Inventor: HEIDELBERG GOTZ DIPL-PHYS
Filed: 1989-04-28
Abstract: In an electromotive actuator having a plurality of groups of in each case n coils S1 - Sn, to which in each case one invertor U1 - Un is allocated, in order to be able to form both individual load circuits and group load circuits of different size, group switches 12, 23, 34 ... (n - 1)n are located between the coils S1 - Sn, while isolating switches 11, 11', 22, 22' ... are located between the invertors U1 - Un and the coils S1 - Sn. The individual invertors are each divided into two half bridges 131, 132; 231, 232 .. on the basis of the said switches. If a plurality of coils are connected in series, they form, for example, coil pairs S1, S2; S3, S4 ..., the half-bridge pair which is located on the input side or output side of the coil series circuit being used to drive the coil series circuit. <IMAGE>

Title: Verfahren zur Bestimmung des Vorzeichens der Richtung einer Teilchenströmung
Inventor: HAUSAMANN DIETER DR DIPL-PHYS
IPC: G01P5/00
Filed: 1989-06-18
Abstract: Bei einem Verfahren, bei welchem zur Bestimmung des Vorzeichens der Richtung einer Teilchenströmung ein Heterodyn-Laser-Doppler-Verfahren verwendet wird, wird in einer Interferometeranordnung die Strahlung einer Laserquelle mittels einer als Sendeoptik dienenden optischen Anordnung auf ein Meßvolumen gerichtet. Über dieselbe als Empfangsoptik verwendete, optische Anordnung wird dann durch Überlagerungsempfang ein Frequenzunterschied zwischen der ausgesandten Laserstrahlung und der in die optische Anordnung zurückfallenden Laserstrahlung gemessen; diese zurückfallende Laserstrahlung ist infolge von Streuungen an Partikeln, welche sich in der Teilchenströmung mit derselben Geschwindigkeit bewegen, und infolge des Dopplereffektes frequenzverschoben. Bei dem erfindungsgemäßen Verfahren wird dann der Laserstrahlung alternativ in genau festgelegten Bereichen von Strahlungsverläufen eine zusätzliche Dopplerverschiebung definierten Vorzeichens aufgeprägt, wobei die zusätzliche Dopplerverschiebung vorzugsweise erheblich kleiner ist als die durch die Teilchenbewegung hervorgerufene Dopplerverschiebung. Aus dem zurückgestreuten, empfangenen Laserstrahl wird dann durch Vergleich dieses rückgestreuten Laserstrahls und eines Laserquellen-Referenzstrahls die genaue Richtung der Teilchenströmung bestimmt. Hierbei kann die zusätzliche Dopplerverschiebung entweder einem von der Laserstrahlung abgezweigten Referenzstrahl bzw. Sendestrahl, dem vom Meßvolumen rückgestreuten Laserstrahl oder aber dem in der optischen Anordnung in entgegengesetzter Richtung verlaufenden Sendestrahl und Signalstrahl aufgeprägt werden.

Abstract: Thermoplastic materials having a low dielectric loss tangent and loss index are bonded together using radio frequency energy by employing a polyvinyl chloride buffer above and below the ma­terials being bonded while applying pressure and rf energy. The polyvinyl chloride is a highly plasticized polyvinyl chloride which has a bonding temperature lower than the bonding temperature of the material being bonded. In spite of the fact that the bonding temperature of the polyvinyl chloride is lower than the bonding temperature of the low loss material an effective bond is produced between the low loss material.

Abstract: A cylindrical annular space (202) in a water removal tower (200) contains a column, rotating about a vertical axis, of a sludge layer formed on a belt and laid helically. Between the sludge charge at the upper end onto the belt (210) formed of sections and the discharge at the lower end, the sludge is dehydrated under its own weight and the load of an additional weight placed on top of the column. The laying of the belt and/or of its sections in the annular space is effected by means of bent-up longitudinal edges (212). Within the driven boundaries (206, 208) of the annular space, the revolutions (216, 217, 218) of the layer and of the belt drop. The annular space is bounded by a bottom (230) in a widened part (204) which absorbs the pressure of the column and through which the belt with the sludge passes into an unpressurised zone. On the bottom, the longitudinal edges lay themselves flat. The outlet from the tower is through an opening (224) in a fixed lower part (222) thereof. The device allows water to be removed from large quantities of sludge at low energy consumption.
