Title: Improvements in diaphragm assemblies for operating gas or like control valves
IPC: G05D16/06
Filed: 1957-12-12
Abstract: 849,317. Valves. LOMAX, W. Dec. 10, 1958 [Dec. 12, 1957], No. 38606/57. Class 135. A diaphragm assembly for operating gas or like supply valves comprises two diaphragms H<SP>1</SP>, H<SP>2</SP>, Fig. 1, separated by an enclosed space h4, the outer face of diaphragm H<SP>2</SP> being acted on by the control pressure and the outer face of the diaphragm H<SP>1</SP> carrying the closure member E. A non-return valve D is located in the peripheral edge of the enclosed space h<SP>4</SP>. The diaphragm operated valve assembly is used in a water heater gas supply unit as described in Specification 849,318 so that when water is flowing from the heater the diaphragm H<SP>2</SP> is subject to suction to effect opening of the gas supply valve E. If the diaphragm H<SP>2</SP> is damaged and the pressure in the space h<SP>4</SP> falls, the non- return valve D mounted in the spacing ring M will admit air so that the diaphragm H<SP>1</SP> is flexed upwardly to close the valve E.

Abstract: 1483848 Rotary positive-displacement fluidmachines HOKUETSU KOGYO CO Ltd 19 Sept 1975 [24 Dec 1974] 38619/75 Heading F1F In a meshing-screw compressor, a cooling, lubricating and sealing liquid is injected through openings 15 in a throughput-controlling slide-valve 10 at a rate commensurate with the gas throughput, the volume flow-rate L of the liquid expressed as a percentage of the volume flow-rate of the liquid at fullload being kept between an upper limit 103 - 330/G+10 and lower limit 4/5G + 20, where G is the volume flow-rate of the gas expressed as a percentage of the volume flow-rate of the gas at full-load. The liquid is supplied from a gas and liquid separating tank 28 and passes through overlapping slots 16, 22 in the valve and the casing 1 so that the flow-rate of the liquid is regulated in accordance with the setting of the valve, which is effected by a piston 18. Liquid collected in a discharge chamber 34 is extracted by a pump 36. Other embodiments, Figs. 3-6 (not shown), differ only in that the slots are formed in co-axial relatively slidable tubular elements associated with the valve 10. In a further embodiment, Fig. 7 (not shown), the flow-rate of the liquid is regulated by a needle-valve attached to the valve 10.

Title: Improvements in the process of reflex copying by the use of fiber optical devices
Inventor: HERRICK CLIFFORD ERNEST
IPC: G03C5/10
Filed: 1960-11-18
Abstract: 922,705. Copying-apparatus using transparent films. GENERAL ANILINE & FILM CORPORATION. Nov. 18, 1960 [Dec. 7, 1959], No. 39767/60. Classes 97 (1), 98 (1) and 98 (2). A method of copying an original by the reflex method comprises placing an original and a base having a light-sensitive face in spaced superposed relation, placing a fibre optical device in the space between them and illuminating the original so that light reflected from it is conveyed by the device to the base. In the apparatus shown in Fig. 21, the original and the copy sheet are fed together between moving belts 27, 28 into the apparatus and are then separated, and moved along belts 33, 32 respectively, where the original is illuminated by light from lamps 37, provided with mirrors 38, and the light reflected from the original is conveyed by a block of glass fibres to expose the copy sheet. Vacuum boxes 43, 44 hold the copy sheet and original flat, the original then leaves the apparatus by channel 42 and the copy sheet by a channel formed by moving belt 40 and guide 39. A variable-speed motor 49 drives the belts and also operates a fan for cooling the apparatus. Other arrangements of lamps and fibres are described, e.g. in Fig. 1 light from lamps 5 is conducted to the original 2 by fibres 4 and then reflected through fibres 1 to the copy sheet 3. Instead of fibres 4, glass blocks may be provided preferably having serrated edges. To obtain a non-mirror image bands of fibres 1 of one to three fibres thick can be twisted through 180 degrees as is shown in Fig. 6.

In the manufacture of tubing and clad rods or wires at least one metal strip is bent transversely between rollers and adjacent strip margins are squeezed together so as at least partially to solid-phase green-bond them together with the formation of a fin along the or each pair of margins, sintering the strip and eliminating the fins. Fin portions 4 are formed by heads of the rolls R and when using hard metals, e.g. nickel, stainless or " Monel " (Trade Mark) steels, there is a comparatively weak green-bond in the region of the fins. Before removing the fins 4 a uniform bond is obtained by sintering. The fins may be removed in skiving apparatus comprising V-shaped guide wheels W flanked by skiving blades S, Figs. 7 and 8. In cladding wires or rods, the outer sheet(s) 2, 3 are green-bonded to the core 1, which may alternatively be a tube, during the initial rolling and when forming a tube the sheet(s) are formed around a mandrel (M) (Fig. 6, not shown). Alternatively the fins may be removed by drawing, rather than, or in addition to, skiving.
