Title: Condensation pressure fluctuation prevention method - mixes non-condensing gas with vapour to be condensed in liquid
Inventor: SCHMITZ GERD DIPL PHYS
IPC: F28B3/06
Filed: 1979-08-29
Abstract: The method avoids sudden variations in pressure when condensing a vapour by directing it into a liquid. A non-condensing gas is mixed with the vapour to be condensed, the latter being typically passed through an ejector nozzle to draw the gas in, the latter being delivered via a non-return valve. On condensation, a small residual volume of compressible gas remains inside each vapour bubble in the liquid, acting as a spring to absorb movement of the liquid masses, and thus absorbing shock loads.

Title: Circuit breaker blowout system - is for improved short circuit capability extending one terminal under cooling plates to improve deionisation
Inventor: GERHARDT KARL ING GRAD
IPC: H01H9/34
Filed: 1980-05-02
Abstract: The application is principally to circuit breakers for protection of wiring. The fixed contact (24) of the switch is extended beyond the normally provided arcing section (26) into a conductor (32,33) which extends some distance below the arc cooling plates (38). The arcing contact and arc cooling plate (40) furthest from the fixed terminal (24) is also extended (44) so that both extensions (33,44) for a duct which opens into the gas discharge channel (42). By extending the live terminal below the cooling plates (38) ionised particles from the arc are attracted to it. The space in the arcing region is thus rapidly deionised and the risk of the arc restriking in the next voltage cycle greatly diminished. By suitable configuration of the extensions (33,44), the arc can be sustained at their narrowest spacing and any tendency to restrike across the contacts effectively suppressed.

Patent DE-3021690-A1 (DE)
Title: Audio amplifier with gain controlled by ambient noise level - uses digital filtering system to measure and store ambient noise conditions
IPC: H03G3/32
Filed: 1980-06-10
Abstract: The amplifier is for audio systems which have to operate under conditions of high ambient noise, e.g. public address systems and audio equipment in vehicles or aircraft. The audio output level is automatically regulated according to ambient noise level to maintain a desired difference in volume. A microphone detects the ambient noise. Its output is applied to a band-pass filter which blocks all frequencies except those suppressed by a band block filter in the audio system input. The resulting signal is applied, after amplification, to a sample hold circuit. The latter passes a signal to the variable gain stage of the audio amplifier to adjust the output to the desired volume. The hold circuit is reset by a timer which also controls the cyclic application of the band block filter in the input to the audio amplifier. The actual value of the stored sample of background noise is thus continually updated. Below a background limit the timer and hold circuits are inactive. The use of digital circuit makes the proposed system practical.
