Patent GB-2131552-A (GB)
Title: Non-destructive testing using eddy-currents
Inventor: BONESS KENNETH DUNCAN
IPC: G01N27/90
Filed: 1983-11-23
Abstract: A method for testing a specimen by means of eddy currents generated within the specimen comprises applying an electrical energy pulse from source I to a tuned circuit (1) which incorporates a probe coil (4), allowing the tuned circuit to reverberate freely in response to the energy impulse, measuring the rate of decay and oscillatory period of the reverberations and deriving therefrom a measure of the resistive and reactive components of the impedance of the probe coil and hence the condition of the specimen. Various forms of arrangements and methods are described for measuring the rate of decay and oscillatory period. <IMAGE>

Title: Electric heating appliance
Inventor: MCDONALD TONY RONALD
IPC: A47J27/62
Filed: 1984-02-01
Abstract: The heater Lo of an appliance, particularly a kettle, is turned off by a relay RL controlled by a transistor TR1 when steam is sensed by a temperature sensing diode D7. A boil-dry sensing diode DX may also be provided. The heater Lo is initially energised in response to closure of a push button switch SW1, a capacitor C3 charging more slowly than a capacitor C1 so that there is an irritive delay before transistor TR1 turns on, thereby allowing the power supply for the control circuit to reach a stable state. A permanent connection may be provided instead of switch SW1 so that the circuit is changed from one-shot operation to cycling operation to maintain a selected temperature when the appliance is an electric iron, a water heater, or a cooling appliance such as a fryer. A switch may and cycling operation. A thermistor may be used in an electric iron in place of the temperature responsive has a diode (D11), (Figure 5) to sense water temperature and a temperature selector (R21), the heater Lo being turned off in response to sensor D7 when selector (R21) is at a maximum position and in response to sensor (D11) below the maximum. In other embodiments the relay is replaced by a triac (TH1) or (TH2), (Figure 6,7) triggered at zero crossings. Other types of appliance referred to are spaced heater, toasters and hot plates on cookers. <IMAGE>

Title: A cavity closer and cavity wall construction
Inventor: MOLYNEUX GEORGE
IPC: E06B1/00
Filed: 1984-05-10
Abstract: An extruded plastics cavity closer, for use at the ends of cavity walls, adjacent to an opening for a door or window frame, comprises a strip of water-resistant, moisture- impermeable material, the strip locating on the jamb 16, head or sill of the door or window frame, and having a part which bridges the cavity and provides a hollow structure which when substantially filled with mortar provides a mortar fire barrier which closes substantially the full width of the otherwise open end of the cavity. In one form of the invention, the cavity closer has an outer frame- engaging part which is adapted to fit between an end of the wall and the door or window frame member, and an inner part extending to one side of the outer part but offset from it so as to provide a reveal for the mortar fire barrier. <IMAGE>

Title: Cassegrain aerial system
Inventor: NEWHAM PAUL
IPC: H01Q19/19
Filed: 1985-06-29
Abstract: A high bandwidth microwave antenna feed for a Cassegrain aerial having a main reflector 1 and a sub-reflector 2 comprises a spigot 4 of relatively high dielectric constant protruding from a conventional hollow waveguide 3 and a generally conical member 12 of relatively low dielectric constant fitted coaxially with, and expanding from, the protruding spigot 4. The base portion of the conical member is silvered and constitutes a sub-reflector 2. In use, microwave radiation from the hollow waveguide is refracted at the spigot/conical member interface and is reflected from the sub-reflector to the facing main reflector 1. The two-part dielectric construction enables the dimensions of the sub-reflector to be reduced, thereby reducing blockage of the main reflector and increasing the bandwidth of the system. <IMAGE>
