Title: Improvements in fluid flow control valves
IPC: F16K11/085
Filed: 1962-02-19
Abstract: 963,792. Valves. REALM ENGINEERING WORKS Ltd., H. C. NORTH, and S. C. NORTH. Feb. 13, 1963 [Feb. 19, 1962], No. 6339/62. Heading F2V. A fluid flow control valve of the multi-way type comprises a valve body 3 having ports a, b, c, d, a rotary cage member 9 within the body and connecting ducts 27 supported within the cage member, the connecting ducts being relatively movable within the cage and being adapted to be pressed outwardly into sealing engagement with the ports. Flexible packing members 29 of rubber or synthetic rubber are released from sealing engagement with the ports when pressure applied to the ducts through levers 43 pivoted at 44 is relieved by downward movement of a piston-rod 25. This movement may be produced manually or by electrical means, by a spring 37 or by fluid pressure acting above a piston 24. Rotation of the cage is effected by a pinion 31 in engagement with a rack on double-acting piston and cylinder 11 while a micro-switch 46 operated by a cam 45 is connected to a valve-position indicator or feed-back system. The body interior may be flushed out by cleaning liquid fed through unions 48.

Abstract: 903,769. Valves. ROBERTSHAW-FULTON CONTROLS CO. Feb. 24, 1959 [June 23, 1958], No. 6371/59. Class 135. A thermostatic valve for an I.C. engine cooling system comprises a fixed mounting member 24 having a valve seat 26 and a first abutment means 30, a hollow cylindrical valve member 32 carrying a ring abutment means 44, thermal means having relatively movable upper and lower portions 50, 48 in operative engagement between the abutments on the fixed member and the valve, and yieldable means 64 in tension between the valve and the lower portion of the thermal means. On increase in temperature and elongation of the thermal means valve 32 is moved away from seat 26 against the tension of spring 64 allowing fluid to flow from chamber 10 to chamber 14 until the ported upper end of the valve closes at 36 on an upper seat 38 to prevent flow from the chamber 10 through the valve to chamber 16. On further expansion of the element the lower part of the element moves away from its abutment 30 against springs 64 and 60.

Title: Improvements in or relating to bowden mechanism
IPC: F16C1/26
Filed: 1936-03-03
Abstract: 471,203. Bowden mechanism. TONDEUR, R., and BOWDEN (ENGINEERS), Ltd. March 3, 1936, No. 6462. Drawings to Specification. [Class 80 (iii)] [Also in Group XXVIII] With the object of reducing friction in Bowden mechanism the outer member of which is constructed of two or more closely interwound relatively laterally displaceable coils, for example, as described in Specification 412,367, the wires of the coils are of dissimilar metals or metal alloys, or of the same metal or metal alloy, but coated with different metals or metal alloys. Thus, with two interwound high tensile steel wires of trapezoidal section, the wire wound base inwards may be given a coating of tin, and the wire wound base outwards a coating of zinc, copper, and copper alloy, e.g., phosphor or aluminium bronze or vice versa. Alternatively one wire may be of phosphor or aluminium bronze or a metal known under the Registered Trade Mark "Duralumin" and the other of high tensile steel coated with tin. One wire may be of circular section, and various combinations of metals and coatings are described. In general, the metal or coating of the wire wound base inwards should have the better antifriction and that of the wire wound base outwards, the better anti-corrosion properties. The inner member may be a single or stranded wire of, or coated with, different material from that of or coated on the wire of the outer member with which it is in contact. For example the inner member may be coated with zinc, and the trapezoidal wire wound base inwards with tin.

Title: Improvements in or relating to television receivers
IPC: H04N5/50
Filed: 1960-02-24
Abstract: 932,397. Tuning indicator arrangements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 24, 1960 [Feb. 27, 1959], No. 6481/60. Class 40 (5). The tuning indicator circuit of a single sideband television receiver has a resonant circuit tuned to the central position of the "Nyquist Flank," Fig. 2b, of the receiver response curve, which includes a voltagecontrolled reactance element controlled by the receiver automatic gain control voltage. The receiver intermediate frequency signal from terminal 1 is fed to the resonant circuit 4, 5 and the resulting output is rectified by diode 7 and applied to the tuning indicator tube 11. In parallel with the circuit 4, 5 is a reverse biased diode 15 which behaves as a capacitance controlled by the a.g.c. signal from terminal 22. For normal strength signals, the circuit resonates at the mid-point of the Nyquist Flank, Fig. 2b, but for weak signals, the bias on the diode, and hence its capacitance changes and the point of correct tuning as indicated by the tube 11 moves further up the slope. If the receiver is intended for reception of transmissions having pre-distortion of phase, then to receive undistorted transmissions the tuning point must be moved down the Nyquist Flank. This adjustment may be made by varying the bias potentiometers 17, 18, 19 and adjusting potentiometer 21, conveniently by operation of the channel selector switch. The variable reactance 15 may take other forms, e.g. a ferro-magnetic core in the inductor 4. If manual adjustment of the resonant circuit is required, this is preferably cancelled when the channel is changed, so that the pre-set adjustment is again effective.

Title: Improvements relating to optical devices
IPC: H04N3/00
Filed: 1965-02-17
Abstract: 1,060,203. Deflecting light. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1965 [March 6, 1964], No. 6753/65. Heading H4F. The region of maximum brightness of a parallel beam of monochromatic light produced by source 1 and lens 2 is linearly displaced on screen 6 in a first embodiment by means of an optical device comprising a wedge-shaped electro-optic birefringent crystal 4 positioned between crossed polarizers 3 and 5, the birefringent properties of the material of the crystal being varied by applying a variable electric field to transparent electrodes 4a and 4b on opposite surfaces of the crystal. Crystal 4 is located so that the optical axis of the device extends perpendicular to the surface of the crystal adjacent to polarizer 3, the optical axis of crystal 4 lying in the light entry plane so that the ordinary and extraordinary component rays are not refracted but advance with different speeds. Depending on the length of path traversed within the crystal the phase difference between each pair of ordinary and extraordinary component rays has a value ranging between 0 and 180 degrees when they recombine on emergence from the crystal, i.e. each ray of light emerging from the crystal is linearly polarized in its original direction, elliptically polarized, circularly polarized or linearly polarized at 90 degrees to the original direction of polarization. By varying the electric field applied across the wedge-shaped electro-optic birefringent crystal the point of maximum brightness on screen 6 is displaced in the direction of the length of the wedge since the optical properties, i.e. birefringent properties, of the crystal are varied. In a second embodiment, Fig. 2, not shown, the wedge-shaped electro-optic birefringent crystal is replaced by a wedge-shaped birefringent crystal and an electro-optic crystal in the form of a plane-parallel plate with opaque electrodes having a central slit on opposite surfaces. To improve the focusing of the beam of light transmitted through polarizer 5 (the light intensity follows a cos<SP>2</SP> law) a plurality of the above optical devices may be arranged in series with their directions of displacement of the region of maximum brightness parallel. The wedge-shaped crystal is preferably cut so that only one point of maximum brightness appears on the screen. In a third embodiment two of the optical devices are arranged in series with their directions of displacement relatively inclined, or at right angles, Fig. 3 (not shown), so that the point of maximum brightness may be scanned across the screen in accordance with a raster, the batteries in each device being replaced by saw tooth generators. The electro-optic crystals may be replaced by piezo-optic crystals, the birefringent properties being varied by mechanical stresses.
