Title: Fluid-actuated clamping apparatus and circuit
IPC: F15B11/02
Filed: 1975-11-26
Abstract: 1476077 Fluid-pressure control circuits CASCADE CORP 26 Nov 1975 [29 Aug 1975] 48569/75 Heading F1P In a load clamping device for a lift truck, arms 18, 20, Fig. 2, are moved by actuators 22, 24 which are connected in series by the circuit shown when neither arm is obstructed and in parallel when either arm is obstructed. When both arms are unobstructed fluid is supplied through conduits 40, 80, shuttle valve 56 and conduits 92, 50 to chamber 34b of motor 24. Fluid is displaced from chamber 34a of motor 24, through conduit 52, valve 66 and conduits 96, 46 into chamber 28b of motor 22. Because of the difference in crosssection of the motors 22, 24, both arms 18, 20 move the same distance. Fluid from chamber 28a of motor 22 passes through conduits 48, 42 to exhaust. When one of the arms is impeded, pressure increases rapidly in conduit 40 compared with conduit 42 and when this reaches a certain limit actuator 76 begins to shift spool 70 to the left. Flow now takes place through conduits 110, 112 and conduits 114, 116 are interrupted. Actuator 74 is now pressurized and in co-operation with actuator 76 it causes rapid movement to the left of spool 66. This connects the motors 22, 24 in parallel. A pressure drop now occurs in conduit 40 but the valve 66 is held in its left position because even at a lower pressure the combined effect of actuators 76, 74 overcomes the return means 78. To release a load, fluid is supplied through conduit 42. Actuator 72 returns the valve 66 to the position shown in combination with means 78. During opening of the arms fluid from chamber 34b passes through the shutter valve 56 and enters conduit 42 so that the opening movement is accelerated. Fig. 3 (not shown), illustrates a modification in which the arms may be moved sideways in unison. Conduits 146, 154 provide for this and the circuit operates as described above in other respects.

Title: Improvements in vehicle braking systems
IPC: F16D65/56
Filed: 1963-12-11
Abstract: 1,029,800. Automatic brake-adjusters. H. TEVES, E. A. TEVES, and M. TAUSEND. Dec. 11, 1963 [Jan. 3, 1963], No. 48934/63. Heading F2E. A duo-servo brake has a turnbuckle-type slack-adjuster interconnecting the end of brake shoes 1 and 2 and whose slack-adjusting sleeve 6 has a unidirectionally operating ratchet wheel 11 engaging a tooth 24 of a lever 10 pivoted on the brake shoe leading at rearward travel and having an end 25 which engages with a stop on the brake carrier when the brake is off. The stop is at one end of a fixed guide-block 5 in bores 22 in which the sleeve 6 is slidably supported. One end of the sleeve in the bore 22 is machined to full diameter and the other end is brought out to the same diameter by a sleeve 17 fixed by a circlip 16, thus forming shoulders 15 against which disc washers 18 and 19 abut. A spring 7 between the washers normally centralizes the adjusting sleeve 6 relative to the block 5. The lever 10 is pivoted at 23 on the shoe 2 and is urged against the stop by a spring 23. When braking at forward travel (as indicated by the arrow) the shoe 1 is dragged by the drum and acts through the adjuster on the shoe 2 to force it against the drum wall so that the shoes, the lever 10, the ratchet wheel and the sleeve all move together releasing the end 25 from the guide stop and compressing the spring 7. When the brake is released the parts return to their initial positions without brake adjustment. When the brake is applied in reverse the shoe 2 acts on the shoe 1 through the adjuster. The end 25 of the lever 10 rides up on the block 5 so that the tooth 24 jumps over one or more teeth of the ratchet 11 depending on the state of wear of the shoes. On release, the spring 7 re-centres the sleeve 6. The end 25 of the lever 10 remains against the stop whilst the lever 10 turns (as shown by the arrow) on its pivot 23 so that the tooth 24 rotates the ratchet wheel 11  to adjust the length of the tappets 8 and 9.

Abstract: 1,069,137. Capacitors. SIEMENS A.G. Dec. 9, 1964 [Dec. 10, 1963], No. 50034/64. Heading HIM. A method of manufacturing a regenerative capacitor includes vapour depositing a metal layer 11 on a first varnish film 10 and applying a swelling agent to the exposed surface of the metal layer, such that the swelling agent passes through pores in the metal layer and swells the varnish film so as to form cracks in the metal layer (see Fig. 1). The swelling agent may be applied in vapour form or as a solvent in liquid form containing a solute that on evaporation of the solvent forms a second varnish film 12 on the exposed surface of the metal layer. Paraffin oil or silicone oil to restrain the operation of the swelling agent may be deposited on the metal layer before the swelling agent is applied, or it may be included in a liquid which on solidification forms the first varnish film, or it may be present in the solvent applied as swelling agent. Two such capacitor strips comprising varnish films 10, 12, e.g. of acetyl-cellulose, may be rolled together, a marginal strip 13 of the metal electrode layer 11 being left free from cracks. Either one of the varnish films 10 or 12 may be a dielectric film, or the dielectric may be formed by a paper or a non-swelling or insoluble plastics backing strip upon which the first varnish film 10 is deposited.
