Abstract: 889,023. Disc brakes. DUNLOP RUBBER CO. Ltd. Aug. 25, 1958 [Aug. 31, 1957; Oct. 19, 1957], Nos. 27487/57 and 32698/57. Class 103 (1). In a spring - applied fluid pressure released "spot" type disc brake, the friction pads 7 are normally held in engagement with the disc 1 by means of springs 9 and 10, in compression between pressure members 8 and the closed ends of a cylindrical recess in the member 11. The brake is released by applying pressure, through conduits 20, to the inner faces of pistons 13. A set-screw 21, which may be adjusted as wear of the pads 7 takes place, may be moved to limit the release movement of each piston 13. In an alternative embodiment, the coil compression springs, of which there may be three, are disposed coaxially between two pivoted arms, the lower ends of which act against the friction pads In a further arrangement, the applying springs are disposed to either side of the centrallydisposed fluid-pressure control piston. Specifications 688,382, 732,724, 771,113 and 774,700 are referred to.

Title: Improvements in control rod assemblies for nuclear reactors
IPC: G21C7/16
Filed: 1962-07-19
Abstract: 948,890. Reactor control rods. GENERAL DYNAMICS CORPORATION. July 19, 1962 [Aug. 2, 1961], No. 27906/62. Heading G6C. A nuclear reactor control rod comprises a support rod to which are fixed spacers at intervals therealong, cylindrical neutron absorber elements axially mounted on the support rod between adjacent spacers, and flexible metal discs between each spacer face and the adjacent absorber element end face. The absorber elements 42 and the metal discs 46 are a clearance fit in the control rod guide tube 20, the control rod being axially guided by ceramic rings on each spacer which slide on the guide tube inner surface. Movement of the control rod is effected by a circulating ball nut 64 acting on a leadscrew 62 connected through two releasable couplings 60, 38, to the support rod 22. The leadscrew 62 is rotated by a hydraulic motor 24 having associated therewith an overrun brake 68. The control valves for the hydraulic motor are housed in a portion 70 and include a valve which, in event of an emergency, connects the hydraulic motor direct to a pressurised reservoir above a gas urged piston 84. To remove the functional part of the control rod, the leadscrew casing is removed and a tool inserted to release the upper coupling 38, after which the control rod can be withdrawn upwardly by a fuel handling machine grappling a lifting head 32. The construction described is such as to allow normal working of the control rod in a distorted guide tube, and due to the cushioned axial freedom allowed each portion of the neutron absorber independently of the remainder, control rod damage due to abnormal thermal or mechanical loading is likely to be confined to a limited portion of the overall effective length of the control rod. Inadvertent dropping of the control rod due to any failure in the drive system is obviated by a solenoid operated catch 66.

Abstract: 1,180,966. Fluid-pressure servomotor systems. UNITED AIRCRAFT CORP. June 19, 1967 [July 8, 1966], No.28114/67. Heading G3P. An aircraft cabin pressure control system comprises an outflow valve 14 actuated by controller 16 which latter has a connection with a rate of change controlling diaphragm 20 responsive to a control pressure in chamber 26 communicated from chamber 28 via port 34 and passage 36 and to the same control pressure in chamber 24 communicated via passage 42 and restriction 40. The control pressure is obtained in chamber 28 by an ejector 30 and the diaphragm 20 normally functions to ensure that the rate of change of cabin pressure demanded by controller 16 does not exceed a predetermined value. The diaphragm 20 is, however, rendered inoperative when the cabin pressure departs from the control pressure by a predetermined amount, these pressures being compared by diaphragm 48 which opens valve 56 or 70 to connect chamber 24 direct to the control pressure. A manual control 74 for valve 14 also actuates valve 76 to connect chamber 24 direct to control pressure.

Filed: 1922-10-23
Abstract: 187,634. Brown, C. H. Oct. 24, 1921, [Convention date]. Cataracts and fluid-friction vibration-dampers. -In a shock-absorber for the suspension of motor vehicles &c. and comprising a piston movable within a fluid-containing cylinder to force the fluid through a by-pass adjustable by a valve, the cylinder is arranged between the spring and chassis of the vehicle and the piston has a oneway valve and is actuated by a cam severely to resist downward movement of the chassis and gradually to resist normal return movements. The cylinder 10, Fig. 3, is attached to the chassis and contains a piston 13 prevented from rotating by pins passing therethrough and attached to the cylinder. One of the pins 22 is bored at 23 and has ports 24, 25 forming a by-pass controlled by a needle-valve 26. The piston is normally held up by springs 27, and return of liquid is allowed through a one-way valve 30 held by a spring 34. Above the piston is a cam 32 mounted on a central stud 31 and connected, through the cap 18, to the vehicle spring by an arm 37 and link 38. The upper face of the piston has cam surfaces 41, 42, Fig. 9, which engage with the surfaces 45, 46 of the cam 32. During initial downward movement, the surfaces 45 move down the surfaces 42, allowing the springs 27 to raise the piston. Excessive downward movement brings the sharp inclines 41, 46 into contact, thus quickly forcing the piston down to give an abrupt check. On return, no resistance to movement takes place until the surfaces 42, 45 again contact, where a gradual resistance to movement takes place. The cylinder has a laterally opening filling port closed by a screw plug.
