Title: Improvements in and relating to indicating control means for radio receivers and the like
IPC: H03J1/10
Filed: 1930-03-25
Abstract: 335,509. British Thomson-Houston Co., Ltd., (Assignees of Mapelsden, H. H.). May 29, 1929, [Convention date]. Adjusting wireless apparatus.-A source of light such as a lamp 39 is arranged to project a beam of light through the scale 37 so as to produce an enlarged image of the graduations &c. thereon on a translucent screen 38 spaced from the scale 37. The screen 38 may be of translucent sandblasted amber or brown celluloid, the scale 37 being of white or transparent celluloid blackened except for graduations and indices, or of metal with perforated graduations. The lamp 39 is arranged behind a shield 40 so that its filament is opposite a small orifice 41. Alternatively the lamp may be wholly enclosed in a tubular shield having one end closed by a flat plate in which is a small rectangular or other orifice. The scale 37 is carried by a segmental disc 43, which is also secured to a drum 14 mounted on the shaft 11 of the member to be controlled. The drum 14 is driven, by means of a cord 29, from a driver shaft 17 to which is fixed a knob 18 and a sheave 31. The ends of the cord 29 are passed through a hole 21 in the drum 14, tied together, and attached to the end of a spring 22 to take up any slack. Two springs at an angle may be employed, so as to leave the centre of the drum free for the shaft. The cord 29 is wrapped around the drum 14 in a helix so that it engages and leaves the drum in different planes. The cord passes over an idler pulley 30 and is wrapped about the sheave 31 for a few turns. It is then secured to the sheave, as by passing through a hole 32, and the wrapping is continued. On rotating the knob 18, the cord 29 is wound onto and unwound from the sheave 31 at the same rate, the tension of the cord being thereby maintained constant. In order to provide a stop for the driver shaft 17, a collar 55 is mounted freely thereon and carries an exially extending stud 56 and a radial stud 57. The stud 56 engages a stud 59 carried by the shaft 17, and the stud 57 engages a stud 58 carried by a bracket 19. Two complete rotations of the shaft 17 are thus permitted, and are sufficient to move the scale 37 through 180‹.

Abstract: 124,965. Neighbour, A. G. L., and Neighbour, H. C. W. June 11, 1918. Valves, arrangement of. - A pump or compressor comprises a cylinder 1 in which a piston 2 is reciprocated by a crank-pin 7 on a shaft 5 rotatably mounted in a bearing 4 in a boss 3 on the cylinder. The pin 7 engages a valve-block 13 slidably mounted in a transverse slot 9 in the piston and controlling the admission of fluid to the ends of the cylinder through ports 17 in the piston. The slot 9 ends in a recess 16, which is always open to the inlet 15. The fluid is delivered through valves 18 into a delivery chamber 19 provided with an outlet 20. The piston may carry a pin 21 engaging a slot in the cylinder to prevent it from rotating. The pump may carry a flange 28 for attachment to a wall, &c., or it may be mounted on feet. In assembling the parts the valve block is inserted in the slot 9, the piston is then placed in the cylinder in mid-stroke position, the shaft 5 is passed through the bars 3, the pin 7 is pushed into the block 13, and the bearing 4 is then placed on the shaft 5 and fixed. In a modification, the valve block is hollow and longer than the block shown in Fig. 1, and has ports in its walls, adapted to register with the ports 17; and the cylinder has two opposite reverses, one containing' the inlet, the other containing lubricant into which the end of the valveblock dips in its lowest position.

Patent GB-1002793-A (GB)
Title: Ruthenium and ruthenium alloy metal-glass resistance materials and resistance elements constructed therefrom
IPC: C03C17/06
Filed: 1964-03-06
Abstract: A metal-glass resistance material is fired on to an insulating base to form a resistance layer having a low temperature coefficient of resistivity, the material comprising a finely divided mixture of 60-99% by weight of glass, the balance being ruthenium or ruthenium alloyed with gold, palladium or platinum, or combinations thereof. For elements using only glass and ruthenium, the latter forms 1-10% b/w. The minimum ruthenium content when alloyed is 2% b/w. of the alloy.  The resistance material is prepared by mixing resinates of the metals with very small glass particles to wet them, heating to 700 DEG  F. to remove volatiles and organic materials, and to decompose the metal compounds, grinding the resulting dry material, and calcining at 850 DEG  F.  Further grinding results in a fine powder of small glass particles each coated with an extremely thin layer of metal.  The powder is mixed with a liquid carrier, applied to the base and fired.  The base may be steatite, alumina, fastenite or a zircon porcelain.  Examples of the glasses used are (figs. in %): ....(1).(2).(3) .PbO...65.68.58.10.75.15 .ZnO...5.41.5.41.5.40 .MgO...-.0.39.- .B2O3...10.00.11.30.9.04 .SiO2...16.51.24.50.13.41 .ZrO2...2.40.1.20.- The glass may be made by thoroughly dry mixing a batch of raw materials, melting in a ceramic crucible to give a clear fluid glass, and pouring the glass into cold water.  The resulting shattered glass is dried and ground to a fine powder.
