Title: Multiple-feed spray guns
Inventor: EDWARDS HARRY
IPC: G05D11/13
Filed: 1958-09-02
Abstract: 856,191. Mixing fluids in flow in proportions. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 4, 1959 [Sept. 2, 1958], No. 28148/58. Class 86 [Also in Group XXIX] In an apparatus for supplying two or more liquids in predetermined proportions of the kind using coupled metering pumps, the speed of the pumps is controlled electrically by one or more switches mounted on the spray gun or other delivery appliance. In the Figure K is a switch actuated by the trigger of the spray gun E and energizing the solenoid N which controls the valve O to admit air from a supply U to an air motor A which drives the metering pumps B, G (which are geared together at H) to supply liquids through the flexible pipelines D, J. A further depression of the spray gun trigger actuates the switch P operating the solenoid S and valve T through which an additional supply of air is admitted to the motor A. The apparatus is primarily directed towards forming polyurethane foam, in which case one liquid may be polyisocyanate and the other a mixture of the polyester with catalyst and additional materials.. Predetermined total quantities may be metered, as when filling a cavity, by using a dispensing head with a timing switch or preferably by controlling the total number of revolutions of the pumps by a relay actuated by a revolution counter. A series of different quantities may be metered by using uniselectors. The electrical controls may also be arranged to pass a current of cleaning air through the mixing chamber, automatically or otherwise. Specification 759,602 is referred to.

Abstract: 1,084,754. Compressors. AMERICAN MOTORS CORPORATION. July 2, 1965 [Sept. 21, 1964], No.28207/65. Heading F1N. [Also in Division F4] A reciprocating refrigerant compressor 18 has a shaft 26 driven by an electric motor 22 and is resiliently mounted within an hermetically sealed housing 14 on three coiled compression springs 64 having ends provided with closely wound turns which surround posts 62, 58 formed, respectively, on the housing 14 and on the compressor block 50. The housing 14 is filled to a level 80 with lubricant which enters an aperture 94 in a thrust plate 90 to pass into three longitudinal bores in the shaft 26.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1938-09-29
Abstract: 519,141. Refrigerating. ELECTROLUX, Ltd. Sept. 29, 1938, No. 28363. Convention date, Sept. 30, 1937. [Class 29] Absorption system.- In a continuous-cycle inert-gas system a part of the liquefied refrigerant is periodically accumulated out of circulation in a store and then suddenly discharged to the inert gas system to stop evaporation for a defrosting period, or to a sump in the evaporator to displace solvent liquid therefrom, or to the rectifier or other part to effect replenishment of liquid therein with anti-corrosion media. Condensate from the part 15, Fig. 1, of a double condenser 16, 15 flows at 80 into a U-tube 81 and accumulates slowly until it overflows as a stream down a small' bore tube 82 into a larger bore tube 84 connected to the poor inert gas conduit 51 from the absorber 12 to the usual gas heat exchanger 26. The refrigerant evaporates and changes the density. of the gas in conduit 51 so that gas circulation to, and evaporation in, the evaporator ceases. Warm refrigerant vapour may find its way into the evaporator and effect defrosting. The liquid seal in the U-tube 81 reforms and refrigerant in a store 40 in the low temperature part 18 of the evaporator is available for immediate production of cold. The U-tube seal and store may be supplied from'a separate condenser below the double condenser 15, 16. In a modification shown in Fig. 2 liquefied refrigerant flows into a conduit 90, 91, 94, 95 from the usual conduit 31 which supplies the evaporator at 37. The part 91 of the, conduit receives heat at 92 by metallic conduction or otherwise from the hot expulsion pipe 14 of the generator 10, and refrigerant is vaporized therein and recondensed in the part 94 of the conduit, finally overflowing the part 95 into the conduit 84. The heat transfer at the point 92 may be varied as by an air gap closable by a removable metal plug &c. and may be such that a period of several hours or days may be necessary to prime the overflow 95. The condensate from the overflow may be ted to a hot part of the apparatus and the evaporation be utilized to lift or displace solution rich in anti-corrosive medium to any desired part. According to another arrangement the evaporator store 40 may be connected with the overflow and the refrigerant be led therefrom to an auxiliary boiler, the hot vapour from this boiler being led to the evaporator to defrost it, until the auxiliary boiler is empty.

Abstract: 537,469. Agitating liquids in flocculating chambers. DORR CO., Inc. Oct. 23, 1939, No. 28484. Convention date, Oct. 21, 1938. [Class 86] [Also in Group I] Agitating blades in a flocculating chamber are arranged with the blade faces at an angle to the direction in which they move and co-operate with stationary blades to deflect the liquid in places at right angles to the normal flow of the liquid through the chamber. In the combined flocculation and settling apparatus shown the liquid is supplied to an inner flocculation chamber 41 through a vertical pipe 7 and apertures 8 and agitated therein by vertical blades 60 on a rotary support. The blades are arranged at an angle to their direction of motion so that they direct the liquid inwardly. The blades 60 pass between stationary vertical baffles 52 which are also arranged to direct the liquid inwards. The chamber 41 and the baffles 52 are supported from a truss 14 extending across the top of the settling tank 1. The rotary support for the blades 60 comprises radial arms, 72, 73, attached to a drum 66 supported by a bearing 68 and rotated by a motor 69. The drum 66 has apertures 22 corresponding to the apertures 8 for the entry of the liquid. The liquid passes from the flocculating chamber to the settling-tank through an annular passage between the outer edge of a plate 46 attached to the pipe 7 and the inner edge of an inclined annular plate 45 which forms a bottom for the chamber 41. Sludge settling in the tank is directed to a sump 12 by scoopers 21 attached to the pipe 7 which is supported by a shaft 27 rotated by mechanism 28.

Abstract: 334,722. Armstrong, J. J. V., (Badischen Maschinenfabrik & Eisengiesserei). Sept. 21, 1929. Cleaning.-Jet tubes for cleaning castings are mounted in the wall of a cleaning chamber so that they are adjustable longitudinally, vertically and laterally to direct the jet on to the desired part of the casting, mechanism being provided to hold the tube firmly in its position and to relieve the operator of the back pressure. In the form shown in Fig. 1 a cord 3 one end of which is attached to the jet pipe 4 while the other end carries a weight 5 passes over a roller 2 mounted on the outside of the chamber 1. When the jet is cut off the weight 5 falls and a flange 8 on the tube 4 abuts against the wall 1. Figs. 2 and 3 show the tube 9 held adjustably by means of a ball joint. Sockets 11, 12, attached to the chamber wall grip a ball 13 with extension 14, through a bore in which the tube 9 is inserted. In Fig. 2 the outer ends 15 of the extension 14 are conically tapered and slotted, a screw cap 16 with handle 17 being provided to hold the tube in any desired longitudinally displaced position. In Fig. 3 the extension 14 has a slit 18 in which an eccentric 19 with handlever 20 is pivotally mounted to clamp the tube 9. In these modifications the back pressure is taken up by the clamping means and transmitted through the ball joint to the wall of the cleaning chamber. A large aperture 21, Fig. 4, in the wall of the chamber is closed by a rotatable disc 22 formed with a radial slit 24 in which the clamping means 25 is displaceably mounted. Several of such apertures may be provided in the chamber walls in which the jet tube may be inserted as desired. Specification 315,446 is referred to.
