Abstract: 986,094. Moulding processes. QUAKER OATS CO. Feb. 3, 1964, No. 4431/64. Heading B3F. A foundry moulding process comprises forming a foundry composition by mixing together sand, an aqueous acid solution, and an acid catalysed polymerizable binder, the acid in said solution being present in sufficient quantity but insufficient concentration to trigger rapid polymerization of the binder, forming the composition into shape, and increasing the concentration of acid by removing water from the solution in a uniform manner at least until said acid is sufficiently concentrated to trigger rapid polymerization of the binder. The water may be removed by blowing through heated or unheated air or inert gas such as N, or by application of a vacuum. The binder, present in about 1-6 parts by weight of the sand, may be furfuryl alcohol and low viscosity polymers thereof, furfuryl alcohol-formaldehyde, furfurylated urea, urea formaldehyde, -phenol formaldehyde and furfuryl alcohol-phenol-formaldehyde resins. Catalysts include sulphuric, phosphoric, dodecylobenzene sulphonic, maleic, trichloroacetic, and Lewis e.g. ferric chloride, acids.

Abstract: 1,182,431. Alkaline secondary cells. ALKALINE BATTERIES Ltd. 30 Jan., 1968 [30 Jan., 1967], No. 4540/67. Heading H1B. An alkaline secondary cell has a case 25 containing the plates 10, 11, separating means between plates of opposite polarity and sufficient electrolyte to flood the plates and separating means, the upper parts of the plates are mounted in a compartment 26 which is closed at the top and communicates below the electrolyte level with an expansion space into which the electrolyte is forced when gases are evolved, so depressing the free liquid level below the tops of the plates, the separating means between certain areas of plates of opposite polarity being absorbent so as to provide effective conduction between the plates even when the free electrolyte level is depressed, while the separating means between other areas are such that, when above the free liquid level, they leave a clear path for gas to flow between plates of opposite polarity. Gases evolved are thus able to reach the plates and be absorbed by them. As shown, the separating means 17 on one side of a plate are absorbent whilst pin or rod separators 15 on the side allow free flow of gas. Alternatively, only one kind of separator, made of absorbent material, is used, but it is arranged so as to leave corresponding areas of neighbouring plates exposed. For example, the absorbent separators may be of tape form wound in flattened helices round each to alternate plates (Fig. 3, not shown).

Title: Improvements in or relating to the production of semi-conductor arrangements
IPC: H01L21/00
Filed: 1961-02-10
Abstract: 894,700. Semi-conductor devices. SIEMENS & HALSKE A.G. Feb. 10, 1961 [Feb. 12, 1960], No. 5068/61. Class 37. In the production of a semi-conductor device, a gaseous compound of a semi-conductor is decomposed to deposit a layer of semi-conductor on to a heated semi-conductor body which is placed on a carrier body of semi-conductor material. The arrangement avoids harmful effects which may arise from the use of other material for the carrier body. Fig. 1 shows a silicon carrier body 1 supported between electrodes 8 and 9 in a reaction chamber. Silicon discs 2-7 are placed on the body 1 which is heated to decompose a reaction gas such as silicochloroform with hydrogen and possibly including a gaseous compound of a doping substance, whereby a semi-conductor of different resistivity or conductivity type is deposited on the silicon discs. The electrodes are preferably covered with silicon. Heating is effected by passing current through the carrier body firstly by using a high-voltage source and then a lower voltage as the temperature rises and resistivity falls. In an alternative arrangement heating is effected by use of an induction coil. High and low resistivity layers may be produced and may be used to provide diode rectifiers, solar cells, variable capacitors and transistors. Germanium may be used in place of silicon.
