Filed: 1952-02-19
Abstract: 716,145. Jet propulsion plant: gas turbines. LAGELBAUER, E. Feb. 19, 1952, No. 4402/52. Class 110(3) An aircraft jet propulsion engine comprising a prime mover driving an air compressor part of the discharge of which is supplied to the prime mover and part direct to a jet propulsion nozzle and a second prime mover, driven by exhaust gases from the first prime mover, driving a ducted fan, has means for varying the ratio of the amount of air supplied to the first prime mover to that passing direct to the jet propulsion nozzle. Air compressed in a low pressure axial-flow compressor 16 is passed through a cooler 29 to a high pressure axial-flow compressor 17 which feeds a combustion chamber 18. The gases for this combustion chamber pass through a high pressure turbine 15 driving the compressors 16, 17 to a low pressure turbine 13 driving a ducted fan 11 which exhausts through a jet propulsion nozzle 33. A part of the compressed air from the low pressure compressor 16 is passed through a valve 23 and a duct 24 to cool the blades of a turbine 15 after which it is mixed with the turbine exhaust gases and used in the turbine 13. A valve 19 diverts another portion of air from the compressor 16 through a duct 20 direct to the propulsion nozzle 32. A heat exchanger 21 transfers heat from the turbine exhaust gases to this air. Compressed air from the outlet of the cooler 29 is passed through a valve 28 and duct 27 to the casing 31 around the turbine 13 to cool it. This air is then mixed with the air passing through the duct 20. By operation of the valves 19, 23 and 28 it is possible to control the output of the turbine 13 and the speed of the ducted fan 11 to the various conditions of flight.

Patent GB-607993-A (GB)
Title: Production of artificial filaments and other articles
IPC: D01F2/28
Filed: 1946-02-13
Abstract: Artificial filaments, foils, and similar materials are obtained by extruding a solution of an organic acid ester of cellulose having a low acyl content, in a water-miscible solvent containing not less than 40 per cent by weight of water, through a shaping device into an aqueous coagulating medium containing an ammonium salt of a lower aliphatic acid and a low proportion of a water-miscible organic solvent for the cellulose ester.  Cellulose esters having an acyl content of 1.5 to 1.8 acyl radicals per glucose unit of the cellulose molecules, i.e. in the case of cellulose acetate of 40 to 45 per cent acetyl value calculated as acetic acid, may be used.  Instead of cellulose acetate, there may be employed cellulose propionate, butyrate, aceto-propionate, or acetobutyrate.  In the case of cellulose acetate, the coagulating bath may contain 5 to 25 per cent of an ammonium salt of a lower aliphatic acid such as formic or acetic acid.  The bath may be maintained at 5 to 15 DEG  C.  The spinning solution may contain 8 to 18 per cent of cellulose acetate in aqueous acetic acid containing at least 40 per cent of water.  The solution may be extruded at 20 to 50 DEG  C. into the cold spinning bath.  The coagulated filaments may be stretched up to about 200 per cent of their original length simultaneously with their formation and while they are still in a softened condition.  If higher degrees of stretching are required the filaments may be further softened by the action of steam or hot water or a liquid or gaseous organic solvent, and then stretched.  A solution of cellulose acetate ripened to the desired acetyl value may be extruded directly into the coagulating bath.

Abstract: 625,668. Welding feet on letters &c. SCHNEIDER, J., and SCHNEIDER, H. Feb. 18, 1946, No. 5052. [Classes 83 (ii) and 83 (iv)] In welding feet to dial plates, letters, &c., the dials &c. are clamped on a movable table and the feet are clamped in at least two percussors, each supplied with current from an electric condenser. The dials 2 may be placed on a table 4 provided with clamps 5 and ejector 6, and rotatably mounted on an axis 7 carried by a pair of columns 9, a pair of stops being provided to determine the upper and lower positions of the table. Within the casing 3 are mounted columns 9a angularly adjustable by worm-gear 11. Laterally adjustable in the columns 9a by screws 13 are slides 12 in which are mounted hollow rods 14 having chucks for carrying the feet 1. These rods are operated by adjustable springs 18 to effect a percussive weld, being retracted by levers 23 operated by push buttons 22 and held in this position by stops 24 engaging behind the armatures 25 of electromagnets. The rods and dials are connected to the opposite sides of variable condensers provided with hand-operated switches for connecting them either to the current supply or to the work, the electromagnets being energized when the switches are moved to connect the condensers to the work. With the dial placed in the table and the table rotated into operative position, the rods 14 pressed down to open the chucks against the action of springs 50 and to compress the springs 18, the feet 1 are inserted in the chucks and the rods held by the stops 24 engaging the armatures 25. When the switches are operated the condensers are connected to the work parts and the electromagnets are energized to withdraw the armatures so that the springs 18 force forwards the rods for the feet to engage the dial and the condensers are discharged to effect the welds. In another form the table 4, Figs. 4 and 5, is carried by a slide 40 moved by a hand lever 22 through link 22d and lever 22e along a guide 3c to set the table in operative position, determined by an adjustable screw 4a. The slide is provided with clamping dogs 5 on spring-controlled rods 5a which are provided with segments 5b having helical grooves 5c so that the rods may be rotated by engaging a finger 7a on the slide 40 to bring the dogs over the table. The rods are normally held against a stop 3d on the guide 3c, passing through a slot 7b in the slide 40. Laterally adjustable slides 12 carried by adjustable turrets 9a receive spring-pressed feet-carrying rods, and when the hand lever 23 is operated to bring the table into operative position, an operating fork 16 is withdrawn by a spring-returned lever 22b controlled by the cams 22a. on the lever 22 so as to allow the chucks to close on the feet 1 by the action of springs 50, Fig. 6. Welding is effected as in previous form. The table may be movable about an axis instead of on a slide and the lever 22 may be electrically controlled.

Title: Improvements in or relating to means and methods of treating water
Inventor: WHITE PERCIVAL ALBERT FREDERIC
IPC: G21F9/10
Filed: 1951-03-02
Abstract: 790,474. Purifying water and trade effluents. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 18, 1952 [March 2, 1951], No. 5065/61. Classes 46 and 111. A method of removing radioactivity from water contaminated therewith comprises forming a precipitate from tannic acid and a soluble calcium compound, maintaining the precipitate in suspension in the water under alkaline conditions for from 3 to 20 hours and then separating the precipitate with its content of radioactivity from the water. Aqueous radioactive effluent to be decontaminated prior to disposal or re-use flows through a valve 2 into an open vessel 3 and thence by a conduit 5 to a mixing flume 6 where tannic acid and a soluble calcium compound (e.g. the hydroxide) are introduced at 7 and 8 respectively. The valve 2 is adjusted to maintain a slight overflow of liquid back to the supply by means of device 4, so that the vessel 3 maintains a constant head of liquid for treatment. A precipitate of calcium tannate is formed by the reaction, and is maintained in suspension in the liquid by stirrers 14 in a holding tank 13, to which the mixture passes via a #H cell 10. The rate of flow of incoming liquid is so adjusted in relation to the volume of the vessel 13 that the liquid takes from 3 to 20 hours (preferably from 3 to 5 hours) to traverse the vessel. The mixture in tank 13 must be alkaline and for this purpose ammonia or further calcium hydroxide may be added, e.g., in the flume 6, preferably in amount to maintain the pH at from 8À5 to 9. From tank 13 the mixture passes to a continuous settling vessel 16 where suspended matter, bearing nearly all the radioactive matter originally present, settles and is withdrawn at 19. Clear effluent is withdrawn via a filter 21 by a pump 23 and discharged at 24. Salts, e.g., ferric chloride or other iron salts, and sodium phosphate, may be added with the reactants, and the liquid being treated may be acidified to a #H of approximately 4 prior to the vessel 3. The ratio of tannic acid to liquid treated may be as high as 100 parts per million but 50 parts per million is preferred.
