Title: Binder-free sand moulds compacted by suction - where prefabricated mould sections are inserted in moulding frame
Inventor: GROLLA HERBERT
IPC: B22C9/03
Filed: 1975-01-21
Abstract: Process for embedding a prefabricated mould-section, e.g. a sprue or riser, in the losse, binder-free sand of a mould made using a thin foil pattern and sand compacted by sub-atmospheric pressure. The novelty is that the mould-section, e.g. a bush, is temporarily clamped on the bottom of a plate beneath a dosing device used to fill the mould with sand, so that when the doser is placed on the moulding frame the bush is aligned with a channel formed by the pattern; after filling the frame with sand the doser outlet is closed and the clamp holding the bush released so that when the doser is removed the bush remains in the mould; more than one mould-section may be located in this manner. The pref. device uses suction to hold the mould section(s) on the doser.

Title: Washing system for textiles - contains fabric impregnated with solid polymeric cation exchange resin as builder
Inventor: HENNING KLAUS DIPL CHEM DR
IPC: C11D3/37
Filed: 1975-07-26
Abstract: Textiles are washed in the presence of a flat water insoluble solid cation exchanger having a calcium binding capacity of more than 5 g Ca/100 g exchanger. The cation exchange material is made by (1) impregnating a flat fibre sheet with solns. or dispersions of carboxyl gp. contg. polymers, (2) removing the solvent or dispersing agent and (3) opt. converting the COOH gp. into the alkali- or ammonium form. The exchangers can be made in the form of impregnated fabrics which can be used in conjunction with known washing agents in place of or as a supplement to standard builders. The exchangers have a good capacity for binding the hardness of the water, cause dispersion of dirt particles in the water, and stabilise dissolved dirt in the wash water, inactivate mineral components in the wash water, and reduce adsorption of the surface active material into the fibre. Ecological problems caused by known builders in waste water are avoided. In am example, an impregnated fabric was made by immersing a non woven polyester fabric in a dispersion of an acrylic acid/tert. butyl acrylate/divinyl benzene styrene copolymer and drying at 80 degrees C. The material was neutralised with 1 N NaOH to give a prod. with excellent binding capacity for calcium.

Inventor: BAUSER HERBERT DIPL PHYS DR
IPC: G01T1/14
Filed: 1976-08-06
Abstract: The parent patent describes a dosimeter, in which gas-filled chambers contain an electrical field produced by electrets; the ionising radiation to be measured produces charge pairs in these chambers and these charge pairs are sepd. by the electrical field. Equipment is also provided for measuring the electrical charge. In this addition the device comprises two ionisation chambers, sepd. by a movable electret disposed between two electrodes; the respective distances between these two electrodes and the electret are variable; the charge flowing from one electrode to the other via an interconnecting line as the electret is moved is used for the purpose of determining the distance between the ions charges produced in the two ionisation chambers and thus for evaluating the radiation dose to be measured. Used partic. for monitoring persons subject to radiation in laboratory work or nuclear power plants. The background signal produced by the electret charge can be eliminated, thus reducing the min. threshold of the measuring range achievable by the instrument.
