Abstract: 1,038,961. Shower baths. G. W. USHER. Feb. 18, 1963 [Nov. 18, 1961], No. 41345/61. Heading A4N. [Also in Division F2] A thermometer 21 is arranged in a transparent pipe 20 to indicate the temperature of the water flowing from a mixer valve to a shower rose. The mixer valve has an outer stationary cylinder 1 with three holes for the supply pipes 3 and outlet pipe 2 and an inner co-axial rotary cylinder 5 with two diametrically opposed elongated ports. An inlet port 6, which can be made partially to overlap with both inlet holes, has a slit extension 8 to provide an attenuated flow of cold water while the hot water is being supplied in full through the main aperture of the port.

Title: Production of active carbon
IPC: C01B31/08
Filed: 1973-09-04
Abstract: 1444732 Active carbon SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 4 Sept 1973 41431/73 Heading C1A Active carbon is produced by cracking a petroleum distillation residue by heating at at least 350‹ C., blowing with an oxygen-containing gas at at least 350‹ C., and then soaking the resulting activable carbon in an oxygen deficient atmosphere at 500‹ to 1200‹ C. The cracking and blowing may be carried out simultaneously. The cracking and/or blowing may be carried out while passing an inert gas, e.g. nitrogen or steam, through the reactor. The oxygen-deficient atmosphere may be steam and/ or carbon dioxide. Prior to soaking, the activable carbon may be extracted, at least partly, with a low-boiling liquid aromatic hydrocarbon solvent, e.g. toluene, granulated, and/or mixed in finely divided form with a binder or reinforcing material, e.g. an argillaceous material such as bentonite, bituminous product, polymeric material, glucose, starch, lignosulphonates, glass powder, and colloidal silica. Prior to granulation, the activable carbon may be mixed with carbon from other sources, e.g. soot obtained upon incomplete combustion of hydrocarbons. The residue may be propanebitumen, or the furfural extract of deasphalted oil.

Apparatus, such as a postal franking machine, locks when a predetermined credit is exhausted and is re-enabled when a card-bearing tray is moved to a position where readings of a serial-number counter, advanced by movement of the tray, and a total-value counter are impressed on the card. In apparatus of the type described in Specification 1,098,366 a lever 36 and claw 35 are aligned with a selected one 30 of a number of gears driven by the value counter, the claw 35 resting between two teeth. Franking of letters proceeds in known manner until the value counter steps the gear 30 to lift the claw 35 and lever 36. A plate 51 moves to the right to open a switch 53 and lock the apparatus. A card 45, for submission to the postal authorities, is placed on a tray 44 which is then pushed into the machine.

Abstract: 1480514 Annealing silicon steels KAWASAKI STEEL CORP 1 Oct 1974 [31 Oct 1973] 42646/74 Heading C7A A process for the production of preferred grain orientated silicon steels with high magnetic inductance for electrical uses, consists in hot-rolling silicon steel alloys containing:- with Fe balance plus impurities. The hot-rolled steel is annealed, cold rolled, intermediate annealed and finally cold rolled to size, the final cold reduction being between 40-80%. After a decarburizing anneal in wet hydrogen at about 820C, the steel is further annealed at 800-920C to produce secondary recrystallization. A final purification anneal at 1200C in dry hydrogen may be given. Significantly improved magnetic inductance may be achieved by the addition of 0À005-0À1% Sb to the alloy. In both cases 0À02-0À2% Mn may be present, as well as small amounts of Al for deoxidation, and the ingots may be vacuum-degassed prior to continuous casting.

Abstract: 1,112,405. Semi-conductor devices. TEXAS INSTRUMENTS Ltd. 2 Nov., 1964 [1 Nov., 1963], No. 43250/63. Heading H1K. [Also in Division G2] Small-area diodes of the Schottky barrier type are produced by coating a metal film 64 with a heavily doped semi-conductor region 62 and a lightly doped region 52 on which is deposited an aluminium oxide layer 54. A photoresist layer is coated on the oxide layer and exposed through a photomask having an opaque strip. The material is then developed and the oxide thus exposed is etched away to form slot 66. The photoresist layer is then removed and a layer of silicon oxide 56 and a photoresist layer are deposited and the material exposed to same photomask turned through 90 degrees. The material is now developed and etched to form slot 68 and well 61 but the aluminium oxide layer 54 underlying slot 68 is not etched as its etching rate is far slower than that of silicon oxide. The remaining photoresist is now removed and a metal film deposited in slot 68 to form terminal 60 and semi-conductor junction 61, the area of the junction being 1.2 x 10<SP>-2</SP> square inches. Alternatively a point contact may be inserted in the well. The masking process may be also applied to integrated circuits. The two insulating layers may both be of silicon oxide.

Abstract: 1,205,244. Ammonium nitrate; explosive compositions. HIRTENBERGER PATRONEN - ZUNDHUTCHEN - UND METALLWARENFABRIK A.G. 22 Sept., 1967 [18 Nov., 1966], No. 43356/67. Headings C1A and C1D. Microcrystalline ammonium nitrate with a lipophilic surface is produced by crystallization from concentrated or saturated aqueous solutions of NH 4 NO 3  in the simultaneous presence of salts of primary amino-alkanes in an amount of 0À1 to 5% by weight of NH 4 NO 3 , their chain lengths ranging from C 8  to C 18 , and salts of short chain amino alkanols containing 2 to 4 carbon atoms per hydrocarbon chain in an amount of 0.2 to 5% by weight of NH 4 NO 3 , at a temperature between 20 and 90 C. Crystallization may be effected by cooling, evaporation at atmospheric or reduced pressure, or by spray drying. Suitable salts are those derived from acetic, formic, lactic or nitric acid such as ndodecylamine acetate, tetradecylamine lactate, triethanolamine acetate, 2-amino-2-methyl-1- propanol - lactate, 2 - dimethyl amino - ethanol acetate. The ammonium nitrate crystal surface has the physical characteristic of a hydrocarbon chain and is capable of adsorbing organic liquids. It is also hydrophilic. The ammonium nitrate can be used in making explosives or blasting agents and those with Fuel Oil No. 4 retain their normal explosion characteristics and sensitivity towards detonators No. 6 or No. 8 even after storing for six months.

Title: A method and apparatus for extracting heat in the treatment of aluminium
Inventor: GROVES JAMES DENIS
IPC: C22B21/06
Filed: 1962-11-21
Abstract: In an apparatus for the production of aluminium trichloride by the chlorination of molten aluminium, heat is withdrawn from molten aluminium by a solid aluminium plug, one end of which extends through the container wall so as to be in contact with the molten metal, and the other end of the plug being cooled by a flowing liquid or by an air blast.  As shown, the casing has a lining 2 of refractory ceramic or concrete.  Pipes 8 and 9 inject chlorine into the vessel below and above the molten metal level therein.  The reaction products are discharged at 13.  The temperature inside the vessel is maintained at the desired value during the reaction by controlling the cooling effect of the finned plug 10.  When the supply of chlorine is cut off to stop the reaction, an inert gas such as nitrogen or argon may be passed through the aluminium as it solidifies hence forming a honeycombed mass to aid contact by the chlorine when the process is restarted. Alternatively and as shown, the container may have an additional solid aluminium plug 12 which is <PICT:0992669/C1/1> cooled during the reaction by an air blast. When the reaction is to be stopped the fluid cooling of the plug 12 is also cut-off so that the plug immediately melts and allows the still molten aluminium to be drained off before it can solidify.  In one of two examples described an initial charge of 70 lb. of aluminium is heated by the gas poker to about 450 DEG  C.  Chlorine is introduced at about 2 cu./ft./min. through pipes 8 and at about 0.3 cu./ft./min. through pipe(s) 9. The cooling of plug 10 is regulated to maintain the temperature in the vessel 1 at about 900 DEG  C. In the other example, the initial aluminium charge of about 401 lb. is preheated in a separate vessel to about 300 DEG  C. before being put into the vessel 1.  Chlorine is admitted as in Example 1 and further charges of aluminium are added at intervals of 15 mins. before a final reduction to 6 lb. per hour.  The temperature in the vessel 1 is maintained within the range 750 DEG  to 800 DEG  C.
