Patent DE-3909500-A1 (DE)
Title: Foil solar collector, in particular a holder
Inventor: GRAEF WALTER
IPC: F24J2/52
Filed: 1989-03-22
Abstract: The described design of the solar collector permits the use of foils as an optically transparent cover, and of polypropylene plates as absorbers. The foils are clamped in the frame groove of the collector by means of soft rubber piping with a hard core. Thermal expansions of the foil are compensated by the rubber piping, which serves as a resilient element, and keep the foil tensioned in the hot operating state and prevent the foil from overexpanding upon cooling. Also conceivable instead of the rubber piping is a rubber hose filled with gas, which fulfils the same function as a temperature-dependent resilient element. The polypropylene absorber is mounted in such a way that thermal expansions are possible in the longitudinal and transverse directions without substantial deformation of the plate. The essential advantage of the use of foil covers combined with polypropylene absorbers in solar collectors are low weight and low material costs.

Title: Method and circuit arrangement for generating an auxiliary signal
Inventor: RUECKERT HOLGER DIPL ING
IPC: H04N5/95
Filed: 1989-03-25
Abstract: In the case of a method for generating an auxiliary signal which consists of reference oscillations and a synchronous pulse and is for detecting timing errors in the case of reproduction of video signals to be recorded on magnetic tape, the amplitude profile of the auxiliary signal is stored in programmable read-only memory (PROM) (9, 10) in the form of data words. The programmable read-only memory (9, 10) is read out using an address signal coupled to the horizontal-frequency synchronous signal of the video signal. The data of the amplitude profile for the reference oscillations and the data for the amplitude profile of the synchronous pulse are fed on different conducting paths to a common D/A converter (14), in order not to reduce the dynamic range of a digital video signal fixed by a given bit width. <IMAGE>

Title: Rechargeable batteries charging process - determining end of initial charge phase by detecting pressure in cell
Inventor: POESCH GERD DR ING
IPC: H01M10/44
Filed: 1989-11-16
Abstract: A charging process for use with rechargable batteries is carried out in several phases in which transistors occur to avoid the continuous generation of gas. The initial charging phase is cycled dependent upon the input of a pressure sensor that detects the increase in internal cell pressure when gas is generated. This provides an optimum initial period for the charge phase. A valve may be used to allow gas escape from the cell at the end of the phase. Switchover takes place at the next phase which occurs at an increased voltage, which is held at a constant value. ADVANTAGE - Provides optimum changeover between  charging phases of battery.
