Title: Improvements in or relating to grinding wheel truing mechanism
IPC: B24B53/08
Filed: 1941-03-05
Abstract: 548,351. Trueing grinding-wheels. JONES & LAMSON MACHINE CO. March 5, 1941, No. 3024. Convention date, April 4, 1940. [Class 60] A tool for trueing a grinding wheel 36 to a formed contour such as 54, Fig. 2, is controlled by a pattern 45 of larger size and the dimension thereof may be enlarged to a greater degree in one direction than at right angles thereto. The too] may comprise one or more diamonds 27, Fig. 1, and be adjustably mounted on a bar 8 which is pivoted in a frame 9 and secured to a sleeve 61 which is urged to the right by a spring 80. The frame 9 is carried by pivots 12 and is oscillated by a block 133 on a screw 132 which is driven by a motor through automatically reversed gearing 120. The frame 9 carries a shaft 15 which is moved axially, as the frame oscillates, by the pattern 45 and follower 41 and, acting through a lever 60 fulcrumed at 65 to the frame and at 60a to the sleeve 61, moves this and the tool 27 through half the distance the shaft 15 moves. The tool at the same time is moved laterally through one quarter the distance moved through laterally by the follower 41. To prevent errors due to the tool and follower oscillating about the pivots 12, the sleeve 61 has an arm 90, Fig. 4, anchored by a link 93 and teeth 97 engaging a long pinion 98 which is engaged by teeth 78 on a sleeve 77 secured to the shaft 15. Dust is excluded from the casing 1 by a flexible cover 35. The casing 1 is intended to be connected to and used with the grinding machine described in U.S.A. Specification 2,184,011.

Title: Process of manufacturing simultaneously pure aluminium oxide and magnesium-ammonium phosphate
IPC: C01F7/34
Filed: 1938-02-01
Abstract: 515,664. Magnesium ammonium phosphate; aluminium oxide. ASSEEV, C. D'. Feb. 1, 1938, No. 3114. Void. Convention date, Feb. 1, 1937. [Class 1 (iii.)] Aluminium sulphate obtained by treating aluminous minerals with sulphuric acid is treated with magnesium-bicarbonate solution to precipitate basic aluminium carbonate which is then converted into alumina. The remaining magnesium sulphate solution is used with an addition of sulphuric acid to treat calcium phosphate, yielding calcium sulphate and magnesium hydrogen phosphate. The latter is treated with magnesium and ammonium bicarbonates to produce magnesium ammonium phosphate. Similarly, the aluminium sulphate may be precipitated with ammonium hydroxide and the ammonium sulphate used to treat the calcium phosphate. The ammonium hydrogen phosphate is then treated with magnesium bicarbonate with or without addition of ammonia or ammonium bicarbonate. Specification 401,407 is referred to.

Title: Improvements in or relating to vapour vacuum pumps
IPC: F04F9/00
Filed: 1950-02-08
Abstract: 721,667. Condensation pumps. EDWARDS & CO., (LONDON), Ltd., W., LATHAM, D., and POWER, B. D. July 16, 1951.. [Feb. 8, 1950] No. 3276/50. Class 71. A vapour vacuum pump in which vapour ejected from one or more jets 4, 5, 8 supplied directly from the boiler of the pump is condensed on a surface 2, a portion of the surface is heated to effect vapourization from the thin liquid film flowing down said surface, of the more volatile fractions of the film, which vapour is used to feed one or more additional jets 8 of the pump. The vapour condensed on the surface of the pump casing 2, which may be air or water cooled, passes through the narrow annulus A-B between the casing and the skirt tube 7. The region B-C of the casing is heated by conduction from the boiler, supplemented if necessary by an external heater, and it may also be provided with radiation shield to conserve the heat. When the condensed liquid reaches B the more volatile constituents are evaporated and are fed through an annular duct 11 to the jet 8 which discharges into a mixing tube 9 leading to a pipe 10 connected to a rotary backing pump. The volatile vapours may condense in a trough 14 and be drawn off through a tap 15. The jet 8 will tend to entrain and remove from the space 13 any high vapour pressure fractions which remain therein and will also produce in the space 13 a sufficiently low partial pressure of air for degassing the fluid film on its way to the annulus A-B. In other embodiments the vapour produced from the heated surface is used to feed both jets 4, 8, or the jet 8 may be omitted and one or more annular jets, such as 4 are then supplied with the vapour.

Abstract: 1,105,180. Packaging-machines; closing hinged lids. KLIKLOK CORPORATION. 24 Jan., 1967 [10 Feb., 1966], No. 3438/67. Headings B8C and B8P. The hinged lid 17 of a box and some (19, 20, 21) of its flaps are folded (and the flap 20 glued ) while the box is conveyed in the direction of its hinge line 16. The box is then advanced at right angles to the hinge line whilst the remaining flaps 22, 18 are folded (and the flap 18 glued), and whilst the bottom 38 of flap 19 is raised, glued and refolded. A continuous tear strip 23, 24, 25 which is not adhered to the box wall is formed around the lid flange. In the embodiment, the lid 17 is folded by a plough 29. After rotary members 30, 31 have folded flaps 19 and 21 respectively spots of glue are applied beneath the outer portion of flap 20 outside the tear strip zone by spokes 33. Double ended spokes 34 apply adhesive to the flap 20 on either side of the tear strip in the zone in which the flap overlies flap 21. After the flap 20 has been folded by a plough 36, the box is advanced at right angles to the hinge line either by transference of the box on to a conveyer at right angles to the first or through a 90-degree turn of the box caused through chain conveyers running at different speeds. Spots of adhesive are applied to the lower part 38 of the flap 19, to the lower part of flap 18, and also to the flap 18 above the tear strip in the region where the flap overlies flap 22. The flaps 18 and 19 are folded by ploughs 42 and 41. The glued portions may be held in compression for a time afterwards.

Title: Plug valve
IPC: F16K5/22
Filed: 1977-02-01
Abstract: The cone (plug) valve (10') has a cone-shaped closing element (22') which is rotatably mounted in a corresponding housing (24'). It is provided with circumferential grooves (84') near to its upper and lower ends, these grooves being connected to one another by longitudinally extending grooves (82'). The upper circumferential groove is connected via a bore (85) to a non-return valve (83) through which a pressurised lubricant can be introduced. This lubricant penetrates into the grooves (82', 84') and, by virtue of its pressurising and lubricating effect, prevents the closing element (22') from becoming jammed in the housing (24') when upward-acting axial forces occur. <IMAGE>

Title: Improvements in the process of preparing aromatic arsinic acids
IPC: C07F9/74
Filed: 1919-02-20
Abstract: Aromatic arsinic acids are obtained by the reaction of aromatic diazo compounds upon acid, neutral, or alkaline aqueous or dilute alcoholic solutions of arsenious acid, in the presence of a copper salt and a reducing-agent appropriate to the medium used.  Suitable reducing-agents are: for acid solutions, hypophosphorous acid or a mixture of sodium hypophosphite and hydrochloric acid, or cuprous hydrate; for neutral solutions, sodium hydrosulphite or sodium formaldehyde sulphoxylate; for alkaline solutions, sodium hydrosulphite, formaldehyde hydrosulphite, or formaldehyde sulphoxylate, or the sodium arsenite itself used in excess.  The process may be carried out in the cold or at a moderate temperature; when working in acid solution, the diazo compound may be replaced by the aromatic amine in conjunction with sodium nitrite.  Examples are given of the preparation of phenylarsinic acid in acid, neutral, and alkaline solutions, using copper sulphate as the copper salt, sodium arsenite Na2HAsO3 or a solution of arsenious acid in caustic soda or sodium carbonate solution as the source of arsenic, and sodium hypophosphite, sodium hydrosulphite, or the excess of sodium arsenite as the reducing-agent in the acid, neutral, or alkaline solutions respectively.  The following products are specified also: - p-methylphenylarsinic acid, p-chlorphenylarsinic acid, p-chlor-m-nitrophenylarsinic acid, p-bromphenylarsinic acid, p-brom-m-nitrophenylarsinic acid, p-methoxyphenylarsinic acid, p-methoxy-m-nitrophenylarsinic acid, p-ethoxyphenylarsinic acid, p-ethoxy-m-nitrophenylarsinic acid, phenylsulphonyl-p-aminophenylarsinic acid, p-oxyphenylarsinic acid, p-oxy-m-nitrophenylarsinic acid, and p-oxy-m-urethanophenylarsinic acid.  Specification 568/11 is referred to. p ALSO:Sodium arsenite of the formula Na2HAsO3 is obtained by fusing arsenious oxide with two molecular parts of sodium carbonate in absence of air, dissolving the product in water, evaporating to a syrupy consistency, and allowing to stand for some time at 30-40 DEG  C.
