Patent GB-1258769-A (GB)
IPC: G02F1/29
Filed: 1969-03-28
Abstract: 1,258,769. Deflecting light. HONEYWELL Inc. 28 March, 1969 [29 March, 1968], No. 16317/69. Heading H4F. A light deflector comprises a transparent body having within its volume at least one group of four mutually adjacent zones which lie in pairs on four planes bounding the group, the zones being distinguished from one another physically, or crystallographically, or by selective electroding of the body, the body consisting in a number of the zones, of electro-optic material and having electrodes so applied thereto that the refractive index of the, or each, electrooptic zone charges on application of an electric field with respect to the refractive index on an adjacent zone on a common boundary plane therewith and light reflective means so located that a light beam entering the group of zones passes at least once between zones which have different refractive indices when an electric field is applied before leaving the group of zones either deflected or undeflected depending on whether or not a potential is applied to the electrodes. As shown in Fig. 1, the body 10 is formed of cubic zones 11-14 and is provided with a reflective coating 19 on a face 16. The body may be a single electro-optic crystal, with shaped electrodes applied, e.g. to produce a field in zones 11 and 13 only, or to produce alternately opposed fields in all the zones, the latter case giving a linear relation between the light beam deflection angle and the applied electric field for materials with a quadratic electro-optic effect. Alternatively the zones may be discrete portions of the same material with the C axes of adjacent zones oppositely orientated and normal to the plane of Fig. 1, and single electrodes are then provided to cover the two square faces of the body 10. In alternative embodiments, the face 17 or faces 17 and 18 may be reflective so that light leaves from face 18 or 15, respectively, Figs. 3 and 4 (not shown). In the latter case, a slightly tilted mirror redirects emergent light back close to its original path through the body. To prevent refraction at the surfaces of the body 10, the surfaces may be surrounded by solid or liquid material having the same refractive index as the material of the body. For the embodiment of Fig. 4, having three reflecting surfaces, a 45 degree right triangular prism may be placed with its longer side against the face 15, Fig. 5 (not shown). Alternatively, the portions 11 and 12 may themselves include portions effectively forming the prism, Fig. 6 (not shown). A plurality of cubic bodies 10 may be joined to form a cuboid, having three faces rendered reflective, to achieve greater beam deflection, Fig. 7 (not shown). In any embodiment, reflection of light through the body may be brought about by using a reflective surface coating, or a suitably placed mirror, or by using total internal reflection by surrounding the appropriate surface with material having an appropriate refractive index.

The cutter head may have cutters 11 adapted to cut in both directions of movement or alternatively in only one direction and may make repeated cuts till the flaws have been removed; alternatively the flaw detecting means may provide an indication of the depth of cut required to remove the flaw and sufficient increment of cut is then applied to finish the workpiece in a second cutting operation. The flaw-detecting means may control the traverse movement of the carriage 4 in such manner that a change of speed occurs at a flaw so as to mark the tube in the vicinity of the flaw. The detecting means may be mounted to rotate with the cutter head. Reference is made to the use of ultrasonic tracers, eddy-current tracers and induction coils or cutting force or friction measuring instruments for the detection of the flaws and these may be used in conjunction with various, e.g. electronic control elements. The bars or tubes may be fed from a feed rack 1 and discharged to a discharge rack 2 and are mounted for machining in clamping jaws 6, 7 adapted to be released and lowered to allow passage of the cutter head 3.

Abstract: 1335828 Regulating PERKINS ENGINES Ltd 19 April 1971 [13 Feb 1970] 7011/70 Heading F1B [Also in Division B7] A motor vehicle power unit and transmission comprises an I.C. engine(20), Fig.3 (not shown), change speed gears (29) incorporating gearratio selection mechanism (30) and fuelling control means (35) operative in response to the selection of an intermediate gear ratio so as to adjust a variable delivery fuelling device (27) to be capable of delivering a predetermined increased maximum quantity of fuel. The fuel control means consists of a sensor (33) on the gear box (29) connected to an actuator unit (35) operable to vary the maximum output of the fuel pump (27) supplying metered fuel to injectors (28). Movement of the gear lever 30 Fig.4 into intermediate gears ratios closes micro-switches 36, 38 Fig.4 which energize solenoids S2, S4 to move plates 41, 42 into the path of the fuel pump control rod 43. The plates 41, 42 are engaged by rod 43 and move together until stopped by a fixed abutment (not shown). The different thicknesses at TN, T4 are variously combined to permit an increased maximum movement of rod 43. In another embodiment fuel is pumped through a metering valve R51, Fig.5 by a transfer pump R52 to be fed to injectors 54 by a rotary distributer including plungers R56 engaging a cam R57. Two position spring-loaded valves 64.65, each incorporating a flow restrictor, are associated with the intermediate gear ratios and each normally connects the fuel metering conduit to a sump. Hydraulic selection of an intermediate gear ratio causes operation of the respective valve thereby reducing the fuel flowing to the sump and increasing the supply to the fuel injectors. In a modification the gear ratio selection is by pressure switches (67), Fig.6 (not shown) which are electrically connected to a logic unit (68) which permits an appropriate escape flow of fuel from the fuel metering conduit, the fuel control characteristics being modified by the gear ratio in use in a twospaced rear axle (69).
