Patent DE-3628214-A1 (DE)
Title: Heat engine
Inventor: FETZER ROMAN
IPC: F02G1/043
Filed: 1986-08-20
Abstract: In order to convert thermal energy into mechanical energy, in the case of a heat engine having external heat input a differential piston is moved up and down in a cylinder between two accumulators by means of two open or closed thermodynamic cyclic processes of a gaseous working medium which run simultaneously but in opposite directions. This movement is converted by means of a scotch-yoke mechanism into a rotary movement for the purpose of tapping force. A control piston which varies the working pressure as a function of load in conjunction with the change in heat input is used to control the output. A high efficiency is achieved by means of heat exchange between the expanded working medium and the working medium to be compressed during the cyclic process and by utilising the residual energy of the expelled working medium and of the remaining exhaust gases from the heat input in a working turbine. When the heat engine is used as a vehicle drive, working medium which is excessively compressed, e.g. during sliding operation, can be collected in an additional accumulator and reused as required. It is possible in this case to achieve braking which is free from loss and wear. Complete freedom from exhaust gas and pollutants is yielded in conjunction with a closed cycle and the use of the suitable heat input.

Title: Top-loading washing machine
Inventor: ANKELMANN WOLFGANG DIPL ING
IPC: D06F33/40
Filed: 1988-06-25
Abstract: A dynamic-pressure measuring system for an electronic speed regulation of the drive motor has to be integrated in tubs made of plastic for abovementioned washing machines. The relation between the dynamic pressure occurring during spinning and the water or foam in the tub serves for regulating the spinning speed. This method has hitherto been applicable only in front-loading washing machines having special-steel tubs. A retaining chamber (2) with a flow-off connection (3) is formed at the lowest point of a plastic tub (1). A skirt (5) and connection piece (4) pointing rearwards at rightangles for a pressure-measuring device are located within the retaining chamber (2). During spinning, water/lye is forced into the retaining chamber (2), and the fluctuating dynamic pressure occurring at the connection piece (4) is converted into signals via pressure sensors and fed to an electronic speed-regulating circuit. The top-loading washing machine is suitable mainly for households with confined conditions of space. <IMAGE>
