Title: Switch
Inventor: HOLLINS WILLIAM JOHN
IPC: G02B6/35
Filed: 1983-05-09
Abstract: A switch comprises a pair of relatively movable switch components 21, 23 and an optical fibre system 15, 17, 22 which defines a light path when the switch is in a closed position and which when the switch is in the open position is prevented from conducting light. There may only be two optical fibres one in each switch component. The switch components may be plastic mouldings, removeable from members to which they are attached such as a door and door frame. Each moulding may have a number of optical fibres defining alternative channels 32, 33. A switch system for a series of fluid flow control valves, each with a stem having a light transmitting window has optical fibres defining a light path from an emitter to a receiver via the windows and arranged so that light can travel only when all the valves are in a predetermined mode. <IMAGE>

Title: Method of impregnating wood
Inventor: DICKINSON DAVID JOHN
IPC: B27K3/32
Filed: 1983-05-25
Abstract: This invention relates to a method of impregnating wood in order to protect it against fungal decay. Conventionally wood has been treated with copper-chromium-arsenic preservatives in a one stage treatment, e.g. by impregnating the wood with a solution of these compounds. The chromium component serves to fix the copper in the wood to prevent it from leaching out. It has now been found that a two- stage treatment in which (1) the copper and fixative agent are impregnated without arsenic and (2) the arsenic is impregnated separately, improves resistance of the wood to soft-rot fungi. The invention is particularly useful for treating hardwoods.

One arm (41) is carried by a resilient tongue (45) biasing the gears into mesh and being movable to permit insertion of the gears. <IMAGE>
Patent GB-2121964-A (GB)
Title: Ultrasonic testing using mode conversion
Inventor: BOND LEONARD JOHN
IPC: G01N29/44
Filed: 1983-06-14
Abstract: In a method of ultrasonic testing pulse inputs are applied via at least two input transducers (10, 11) to a first surface (12) of a test piece (13). The inputs are aimed to overlap one another on meeting a second surface (14). The response to the inputs is sensed by an output transducer (15) and analysed by an oscilloscope (18) or a computer (19) with reference to signals derived from signal generator (16) which energizes the input transducers alternately (10, 11) via a splitter (17). Straightforward time domain analysis of responses yields information about both length and orientation of a defect (20). The input transducers may operate in the shear wave mode, and the output transducer in the compression wave mode by making use of mode conversion at the flow. <IMAGE>

Patent GB-2168761-A (GB)
Title: Fixed choke carburettor
Inventor: ABIDIN ANWAR
IPC: F02M7/12
Filed: 1985-11-18
Abstract: A fixed choke carburettor has a choke valve 4 operated by an electric actuator 5 under the control of an electric control device 6 which processes operating parameters  alpha ,  lambda , n, T, of the carburettor and of an engine to which the carburettor is fitted, fed to it by sensors 3, 24. A main one of these parameters is the opening angle of a main throttle valve 2. The choke valve 4 is coupled by a linkage 6 to a profiled metering needle 17 which is axially movable in a jet 19 to vary the free cross-sectional area of the jet 19 to control the flow of fuel through a duct 10, 11 from a float chamber 20 to a main jet 12 in a mixing chamber 1. As the choke valve 4 is closed, the needle 17 is raised to increase the fuel flow. Rapid opening of the throttle valve 2 causes the control device 6 to close the choke valve 4 to some extent and accordingly the mixture is enriched by the multiplicative effect of the increase of vacuum at the main jet 12 owing to closure of the choke valve and the increase of fuel flow owing to the increase of area at the jet 19. <IMAGE>
