Abstract: 686,404. Valve closure members. GODFREY, H. R. June 29, 1951 [March 29, 1950], No. 7822/50. Class 135. In a washer or jumper assembly for water and like taps comprising a resilient disc element 14 fitted within a substantially rigid holder 13, having a continuous flange 13<SP>1</SP> or a number of spaced tongues or projections, the seating face 18 of the element 14 projects in front of the peripheral edge or edges 15 of the flange or projections and a space 16 is left between the periphery of the element 14 and the side wall of the holder 13 so that when pressure is applied to the back of the holder in the normal operation of the tap, the element 14 on engaging the seat 4 of the tap is deformed and a part enters the space 16. Thereafter the edge 15 of the holder engages the seat 4 so that further compression of the disc element is positively prevented and the material of the element is not trapped between the edge 15 and the seat 4. The disc element 14 may be of natural or synthetic rubber and is preferably of frustro-conical shape. The central portion of the disc 14 within the seat 4 may be recessed. As shown the holder has a continuous flange 13<SP>1</SP>. The washer unit shown is formed as a separate unit from the jumper but it may be formed as a part of the latter. Thus the disc portion 10 of the jumper may be made cup-shaped to receive the resilient disc element 14. The element 14 may be held in the holder 13 by an adhesive or by the nut 12 on the spigot 11 or it may be a force fit in the holder.
Patent GB-472229-A (GB)
Title: Process for manufacturing pure compounds of aluminium
IPC: C01F7/748
Filed: 1936-03-16
Abstract: In a process for obtaining pure aluminium compounds wherein metallic iron is dissolved in crude aluminium sulphate solutions containing iron as an impurity, and an SO4-containing compound of aluminium or of aluminium and iron is precipitated from the reaction liquor, the crude solution is used in concentration above 45 per cent (AL2SO4)3.18H2O.  The aluminium sulphate solution is obtained for example by dissolving bauxite, alumina, waste aluminium, &c., in sulphuric acid.  Before treatment with metallic iron, iron present is reduced to the ferrous state.  The metallic iron, comprising waste iron, filings, powder, &c., should be activated or cleaned from grease, either mechanically or by etching with sulphuric or hydrochloric acid, and small amounts of the cleansed iron should be successively added to the solution until no more is dissolved, as indicated by the cessation of the evolution of hydrogen.  The process may be carried out in a countercurrent manner.  Dissolution is effected first at 70--90 DEG  C, then at the boiling point of the solution.  When complete dissolution has been effected, metallic iron is removed from the solution by filtration or centrifuging, and may be re-employed after "reactivation."  The solution is then cooled, whereupon a presumably complex salt containing aluminium, iron and sulphate radical separates.  This is taken up with hot or boiling water and further diluted whereby pure basic aluminium sulphate containing but little SO4-ion precipitates.  Alternatively, the solution freed from metallic iron may be immediately diluted to precipitate the basic sulphate.  Oxidizing conditions should be excluded from the process after dissolution of the iron, the diluting water being previously boiled to remove air.  Hydrogen or nitrogen may be passed through the solution during the precipitation step. Further basic aluminium sulphate separating from the solution on long standing or otherwise during the process is incorporated with the starting solution of a fresh reaction. Pure ferrous sulphate may be obtained by concentrating the solution obtained after separation of the basic aluminium sulphate, and may be converted to ferric oxide.

Filed: 1944-04-27
Abstract: 576,207. Miniature engines. SPAREY, L. H. April 27, 1944, No. 7880. [Classes 7 (ii), 7 (iii) and 7 (v)] A miniature engine, particularly suitable as a two-stroke engine for use in model aeroplanes and boats, has one or more cylinders and fuel tanks radiating from the crank-case. As shown, the single cylinder engine has a fuel tank 33 diametrically opposed to the cylinder 21 so as to assimilate an opposed cylinder engine, the tank being made the same size as the cylinder and having fins 35. The invention is also applicable to radial-cylinder engines. The carburetter comprises a telescopic air inlet passage 39 which extends outside the model so as to be capable of being closed by a finger to facilitate starting and a nozzle at the end of a pipe 40 through which fuel is drawn by engine suction, the delivery being controlled by a needle valve on the end of a long shaft 43 which can be adjusted by a knob 46 outside the model. The crank-case is open on one side to allow the crank-shaft, which has a bearing only on the other side, to be assembled. After assembly, the crank-case is closed by a disc plate projecting into the crank chamber. The supply of mixture to the crank-case is controlled by a disc valve 15, or a sleeve valve, and the mixture after compression by the piston is conveyed to the combustion chamber by a transfer passage 23 and port 25, a piston baffle 30 being provided. An ignition cut-out lever which extends outside the model is attached to the normally stationary contact of a make and break device but has enough flexibility to be capable of flexing to prevent the contact points from opening. A twin cylinder engine is also described, the cylinders being arranged at less than 180‹ to one another, preferably at 90‹ and the fuel tank extending from the bottom of the crank-case. Both cylinders fire together, the crank case serving as a common induction chamber. This arrangement may be modified by dividing the crank case into separate chambers, each chamber having a separate disc valve and the cylinders being fired separately. The cylinders may have detachable heads and be formed integrally with both the fuel tank and the crank-case.
