Patent GB-923316-A (GB)
Title: Improvements in and relating to internal combustion engines
IPC: F02C3/20
Filed: 1959-07-09
Abstract: <PICT:0923316/III/1> A combustible gas containing carbon monoxide and hydrogen is produced in an internal combustion engine such as a gas turbine by reacting in a reaction chamber outside the combustion chamber of the engine, a liquid or gaseous engine fuel and water either as a liquid or steam or the engine fuel and an emulsion of a hydrocarbon and water, if necessary in the presence of a catalyst, the heat for the reaction being supplied by the waste heat of the engine and the combustible gas produced fed to the engine.  The reaction chamber may surround the combustion chamber so that heat for the reaction is supplied through the walls of the combustion chamber. Alternatively or in addition the heat required may be extracted from the waste combustion gases.  In the apparatus shown in Fig. 1 a hydrocarbon-water emulsion is fed from a tank 1 to a reaction chamber 9 heated by hot combustion gases from line 16.  The gas produced in the chamber 9 is passed to a combustion chamber 10 supplied with pre-heated air by a compressor 23, line 24 and a heat exchanger 22 traversed by the hot waste combustion gases after having heated the reaction chamber.  The hot gases from the combustion chamber 10 are supplied first to a compressor turbine 12 and then to a working turbine 14 and the exhaust line 16, the turbine 14 being connected mechanically to a generator 15.  Some of the hot waste combustion gases may by-pass the reaction chamber.  In starting up the apparatus a hydrocarbon fuel from a tank 5 may be supplied to the combustion chamber 10 via line 27.

Abstract: 1,171,828. Cathode-ray storage tubes. WESTINGHOUSE ELECTRIC CORP. 22 May, 1967 [10 June, 1966], No. 23660/67. Heading H1D. An information storage system includes a storage target having a porous, highly resistive member of less than 10% bulk density with a conductive layer on one surface; a gun for directing a flooding beam of electrons upon that surface with sufficient energy to penetrate the conductive layer and leave the other surface of the porous member uniformly changed; a scanning gun for directing a beam upon the charged surface of the porous member; an input circuit for modulating the scanning beam with the information to be stored, and an output circuit for deriving an output signal from the storage member under exposure to the scanning beam, and means for connecting either the input or the output circuit to the conductive layer for writing and reading respectively. The target 30 is composed of a porous layer of potassium chloride, magnesium chloride, or magnesium oxide, with a free surface facing the scanning gun 14 and the other surface separated by a conductive layer of aluminium from a supporting layer of aluminium oxide. The target is primed by a high energy pulse-e.g. of a millisecond-from flood gun 50, whereby the free surface of the porous layer is positively charged to a potential determined by the grid 40. Information is then written upon the primed target by the lowenergy scanning gun 14, a modulating signal, corresponding to the information, being applied, via switch 43, either to the control grid 20 or, preferably, to the conductive layer in the target, and is subsequently read out, via switch 43, by scanning with the beam unmodulated. The priming pulses from gun 50 may be arranged to coincide with the return time of the vertical deflection of the scanning gun 14.

A method of manufacturing electrodes for electrolytic processes &c. comprises compacting titanium, or an alloy of titanium having similar anodic polarization properties, in powder form to produce a sheet, scattering on at least one surface of the sheet a material which is in powder form and has a more positive electrode potential than the metal of the sheet, and rolling the compacted sheet and scattered powder together. Suitable titanium alloys contain 5% zirconium or 2.5% niobium. The more positive material may be platinum, or an oxide, e.g. of lead or manganese, or a mixture of powdered platinum and powdered oxide of lead.

Title: Improvements in internal combustion engines operating with slide valves in the cylinder heads
IPC: F01L5/04
Filed: 1936-09-01
Abstract: 458,253. Valves. KRUPP GERMANIAWERFT AKT.-GES., F., Kiel-Gaarden, Germany. Sept. 1, 1936, No. 23923. Convention date, Sept. 7, 1935. [Class 7 (vi)] In engines having inlet or exhaust ports controlled by a slide valve in the cylinder head, the valve-actuating gear is relieved of all stress due to cylinder pressures during the compression and combustion periods, by locking the valve in a position in which it abuts directly against the working cylinder or a part rigidly connected thereto. The Figure shows a piston valve f controlling exhaust ports d and actuated by cams q, a bifurcated lever k, and a link m, the locking being effected by rotation of the valve so as to bring teeth n thereon into alignment with corresponding teeth o on an extension p of the cylinder. Before the valve is moved back to uncover the ports d, it is rotated back again so that the teeth n pass between the teeth o. The rotary movement of the valve is effected by cams r<1>, r<2> and links s<2>. In a modification, the teeth o are carried by a ring which is rotated instead of the valve. The cams q are so designed that the teeth n, o do not bear against each other when the rotary movement is being effected. The valves may control inlet instead of exhaust, and may be annular with a fixed central insert.

Title: Apparatus for making recording and reproducing films, particularly sound films
IPC: G03B31/00
Filed: 1929-08-03
Abstract: 337,772. Selenophon Licht-und Tonbildges. April 17, 1929, [Convention, date]. Film-feeding machanism; optical apparatus.- Relates to apparatus for producing or reproducing from films of the kind having a number of photographic records thereon, running alternately in opposite parallel directions. According to the invention, which is particularly applicable for use with sound records, means for driving the film in either direction at will comprises two friction rollers R<1>, R<2>, with which coact two pressure rollers D<1>, D<2>, which are coupled together in such a manner that only one of them can operate at a time. Either of the rollers R<1>, R<2>, can be brought into action as required by pressing the film against it b means of the corresponding roller D<1> or D<2>. Figs. 1 and 2 show two alternative arrangements of the rollers. Movement, of the mechanism for effecting reversal of the film drive may also cause the optical system to be traversed across the film so as to shift the light beam into position for making, or reproducing from, an adjacent sound-trace. The device shown in Figs. 3a and 3b, comprises a rack Z movable endwise by means of a pinion the rack gearing with wheels N<1>, N<2> which operate pressure rollers D<1>, D<2>. The driving roller R<1> and pressure roller D<1> are shown in engagement with the film F. By shifting the rack Z upwardly, the roller D<1> is moved away from the film, and the roller D<2> is simultaneously moved so as to press the film against the roller R<2>, which then reverses the movement of the film. At the same time, a screw S on the shaft of the pinion N', having a bearing in a movable wall W which carries the optical system O, causes the latter to move the required distance across the film.

Class 110(ii) A stream of compressed air is divided, one part being expanded through an engine which drives a compressor through which passes the second part of the stream of air to be raised in pressure. The latter, with its temperature raised is circulated, e.g. around a jacket 19 on the engine 2, and the exhaust from the engine is circulated through a jacket 18 on the compressor 1, for cooling purposes, being exhausted through a port 25. The unit, which may comprise an engine 2 and a compressor 1 of the outwardly-sliding vane type, may be placed in an air hose leading to compressed air tools in a mine, and have a relatively low-pressure supply 12, for both engine and compressor, and a delivery 30 where air at higher pressure is conveyed onwards. Air supply to the engine 2, from a duct 13, is regulated by a centrifugal governor 16 acting on an inlet valve 15, the air feed passing through a duct 21. Air exhausted from the engine flows through a liner 8 to the jacket 18. The compressor has a liner 3 provided with inlet ports 27. A cover 32 allows easy access to the interior of the unit.
