Title: Improvements relating to the production of sheets of organic film-forming substances
IPC: B29D7/01
Filed: 1941-06-06
Abstract: 549,929. Films, sheets &c. ; moulding plastic substances. ROONEY, J. H., LOCKE, R. S., and HAWTIN, P. R. June 6, 1941, No. 7192. [Class 2 (ii)] [Also in Group V] Thick sheets are obtained by depositing a solution of an artificial non-elastic film-forming polymer in a volatile solvent on a preformed sheet of the polymer laid on the smooth surface of a rigid support, which is thinly and evenly coated with a composition adapted to prevent adhesion of the preformed sheet to the support, evaporating the bulk of the solvent, stripping the resulting sheet, incorporating the preformed sheet, from the surface of the support, and evaporating substantially all of the remaining volatile solvent. The polymer may be a cellulose ester such as cellulose acetate, a cellulose ether such as ethyl or benzyl cellulose, polyvinyl alcohol, chloride, acetate, or chloracetate, polymethyl methacrylate, or polystyrene. The support may be of glass or metal and it may be coated with mineral oil, castor oil, olive oil, petroleum jelly, soap, or ester of a soap-forming acid. The preformed sheet may be one which has been made by casting one or more layers of dope. Preferably several layers of dope are cast upon the preformed sheet until the desired thickness of the resulting sheet has been attained. In an example, a solution of cellulose acetate is cast on a flat polished glass plate and after most of the solvent has been removed, a second layer is cast upon the first layer. The process is repeated several times and then the sheet so formed is stripped. The glass plate or a similar glass plate is then provided with boundary walls terminating in flat outwardly-projecting flanges. The space within the walls is filled with mineral oil. The preformed sheet is then laid flat on the oil layer and adhesively attached along its edges to the flanges on the walls. Twelve further layers of dope are then deposited on the sheet, each layer being partly dried before depositing the next layer. A sheet of 0.16 inches thickness may thus be built up. It is stripped from the plate and then exposed to a current of warm air to remove residual solvent. The dope may contain plasticizers and fire-proofing agents. Several sheets may be made at the same time by flowing dope continuously on to a series of casting plates moving past the casting point. After stripping each plate, lubricating the surface and replacing the preformed sheet, the final sheets may be built up by continuously flowing dope on to the series of preformed sheets each carried on the lubricated surface of its plate. Transparent colourless sheets suitable for use as observation panels of aircraft,wind shields, and the like may be made. Opaque or coloured sheets may be obtained by incorporating dyes, pigments, and effect materials in the dope. Specifications 533,788 and 542,080 are referred to.

Filed: 1946-03-08
Abstract: 606,007. Frequency and phase modulation. RADIO CORPORATION OF AMERICA. March 8, 1946, No. 7305. Convention date, Sept. 7, 1945. [Class 40 (v)] From a received angle-modulated wave a frequency discriminator derives a pair of waves whose relative amplitudes are dependent on the instantaneous frequency, and the respective waves are applied to separate rectifiers which are so poled as to form a single D.C. path, for the resulting unidirectional current. As shown in Fig. 1, the I.F. wave is applied at S to a phasing discriminator comprising tuned circuits 5, 12, and the resulting pair of waves is applied to the cathode 20 and anode 21 of reversely-poled rectifiers 13, 14. The separate I.F. paths through the rectifiers are completed through condensers 25, 26, and a single D.C. circuit through both rectifiers is completed by a resistance 30 shunted by a large condenser 24 which has negligible reactance at modulating frequencies. Demodulated signals are taken off between earth and the conjunction 32 of the condensers 25, 26. The earth point may be as shown at 31, or the mid-point 30 of the resistance 27 may be earthed and connected to the junction of two condensers replacing the condenser 24, Fig. 2 (not shown). In Fig. 7, condensers 101, 102 are interposed between the discriminator and the rectifiers 13, 14 and a further pair of rectifiers 108, 109 are provided, the D.C. circuit including all the rectifiers in series. For avoiding signal distortion when the input amplitude is high, resistance may be connected in series with the condenser 24 or with each condenser when two in series are used, Figs. 8a and 8b (not shown). Specifications 489,094 and 602,846 are referred to.

Title: Improvements in or relating to the manufacture of magnetic materials
IPC: C04B35/26
Filed: 1947-03-19
Abstract: In the production of fine grained porous ferro-magnetic ferrites containing manganese by sintering a mixture containing the oxides of manganese and iron, the cooling of the sintered product is effected in an atmosphere, the oxygen partial pressure of which decreases with decreasing temperature.  This may be effected by employing a nitrogen-oxygen atmosphere, the oxygen being obtained by electrolysis and the current being decreased with decreasing temperature of the ferrite, or by cooling in an atmosphere of superheated steam and inert gas when the dissociation of the water vapour will be proportioned to the temperature of the ferrite.  According to an example, manganese oxide, zinc oxide and ferric oxide are ground, moulded and sintered in an atmosphere of superheated steam at 1250 DEG C for 2 hours and cooled in the same atmosphere.  Specification 655,666 is referred to.

Title: Improvements relating to the removal of sulphur from molten nickel-containing masses
IPC: C22B9/10
Filed: 1944-04-26
Abstract: In a method of removing sulphur, and selenium and tellurium if present, from molten nickel-containing masses the mass is covered with a fluoride-containing slag and a treating-agent soluble in the mass and consisting of or containing one or both of calcium and magnesium is introduced into the mass beneath the slag and maintained there long enough for part of the sulphur to enter the slag, usually for a period of at least 5 minutes and less than 1 hour.  The slag is then removed from the surface of the mass. When the mass contains more than 0.2 per cent. of sulphur the treatment may be repeated with one or more further slags and treating-agents.  In this case it is preferred to use an initial treating-agent containing magnesium and a final agent containing calcium.  Sufficient magnesium-containing treating-agent us used to provide at least one part of magnesium for each part of sulphur to be removed and sufficient calcium treating-agent is used to provide at least five parts of calcium for each four parts of sulphur to be removed.  After the last treatment further refining may be carried out to free the mass from the treating-agent, or the final stage of sulphur removal may be done by cerium or a cerium containing agent.  Preferably the mass while under treatment contains at least 0.25 per cent. of manganese.  A suitable slag consists essentially of lime and calcium fluoride, preferably in proportions of 40-60 per cent. of each.  The process is particularly applicable to masses in which nickel is the predominant metal.  The treatment of alloys containing 10-50 per cent. copper and 50-90 per cent. nickel, of alloys containing 0.5-35 per cent. chromium and 50-90 per cent. nickel, and of alloys containing 1-20 per cent. manganese and 80-99 per cent. nickel is referred to, and also the production of an alloy containing 66.9 per cent. nickel, 29.5 per cent. copper, 0.005 per cent. sulphur, 0.18 per cent. carbon, 0.11 per cent. silicon, 1.83 per cent. manganese, 1.47 per cent. iron and 0.026 per cent. phosphorus.
