Patent DE-2734872-A1 (DE)
Title: Short circuiting switch making earth connection - uses explosive charge to move contacts and employs hollow earth electrode
Inventor: BRUECKNER PAUL PROF DR ING DR
IPC: H01H39/00
Filed: 1977-08-03
Abstract: The switch is primarily intended for metal encapsulated gas insulated HV systems where it is used to earth a faulty section. The earth electrode is connected to the metal ducting (1) and terminates near an HV electrode (5). The earth electrode is hollow, filled with an amount of explosive (3), and connected to a firing circuit (4). The free end of the earth electrode is typically slotted (6) to give a series of fingers. When the charge (3) is fired the resulting explosion throws the free ends of the fingers against the HV electrode which is thus earther.

Title: Reaction turbine for low pressure fluid - has radial passages with tangential discharge in disc mounted on hollow shaft for fluid inlet
Inventor: MANIER WERNER
IPC: F01D1/32
Filed: 1977-08-30
Abstract: A disc (1) is mounted on a hollow shaft (3). Two or more radial passages (2) within the disc have internal openings which communicate with the bore of the hollow shaft. At the periphery of the disc these passages have openings (5) which are tangential to the disc.

Title: Gain controlled HF input circuit - has broadband FET amplifier stage to generate control voltage without feedback effects
Inventor: BRINKHAUS STEFAN
IPC: H03G1/04
Filed: 1977-09-02
Abstract: The gain controlled high frequency input circuit is designed to minimise signal distortion effects. The input signal is processed over a control stage preceding a high frequency amplifier. A broad band amplifier without feedback supplies a signal to a rectifier. The rectified signal is passed through a low pass filter and into a d.c. control voltage amplifier. This in turn controls the main control stage. The broad band amplifier employs an FEt to generate a control voltage without loading effects on the h.f. amplifier. The FET may be dual-gate type.

Title: Storage of heat for subsequent use - using reversible chemical reaction with greatly reduced ambient losses
Inventor: HAENNI HERMANN DIPL PHYS DR
IPC: F28D20/00
Filed: 1978-02-28
Abstract: The periodic storage and discharge of heat uses at least one heat transformer contg. a working medium. This undergoes an endothermic reversible reaction to give a solid and a gaseous component. In the storage phase, heat is added to the absorber/releaser and the medium yields the gaseous component, which flows into the condenser/evaporator section. Here it condenses releasing heat. In a heat release mode, the condensate in the condenser/evaporator section is evaporated. This then releases heat in the absorber/release zone by reacting with the solid phase which absorbs it. Solar or electric energy can be used as sources of heat. The energy released by condensation is released to atmosphere or to a latent heat store. The heat released during the release mode is used for water heating or space heating. For use in storing solar energy or electrical energy during the night.

Patent DE-2834751-A1 (DE)
IPC: G10L19/00
Filed: 1978-08-08
Abstract: In a voice coding system each vowel or consonant sound, or phoneme, is divided into repeated similar sections and the analog electrical equivalent of one of those sections is transmitted. If repetitive sections cannot be distinguished, e.g. during unvoiced consonants, a signal is derived from a section of predetermined length. The signal is transmitted in digital form together with signals indicating the number of sections in the phoneme, the intensity of the phoneme, the intensity of each of the repeated sections of the phoneme, any pre-equalisation applied to the speech, and phoneme change. On reception the analog electric equivalent signal is recovered, stored, level controlled, equalised, and repeated the appropriate number of times until a phoneme change is indicated.
