Title: Centrifugal gas compressors
IPC: F04D29/46
Filed: 1964-05-05
Abstract: 1,006,147. Centrifugal compressors. WESTINGHOUSE ELECTRIC CORPORATION. May 5, 1964 [May 15, 1963], No. 18610/64. Heading F1C. A centrifugal compressor comprises a rotor having radial-flow blades, an axial-flow inlet passage extending to the rotor and containing adjustable spin vanes, and a diffuser extending radially from the vicinity of the blade tips and comprising a space formed between fixed wall and a movable wall, and means for adjusting the spin vanes between fully open and fully closed positions and including a member for moving the movable wall towards the fixed wall when the spin vanes are being adjusted towards and are near the closed position. Spin-inducing vanes 12 within a convergent axial inlet passage 11 are each carried by a pivot pin 14 carrying an arm 15 having a pin 16 engaging an annular groove in an annular piston 41. When the compressor output is to be reduced, oil under pressure is supplied through passages 52, 50 to move the piston 41 to the left and thereby turn the vanes 12 towards the closed position. When the vanes 12 are nearly closed, the piston 41 comes against a ring 56 as shown and moves the latter and, with it, a diffuser ring 30 to the left to reduce the width of an annular diffuser 26 as the vanes are moved towards the closed position. This reduction increases the velocity of the gas flow through the diffuser and thereby prevents stalling. When the compressor output is to be increased again, oil under pressure is supplied through passages 49, 48 to move the piston 41 to the right and thereby open the vanes 12. The gas pressure within the diffuser moves the diffuser ring 30 to the right to increase the diffuser width.

Title: A camera loading two films
IPC: G03B19/06
Filed: 1963-05-10
Abstract: 980,661. Cameras. H.DOMNICK. May 10, 1963 [May 11,1962], No. 18611/63. Heading G2A. In a camera in which either of two films both contained therein may be exposed, each film is windable from a stationary spool on to a movable take-up spool, each take-up spool being movable independently of the other so as to dispose that particular film in the image field of the objective. In the form shown, one film 11 unwinds from spool 9 on to take-up spool 15, and the other film 12 from spool 10 on to spool 16. The central part of the camera comprises an exposure chamber 3 behind an objective 2, shut off by hinged flaps 17, 18 from the magazine chambers 7, 8 containing the films. To expose one of the films, the movable spool (e.g. spool 16) is pulled across by means of a handle 32 to occupy the position 16<SP>1</SP> (which may at the same time cock the shutter). The unwound portion of the film now lies against the back wall 4 of the camera, held there by the flaps 17, 18, which return to the position of Fig. 1 under spring loading after the spool 16 has passed them. Fig. 3 shows in more detail the mounting of spool 16, which is held in a sliding mount 21 movable along a roller track 22, 23. Mount 21 is attached by a tape 25 to a spring drum 26, which retracts the spool 16 back from position 16<SP>1</SP> when allowed to do so. The means retaining the spool in position 16<SP>1</SP> may be released automatically by the shutter release. Spool 16 carries a ratchet which can be engaged by a pawl, normally out of engagement but engaged by the action of handle 32 as spool 16 is pulled across. This prevents pool 16 from turning, so that fresh unexposed film is drawn off spool 10. As spool 16 returns to its original position, it turns clockwise to wind up the exposed film.

Abstract: 714,807. Safety devices for firearms. HUSQVARNA VAPENFABRIKS AKTIEBOLAG, July 24, 1952, No. 18806/52. Class 119  A firearm with a rotatable and longitudinally movable breech-bolt, has a safety member mounted on the breech-bolt casing and laterally of the sear 2. this member being manually displaceable in a longitudinal direction so that it can be moved to and from a position where it co-operates with a pin 7 on the rear end of the sear to lock the latter against firing movement. In Fig. 1 the trigger I is pivoted at 3 to the sear 2 which is povited at 5. The safety device is in two parts 8, 18, of which the part 8 is movable by hand back and forth and is made to occupy two positions by the co-operation of a pin 11 on the said part with the V-portion 12<SP>1</SP> of a leaf spring 12. A slot 10 in the part 8 receives a pin 19 on the part 18 so that the latter follows the movements of the part 8. When the two parts are in the rear position shown, the hooked forward end of the part-18 engages a pin 7 on the sear and thus prevents the latter from moving when the trigger is pulled. In a modification, Fig. 3, the safety device is in one piece and has an extension 21 for engaging the pin 7 on the sear when moved to its forward position. The device 8 carries a pin 23 which moves in a bore 25 in the part 4 of the bolt casing and can project into a bore 26 in the bolt handle 27, thus keeping the handle in its downward position until the device 8 is moved to the rear.

Patent GB-795181-A (GB)
Title: Higher fatty alcohols
Filed: 1956-06-19
Abstract: Higher fatty alcohols are produced from fat by contacting the fat with a higher fatty alcohol in the presence of a transesterification catalyst and at a temperature in the range 300-650 DEG  F., the excess added higher fatty alcohol, glycerine and a fraction rich in a higher fatty acid ester of the added higher fatty alcohol being thereafter separated from one another, the ester fraction then being contacted with hydrogen at a temperature of 400-700 DEG  F. and a pressure of 500-5000 lb./sq. in. in the presence of a hydrogenation catalyst; and at least a major proportion of the hydrogenation reaction product being thereafter contacted with further quantities of fat under the same transesterification conditions.  The "higher" fatty acids and alcohols referred to are those containing 10 or more carbon atoms. The glycerine and excess alcohol may be separated from the higher fatty acid ester fraction by fractional distillation or water washing.  Preferably a stoichiometric excess of higher fatty alcohol over the fat is employed.  Suitable transesterification catalysts are, for example, litharge; tin, cadmium, zinc and their compounds; sodium ethylate and sulphonic acids.  Suitable hydrogenation catalysts are, for example, copper chromite; cadmium, silver, tin and their oxides; the oxides of zinc, chromium, manganese and magnesium; and the ruthenium-containing hydrogenation catalysts. In an example, tallow containing an ester interchange catalyst, e.g. litharge, is heated with tallow alcohol, produced in a subsequent step of the process; glycerine and excess tallow alcohol are distilled off; the tallow alcohol-tallow acid ester is collected and treated with hydrogen in the presence of a catalyst, e.g. copper chromite, to give the tallow alcohol.ALSO:Glycerol is obtained as a by-product in a process for the production of higher fatty alcohols from fats in which a higher fatty alcohol is contacted with a fat at a temperature of 300-650 DEG  F. in the presence of a transesterification catalyst such as litharge.  In addition to the glycerol so formed there is also obtained a fatty acid ester of the higher alcohol which is subsequently submitted to catalytic hydrogenation to give higher fatty alcohol, a major proportion of which is contacted with further quantities of fat.  The "higher" alcohols referred to are those containing 10 or more carbon atoms.

Abstract: 727,911. Cold separation of air. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 14, 1953 [July 28, 1952], No. 19062/52. Class 8 (2). A process for liquefying and separating a gas mixture A, Fig. 1, e.g. air comprises passing a first portion c of precooled compressed air to an intermediate point of a distillation column 2 having a heating coil 3 at the base thereof and passing a second portion d of precooled compressed air through an adiabatic expansion engine, e.g. a turbine 7 and feeding it to a condenser 6 connected by a duct 4 to the top of the column 2 and returning the gas so condensed 'back to the column through a duct 5 to act as reflux. The heating coil 3 is traversed by a portion b of the precooled compressed air which is returned through the precooler 1, a heat exchanger 9 cooled by a vapour compression refrigerator 10, and an exchanger 11 cooled by nitrogen gas from the top of column 2 ; the flow through the coil 3 being controlled by a by-pass valve 35 and the so cooled air being fed to the portion d entering the turbine 7. Oxygen-rich liquid air is obtained through a valved duct 26 on opening a valve 25 and closing valves 15, 20, 21 and substantially pure liquid air is obtained from a vessel 16 on opening the valve 15 and closing valves 20, 21, 25 thus putting the column 2 out of action. Liquid nitrogen alone is obtained by opening valves 15, 25 and closing valves 20, 21, and on opening the valve 20 gaseous oxygen may also be obtained at an outlet 24. Liquid oxygen and gaseous nitrogen are obtained at outlets 26, 24 by opening valves 21, 25 and closing valves 15, 20. An argon-rich gas is obtained at an outlet 28 and a neon and helium-rich gas at an outlet 29 at the top of the condenser 6. In a modification further purification of liquid nitrogen is obtained by dividing the condensate part of the condenser 6 into a gas tight chamber 30, Fig. 2, which is connected by the duct 5 to the column 2 and by a nitrogen-rich gas duct 34 to a gas tight chamber 31 where further purification occurs and substantially pure nitrogen gas leaves by a duct 29 or a valved duct 38 of the chamber 30.
