Patent DE-3918290-A1 (DE)
Title: Continuous lime slaking plant
Inventor: BRANDAUER GEORG ING
IPC: C04B2/08
Filed: 1989-06-05
Abstract: A lime slaking plant has a (pref. multistage) mixer associated with a wet scrubber equipped with water spray nozzles, the time dust-enriched sprayed water being fed as slaking water to the mixer. The novelty is that a fresh water line, located outside the scrubbing chamber of the wet scrubber, is connected via. a pump to the nozzles, the spray angle of which corresponds to the angle (e.g. 90 deg.) of the roof-like sloping sidewalls of the scrubbing chamber. The lime dust-loaded water is discharged from the wet scrubber into the slaking water inlet of the mixer. A speed-regulated  compartmental wheel meters lime to the lime inlet  of the mixer and is located between the lime silo, which is pref.  a level-controlled intermediate silo connected by a feed screw to main silos and the mixer. Also claimed is a lime slaking process in which a constant amount of fresh water is fed to the nozzles and then fed directly as slaking water into the mixer, the lime amount being varied to maintain a continuous complete slaking operation.
Patent DE-3920287-A1 (DE)
Inventor: ECKERT HORST DIPL ING
IPC: B62D61/12
Filed: 1989-06-21
Abstract: 2.1 The axle load of such a drive axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the insertion depth of the slide of an electrical displacement sensor into the stator and thus determines the axle load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution. 2.2 In order to simplify the known device, the present invention proposes the replacement of the three-dimensional characteristic diagram by a two-dimensional contour (20, 21) and a displacement capability of the stator (25) of the displacement sensor (24) as a function of the pressure of the lifting bellows (1). As a result, a pressure-dependent adjustment of the insertion depth is superimposed on the adjustment of the insertion depth of the slide (22) by the contour (20, 21). The preferred area of application is vehicle technology. <IMAGE>

Title: Paper-making blanket yarn - has side sections extending from centre to overlap for permeability and weave in place without distortion
Inventor: SALMINEN ARI
IPC: D21F1/00
Filed: 1990-10-05
Abstract: The yarn, to be used in the warp and weft of a drying blanket for a papermaking machine, has a cross-section with a reinforcement section (1) and one or more side sections (2) extending from the first section (1). The smallest dia. of the side section at right angles to the main plane of the material to be  woven is significantly smaller than the max. dia. of the reinforcement section in the same direction. This allows a partial overlapping of the warps and/or wefts on a line at right angles to the fabric plane. The side sections (2) of the yarn taper to a point away from the junction with the reinforcement section (1), and the edge of a warp is taken through a cross section point (I) of the side section (2). The outer surfaces of the side sections run symmetrically from the junction with the reinforcement section (1) to the yarn edge, and the side section (2) is symmetrical to a line through the centre of the section, and the outer surfaces (4) meet at the point edge (K). The outer edges (K) of the side sections (2) are aligned with the centre line (VK) passing through the yarn on the fabric plane, to give two equal sections on either side of the reinforcement centre (1), pitched at the same or different directions in a mirror image. The reinforcement section (1) is a polygon, square, a rectangle, a circle, an ellipse, an oval or a knotted form. The outer surface (4) of a side section (2) has flat and/or curved planes as a concave or convex profile. ADVANTAGE - The yarn structure gives the fabric a good permeability and is woven without distorting the lie of the warps as the wefts are inserted.
