Title: Improved process for obtaining tanning materials from cellulose waste sulphite lyes
IPC: C14C3/24
Filed: 1920-07-07
Abstract: Waste sulphite-cellulose lye is treated with lime or calcium carbonate to neutralize the acids, and is separated from the precipitate.  The calcium is then precipitated by alkali compounds such as sodium carbonate or silicate.  Hydrochloric, sulphuric, or other acid is added to the resulting solution of sulpho-lignates in amount equivalent to 50-100 per cent of the alkali used in precipitation.  The liquid can then be used for tanning.  Instead of acid, there may be added salts of metals such as are used in mineral tanning, for instance aluminium, iron, or chromium chloride; the liquids thus obtained can be used directly p  for tanning.  The liquid may be fermented after the addition of the lime or calcium carbonate, and may be concentrated by evaporation after the treatment with the alkali compound.ALSO:Waste sulphite-cellulose lye is treated with lime or calcium carbonate, to neutralize the acids, and is separated from the precipitate.

Title: Metallic pipes lined with glass
IPC: F16L58/14
Filed: 1960-05-31
Abstract: 901,126. Lining metal pipes. TANAKA, S. May 31, 1960 [June 18, 1959], No. 19193/60. Class 99(2). A metallic pipe 1 lined with a glass pipe 3 has an inorganic, heat resisting buffer layer 2 having a fusion point below that of the pipes 1, 3 interposed between them, the pipes and buffer layer being heated together to the softening temperature of the glass pipe, and immediately expanded by blowing high pressure gas to fill the softened glass pipe which simultaneously renders the pipes 1, 3 and the buffer layer 2 into one body under pressure, a relatively low compressive stress being imparted to the glass pipe by the metal pipe during the cooling thereof. As shown, the glass pipe 3 is inserted in the metal pipe 1 after the inner surface of the pipe has been roughened by emery blasting and coated with a slurry of the buffer layer material and water. One end of the pipe 3 is closed by fusion, and the other is provided with a flange 5 which is hermetically sealed by a rubber board 7 interposed between clamping boards 6 and 8. The assembly is heated, e.g. by an induction furnace 10 to the softening point of the pipe 3 when gas under pressure is passed through a feed pipe 9, which forces the glass pipe to adhere via the buffer layer 2 to the pipe 1. The excess glass portions are cut off after the metal pipe has cooled. The buffer layer comprises sodium oxide, lead oxide, silicon dioxide and boron oxide, which may be mixed with a metal salt that on heating generates gas. In this latter case a number of fine bubbles are present in the buffer layer.

Title: Improvements in the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1960-05-31
Abstract: In the production of hydrogen peroxide by the anthraquinone process, there is present in the working solution ammonia or an ammonium salt, preferably in an amount of 10-6 to 10-1 mols per litre and such that the pH of the extracted hydrogen peroxide remains below 8, the presence of which enhances the activity of the hydrogenation catalyst employed.  Anthraquinones referred to are mono and polysubstituted anthraquinones with alkyl, halogen, alkoxy, or mixtures thereof, as substituents.  In examples, 2-ethyl antraquinone is employed. Solvents for the anthraquinone include aliphatic, cycloaliphatic and aromatic alcohols and their esters, phosphoric acid esters, ketones, hydrocarbons with 6 to 20 carbon atoms, and the above with halogen substituents, or mixtures.  In examples a mixture of 1-methyl naphthalene and octyl alcohol is employed.  The catalyst may be employed as a fixed, fluidized, or suspended bed, or in the form of a mesh or sieve.  Examples refer to the use of platinum black and palladium on alumina.  The Specification includes a detailed discussion of prior art.  Specification 795,272 is referred to.

Filed: 1922-07-10
Abstract: 205,452. Charbonnier, P. J. July 10, 1922. Ordnance breech mechanism.-Relates to guns having a part-spherical or like breech-block 3 with a central orifice for loading, as described for example in Specification 201,394, the cartridge case x being partly extracted during the opening rotation of the block by a device as described for example in Specification 205,177. According to the present invention, the cartridge case, is ejected by a member 36 which during the opening rotation of the block engages the rim of the case by means of a hook 59 and also, by means of a hook 58, engages a catch 46 to release a plate 37 urged rearwards by an ejecting spring 38. This spring, which is cocked against a fixed spring-stop 49 during run-out, acts through the plate 37 to slide the member 36 rearwardly in the clock and pull the case through the loading opening. The rearward movement of the plate 37 compresses a second spring 39 which reacts to return the parts after a projection 50 has depressed the spring stop 49. In a modification, toothed gearing is provided to make the rearward movement of the plate 37 greater than the length of recoil of the gun.

[Also in Divisions A1, A2 and F1] A unit for storing live shellfish such as lobsters, crawfish and mussels, comprises a plurality of trays disposed one above the other, each tray having at least one perforation, the uppermost tray being provided with a sea-water feeding means, the unit also having temperature controlling means, and means for aerating the water to simulate natural environmental conditions. The unit comprises a cabinet, Fig. 1, having two portions divided by insulated wall 26 (of expanded polystyrene) and having plywood side walls 22 and base 23. Trays 25, Fig. 2, having perforations 33 and overflow 32, are stacked in one portion, whilst the other portion houses a refrigerating system 35 having an aluminium or stainless steel evaporating system 36 disposed in sea water reservoir 29, and a water pump 28 which pumps sea water from reservoir 29 to outlet 31 below the level of the water above shelf 24. The sea-water then proceeds under gravity through perforations 24a through the trays 25, the level in each tray being determined by the dimensions of the perforations 33 and overflow 32. Also disposed beneath shelf 34 are thermostatic control 38 and heating element 39. Transparent lid 43 covers the cabinet and levelling screws 44 are fitted on the base. The pump, preferably fabricated from synthetic resinous material, which allows a high degree of aeration to the sea-water comprises a rigid casing 53, Fig. 5, having a knuckle 54 on the internal surface against which flexible vanes 55 of impeller 56 impinge when rotating. Air enters through inlet 57 and water through inlet 58, both entries being on the suction side of the pump. The water saturated with air is expelled through outlet 59. Aeration may also take place by cutting out the pump (by a controlled time clock) and allowing the water to drain out of the trays which causes displacement of air. Other embodiments of the storage unit are described comprising walled units having disposed externally of the walls either an air refrigeration unit or an immersion refrigeration unit. A larger unit constructed of timber and aluminium has an air cooling system as well as the water cooler. In conditions too cold for live shellfish storage the sea water in the reservoir may be heated by a heating element and a thermostat may be dipped in the reservoir. If natural sea-water is not available, artificial sea water may be made by adding suitable salts to distilled water (example given). A display cabinet may be connected to the storage unit by polythene tubing.

Filed: 1949-07-25
Abstract: 674,973. Fusible cut-outs. DRIESCHER, F. July 25, 1949 [June 10, 1949], No. 19538/49. Class 38 (i). In a fuse having elements 4, 7 connected in series, the element 4 is disposed in a cartridge 3 containing arc-quenching material 5 and the element 7 is connected by a soldered joint 8, outside the cartridge, in series with a disconnecting spring 9. Thus the heat accumulated due to a prolonged overload causes the solder to melt, whereupon spring 9 quickly breaks the circuit. Arcing at the soldered joint is prevented by providing a further fuse element 10 in parallel with element 4 inside the cartridge. As shown, the parts 7, 8, 9 are duplicated on the other side of the cartridge to make the cutout effective against thermal overloads occurring on both sides of the fuse, but said parts may be provided at one side only of the cartridge. The Specification as open to inspection under Sect. 91 describes also a fuse in which a pair of springs, one at each end of the cartridge, are connected together by a soldered joint outside the cartridge and in parallel with the element 4. This subject-matter does not appear in the Specification as accepted.
