Patent GB-2206019-A (GB)
Title: Radio repeater architecture
Inventor: CHILDRESS JEFFREY SCOTT
IPC: H04L1/16
Filed: 1988-06-03
Abstract: A site architecture for a trunked radio frequency communications system provides better fault tolerance capabilities than are available from architectures including redundant hardware. During normal system operations, a primary site controller 410 performs most or all system control functions while signal processing functions are performed in a distributed manner by trunking cards 400, 402... associated with individual repeater channel receivers and transmitters. If the site controller 410 fails, the trunking cards also begin performing trunking and other control functions. The trunking cards cease attempting to communicate with the failed site controller, and begin communicating directly with one another via a high speed backup serial link. Through the distributed processing routines performed by the various trunking cards and interaction between the trunking cards over the backup serial link, trunking and other capabilities are maintained even though the primary site controller has failed (although advanced features such as call logging and the like are lost). Because trunking capability is maintained, failure of the primary site controller has little or no effect on ongoing communications and is virtually transparent to mobile unit operators. <IMAGE>

Patent GB-2208363-A (GB)
Title: Shearing machine
Inventor: OGASAWARA KAZUI
IPC: B21D43/22
Filed: 1988-07-28
Abstract: The machine has a ram 19 provided with an upper blade 17 which shears in cooperation with a lower blade 15, a conveyor 23, for supporting the workpiece downstream of the blades and for discharging sheared plates, and elevation means 63 for causing the upstream end of the conveyor 23 to descend immediately before, or simultaneously with, the start of the shearing of the workpiece. The elevation means 63 includes a slide 77 driven by an eccentric 89 which may be mounted on the same drive shaft 33 as an eccentric 35 driving the ram 19. The conveyor 23 is movable horizontally by a cylinder 73 to open up a gap for scrap to fall onto a shoot 95. Sheared plates are guided by a pivotable plate 125 onto a vertically-movable storage table 111. There may also be a variable-pressure hold down 31.

Title: Hydraulic cylinder assembly for clutch control
Inventor: BARKER DAVID CURTIS
IPC: F15B7/08
Filed: 1988-08-31
Abstract: A hydraulic cylinder assembly (12) includes a plastic cylinder body (32) open at its forward end (32a) and having an end wall (32b) at its rearward end and defining a cylindrical bore (32c) extending from the open forward end to the end wall; a piston (34) mounted for reciprocal sliding movement in the bore; a push rod (36) coupled to the piston and extending out of the open forward end of the cylinder body; and spring means (38) interposed between the end wall of the cylinder body and the piston. The spring means comprises metallic front and rear coil springs (48,46) having adjacent ends seated in an annular plastic coupler member (50). As the spring assembly expands and contracts in response to actuation of the cylinder assembly, the plastic coupler member maintains the springs in precise axial alignment and precludes buckling and consequent scouring of the plastic surface of the cylinder bore by the high carbon steel of the springs and minimizes the stresses developed within the springs during the cycling of the apparatus. <IMAGE>

Patent GB-2238357-A (GB)
Title: Power unit for hydraulic elevator
Inventor: USIDA HIROSHI
IPC: B66B1/24
Filed: 1990-09-18
Abstract: A hydraulic elevator power unit has an oiltight type detector 10 for detecting the speed of an electric motor 3 driving a pump 4 supplying a hydraulic jack 9. The motor, pump and detector are immersed in a reservoir 1 for the operating oil whereby the detector is at risk of malfunctioning if oil enters thereinto past a seal 11. A leak oil hole 15 is therefore formed in a lower end portion of the detector and is connected to a leak oil tank 16. Operating oil entering the detector is discharged through the leak oil hole, thereby preventing the detecting portion from being immersed in the operating oil. The leak oil tank may be located inside or outside the reservoir 1. <IMAGE>

Filed: 1992-06-15
Abstract: An air supply system comprises one regulator through which air flows into a plurality of helmets via branching tubes. A throttle valve, a flowmeter and a coupling device are joined to each branching tube. At the throttle valve, because the ratio in pressure of the upstream to the downstream is larger than the critical pressure ratio, air rate supplied to each helmet is not affected, but is constant without additional regulators or cocks on the branching tube when each diver dives at different depth and/or if the helmet is removed from the coupling device. <IMAGE>
