Patent DE-3120812-A1 (DE)
Inventor: SCHOENWALD SIEGFRIED
IPC: F04B27/06
Filed: 1981-05-25
Abstract: Improvements are disclosed in a radial piston compressor having pistons reciprocally disposed in the piston spaces of a cylinder block rotatably supported on a stationary shaft. The radial motion of the pistons is controlled by a rotatable guide which is arranged with its axis of rotation eccentrically to the axis of rotation of the cylinder block. The portion of the stationary shaft covered by the cylinder block includes a suction slot and a pressure slot extending along a portion of the circumference of the stationary shaft. Oil for sealing the cylinder block and the stationary shaft is introduced into the gap between the cylinder block and the stationary shaft. Due to the rotation of the cylinder block, the piston spaces are communicated alternatingly with the suction slot and the pressure slot through an opening provided in the bottom of the piston spaces. In order to obtain good sealing of the gap between the cylinder block and the stationary shaft by the oil contained in this gap, the gap is provided with a cross section which decreases from the suction slot toward the pressure slot, the oil being introduced into the gap in the vicinity of the largest gap cross section.

Title: Process for the preparation of 10,11-dihydro-5H-dibenzo- [a,d]cyclohepten-5-ones
Inventor: ZOCHE GUENTER DIPL CHEM DR
IPC: C07C49/755
Filed: 1981-10-31
Abstract: The present invention deals with a process for the preparation of 10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-one. The starting material of the process is o-carboxybibenzyl, or ring-substituted derivatives thereof, which is subjected to cyclocondensation. The cyclocondensation is carried out using di- and/or trichloromethylated aromatics in the presence of catalysts. Suitable catalysts are Lewis acids, preferably zinc salts and iron salts. The reaction is carried out at temperatures of between 50 and 150 DEG C. The course of the reaction can be monitored from the hydrogen chloride formed. After reaction is complete, the dibenzosuberone formed can be isolated direct in high purity by distillation without any further purification process. The byproducts formed in the reaction can also be recovered directly without any additional purification operations and are ready for further use.

Title: Heat accumulator, preferably for a hot water central heating system
Inventor: NIED PETER
IPC: F24D11/00
Filed: 1981-11-06
Abstract: Heat accumulator, preferably for a hot water central heating system. In the container (1) of the heat accumulator, there is arranged, in addition to an electric heating device (5), a combustion chamber for solid and/or liquid and/or gaseous fuels. If sufficient electrical energy is not available, heat can be generated in the combustion chamber by combustion of fuel. The accumulator container can also contain a heat exchanger (7) for supplying heat, e.g. solar heat. A heat exchanger (8) for heating service water can also be present. The arrangement of a combustion chamber (6) directly in the accumulator container has the advantage, in relation to a system with a separately installed heating boiler, that the installation of a system for mixed operation is considerably simplified. <IMAGE>

Title: Terminal strip for making electrical contact with a printed-circuit board having a multi-core cable, and a method for its production
Inventor: HUEBNER KLEMENS ING GRAD
IPC: H01R12/55
Filed: 1982-05-12
Abstract: A terminal strip for making electrical contact with a printed-circuit board having a multi-core cable, and a method for its production. It is proposed to construct the terminal strip as follows: a plastic base body consists of a bottom plate (1) and a back plate (2), which give the base body an L-shaped profile. Emerging from the back plate are metallic spring tongues (3) which, together with the two base body plates, form a cavity into which the printed-circuit board can be inserted. The spring tongues (3) are inclined with respect to the base plate, are forked at their ends and are in each case allocated to a cable passage opening (4) in the base body. The terminal strip is preferably an injection-moulded part with the spring tongues injection-moulded in; the base body in this case expediently consists of a thermoplastic, such as ABS (alkyl benzene sulphonate), and spring metal sheets on a bronze or beryllium base are primarily suitable as the spring tongue material. A terminal connector designed in this way is particularly cost-effective and allows a freely selectable allocation between the parts between which contact is to be made. It can be used primarily for the electrical connection of liquid-crystal displays to their drive units. <IMAGE>
