Patent GB-2159360-A (GB)
Title: Power supplies
Inventor: PIASKOWSKI ANDREW DIONIZY
IPC: H02M1/42
Filed: 1985-06-25
Abstract: A power supply circuit comprises first and second SCRs (8,9) operative to pass a cyclically reversing current through a load circuit (17,1,2) from a d.c. supply (Vs). The SCRs are turned on alternately by a circuit comprising a first transformer (36P,36S) having a primary winding section (39) through which free wheel current passes during commutation of the first SCR (8), and a secondary winding (36S) coupled to the gate of the second SCR (9) so that cessation of the free wheel current through the primary winding section (39) of the first transformer induces a signal in the secondary winding (365) for firing the second SCR (9). A second transformer (27P,27S) has a primary winding section (59) through which free wheel current passes during commutation of the second SCR (9), and a secondary winding (275) coupled to the gate of the first SCR (8) so that cessation of the free wheel current through the primary winding section (59) of the second transformer induces a signal in the secondary winding (27S) for firing the first SCR. This configuration ensures that switching of the SCRs takes place in a zero current condition, so that generation of interference is greatly reduced. <IMAGE>

Title: Optic-waveguide biosensor
Inventor: STEWART WILLIAM JAMES
IPC: G01N21/75
Filed: 1986-04-07
Abstract: An optic-waveguide biosensor (fig 2) of the type comprising an optic-waveguide (1) provided with a coating (7) sensitized to a specific assay species, and input and output coupling members (3) and (5). Light signal response is enhanced by incorporating a partially reflecting, partially transmitting, low refractive index medium (15) between each coupling member (3,5) and the waveguide (1). The thickness of this medium (15) is chosen so that light may be coupled by frustrated total internal reflection and so that the medium (15) serves as a resonant mirror. It may be in the form of a single layer (fig 3(a)) formed of eg. magnesium fluoride or alumina material. Alternatively, it may be of multilayer structure dielectric material (fig 3 (b)).

Patent GB-2192479-A (GB)
Title: Braille read-out
Inventor: GLAZER JULIEN
IPC: G09B21/00
Filed: 1986-07-10
Abstract: A Braille read-out for transliterating computer derived information comprises a line of modules 12. Each module 12 contains sets of character defining pins 15 which are arranged into cells 14, a cell being actuated by a single, movable actuating assembly 18 which travels along the line of modules 12 powered by a stepper motor 21. The actuating assembly 18 consists of a group of pin solenoids 23, each one corresponding to a pin 15 in a cell. To erase a character from the set of pins a latching plate 26 associated with a set of pins is moved from an engaged position in which the pins are prevented from movement, to a disengaged position the pins fall back into the body of the module 12. By this, characters may be erased and set in each cell in turn. A cell does not require a dedicated actuating assembly, thus less space is consumed per cell. The latching plates 26, being operated individually, allow new characters to be set in the cells without having to wait until the reader finishes a complete line of text. <IMAGE>

Title: Rotary I.C. engine
Inventor: MCDONALD KENNETH
IPC: F02C5/04
Filed: 1986-08-30
Abstract: A shaft 1 supported by bearings 32 in oil sumps 4 is driven by a rotor 14. Air is driven by a turbine 7 through a nacelle 8 where petrol is introduced at 9 into the airstream and the mixture passes through inner induction chamber wall inlet port 10 and rotor inlet port 28 into combustion chamber 24 in the rotor. As the rotor turns, pistons 13 running in a channel 12 isolate the chamber. When electrode 17 passes through anode 33, points 26 are interrupted by eccentric 15 to provide the ignition spark from coil 27. The outlet port 19 of the rotor now comes into line with the exhaust chamber outlet ports 21 allowing discharge from the combustion chamber to drive the rotor, the spent exhaust gasses escaping from the exhaust chamber 22 through exhaust port 34. <IMAGE>

Title: Wind-driven power plants
Inventor: ADIMORA ANTHONY NGORNADI
IPC: F03D1/00
Filed: 1989-07-29
Abstract: In contrast to a normal windmill in which the blades are substantially flat against the wind at a slight angle so that wind impacting on the blades will transfer wind kinetic energy to the blades to rotate the windmill rotor, in this invention the blades are placed at the same angle as the wings of aircraft. If natural or artificial wind, even at low velocity is blown over the blades, the static atmosphere pressure over the blades drops and the blades are pushed from under by the excess atmospheric pressure which can now turn the windmill rotor to do work or produce electric power. It is stated that the system's power output is theoretically infinite and that it is atmospheric pressure potential energy that is the system's power source, the blades acting as pressure de-equalisers to enable the extraction of this energy. <IMAGE>

Title: Improvements in fluid valves
Inventor: VOSS RICHARD
IPC: F16K15/02
Filed: 1989-09-28
Abstract: A self-sealing valve (1) constructed, in particular, as a non-return valve has a sealing piston (10) which is displaceable in a bore (3) of a housing (2). A spring (17) urges a sealing face (11) of an end portion (12) of the piston (10) against a sealing face (9) of a seating (6) in the housing (2). To render the valve reliable and self sealing the piston is flexible to a limited extent in the region of the sealing face corresponding to the valve seating. To achieve this the end portion (12) of the piston is provided with a plastics coating or consists entirely of plastics material. When this flexible material is pressed onto the valve seating by the compression spring it is deformed and ensures a perfect seal. <IMAGE>
