Abstract: @ Disclosed is a level detector in a differential amplifier circuit (21) in an amplitude-limiting amplifying system for angle-modulation signal amplification. The differential amplifier circuit (21) is made up of differentially paired transistors (Q1, Q2). The level detector (24) contains first and second transistors (Q7, Q8) which form a differential pair. In the first transistor (Q7), the base is connected to an interjunction of the emitters of the differentially paired transistors (Q1, Q2). A second transistor (Q8) is connected at the emitter to the emitter of the first transistor (07). A current source (13) is connected to the emitter interjunction of the first and second transistors (Q7, Q8). A bias circuit (25) applies a predetermined bias potential to the base of the second transistor (Q8). An output signal containing the detected level information of the input signal is derived from the collector of the first or second transistor (Q7, Q8).

Abstract: Verfahren und Vorrichtungen zur Einstellung des PID-Verhaltens von Reglerkompensationsnetzwerken, insbesondere bei Hydropulsmaschinen, sollen auch bei komplizierten Prüfkörpern in optimaler Weise durchführbar sein, ohne daß die Gefahr besteht, den Prüfkörper zu zerstören und ohne daß langwierige Einstellarbeiten erforderlich sind, wobei nach einer genauen Vorschrift vorgegangen werden kann. Dies wird hier dadurch erreicht, daß bei geschlossenem Regelkreis dessen Stabilitätsortskurve bestimmt wird, die eine Transformierte der sog. Nyquist-Ortskurve darstellt und dann das Reglerkompensationsnetzwerk so lange verstellt wird, bis die Stabilitätsortskurve einen gewünschten Verlauf aufweist.

Abstract: This invention relates to processes which are used to produce, isolate, and characterize human rotavirus/animal rotavirus reassortants and to produce live attenuated vaccines and vaccine precursors. In the present strategy there is involved the new use of either (1) high titer hyperimmune antisera or (2) monoclonal antisera to select reassortants with the desired human phenotype. A point of novelty is the finding that antiserum or monoclonal antisera alone, so long as it possesses high titer neutralizing activity against only the 34-38Kd glycoprotein or of the animal parent, is sufficient to use for selection of reassortant rotaviruses with human phenotype. Also, the novel products are live attenuated vaccine precursors and vaccines.

Abstract: The present invention relates to a layered water sealing article of manufacture including a layer of a flexible sheet material adhered to a layer of a composition comprising a non-hydrated water-swellable clay intimately contacted with a polypropene, polybutene, or mixtures thereof particularly useful as a water barrier. The water swellable clay composition can be adhered to the flexible sheet material in any manner, such as by extruding the composition in sheet form onto a layer of sheet material. The clay composition layer is sufficiently tacky to adhere to the sheet material on one major surface, and is sufficiently tacky for adherence to a wall or conduit, floor or roof on an exposed major surface in areas of potential water flow to prevent the seepage of water through the bentonite clay composition layer. In the embodiment, the clay composition layer includes a polypropene and/or a polybutene and an elastomer, such as butyl rubber, having sufficient resilience to stretch or expand with the expanding water-swellable clay composition upon hydration and to aid in maintaining the structural integrity and cohesiveness of the clay composition. In another embodiment, the clay composition layer comprises a water-swellable clay, an elastomer, and any plasticizer compatible with the elastomer.

The equipment comprises first distance sensors (G 1 -G 5 ) which are mounted in fixed and known positions in relation to the robot. Each first sensor measures the distance between the sensor and the object and supplies a signal, corresponding to this distance, to a calculating unit (6) which, on the basis of the sensor signals, makes a first, rough determination of the position and orientation of the object In the necessary number of degrees of freedom. Control means are arranged to guide the robot, on the basis of the position of the object thus determined, to predetermined positions (e.g. P 1 ) in relation to the object. In each one of these positions, an accurate position determination, preferably in two degrees of freedom, of a small area of the object is made with the aid of a sensor (G 6 ) mounted on the robot tool. Based on these position determinations, a second, accurate position determination in relation to the robot is made of a part of the object which is relevant to the work operation to be performed.
