Patent GB-2156147-A (GB)
Title: Discharge lamp assembly and method of manufacture
Inventor: IWAI IKUO
IPC: H01J61/36
Filed: 1985-02-28
Abstract: The ceramic envelope 21 of a high pressure sodium lamp has integrally moulded end walls 21a, 21b with respective throughholes 22a, 22b in which are sealed electrode lead-in conductors 23a, 23b by means of annular plates 26a, 26b fixed on the outer surface of each tube end wall by an adhesive agent 27a, 27b which fills the gap between the annular plate and the tube end wall but which only partially fills the gap between the throughhole and the lead-in conductor so that the inner end of the adhesive stops short of the inner surface of the tube end wall. By this means reaction between the sodium of the lamp filling and the adhesive agent is prevented, thus reducing sodium loss. In manufacture, the adhesive disc and the annular plate may be placed around the lead-in conductor in any order. <IMAGE>

Title: A method of controlling a distribution of carrier lifetimes within a semiconductor material
Inventor: FRITH PETER JOHN
IPC: H01L21/324
Filed: 1985-08-23

Patent GB-2165500-A (GB)
Title: Vehicle with air suspension
Inventor: DAVIS ROBERT CLIVE BROWNING
IPC: B62D61/12
Filed: 1985-10-11
Abstract: Trailer vehicles fitted with two or more axles provided with air suspension frequently have provision for lifting one axle together with its associated wheels to reduce rolling resistance and tyre scrub when the trailer is running lightly laden. Such vehicles are usually fitted with a levelling valve operated by rise or fall of one axle to admit pressure air to or release it from the air springs to maintain a constant ride height. The tyres on a lifted axle lose their deflection when load is removed from them, reducing their clearance from the road surface. An extensible member 49 is provided in the operating linkage for levelling valve 47. Extension of member 49 as or when an axle is lifted causes operation of valve 47 to admit pressure air to the air springs of the laden axle(s). These springs extend and in so doing neutralise valve 47 so that trailer then runs at an increased ride height. <IMAGE>

Patent GB-2186459-A (GB)
Title: Optical actuator
Inventor: JONES ROGER EDWARD
IPC: F16K31/00
Filed: 1986-02-12
Abstract: An arrangement for remotely operating a valve (1), uses optical power, e.g. from a high-power laser, which is passed via an optical fibre (8) to a copper capsule (7), the end face of which is blackened to assist heat absorption. The capsule is filled with wax and also contains copper mesh in good heat conductive relation with the end face of the capsule (7). When the valve is to be operated, optical power from the fibre (8) is absorbed by the capsule's end face. Hence the wax is heated and expands to move a push rod (9), which via the linkage shown opens the valve against a spring (2). To reset the valve the optical power is cut off, the wax cools and contracts and the push rod (9) returns to rest, so that the spring (2) closes the valve. <IMAGE>

Title: Organic emulsions for electrodepositing polymeric alloys and copolymers
Inventor: ALVINO WILLIAM MICHAEL
IPC: C08J3/09
Filed: 1986-07-11
Abstract: Organic emulsions have a discontinuous phase which comprises at least two compounds of different structural formula selected from solvent-soluble polymers, oligomers, and monomers dissolved in an organic solvent, and continuous phase which comprises an organic non-solvent for the compounds. The emulsions can be used to coat a conductor (e.g. graphite in the form of a cloth) by immersing the conductor in the emulsion and applying a direct current between the conductor and another electrode so as to cause the discontinuous phase of the emulsion to migrate to the conductor and deposit on it. The conductor is removed from the emulsion and dried, and the deposit is cured if necessary (e.g. if the deposit includes oligomer or monomer).

Title: Intruder detection apparatus
Inventor: SCHOFIELD ROY ALAN
IPC: G08B13/24
Filed: 1989-04-10
Abstract: Known intruder detection apparatus utilising a microwave transmitter (not shown) lined-up with a receiver antenna 12 monitors the signal for any variation thereof. Output from the antenna 12 is processed by microwave detector 14, AC amplifier 16 and processing circuitry 18 to provide a DC output proportional to the change in signal strength. An alarm relay 22 is actuated when the DC output exceeds an alarm threshold value stored in detector/comparator 20. In order to distinguish signal variations caused by natural phenomena, such as long grass etc, an additional detection channel 24 is provided including a resistor/capacitor (R-C) circuit 32, 34, 36, 38 which effectively requires the signal change to exceed the maintenance threshold set by a second detector/comparator 26 and lower than the alarm threshold for a predetermined timed period which will be chosen as considerably greater then the longest period necessary for an intruder to pass between the transmitter and the antenna 12. Activation of the maintainance alarm 28, may signal grass cutting needed, or may cause automatic increase in the alarm threshold. <IMAGE>
