Patent GB-2234059-A (GB)
Title: Solid fuel-effect electric fire
Inventor: FITZPATRICK JAMES
IPC: F24C7/00
Filed: 1990-04-17
Abstract: An electric heater simulating the appearance of a solid fuel fire comprises a plurality of heating elements (R1 - R5) connected in parallel to an A.C. mains supply. In use, the elements would be located in a housing simulating a solid fuel fire and covered with a bank of artificial coals 30. Each element has a triac connected in series therewith, the triacs being controlled by a microprocessor, which thus controls the energy supplied to each of the elements. By controlling the energy supply, individual elements can be selectively driven beyond their rated capacity so as to produce a visible glow through the bank of coals, the supply to the elements being time-multiplexed between the elements in a pseudo-random manner such that individual elements are not run at high temperatures for excessive periods and such that a continuously varying glow is visible through the coals. The fire is also well suited to remote control by means of a hand-held unit. <IMAGE>

Title: Deploying of ammunition
Inventor: MATHEY CHRISTOPH
IPC: F42B10/56
Filed: 1991-06-14
Abstract: When a mine (1) is deployed over the ground, at least with some of the cords 3 from a braking parachute (2) to the mine (1), there is a connection (A) on the mine-side end which is released when righting the mine. An eyelet 13 on the cord 3 is pushed over a pin 10 attached either to the end of the righting element 7 or to the mine housing 9, so that the eyelet is pulled down or pushed down from the pin by the operation of the righting device. In this way the formation of a hollow charge-jet is not disturbed by cord parts lying on the hood 4.   <IMAGE>
Patent GB-2247578-A (GB)
Title: Electric cooker appliance with cooking pan suitability display
Inventor: SHIMOMURA NOBUO
IPC: H05B3/68
Filed: 1991-06-20
Abstract: The appliance includes a halogen lamp type heater 3 and a pan suitability indicating display 17a - 17e controlled by a microcomputer 19 which evaluates the degree of heat absorptivity of the pan in use. A thermostat switch 8 opens when the temperature in the region of the lamps 3 exceeds a predetermined level. Each time switch 8 opens, computer 19 causes the lamps 3 to be operated at a stepped down power level (e.g. decrease of 0.1kw for lamps having a maximum rating of 2kw) when switch 8 recloses. Once power has been decreased to a certain level (e.g. 1.6kw), further openings of switch 8 do not cause any additional decrease. Pan suitability is determined if the maximum power is initially set by user controls 12 to 15, and may be established after a predetermined cooking time (e.g. 10 minutes) in dependence on the power level to which the lamps have been stepped down at that time, or in dependence on the number of times switch 8 has opened. Alternatively, the determination may be made when switch 8 has remained closed for more than a certain time. In both cases the lowest level of pan suitability may be indicated immediately on stepping down to the certain power level (1.6kw). <IMAGE>

The spiked device (15) includes a rigid earth contact (14) and two sprung contacts (16). A counterpart (12) may connect the connector to a pendant fluorescent lamp. The lamp is intended for illuminating building work. <IMAGE>
Patent GB-2250378-A (GB)
Title: Method of forming silicon nitride capacitors
Inventor: GARDNER NEAL F
IPC: H01L27/04
Filed: 1991-09-18
Abstract: A method for fabricating silicon nitride metal-insulator semiconductor capacitors as part of an integrated circuit fabrication is disclosed. In prior art, the fabrication process requires formation of a silicon nitride layer on a pad oxide layer as part of the metal-insulator semiconductor capacitors. Both the thickness of the silicon nitride layer and the pad oxide layer are difficult to control. With the present invention, the thickness of the silicon nitride layer 21 is much more easily controlled and undercutting the layer is avoided since a layer 22 of polysilicon or amorphous silicon is deposited over the dielectric nitride layer before etching to produce the desired pattern but after processing steps are carried out to produce N-type regions 17A, 17B and oxide isolation 13. The silicon layer 22 is then implanted to render it conductive and metallization 20 is applied. The method can be incorporated into the process steps for fabricating an integrated circuit. <IMAGE>

Title: Reducing amplifier distortion by comparison of input and feedback from output
Inventor: PORTER BARRY ELLIOT
IPC: H03F1/34
Filed: 1992-02-13
Abstract: An amplifier circuit comprises a main amplifier (12) having an input (16) for receiving an input signal and an output (18) for delivering an output signal, a first feedback circuit (14) and a second feedback circuit (R1, R2). The first feedback circuit (14) comprises an attenuator (R3, R4,) which attenuates the output signal to the level of the input signal, a phase correction circuit (R8, C2, R9 C3) which compensates the input signal for phase changes occurring in the main amplifier (12) and a difference amplifier (22) which subtracts the attenuated output signal from the phase corrected input signal. The output of the difference amplifier (22) is amplified in an operational amplifier (23) and supplied to the main amplifier (12) as a negative feedback signal. In operation, the first feedback circuit (14) greatly reduces the level of distortion components in the output signal. <IMAGE>

Title: Liquid meter
Inventor: HOWKINS KENNETH JOHN
IPC: A01G25/16
Filed: 1992-11-27
Abstract: In a liquid meter, e.g. for metering water supplied through a hosepipe to a garden sprinkler. water flows through an inlet 14 via a nozzle 20 to an outlet 15 striking the paddles 21 of a paddle wheel 22 on the way. The paddle wheel forms the start of a train of reduction gears 22, 23, 30, 31 33, 34 and 36. The final gear 36 has a pin 47 which holds a pivoted crank 43 in position, so holding the gate 40 of a gate valve open against a spring 42. As gear 36 turns anticlockwise, pin 47 turns crank 43 clockwise, lifting its end 45 away from gate 40 and so releasing that gate to slide down between guides 41 and so turn off the water flow. The device may be preset by setting the angular position of gear 36. <IMAGE>

Title: Optical amplifier
Inventor: TANIKAWA KAZUYUKI
IPC: H04B10/077
Filed: 1994-02-10
Abstract: An optical amplifier incorporates a doped fibre loop 10 pumped by a laser diode 81 or 82. The amplifier is controlled by a feedback loop 3, 4, 71 or 72, 101 or 102 providing an oscillatory signal to the laser diode. Conventionally the fed back signal has a sinusoidal component which is used for control purposes, but if the laser diode 81 or 82 becomes saturated due to temperature or aging effects, this signal is inappropriate. The invention modifies the feedback signal when saturation occurs, for example by removing positive excursions (fig 2b) or by emphasizing the positive excursions (fig 2a). <IMAGE>
