Title: Hazard warning means for road vehicles
Inventor: MOORE ANDREW THOMAS
IPC: G08G1/16
Filed: 1984-11-05
Abstract: A hazard warning system for a road vehicle (10) includes, for causing periodic illumination of the amber warning lights (16-22) of the vehicle, an automatic switch (34) which comprises (a) one or more sensors each responsive to a selected parameter of the vehicle and each operative to produce an output signal whenever the value of that parameter reaches a predetermined 'hazard' level, and (b) a switching means responsive to the production of any such output signal and operative in response thereto to initiate said periodic illumination.   Said parameters may include, for example, the rate of deceleration of the vehicle. Other parameters are also mentioned (e.g. engine (or other) temperature; steering wheel movement; loss of oil; tyre deflation; manual switch). In a modified arrangement, the automatic switch 34 may also activate a radio transmitter, and if desired, an audible tone generator for emitting radio and audible hazard signals respectively. <IMAGE>

Title: Password-protected data link
Inventor: JONES DAVID ROBERT LLEWELLYN
IPC: G06F21/31
Filed: 1984-11-13
Abstract: A password-protected data communication system for transfer of data between remote user terminals and a host computer via public telephone lines and the like is further made secure by virtue of the fact that password transactions and/or interchanges are automatically effected between special modems provided at the user terminals and at the host computer without action or intervention (other than call initiating action) by the users who are denied access to or control over the passwords. A callback facility may also be provided and can be structured to enable users to communicate with the host from non-static locations.

Title: Hall-effect attitude sensors
Inventor: PERSON DAVID LOUIS HALSEY
IPC: G01C9/06
Filed: 1985-11-15
Abstract: An attitude sensor comprises a frame 10 supporting a triangular (preferably isosceles or equilateral) plate pendulum 11 suspended on a shaft 13 adjacent the mid-point of one edge of the pendulum. A Hall- effect integrated switching circuit 19 is mounted adjacent the lowermost point of the pendulum, and a magnet 20 having a pair of equal but opposite poles is attached to the pendulum to act equally on the Hall- effect circuit 19 when in a position symmetrical thereto. A minor disturbance of the pendulum position, e.g. 0.001 DEG gives rise to a significant change in the magnetic flux acting on the circuit 19, so causing the circuit to yield an output indicative of that disturbance. Damping of the pendulum is provided by a helical spring 26 acting through a rigid spring-steel wire 21 wound on a groove 22 on shaft 13, the damping being adjustable by nut 25. it is stated that the magnet 20 and the Hall-effect circuit 19 can be reversed in position, but that this is disadvantageous since electrical connections then have to be made to the pendulum. <IMAGE>

Title: Power supply for gas turbine engine electronic control system
Inventor: RILEY PAUL HOWARD
IPC: H01F30/12
Filed: 1985-12-20
Abstract: The electronic control system (12, 14) of a gas turbine aero engine is powered from windings (25, 28) on the stator (20) of an engine-driven A.C. generator (16). To render the power supply (10) to the control system independent of operation of the engine with minimum complication, the stator (20) of the generator (16) is provided with one or more additional windings (18) which are not connected to the control system but which are connectable by a switch (22) to an independent source of A.C. power, namely the 3-phase power system of the aircraft. When the additional winding (18) is connected to the independent power source and the rotor (24) is not being driven by the engine, the generator (16) acts as a transformer having a 3-phase A.C. power output to the control system (12, 14) through the other stator windings (25-28). <IMAGE>

Patent GB-2180698-A (GB)
Title: Bonding integrated circuit chips to substrates
Inventor: CREMERS DR ROLF A
IPC: H01L21/60
Filed: 1986-09-23
Abstract: A method of conductively attaching a chip to a substrate e.g. a liquid crystal cell includes the step of applying a spot pattern of conductive adhesive to an intermediate carrier. The pattern corresponds to the pattern of the connecting conductors on the chip. Since the intermediate carrier has a low adhesion with the adhesive the adhesive can be transferred to the conductors of the chip by contact and the chip then secured to conducting paths on the substrate. The defined predetermined geometry and the adhesive specification ensures that no short-circuit bridges form. Prior to hardening of the adhesive, a dynamic operational test of the chip can be effected with test-apparatus contacting by way of the conductor paths and if necessary a chip displaying malfunctions can be removed and exchanged. The conductor paths can be produced in thin-film technology and thereby do not represent a restriction for the substrate spacing of liquid-crystal cells which can be produced economically groupwise in a batch process.

Title: Surface-controlled subsurface safety valve
Inventor: VINZANT MICHAEL BURL
IPC: E21B34/10
Filed: 1986-11-12
Abstract: A surface controlled subsurface safety valve for use in a well tubing string includes a valve closure member 35, an operator tube 40 for opening the valve closure member 35 and holding it open, an annular piston on the operator tube 40 operative in response to control fluid pressure conducted from the well surface, a spring 44 biasing the operator tube 40 to a position at which the valve 35 is closed, and a lockout sleeve 50 mounted in tandem with the operator tube 40 for movement simultaneously with the operator tube 40 to a position at which the lockout sleeve 50 holds the valve 31 open. The operator tube 40 and lockout sleeve 50 are engageable by a shifting tool (not shown), to operate the operator tube 40 and lockout sleeve 50 simultaneously. The lockout sleeve 50 can be returned to an inoperative position by control fluid pressure moving the operator tube 40 to a position which opens the valve closure member 35. The safety valve is also operable by a modified shifting tool engaging the operator tube. The shifting tool includes selective keys and separate expandable latch dogs for simultaneous coupling of the operator tube 40 and the lockout sleeve 50. <IMAGE>
Patent GB-2198204-A (GB)
Title: Pipe connection
Inventor: BELCHER BRYAN LESLIE
IPC: F28F9/18
Filed: 1986-12-06
Abstract: A pipe connection between a first pipe (10) and a second pipe (16) in which the first pipe (10) is penetrated by the second pipe (16). The first pipe (10) is provided with an additional wall (12) in the region of its penetration which is also penetrated and which cooperates with the first pipe wall (10) to define a cavity (15) through which an inert fluid flows. Any failure of the seal (20) at the junction between the additional wall (12) and the second pipe (16) results in any fluid within the pipes (10, 16) leaking into the flow of inert fluid, not the environment externally of the pipes (10, 16). In use, e.g. in a heat exchanger, the pressure of the inert fluid is intermediate that of the fluid in the pipes and that of the environment externally of the pipes. <IMAGE>

Title: Relief valve
Inventor: FLETCHER JOHN
IPC: F16K17/10
Filed: 1987-09-15
Abstract: A relief valve comprises a valve closure element (16) biassed towards engagement with a valve seat (18) by fluid pressure in a chamber (31). A conduit (34,38,40,68) extends between the fluid inlet (12) and the chamber (31). A control valve (42) in this conduit responsive to pressure applied to the fluid inlet (12) allows communication between the fluid inlet (12) and the chamber (31) up to a certain value of pressure applied to the fluid inlet, at which pressure the valve (42) isolates the chamber (31) from the pressure in the fluid inlet. As shown, once the chamber (31) is isolated from the fluid inlet (12), the chamber (31) forms a spring whose spring rate is virtually zero, and whose force will not increase as the valve closure element (16) moves. The control valve (42) preferably includes a diaphragm (44) which moves away from a member (62) in the event of excess pressure in chamber (31). <IMAGE>
