Patent DE-3802914-A1 (DE)
Title: Track chain (endless track, crawler chain, caterpillar chain)
Inventor: PIETZSCH LUDWIG DR ING
IPC: B62D55/21
Filed: 1988-02-01
Abstract: The invention relates to a track chain, the chain links of which have three tubular bodies (2, 4) which are arranged transversely to the direction of travel and are connected to the chain links, which are adjacent in the direction of travel, via connectors (10, 12) and via pins (8) extending over the width of the chain. The track chain is distinguished in that only the outer tubular bodies (2), looking over the width of the chain, are provided on the track side with track cushions (5) and in that these track cushions and the outer tubular bodies (2) are designed such that the track cushions are installed by being slid laterally onto the outer tubular bodies. This results in a track chain which is lighter than conventional track chains with two tubular bodies, or just one tubular body per chain link but nevertheless permits the tried and tested installation and removal of the track cushions (5) from the side. <IMAGE>

Title: Control of a welding robot
Inventor: ISHIDA MUNEO
IPC: G05B19/02
Filed: 1988-02-17
Abstract: A welding robot is specified which contains a working area which has a welding gun and an actuating cylinder in order to press the welding gun in the direction of a workpiece to be welded.

The welding control parameters are applied to a clock-controlled operating device which controls the welding gun and the actuating cylinder in accordance with the welding control parameters which it receives from the control device. A sequence control device is provided which receives a welding start signal from the control device and transmits the welding start signal to the clock-controlled operating device in order to initiate the welding operation.
Patent DE-3806891-A1 (DE)
Title: Root filling system (dental)
Inventor: SCHEPPERHEYN HENDRIK
IPC: A61C8/02
Filed: 1988-03-03
Abstract: The invention relates to a root filling system comprising a guide with drive for the drill lowering means, drill lowering means and root post. The guide with drive has the task of guiding the root post axially and thereby achieving axis-parallel preparation of the dental root. In the apical part, the drill lowering means is subdivided into several, preferably cylindrical, portions which taper in the apical direction and in their entirety approximate to the conical shape of the dental root. It may be longer than the dental root in order to prepare the jaw bone for the screw thread of the root post. The lowering head has a concave depression on the surface facing the dental root. The root post tapers in the apical direction in several portions, of which one or more are provided with a, preferably tapping, screw thread. The head of the root post is concave on the side facing the dental root in order to engage around the annular protuberance on the dental root formed by the drill lowering means. The root filling system thus causes stabilization of the filling and makes it possible to use thinner root posts in the apical part, which serves to retain the dental substances as much as possible. The pulp is tightly closed. Use of fixing cements or similar aids is largely avoided.

Abstract: Light guide consisting of a spiral fibre bundle whose jacket consists of plastic, and which is elastically expandable in the axial direction of the spiral, in which the optical fibres are surrounded by the jacketing in such a way that the individual spirals have a radius which, in a range from the relaxed state to the state of maximum expansion of the spiral, is greater than the smallest radius which produces a non-negligible impairment of the light conducting capacity due to the failure of total reflection on the outer surfaces of the fibres - that is to say the curvature-induced damping losses are negligibly small with respect to the fibre-specific damping losses, and the optical fibres are prestressed (twisted) spirally or helically in such a way that, when the helix is stretched from its relaxed position, they relax with respect to the pretorsion, at least in an initial region of the stretching. <IMAGE>

In accordance with the desired taste, greater or lesser amounts of the individual ingredients are selected to produce the base mass. Further ingredients which lead to a rounding-off of taste, are possible, in addition enhancement to achieve a particular component as a "highlight".

Patent DE-3840290-A1 (DE)
Title: Process for recording and/or reproducing data signals
Inventor: FELL WOLFGANG DR ING
IPC: G11B20/00
Filed: 1988-11-30
Abstract: A process for recording and/or reproducing data signals is specified, in which the advancing speed of a magnetic tape is changed in comparison with a normal advancing speed by a factor of 1/n. The static track angle of the magnetic tape wrapped helically around a tape guide drum is also changed with the advancing speed in such a way that a track path followed by rotating magnetic heads coincides with that of a particular track format. The data rate of the data signal picked up from the magnetic tape or of an applied data signal is converted by the factor n by insertion of a store into the data stream.

Inventor: SADLACK WERNER
IPC: D05B35/04
Filed: 1989-01-24
Abstract: To attach a strip of material (66) provided with a slide-fastener part (67) to the front of a pair of trousers (103), firstly an edge (81) of the strip of material (66) and then the edge (107) of the front of the pair of trousers (103) are folded over. In this case, the strip of material (66) is arranged above the front of the pair of trousers (103). Both the folded-over edges (81, 107) are placed in a position relative to one another which they will assume relative to one another after they have been joined. They will then be brought to rest against one another and sewn with only one seam in only one sewing operation. As a result, a very simple handling of the parts to be sewn together and a very simple construction of the sewing unit required for this purpose are achieved. <IMAGE>

Filed: 1989-02-14
Abstract: A sectional bar with at least one rigid gusset is composed of a flat bottom (101) with two opposite legs (102) that extend at an angle to the bottom and end each along their top edge with a flange (103) that extends parallel to the bottom. The flange is if necessary provided along its outer edge with an edge (104) that forms an angle to the plane of the flange. The sectional bar is cut in such a way that a rigid gusset is obtained by bending around the bottom or the plane of the flanges. This makes the sectional bar useful for a variety of applications, for example a plurality of assembled sectional bars with a right-angled gusset form a mobile flood protection dam.

Title: Variably deformable bone contact layer for prostheses
Inventor: LIEKE MICHAEL DIPL ING DR
IPC: A61B17/68
Filed: 1989-02-15
Abstract: The invention relates to a prosthetic component which is preferably provided for the cementless anchorage of prostheses, above all hip joint components (cup, stem) and knee joint components. It is made of a bone-compatible material or is provided with a bone-compatible coating. The invention is intended, in particular, for dowel-like or case-like anchorage elements which can be braced by an internal spreading body. For this purpose it is provided that the bone contact layer can also be spread in a defined extent. In order to permit spreading of this layer (and the layers lying underneath it) there is a superficial fine and/or coarse structure in which the distance between two arbitrarily definable points can be extended. Among others, wavy surfaces are preferred, so that extension of the surface and hence spreading of the overall structure is possible by stretching the particular waves. Provision is made for attachment of further prosthetic elements on the inside; provision is made for applying a layered coating including integration of elastic damping elements.

Title: Cleaning system for screening machines - uses periodic increase in tension of screw mesh to free blockages
Inventor: BLACHETTA WOLFRAM
IPC: B07B1/48
Filed: 1990-01-17
Abstract: To clean the sieve mesh periodically during the operation of the screening machine the tension of the sieve mesh is temporarily increased above the tension required for sifting.  Any material blocking the screen holes is freed through the different vibration. When the screen tension is increased the frequency and/or amplitude of the exciter unit can also be varied, in particular increased. The screen mesh can have tension folds at the narrow sides which can be engaged by tension hooks on the machine frame. One hook can be rigidly mounted and the other movable so that it can be adjusted by a setting member to alter the tension. ADVANTAGE - The cleaning action is produced without damaging the screen mesh.
