Patent GB-2105121-A (GB)
Title: Pulse circuits
Inventor: RICHARDSON ROBERT
IPC: G01S7/282
Filed: 1981-08-08
Abstract: A pulse circuit uses a transformer 3 to convert a high current pulse at relatively low voltage into a very high voltage pulse which is able to directly drive a magnetron oscillator. The circuit forms part of a radar transmitter in which the transmitted pulse lengths are to be varied. It is not satisfactory to alter the structure of the transformer or that of a pulse forming network which is used to feed the transformer when variation in the pulse length is required. The invention provides a bias circuit 30 which magnetically biasses the core material of the transformer, so that when a pulse is subsequently applied to the transformer the flux of the core material saturates after a predetermined interval of time which is dependent on the bias level. In this way accurate control of pulse length can be achieved and the characteristics of the pulse forming network and the transformer are used to determine the rising and falling edges of microwave pulses generated by the magnetron. <IMAGE>

Title: Process an apparatus for separating a mixed gas such as air
IPC: B01D53/047
Filed: 1981-12-09
Abstract: The invention relates to a process and apparatus for separating mixed gas by adsorption in which adsorption and desorption steps are repeatedly carried out in a plurality of adsorption towers in staggered timings, wherein to commence a desorption step, mixed gas delivered from an adsorption tower which has completed adsorption during a primary pressure-reducing period in said adsorption tower, is fed to another adsorption tower which has been raised in pressure up to an intermediate pressure between the adsorption pressure and the desorption pressure, after termination of the desorption step, by an unadsorbate gas delivered as a result of low-pressure adsorption and/or mixed gas delivered during the primary pressure-reducing period, to carry out a low-pressure adsorption step in which the adsorbate constituent gas in said mixed gas is made to be adsorbed, whereby a pressurized mixed gas having a low adsorbate constituent concentration which is delivered during the primary pressure-reducing period can be effectively utilized.
Patent GB-2091052-A (GB)
Title: Circuit for controlling electric drives
IPC: H02M7/5387
Filed: 1982-01-13
Abstract: An analog-to-digital converter (12) is used in a circuit for controlling electric drives, using a rectifier (1), a DC controller (2) and an inverter (3). A desired output frequency value Fin is thereby converted and addresses a store (10) whose particular address represents a control value proportional to the desired output voltage of the inverter. After conversion in a digital-to-analog converter (14), the control value is fed to the controller (2) as a desired value, thus ensuring the optimum utilisation of energy. Different voltage frequency ratios may be selected by means of a selector (11) which enables different stored values to be addressed. <IMAGE>

Title: Gasketing of heat transfer plates
Inventor: SHORE DAVID TEIGNMOUTH
IPC: F28F3/10
Filed: 1982-04-05
Abstract: In heat transfer apparatus of the plate type, gaskets around the plates are normally elastomeric gaskets fixed by adhesive into pressed recesses in the plates.

Title: Control circuit for heater
IPC: F02N19/04
Filed: 1982-05-07
Abstract: A control circuit for controlling the operation of an electrically powered heating device 12, particularly in an I.C. engine starting aid, includes supply terminals 10, 11 for connection to a source of d.c. supply the voltage of which may vary in use of the heater, one terminal of the heater 12 being connected to terminal 11 and the other terminal of the heater 12 being connected to the other terminal 10 via a relay contact 13. The junction of the contact and heater is connected via a resistor 19 to one plate of a capacitor 17 the other plate of which is connected to the terminal 11. A comparator 15 monitors the voltage across the capacitor and controls the operation of a relay winding 14 which actuates contacts 13. The comparator is supplied with a reference voltage 16 which is chosen in dependence on the values of resistor 21, 22 and the design voltage of the heater 12, the design voltage being lower than the nominal voltage of the d.c. supply. The relative values of resistors 18, 19 are chosen so that when the supply voltage exceeds the design voltage the power supplied to the heater 12 is controlled by repeated operation of contact 13. A positive feedback resistor 20 is provided to give a rapid operation of the relay. <IMAGE>

Patent GB-2119158-A (GB)
Title: Blanket management method for liquid metal fast breeder reactors
Inventor: CARELLI MARIO DOMENICO
IPC: G21C5/20
Filed: 1983-04-22
Abstract: A method for reducing thermal striping in liquid metal fast breeder reactors by reducing temperature gradients between adjacent fuel and blanket assemblies by shuffling blanket assemblies at each refueling outage so as to progressively shuffle the blanket assemblies to the core periphery through multiple moves and to generally locate fresh blanket assemblies adjacent to exposed fuel assemblies and exposed blanket assemblies adjacent to fresh fuel. Additionally, assembly orificing is altered to provide less flow to blanket assemblies needing less flow due to an otherwise decreased temperature gradient and providing additional flow to fuel assemblies which need more flow to sufficiently reduce temperature gradients to prevent thermal striping.

IPC: H01R13/631
Filed: 1983-05-20
Abstract: The housing of an electrical connector assembly includes a respective channel 21 at each end thereof which opens towards the rear of the housing. A deepened section 23 of each channel 21 presents a face 24 towards the opening thereof. An insertion tool (not shown) has a plurality of arms spaced apart by the same distance as the channels 21 and provides a grip at a distance from the rear of the housing to facilitate connection of the assembly to a corresponding assembly which may be surrounded by other connector assemblies thus preventing gripping the assembly by hand. A disengagement tool (Figure 7) has a plurality of arms 25 spaced apart by a corresponding distance to the channels 21. Each of the arms has a locking member 27 arranged to cooperate with the faces 24 of the channels to facilitate removal of a connector assembly from a corresponding assembly. The disengagement tool is preferably of a plastics material which has sufficient resilience to enable the arms 25 to flex to permit insertion of the arms 25 in the channels 21. <IMAGE>

Patent GB-2145166-A (GB)
Title: Tidal power method and apparatus
Inventor: CHOI IN KYU
IPC: F03B13/26
Filed: 1983-08-18
Abstract: Tidal power apparatus includes a buoyancy vessel having a variable-buoyancy chamber 2 and a fixed-buoyancy chamber 3. As the tide rises, the vessel is subsequently released so that it rises and drives a pump 11 through a variable ratio transmission including conically wound gears. Water is pumped from the chamber 2 to a reservoir 18 supplying water to electricity generating means which discharges the water to a reservoir 17. The vessel is held at its upper position and balanced by means of a flood gate. The chamber 2 is then supplied with water from the reservoir 17 and as the tide drops, the vessel is released. This drives the pump 11 to pump water from the sea into reservoir 18 to provide further drive power to the generating means. The vessel is then held at its lower position and balanced by means of the flood gate. At high tide, the cycle is commenced again. Movement of water is controlled by a four way valve 12. <IMAGE>

The hub sleeve (3) can be removed from the drive member (5) and fitted on to it again without problem after the removal of the insertable second spindle part (23). The hub sleeve and spacer (71) are clamped in position by a cap (43) cooperable with eccentrics (41) on a pin having a hand lever (45). <IMAGE>
