Patent DE-2806807-A1 (DE)
Inventor: ECKER HANS
IPC: F28F9/013
Filed: 1978-02-17
Abstract: The spacer grid serves the purpose of mutually fixing tubes (or rods) arranged in bundles in a triangular configuration, e.g. in steam generators or heat exchangers. The individual elements (5) forming the grid each consist of three circular cylindrical tube lengths (6) which are arranged in the triangle and directly joined to one another. The uniform diameter (2a) of the tube lengths (6) is larger than that (2r) of the tubes (3). Each tube length of an individual element is situated between two tubes, but touches only one thereof. Each tube (3) is held by three tube lengths (6) belonging to different individual elements. This spacer grid can be produced using simple means, is of high stiffness and causes only a slight reduction in the free cross-section between the tubes. The tubes, which are free from play in the transverse direction, can expand freely in the longitudinal direction. <IMAGE>

Title: Weft drawing=off drums - have conical shape with yarn guides located radially round them
Inventor: SCHEFFEL WALTER
IPC: D03D47/36
Filed: 1978-09-11

Patent DE-2917198-A1 (DE)
Inventor: KIRCHNER KARL
IPC: B60P1/60
Filed: 1979-04-27
Abstract: In the method, the liquid manure is sucked in by evacuating the interior of the container (1) and is made to flow out by subjecting the latter to pressure. Before emptying, especially during the trip to the land to be fertilised, compressed air is blown into the liquid manure and escapes in the upper region of the container (1), with the result that a swirling of the liquid manure is achieved. To empty the container (1), this escape of air from the container is prevented. Consequently, a swirling of the liquid manure before the emptying of the container is obtained, with the result that the solid fractions of the liquid manure cannot settle on the bottom of the container. No difficulties therefore arise during the emptying of the latter. <IMAGE>
Patent DE-2918524-A1 (DE)
Inventor: REITINGER GOTTFRIED DIPL ING
IPC: H02K19/26
Filed: 1979-05-08
Abstract: Large synchronous machines with sliprings have brush and slipring systems which are connected to one another a plurality of times at one end at high rotor currents. In order to achieve a uniform current distribution between the brush groups and the sliprings, the negative temperature resistance coefficients of the carbon brushes are compensated for by connecting non-reactive resistors in series. At the same time, additional excitation losses are produced, and the machine efficiency thus deteriorates. According to the invention, in order to avoid the above disadvantage, a converter exciter arrangement is specified in the case of which at least two slipring/brush systems (3, 4) are provided. Each of the systems (3, 4) is supplied with direct current from a dedicated converter (7, 8), via a dedicated de-excitation switch (5, 6). The currents which are supplied are detected via measurement transformers (9, 10) and are supplied as the control variable to the associated current regulators (11, 12) which, for their part, regulate the drive units (13, 14) for the converters (7, 8). A differential-current regulator (15) ensures that the same exciter currents flow irrespective of the contact resistances in the two systems (3, 4). <IMAGE>

Title: Contactless measurement of vehicle wheel and steering geometry - uses electronic evaluation of elliptical video images of wheels
Inventor: DITTRICH HOSEF DIPL ING
IPC: G01B11/275
Filed: 1979-12-03
Abstract: The method for contactless measurement of vehicle wheel (1-4) axle and steering (5) geometry data involves forming an image dependent on wheel orientation on a video tube (7,8). The image is then evaluated electronically. The equipment does not require adjustment and enables fully automatic data display. An elliptical image of the outer wheel (1-4) rim circle or a concentric circle is formed for each wheel. The large and small dia. of the ellipse are measured electronically as are the spatial coordinates and those of the point of intersection. The wheel axle and steering geometry data are determined from derived wheel plane and steering axis positions and the known video tube position and wheel dimensions.
