Patent GB-1361003-A (GB)
Title: Separation of a multiphase liquid-liquid mixture
IPC: B01D17/04
Filed: 1971-06-14
Abstract: 1361003 Magnetic separators AVCO CORP 14 June 1971 [15 June 1970 (2) 18 May 1971] 27835/71 Heading B2J [Also in Divisions C1 and C5] The figures illustrate an apparatus for separating a petroleum oil/water mixture to which a colloidal dispersion in oil of magnetizable particles has been added. The electromagnet 14 comprises an air or water-cooled copper tube 16 through which an electric current is passed from the cables 18 and 20. Magnetic steel fins 24 extend radially from the tube 16 to the wall of the vessel 12. The segment spaces between the fins 24 are loosely packed, either entirely or at spaced apart intervals, with magnetic steel wool or steel fabric 26. The oil/water mixture enters at 28 and is separated into a magnetic phase which collects near the tube 16 and enters the chamber 34 and a non- magnetic aqueous phase which collects neat the outer wall of the vessel 12 and is drawn off at 32. A magnetic levitation flow control valve 40 only allows flow out of the chamber 34 when the lower portion of the chamber is full.

Title: Improvements in or relating to circular knitting machines
IPC: D04B9/10
Filed: 1932-10-07
Abstract: 408,598. Knitting-machines. BENTLEY, P. A., GODDARD, J. H., MANGER, C. F., WAINWRIGHT, C. H., and BUSWELL, G. A., Komet Works, New Bridge Street, Leicester. Oct. 7, 1932, No. 27868. Addition to 301,350, [Class 74 (ii)]. [Class 74 (ii).] In a circular knitting-machine having two or more feeders, one, which feeds a main yarn and a plating yarn, is arranged so that immediately it moves from its feeding position towards its associated yarn trapper and cutter, its yarns cease to be knitted by the needles. A latch retarder engages the latch of each needle as the latter is descending and prevents its sudden closing. The machine shown has five feeders. The special feeding device consists of two parts 130, 132, Fig. 1, one feeding the main yarn, and the other the plating yarn. Their shanks slide in the end walls 136 of frame member 138, whilst studs 156, 157, carried on blocks 154, 155 adjustably fastened to the shanks, slide in slots 158, 159, formed in the top plate 140 of frame member 138. Either or both slots may have an inclined portion 160. Set screws 162, 164, adjustably limit movement to the left and movement of the shanks to the right may be adjustably limited by a single set screw 166, the blocks 154, 155, being arranged to overlap. The shanks are moved to the left by an arm 148 ; shock at the end of the movement is eliminated by spring loaded sleeves 150. The return movement is effected by springs 152. The inclined portion 160, causes axial rotation of the shank 134, and consequently allows vertical adjustment of the associated feeder end 130 of the needle. The cutting and trapping device (Fig. 3) consists of a flexible blade 174, notched at its end, and contained in a casing 176, closed by a bottom plate 178. The blade is projected by an elbow lever 180, registering in a slot in the blade and actuated by wire 184 and is retracted by a spring pressed plunger 185. The latch retarder consists of a hooked member 186, Fig. 4, adjustably secured in a holder 190 rotatably mounted on the inclined end of a post 192, and removable from the operating position by wire 196 against the action of a spring 194. The needle cylinders rotate in a counter clockwise direction as seen in Fig. 1, and the stitch cam is approximately under the feeders when in the feeding position. The other feeders 10 move to the left to their cutting and trapping devices 84 ; their dipping is controlled by studs 128 in cam-slots 124. Control units are shown at 210. Specifications 15008/00, [Class 74], 24290/12, 171,483, and 301,360, [all in Class 74 (ii)], are referred to.

Filed: 1921-10-21
Abstract: 189,618. Bolas, H., and Parnall, G. G. Oct. 21, 1921. Dash-pots; buffers.-A shock absorber for aircraft comprises a doubleacting oleo gear connected at one end to the fuselage of the aircraft and at its other end to the landing wheels &c., the gear having substantially equal piston areas for both forward and return strokes, a tubular rod connected to one piston of the gear, and an annular space in another piston and surrounding the tubular rod to act as a two-way valve. A cylinder 7 telescopes to a limited degree in a cylinder 6, and is provided with a piston 8 through which a hollow rod 12 passes, leaving a small clearance 11 around it. The rod 12 which is secured to the cylinder 6 carries a second piston 13 working in the cylinder 7, and the space opposite thereto and between the cylinders is closed by a stuffing- box 10 which in conjunction with the piston 13 forms a piston almost equal in area to the piston 8. In practice, oil flows through the clearance 11 and holes 15 in the cylinder to an annular space 16 and vice versa. The device may be used in conjunction with compression rubber shock absorbers 19, the whole constituting a shock-absorbing strut forming part of the undercarriage of the machine.

Classes 7(2) and 7(3) In an engine which can run cn heavy oil or petrol, the heavy oil is heated in a chamber 26, Fig. 1, on each cylinder in heat-exchange relationship with a precombustion chamber 25 provided with a sparking plug 25a and the heated fuel passes to a collecting cup 49, Fig. 3, in which any fuel vapour condenses, from which cup the fuel passes to a spray carburetter. The heating chambers 26 are formed in the walls of spherical precombust ion chambers 25 which are screwed into the normal sparking plug sockets 22 of an engine which is to be converted from running on petrol to running on heavy oil, the increase in clearance space e being compensated for by a filling piece 83 which is inserted in the combustion chamber and bolted to the end 29 of the precombustion chamber which is provided with orifices 30 to improve the atomization of the combustible mixture, the filling piece 83 having an opening 84 which guides the compressed fuel-air mixture towards the precombustion chamber. The heavy fuel is supplied by a pump through a pipe 38 to a member 34 from which it passes through pipes 33 to the individual heating chambers 26, the heated fuel escaping through pipes 43 connected to a union member 45 and through a pipe 48 to the cup 49 containing a thermometer 51 and a filter 50. The heated heavy fuel from the cup 49 and petrol from a reservoir 59 flow through pipes 54, 57, to separate chambers 56 in a change-over valve device 55, each chamber 56 having a valve 60 controlling the flow of the light or heavy fuel to a common chamber 61 connected to the carburetter float chamber. The valves 60 are opened by levers 65, 65a operated by cables 67, 67a, which are connected to operating knobs on the dashboard of a vehicle. At starting the cable 67a is operated to supply petrol to the carburetter and the engine is operated on petrol until the heavy fuel in the cup 49 reaches a predetermined temperature when the cable 67 is operated to change over to supply heated heavy fuel to the carburetter. A filter 58a for the petrol is fitted on the reservoir 59. The fuel-air mixture from the carburetter is passed through mixing screens 77, 78, Fig. 8, heated by an electric heating element 73, and passed through a spiral bame 81a. The screen 78 is spring loaded and lifts to form a relief valve in the event of blow-back.

Abstract: 1421958 Coating of Al and its alloys SWISS ALUMINIUM Ltd 13 June 1973 [14 June 1972] 28198/73 Heading C7F A continuous Al or Al-based alloy is prepared for soldering by passing it into and out of a molten bath consisting of a molten metal including from 0.005-0.2 wt per cent Ga, and disrupting the surface oxide skin on the continuous material either immediately prior to, or during, immersion in said bath. The coating metal may be Zn, Sn, Pb, Cd or alloys based on one of these; the bath temperature may be 460-480‹C. The oxide film may be disrupted by abrading, brushing or stretching. As shown, Al strip is wound from reel 11 over roller 12 and passes over bars 14 and 15 which are either stationary or move at a different rate to the strip, to disrupt the oxide coating; bars 14 and 15 may be heated to prevent the bath thereto, and one of the bars may be omitted in which case the coating adheres only to one side of the strip. Wiper rolls 21 determine the thickness of the coating, which solidifies on contact with air-cooled roller 18 prior to coiling of the strip at 20.
