Title: Improvements in and relating to free-piston air-compressors
Inventor: BEALE EVELYN STEWART LANSDOWNE
IPC: F04B31/00
Filed: 1954-09-09
Abstract: 772,302. Compressors. MUNTZ & CO., Ltd., A. Aug. 23, 1955 [Sept. 9. 1954]. No. 26199/54. Class 8(1) In a free-piston air compressor having one or more valves controlling the delivery of air from a compressor cylinder to a reservoir and means for blocking said valves, automatically-operating control means for unblocking the valves comprises two pistons of different diameters each working in a cylinder and coupled together. In the embodiment shown in Figs. 1 and 2 the compressor cylinder 10 has a cover plate 11 with water-cooling passages 13 and apertures in which are secured by a plate 16, two valves 14, 15 of the type disclosed in Specifications 580,171 and 706,354 [both in Group XXIX] for controlling the delivery of air to passages 18 and reservoirs (not shown), the valves being blocked by plates 24, 25 yoked together by a bridge piece 27 engaged by the head of a bolt 30. This bolt is threaded into a piston rod 31 slidable in an aperture 32 formed in a part of the cover 20 to fix a large piston 23 in a cylinder 22 to a small piston 29 in a cylinder 36. The front face of the large piston 23 is always subjected to the pressure in the reservoir. the rear face of this piston and the front face of the piston.29 being always at atmospheric pressure since the space between them is open to atmosphere through a port 39. The rear face of the small piston 29 is in communication with the reservoir through a port 40 in the member 31 and through a central aperture and an aperture 37 in the bolt 30. Hence when the reservoir is at atmospheric pressure the air pressures on the piston assembly 23, 29, 31 are balanced and the whole force of a spring 38 urges the blocking plates 24, 25 against the valve faces. When the compressor is started some air is delivered through the blocked valves. the reservoir pressure rises and acts upon the large piston 23 to oppose the spring 38 and upon the small piston 29 to assist the spring until the difference between these piston forces is sufficient to move the member 31 slightly, whereupon the port 40 moves out of communication with the space behind the piston 29 and said space is connected to atmosphere through a slot 41 in the member 31 and a port 42 so that there is a sudden drop in the force urging the piston assembly to the left and the assembly "pops" to the right, unblocking the plates 24 and 25. When the pressure in the reservoir falls to a certain value the piston assembly moves to the left until the space behind piston 29 is cut off from the atmosphere and put into communication with the reservoir through the port 40 whereupon the assembly "pops" into the fully-blocking position. In another embodiment the two-piston device for controlling a valve blocking piston is separated from the compressor to avoid risk of the control means becoming fouled- or overheated by its proximity to the engine. Specifications 373,488 and 391,676 are referred to.

Abstract: 1,136,949. Electric incandescent lamps. GENERAL ELECTRIC CO. 13 June, 1966 [2 July, 1965], No. 26214/66. Heading H1F. An incandescent lamp filament consists of a coil or coiled-coil of tungsten wire, substantially free from surface layer impurities of carbon, iron or molybdenum but containing tantalum diffused into the surface layer in an amount materially less than 300 parts per million. The content of tantalum is preferably less than 100 parts per million and is effective as a getter for oxygen and hydrogen that may be present in the lamp bulb or filament. The filament may be made by winding tungsten wire 8 from a spool 10 on to a mandrel 9 of tantalum either as a continuous coil or as a series of sections 12, immersing the wire and mandrel in hot hydrochloric acid to remove iron and nickel impurities, annealing them in an inert atmosphere between 900‹ C. and 1500‹ C. and cutting the sections apart at the lines A. The sections are again immersed in hot hydrochloric acid, sintered in a vacuum furnace at between 1000‹ C. and 2500‹ C., the mandrels removed in a bath of hot hydrofluoric acid and the sections rinsed in distilled water and stored in glass containers. For making coiled-coils, the annealed filament wire and mandrel are coiled on a secondary mandrel also of tantalum before cutting into lengths. The filaments are particularly suitable for use in microminiature lamps having a bulb diameter of, for example, # inch.
