Title: Gettering vacuum systems
IPC: H05H1/00
Filed: 1979-10-26
Abstract: A gettering system for removing radioactive hydrogen isotope containing hydrocarbon bases from a hermetically sealed fusion reactor system to which the gettering system is coupled, includes an electron source 32 and means for accelerating the electrons to produce collisions with the hydrocarbon gas present in the system to dissociate the gas and a hydrogen and radioactive hydrogen isotope gas regenerable getter pumping means 36, e.g. a zirconium- aluminium alloy getter, is included within the system for adsorbing these gases from the system.

Title: Automatic electrical switching apparatus
IPC: H05B37/02
Filed: 1981-03-26
Abstract: To enable electric lights and other electrically actuated devices in a building to be switched on and switched off at prearranged times, an electrical switching apparatus has a clock pulse generator 14, 15 which supplies clock pulses to a binary counter 16 while a start gate 17 is open. The start gate 17 is controlled by a flip-flop 19 which is set to open the gate 17 by a signal coupled from a light actuated switch 12 and is reset after several hours to close the gate 17 by a signal occurring at a predetermined count in the counter 16. The contents of the counter 16 whilst it is counting is decoded by a programmed memory 20 coupled to a binary to decimal decoder 21. Chosen counts in the binary counter 16 serve as addresses for on and off signals encoded in the memory 20 and applied to relays 11 connected in the energisation circuit of a device e.g. an electric lamp. The memory 20 can be programmed so as to cause lights and other devices in a building which is unoccupied to be operated in a manner giving an impression that the building is occupied. <IMAGE>

Patent GB-2081535-A (GB)
Title: Continuity monitoring system
IPC: G08B29/06
Filed: 1981-07-16
Abstract: The continuity of an elongate member, for example an electrical conductor (particularly an overhead conductor in an electric railway system), is monitored with the aid of a monitor conductor or optical fibre. In one embodiment, a monitor conductor in the form of an optic fibre 34 is continuous with an overhead conductor 16. Light source 32 provides a light signal in fibre 34. Means 36, which includes a light-responsive device 40 and a coil 42, is linked to source 32 by the fibre 34. If, for example, ground movement or a rock fall (in an underground railway) causes a discontinuity in the conductor 16, the concomitant damage to fibre 34 will result in signal loss thereby causing an indication of loss of continuity to be given. Additionally, the conductor 16 can be isolated from the supply. Electrical monitoring systems are also proposed. The monitor conductor may be located internally or externally of the elongate member. <IMAGE>

Title: Separating and removing groups of sheets and signatures from a stack
IPC: B65H29/06
Filed: 1981-10-05
Abstract: A rotating separator (46) separates a group of sheets or signatures from a stack to an intermittently rotating set of grippers (14) which then removes the separated signatures and place them on conveyor (11). The signatures are then conveyed to gatherer (13) for a binder. A sensor (42) activates the intermittent movement of the separator (46) and the grippers (14) when it senses a low level of signatures in the gatherer (13). The separator (46) can be a brush- or irregular-surfaced roller. <IMAGE>
Patent GB-2090025-A (GB)
Title: Watch circuit with oscillator gain control
IPC: G04G19/00
Filed: 1981-12-15
Abstract: A watch circuit arrangement for conserving battery power includes a feedback connection between the crystal oscillator of the watch circuit and the display voltage generator which is responsive to the crystal oscillator output to develop sufficient output voltage for the watch display. Specifically, the output of the display voltage generator, which may be a voltage multiplier, is sensed by a display voltage sensing circuit which controls the gain of the crystal oscillator. Initially, when battery power is applied to the watch circuit, the voltage multiplier has zero output voltage, which conditions the crystal oscillator to have a sufficiently high gain to start the oscillator. After several cycles of oscillator signal, the voltage multiplier output increases, which conditions the crystal oscillator to have a lower gain for reducing power consumption while sustaining oscillation.
