Abstract: Process for making metal oxide varistor precursor powder comprising (a) dissolving soluble precursors of the additive metal oxides, e.g. bismuth nitrate as precursor for bismuth oxide, in an aqueous solution, (b) forming a suspension or slurry in the aqueous solution of a powder of the desired primary metal oxide, e.g. zinc oxide, having the desired particle size, (c) adding a precipitating reagent to convert the additive metal from the soluble precursor form to the oxide or hydrous oxide form and precipitate the oxide or hydrous oxide in the presence of the primary metal oxide particles, (d) removing water and by-product salts to form a powder. The resulting varistor precursor powder contains smaller particles of the additive metal oxides evenly distributed throughout larger particles of the primary metal oxide. Varistors prepared from the resulting powder can be sintered at temperatures lower than conventionally used, for example 900 DEG C - 1000 DEG C and the resulting varistors exhibit properties of volts per grain boundary value higher than conventional varistors for example 3.75 to 4.5 and dielectric constants lower than conventional varistors, e.g., under 1000.

Abstract: For subsequent treatment of clarified juice, the juice is placed in contact with an additive, e.g. PVPP, and filtered in a cross-flow filtration device (11), whereby the heated juice is separated from the additive in the form of a permeate. The additive can be regenerated inside or outside the installation by adding water and alkaline solution. After regeneration, the alkaline solution is removed by diafiltration on the permeate side of the cross-flow filtration device (11). The cross-flow filtration permits the yield, the universal applicability of additives, and the quality of the treatment of the juice to be substantially improved.

Abstract: The (plasticised) melt rendered able to flow must be degassed on its way to the outlet. To make the degassing section pressureless, an upstream restrictor (4) is provided, through which the melt flows. The through-flow cross-sectional area of the at least one spiral of an extruder screw (1) is shut off and the restrictor (4) is provided with an adjustable through-flow cross-sectional area. The restrictor may comprise, in a simple way, two breaker plates (12, 13), which are turned about their longitudinal axis counter to each other in their plane. Each breaker plate has an invariable through-flow cross-sectional area. The holes (20, 21) of the two breaker plates (12, 13) coincide with one another more or less (A, C) or not at all (B). As a result, depending on the state or type of melt, the rate of throughput of the melt through the extrusion apparatus can be controlled independently of the speed of the extruder screw (1). To a greater extent than before, different melts can be conveyed by the same extruder screw (1). It is also possible to operate with a shorter extruder screw than hitherto. The breaker plates (12, 13) can be easily interchanged.

Abstract: A double interaction switch has a case in which a single block of contactors is controlled by two levers; namely, one monostable lever and one bistable lever. The bistable lever may be locked in one of its two stable positions. When the bistable lever is so locked, the monostable lever may be moved, and actuation of the bistable lever thereafter causes it to return to its unlocked position. When the monostable lever comes back to its rest position, with the bistable lever initially locked, the bistable lever comes back to its rest position. The bistable lever is lockable by means of a rod which may pivot under the action of a labyrinth, provided on the lever. The switch is suitable for use with "hands free" telephone receiver sets.

Abstract: A novel system for remote detection and imaging of underwater objects is presented. In accordance with the present invention, a laser is used to generate short pulses of light with pulse widths on the order of nanoseconds. The laser light is expanded by optics and projected down towards the surface of the water and to an object. Intensified CCD (charge coupled device) cameras (preferably two) are electronically shuttered after the time delay corresponding to the round trip propagation time and from to the object. This timing eliminates light scattered by the water from in front of and behind the object. As a result, the veiling luminance of the water is greatly attenuated and faint target signatures can be seen. The resulting gated images (displayed on a CRT) have sufficient spatial resolution to classify and/or identify the object. The imaging lidar system of the present invention takes advantage of the fact that all opaque targets will cast a shadow. The exposure of the two cameras in the system are timed such that one camera gives an image of the object against the backscattered light from the water while the other camera gives an image of the shadow of the object against the backscattered light. These two images are then subtracted to improve the detectability of the object.
