Title: Control circuit for solar heating system - has measured temp. supplied via similar input circuits to common preamplifier for obtaining identical amplification
Inventor: SCHWARZ KARL
IPC: G01K1/02
Filed: 1979-01-12
Abstract: The control circuit uses similar thermoelements to monitor related temperatures and temp. differences. The thermoelements are coupled via similar input circuits to a common preamplifier, one after the other in a periodic sequence. This allows each input value to be subjected to the same amplification during the interrogation period, with the system characteristics remaining constant during each interrogation period via a further identical input circuit. The output of the preamplifier may be coupled to an A/D converter, or to a sample and hold amplifier, with clock pulses controlling interrogation of each measured valued, obtained from the mains frequency. Each thermoelement may be coupled to the preamplifier via an identical filter, with zero adjustment of the preamplifier within each interrogation period via a further identical input circuit.

Patent DE-2919099-A1 (DE)
Title: Tightening torque limiting nut - has slots parallel to hexagon faces
Inventor: KOBUSCH KLAUS ING GRAD
IPC: F16B31/02
Filed: 1979-05-11
Abstract: A nut for a screwed joint is so designed that the spanner comes out of engagement with it when the tightening torque has reached a certain specified value. If the nut is made of metal, the deformation is permanent, if it is made of polyamide, it can be temporary and self-restoring. At least two of the opposite faces of the hexagon are fitted with a parallel slot which opens to one side of the periphery, and produces a cantilever in such a way that the mouth of the spanner causes the slot to be compressed. Further tightening of the nut is then impossible, but the nut can be loosened because the half of the hexagons which is active for unscrewing, has been left undisturbed. No special torque spanners are thus required; the same open-ended spanner can be used for tightening and unscrewing.
Patent DE-2933416-A1 (DE)
Title: Automatic intermediate frequency correction circuit for radio - determines maximum signal strength and uses it along with local frequency for digitally setting reception frequency
Inventor: KELLER HERBERT ING GRAD
IPC: H03J1/00
Filed: 1979-08-17
Abstract: The correction circuit corrects the denominator N of an oscillator's frequency (Fosc) by a value X and uses it as a digital value for the received frequency. The oscillator's frequency is compared in a phase locked loop with a reference frequency (Fref). The vco of the AM/FM tuner is used as local oscillator. The input range of the tuner is disabled during testing. The frequency range of the vco is changed in steps until the field strength of the IF signal is a max. This max. is stored along with the value of the IF local oscillator frequency and used to digitally set the frequency of the receiver.

Patent DE-3033014-A1 (DE)
Inventor: MAURER PAUL
IPC: F28D20/02
Filed: 1980-09-02
Abstract: The heat accumulator (10) comprises a tank (19) containing water-filled spherical receptacles made of an elastically extensible synthetic material. These receptacles are surrounded by a storage medium which contains an antifreeze agent and therefore has a lower freezing point than the water contained in the receptacles. If, therefore, the heat pump (11) is in operation, for example for heating the water contained in the water storage tank (17) for central heating, and the temperature in the accumulator drops below the zero point, no ice forms on the evaporator (13), so that its functioning is not impaired by ice formation. However, the water in the receptacles (21) freezes, so that the latent heat being released in the liquid/solid phase transition is utilised. <IMAGE>
