Title: Improvements in vacuum apparatus for the transfer of liquids from one vessel to another
IPC: B67D7/72
Filed: 1948-03-25
Abstract: 645,297. Vacuum apparatus for raising liquids. GRAYSON, Sir H. M., and HARROLD, G. March 25, 1948, No. 8787. [Class. 102(ii)] In apparatus for transferring liquid from one vessel to another, e.g., removing sludge from an oil bunker to a barge, an intermediate tank 1 is connected by pipe 2 to the nozzle for sucking up the liquid and by a pipe 4, situated above the maximum level to which the liquid may normally rise in the tank 1, to a vacuum pump 6. A separator vessel 5 interposed between the pipe 4 and pipe 7 to prevent oil being drawn into the vacuum pump and the vessel 5 has a depending standpipe which is liquid sealed at its lower end 9 and is of a length in excess of the barometric head or at least in excess of the suction head of the vacuum pump. The liquid in the tank 1 may be transferred by opening valve 3 and an atmospheric 'valve 11. Valves 12, 13 connected to sources of air and.steam.press,ure may be fitted to force the liquid from the tank 1. Two intermediate vessels 5 may be used in parallel.

Title: Improvements in or relating to dies for pressing or moulding
IPC: B29C33/56
Filed: 1946-03-21
Abstract: A metal-faced laminated material for use as a die for moulding resinous compositions or laminates is made by interposing a metal foil between a pattern-producing sheet or surface and a stack of paper or fabric sheets impregnated with a thermo-setting resin, hot-pressing to cure the resin, and removing the cured die from the pattern-producing sheet or surface.  The pattern-producing sheet may be a fabric, e.g. an open-weave fabric, lace, wire mesh, or an embossed or engraved plate; it may be composite, consisting, e.g., of a metal foil over an open weave fabric, or of a patterned top sheet to produce a design super-imposed on a background pattern.  Adhesion of the metal foil to the stack may be ensured by coating it with an adhesive such as a blend of a polyvinyl acetal resin such as the butyral with a thermosetting phenol-aldehyde resin.  Aluminium foils may be anodised and coated with a hardenable resin as described in Specification 587,536, [Group VIII].  The die may be surfaced with two aluminium foils, the inner one being anodised and resin-treated on both sides; the outer one, which is not anodised or resin-treated, may be brush-finished.  The die may be prepared with a relief surface on both sides, of the same or different designs.  Specifications 145,123, [Class 140], and 414,632 also are referred to.

Abstract: 938,525. Cleaning root vegetables. ELFAAPPARATE-VERTRIEBS-G.m.b.H. March 8, 1962 [March 21, 1961], No. 8879/62. Class 117. Apparatus for separating residual fragments of root crops from a conglomeration with weeds, leaves and the like comprises washing means 1 for removing stones and heavy impurities with means 1c for disentangling the conglomeration and means 3 and 4 for separating the residual fragments from the remainder of the conglomer tion. The working tank 1 is fed from a worm 2. At 1a stones and other dense impurities sink to the bottom of the tank whilst the remainder floats over a weir on to closely packed tooth disc wheels 1c which counter rotate to disentangle leaves, weeds and the like and drip them down a drain shaft 1b. The remainder of the conglomeration, still wet, then falls in succession on to the upwardly moving surfaces of the inclined conveyer belts 3 and 4 upon which the leaves and weeds are carried upwards whilst the fragments of the roots roll back down the slope and are collected,-the separation being due to the varying adhesive properties of the different components on the belt.

Abstract: 164,193. Anderson, W. J. March 29, 1920. Resistance ovens.-An incubator is heated by a special electric heater supplied with current from a main circuit provided with a circuit breaking device automatically operated by means of an auxiliary circuit which is opened and closed by a thermostat comprising an air-tight hollow capsule. The incubator has a skeleton frame consisting of corner posts 7, Fig. 2, and connecting battens 8. Double walls are formed by sliding sheets 10 of asbestos composition &c. A removable cover 13, doors 14, and transparent panels 15 are provided. A double air-tight capsule 24 is adjustably connected with a control lever 19 by means of a rod 25 and screw 26. The lever 19 carries an adjustable balance weight 20 and a plug 21 to make contact with a mercury cup 22. Above the egg-tray supports 16 is the electric heater 28 shown in plan in Fig. 4. It consists of two connected units 29 each made up of wires 33 of nichrome, etc. wound in zig-zag form on grooved tubes 32 of fibre, porcelain, mica, or other insulating material. The tubes 32 are carried by metal cores 30 riveted to end bars 31. The wires 33 are connected with the main circuit 34 through leads 41, 42, 43 and a relay or circuitbreaker 38. The auxiliary circuit 35 extends from a battery 37 through the control lever 19 and mercury cup 22 to the electromagnetic circuitbreaker 38 and thence back to the battery 37. An inspection light 39 and control switch 40 are provided in a shunt circuit 36. Current normally flows through both circuits 34, 35 until contact between the plug 21 and mercury cup 22 is broken by the raising of the lever 19 by the capsule 24. The circuit 35 being thus broken the no-volt coil in the circuit breaker 38 is de-energized and the main circuit broken. When the incubator has cooled sufficiently, the plug 21 again makes contact with the mercury cup 22 and the circuits 34, 35 are re-closed.
