Title: Means for deriving energy from solid fuels
IPC: F02C3/26
Filed: 1949-11-10
Abstract: 665,805. Gas turbine plant. BALDWINLIMA-HAMILTON CORPORATION. Nov. 10, 1949, No. 28863/49. Class 110(iii). [Also in Group XXVII] Solid fuel is pulverized and then placed under pressure, and substantially all the combustible fraction is extracted as gas in a substantially inert hot atmosphere; the gas is raised in pressure by a compressor or the like and burnt, the products of combustion being used to drive a heat engine. Coal from a bunker 10 is carried by a conveyor 11 to a crusher 12, where it is powdered. It is then forced through orifices 14, 14<SP>1</SP> and expanded and disintegrated by a sudden drop in pressure in a substantially inert hot atmosphere in cyclone gas extractors 52, 54. After passing through an ash separator 116 and a cooler 117, the gas from extractor 52 is fed by a booster pump 118 to a free piston air compressor 50, for which it provides driving fuel. Gas from extractor 54 is cleaned in a cyclone separator 56, raised in pressure by a pump 58 and fed to a combustion chamber 60. The combustion products drive a gas turbine 70, the exhaust of which passes through a heat exchanger 62 to preheat the air passing from the compressor 50 to the combustion chamber. Combustion gas is fed through a pipe 130 to blow the powdered coal through the orifices 14, 14<SP>1</SP>. Combustion gas is also tapped from the turbine 70 and supplied through a pipe 126 to act as secondary charging gas for the extractors 52, 54. Other embodiments are described in which a single gas extractor is used and in which the combustion chamber may be eliminated, the combustion then taking place entirely in a free piston gas generator which replaces the free piston compressor and the exhaust from which drives the turbine.

Title: Improved manufacture of alkali cellulose
IPC: C08B1/08
Filed: 1938-10-06
Abstract: 509,662. Alkali cellulose. TENNANT, W. J. (Dow Chemical Co.). Oct. 6, 1938, No. 28998. [Class 2 (ii)] Alkali cellulose is prepared by immersing a cellulosic fibre aggregate for from 0.5 to 30 seconds in a liquid bath of sodium hydroxide having a concentration between 60 and 80 per cent. at a temperature above the melting point of the sodium hydroxide solution, for example, between 55‹ and 144‹C., and passing the so-impregnated cellulosic aggregate, without pressing, through a conditioning zone wherein the temperature of the mass is maintained above the hardening point of the alkali cellulose, for example, above 40‹C., until the cellulosic fibres have absorbed the alkali solution and the mass has swelled to its maximum extent. The cellulose aggregate treated may be a continuous cellulose fibre sheet which is passed through the sodium hydroxide and conditioning chamber at a uniform rate, or cut sheets, slabs, or other forms of cellulose aggregate may be treated while on a .continuous belt or screen conveyer. The prepared alkali cellulose may be shredded and then aged, for example, by storing in a closed container in a moisture-free and carbon dioxidefree atmosphere at a temperature between the hardening point of the alkali cellulose and 100‹C. During the ageing process the alkali cellulose may be stirred or tumbled to cause the particles to be compacted into hard granules or pellets. The alkali cellulose prepared according to the invention is suitable for use in the manufacture of cellulose ethers. Examples are given which include the preparation of ethyl cellulose from the alkali cellulose.

Title: Improvements relating to methods of continuous casting
IPC: B22D11/113
Filed: 1962-08-02
Abstract: <PICT:1001134/C6-C7/1> <PICT:1001134/C6-C7/2> In a method of continuous casting the melt is caused by siphoning action to pass continuously through a chamber which is maintained at reduced pressure to effect degasification and from there directly to the casting mould, the melt being heated during its passage through the mould by induction or direct resistance heating. As illustrated in Fig. 1, melt received in container 2 is siphoned through container 3 and discharged directly into mould 6, a vacuum pump being connected to the container through pipe 10. Degassing may be aided by injecting an inert gas below the surface of the melt. Heating is effected by means of yoke 9 and primary winding 8, the secondary circuit being completed by conductive rod 11.  In the modification of Fig. 2 the melt is directly heated by current supplied through graphite electrodes forming the pipes 14 and 15, the discharge pipe 14 having a nozzle 13 of insulating material to produce a smooth jet. Alternatively current may be supplied through casting mould 6.  The "pinch effect" resulting from the flow of electric current may be used to control the rate of flow of the metal.

Filed: 1938-10-13
Abstract: 520,166. Plural tariff meters. METERS, Ltd., BRADDOCK, T. C.,. and BROWN, R. T. Oct. 13, 1938, No. 29723. [Class 27] Comprises means for effecting an automatic change of tariff when a predetermined supply of gas has been used in slot meters. The winding of the knob s rotates an arm b carrying a lever c fitted with projections or stops e, d which lie behind two tariff discs f, g. Normally the delivery ceases when the stop d contacts the stop i on the disc f, but by hand adjustment of the wheel m, driven by the run-off mechanism of the motor, a spring pivoted lever r can be caused to pass through a notch in the flange p at any predetermined time. This brings the tail of the lever r into register with the projection h on the lever c and knocks the latter aside so that the stop d is out of register with the stop i and delivery can continue until the stop e strikes the stop w on the disc g. The wheel m and lever r may be duplicated to act in conjunction with a stop on a third tariff disc to effect a further charge of tariff.
