Patent DE-4235824-A1 (DE)
Inventor: SCHACHTL MARTIN
IPC: G01B21/08
Filed: 1992-10-23
Abstract: The invention concerns a method for measuring the thickness of a coating on paper (12) coated by means of a blade-like element (20) which applies the coating composition to a web of paper (12) as it passes over a roller. The invention calls for the deviation of the blade (20) to be continuously determined near the blade tip (36) by non-contact measurement. This enables the distance from the blade edge to the surface of the paper (12) to be continuously determined by simple trigonometric calculation and, from the fixed relationship between this distance and the coating thickness, the coating thickness to be continuously determined in the immediate vicinity of the applicator (18, 26). The invention also concerns a device designed to carry out the method and a particular use of this device for the simultaneous determination of the viscosity of the coating compound.

IPC: H01H73/22
Filed: 1993-01-25
Abstract: The protective device described has at least one sensor (sensor H, temperature sensor R1) which delivers an electrical signal to a control circuit. The sensor is of particular use in determining the operational status of an electrical consumer, in particular a rotary-pump motor, a slotted-tube pump motor or a fan motor (pump motor M).

Title: Coupling arrangement for two-way optical communication using double-refracting prisms
Inventor: BOLZE THOMAS DR
IPC: G02F1/09
Filed: 1993-03-17
Abstract: In known coupling arrangements, signal power losses of about 50% occur in each case in the coupling between two input paths and at least one output path or in the opposite direction. According to the invention, a coupling arrangement comprising two double-refracting prisms with one Faraday rotator disposed between them is proposed which has no system-related power loss. Through the coupling arrangement, not only the light from one laser diode but also from two laser diodes can be coupled into an optical waveguide so that with corresponding arrangement or control of these laser diodes, polarisation division or wavelength division multiplexing is also possible. <IMAGE>

Title: Fluidised-bed reactor for the aerobic purification of waste water
Inventor: LANGHANS GERHARD DR
IPC: C02F3/12
Filed: 1993-09-29
Abstract: A fluidised-bed reactor in a vertical, cylindrical construction is described for the aerobic purification of waste water, in the interior of which are situated partitions and fluidisable support bodies. In order also to ensure problem-free purification of solids-containing waste waters, two partitions I and II are arranged axially parallel below the liquid surface in the reactor. The partition I extends to the reactor bottom and forms together with the reactor wall a segment-shaped chamber (7) into which opens the outlet (4) present on the reactor head. The partition II reaches approximately to the centre of the reactor height and is arranged in such a way that a flow-through opening remains between it and the bottom. The bottom is inclined on one side in the shape of a segment so that a sloping bottom segment (2) and a horizontal bottom segment (3) result.

Title: Cell for measuring zeta-potential
Inventor: KOERBER HEINZ
IPC: G01N27/447
Filed: 1993-12-23
Abstract: The invention relates to the field of physical chemistry and instrument design and concerns a cell for measuring zeta-potential. The object of the invention, to specify a zeta-potential measuring cell by which it will become possible to determine the zeta-potential on samples with the smallest possible area, is achieved by virtue of the zeta-potential measuring cell according to the invention, which contains a body that has at least two through-bores which are at an angle of 90 DEG  with respect to each other and intersect. Two pistons which can be rotated and displaced are fitted into one through-bore as far as the measuring-gap width. The end faces of the pistons in the body are planar and mutually parallel and a sample is applied onto each of them. The other through-bore is designed as an inlet and outlet channel for an electrolytic liquid, in each of which an electrode is located. The valid flow condition is that the flow resistance in the measuring gap is large compared to the flow resistance in the rest of the system through which flow takes place.

IPC: H01H50/28
Filed: 1994-02-11
Abstract: A spool (2,3,32,33) with an iron core (5) is arranged on a base body (1,31). Both ends of the core (5a,5b) are each connected to a pole shoe (6,7) outside the spool. A permanent magnet (10) is arranged next to the spool (2,3,32,33). This generates a pole (S) of the same sign at each pole shoe (6,7) and an opposite pole (N) in the middle between the pole shoes. A rocker armature (11) is pivotally mounted near the middle pole and forms an operating gap (27,28) with each pole shoe (6,7). A contact spring (13,35) is fixedly coupled to the armature (11). The contact ends (31a,35a) cooperate with at least one counter-contact element in the base (1). The contact spring (13,35) is directly connected to the armature (11). An extension of the spring (13,35) forms a bearing section (13b,13c,35b) for the armature on the unit formed by the pole shoes (6,7) and the permanent magnet (10).

IPC: D01H1/32
Filed: 1994-06-13
Abstract: An electrical drive for a process machine, for example a spinning machine (10), having a frequency converter (30) which is connected to an electrical power supply network (36a) and supplies alternating current at a supply freqency which varies with time to motors (16, 18) has a controller (32) which records disturbances via sensor lines (40...46).
