Title: Sand bath which operates fully automatically
Inventor: BIHLMAYER HANS-DIETER
IPC: A01K13/00
Filed: 1982-05-04
Abstract: The sand bath which operates fully automatically is used in animal breeding - primarily for the breeding of chinchillas. The sand bath consists of a cylindrical container which is divided into 2 chambers (chamber "A" being a storage container for the bath sand and chamber "B" a bath space) and is provided with a slot in the longitudinal direction. The partition is provided, to the extent of about 1 DIVIDED 3, with a sieve. As a result of a rotation through 180 DEG , the sand falls from chamber "A" through the sieve into chamber "B". After a second rotation through 180 DEG , the sand falls back through the sieve into chamber "A". The dirt present (droppings and litter) remains in front of the sieve and then falls through the slot out of the container into the droppings tray standing on the floor of the cage. The sand bath is attached within the cage by means of suitable fittings. By connecting a plurality of sand baths via a chain wheel and chain, as many sand baths as desired can be driven simultaneously. The drive may be manual or by means of an electric motor.

Title: Process for the preparation of homopolymers and/or copolymers of vinyl chloride
Inventor: MACHO VENDELIN DIPL ING DR
IPC: C08F2/18
Filed: 1982-06-11
Abstract: The invention relates to a process for the preparation of homopolymers and/or copolymers of vinyl chloride with olefinically unsaturated comonomers which have only a low content of defective particles, so-called fish eyes, or none at all, by free-radical suspension homopolymerisation and/or copolymerisation at from 5 to 80 DEG C, in general in a suspension using assistants. According to the invention, the process is carried out by exposing the reaction space, before the starting materials are added or at least before the polymerisation initiator or an initiator mixture is employed, to the action of at least one polymerisation inhibitor and/or at least one antioxidant, i.e. phenols, sulphur dioxide, hydrogen sulphites and the like. These substances are then preferably removed from the reaction medium, the necessary reaction components are added, the reaction conditions are established and the polymerisation and/or copolymerisation of vinyl chloride is then carried out. When the polymerisation is complete, inhibitors or antioxidants are added, if necessary, and the suspension is worked up.

Patent DE-3242708-A1 (DE)
Title: Single shaft screw extruder
Inventor: HENSEN FRIEDHELM DR ING
IPC: B29C48/50
Filed: 1982-11-19
Abstract: A screw extruder for processing polymeric plastics is described, which consists of a screw (2) with several processing zones (10 to 15) and a cylinder (1) with several sections (3 and 7 to 9), the length of which cylinder is matched to the length of the screw (2). The combination of measures to increase especially the flow of solid materials in the feed zone (10) is essential, e.g. the use of a replaceable grooved bush (4), and a shearing and mixing zone (12), which is described in detail, at the end of the compression zone (11), in which annular elements (18; 19), which are mutually supporting at their face sides, on the screw and in the related cylinder section cooperate in a special manner. Varied shearing and dispersion of the material flow, which is under the pressure of solid transport and enters into the mixing and shearing zone in a semiplastic state, achieves complete plastication thereof and extremely fine distribution of the components contained in the material flow. Each annular element (18; 19) has a plurality of chambers (21; 27) distributed on its interior and/or exterior circumference, which chambers are enclosed by helically extending, radial shear webs and axial delimiting webs (23; 29), so that the material flow is deflected several times in an approximately sinusoidal manner with mutual overlapping of the annular elements (18; 19) in the shearing and mixing zone (12) of the extruder in the direction of flow. With opposite pitch of the groove system, i.e. directed against the transport direction, the annular elements (18; 19) act in the sense of baffle elements. Any desired combinations are possible. <IMAGE>

Title: Method and device for forming the angle and/or angular velocity of a converter-powered drive
Inventor: BEST JOERG DIPL ING
IPC: G01P3/489
Filed: 1982-11-26
Abstract: In this method for determining the angle (.) or the angular velocity ( omega ) of a converter-powered drive, a digital pulse generator (1) is provided which upon rotation of the drive transmits generator pulses (P(t)) to a pulse counter (3). The pulse counter determines the number of the generator pulses (n) arriving in a prescribed scanning interval. Using extrapolation methods, the angle during the period (tr) between the end of the scanning interval and the last preceding generator pulse is additionally formed and added as correction quantity to the counting information (Z0) of the pulse counter (3), which is weighted in accordance with the angular or phase increment (.i) of the pulse generator (1). The result of the very precise measurement of angle or angular velocity thereby achieved is a good true-running characteristic of the drive even at low rotational speeds. <IMAGE>

Patent DE-3302967-A1 (DE)
Title: Open-fire heating system having multiple functions
Inventor: KERKHOFF PAUL
IPC: F24B1/18
Filed: 1983-01-29
Abstract: The innovation for the first time makes possible the combination of an open fireplace 2, an open fireplace closed with a door 3, with integration of the main heating system 4, for liquid, gaseous or electrical energy, where only one heating medium system 7, a flue gas duct 8 over a closure flap 9, and only one chimney flue are required from a technical point of view. If this system is installed in domestic utility rooms, radiant heat is not lost. Heated rooms having expensive multiple installations with large heat losses, and also additional chimney flues, are done away with. Solid fuels heat the heating medium 7 behind the combustion-chamber or walls 5, in the fireplace 2 or 3, which is open or closed with a door. The integrated main heating system 4 heats the heating medium 7 via its surrounding walls, and also by upwardly directed heating and flue gas pipes 6 which open into the flue duct 8, above the closure flap 9, where the single chimney flue begins. The multiple function is automatically regulated by setting the closure flap, so that no gases, especially from the main heating system, emerge via the combustion chamber 2-3 either. <IMAGE>

Title: Method and device for increasing the efficiency of turbine processes
Inventor: BOESE FRIEDRICH-KARL DR RER NA
IPC: F25B15/00
Filed: 1983-08-01
Abstract: The present invention is intended to serve for at least partially exploiting the exergy of a heat accumulator normally at a technically unusable, high temperature level T1. For this purpose it is proposed to use an "exergy-receiving compressor", which utilises the temperature difference between the high temperature T1 and a technically usable temperature level T2, in order to raise heat from a low temperature level T3 likewise to a technically usable level T2. This is achieved, for example, by suitable design using a system similar to the principle of the absorption refrigerating machine. The sorption cycle, comprising expeller (1), restrictor (13), absorber (9), pump (11) and where necessary a heat exchanger system (12, 14) at functions in this as "exergy-receiving compressor". The efficiency of the conversion of heat into mechanical energy can be improved by this system. <IMAGE>
