Patent GB-2104143-A (GB)
Title: Cylinder lock and key
Inventor: DUNPHY GERALD FRANCIS
IPC: E05B29/00
Filed: 1982-07-28
Abstract: A cylinder lock has a plurality of discs (2) forming part of the barrel assembly (1) and rotatable relative to one another and to the body of the barrel assembly. The rotational axis of each disc is substantially coincident with the rotational axis of the complete barrel assembly and each disc has a keyway forming opening (3) which contains that axis. Locking means (4) holds the barrel assembly against rotation relative to the lock cylinder, unless the correct key has aligned the discs in their proper relative positions. In one embodiment each disc (2) carries a ball (28) trapped in its periphery, when the balls are aligned the end ball (28a) projects rearwardly further then normal and moves ball (31) accordingly, thus lifting locking plunger (22) out of barrel recess (26) and permitting rotation (see Fig. 2). In another embodiment (Fig. 41) the locking means is a bar (873) which can enter aligned peripheral apertures in discs (802) to permit rotor (11) to turn relative to stator (811). Each embodiment uses a key such as Fig. 13, wherein indexing surfaces (35) are provided to rotate discs and camming surfaces (43) assist in insertion and withdrawal. <IMAGE>

Patent GB-2144848-A (GB)
Title: Electrical signal spectrum analyser
Inventor: FRENCH HERBERT ALAN
IPC: G01R23/17
Filed: 1983-08-12
Abstract: An electrical signal analyser comprises an acousto-optic cell 15 placed on the path of an input light beam 14 which produces a phase delay which varies across the width of the cell. A lens 21 then provides a Fourier Transform (FT) of the cell phase function in the FT plane 22 where a detector is placed to receive light transmitted through a slit 34 in an opaque screen. A periodic frequency modulated control signal C(t) modulated by an unknown electrical Signal S(t) is used to introduce acoustic waves in the cell 15 by driving a transducer 16 attached to the cell. The electrical signal S(t) can then be determined from the output of the detector 24. Phase information in the electrical signal can be determined by splitting the input light beam 14 to produce a second beam and directing the second beam to impinge on the FT plane 22 at an angle thereby producing a phase gradient across the FT plane. Two detectors placed behind respective adjacent slits can then provide phase information. <IMAGE>

Title: Adding extra air to I.C. engine intake manifold
Inventor: HUAI-CHIH KAO
IPC: F02M29/04
Filed: 1985-07-03
Abstract: Extra air is supplied to an intake manifold 16 via a valve 10 controlled by two diaphragm actuators 7, 8 responsive respectively to pressure in the manifold and at a point which at least some of the time is upstream of a throttle valve. The valve 10 may have a valve member and valve body acted on by the respective actuators or the actuators may act in tandem on the valve member (Fig. 13). The extra air may be taken from upstream of a throttle valve or drawn in through a filter 37, Fig. 15. In the former case the air may be drawn through a pipe 5 in a plate installed between two portions of a carburettor or a pipe 25 in a plate 24 installed downstream of a carburettor.
