IPC: F15B13/04
Filed: 1969-04-21
Abstract: 1,258,345. Valves. BORG-WARNER CORP. 21 April, 1969 [1 May, 1968], No. 20348/69. Heading F2V. [Also in Division F1] A manually-operable spool 70 is moved either side of the neutral position shown to connect a pressure inlet 154, that is supplied by a variable-displacement swash-plate pump 12, to one of a pair of work ports 64, 65 connected to the opposite ends of a double-acting pistoncylinder 11. One of a pair of control ports 76, 83 is simultaneously connected to the work port which is connected to the inlet so that the work pressure is communicated via line 160 to a piston-cylinder 22 acting on the swash-plate 20 and which is opposed by a smaller-diameter piston-cylinder 21 connected to the pump outlet. The outlet pressure of the pump is thus controlled according to the work pressure which in turn is responsive to the load on the piston-cylinder 11 and the position of the spool 70. In the case of the pump being engine-driven variation of outlet pressure with speed is also compensated for. Check valves 115, 116 having seats 105, 106 permit one control port at a time to be connected to line 160 while the other which is connected to one of the exhaust ports 75, 84 is blocked from line 160 by the pressure therein acting on the respective valve member to hold it closed A relief valve 14 between the pump outlet and exhaust has in addition to the loading spring 50 a fluid-loading determined by the pressure in line 160 so that it will be maintained closed while the spool is in an actuated position but will be able to relieve when the spool is in neutral position. Ball valve 41 acts to relieve the pressure in line 160. Variable displacement vane and radial piston pumps may be similarly controlled. In a modification with a constant-displacement pump relief valve 14 controls the pump outlet pressure in accordance with the work pressure.

In a system for automatically adjusting the orientation of the light beam emitted by a vehicle headlamp, light from the lamp filament 13 passes via elliptical mirror 17, at whose one focus F 2  the filament lies, to a convex parabolic mirror 15 mounted on a pivot 16 at its focus which is coincident with the other focus F 1  of the elliptical mirror, the orientation of this pivoted mirror being controlled by transducers 1 and 2 which are responsive to the changes in position of the front and rear suspension units of the vehicle. Electrical signals from the transducers pass through a differential amplifier 6 to a coil surrounding a magnetized plunger core 8 of the repulsion type connected via link 19 to the pivoted mirror 15. Plunger core 9 in transducer 10 feeds information about plunger movements back to differential amplifier 6. The parabolic mirror 15 may be mounted on a horizontal axis for controlling lamp orientation due to changes in vehicle attitude, or on a vertical axis for automatic control of a cornering light.

Abstract: 1329902 Transponder systems A C COSSOR Ltd 22 June 1972 [30 July 1971] 36032/71 Heading H4L A transponder is provided with switching means adapted to place the transponder in a first mode in which it will respond only to a general call interrogation signal or in a second mode in which it will respond only to an interrogation signal selectively addressed thereto, and an automatic control circuit for the switching means operative in the first mode to set the transponder to the second mode when the transponder has made a predetermined number of replies to a general call interrogation and operative in the second mode to set the transponder to the first mode when the transponder fails to receive a predetermined number of interrogations selectively addressed thereto within a predetermined time. As shown, a shore station 1 tracks a plurality of ships each carrying a transponder 2. The shore station transmits at frequency f 1  and includes a computer 4 which stores the address codes of the vessels together with their co-ordinates in known manner and causes each vessel to be interrogated by its address code when the aerial 3 is on the correct bearing for that vessel. Periodically, the computer causes the selective address signals to be replaced by a general call to which none of the transponders which have already been acquired replies. Replies are received at the shore station via an omnidirectional aerial 15 and receiver 16. If the response is to a selective address signal the store is updated accordingly and if it is in response to a general call, this is registered in the store whereby the vessel responding is acquired for tracking. The transponder is provided with decoders 8 and 9 for the selective and general code respectively, whose outputs are fed via gate 10 or 11 respectively and via OR gate 12 to trigger the transmitter 12 to transmit the reply code on frequency f 2 . A bi-stable 17 determines which gate 10 or 11 is enabled and is controlled by monostables 18, 19. When the bi-stable 17 is set, the gate 11 is enabled and a counter 21 produces an output when a predetermined number of general calls have been received and this resets bi-stable 17 to enable gate 10. If no selective code arrives during the delay period of monostable 18, this circuit resets and after a further delay produced at 20 the bi-stable 17 is set for the general call. To prevent two vessels from replying to a general call simultaneously, the delay 20 is arranged to vary in a random manner.
