Abstract: 978,764. Elevated railways. J. HOHLA. Nov. 20, 1961 [Dec. 2, 1960; March 1, 1961], No. 41362/61. Heading B7L. In a continuous beam structure for supporting loads movable on the structure such as rolling loads of a crane track, the continuous beam is connected to supports spaced along its length through the intermediary of hydraulic or pneumatic supporting elements each capable of yielding under load and each such element is connected to an hydraulic or pneumatic counterpressure device independent of the supporting structure to effect a pre-loading of the elements. In the arrangement shown in Figs. 1 and 2, a rail 1 is supported on stanchions 2 through the intermediary of an hydraulic piston 9 and cylinder 10, supports 3. The supports 3 are connected singly or in groups by a pressure line 4 to a counter-pressure system 5 operating under a dead-weight 6. Up to the limit of the pressure in the system the supporting structure acts as a continuous beam with rigid supports, but above the limit the downward movement of the rail 1 and hence the piston 9 acts, through the pressure medium, against the weight 6. In an alternative arrangement shown in Fig. 3, the system 5 is replaced by a piston 20 and cylinder 15 connected to a pivoted lever 16 connected to a weight 17 in a cylinder 18 immersed in a fluid in a container 19.

Title: Improvements in or relating to electrical selecting apparatus
IPC: G08C15/06
Filed: 1960-12-12
Abstract: 926,303. Variable speed sampling. GENERAL ELECTRICAL CO. Ltd., and A. G. BLAY. Dec. 12, 1961 [Dec. 12, 1960], No. 42707/60. Class 40 (3). [Also in Groups XXXVI and XXXVIII] In an apparatus for the selection of certain ones of a plurality of thermocouples for sequential connection to recording means, for example a printer, a scanning means scans all the inputs in turn at a high rate, the scanning being reduced to a low rate whenever a selected input is reached. Selection is by way of a plugboard. In the embodiment described there are 180 inputs 1 which are connected one at a time to the output line 2 by relays 9, which are controlled by diode matrix 8. A counter 3 causes the matrix 8 to be scanned, but the input corresponding to the instantaneous count is connected to the output line 2 only if the counting rate is sufficiently slow. The counter receives very high speed pulses on line 11 and low speed pulses on line 10. Two plugboards 15, 16, each comprising a 10Î10 matrix of junctions, are fed with the outputs of the " tens " and " units " stages of the counters. These boards correspond to thermocouple inputs 000-099 and 100-199. By inserting a plug in the board a corresponding input is selected. Normally the counter counts fast pulses on line 11, but when the count reaches a value indicated by the position of a plug in the plugboards a circuit will be completed and gate 11 will be inhibited. A slow clock pulse on line 10 then causes the relays to connect the correct input to the output line for recording. At the next slow pulse, if the count then indicated is not indicative of a selected input, the gate 12 again passes fast pulses and is not again inhibited until the next selected input is reached.

Abstract: 1,087,747. Rotary pumps and motors. A. FEROY. Oct. 12, 1965 [Nov. 9, 1964], No.43207/65. Heading F1F. A rotary hydraulic pump or motor of the sliding vane, multiple abutment type, comprises a rotor 12, Fig. 1, fixed to a shaft 62 journalled in end members 14, 16 formed respectively with inlet' and outlet passages 54, 60 which communicate with annular chambers 38, 40 and which members together with outer end plates 20, 22 form pressure balancing chambers 88, 70. In the case of a motor, pressure liquid supplied to the passage 54 and annular chamber 38 passes through arcuate ports 56 in the member 14 into working chambers 26, 28, Fig. 2, of the motor formed between vanes 32 slidable in radial axially-extending slots 30 in the rotor. Discharge from the working chambers takes place through arcuate ports 58 in the member 16, annular chamber 40 and passage 60. To prevent or at least reduce leakage between the rotor end faces and the adjacent faces of the members 14, 16 due to the outward bowing of the members 14, 16 in the high-pressure areas of the motor, the members 14, 16 are of one piece rigid construction and liquid at supply pressure is admitted through a port (or ports) 82 in the member 14 registering with the bottoms of the vane slots 30 and valve-controlled passages 94, 80 to the pressure balancing chambers 88, 70 to counterbalance the outward bowing of the members 14, 16. At this stage, passages 76, 98 in the members 16, 14 communicating with the low-pressure working chambers are closed by ball valves 78. 102 subjected to the higher-pressure in the balancing chambers. The inner ends of the vanes 32 are cut away at their ends and engaged by arcuate push rods 108, 110 slidable in grooves and sealed where they cross-over by a sealing element 112, Fig. 6, which prevents pressure liquid in the deeper of the two grooves acting on the side face of the rod 110 resulting in consequential reduction in friction between the rods and grooves. Flat springs 118 urge the vanes 32 radially outwards. Operating as a pump the valve-controlled passages 94, 80 are now closed by respective ball valves 96, 84 and the valves 102, 78 whose passages 98, 76 are now associated with the high-pressure discharge side of the pump are unseated.
