Title: Method for the production of a double-walled tubular hollow body, tools for carrying out the method and a hollow body produced by the method
Inventor: PIEPEN ROLF VAN DER DIPL ING
IPC: F16L9/18
Filed: 1987-10-16
Abstract: Double-walled tubular hollow bodies, particularly those used in the chemical industry, must have a high precision both as regards their axial alignment and as regards the concentricity of the inner wall and must furthermore have a high dimensional stability. If, to form the outer wall, a tube is deformed into a contoured supporting die in the manner of deep-drawing by pressurising the interior with a pressure medium and another tube is then pushed into the deformed outer tube to form the inner wall, the other tube expands radially in a uniform manner until it rests against the outer tube and connects the two of them, and in this way a dimensionally accurate double-walled hollow body is obtained. <IMAGE>

Title: Stress wave gearing
Inventor: MAIER PETER DIPL ING
IPC: F16H49/00
Filed: 1988-05-04
Abstract: The proposal is for a stress wave gearing with a first gearing element (10), which has a circular-cylindrical aperture (11) and on the inner surface of which a deformable tubular second gearing element (12) can be made to roll, the outside diameter of the second gearing element in the undeformed state being slightly less than the diameter of the aperture (11). Rotatably mounted within the second gearing element (12) and concentric with the first gearing element (10) is a third gearing element (13), on which the second gearing element (12) is rotatably arranged and which is deformed essentially elliptically in such a way that it rests at two opposite points on the first gearing element (10). The inner surface of the first gearing element (10) and the outer surface of the second gearing element (12) are of smooth design, at least one of the surfaces having a high coefficient of friction in order to achieve a frictional connection and prevent sliding relative to one another. The elimination of the hitherto customary teeth makes production of the stress wave gearing simpler and less expensive and it is, in particular, possible also to use less expensive materials. <IMAGE>

Title: Method and device for the contactless measurement of the external dimensions of bodies
Inventor: TUTSCHKE UDO DR ING
IPC: G01B11/02
Filed: 1988-05-13
Abstract: In a method for the contactless measurement of the external dimensions of bodies, the body (measurement object) is scanned by a parallel light beam. For this purpose, parallel light is directed onto a slit diaphragm (D), in front of or behind which there is arranged a rotatable, drivable disc (DS) which is equipped with a spiral slot (SS) cutting the slit of the slit diaphragm. The cooperation between the slit diaphragm and the rotating spirally slotted disc produces a pin hole diaphragm (LB) which is moved along the slit at a constant rate when the disc rotates at a constant speed. The external dimension of the measurement object is determined from the time which the beam passing the pin hole diaphragm requires in order to cover the measurement object. <IMAGE>

Title: Process and apparatus for the production of sausage or like foods, in particular for garnishing or decoration
IPC: A22C11/00
Filed: 1988-06-10
Abstract: The invention relates to a process for producing sausage or like foods, in particular for garnishing or decoration and an apparatus for carrying out this process. In order that small amounts of sausage, but also other foods, in particular for garnishing and decoration, can be produced by hand at reasonable expense, according to the invention it is provided that the sausages, immediately after removing the sausage skin successively of some sausages of diverse sausage varieties, are divided into a plurality of pieces by a cut in their longitudinal direction, whereupon the individual pieces of the different sausage varieties are pressed together with a binder in a shared shrink casing to form a uniform sausage. To carry out this process it is preferred that, to cut the sausages in their longitudinal direction, a knife having a plurality of blades is used, which blades are connected together in a frame and are connected to the frame, and that on the inner edges of the frame, shell-shaped holders guide the blades which are arranged at the top and bottom in grooves of holder plates. A combination sausage results from this which can be composed of the most diverse known sausage varieties which are not, however, mixed together but are nevertheless firmly joined together and are therefore highly suitable for garnishing and decoration.

Patent DE-3904357-A1 (DE)
Title: Distributor apparatus for falling-film evaporators
Inventor: KOHLER WOLF-ULRICH DR ING
IPC: B01D1/06
Filed: 1989-02-14
Abstract: In falling-form evaporators of relatively large size, it is not entirely simple to distribute the medium to be evaporated uniformly over all the evaporator tubes (2). In the case of the distributor troughs previously used - especially when these have outlet branches (9) - distribution problems arise due to fabrication and assembly inaccuracies, transport delay and bending of the trough bases during operation. The object underlying the invention is to be able to permit relatively large fabrication tolerances, to make possible horizontal installation without problem and to ensure uniform juice level over the entire trough base. In a distribution apparatus of the type described at the outset, this object is achieved by the trough (5) nearest to the tube sheet being composed of segments (10) each of which are supported by a three-point support to be adjustable in height and are detachably attached together. The distribution device according to the invention is suitable in particular for large falling-film evaporators, independently of their sector of use. <IMAGE>
