Title: Rotary card filing device
IPC: B42F17/28
Filed: 1951-09-25
Abstract: 714,079. Filing papers. NEUSTADTER, A. Sept. 25, 1951 [March 30, 1951], No. 22409/51. Class 146(1) A rotary filing device comprises a shaft supported near its ends in a casing, a pair of separate rail wheels carried by the shaft, the rails of which engage slots in a stack of dual-slotted record cards, the wheels being slidable axially relatively to the shaft and constrained to turn therewith, the shaft being manually rotatable for consultation of the stack of cards. The casing 10 comprises a low front wall 12, a rear wall 13 with curved top part 14 and side walls 15 having wings 16 in which seat bearings 29 for a shaft 28. The arcuate shaped lid 17 is rotatably mounted thereon by rings 20 on its side panels 19 and has a lip 21, covered by a strip 24, to limit movement, a latch 25 being provided which may be locked, as at 27. The shaft 28 has a cut-away part 31, or is otherwise non-circular, and rail wheels 35 having a similar shaped hole by which they are mounted on the shaft. Spacing members 39, 45, between the rails and the rails and casing, may be rotatably mounted but will normally be carried round with the shaft 28. The assembly is carried out by passing the shaft through the successive parts, and secured by operating knobs 33 fixed to the projecting ends 32 as by set screws 34. The width of the spacing members is such as to allow a smaller amount of axial movement to the positions shown at 145 but so that the overall width is slightly greater than that of the cards 41 which have T-hole slots 43 to fit over the rails 35. Each rail 35 comprises stamped plates 37 shaped circumferentially to provide opposed U-shaped flanges 38. In a modification, Fig. 6 not shown, two sets of cards, rails and spacing members are accommodated on separate shafts each of which has its inner end rotatably mounted in a sleeve secured to the inner spacing members, so that operation of a knob 33 turns only one set of cards. In a further suggested modification, one or more sets of cards, rails and spacing members are accommodated on separate shafts between the outer two sets of cards, each pair of shafts being coupled together in a sleeve, the inner set or sets of cards being rotated either directly by hand. or by means of an enlarged wheel mounted on the shaft. Index cards 42 with projecting tabs have T-hole slots 443 to fit over rails 35.

Title: Improvements in and relating to the deposition of metal
IPC: B05B7/16
Filed: 1951-09-26
Abstract: 735,695. Coating with metals. BRENNAN, R. M. Sept. 26, 1951, No. 22500/51. Class 82 (2). [Also in Group XXIX] Molten metal supplied from a constant head to a spraying nozzle 26 has its temperature controlled during its passage therethrough and the sprayed metal, e.g. aluminium, is deposited on a continuously moving band 61, e.g. of paper, metal, glass, &c. carried on rolls 63. The metal is melted within a container 12 by a high frequency induction coil 31 and passes through a gate valve 19 to a duct 17 where the molten liquid level is maintained constant by means of a float 22 controlling the gate valve. An overflow lip 69 delivers surplus metal to a tank 74 from which it is fed by a pump 65 back to the container. A float 32 shuts off the supply to the nozzle when the metal level falls. A high frequency induction coil 27 surrounds the nozzle which is supplied with spraying gas from a pipe 28. The nozzle may be of elongated form with a surrounding spraying gas passage, or may comprise a number of laterally-spaced outlets with a gas outlet surrounding them. A conical guard prevents the entrance of air into the spray and is surrounded by an induction coil 163 which controls the spray temperature. The spraying gas temperature is controlled by a thermostat, and the apparatus may be enclosed within a pressure chamber so that the pressure on the metallic surface in the duct 17 can be varied. Metal is fed to a ladle 60 and is transferred to the container by turning a crank 62.

Title: Improvements in the manufacture of oxygenated organic compounds
IPC: B01J27/18
Filed: 1929-07-24
Abstract: 338,854. Dreyfus, H. July 24, 1929. Oxygenated organic compounds such as ethanol, propyl alcohol, acetaldehyde, acetic acid, methyl acetate and their higher homologes, and ketones. are obtained from mixtures of hydrogen and oxides of carbon such as water gas, coke oven gas or producer gas in the presence of catalysts consisting of alkali or alkaline earth or copper silicates, borates or phosphates or salts of other oxyacids of phosphorus. The products vary according as the catalysts contain an excess of basic or acidic radicle over the normal content. In place of the above reactants, compounds obtainable by synthesis therefrom, such as methanol or ethanol, may be employed under pressure. They may be prepared prior to the main reaction by passing the gases over zinc oxide or basic zinc chromate. Compounds capable of yielding methanol such as methyl formate or acetate or dimethyl ether may alternatively be employed. Temperatures of 200-600‹ C., and especially 250-400‹ C., and pressures of 50-500 atmospheres or more are preferably used. Methane or inert gases such as nitrogen may be present. Reaction chambers of copper or steel lined therewith, or of steel containing molybdenum, tungsten, manganese, cobalt, or nickel are conveniently employed.

Title: Process for the production of elastic plastics of high molecular weight
IPC: C08G18/26
Filed: 1957-07-18
Abstract: In a process for the production of elastomeric polyurethanes of high molecular weight by reacting a preliminary addition product prepared from a polyhydroxy compound having a molecular weight of at least 1,000, a polyisocyanate and a glycol with a further quantity of a polyisocyanate, the preliminary addition product is reacted at a temperature greater than 50 DEG C. with the polyisocyanate in the presence of a compound which splits off free amines at temperatures higher than 50 DEG C.  Such compounds are, for example, heavy metal salt (such as copper chloride) complexes of collidine, acridine, pyridine or quinaldine, salts of substituted dithiocarbamic acid, such as the zinc salt of ethyl phenyl, dimethyl or dieithyl thiocarbamic acids, or condensation products of aldehydes with amines or ammonia, such as hexamethylene tetramine.  Basic oxides such as lead oxide or zinc oxide intensify the action of the substance splitting off the amine and acidic oxides such as titanium dioxide, iron oxide or antimony oxide reduce it.  Polyesters, polyester amides, polyethers or thioethers and polyocetals are suitable polyhydroxy compounds.  In examples a reaction product of an adipic acid ethylene glycol polyester or a polythioether from thiodiglycol is used is the polyhydroxy compound and 1,4-butylene glycol as the glycol.  As compounds splitting off amines there are used variously zinc ethyl phenyl dithiocarbamate, alone or with zinc oxide, or iron oxide, or the copper chloride complexes of puridine, quinoline or collidine.

Abstract: 633,413. Respiratory appliances. BENDIX AVIATION CORPORATION. July 31, 1946, No. 22877. Convention date, Sept. 24, 1945. [Class 81 (ii)] [Also in Group XXIX] An air regulator for automatically supplying the necessary air to a diver equipped with only a rubber face mask, comprises a cylindrical casing 11, Figs. 2, 3, having a compressed-air inlet 19, an outlet 16 connected to the mask, and a flexible diaphragm 44 subjected on its outside to the ambient water pressure and on its inside to the pressure in the-casing chamber 45. Within the inlet 19 is a filter 21 and a spring-loaded inlet valve 32, the stem 28 of which coacts with an adjustable screw 42 carried on a lever 40 pivoted on the casing at 41 and provided with a rod 43 which contacts the diaphragm. Arranged diametrically opposite the outlet 16 and on the outlet side of the valve 32 is a jet pipe 60, whilst located at the lowest point on the flat face of the casing 11 is an exhaust valve 58 held closed by the ambient water pressure and a leaf-spring 56. A byepass valve 34 operable by a handle 37 is provided to permit flow of air to the diver on the failure of the regulator. In operation, inhalation by the diver reduces the pressure in the chamber 45 resulting in the inward movement of the diaphragm and the opening of the valve 32. The flow of air through the jet pipe 60 creates a suction to further reduce the pressure in the chamber 45 and hence assist the diver to maintain his air supply. This suction varies with the rate of flow of air supplied to the regulator, which rate may be increased when the diver has to work at greater depth or exert more effort, so that the valve 32 may be maintained open solely by the jet pipe suction. Exhalation by the diver opens the exhaust valve 58 to expel stale air and any water that may have collected in the casing.

Abstract: 533,513. Vitamins. JACKSON, L. MELLERSH.- (St. Louis University, President & Board of Trustees of). Aug. 10, 1939, No. 23129. [Class 2 (iii)] The anti-haemorrhagic vitamin K is concentrated by adsorption in a base-exchange silicate and description by a solvent and further concentration may be effected by repeating the process with the same or a different adsorbent such as carbon or by high vacuum distillation or crystallization. Vitamin K is said to comprise two distinct chemically related bodies, K, obtained by strongly chilling an acetone or alcohol solution of the vitamin from alfalfa, and K 2 obtained from putrified fish meal. The base exchange silicate known as Decalso (Na 2 O : Al 2 O 3  : SiO 2  = 1 : 1 : 6) is preferred for the first concentration and the silicate sold under the Registered Trade Mark "Permutit" is preferred for further fractionation and for isolating vitamin K  2 . In examples (1) Alfalfa is extracted with petroleum ether and the extract is passed through a column of Decalso, the column then being washed with four portions of petroleum ether, the third and fourth washings which contain most of the vitamin being then further fractionated with Decalso or "Permutit"; still further concentration may be effected by adsorption on "Permutit" or charcoal or by high vacuum distillation ; (2) Sardine meal is extracted with isopropyl ether, dried, moistened with water and putrefied at 35‹C. for two or three weeks ; the product is dried and extracted with petroleum ether, the residue being caused to putrefy a second and subsequently a third time ; the extract is adsorbed on Decalso and desorbed by petroleum ether and benzene-petroleum ether, yielding vitamin K  2 .
