Patent DE-3900668-A1 (DE)
Title: Press for laterally upsetting workpieces, in particular slab-upsetting press
Inventor: KERSTING EMIL
IPC: B21J13/08
Filed: 1989-01-09
Abstract: The invention relates to a press for laterally upsetting workpieces, in particular slab-upsetting press, consisting of a press frame, in which upsetting tools driven in opposite directions by eccentric shafts are arranged on both sides of the workpiece in tool carriers guided displaceably in the press frame, the spacing of their spindles arranged between the tool carriers and eccentric shafts being adjustable, and also having devices for displacing and holding the workpiece during or between the upsetting steps. In order to improve hitherto known slab-upsetting presses as a whole, so as to obtain optimum deformation of the workpiece to be upset and so as to increase the efficiency of the press, for which purpose the feeding and holding of the workpiece during or between the upsetting operations is to be optimised and the changing times for the workpiece are to be shortened, it is proposed that the press frame is divided up into two press-frame halves (2, 3) which are arranged axisymmetrically to the tool and are interconnected via four columns (8, 9) running parallel to one another and in the upsetting direction, and that the devices for the stepwise advance of the workpiece between the upsetting steps and for holding the workpiece during the upsetting operation are arranged on the columns. <IMAGE>

Title: Threading and holding system for curtains
Inventor: AHLSTICH STEFAN
IPC: A47H13/00
Filed: 1989-01-26
Abstract: Devices for threading on and unthreading curtains are based either on the commercially available circular curtain-rail openings, so that the approach angle is unfavourable and the threading-on/unthreading is possible only in jerky fashion, or have so-called inlet sluices which, however, require expensive refurnishing with special curtain rails. The new threading and holding system is intended to facilitate the threading-on and unthreading, washing and drying of curtains, to have a high functional reliability and also be usable retrospectively for commercially available curtain rails which have already been mounted.   The opening in the curtain rail (1) is configured as a slot (2), into which the connection head (7) of the circular-arc-shaped threading device (4), which possesses an additional fixing bracket (8), engages. The slot can be closed by a separate closure part (3). A transfer tube (5) can be attached (26) to: the threading device (4), the holding spiral (6) and the drying tubes (5a). The threading and holding system is suitable for the threading-on and unthreading of curtains and also for the fixing of the curtain runners during the washing and drying of the curtains. Curtain rails which have already been mounted can be retrofitted by a simple milling or drilling operation. <IMAGE>

Title: Locating centre
Inventor: BRUCKNER MANFRED
IPC: B23B23/02
Filed: 1989-03-03
Abstract: In order to avoid as far as possible, in the case of a locating centre (1) consisting of a carbide tip (3) and a base body (2), the risk of the carbide tip (3) breaking off the base body (2), a centrally arranged reinforcing element (10) is inserted at least in the carbide tip (3). The reinforcing element (10) passes through a plane defined by a shoulder (9) of the carbide tip (3), in which cracks normally occur due to overloading, vibrations or the like, and ensures that the partial sections of the carbide tip (3) are held together despite a possible fracture. Advantageously, the reinforcing element (10) engages in a bore (11) in the base body (2). <IMAGE>

Title: Resilient pressure sleeve with shaped head
Inventor: BARTHA ISTVAN
IPC: B44B5/02
Filed: 1989-04-06
Abstract: The resilient pressure sleeve with shaped head is a pressure and pressure-relief piece, used in tool construction, general machine construction, in robots etc. as an oil seal, position holding device and ejector piece. With two opposing grooves and two wings at the end of the threaded bolt, the pressure sleeve enables the shaped head to be secured against rotation and the part being produced to be pressure-relieved or pressed without undesired marking. The shaped head can have any desired size irrespective of the pressure sleeve or the bore. The invention makes possible an optimally small space requirement for building in. By means of the best possible guiding of the pressure sleeve, the whole external surface can take up axial forces and pressure stresses.

Patent DE-3942804-A1 (DE)
Inventor: JOUCK WALTER DR
IPC: C09D133/04
Filed: 1989-12-23
Abstract: The invention relates to a process for producing a multi-layered coating, using a pigmented aqueous base coating composition containing a water-dilutable emulsion polymer as film-forming material. The water-dilutable emulsion polymer is obtained by two-stage emulsion polymerization. In the first stage, a polymer with a glass transition temperature (TG1) of +30 to +110  DEG C is produced. In the second stage, a monomer mixture which, if polymerized alone, would yield a polymer with a glass transition temperature (TG2 of -60 to +20  DEG C is polymerized in the presence of the polymer produced during the first stage. The hydroxyl number of the emulsion polymer is between 2 and 100.

IPC: A63B59/40
Filed: 1990-04-11
Abstract: The table tennis bat has differently shaped grip shells (14, 16), by which the forehand and backhand sides of the blade (10) are defined. In contrast to known anatomical grips, however, the grip shells (14, 16) have very simple geometrical shapes. With the grip shaped, in the central region, substantially symmetrically to the medium lengthwise axis, the grip shell (16) on the backhand side is designed with an approximately uniform thickness up to its leading edge (22). It also extends beyond the forward-chamfered front end of the grip shell (14) on the forehand side. In order nevertheless to be able to attach coverings of equal size on both sides of the blade, the front region of the grip shell (16) on the backhand side is undercut. <IMAGE>

Title: Hot and cold water mixing tap - has stop to prevent excessively rapid closing of water supply
IPC: F16K11/078
Filed: 1990-12-03
Abstract: The hot and cold water mixing tap has a housing (1) with two inlets (2) for the hot and for the cold water and an outlet (3) for the mixed water. The volume of the outflow is controlled by a slider (10, 11) which is actuated by a lever (16).

The water in this cylinder can flow slowly out through a small orifice (31), thus allowing the piston to be pressed into the cylinder. There is a spring between a movable catch and the mixing vanes.
Patent DE-4038700-A1 (DE)
Inventor: RITTER WOLFGANG DR
IPC: C09J103/00
Filed: 1990-12-05
Abstract: A simplified process is disclosed for producing starch-containing dispersion glues in a redispersable dry form from a mixture of aqueous dispersions of synthetic polymer compounds having an adhesive character and of water-containing starch and/or starch derivates. The process is characterized by the fact that starch and/or starch derivates are used as finely powdered solids, blended with the aqueous polymer dispersions and if necessary with other low-molecular plastifiers. The mixture of several substances is subjected at high temperatures and pressures, at the same time as it is intensively blended, to starch hydrolysis, in order to obtain thermoplastically processable starch, and if necessary the homogenized polymer mixture is shaped out of the melted phase and/or is further ground. Also disclosed are meltable and/or redispersable dry glues that may be produced by this simplified process.
