Filed: 1972-06-14
Abstract: 1387495 Power assisted steering systems ZAHNRADFABRIK FRIEDRICHSHAFEN AG 14 June 1972 [24 June 1971] 27814/72 Heading B7H In a power assisted steering system, supplied by an accumulator circuit, a control device, comprising a control valve 8 having reaction pistons 64, 65 and a steering force limiting assembly 9, is arranged so that the reactive "feel" is reduced by the action of assembly valve 9 during parking. Valves and assembly 9 are mounted in a spindle 5 and are interconnected by bores 28, 29, actuating pins 10, 11 carried by a steering shaft 6 engage the valves and are positioned to engage stops 12, 13 on the spindle. Control valve 8 includes a sleeve 57 having grooves 45, 46, 58, 59, a spool 48 having grooves 61, 62 and combined reaction pistons 64, 65 and conical valves 49 having grooves 60, 63. Whilst shaft 6 is undeflected, fluid is supplied to grooves 45, 46 from the accumulator circuit (Fig. 2, not shown), and pressure chambers 21, 22 are interconnected via lines 30, 31 and bores 28, 29. On turning shaft 6 during normal driving spool 48 moves to unseat a conical valve 64 or 65, and fluid flows from groove 45 or 46, to groove 61 or 62 and thence via bore 28 or 29, and line 30 or 31 to chamber 21 or 22. Fluid in groove 61 or 62 passes to reaction spaces 70 or 71 via bores 66 or 67 and 68 or 69 to give the "feel" effect. The assembly 9 includes pistons 75, 85 slidably mounted in bushes 76, 86 having grooves 87, 77, the pistons being loaded by spring 80, 90 and abutting discs 73, 74 contacting the pin 11. The springs 80, 90 are pre-loaded so that with normal pressures, i.e. during normal driving, pressure acting on piston faces 78, 88 will not move the pistons 75, 85, however, during parking, with high pressures in the system, fluid from the control valve flowing in bore 28 or 29 will act on one of the pistons to move it to act on pin 11 in a direction assisting the rotary movement of the shaft 6. This action will reduce the reactive force of piston 64 or 65.

Abstract: 746,513. Photo - electric gloss meter. BOWATERS DEVELOPMENT & RESEARCH, Ltd. Sept. 21, 1954 [Oct. 12, 1953], No. 28071/53. Class 40 (3). Apparatus for measuring the gloss of a surface 5 makes use of the polarization of specularly reflected light. As shown, light from source 2 falls on the surface and is both diffusely and specularly reflected through a diaphragm 6 on to a photo-electric cell 14. In the path of the light to the cell is a drum 7 of sections of "Polaroid" (Registered Trade Mark) adjacent section being polarized at right angles to each other. The drum may consist of the polarizing elements sandwiched between transparent non-polarizing cylinders such as " Perspex" (Registered Trade Mark). Inside the drum and in the path of the light to the cell is a rotatable analyser 11 provided with a scale 13. The planes of polarization of the segments are such that one passes both diffusely and specularly reflected light and the other diffusely reflected light only. The photocell output is connected to an A.C. amplifier the output from which is rectified and displayed. In use the analyser is rotated to bring the amplifier output to a minimum when the scale 13 indicates gloss directly. To avoid confusing interference due to the joints between the segments, these joints are deliberately made opaque thus introducing a second harmonic which may be removed by a filter. Further opaque bars may be inserted to make the disturbance a higher harmonic.

Title: Improvements in or relating to mosaic screens
IPC: H01J29/43
Filed: 1945-10-26
Abstract: 598,501. Cathode ray tubes. AMBROSE, E. J. Oct. 26, 1945, No. 28280. [Class 39 (i)] A method of manufacturing a mosaic screen for a television transmitting tube comprises forming on a support member a silica layer and then heating to cause it to split up and form discrete insulating elements. The screen may comprise a glass or mica support on which is deposited a silica layer about 1-2 Á thick. The silica layer may be applied as a coating of silicon tetrachloride or a silicon ester and hydrolysed in the vapour of hydrochloric or nitric acid or ammonia, or, alternatively, by flow-coating a solution of a silicon ester in acetone and spinning the support to provide an even coating. In another method, quartz is evaporated on to the support. Heating is effected to about 100‹ C. A metal film, such as antimony, bismuth or alloys of these metals with nickel, platinum or palladium may be evaporated on to the discrete elements. To ensure that the elements remain insulated from each other, an electric discharge may be applied to the surface of the screen to rupture the metallic film, or the metal may be evaporated at an oblique angle to the surface. Alternatively, the conducting elements may be deposited on to the silica layer prior to the heating operation and consequent formation of discrete elements. Finally, the screen may be photo-sensitized, for example with caesium. In another form of television transmitting tube, the target -is not photo-sensitive, but receives an electron image at such energy that secondary electrons are emitted. According to the Provisional Specification, discrete insulating elements may be produced by settling minute glass or mica flakes on to the support. The flakes of glass may be prepared by grinding films of glass and allowed to settle from a suspending medium on to a glass plate preferably roughened or ground.
