Title: Device for controlling an induction machine
Inventor: YANASE TAKAO DIPL ING

Patent DE-3145808-A1 (DE)
Title: Process for blow-moulding or injection-moulding a plastic article
IPC: B29C49/24
Filed: 1981-11-19
Abstract: The invention relates to a process for blow-moulding or injection-moulding a plastic article, in which a material in web form is laid in an opened hollow mould and is pressed by the polymer melt in the closed hollow mould by blowing or injecting against the inside wall of the hollow mould, forming a composite article. The material in web form is equipped with a textile layer on the surface side, facing the plastic, so that the polymer melt penetrates into the hollow or intermediate spaces of the textile layer and forms a positive, firmly adhering surface bond between the plastic article and the material in sheet form. Since the adhesive bonding operation required for laminating is dispensed with, the novel process permits an inexpensive, energy-saving and environmentally friendly production of a coated plastic article.

Title: Process and apparatus for the recoilless opening of a toroidal outer elastomer sheathing in tyre production
Inventor: MARTIN FRIEDRICH
IPC: B29D30/06
Filed: 1981-12-17
Abstract: Process and apparatus for the recoilless opening of a toroidal outer elastomer sheathing in tyre production, into which a green- cover is introduced before vulcanising. The tensioning members, effecting the opening of the sheath, are arranged peripherally on a base body and engage behind an inner rim of the sheath, being able to carry out both an outwardly directed opening movement and a vertical swivelling movement until there is complete, flush termination with the workplate. The tensioning members are designed, mounted and driven in such a way that it is not possible for the tensioning members to recoil if the sheath tears. For this purpose, the tensioning members may either comprise lowerable cabanes, from which essentially horizontally driven, relaxed tensioning bands emerge or the tensioning members have a semicircular rigid form which is positively guided and driven.

Patent DE-3200822-A1 (DE)
Title: Method for coupling proteins and haptens to Teflon< TM > for immunological and enzymatic determinations
Inventor: KLITZING LEBRECHT VON DR
IPC: C12N11/08
Filed: 1982-01-14
Abstract: In immunological determinations, antigens in the test mixture react with antibodies to give a complex which must be separated off from the free antigen or antibody for the quantification. This normally takes place by centrifugation, either immediately or after further reactions which are aimed to increase the mass of the complexes. The invention described herein is characterised in that antibodies (or antigens) are bonded to chemically inert plastic which is then removed from the reaction mixture mechanically. The adsorptive binding to polystyrenes as hitherto is non-specific and therefore unsuitable. A specific covalent bonding is achieved after activation of TEFLON< TM > with Na and NH3, wherein the free amino groups react via a carbodiimide bridge with the antibodies (or antigens). These treated TEFLON< TM > discs can then remove the free antigens (or antibodies) from the mixture. In a radioimmunological determination (RIA) for example the radioactivity on this reacted TEFLON< TM > disc is subsequently measured. In place of antibodies or antigens, it is possible to couple enzymes to activated TEFLON< TM > discs which can then be specifically added to a reaction mixture and removed again too. This method has the crucial advantage compared with the current method of thermal denaturation that heat-sensitive metabolites are not decomposed.

Patent DE-3204288-A1 (DE)
Title: Sorption heat pump
Inventor: KANTNER ALEXANDER DR ING
IPC: F25B30/04
Filed: 1982-02-06
Abstract: The present invention relates to a sorption heat pump, in particular absorption heat pump, which has an expeller, condenser, absorber and evaporator, a consumer being heated by heat extraction in the condenser and absorber. In a parallel connection of the consumer branches to the absorber and the condenser, it must be ensured that the throughput distribution does not take place in a random manner but is controlled as a function of the outside temperature, in order that the temperature level both in the condenser and in the absorber can be kept at the optimum values for condensation and absorption without on the other hand influencing the heat supply to the consumer. The throughput distribution can take place by a three-way valve which is governed by a motor and which is arranged on the return side of the consumer together with a circulating pump if the consumer consists of a central heating system. The main area of application of the invention is heating installations.

Patent DE-3207430-A1 (DE)
Title: Balance of very flat design
Inventor: PUETTER PAUL STEFAN DIPL PHYS
IPC: G01G21/24
Filed: 1982-03-02
Abstract: The very flat design of the balance is achieved by means of a parallel guide having horizontal levers. However, horizontal frictional forces can, at the same time, occur at points of contact and, under some circumstances, can falsify the weighing result. The invention minimises the horizontal forces by making some or all of the connections by means of connecting pieces which are mounted rotatably and with low friction or are flexible. The invention can be used for any parallel guide having horizontal levers.

Title: Hydrostatic drive for longitudinal conveyors
Inventor: GOELZ ROLF
IPC: F16H61/42
Filed: 1982-03-18
Abstract: The hydrostatic drive according to the invention for longitudinal conveyors is intended to improve the drives, known per se, of this type for machines or operating means - for example so-called shuttle drives - which automatically carry out backwards and forwards movements with respect to the simplicity of their design, increased operational reliability and above all the exact observance of a desired displacement/speed profile. For this purpose, the drive is provided with a control device in which the output side of a reduction gear arranged downstream of the hydrostatic gear drives a control cam, in a mechanically operated manner, in proportion to the revolutions of the output side of the gear. The control cam has separate radial cams, which are connected to it so as to be easily interchangeable, for the forwards and backwards movement of the drive, the shape of said cams ensuring, by virtue of a guide roller arranged on the adjustment linkage for the primary (pump) part of the hydrostatic gear, the exact observance of the displacement/speed profile which can be determined by the control cams between the stationary state in the two end positions of the control cam and the expected maximum speeds in the two directions of movement of the drive.
