Title: Method and apparatus for prestressing long tendons
Inventor: SCHERRER FRIEDHELM
IPC: E04G21/12
Filed: 1982-05-05
Abstract: Method for prestressing the prestressing steel members of long tendons using a prestressing apparatus comprising a hollow-piston prestressing jack having an outer cylinder shell and an inner cylinder shell, a jack seat, an anchor plate arranged on the structure and a prestressing plate mounted on the hollow-piston prestressing jack. After a first extension of the hollow piston, the inner cylinder shell of the hollow-piston prestressing jack is supported on the anchor plate with the aid of a lengthening member and the hollow piston is retracted again. Subsequently, an intermediate ring is arranged between press seat and hollow piston, this ring raising the press seat. The hollow piston is then extended again. During the first extension, during the retraction and during the second extension of the hollow piston, the prestressing steel members remain wedged in the prestressing plate. The wedging of the prestressing steel members in the anchor plate is effected only after this. A time-consuming intermediate wedging is unnecessary even with extremely long drawing-out paths for the prestressing steel members. <IMAGE>

Title: Heating device
Inventor: FRICKE HANS-JUERGEN DR ING
IPC: F01P3/20
Filed: 1982-08-27
Abstract: The device for heating the passenger compartment or coolant circuit of a vehicle has a high-pressure expulsion pump (12) which is driven by the internal combustion engine (10). The pump feeds operating medium out of a container (13) to a pressure limiting valve in which the operating medium is heated up by throttling and the heat generated in this way is conducted away in a heat exchanger (17), for example into the coolant circuit or the passenger compartment. A magnet coupling (11) which can be switched as a function of temperature and/or engine speed is located between pump and internal combustion engine. If, for example, the desired temperature in the passenger compartment is reached, the high-pressure expulsion pump (12) is separated from the internal combustion engine by the coupling. In this way, a simple, energy-saving and very effective supplementary vehicle heating system is obtained.

Title: Arrangement for extending the frequency range of transmitters and receivers
Inventor: MANKOPF MICHAEL DR ING
IPC: H03J5/24
Filed: 1983-03-02
Abstract: Arrangement for extending the frequency range of transmitters and receivers. In transmitting and receiving systems whose frequency range is extended by means of frequency converters, changeover devices are required in order to route the signal path as required either directly or via a frequency converter. In order to avoid the disadvantages of changeover devices of this type, the signal path is routed according to the invention entirely via one frequency converter and the circuitry of the latter is designed in such a way that the transmission or reception signals are either through-connected in unmodified form or are mixed with the frequency of an auxiliary oscillator as required. <IMAGE>

Patent DE-3314784-A1 (DE)
Title: Circuit arrangement for movement detection
Inventor: WERTENAUER HELMUT
IPC: G01S13/56
Filed: 1983-04-23
Abstract: A circuit arrangement for movement detection, particularly for urinals and other sanitary fittings, is described in which the spatial resolution capability of the (generally digital) evaluating circuit is increased by the fact that the output signal of a microwave module first passes through a frequency multiplier circuit before it is output to the evaluating circuit. In this manner, the number of zero crossings which can be detected and processed by the evaluating circuit is correspondingly multiplied without increasing the operating frequency of the microwave module.

Patent DE-3319665-A1 (DE)
Title: Linear movement device, especially for spray elements
Inventor: HESTERMANN GERHARD
IPC: B05B13/04
Filed: 1983-05-31
Abstract: The device has a counterweight which is connected by an upper and a lower roller, and also by a belt or chain, to the main slide carrying the spray elements, the drive being taken over by one of these. Because of the centrifugal mass, which is doubled by the counterweight, a respective spring element is present for each reversal of movement, which is set, together with the end switch element effecting the changeover of the direction of movement, at the desired reversal point in each case. The spring element is compressed by the inertial forces, brakes the two partial mass slides including the spray element and counterweight, and accelerates them in the opposite direction. Since the direction of movement of the drive motor is changed over approximately simultaneously by the end switch elements in a different manner, the drive does not need to be designed for lifting a slide loaded with spray elements or for the braking and acceleration of the masses, but only for the small frictional forces. Furthermore, the invention extends to an especially favourable solution as regards the arrangement of the guide rails.
