Title: Improvements in refrigerating apparatus
IPC: F25B9/00
Filed: 1951-10-05
Abstract: 705,718. Refrigerating. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 5, 1951 [Oct. 9, 1950], No. 23222/51. Class 29 [Also in Group XXVII] A combined hot gas engine and refrigerator working on the reversed hot gas engine cycle comprises a hot space 84 communicating through a heater 85, regenerator 86 and cooler 87 with a cold space 91, and a freezing space 96 communicating through a freezer 95, regenerator 94 and cooler 93 with the cold space 91, the total volume of the working space being varied by a piston 92 and displacers 81, 83 with constant phase differences calculated in accordance with a formula set out in the Specification and claims. The gas in the cold space 91 is compressed, flows through the regenerator 94 to the freezing space 96 and expands therein due to the movement of the displacer 83, thus extracting heat from the chamber 100 to be cooled. The gas is then driven back by the displacer to the cold space 91. A burner 98 heats the space 84 and the hot gas passes through the regenerator 86 to the working piston 92 to supply the necessary energy. The crank case is closed with no lead-through devices for the shaft 97. The piston 92 and displacer 83 can move in phase and can be replaced by a differential piston, or two differential pistons may be: used. The energy supplied by the hot gas cycle may be sufficient to drive a fuel pump for the burner 98 and an air compressor. Fig. 8 :shows a modification comprising a freezing space 133 cooling a refrigerating chamber 146 and communicating through a freezer 143, regenerator 142 and cooler 141 with a cold space 140, 139. The: hot space 135 communicates by a heater 136 heated by a burner 145, regenerator 137 and cooler 138 with the cold space 140, 139.

Abstract: 747,105. Laminated materials. HANSEN, H. L. M. Aug. 24, 1953 [Aug. 25, 1952], No. 23265/53. Class 140. Laminated material comprising two sheets of thermoplastic synthetic resin such as polyvinyl chloride or polythene locally united to form gas-filled pockets is made by forming a tube of thermoplastic synthetic resin by extrusion and feeding said tube between tools having elevations or cams for locally pressing the walls of the tube together, while at the same time blowing air or gas into the tube, the tools being close to the extrusion nozzle so that the tube walls are sufficiently warm to effect uniting and the tools being arranged to cool the material so that the uniting is maintained when the tube leaves the walls. As shown, Fig. 4, the extruder 4 has an annular mouthpiece 5 into which air or gas is blown through a pipe 6 and a central passage 7. The extruded tube 8 is passed between rollers 9 and 10 which unite the walls locally. Each roller consists of a cylindrical drum 11 having elevations 12 on its outer surface and mounted for rotation on a stationary tube 13 having a longitudinal slot 14. At the bottom of each recess between the elevations 12 a passage 15 is formed. Suction is effected through tube 13 and passages 15 as the drum 11 revolves, thus giving the air pockets the desired shape. The tube 13 also is formed with a longitudinal passage 16 through which compressed air is introduced to assist the material in leaving the roller after the uniting operation. Roller 9 may be constructed in the same way, or may be smooth if it is not necessary to have a high amount of air filling in the pockets. A modification employing endless belts constructed on the same principle as the rollers is described.

Title: Improvements in or relating to controlling aircraft
Inventor: BRITT JACK
IPC: B64C29/00
Filed: 1953-08-25
Abstract: 806,030. Controlling jet-propelled aircraft. ROLLS-ROYCE Ltd. Aug. 3, 1954 [Aug. 25, 1953], No. 23494/53. Class 4. [Also in Group XXVI] An aircraft of the kind in which control is effected by jets of gas emitted from the aircraft, comprises an auxiliary jet nozzle arrangement including at least one nozzle connected to a conduit to be fed with gas under pressure from a pressure source, the nozzle being of variable area and the thrust developed by the jet of gas flowing from the nozzle being controlled by variation of the area of the nozzle. In the aircraft shown in Fig. 1 the gas turbine engines 14 are adjustably mounted so that their jet pipes 15 are vertical for take-off and at, say, 30 degrees to the vertical for level flight. Air is tapped off from the compressors of the engines and led through a distribution pipe 22 and conduits 23, 24, 25 to downwardly-directed nozzles 26, 27, 28 ; these nozzles are all similar and comprise a valve casing 30, Fig. 3, connected to one of the conduits 23, 24, 25 and having a downwardly-facing outlet 32, and a pair of pivoted flaps 29. The rear of each flap 29 is hollow and is open to a space 30a which is vented round the flap hinge to the pressure of the gas within the nozzle so that the flap is pressure-balanced. Each nozzle is operated by an electric actuator in response to control signals produced either manually or by an automatic pilot or by a combination of the two. The two flaps 29 of each nozzle are geared together for simultaneous operation and are arranged so that under equilibrium conditions each nozzle is one third open ; the control system is preferably arranged so that the total lift from the nozzles remains constant. Fig. 5 shows an automatic pilot for controlling the areas of the nozzles. A triangular plate 40 is mounted in a gimbal structure stabilized by an air-driven gyroscope 39 ; the casing 41 is fixed relative to the aircraft and has a domed portion 41a relative to which the plate 40 moves on change of attitude of the aircraft. The domed portion 41a is provided with three nozzle pieces 42 each having formed in it a row of, say six, jets 43 fed with compressed air. Each jet blows on to a corresponding electric switch, except when intercepted by the plate 40. When the triangular plate 40 moves from the equilibrium position, various of the electrical switches are operated and are made to act, through a servo-mechanism (not shown), to cause the electrical actuators to adjust the nozzles 26, 27, 28 to cause a control moment to restore equilibrium. The casing 41 may be manually adjustable to provide for manoeuvring the aircraft, or alternatively the gyroscope 39 may be over-ridden by a manual control 51. In an alternative arrangement, the aircraft is provided with two control nozzles, one at each wing-tip, of the form shown in Fig. 9 ; the nozzles are arranged vertically to produce a net upward or downward thrust according to the position of the valve 67 which adjusts differentially the areas of the outlets 65, 66.

IPC: F16T1/16
Filed: 1958-07-22
Abstract: 893,115. Steam traps. CRANE CO. July 22, 1958, No. 23501/58. Class 64(2) Condensate, e.g. from a separator, passes from an inlet 4 into a chamber 38 and through a cruciform arrangement of passages 14 in a cage member 9 and by way of a vertical passage 18 it contacts a loose-plate valve 24 which it lifts to pass to an annular groove 21. From this groove, in the embodiments shown, the condensate flows down through a pair of diametricallyopposed ducts 31 in the cage member to a discharge chamber 33 with an outlet 7, e.g. to a condensate return line. A cap 26 on the cage member 9 forms an inner chamber 25 containing loosely the valve plate 24 and bears ribs 28 for facilitating gripping of the cap when it is tightened in position. When steam enters or is formed in the inner chamber 25 it closes the valve plate 24 down on to the lands surrounding the end of the passage 18 and the groove 21. In one modification, Fig. 3 (not shown), there is an extra inlet and an extra outlet, one on each side of the trap casing, the inlet communicating directly with the outer chamber 38 and the outlet receiving condensate through a duct (in the casing wall) leading from the discharge chamber 33. In a further modification, Fig. 4 (not shown), the annular groove 21 does not constitute part of an outlet passage, since there are no ducts 31, but a short tube coaxially located in the passage 18 has a bore extending down as an outlet through the cage member 9 to the discharge chamber 33. The valve plate seats on the top of this tube as well as on the lands around the groove and when it is unseated the condensate flows radially inward from the top of the passage 18 to the central tube. Specification 755,178 is referred to.

Abstract: 1,145,272. Separating benzene or alkylbenzene crystals. IMPERIAL CHEMICAL INDUSTRIES Ltd. 27 May, 1966 [3 June, 1965], No. 23742/65. Heading C5E. Crystals of benzene or an alkylbenzene aro separated from admixture with a first liquid having a density at least 10% less than the crystals, e.g. a crystallization mother liquor, by contacting the mixture with a liquid substantially immiscible with the first liquid and having a density at least 2¢ % less than the crystals and 2¢% more than the first liquid, thus forming, without loss of material from the system, a system in which crystals of benzene or alkylbenzene are separated by the immiscible liquid from at least part of the first liquid, and separately recovering the first liquid and the benzene or alkylbenzene of the crystals. Suitable immiscible liquids are water, water/alcohol mixtures and water/ketone mixtures. A surfactant may be present. The immiscible liquid is preferably cooled to the same temperature as the mixture before contact therewith. Alternatively, the immiscible liquid may be sufficiently cold to cause crystallization of benzene or alkylbenzene from a solution thereof, thus forming the crystal/liquid mixture to be separated. During the contacting with the immiscible liquid the mixture may be subjected to centrifugation and/or sonic vibration. The final separation of the crystals may be conventional, e.g. by filtration or decantation of the upper liquid layer, followed by melting of the crystals and subsequent decantation from remaining liquid. In examples, p-xylene is recovered from p-xylene/o-xylene mixtures or from mixtures of all three xylenes with ethylbenzene.

Abstract: 214,548. Verschoyle, W. D. Sept. 24, 1923. Stoppers with valves.-Relates to closing caps, nozzes, and self-closing valves for collapsable tubes. The valve shown in Fig. 1 comprises a rubber diaphragm 17 secured by cement or the like around the flat edge 16 at the mouth of the tube 11, and provided with a minute central perforation or slit. The screw cap 14 is provided with a convex, hollow, domed portion 19 adapted to be perforated, or to be cut off by a knife, to permit the contents to be extruded without removing the cap. In a modification, the diaphragm is secured in position by providing it with a dovetailed marginal flange for engagement with a corresponding groove around the neck of the tube. Fig. 3 shows a valve comprising an unperforated diaphragm 17 secured at one part only of its margin by means of a wire, staple 25 passing through the diaphragm and through holes provided in the neck of the tube. It is necessary'to remove the cap 14 to allow this valve to operate. In another modification, shown in Fig. 4, the neck 12 of the tube is permanently closed at its upper end 28 and is provided with a lateral orifice 29. A septum 26 of rubber or like tubing is tightly received in a conical seating 27 around the neck of the tube and covers the lateral orifice 29. When the cap 14 is removed, compression of the tube forces the contents through the orifice and compels the septum 26 to yield and permit extrusion.
