Title: A Method for Producing Vinyl Acetate
IPC: C07C69/01
Filed: 1967-06-07
Abstract: 1,164,194. Vinyl acetate. KURASHIKI RAYON K.K. 7 June, 1967 [7 June, 1966; 31 March, 1967], No. 26287/67. Heading C2C. Vinyl acetate is prepared by reacting ethylene, oxygen and aqueous acetic acid (water content 27-77 mol. per cent) in a gaseous mixture in which the partial pressures of oxygen and acetic acid are each not more than 0.15 atmospheres, in the presence of metallic palladium catalyst. The vinyl acetate is separated and recovered from the product and aqueous acetic acid with a water content of 27 to 77 mol. per cent is recirculated. The catalyst may be deposited on a carrier, e.g. lead alumina, silica, magnesia, kieselguhr, pumice and active carbon, and a metal acetate, e.g. alkali or alkaline earth metal acetates, may be present. Carbon dioxide may be included in the reaction gases. Examples are described with the aid of a flow diagram.

Abstract: 923,894. Nuclear power plant. P. MALDAGUE. July 31, 1959 [Aug. 4, 1958], No. 26407/59. Class 39 (4). [Also in Group XIII] A nuclear power plant includes a nuclear steam generator 1 and a superheater 2. The capacity of the superheater is greater than that of the present steam generator to allow for subsequent improvements in reactor technology, and the steam flow is supplemented by atomizing water into the steam during superheating, e.g. at 4 1  and 4 2 . The heating arrangements for the superheater have a heating capacity capable of superheating the steam output from the present nuclear steam generator together with an additional heating capacity sufficient to provide for the evaporation and superheating of the atomized water. The latter capacity is adequate to superheat a specified overload output from the improved reactor.

Title: Gas turbine by-pass jet engine
Inventor: OLDFIELD THOMAS ALFRED
IPC: F02K1/38
Filed: 1960-08-02
Abstract: 910,178. Gas-turbine jet engines. ROLLS-ROYCE Ltd. July 26, 1961 [Aug. 2, 1960], No. 26778/60. Class 110 (3). A gas-turbine jet engine of the by-pass type comprises a jet pipe, reheat combustion equipment mounted within the jet pipe, a by-pass passage disposed around the jet pipe, a valve controlling flow of by-pass air from the bypass passage, ducting disposed on the downstream side of the valve and through which the by-pass air may flow into the jet pipe for mixing therein with the turbine exhaust gases, and means for moving the valve between at least two positions in the first of which at least the greater part of the by-pass air flows through the ducting and into the jet pipe and in the second of which it is prevented from so doing. In the engine shown, reheat fuel ring manifolds 20 and annular flame stabilizing troughs 22 are disposed within the jet pipe 15 and an annular by-passage passage 16 is disposed outside the jet pipe, a series of angularly spaced apart ducts 23 being disposed at the downstream end of the by-pass passage, the ducts 23 being shaped as shown in Fig. 6, and by-pass air passing therethrough to mix with the turbine exhaust gases in the jet pipe. The spaces between ducts 23 are closed at the downstream ends so as to allow by-pass air to discharge through the annular space 24<SP>1</SP> outside the jet nozzle. A ring valve 26 is disposed at the upstream end of the ducts 23 and is formed with apertures 28, angular movement of the valve causing the apertures 28 to move into alignment with the ducts 23 or with the spaces therebetween. The ring valve is provided with tapering baffles 27 at its upstream face which guide the by-pass air to the apertures 28. The ring valve is rotated by means of a motor 32 and pinion 30 controlled by lever 41. When reheat is not in use the ring valve is disposed so that the apertures 28 therein are aligned with ducts 23 whereby by-pass air passes through the ducts to mix with the turbine exhaust gases in the jet pipe. When reheat is in operation, the ring valve is disposed so that the ducts 23 are blanked off and the by-pass air then passes through the spaces between the ducts 23 and discharges through the annular passage 24. A portion of the by-pass air passes through the annular spaces 33, 35 and duct 36 to the inner surface of the jet nozzle 37 for cooling purposes. A variable area nozzle having pivoted flaps 37 is indicated but this feature is not essential to the invention.

Title: Improvements in mechanisms controlled by light
IPC: B07C5/342
Filed: 1929-09-06
Abstract: 335,714. General Electric Co., Ltd., and Campbell, N. R. Sept. 6, 1929. Separating by electrical apparatus controlled by selenium and like cells. - A light-controlled relay of the kind in which two balanced photoelectric cells are energized to move say a conveyer belt to one side or the other, so as to sort out objects into two classes according to their colouring, is characterized by the provision of means whereby, when the controlling light-ray is not of the proper intensity to move the conveyer definitely to one extreme position or the other it is caused to alternate between the two positions with sufficient rapidity to enable a third sorting channel to be made available for objects of an intermediate colouring. As shown the main controlling-ray from a source 3 falls upon an object 1 to be sorted and upon a second object 2 of standard colouring. The reflected light passes to two cells 4, 5. Electromagnets 11, 9 thereupon attract armatures 13, 15 to swing the conveyer carrying the objects to be sorted either to the right or left according as the intensity of the light reflected from 1 exceeds or is less than the light reflected from the standard object 2. According to the invention an auxiliary source of light 17 is provided together with a screen 16 which is arranged to be moved to right or left by armatures 12, 14 controlled by further electromagnets 8, 10 in the circuits of the cells 4, 5. When an object of intermediate colouring causes the armature 13 to be moved momentarily to the left, the armature 12 similarly displaces the screen 16 to the left, and thus allows further light from the source 17 to be reflected by a mirror 20 on to the cell 5. This reverses the initial movement to the left, and starts a movement to the right. In consequence the screen 16 now exposes the mirror 19 to the source, 17, and stimulates the cell 4 so as to restore the initial direction of movement. In this way the conveyer is caused to alternate continuously between the two definite extreme positions, so long as the object of intermediate colouring is under survey by the main source 3. This movement, may be utilized to provide a third sorting channel for such objects. The auxiliary light ray 17 may be derived from the main source 3. Or the screen 16 may be oscillated by the armatures 13, 15, or by some independent mechanism, such as a motor.

Title: An improved method of and apparatus for casting flowable material into moulds
IPC: B29C45/46
Filed: 1946-09-16
Abstract: 618,689. Casting-machines. ARNOLD, C. (Lester Engineering Co.). Sept. 16, 1946, No.. 27769. [Class 83 (i)] After making a piston or other article by forcing magnesium, aluminium, zinc or other fluid or plastic material from a pressurechamber through a gate and into a mould, an additional amount of the material is forced into the mould during the cooling of the said article by contracting the length of, or applying pressure to metal in, the gate. A charge of fluid or plastic material is placed in a chamber 11 and forced by a plunger 10 into the cavity 24 of a water-cooled mould 3 with a cooled core 25. When the mould is full the material begins to solidify and the pressure therein rises and becomes sufficient to force back a plunger 33 against the resistance to the discharge of fluid in the cylinder 36 through an adjustable relief valve FC. This causes a shortening of the gate part 34 to supply material to the mould to make up for shrinkage. A suitable alloy is one containing 90 per cent of magnesium, 9 of aluminium, and 1 of zinc, which, when cast by the improved process, has a greater density and tensile strength than when cast by the ordinary die-casting process. The part of the gate subject to the greatest wear is formed as a replaceable insert 32.
