Title: Use of waste for the production of fillers for plastic articles
Inventor: RIES WALTER ING GRAD
IPC: C08J11/06
Filed: 1981-12-18
Abstract: The use is proposed of aluminium/PVC waste foils, in particular from the pharmaceuticals industry, for the production of fillers for plastic articles, which can be pressed, extruded and injection-moulded. It is also possible to produce foils. The proportion of aluminium/PVC filler can be up to 90% by weight in pressed boards, in particular flooring boards for underfloor heating. In extrusion and injection moulding and in foil moulding, the proportion of aluminium/PVC filler is not above 50 and 60% by weight respectively. In addition to PVC and polyurethane, suitable binders are also polyester, polyethylene and polystyrene plastics. Additional inorganic and metallic fillers may also be present, in particular in the case of pressed boards. Aluminium/PVC waste foils can have binder properties in chipboard.

Title: Device for measuring rotary movements
Inventor: SCHMITT FRANZ-KARL DIPL ING
IPC: G01C19/66
Filed: 1982-10-11
Abstract: A device is proposed which senses rotary movements by using the Sagnac effect. For this purpose, a glass laser tube 6 is provided which generates two laser beams moving in opposition. The anode currents required for this purpose may have only a very small permissible difference. The circuit for regulating the anode currents consists of a linear controller 1 which keeps the current J1 at a constant value. The currents J1 and J2 are sensed via measuring shunts R1, R2, and a control amplifier is used in conjunction with differing currents to generate a signal which is fed to a relative linear controller 2 in order to match the current J2 to the current J1 Matching of the currents to a maximum difference of 1 is achieved by means of this dependent control of the current J2. <IMAGE>

Patent DE-3241740-A1 (DE)
Title: Zinc extraction process
Inventor: ESNA-ASHARI MOHAMMED DR
IPC: C22B5/16
Filed: 1982-11-11
Abstract: The invention relates to a process for treating sulphidic zinc ores by primary leeching at atmospheric pressure with battery acid in the presence of Fe<3+> ions and separating the liquor and the primary leeching residue. The primary leeching residue is dried and then treated in a smelting furnace and the liquor is subjected to a further treatment with a view to extracting zinc by subsequent electrolysis. The primary leeching residue is remelted to produce a dumpable slag and burning the elemental sulphur, an offgas being produced from which zinc is precipitated as zinc oxide. A problem presented by this process is the purification of the liquor in connection with a cost-effective approach to the entire process. The problem is solved, according to the invention, in that the further treatment of the separated liquor takes place in the following process stages: a) a crystallisation stage with the crystallising-out of Fe<2+> as FeSO4<.>xH2O from the liquor, b) separation of the filtrate, c) a precipitation stage for precipitating the remaining Fe<2+> by neutralisation and oxidation, d) separation of the filtrate, and e) a stage for purifying the filtrate to electrolysis purity. Particularly advantageous is oxidation of the Fe<2+> to Fe<3+> in the residue from the crystallisation stage and its return to the primary leeching. The invention makes it possible also to [lacuna] inferior sulphidic zinc ores and residue land fills with high contents ...

Title: Magnetostrictive ultrasonic transducer, particularly for very high frequencies and high power
Inventor: PODGORSKI JAN DIPL ING
IPC: B06B1/08
Filed: 1982-12-08
Abstract: The present invention describes a magnetostrictive ultrasonic transducer assembly which has relatively large openings for running the electrical coil lines without having the disadvantage of lowering the operating frequency. The new form of individual resonators (81) of the assembly provides for extreme miniaturisation of the transducers. The form specified relates to individual resonators which, in principle, have the form of an I section but have at one end a cube-shaped elongation (83) which prevents a sound radiation on this side. The form specified provides for wider openings between the individual resonators without reducing the resonant frequency so that coils (82) of sufficient thickness can still be run even with highly miniaturised transducers. <IMAGE>

Title: Composite bow with hollow arms
Inventor: JONES EUGENE R
IPC: F41B5/10
Filed: 1983-01-07
Abstract: The subject of the invention is a composite archery bow with hollow arms. The arms consist of a plurality of layers of fibre-reinforced material which are connected to one another and which form a fixed part of the arm, including the walls and the sides of the arms, and multiple hollow parts within the region defined by the walls and the sides. The hollow parts have elongate tapered rectangular cavities which extend from the thickened end of the arm to a point located approximately at 2/3 of the length of the arm. The fixed part of the arm is restricted to the portions of the arm which are necessary to withstand the compressive and bending forces and the moments of torsion generated when the bow is in operation. In particular, means are provided to strengthen the tips of the arms selectively, in order thereby to withstand distortion as a result of the offset winding cables. <IMAGE>

Title: Surgical clip suture apparatus for producing circular joins
Inventor: ZIEGLER HORST DR
IPC: A61B17/115
Filed: 1983-01-20
Abstract: A surgical clip suture apparatus for producing circular joins (anastomoses) has an elongate apparatus body through which there is a drilled hole and at one end of which there is an annular clip magazine which is arranged concentrically to the drilled hole. On the side of the clip magazine facing away from the apparatus body there is an annular counter-pressure plate for bending over the U-shaped clips; it is attached to the end of a tension bar which passes, secured against rotation, through the hole drilled in the apparatus body to an actuation member. According to the invention, the tension bar can be removed, in whole or in part, with the counter-pressure plate located thereon in the direction of the end of the apparatus body having the clip magazine. This makes it possible to produce circular joins even at places which are difficult to get at, e.g. above the diaphragm, without it being necessary to open the thoracic cavity, which is a considerable stress for the patient. <IMAGE>

Title: Process and apparatus for horizontal continuous casting of molten metals, especially of steel
Inventor: HENDERS SIEGFRIED DR ING
IPC: B22D11/045
Filed: 1983-01-21
Abstract: In such a process for horizontal continuous casting, the molten metal is conducted in a controlled manner, under the influence of gravity, from a supply container (2) into a cooled horizontal continuous casting mould (7), an electromagnetic force is exerted on said metal in the casting direction, and the solidified cast strand is continuously withdrawn. In order to avoid narrow and long supply channels for the casting metal, and to reduce the energy cost for the electromagnetic force so that there is the least possible risk of cavity formation in the upper cross-sectional region of the cast strand, it is proposed that the molten metal be let out downwards from the supply container (2) into the horizontal continuous casting mould (7) and there be deflected into the horizontal takeoff direction, and that the electromagnetic force be set so as to hold back the casting level (17) in a corresponding upper pouring opening (6) of the horizontal continuous casting mould (7), below the upper edge (10), on the entry side, of the adjoining horizontal casting channel (9). <IMAGE>

The increased load on the data path between processor and memory is absorbed by introducing a pipeline of memory blocks. The advantages of the computer proposed are: high throughput, high availability, ease of debugging, programmability in conventional languages and data-flow languages, very high input/output capacity, universal applicability (including real-time image processing and as a data base machine).
Patent DE-3321739-A1 (DE)
Title: Cyclic process in a steam engine for the purpose of increasing the thermal efficiency, in particular for steam power stations
IPC: F01K21/00
Filed: 1983-06-16
Abstract: According to the invention, a description is given of a cyclic process in a steam engine, in which process the condensation of the exhaust steam is achieved by virtue of the fact that the still pressurised exhaust steam emerging from the actual engine (e.g. the steam turbine or the reciprocating steam engine) is, on the one hand, passed in part via a throttling section while the remainder is passed via a further engine, the steam emerging from this engine, which has cooled further due to the performance of work, effects the condensation of the steam passed through the throttling section by absorbing the heat of condensation. The condensed and the uncondensed portion of the steam are pumped back separately into the cyclic process. The differential work from the two work processes (expansion work minus return pumping work) can be passed to the outside to perform useful work; it is equivalent to the heat fed in on the primary side. An improvement in thermal efficiency up to a theoretical figure of 100 % ( eta  = 1) is thereby possible. The higher outlay on machinery required for this purpose can be more or less offset by the elimination of the power station condenser and the cooling towers. The advantage over current steam power stations consists in the saving of approximately 50 % of primary energy with an equivalent reduction in environmental pollution by pollutants and waste heat and the same power output of the power station.
