Patent DE-3100349-A1 (DE)
Title: Ball screw with internal tubular return
Inventor: KAISER SIEGMUND H ING GRAD
IPC: F16H25/22
Filed: 1981-01-08
Abstract: A ball screw has a ball screw spindle and a ball nut, the helical tracks of which form 360 DEG  ball tracks with an approximately S-shaped return location, at which the balls are raised out of the spindle track by means of deflection surfaces on both sides, between which the ball track is covered, through an opening in the shoulder separating the turns of the nut track into a deflection recess in the material of the nut. In one exemplary embodiment, a deflection insert in the form of a sheet is inserted in the annular gap (2a) between the nut (3a) and the spindle (1a) at each return location and this insert comprises a pair, assigned to the respective return location, of deflection fingers (28, 29) which point in opposite directions, are bent relative to the spindle track and reach into the latter. The part of the insert which connects the fingers (28, 29) forms the cover (26). In the other case, two bead-shaped inserts which are inserted into the turns of the nut and spindle tracks and the ends of which, which lie obliquely opposite one another, form deflection surfaces, and at each return location. Lateral projections of the inserts engage in the annular gap via the interruption in the shoulder and form the cover for the ball track relative to the spindle. Each insert is assigned to two adjacent return locations. <IMAGE>

Title: Edge filter
Inventor: HUENTEN DIETER DIPL ING
IPC: B01D29/15
Filed: 1981-07-08
Abstract: An edge filter for lubricating oil or the like having a cylindrical rotatable filter insert is to be cleaned in the closed state by flow reversal at a part of the filter surface. During normal operation, the entire filter surface is to be available for action. The solution is a U-shaped profile which permanently lies against the filter insert with one arm and thus on rotation of the filter insert serves as a scraper and which for cleaning is pressed with both arms against the filter insert so that a wash channel results which is connected to a flushing orifice and through which a backwash through the filter surface can be produced. When two such filters are combined, an expedient apparatus is provided for continuously operating machines. In the drawing, in Fig. 1, the filter is depicted in cross-section in normal operation, in Fig. 2, the filter is depicted during washing in cross-section and, in Fig. 3, the filter is depicted in longitudinal section. <IMAGE>

Title: Device for the continuous pressing of a mat of material in the course of producing chipboards, fibreboards and similar pressed material
IPC: B30B5/06
Filed: 1981-08-26
Abstract: The invention relates to a device for the continuous pressing of a mat of material in the course of producing chipboards, fibreboards and similar pressed material. The device includes a press upper part with an upper platen and a press lower part with a lower platen. Press belts are guided circulating on the one hand around the press upper part and on the other hand around the press lower part and form a press gap with feed region. A feed gap which is half-trumpet-shaped in the vertical section is formed on the upper platen in the feed region. This feed gap merges into the press gap in the feed direction. The upper platen possesses, in the feed region, a gap chamber which is open at its feed side. Said gap chamber forms a feed tongue towards the material to be pressed. The feed tongue is curved upwards and the feed gap is defined by this means. <IMAGE>

Title: Method of producing a slab of cement-bound material
Inventor: VOIT ERWIN
IPC: B28B7/00
Filed: 1981-12-15
Abstract: The invention relates to a method of producing a slab from a material which contains at least cement and solid aggregates, in which method, in order to obtain a raised surface, the setting of the cement on at least one surface side of a slab blank produced in a mould is delayed by applying a retarder and the surface side is raised. The invention is distinguished by the fact that, to produce a structure consisting of several raised surface areas and intermediate recesses from exposed concrete, a slab blank is produced which has prominent areas and recesses on the surface side, and that the slab blank, in order to apply the retarder to this surface side, is put on a surface to which the retarder has been applied beforehand. <IMAGE>
