Patent GB-2109510-A (GB)
Title: Valve
Inventor: UHLY VOLKER
IPC: F16K15/18
Filed: 1982-11-01
Abstract: A valve ball member 4 is held away from a pressure responsive member 3, in the end position shown, by an abutment pin 7, thus permitting flow from an inlet 8 to an outlet 9. Build up of pressure within the valve causes the member 3 to move to the right, the ball 4 moving under the action of a spring 13 to close the valve. A drop in inlet pressure causes the member 3 and hence the ball 4 to return to their initial positions, thus permitting return flow from the outlet. <IMAGE>

Title: Current sensors for ac/dc converter
Inventor: JOHNSON FREDERICK OWEN
IPC: H02M7/162
Filed: 1984-04-13
Abstract: A current sensor for sensing the total DC current flowing in the DC rails of a multiphase converter circuit, which uses SCR's 30, 32, 34, 36, 38, 40, comprises two current transformers 12, 14 coupled to the AC power lines 18, 20 of the converter and another current transformer 16 coupled to the circuit path of a freewheeling diode 60 connected across the DC rails 48, 50 of the converter. An indication of the total DC current flowing through the converter is obtained by summing signals of current flowing in the AC power lines of the converter and the instantaneous pulsed DC current flowing in the DC path of the converter during periods of non-conduction of the switching SCR's in the converter. The sum of the two current signals are obtained by a summing resistor 78 thereby to generate a voltage signal proportional to the instantaneous level of the total DC current flowing through the converter. <IMAGE>

Abstract: A continuously-operable microwave oven arrangement comprises a tunnel-shaped, horizontally disposed treatment zone (1) which is quasi-continuously charged with material to be treated and from which the treated material is discharged without permitting the microwave radiation to leak from the arrangement. This is achieved by providing at least one chamber (5,6,7), each chamber having an individual conveyor means (12, 13, 14) located therein, upstream of the zone (1) and at least one chamber (15, 16), each chamber (15, 16) again having an individual conveyor means (20, 21) located therein, downstream of the zone (1). Displaceable doors (8, 9, 10, 11, 17, 18 and 19) are provided at the upstream and downstream ends of each chamber (5, 6, 7, 15 and 16) and of the zone (1), which doors are microwave radiation-proof.

The movement lies within the focal plane 15 of the lens 10 and is produced by a remote controlled electric motor 14 via rack and pinion gears 12 and 13. Alternatively worm gears may be used (Fig. 4A). The CCD may be sensitive to radiation other than visible light, e.g. Infra-Red, and may be associated with an image intensifier. <IMAGE>
Patent GB-2156290-A (GB)
Title: Rockets and rocket motors
Inventor: EVERARD DANIEL HENRY STIRLING
IPC: F02K9/88
Filed: 1985-03-18
Abstract: It is known to use solid propellent motors to provide propulsion for rockets, these motors requiring a constant combustion rate of the propellant. The invention permits a constant combustion rate of the propellant while providing control of the rocket in the pitch, yaw and roll planes. This is achieved by pulsing the thruster nozzles 6, 7, 8, 9 which allow the gas to exit from the rocket combustion chamber 5, so that a constant number of nozzles, preferably only one, is or are open at any one time thereby providing a constant gas flow out of the chamber. The nozzles described herein may comprise servo-operated on/off plug valves and may be mounted inside the motor combustion chamber. While a solenoid operated ball valve 19 closes a port 18, combustion chamber pressure acts in cylinder 10 on the rear of valve member 11 to close the nozzle. Opening ball valve 19 allows pressure in the cylinder 10 to be relieved through port 18 so that the valve member 11 moves inwards to open the nozzle to the combustion chamber. <IMAGE>

Patent GB-2173674-A (GB)
Title: Paging system
Inventor: POLIAKOFF ALEXANDER
IPC: G08B3/10
Filed: 1985-04-04
Abstract: A paging system includes a local transmitter 15 for transmitting local paging signals to paging receivers 16 over a limited range. An external transmission detector 14 is arranged to detect external area wide transmissions from an external transmitter 18 operating at the same frequency as the local transmitter 15. When such an external transmission is detected, an on-site encoder 11 which includes a memory 12 storing local paging signals inhibits transmission of the local paging signals until the external transmission has stopped. Thus a single paging receiver 16 can be used to receive both external, area wide transmissions and also local transmissions. <IMAGE>

Abstract: A test signal from a generator 10, having a frequency within the range of a signal transmission system, is modulated at 11 by a low frequency signal, from a generator 12, outside the range of the transmission system and is applied to the system 13. The instantaneous peak-to-peak phase jitter of the transmitted signal is detected, 14, and sampled at low and high amplitudes of the test signal to provide respective signals 16, 17 to gates 18, 19. The selector 15 also provides selected low and high level amplitude signals T1, T2 and the ratio T1/T2 is produced at 22. A unit 23 processes the signals T1 and T1/T2 and a unit 24 processes the signal T1/T2. Signal processing circuit, 25-28, output a signal representing true phase jitter, K, and a signal representing noise and interference components, N + I, of the detected jitter. <IMAGE>

Title: Control valve
Inventor: FRETWELL JAMES KEVIN
IPC: F16K39/02
Filed: 1985-09-06
Abstract: A control valve has an annular groove (17) in a closure disc (8), which can cooperate with a seating (7) to isolate an inlet (5) and an outlet (6) from one another. This groove (17) allows, via passageways (15, 16) the fluid upstream of the disc (8) to act on a piston (11) to balance the force acting on the disc (8). Since the groove (17) is located adjacent to the seating (7), the pressure fed to the piston (11) is the mean effective static pressure across the disc (8), thereby enabling the force to be balanced even when the disc (8) moves away from the seating (7). <IMAGE>
