Abstract: 1,248,104. Magnetic storage arrangement. SIEMENS A.G. 30 Sept., 1969 [1 Oct., 1968], No. 47902/69. Heading H3B. In a multi-layer magnetic storage arrangement, the various layers such as base 1, magnetic films 11-14, insulation 2, conductor patterns 3, 4 and keeper plate 5 are clamped together by gas pressure during use. The stacked layers are placed in a gas-tight chamber comprising plates 6, 16, and end pieces 7, and gas is pumped into the chamber via inlets 8. The gas acts on the base 1 and a flexible membrane 9 to clamp the layers. Alternatively, the inside of the stack may be evacuated, Fig. 2 (not shown), or both internal evacuation and external superatmospheric pressures may be used. It is stated that the application of pressure to one side only of the stack causes undesirable bending.

Title: Malting process
IPC: C12C1/15
Filed: 1962-12-27
Abstract: A malting process consists in increasing with controlled precision the moisture of the grain between the commencement of steeping up to the kilning stage, while maintaining the regularity of germination as required by the art, by a moistening treatment performed on a small quantity of the grain, e.g. 30 Kg., under the same conditions of temperature, oxygen and carbon dioxide as those which prevail during a germinating process of known type, in such a manner as to cause germination to commence as soon as possible with the minimum quantity of water.  The moistening treatment is carried out by sprinkling with water a fine layer of the grain not more than 3 cm. thick.

Abstract: 1482500 Independent rear suspensions VOLKSWAGENWERK AG 28 Nov 1975 [30 Nov 1974] 48939/75 Heading B7D In a rear suspension comprising on each side of a motor vehicle body 3 a longitudinal link 1, 2 and a spring strut 8 secured to a wheel carrier 9, the links 1, 2 are made from sheet steel and are interconnected near their forward ends by a steel strip 4 to form a one-piece horizontal sheet steel structure which is angularly rigid in a horizontal plane so the links 1, 2 can carry lateral loads. The links 1, 2 and the strip 4 may be stiffened by bands along one or both edges or by longitudinal corrugations. Bearings 5, 6 connecting the links 1, 2 to the body 3 are spaced in front of the strip 4 to produce a twisting effect on the links 1, 2 when the body rolls during turns which reduces the bending moments acting on the struts due to lateral loading of the rear wheels 10. Trunnions 7 which connect the links 1, 2 to the struts 8 or the wheel carriers 9 have inclined axes so that a change in camber results from upward deflection of a wheel.

Abstract: 1,216,276. Making liquor from cocoa beans. BRITISH FOOD MFG. INDUSTRIES RESEARCH ASSOCIATION. 22 April, 1969 [22 April, 1968; 17 Oct., 1968], Nos. 18832/68 and 49242/68. Heading A2B. A process for making a liquor from which chocolate, cocoa or cocoa butter is obtained comprises removing the husks from cocoa beans, grinding the remaining bean nibs to a liquor, feeding the liquor under pressure through a roasting chamber and ejecting the roasted liquor (e.g. in the form of droplets or thin sheet) into a vented collecting chamber. The liquor may be continuously stirred in a steam jacketted roasting chamber and heated to 130-160C. The collecting chamber may be maintained at partial vacuum by drawing air through it, the air entraining the escaping unwanted vapours from the roasted liquor. Before grinding the moisture content of the nibs may be reduced to about 20% by wt. and cocoa fat added to the nibs. The liquor may be recirculated through the roasting and collecting chambers or passed through a succession of these chambers.

Abstract: 1,088,898. Reactors. NUCLEAR POWER PLANT CO. Ltd., and A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd. Aug. 17, 1966 [Nov. 19, 1965], No. 49365/65. Heading G6C. In a light water cooled, heavy water moderated nuclear reactor, the moderator and coolant pressures are maintained equal. The fuel tubes in the moderator calandria tank are not subjected to pressure and a minimum thickness of neutron absorbing material is employed. The tank is mounted within a concrete pressure vessel and immersed in light water coolant which is circulated by pumps mounted in the concrete wall. Steam is passed through a separator within the vessel and leaves through a Venturi which prevents an excessive steam loss, by the generation of sonic velocities, in the event of a fracture of the steam system. The equalization of the pressures of the moderator and coolant is effected by maintaining a vapour space above the moderator in the calandria tank. Alternatively, helium gas may be admitted to the calandria through valves controlled by the pressure difference across the calandria walls. Deuterium may be used instead of helium and pressure may be controlled by regulating the flow of heat from the fuel to the moderator by thermal insulation.

Title: Terephthalic acid recovery
IPC: C07C63/26
Filed: 1964-12-10
Abstract: Terephthalic acid is recovered from a liquid reaction mixture obtained by the catalytic oxidation of a para-disubstituted benzene in the liquid phase with molecular oxygen in acetic acid as reaction medium by heating the liquid phase reaction mixture to 500 DEG  to 600 DEG  F. under a pressure sufficient to maintain a liquid phase of acetic acid sufficient to dissolve all the solids present, cooling the mixture to 300 DEG  to 350 DEG  F. under pressure sufficient to maintain a liquid acetic acid phase to crystallize out terephthalic acid, separating the terephthalic acid crystals at 300 DEG  to 350 DEG  F., washing the crystals with acetic acid and drying the washed crystals. Specified starting materials are p-dialkylbenzenes and p-alkyl-benzoic acids.  The catalyst preferably comprises bromine and a heavy metal oxidation catalyst of A.W. 50 to 200, e.g. cobalt or manganese.  The weight ratio of acetic acid to p-xylene in the starting mixture is 1 : 1 to 10 : 1 and when the ratio is less than 6 : 1 addition acetic acid is added prior to heating to 500 DEG  to 600 DEG  F. so that acetic acid is present in amounts of 6 to 10 parts by weight per part of total solids.  The term total solids is defined. The terephthalic acid crystals have an average diameter not exceeding 300 microns. Hydrogen may be introduced into a reactive mixture which contains catalytic amounts of Co or Mn during the heating step to cause hydrogenation of 4-carboxybenzaldehyde.

Abstract: 1,218,690. Control circuits for resistance welding apparatus. SIEMENS A.G. 17 Oct., 1969 [19 Oct., 1968], No. 51220/69. Heading H2H. A monitoring arrangement for indicating the passage of a sufficient welding current for a desired time includes a voltage measuring transformer, a pulse shaper, and an integrating amplifier. In the arrangement shown, a phase angle controlled switch 15, which may be an antiparallel pair of thyristors or thyratrons, regulates the power supplied to a welding transformer 1. The primary winding of a monitoring transformer 5 is connected across the primary 2 of the welding transformer, and the output from the transformer 5 is fed through a rectifier 16 to a pulse shaper 6. In operation, square pulses from the shaper 6 are supplied to one input of an AND gate 7, the other input 72 being energized provided current is flowing in the welding circuit. Thus, pulses enter a feedback amplifier 8, 9 and are integrated, the steadily increasing amplifier output being fed to a limit-value device 10 which emits a signal when its input reaches a predetermined level. This signal may be used to terminate the welding operation. A device 13, which discharges the feedback capacitor 9, may be used to regulate the rate of rise of the amplifier output. The amplifier is reset before each welding operation, and the arrangement is particularly suited to the monitoring of each of a succession of spot welds.
