Title: Automatically controlled drum washing machine
Inventor: GRAF RICHARD DIPL ING
IPC: D06F39/04
Filed: 1988-02-24
Abstract: In drum washing machines which work with an extremely low water level and which have special arrangements for wetting the washing during a wetting phase, it is only at a late stage that a lye level is reached which initiates further process stages for washing. The result is a great time delay for the beginning of the washing process. Moreover, the wetting effect is poor with cold lye and leads to a long wetting phase. The invention consists in shifting the beginning of lye heating forwards and to this end makes use of a switching arrangement which also has a level switching point, at which the lye already completely covers the heating arrangement. The switching measure for switching on the heating arrangement is triggered immediately after reaching this level switching point. <IMAGE>

Patent DE-3825422-A1 (DE)
Title: Device for measuring the density of fluids by means of acoustic signals
Inventor: BECKER WOLF JUERGEN PROF DIPL
IPC: G01N29/024
Filed: 1988-07-27
Abstract: The measurement of the density of fluids (gases and liquids) is carried out by means of detecting the transit time of an acoustic signal through an acoustic measuring path filled with fluid and converting it into the density. The transit time of the acoustic signal is measured by means of generating a series frequency, in that an acoustic signal on an electroacoustic receiving transducer having an electronic device triggers an acoustic signal to an electroacoustic transmitting transducer for transmitting through the acoustic measuring path. This can be carried out both with acoustic pulse signals and with acoustic continuous signals. In the latter case, the electroacoustic transmitting transducer, the acoustic measuring path and the electroacoustic receiving transducer are in the feedback network of an electronic broadband amplifier and thus in total form a self-exciting electroacoustic oscillator. In a further refinement, the electronic amplifier can be formed by a phase-locked loop (PLL), consisting of a phase detector, a low-pass filter and a voltage-controlled oscillator (VCO), the electroacoustic feedback network in this case forming the external feedback of the PLL. Having electronic dividers in the internal and external feedback of the PLL, the VCO works at a multiple of the series frequency, so that the frequency of the acoustic signal can be matched optimally to the electroacoustic properties of the transducers.

Patent DE-3832393-A1 (DE)
Title: Method of keeping the geometry of an extrudate constant
Inventor: LIMPER ANDREAS DR
IPC: B29C48/92
Filed: 1988-09-23
Abstract: In the case of an extruder for extruding profiles with a control loop for the mass throughput, it has been found that changes in mass throughput are detected too slowly and that, as a result, countermeasures in response to changes in mass throughput cannot be initiated in time. In order to overcome these disadvantages, it is proposed to provide the mass throughput control with a secondary control for constant melt pressure upstream of the extruder die. As a result, profiles of an optimum weight per metre and optimum geometry can be achieved.

Patent DE-3837165-A1 (DE)
Title: Heating system
IPC: F02G5/02
Filed: 1988-11-02
Abstract: Heating system consisting of a heat exchanger, an external-combustion heat engine, a compressor heat pump and a heat plant. The compressor and the expansion engine of the compressor heat pump are coupled to an external-combustion heat engine. The waste gases obtained by combustion supply the external-combustion heat engine with heat and then flow through a part of the heat exchanger. The external-combustion heat engine has a cooler fitted in the heat exchanger and drives the compressor. The waste gases driving the external-combustion heat engine, after flowing through the first part of the heat exchanger, pass into the compressor, are compressed there and then flow through the second part of the heat exchanger, releasing their heat. After flowing through the latter, they pass into the expansion engine and drive the latter. The expansion engine for its part drives, along with the external-combustion heat engine, the compressor. By virtue of this design, not only the heat obtained during combustion is utilised, but also the temperature difference between the heated medium and the combustion temperature.
