Patent GB-2122859-A (GB)
Title: Improvements in or relating to microwave heating
Inventor: HARDWICK WILLIAM HORTON
IPC: B01J19/12
Filed: 1983-07-05
Abstract: The invention is concerned with microwave heating and more particularly with microwave heating to effect melting. Material is contained in a container (1) and microwave energy is applied to met material (6) while a portion of the material (7) adjacent to the internal surfaces of the container is maintained at a temperature at which it is not molten. This may be by cooling water (5) in vessel (4). The invention therefore provides for "skull" melting in which a layer of non-molten material protects the container from molten material. Examples of materials which may be treated in accordance with the present invention are glasses and glass-like materials and precursors therefor (e.g. glasses and glass-like materials or precursors therefor containing radioactive wastes). <IMAGE>

Title: Television receiver load compensation circuit
Inventor: HAFERL PETER EDUARD
IPC: H04N3/18
Filed: 1984-06-28
Abstract: A deflection circuit (39) is coupled to a horizontal deflection winding (Ly) for generating scanning current in the winding. A retrace pulse voltage is developed across the deflection winding (Ly) during the retrace interval. A flyback transformer (T1) is coupled to the deflection circuit (39) and has retrace pulse voltages developed across windings thereof. A source (19) of supply energy is coupled to a first winding (W1) of the flyback transformer (T1) and a load circuit, such as a high power audio circuit (36), is coupled to a second winding (W4) of the transformer and draws load current therefrom. A switched mode power supply (S1,S2) is coupled to the source (19) of supply energy and to the flyback transformer (T1) for controlling the transfer of energy between the source (19) and the load circuit (36). A compensation circuit (30) responsive to the operation of the switched mode power supply produces variations in current in an inductance (L2) coupled to the flyback transformer (T1). These variations are indicative of variations in load current drawn by the load circuit (36). The flyback transformer (T1) couples the inductance (L2) to the retrace resonant circuit (Cr) for a variable amount of time during retrace to control the transformer trace-retrace duty cycle in a manner that compensates for retrace time modulation due to loading variations. <IMAGE>

Patent GB-2176028-A (GB)
Title: Fuel injection apparatus
Inventor: OSHIZAWA HIDEKAZU
IPC: F02D41/20
Filed: 1986-05-22
Abstract: In a fuel injection pump which is capable of adjusting the fuel injection quantity by the ON/OFF control of a solenoid valve 7, the solenoid is driven by a first pulse in response to an injection timing signal and by a subsequent second pulse whose duration depends upon the desired fuel quantity. The second pulse is administered when it is detected that the valve has responded to the first pulse. Such control is accurate since it accounts for the delay in operation of the valve in response to the first pulse. <IMAGE>

Patent GB-2203616-A (GB)
Title: Improvements in or relating to data communication systems
Inventor: BRYANT STEWART F
IPC: G06F13/28
Filed: 1987-04-01
Abstract: Incoming data which is required to be passed to a desired storage location under the control of a processor is received by a store prior to being passed to a serial communications controller. The store is preferably a FIFO store and stores the data at an incoming data rate determined by the incoming transmission line data rate and feeds the data to the serial communications controller at a higher data rate under the control of a clock generator which is energised by control circuitry only when the data may be accepted by the serial communications controller. The processor can therefore control the serial communications controller to cease to process incoming data, which data is then stored until the processor can spare the time to recommence processing the incoming data.

Title: Decorticating machine
Inventor: TAINSH JOHN ARCHIBALD RAMSAY
IPC: B02B3/04
Filed: 1988-06-14
Abstract: In a mill specifically for grinding off the inedible hard cortex of the Winged Bean (PSOPHOCARPUS TETRAGONOLOBOUS) with minimum damage to the nutritious endosperm, grinding is performed by gravitating the beans repeatedly through an adjustable gap between a pair of abrasive coated horizontal axis drums A/1, A/2, which rotate at different speeds in opposite directions, downwards at the grinding gap. The drums are mounted in a container fed at one end (R, Fig 2 not shown) with raw beans. Partly cylindrical guide-sheets H/1, H/2 around the bottoms of the drums repeatedly force the beans being processed up to the tops of the drums to fall into the gap again, as they flow in spirals round the drums towards the overflow (S, Fig. 2). The cortex particles are separated from the endosperms by screening and aspiration. <IMAGE>
