Patent DE-2946774-A1 (DE)
Title: Refuse combustion system - with gases from pyrolysis chamber passed tangentially to final solids fusion chamber
Inventor: ALEXANDERSSON SVEN
IPC: B09B3/00
Filed: 1979-11-20
Abstract: A combustion plant, specially for refuse and waste products but also for coal, peat and other fossil fuels, has an enclosed first chamber in which a pyrolysis is maintained by the controlled admission of primary air. Gases enter a second chamber tangentially from the top of the first; clinker and fused remnants pass through a second channel at the bottom into the second chamber. The circulating gases complete the combustion of combustible parts and fuse the solids, if necessary with an addition of addition of extra heat. Air or oxygen is injected to decarburise the melt. This process combines the maximum utilisation of the heat with a reduction of the residua products (gases, entrained particles, ash, clinker) to the minimum and their conversion to a non-toxic material.

Title: Electronic thermostat with programmable memory - compares ambient temp. with desired temp. signals to generate output control signal
Inventor: LEVINE MICHAEL R
IPC: G05D23/20
Filed: 1979-12-19
Abstract: The thermostat for generating control signals for a furnace, air conditioner, or the like, employs a constant frequency, periodically alternating electrical source and an oscillator incorporating an element having a thermal-sensitive electrical characteristic so the oscillator frequency varies as a function of the ambient temeprature. A comparator receives the two outputs and generates a signal representative of the ambient temperature. The stable output is also provided to dividing circuits to generate a signal representative of the time that is used to interrogate a digital memory storing a desired temeprature-time program for the thermostat for a repetitive period, such as a week or month. The ambient temperature signal is compared with the desired temperature signal to generate an output control signal. A display provides a readout of time and temperature and is used along with a keyboard or the like in programming the memory.

Triggered by the action of one of the indicators, the compressed air closes the supply pipe, the engine thereby being stopped and protected from prolonged overloading. <IMAGE>
Patent DE-3205737-A1 (DE)
Inventor: BUCK ROBERT
IPC: G08B29/00
Filed: 1982-02-18
Abstract: A contactless motion detector, specifically an oscillator whose signal amplitude is attenuated or enhanced by the approach of a monitored metallic element, is periodically switched for brief periods into its alternate state by a train of short test pulses giving rise to corresponding checking pulses that are superimposed upon the integrated output voltage of the oscillator whereby that voltage is intermittently increased when at low level and/or intermittently reduced when at high level. These checking pulses, whether of the voltage-increasing or the voltage-reducing kind, are integrated to provide an enabling signal allowing a controlled load to be energized or de-energized according to the mean value of the output voltage; an absence of the enabling signal indicates a malfunction.
Patent DE-3207089-A1 (DE)
Title: Pressure swing adsorption process
Inventor: WILSON PETER HANCOCK
IPC: B01D53/047
Filed: 1982-02-26
Abstract: A pressure swing adsorption process is described, in which a gas mixture which contains a readily adsorbable gas component to be recovered and a less readily adsorbable gas component is introduced at low pressure into an adsorption zone, the pressure being increased before the less readily adsorbable gas component is flushed from the adsorption zone at high pressure. In a subsequent pressure reduction, the readily adsorbable gas component is obtained with an improved degree of purity. If a plurality of adsorption zones are employed, each zone in turn passes through the low-pressure adsorption, the increase in pressure, the high-pressure elution and the pressure reduction, pressure equalisation phases being preferably provided between the zones which must be pressurised subsequent to the adsorption and the pressure of which must be reduced subsequent to the elution. The process is suitable, inter alia, for producing nitrogen of improved purity from air and for producing highly pure methane from mixtures of methane and nitrogen. <IMAGE>
