Patent DE-2916668-A1 (DE)
Inventor: HAMBRECHT JUERGEN DIPL CHEM DR
IPC: C08L25/12
Filed: 1979-04-25
Abstract: Molding materials containing styrene-acrylonitrile copolymers, in which an additional essential ingredient is from 0.1 to 2.0% by weight, based on the copolymer, of a three-block polymer X-Y-X, where X is a terminal ethylene oxide block and Y is a central propylene oxide block. The proportion of terminal ethylene oxide blocks X, based on block copolymer, is from 5 to 20% by weight, while the central propylene oxide block Y has a number-average mean molecular weight of from 700 to 3,000 and its proportion is from 80 to 95% by weight, based on block copolymer. The number-average molecular weight of the sum of the two terminal blocks X is from 140 to 1,000. The novel molding materials may be used for the manufacture of moldings, since the three-block copolymer X-Y-X advantageously influences the processing characteristics of styrene-acrylonitrile copolymers, and in particular broadens the range of conditions under which they may be injection-molded, without adversely affecting the mechanical properties of the styrene-acrylonitrile copolymers. Accordingly, the injection molding scrap rate can be kept very low.

Title: Mixer for particulate solids - having cylindrical body with mixing elements of wedge shaped profile attached to central rotating shaft
Inventor: HOLZMUELLER REINHOLD DIPL ING
IPC: F26B11/16
Filed: 1979-10-19
Abstract: Particulate solids are mixed in a horizontal cylindrical or trough shaped vessel which has an inlet and an outlet for the solids and an inlet for liq. or drying air etc. Solids are agitated by a stirrer consisting of a number of blades on radial arms projecting from a central shaft. Blades of the stirrer rotate close to the wall and they have a wedge shaped profile. Sharp edge of the wedge moves parallel to the cylinder wall, and is located at the max. radius of the blade from the axis. Mixer can be used to mix various particulate solids together, to mix liqs. into them or to mix them with a gas such as air. The mixer loading is raised for a given vol., giving more intense agitation of the solids coupled with better and more uniform contact with a drying medium such as air.

Title: Miniature railway system - has two-part insulated rail permitting several separately controlled trains on same pair of rails
Inventor: SCHELLONG GERHARD
IPC: A63H19/24
Filed: 1980-04-16
Abstract: The system incorporates into a pair of rails, three independent drive and/or control circuits including a common return line. This is achieved by splitting each rail longitudinally into two parts and rebonding the parts with an intermediate insulating layer (1). The wheel flanges may be gently pressed outwards against the inner side of the rails to make good contact and thus conduct the drive or control currents. Alternatively, separate sliding contacts may be provided. On the basis of the 'multi-circuit rail' various design combinations become possible with the object of arranging on a single toy rail line the running of more than one train at different speeds, for example for putting together a combination of wagons on a shunt yard, by remote control.

Patent DE-3036515-A1 (DE)
Title: Permanent radioactive waste store maintained at constant pressure - always below lowest barometric pressure thus reducing pump and filter costs
Inventor: BRENDER ROLAND
IPC: G21F9/24
Filed: 1980-09-27
Abstract: A method for the controlled supply and return ventilation of inaccessible cavities for the storage of harmful waste, esp. radioactive waste, consists of maintaining the pressure in the cavity below the minimum barometric pressure and keeping it constant by absolute pressure control. Pref. the absolute pressure control is maintained by the supply and return streams of the gas, esp. air, at least a part of the return stream being resupplied. Used in particular for the final, permanent storage of radioactive waste in underground storage cavities. By maintaining pressure always below the lowest occurring atmospheric pressure, the result is achieved that the air pressure in the cavity does not fluctuate. Consequently it is not necessary to draw out very large quantities of air amounting sometimes to several thousand m3 per hour, when the barometric pressure falls. In other words the air can always be in theory completely recycled and filtering of these large quantities of extracted air to adjust the pressure is no longer required.

Title: Ionisation fire detector circuit - has fault monitor releasing alarm when supply voltage or isolation of chamber drops
Inventor: BEYERSDORF HARTWIG DIPL ING
IPC: G08B17/11
Filed: 1980-02-08
Abstract: The ionisation fire detector has a measurement chamber (MK) connected inseries with a reference chamber (RK). Smoke (62) and fault (46) alarm circuits are connected to the junction (38) between the two chambers. The fault alarm circuit releases an alarm signal when the isolation resistance of the measurement chamber drops below a given value. The fault alarm circuit is designed so that its input voltage between its input and one d.c. supply pole (28,30) is almost independent of the d.c. supply voltage. This means that the circuit also produces an alarm signal when any fault occurs that effects the voltage across the measurement chamber. An alarm is therefore released when the d.c. supply voltage drops below a given level. The fault alarm circuit comprises two bipolar transistors, one FET and five resistors.
