Title: Process for the Production of Formaldehyde.
IPC: C07C45/38
Filed: 1967-09-20
Abstract: 1,154,058. Formaldehyde. PERSTORP A.B. 20 Sept., 1967 [27 Sept., 1966], No. 42779/67. Heading C2C. Formaldehyde is produced by the oxidation of methanol with a surplus of air in the presence of a metal oxide catalyst, the air being preheated in a co-current heat-exchanger by the hot gases from the reaction. The methanol may be first evaporated and preheated, e.g. by steam in a counter-current heat exchanger, and then mixed with the heated air, or evaporated by the heated air in an evaporator, with subsequent re-heating of the gas mixture if necessary, or may be injected straight into the hot air stream. The temperature in the reactor is regulated in the usual way with a heat transfer medium, itself cooled in a heatexchanger and the surplus heat used to generate steam. After cooling in the co-current heat exchanger, the reaction gases are passed to an absorption system for absorption of the formaldehyde, e.g. in water.

Title: Method of producing steel ingots
IPC: B22D27/06
Filed: 1975-10-20
Abstract: 1495688 Casting ingots CENTRO SPERIMENTALE METALLURGICO SpA 20 Oct 1975 [11 Nov 1974] 42928/75 Heading B3F In a method of casting large ingots, e.g. 150-200 tons, molten steel is poured into a mould and an electrically conductive molten slag covering is applied to the surface of the molten steel and, during an initial stage of solidification, heat is supplied to the slag to maintain it and the uppermost layer of the steel in a molten condition and no additional molten steel is added whereby the level of the molten steel in the mould is allowed to fall, and wherein during a subsequent stage of solidification of the ingot molten steel is added which contains a progressively decreasing quantity of segregating elements and the rate of addition being such as to restore the original level of molten steel and then maintain the said level of the melt substantially constant. In the initial stage the heat is supplied by using an electrode and generating a current through the slag to the mould without consuming the electrode. In the subsequent stage the current density is increased to melt the electrode and so add molten steel to the mould. The electrode is constructed to have a varying proportion of segregating elements along its length. When more than 90% of the ingot has solidified a final stage of solidification applies wherein the rate of generation of heat is reduced and the addition of further molten steel is tapered off to zero. The mould employs a hot top which contains the slag and molten steel level and is tapered upwards in its internal cross-section to a reduced parallel sided section of 25-50% of the crosssection area of the part immediately adjacent the mould. The method may take place in a protective atmosphere or in a vacuum.

Abstract: 880,054. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORPORTION. Dec. 29, 1959 [Dec. 30, 1958], No. 44D75/59. Class 100(1) In apparatus for feeding sheets, such as cheques of varying dimensions, to a scannning device the sheets are conveyed along a curved path by a first curved conveyer and urged sidewise against a moving side guide, and then along a second curved path by a second conveyer which is positioned to receive the sheets from the first conveyer. As shown, sheets from a separating apparatus are fed singly by a driving belt or roller 92 and a roller 93 along guides 90, 91, and between a curved guide 62 and the contiguous curved surfaces of a fixed plate 22 and a rotating drum 12, 19. When the leading edge of a sheet engages a driven roll 74 on the plate 22 and an idler roll 80 in the form of a castor, the latter urges the sheet sidewise against a shoulder 21 on the drum 19. The registered sheet is fed forward beneath a curved guide 64, between a second castor roll 86 engaging the drum surface 19, and on to the surface of a rotating drum 14 where it is gripped and held to that drum by a belt 44 which engages the sheet along the side edge opposite the edge which has been aligned. The sheet is guided smoothly from the drum 19 to the drum 14 by the tangential edge 30 of a guide flange 28 on the fixed plate 22, the tangential edge portion 65 of the guide 64, and the belt 44. The sheet is now scanned by a pair of magnetic heads 98, 99, there being soft rubber rollers 94, 95, mounted on the vertical baseplate 10, opposite these heads to help to support the sheet, and a third guide 70. The sheet is then delivered by the belt 44 and further spaced belts, such as 51, around the roller 45 and between guides 100, 101. The castor roll 80 is swivel-mounted in a post 83, is urged towards, the roll 74 by a spring; and is urged towards the plate 10 by a spring 84. The second castor roll 86 is similarly constructed and mounted. The drum 12, 19 is driven by a belt 32 which engages a flange 20 on the drum periphery and is passed over rollers 33, 34, 35. The belt 44, mounted on rollers 45, 46, drives the drum 14, and a belt 78 driven by the drum 14 drives the roller 74. The roller 74 is of nylon material, and the drum 14 has a rubber periphery 17.
