Patent DE-2063548-A1 (DE)
Title: Continuous classification unit for bulk goods - for industrial purposes
IPC: B07B1/28
Filed: 1970-12-23
Abstract: The unit consists of classification sieves held in a housing, and a vibration exciter.

The unit allows the goods to remain longer on the classification surface, which results in increased selectivity, and improved classification.
Patent DE-2136672-A1 (DE)
Title: Washing and cleaning compsns - contg as builders water-soluble salts of polymeric alpha-hydroxy or alpha-amino-acrylic acids
Inventor: WEGEMUND BERND DIPL CHEM DR
IPC: C11D3/37
Filed: 1971-07-22
Abstract: Title polymeric cpds. (polycarbonates) are used fully or partly instead of tripolyphosphate builders, which recently became objectionable because of promoting bis-contamination of effluents; the effectiveness of the compsns. is not diminished. Apart from the polycarbonates, the compsns. contain anionic, amphoteric and/or non-ionic surfactants and other conventional components. The polycarbonates are produced in the known manner by reacting an alpha, beta-dihalogenopropionic acid or its ester in an aq. medium with a base selected from hydroxides, carbonates, acetates of alkalis (esp. Na), ammonium opt. substd., and amines. Sodium poly-alpha-hydroxyacrylate is pref. The compsns. can be used for washing (e.g. hand or in machines) and/or bleaching textile materials; cleaning appts., vessels, hand surfaces of all types (ceramic, glass, metals, polymers, wood, etc.).
Patent DE-2155204-A1 (DE)
Title: Measurement of breeder factor and reactor power - in a fast reactor
IPC: G21C17/108
Filed: 1971-11-06
Abstract: Determination of breeder factor and reactor power by means of probes consisting of fissile material amalgams distributed in a precise geometric pattern in a fast reactor core. The probes are made as small as possible so as not to impair core parameters and the fissile amalgams may be typically U235 U238 or U233 Pu241 with Th232 and are clad in Nb Th or Cr to ensure maximum fast neutron capture. Use of fissile amalgams ensures a greater number of fast neutrons of different resonant frequencies will be captured and thus a more representative and effective measure of breeder factor adn reactor power will be obtained by monitoring of particle emissions when the probes are retrieved from the core after discrete time intervals.

Patent DE-2213370-A1 (DE)
Title: Gas/vapour treatment of conditioning agents - prior to electrostatic separation of minerals
Inventor: WIRRIES HEINRICH DR RER NAT
IPC: B03C7/00
Filed: 1972-03-20
Abstract: Conditioning agents (e.g. o-cresotic acid, salicylic acid) used for the preliminary chemical treatment of mineral mixtures, esp. of crude K-salts, before electrostatic separation, are subjected to acidic or basic gases or vapours before use. The separation thereby requires less conditioning agent. The treatment can be carried out with a single gas/vapour, mixtures or several cpds. applied successively. The gas/vapour state (if not existing under normal conditions) is attained by reduced pressure or elevated temp. The conditioning agent can be in pure form as a mixture, in soln. or on a carrier.
Patent DE-2240930-A1 (DE)
Title: Purgative agent from linseed and rhubarb
Inventor: HADHANYI ANDREAS DIPL CHEM
IPC: A61K36/55
Filed: 1972-08-19
Abstract: A purgative agent is produced by soaking linseed in the expressed juice of rhubarb leaves which has previously been briefly heated to ca 55-90 degrees C, cooled, adjusted to pH 6.0 and treated with pepsin; bringing the soaked linseed to germination in a conventional manner; and drying and crushing the germinated linseed. The prod. has improved purgative activity, but gives rise to no side-effects; no HCN is released under physiological conditions, since linseed glycosidases are inactivated by the pepsin used in the prodn. of the new prod.
Patent DE-2336716-A1 (DE)
Title: Casting of stacks of filled polyester sheets - with decoratively structured surface by casting onto film glued to base
Inventor: KIRSCHBAUM JOSEF
IPC: B44C3/02
Filed: 1973-07-19
Abstract: Surface-structured panels of quartz-flour filled pigmented polyester are mfrd. by casting the polyester casting cpd. onto thin (0.025-0.050 mm) thermoplastics film which is glued to a base plate by means of a polyester adhesive. By wetting the underside of the film with polyester, the film crinkles into corrugations which are stabilised dimensionally by being glued to the base so that a low-profile, random structure results. Surprisingly, the film undergoes a chem. modification enabling polyester panels with dry surfaces to be cast which are sticky in the structural depressions. Dry metal powder may be deposited in the depressions giving a metallic pattern in the coloured structure.

Title: Dyestuff absorbence measurement system - has a dwell tube in a photo-electric light beam with comparison circuit for generated signal valves
Inventor: STURM WALTER
IPC: D06B23/28
Filed: 1973-12-17
Abstract: The system to control the absorption of separate or combined dyestuff components, by modifying the dyestuff temperature, uses a light beam passing through a tube which is periodically filled with dyestuff by a valve to dwell sufficiently for photo-electric assessment, for the generated signal to be stored for comparison with a preset factor for the temp. to be modified if there is a variation beyond the required tolerance. The system ensures that the translucence of the dyestuff, and the passage of the light beam through it, is converted into an accurate reading for use in temp. control to regulate the dyestuff absorbance.

Title: Labelling machine label transfer mechanism - has transfer roller driven by bolt working in radial slot
Inventor: WOHLMANN WILFRIED DIPL ING
IPC: B65C9/12
Filed: 1974-11-04
Abstract: A roller equipped with suction cups or grips performs a pilgrim-step motion between stationary hopper and rotary labelling drum under the action of a planetary gear train, to transfer the labels. The roller is supported on a housing and coupled in the axial direction to a driving wheel with a radial slot. In this a bolt works, solidly mounted on a lever on the planetary gearwheel, which meshes with a stationary sun wheel in the housing, thus imparting a sinuous epicycloidal motion to the bolt. Sun wheel and planetary wheel are of the same diameter, their axes being coupled by a bar. The sun wheel axis also acts as the shaft, supported in the housing, of a gear, and as an eccentric underneath the housing causing the latter to rock on the machine frame. The gear meshes with another gear driven from the labelling machine.
