Title: Synthetic filament prodn. - using high speed extrusion to create airflow in cooling chamber with increased vacuum below
Inventor: KOSCHINEK GUENTER
IPC: D01D5/092
Filed: 1992-07-15
Abstract: A process is claimed to spin and cool synthetic multifilament with a spinneret, having extruder head and a cooling chamber, with perforated walls. As the filament is drawn out, a suction develops in the chamber, and a reduced air pressure is arranged in the area below the cooling chamber. The appts. is also claimed. The extruder (1) forces the molten plastic material through as filament (2). A cylindrical, oval or square chamber, according to the shape of the spinneret, has perforated walls (3), which is designed to create an airflow to cool the filament, and this is drawn at a high speed. Suction is created from the room (5) as the filament (2) passes through the gap (4) at the bottom of the cooling chamber, and into the space (6) below. The suction is monitored and controlled (7), so that the space (6) is at a higher degree of vacuum than created by the airflow from the area (5). The filament may then be treated with a prepn., and is wound at a creel. ADVANTAGE - The pneumatic energy requirements are minimal, and the rate of filament prodn. is increased. The filament produced is very regular, and does not adhere.

Title: Quantitative movement analysis of fish - removing moving objects from video image to leave background, comparing successive images with background and recognising object by difference in intensity
Inventor: SPIESER HUNRICH DR
IPC: G06T7/254
Filed: 1992-07-27
Abstract: Objects are observed with an optical, magnetic, electromagnetic or acoustic sensor. The observations are evaluated with a computer. A continuous or discontinuous reference background picture is received by communication of the individual picture data, by means of which the moved objects are eliminated. During the subsequent observation, the continuous pictures are compared with this background picture. Where the actual picture differs in its intensity from the reference background picture, objects are recognised. A selection may take place of specific object types by criteria such as the object size, the contrast or the colour. The expansion and position of the objects in the actual picture are characterised in a grid as coordinates which are either continually stored or directly processed. From the calculated movement paths, the behaviour of the individual objects are numerically characterised and analysed. USE/ADVANTAGE - For quantitative movement analysis of one or several objects, such as fish, in same measurement space. Enables movements of groups of fish to be analysed before and during feeding.

Inventor: BERGER ALEXANDER
IPC: F24S50/20
Filed: 1992-12-02
Abstract: The known sun tracker system with helical groove guide that works according to the gravity force principle is not operational without the daily intervention of an operator, limits the weight of the solar collectors, given the muscular strength required, and thirdly makes the tracking speed dependent from the ambient temperatures, because of the temperature-dependent viscosity of the driving liquid. The disclosed tracker system has a vertical pipe (4), a sleeve (3) provided with a helical groove (16), a guiding element (15), a power block (10) that carries most of the weight of the solar assembly (1) and rotary mast (2), a hydraulic energy accumulator (7) linked by a control valve (9) to a regulating cylinder (5), so that the system can be operated several days independently of outer energy sources, and a thermothrottle (8) that allows the rotary mast to turn at a tracking speed independent from the ambient temperature. This sun tracker system is very robust, has a relatively low energy consumption even in heavy solar assemblies and is very suitable for large-scale applications.
