Patent GB-2260456-A (GB)
Title: Method of assessing received radar pulses
Inventor: GAILER JAMES MARTIN
IPC: G01S7/292
Filed: 1987-08-19
Abstract: The method comprises the step of comparing various characteristics of a pulse with the moan value of the respective characteristics for pulses previously received. Using a probability process, confidence values for the pulse can be calculated. By combining the confidence values for each characteristic, an overall confidence value is obtained for the pulse so that it can be identified as being from a particular target. Characteristics assessed include target angle, pulse power level, pulse width and pulse repetition rate. <IMAGE>

Switch means 15 are mounted to the appliance for electrically isolating said pin connector from the appliance when the appliance is not engaged with the base unit, the switch means comprising a pair of contacts associated with a spring mechanism which maintains the contacts open until such time as the appliance is engaged with the base unit, an operating member 22 being coupled to the spring mechanism and being arranged to co-operate with a part of the base unit or socket connector thereof when the appliance is engaged with the base unit so that the spring mechanism operates to close the contacts by snap-action to permit power to be supplied to the appliance, the spring mechanism also operating to open the contacts by reverse snap-action when the appliance is disengaged from the base unit. The switch means 15 is mounted between the pins 17 and the conventional terminal pins (at 30) of the appliance. The pins 17 are vertical or sloped (see figure 4, not shown). <IMAGE>

Patent GB-2372375-A (GB)
Title: Graded layer passivation of group 2-6 infrared photodetectors
Inventor: COCKRUM CHARLES A
IPC: H01L31/0216
Filed: 1989-05-05
Abstract: A Group II-VI IR photodiode 10 has a passivation layer 16 overlying at least exposed surfaces of the p-n diode junction 15, the passivation layer being a compositionally graded layer comprised of Group II atoms diffused into a surface of the p-n diode junction. The passivation layer has a wider energy bandgap than the underlying diode material thereby repelling both holes and electrons away from the surface of the diode and resulting in improved diode operating characteristics. A cation substitution method includes the steps of preparing a surface to be passivated, such as by depleting an upper surface region of Group II atoms; depositing a layer comprised of a Group II material over the depleted surface region; and annealing the deposited layer and underlying Group II-VI material such that atoms of the deposited Group II layer diffuse into the underlying depleted surface region and fill cation vacancy sites within the depleted surface region. The resulting passivation layer is a compositionally graded layer having an energy bandgap which gradually decreases in value as a function of depth from the surface until the bandgap energy equals that of the underlying bulk material. The preparation of the surface may also be accomplished by providing a body of Group II-VI material which has a substantially stoichiometric composition.
Patent GB-2232620-A (GB)
Title: Feeding abrasive material
Inventor: HERON ROGER ARTINDALE
IPC: B24C7/00
Filed: 1989-06-15
Abstract: When an abrasive mixture is supplied through conduits (191) containing valves (309), considerable wear is experienced by the valve when it is operated with abrasive material within it. The present invention aims to reduce wear on such valves by providing means (193, 308) to flush the valve before operation so that the abrasive material content is reduced preferably to zero. This avoids abrasive particles becoming caught between working parts of the valve and causing undue wear. When the conduit leads to a nozzle (222) from which the abrasive mixture is jetted for cutting purposes, the flushing of the valve will cause a reduction in the concentration of abrasive mixture at the nozzle in the normal circumstances. In order to avoid this reduction of concentration, the outlet of the valve can be fed to the nozzle through an abrasive mixture reservoir (310) which will smooth out variations in the abrasive mixture concentration and so maintain the efficiency of the jet from the cutting nozzle.

Title: Liquid level control float valve
Inventor: DICKINSON MARK JOHN
IPC: F16K31/34
Filed: 1991-11-20
Abstract: A float valve consisting of a modified washing machine-type liquid control pilot-operated diaphragm valve is constructed, whereby the control plunger, normally operated electromagnetically, is moved instead mechanically by the vertical movement of an indirectly-linked float 16. A positive toggle action is achieved by float buoyancy suddenly overcoming resistance offered by a stressed flexed sheet 18 of suitable material. The float linkage thereby becomes de-linked mechanically from the plunger after valve closure. An alternative method of achieving this cistern overfill at valve closure using magnetic attraction is also described. <IMAGE>

Patent GB-2255224-A (GB)
Title: Method and device for controlling cutting of a spacer wire of nuclear fuel rods
Inventor: CICCARIELLO JEAN-CLAUDE
IPC: G21C19/36
Filed: 1992-04-10
Abstract: The device is able to detect if the cutting of the spacer wire (1) of a fuel rod (20) has effectively occured, in particular in the case where the cutting of the wire spacer (1) is effected with the aid of an electrode cassette (25). The device uses a contact cone (10) on which the spacer wire (1) is scoured after the cutting. If the cut has not effectively occured, the section needing to be cut is still raised to its cutting potential (VC). The detection of the latter makes it possible to detect the absence of cutting of the spacer wire section and thus to direct further cutting of the wire at the same position. As the contact piece (10) is rotating in correspondence with the forward movement of the spacer wire (1), the connection to the comparison means (22) is effected by means of one connection track (8) and one collecting brush (12). The device is used for cutting of the spacer wire of nuclear fuel rods irradiated in fast neutron reactors. <IMAGE>
