Patent GB-2207799-A (GB)
Title: Tuneable lasers
Inventor: GRATZE STEPHEN CECIL
IPC: H01S3/106
Filed: 1987-08-04
Abstract: A tuneable laser having a range of possible emission frequencies has a Bragg cell 9 mounted inside its laser cavity 1 such that only light passing through the Bragg cell without Bragg deflection will be emitted by the laser. The Bragg cell may be supplied with broadband noise 14 via a notch filter 15, the frequency of the notch defining the frequency of light which passes through the Bragg cell without Bragg deflection, other frequencies of light being Bragg deflected into light absorbent walls 7 and 8. The frequency removed by the notch filter can be selected by computer 17 and laser frequency can be altered from pulse to pulse. Instead of broadband noise a number of frequencies may be fed to the Bragg cell so that laser light at frequencies other than a selected frequency undergoes Bragg diffraction. <IMAGE>

Title: Protected electrical supply arrangement
Inventor: SMITH EDWARD
IPC: H02H3/14
Filed: 1987-11-06
Abstract: A protective arrangement for trailing electrical sockets 13 has a voltage discriminator 20 which monitors the voltage between the earth and neutral conductors. If this rises above a threshold value, it trips an electronic crow-bar switch 21, which then provides a low impedance path between live and neutral, blowing a fuse in the live conductor. The invention protects against the hazard of high leakage currents, accumulated from several items of equipment. Alternatively, the switch 21 may be replaced by an audible warning device. <IMAGE>

IPC: F16K31/06
Filed: 1988-02-12
Abstract: A valve has within a chamber (11) a disc-shaped armature (8) mounted freely movably axially and with a centrally arranged sealing member (9). The armature (8) is moved axially by means of an electromagnetic field which can be induced by an exciting winding (19), whereupon the sealing member (9) is pressed against a sealing seat (3) at the end of a straight tubular portion (1) which is made of non-magnetic material. On its free end this tubular portion (1) has a connecting socket (2) for connection to a pipeline. The tubular portion (1) also passes through the exciting winding (19) so that the axes of the tubular portion (1) and the magnetic field lie parallel to one another. A preferably conical coil spring (12) acts against the armature (8) and tubular portion (1). At least one projection is provided inside the chamber (11), which extends towards the armature (8) and limits the travel of the axially movable armature (8). The valve housing, which bounds the chamber (11), only has one weld seam (17) and is attached to the casing (20) of the winding (19) by a cap which surrounds the valve housing and is screw-threaded at (22) onto the casing (20). <IMAGE>

Title: Drill string circulating valve
Inventor: HALLAM PETER JOHN
IPC: E21B21/10
Filed: 1989-02-03
Abstract: A circulating sub for a drill string has inner (16) and outer (18) coaxial subs between which a cylindrical sleeve (20) is coaxially slidable. The sleeve is retained in a first position by sheer pins (22) to close aligned ports (26, 24) in the subs (16, 18). If, for any reason, fluid pressure outside the outer sub drops below a pre-selected value the pressure differential across a piston flange (28) of the sleeve (20) rises to a level sufficient to sheer the pins (22) forcing the sleeve down and opening the ports (24, 26) to allow greater flow of fluid into the drill hole. <IMAGE>

Title: Processor suitable for recursive computations
Inventor: KNOWLES SIMON CHRISTIAN
IPC: G06F7/483
Filed: 1990-09-26
Abstract: A processor suitable for recursive computations incorporates multiplier cells (16) connected to form rows (12) and columns (14). Each row (12) is arranged to multiply by a coefficient. It begins with accumulator cells (18 and 20), and continues with multiplier cells (16) arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Columns (14) other than the first column (141) begin with a multiplier cell (16), and the higher significance columns (141 to 144) terminate at respective accumulator cells (20). Any intervening multiplier cells (16) are arranged in ascending order of multiplier digit significance. The multiplier and accumulator cells (16 to 20) operate in accordance with signed digit number representation arithmetic involving digit redundancy. They generate sum and transfer digits for output down columns (14) and along rows (12) respectively to neighbouring cells, in the direction of increasing digit significance in the case of transfer digits. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digit is recycled when formed to provide a multiplicand digit input for all multiplier cells (16) of a respective row (12) selected in accordance with result digit significance. The processor (10) is also arranged to add successive non-recursive input terms to multiplier products. This provides for the processor (10) to provide a first order infinite impulse response (IIR) filter section, and two cascaded processors (50, 50') provide a second order IIR filter section. <IMAGE>

Title: Press with positioning motor
Inventor: KACZMAREK DAVID
IPC: B30B15/14
Filed: 1991-07-30
Abstract: Material is worked in a press which has a positioning motor 17 for driving a movable tool 25. The motor is energised only when the tool is required to be moved. Kinetic energy is not stored in the press when the tool is not moving. The positioning motor enables the crankshaft 19 and hence the tool 25 to be brought to rest at any predetermined position and also enables the tool to be moved in small increments towards and away from a bottom tool 26. After the power stroke the motor 17 is used to brake the moving parts. Electrical energy generated by the motor during braking may be used to drive material feeding means. The motor may be microprocessor controlled. Energy is used more efficiently to work the material and there is no need for a conventional flywheel, clutch and brake. <IMAGE>

Title: Metering and dispensing system
Inventor: WHITE THOMAS HENRY
IPC: G01F1/00
Filed: 1991-08-21
Abstract: A metering system for liquids which is particularly adapted for accurately controlling small flows of liquid. A pair of metering tubes (3, 10) which are alternately filled and emptied are each provided with level sensors (9, 4; 19, 18) providing input signals to a control circuit. This determines the actual flow rate from the current tube and is also supplied with a set input of a desired flow rate, from which a dispensing pressure signal is determined and applied to an electropneumatic transducer so that corresponding dispensing pressure is applied to the liquid. The control circuit also stores the current value of dispensing pressure which is utilised in the determination of the dispensing pressure at the next dispensing cycle. <IMAGE>
