-by-step search pattern around the first position (Figs. 9 or 12, not shown) until the nut is screwed home without triggering the detecting means 410, 412. In the resilient means 113 the detecting means comprise switches 410, 412 actuated by elements 409, 411 with the signals being fed out through slip ring contacts 413-415. In an alternative arrangement (Figs. 15 and 16, not shown) non-contacting detectors comprise light emitting elements operating with a flange or disc. The control system is described which controls the various pulse motors in accordance with memorized information and the control signals from the detecting means.

Abstract: 1452530 Laminates ISOVOLTA OSTERREICHISCHE ISOLLERSTOFFWERKE AG 19 Nov 1974 [21 Nov 1973] 50131/74 Heading B5N A laminate 15 is produced by bringing together at least two continuously fed webs and guiding them under pressure between a heated drum 3 and an endless press belt 6 which moves together with the drum and webs of material, a first web 11 lying nearer the drum consisting of melamine resin-impregnated decorative paper and the adjoining web 13 consisting of vulcanized fibre or an impregnated cardboard, the speed of the belt and the temperature of the drum being such that the residence time of the webs in a pressing region between the drum and belt is sufficient for curing of the melamine resin. Press belt 6, which may be made of rubber reinforced with wire fabric, may be guided over hot water-heated drum 3, deflection drums 4 and tensioning drum 5 in a manner such that the press belt lies against the heating drum over an angle of more than 180 degrees so that it engages more than 50% of the periphery of the  drum. To influence or determine the surface quality of the laminate independently of the quality of the surface of the drum, a separating sheet 20, e.g. of plastics material or aluminium foil, may be guided between the heated drum and webs. For laminates having great flexibility impregnation of the decorative paper may be effected in two stages, first with a melamine resin dissolved in alcohol and then with a melamine resin dissolved in water. Where hard surfaces are required impregnation with the melamine resin dissolved in water may be effected in a single stage with the addition of a hardener, e.g. a salt of a strong acid, to the solution.
