Patent GB-2261929-A (GB)
Title: Gearing for transmitting rotary motion
Inventor: SNELL LEONARD STANLEY
IPC: F02K1/15
Filed: 1981-10-02
Abstract: The gearing is transmitting rotary motion between a shaft 25 and a ring 30 supported respectively on a gas turbine engine casing 11 and on a curved jet pipe 12 rotatable relative to the casing. The free end of the pipe has a variable area nozzle operable by rotation of the ring 30 relative to the pipe 12. The pipe is rotatable by the shaft 25 acting directly on the pipe 12 through a chain drive 26, 27, 28. Simultaneously, the shaft acts through epicyclic gearing 20, 21, 22 to rotate the ring 30 so that the pipe and the ring rotate together and the nozzle is unaffected by the rotation of the pipe. The nozzle itself is operable independently of the pipe by an actuator 33 via a lever 31 connected to rotate a carrier 23 on which the intermediate gear 21 of the epicyclic gearing is supported. <IMAGE>

Title: Deforming the ends of tubes electromagnetically
IPC: B21D26/14
Filed: 1981-10-15
Abstract: The tube end 1 is located around an induction coil 9 and within a die means 6, with the interposition of a reinforcing element 8. The coil 9 may be energised to effect deformation of the tube end 1 and the reinforcing element 8 simultaneously or consecutively, the electromagnetic force being of repulsion. However, the die means and the coil may be transposed and an attraction force may be used. <IMAGE>
Patent GB-2120869-A (GB)
Title: Controlling the output level of an electrical power supply
Inventor: BEDARD JAMES FREDERICK
IPC: H05B41/39
Filed: 1982-05-04
Abstract: The output level of a load (12) is varied by controlling the proportion of time, during an arbitrary time interval, when the output is energized, thus controlling the average output level of the load. The zero crossings of an AC energizing source waveform (11) are detected (30, Fig. 2) to trigger an interval timer (28, Fig 2a) producing pulses which are coupled to an on/off input (line B) of the load; the duration of each "on" time interval is adjustable (by resistor 28', Fig 2a) to control the portion of the arbitrary time interval during which the load is "on". In the embodiment a discharge lamp (12) driven by an inverter (not shown) is the load. Pulses on line B saturate Q20 to interrupt inverter operation. Inverter frequency and hence maximum light output may be controlled by a variable resistor connected between terminals AA'. A photoisolator (Fig 2) is used to couple pulses from the timing means to line B. An astable multivibrator (Fig 2d) is used to supply all timing information when the inverter is supplied from a continuous DC source, e.g. a battery. <IMAGE>

Title: Fireguard and support bracket therefor
Inventor: SWARTZ LEONARD BERLE
IPC: F24C15/36
Filed: 1982-05-19
Abstract: A support bracket (4) for a fireguard (2) comprises a strut (10) with arms (8) attached thereto. Flat portions (12) are provided at the end of each arm to accommodate a foot or castor (14) of a room heater or the like (6). The feet (14) are retained on the flat portions (12) and the heater is thereby immobilised, and at the same time the fireguard is securely held so that it will not move relative to the heater. The position of the flat portions (12) of the arms can be moved both parallel to and transversely to the struts (10), which are secured to lower edges of the sidewalls of the fireguard. In an alternative embodiment, the arms (8) are bolted directly to the fireguard. <IMAGE>

Title: Corrosion Protection Method
IPC: C09K8/54
Filed: 1982-05-20
Abstract: Embrittlement of metal substrates in corrosive environments, such as gas and oil pipelines, caused by absorption of the hydrogen atoms cathodically evolved during various corrosion processes is substantially prevented by providing an active substance in the vicinity of the metal substrate, and in electrical contact therewith, the active substance being a sulphide or mixed sulphide of a metal of Group Vb, VIb or VIIb of the Periodic Table or of a rare earth metal, especially WS2 and MoS2. The active substance is preferably applied as or in a coating on the surface of the substrate, with an overcoating of, for example, a thermosetting resin, preferably being employed for mechanical and environmental protection.

Title: Developing electrostatic latent images
Inventor: YAMASHITA KEITARO
IPC: G03G15/09
Filed: 1982-05-27
Abstract: Image development apparatus comprises a magnetic brush developer roll (3) consisting of a co-rotating shell (31) and cylindrical magnet (32) with a non-magnetic guide plate (7) positioned over and spaced from a part of the periphery of the developer roll away from the development region W. A toner transporting roll (2), having fixed magnets (21), conveys toner from a sump in the bottom of vessel (1) to the exterior of the guide plate where the toner is attracted onto the outside of the plate to be metered at a controlled rate onto the surface of the shell (31) round a tip (73) of the plate. A scraper blade (71) having openings (72) removes the toner from the shell (31) after development but allows some of that toner to pass between the shell and the guide plate. A doctor blade (74) controls the height of toner on the roll (2). <IMAGE>

Patent GB-2137407-A (GB)
Title: Low pressure discharge lamps
Inventor: KIRBY MICHAEL WILFRED
IPC: H01J61/74
Filed: 1983-03-24
Abstract: A low pressure sodium discharge lamp has a U-shaped tube in an outer envelope (11). The lamp's cool spot tends to be at the bend of the U since the straight leg portions (30, 31) are mutually self-heating. The temperature at the bend can be too low for optimum efficiency and to increase the cool spot temperature the lamp includes a heat shield (47) within the outer envelope reflecting heat from the tube back to the bend. The heat shield is preferably an aluminised disc resiliently supported on the outer envelope. <IMAGE>

Title: Internal sacrificial anode for subsurface conduit
Inventor: HUGHES JERRY DONALD
IPC: F16L58/00
Filed: 1984-02-17
Abstract: A sacrificial anode (12, 58 a-d) is disposed within a length of metal conduit 14 (e.g. well casing or tubing) and in electrical connection therewith, such sacrificial anode constructed of a metal (e.g. Zn, Al, Mg) more active in the Galvanic series than the metal in the conduit, such that as an electrolytic fluid flows through the conduit, a galvanic cell is formed having the protected structure as the cathode.

Title: A regulating circuit for a magnetic hover vehicle
Inventor: BOHN DR GERHARD
IPC: B60L13/06
Filed: 1986-01-03
Abstract: To achieve stable hovering of the magnetic hover vehicle at a standstill it is proposed to provide for each supporting magnet, i.e. each magnetic wheel, an adaptive rail observer 20 which, upon resonating of the rail, is adapted in phase  phi  and amplitude A to the oscillation thereof. The regulating circuit 2 which controls the hovering support magnets is modulated by the time derivative h, ascertained from this adaptation, of the railroad coordinate h. The model of the rail observer 20 is a resiliently-suspended damped mass which is excited by the magnetic force F. Thus oscillation (resonating) of the rail is reduced and hovering stability improved. <IMAGE>
