Title: Capacitor discharge electronic single-phase electricity meter - has stabilised direct voltage supply providing reference voltage for calibration
Inventor: SEIBT ARTUR DR ING
IPC: G01R21/127
Filed: 1979-09-28
Abstract: An electronic single-phase electricity meter operating on the capacitor discharge principle has a time division multiplexer multiplying the load voltage and a signal proportional to the current. The integrated current signal is compared with two limit values and a pulsed signal derived whose pulse frequency is proportional to power. Its circuitry is simplified compared to conventional arrangements so as to make it more economical and compact. Its direct voltage supply source has a precision voltage regulator in one or both branches. The stabilised direct voltage output acts as a reference voltage for all the calibration defining circuit elements. An operational amplifier comparator circuit is used. This drives an EXCLUSIVE-OR gate via a diode. The other gate input is connected to the reference potential and its output to the comparator positive input.

Patent DE-3112791-A1 (DE)
Title: Method for controlling cutting on electronic yarn cleaners
Inventor: WULFF GUNTHER DIPL PHYS
IPC: B65H63/06
Filed: 1981-03-31
Abstract: Electronic yarn cleaners must be capable of monitoring a large range of different yarn diameters and of cutting through. The electromagnetically actuated cutting devices of the yarn cleaners therefore always have a capacity rated for the thickest yarn of their measuring range. The capacity of the cutting device, which is then overrated where thin yarns are concerned, leads to unnecessarily rapid wear and damage to the cutting elements. This is prevented, according to the invention, in that the capacity of the cutting device is adjusted automatically in proportion to the diameter of the yarn monitored by the yarn cleaner and a substantially longer lifetime of the cutting device is thereby achieved.

Patent DE-3131642-A1 (DE)
Title: Heat exchanger for viscous and pasty media, in particular mashes
Inventor: SCHNECK EMIL
IPC: C12C7/06
Filed: 1981-08-11
Abstract: Heat exchangers are essentially composed of piping systems spirally nested in each other, through which flows a cooling medium. The medium to be cooled is pumped through cavities lying between the piping systems. The media strand formed in this case is therefore relatively intensely cooled only at the outer layers by heat exchange with the piping systems, while the interior of the media strand is only insignificantly cooled, since a direct heat exchange with the piping systems does not take place. To increase the degree of cooling action, according to the invention the heat exchanger is formed from a multiplicity of box-shaped chambers lying one above the other with shared intermediate bases and one vertical partition each, the chambers having reversing channels at the end to connect to the next chamber but one in each case. The medium to be cooled is thus continuously intensely deformed on flowing through the heat exchanger, so that no temperature gradient within the media strand can result. The heat exchanger according to the invention operates with a high efficiency without use of stirrers, which must be driven, with favourable structural dimensions and simple construction. <IMAGE>
