Patent GB-579624-A (GB)
Title: Improvements in internal combustion engines operating with oscillating and rotary valves
IPC: F01L7/08
Filed: 1944-06-09
Abstract: 579,624. Valve gear; valves; cooling cylinders. COCHRANE, W. June 9, 1944, Nos. 11039/44 and 12029/45. [Classes 7 (ii) and 7 (vi)] A multi-ported conical valve 1 is rotated or oscillated against a correspondingly shaped seating 2, extending into an inlet chamber 3 through which the exhaust gases pass to heat the charge before admission to the cylinder. As shown in Figs. 1 and 2, the valve has four ports which register with inlet and exhaust ports and carries a pinion 15 which is rotated by racks 16, 17, mounted on rack bars 18, 19, carrying rollers 22, 23, and cams 24, 25, on a shaft 26, driven from 'the crankshaft. On the exhaust stroke the ports 6, of valve 1, are fully open to the exhaust ports so that the exhaust gases pass out through ducts 10, traversing the inlet chamber 3, and heat the charge. The cam 24 next forces the rack bar 18 to the left in Fig. 2, and through the rack 16 and the pinion 15, rotates the valve to close the exhaust ports and to bring the ports 6 fully open to the inlet ports. Near the end of the induction stroke one of the two humps on the cam 25 thrusts the rack bar 19 to the left, Fig. 2. and the valve is rotated by the rack 17 and the pinion, so that both inlet and exhaust ports are closed. The valve 1 remains stationary during the compression and firing strokes. When the exhaust occurs the second hump on the cam 25 completes the movement of the rack bar 19, so that the valve opens the exhaust ports. One or more sparking-plugs 31, a compression relief valve and a fuel injector fed by a variable-stroke fuel injection pump may be uncovered at the appropriate times by the ports 6. In a modified construction the valve is oscillated by a single rack operated by a cam track on a cylindrical cam and movements of the valve and rack are damped by inertia springs. In a two-stroke engine the valve may be operated intermittently by a Geneva stop mechanism the valve controlling only the exhaust ports. Mixture or air supplied by a compressor is heated in the chamber 3 before entering the cylinder through piston-controlled ports. Cylinders, cooling.-In a 24-cylinder aircraft engine the cylinders are arranged as shown in Fig. 13 in banks of six with the cooling fins parallel to the direction of flight. Specification 532,977 is referred to.

Patent GB-166948-A (GB)
Title: Improvements in and relating to compressors, blowers or the like driven by reciprocating engines or elastic fluid turbines
IPC: F04B49/22
Filed: 1920-04-21
Abstract: 166,948. British Thomson - Houston Co., Ltd., and Collingham, R. H. April 21, 1920. Regulating or controlling.-The power required to drive a centrifugal fan or compressor is reduced by the provision of a balanced valve 10 in the inlet; the valve is adapted to be opened or closed when the pressure in the receiver reaches certain definite adjustable limits, the pressure at which the valve is opened being lower than that at which it is closed. A weighted rod 4 carries the piston 2 working in the cylinder 3 and is connected bv a series of links to the valve 10, which rotates in a frame 11 secured to the pump inlet by bolts with compression springs. A pipe 22 connects the cylinder 3 to the cylinder 21 having rigidly connected pistons 16, 20, the latter of which acts as a dashpot. The upper end of the pistons carries an adjustable weight 15 and a catch 23 engaged by a trigger 24. The lever 26, carrying the trigger, has a roller 27 resting on the upper end of a piston 28 and a. stirrup 32 supports a weight 29 from the lever 26. The control cylinders are connected by pipes 18, 19 to air receivers on the pressure side of the compressor. The control gear is adjusted to operate between fixed upper and lower limits by adjusting the weights 15, 29, and the valve 10 is fully open during normal working. As the demand ceases the increase in receiver pressure causes the piston 28 to rise so that the trigger 24 engages the catch 23. With higher pressure still the piston 16 rises and connects the pressure to the cylinder 3 through the pipes 18, 22, so that the piston 1 rises to close the valve 10. The compressor then runs in a partial vacuum and demands only minimum power. When a fresh demand is made on the air supply, the reduced air pressure permits the piston 28 to drop and release the trigger 28 from the catch 23. The weight 15 and piston 16 then descend against the dash-pot action of the piston 20. The piston 16 disconnects the pipe 18 from the cylinder 3 and connects the cylinder to the atmosphere through the port 17. The piston 1 then drops and opens the valve 10.

Title: Improved treatment of artificial silk
IPC: D06M13/12
Filed: 1924-05-05
Abstract: The water-resisting properties and the sheen of artificial silk, staple fibre, and the textiles made therefrom, are increased without impairing the softness or dyeing properties, by treatment simultaneously or successively with aldehydes, particularly formaldehyde, and with inorganic or organic bases, or with salts of a basic character or with ammonium salts or with mixtures thereof, and then after the removal of the material from the impregnating-solutions, and preferably after removing the main quantity of liquid, subjecting the material to temperatures above 90 DEG  C., preferably between 120-170 DEG  C., under conditions such that any remaining moisture may escape, whereby the silk &c. is simultaneously consolidated and dried.  As an alternative, the products impregnated with the bases, salts, &c., are treated with formaldehyde vapours and at the same time heated to a temperature above 90 DEG  C.  Suitable inorganic bases are sodium and potassium hydrates; but it is preferred to use alkaline-reacting salts or salts the basic component of which is stronger than the acid component, such as alkali, alkaline earth and magnesium acetates, formates, lactates, oxalates, tartrates or citrates, or alkali or ammonium carbonates, borates, sulphides, phosphates, sulphites, silicates and oleates, or ammonium salts of acids weaker than dichloracetic acid and stronger than acetic acid.  In examples, the basic substances employed are sodium hydrate, calcium lactate, sodium formate, and sodium oxalate; and air or inert gas such as nitrogen or hydrogen may be passed through the drying-chamber during the heating operation.

Abstract: 770,448. Making casting electrodes; powder metallurgy. IMPERIAL CHEMICAL INDUSTRIES, Ltd., and ATTKINS, R. March 23, 1955 [April 21, 1954], No. 11452/54. Classes 83 (2) and 83 (4). [Also in Group V] In manufacturing a consumable electrode for the arc melting of high-melting-point metals or alloys, e.g. titanium, zirconium, thorium, hafnium, tantalum, molybdenum, chromium and their alloys, in a succession of cycles of operation, each cycle includes feeding a charge of the metal or alloy to be melted in divided, e.g. sponge or powder form to a die chamber 2, securing the charge, by compacting, on to a length of a continuous element within the chamber and withdrawing a substantial part of the compact from the chamber, thereby to feed another length of the element into the chamber. In the embodiment sponge or powder titanium is fed from a hopper 1 and the element is a wire 11 of titanium, but may be of an alloy of the basis metal and alloying agents, or of an alloying agent or agents. The wire, fed over a guide roll 12, is held stationary while divided titanium is fed into the chamber 2 and the sliding members 4 are then closed. The members 6, 6 are poweroperated and compact the charge shaping, e.g. tapering the end of the compact to fit the adjacent end of an adjacent segment. Rolls 10 withdraw the composite electrode at a speed conforming to the rate of melting of the end of the electrode in a crucible 9 until the segment 13 is in the position shown. To obtain positive keying the wire may be serrated or the element may be perforated, embossed, dimpled or expanded metal strip and heating may be applied during compacting. A plurality of dies may produce a plurality of electrodes fed into the same furnace. As an alternative to feeding the electrode directly to the arc electrodes may be built up, separated and subsequently fed to a furnace.
