Inventor: MARTIN JOHANNES JOSEF
IPC: F23C99/00
Filed: 1980-07-08
Abstract: A combustion apparatus has a combustion chamber which is divided into combustion zones respectively communicating with individual mixing zones in a mixing chamber. Combustion air enters the mixing zones and then flows into the combustion zones. The concentration of NOx in the combustion products of each of the combustion zones is measured and water vapor is fed into each mixing zone in an amount which depends upon the NOx concentration for the corresponding combustion zone. The amount of water vapor fed into a mixing zone is such as to maintain the combustion temperature below a value at which substantial quantities of NOx are formed. The water vapor is fed into the mixing zones generally countercurrent to the combustion air entering the combustion zones and the water vapor and combustion air flow into the combustion zones together.

Patent DE-3100121-A1 (DE)
Title: Process and apparatus for heating a double-walled service-water storage tank by means of a heat pump
IPC: F24D19/10
Filed: 1981-01-05
Abstract: A double-walled service-water storage tank has a service-water compartment (12) and a heating-water compartment (11). A heating of the heating water takes place by means of a heat pump connected to the heating-water compartment (11). The heat pump is switched off or isolated from the heating-water circuit by a safety circuit at a predetermined maximum safety temperature. So that a switching-on and switching-off of the heat pump (13) can be carried out according to an optimum time cycle, the heat pump (13) is switched off or isolated from the heating-water circuit as early as at a highest temperature which is slightly below the maximum temperature. Only then is the heat pump (13) switched on again or connected to the heating-water circuit. This is continued until substantial temperature equalisation has taken place between the service-water compartment (11) and the heating-water compartment (12). <IMAGE>

Patent DE-3102285-A1 (DE)
Title: Testing of foamed insulations by infrared techniques
Inventor: WELLE REINHARD G DIPL ING
IPC: G01N25/72
Filed: 1981-01-24
Abstract: The patent claim addresses mainly the field of foamed materials. Infrared techniques makes it possible to detect weak points, (insulation), specific constructional aspects (flow of heat and cold) or any cavities (piping) occurring during foaming. A cold/heat zone between the object to be tested and the infrared camera makes it possible to analyse the infrared recording. The abovementioned factors are detected and it is thus possible to take appropriate measures. For example, it had hitherto not been possible, in building containers, to localise cavities (piping) accurately. All other test methods are eliminated on cost or physical grounds (X-ray, ultrasound etc.). This test method thus makes it possible to achieve improvements in quality or avoid high resulting costs.
