Patent GB-2256603-A (GB)
Title: Operation of an internal combustion engine
Inventor: MA THOMAS TSOI-HEI
IPC: F01N13/02
Filed: 1991-10-11
Abstract: A method is described of operating an internal combustion engine burning a fuel containing carbon and hydrogen, such as petrol, diesel fuel or alcohol, and having a catalytic converter 10a, 10b arranged in the exhaust system at a distance from the engine and an afterburner 16 and igniter 18 upstream of the catalytic converter to assist in lighting-off the converter. An excess of fuel is introduced to the engine at starting; this ensures the presence of hydrogen in the exhaust. Oxygen is either present in the exhaust or added via pump 30. This inflammable mixture is ignited by means 18 and heats the converter. Afterwards, either the excess fuel or the added air is regulated to give a less flammable mixture which either gives stable combustion or catalytic reaction. <IMAGE>

Title: Ladder wedge
Inventor: NEWMAN RICHARD LESLIE
IPC: E06C7/44
Filed: 1991-10-21
Abstract: A ladder wedge comprises a flat base (2) having a sloping upper surface (3) carrying a central channel (6) adapted to receive a ladder leg. Stop means, adapted to block the channel, restricts any downward movement of the leg. The stop means preferably comprises a rigid plate and the sides of the channel carry a series of slots (7) adapted to receive the edges of the plate; the slots may be extended into the base of the channel.

In use one leg of a ladder is placed on the surface of sloping ground and the other in the channel. The leg in the channel is moved until the ladder is vertical. The stop is placed in an appropriate pair of slots to retain the leg. The stop means can take the form of frame with a central portion displaced from the frame, preferably by a quarter of the distance between the slots. <IMAGE>

Title: Starter for a fluorescent lamp
Inventor: MUELLER SIGBERT
IPC: H05B41/08
Filed: 1992-03-31
Abstract: The starter contains a glow igniter 6, a resettable bimetallic switch 7 and an NTG resister 8 which are connected to one another in series. Parallel to the NTC resister 8 lies an ohmic resister 9 which is of considerably lower resistance than resister 8 in the temperature range of minus 20 DEG C to +80 DEG C and which ensures a fast preheating of the electrode coils of the lamp.

Title: Alignment of wafers in printing
Inventor: PENN RANDY JOHN
IPC: H01L21/68
Filed: 1993-08-27
Abstract: Detrimental buildup of tramp photoresist material upon the positioning pads of a stage plate 35 for wafer printing machines is prevented by providing an arcuate point contact surface upon the positioning pads. The wafer is supported a predetermined focal length from the photoresist light curing source by said point contact support.

Title: Liquid/liquid separation
Inventor: WELCH THOMAS C
IPC: F02M37/54
Filed: 1993-11-09
Abstract: A first liquid which is immiscible and forms a discontinuous phase with a second, continuous phase-forming liquid, is separated therefrom by feeding the liquid mixture from inlet 14 to at least one coalescing assembly 22 which coalesces the first liquid, and then allowing the second liquid to pass through at least one separating assembly 30 to outlet 24, the assembly 30 repelling the first liquid droplets which are discharged by outlet 34. As shown assemblies 22 and 30 comprise tubular, radial flow filters and are vertically stacked, with either assembly uppermost depending on whether the discontinuous phase is the heavier or lighter. The numbers of filters in respective assemblies may differ, e.g. two or more coalescing filters may be stacked on top of a single separating filter or alternate coalescing and separating filters may form one stack. Coalescing filters may comprise a packing of polyester or polybutylene teraphthalate fibres. Separating filters may comprise a web of PTFE fibres bonded by fluorinated ethylene propylene. <IMAGE>
