Inventor: BAKER DONAL EUGENE
IPC: G05F1/10
Filed: 1981-03-04
Abstract: A cycloconverter produces an AC output of a desired frequency from an AC power source, using a reference waveform and a novel feedback loop. The quality of the output waveform of the cycloconverter is greatly improved by the feedback loop which compensates for the inherent nonlinearity of the converter forward gain. A feedback signal, preferably proportional to the current through a shunt capacitor of a converter-output-filter, is multiplied by a compensating signal generated by full wave rectification of the cycloconverter AC reference signal with the resultant signal summed in opposition with the reference signal before it is applied to the converter control circuit. Alternatively a more precise compensating signal can be generated through 90° phase shifting and negative going full wave rectification of the sinusoidal cycloconverter reference signal.

Title: Apparatus for measuring blood pressure of laboratory animals.
Inventor: DANITZ BELA
IPC: A61B5/0225
Filed: 1980-12-23
Abstract: An apparatus for measuring blood pressure of laboratory animals e.g. rats, comprising respective cages (10) for accomodating the animals that have a bottom (11) which is preheated between 33 and 35` C to intensify circulation of the animals. Respective cuffs are arranged around the tails of the animals pressurized by a common pressure actuator (23). The cuffs comprise optical pulse sensors coupled to respective measuring channels of a measuring and filter unit (30) with steep low-pass characteristics having cut-off frequencies under 10 Hz to eliminate disturbing noise effects. The operation is controlled by an evaluating unit (40). In the method for measuring the blood pressure, the pressure is established and changed simultaneously for each animal located in preheated cages, and in each channel the pressure corresponding to the occurrence of the first sensed beat pulse is stored and regarded as a blood pressure value if an undisturbed pulsation is going on with predetermined conditions after the first beat. The measurements are carried out in a sequence of measuring periods and the corresponding results are evaluated by mathematical statistical technique for each animal. If the results cannot be evaluated, new measuring sequences are started.

Abstract: In this plant, an injection line (45) containing a flow resistance controller (49) whose control action has the effect that the coal part streams in the injection lines (45) are equal, leads to each blow-in site. To feed combustion air, the plant can be provided with a ring main (55) arranged around the process vessel and with blast connections (56) leading from the ring main to the individual blow-in sites, and each having one differential pressure transducer (58). When the differential pressure in the blast connection (56) falls below a preset value, the coal feed in the corresponding injection line (45) is interrupted until the burning site again permits the feed of hot air from the ring main. The plant can have a stock tank (15) and a metering bunker (24), each with a weighing device (65 and 74 respectively). The total coal mass flow to be introduced into the process vessel (44) is controlled without interruption by the weighing devices (65, 74). The stock tank (15) can be connected to a grinding unit (3) and to a preheating unit (2) upstream thereof. Warm flue gases or waste gases from other processes can be used for drying and conveying the coal.

Abstract: In the manufacture of non-returnable packages for milk and other beverages the laminated packing material is sealed to itself along linear sealing zones by causing outer thermoplastic layers of the packing material to fuse together. The strength of the seal obtained depends upon the thermoplastic surface being free of impurities, e.g. oxide coatings or residues of the contents of the package. In spite of the presence of impurities a strong seal can be obtained if the thermoplastic layers, within a limited region of the sealing zone, are pressed against each other with such a force that molten thermoplastic material is made to flow to adjoining regions (15), since in this case the thermoplastics are blended to such a degree that the seal-preventing layer of impurities is broken.
