Title: Metallised high-shrinking fibres having low surface-resistance - produced by activating fibres with colloidal palladium soln. and chemically plating from alkaline bath
Inventor: EBNETH HAROLD DIPL CHEM DR
IPC: D06M11/83
Filed: 1977-11-03
Abstract: High-shrinking, metallised filaments or fibres are produced by (a) activating high-shrinking filaments or fibres with a colloidal Pd soln. at room tepm. and then (b) treating with alkaline metal reducing baths at room temp. High-shrinking, metallised filaments or fibres obtd., having surface resistance max. 1 x 103 OMEGA, measured according to DIN 54345 at 50% RH and 23 degrees C, are claimed. The filaments and fibres are used for the prodn. of antistatically finished textile articles, and may be blended with other synthetic or natural fibres e.g. for floor covers, woven- or knitted fabrics. The surface resistance achieved are lower than those achieved on using ionogenic activating baths and acid metallising baths, e.g. 103 OMEGA compared with >106 OMEGA. Shrinking capacity is unimpaired by metallising. After shrinkage, surface resistance of fibres is hardly above that of the unshrunk fibres but at least 10x below that of C black-contg. fibres. On shrinking, textiles are free from dark stripes or mixt. effects.

Patent DE-2820728-A1 (DE)
Title: Throat gas purificn. plant for blast furnace - where gas drives turbine fitted on common shaft with asynchronous motor and compressor producing blast for tuyeres
Inventor: HEGEMANN KARL RUDOLF ING GRAD
IPC: C21B7/22
Filed: 1978-05-12
Abstract: Main patent described a plant contg. a driving motor for a compressor creating the blast fed to the tuyeres on the blast furnace. The throat gas leaving the furnace travels through a washing tower contg. a ring gap adjusted by a controller so the pressure of the throat gas can be kept at a prescribed value. On leaving the washer, the gas can be fed either through a by-pass, or through an expansion turbine creating electric energy. Specifically a single common shaft is used for turbine, an asynchronous motor, and the compressor creating the blast and the motor drives the compressor. With the main patent the turbine must be switched off during some phases of furnace operation, so the generation of electricity ceases. The present invention permits electricity generation to continue over a wide range of furnace operation.

Title: Low beverage soluble iron content filter aid - prepd. by treatment with tannic acid, gallic acid, or mixts.
Inventor: BRADLEY TIMOTHY GRAHAM
IPC: B01J20/14
Filed: 1978-11-18
Abstract: Method for the redn. of the beverage-soluble Fe (BSI) content of a diatomite or perlite filter aid (I) consists of the treatment of granular (I) with tannic acid (II) and/or gallic acid (III). Treated (I) have low BSI levels, but keep normal filtration and clarification properties. Thus beer, wine or fruit juices etc. filtered through treated (I) contain low Fe levels, and do not have shortened shelf lives or altered taste. In an example, diatomite (45-55 ppm BSI) was treated with 17% aq. (II) (3.3 lb of (II)/ton), when BSI levels were reduced by 70%.
Patent DE-2851870-A1 (DE)
Title: Temp. compensation for hollow microwave resonator - uses thin walled ceramic tube attached to metal carrier as compensating element
Inventor: BERNHARD HORST DIPL ING
IPC: H03L1/02
Filed: 1978-11-30
Abstract: Temp. compensation is provided for a hollow resonator. The cavity resonator (1), typically of brass, contains a ceramic rod (2) for tuning. The compensating element (6) is a thin walled ceramic tube, typically a few tenths of a millimetre wall thickness, attached to a metal carrier (7). The latter is normally a screw to allow accurate positioning for optimum temp. compensation. The tube gives a high ratio between compensation effect and electrical detuning of the resonator. Also the small active volume of the ceramic tube projecting into the cavity results in low losses and a negligible deterioration in quality. The effects of distortion only arise above 10GHz as the thin walls are not suited to dielectric conduction.

Title: Rubber system for gravity casting, esp. in sand moulds - where bottom end of vertical runner has perforated choke plate reducing turbulence in molten metal
Inventor: JEANNERET MIGUEL
IPC: B22C9/08
Filed: 1979-02-14
Abstract: The mould contains >=1 cavity and >=1 vertical runner extending downwards from the top surface of the mould or cope. The runner leads directly to the mould cavity, but its bottom end is fitted with a perforated plate. The plate followed the contour of the mould cavity and is stationary. The total area of the holes in the perforated plate is much smaller than the smallest cross-section of the runner, so the plate has a choking effect on the flow of metal and forms a head of metal in the runner. The plate is fixed in the upper part of the mould, and pref. consists of two different parts, one providing mechanical strength, the other resisting attack by the molten metal.
