Patent DE-3642757-A1 (DE)
Title: Process for product monitoring of melt-extruded plastics by monitoring the dynamic viscosity of the melt in the extrusion system
Inventor: SCHIPPERS HEINZ DR ING
IPC: B29C48/05
Filed: 1986-12-15
Abstract: A process and a device for product monitoring of melt-extruded plastics, in particular chemical fibres, is proposed, in which the dynamic viscosity of the melt at the end of the melting extruder is monitored. In a measurement zone of the melt stream leading to a consumer, the pressure loss and the temperature are measured for this purpose and input into a computer. Since with constant delivery of the melt from the measurement zone by means of a volumetrically operating metering pump, the pressure loss is directly proportional to the viscosity, a good opportunity is provided for monitoring the effects of the extruder operation on the product quality and, by corresponding interventions, of controlling the melting process with the object of providing the desired quality.
Patent DE-3709977-A1 (DE)
Title: Loop gripper for tufting machines
Inventor: SCHINDLER HEINZ
IPC: D05C15/22
Filed: 1987-03-26
Abstract: Known loop grippers for tufting machines abrade the needles cooperating with them, so that these acquire sharp edges which cut into the substrate of the tufting fabric and damage this, whilst, on the other hand, the loops picked up by the loop gripper are not cut open reliably and cleanly. The new loop gripper is to eliminate these disadvantages in a simple way. In the loop gripper, the hook, which cooperates on the one hand with a needle and on the other hand with a shearing knife, is provided with undercuts in the region of the tip and of the cutting edge. As a result, the needle comes into contact with the hook only over a very short length and therefore experiences scarcely any abrasion, so that the feared sharp edges no longer occur. On the other hand, a clean cut of the loops picked up by the hook is guaranteed, because the knife can cooperate under prestress with the cutting edge in a simple way.

Title: Printer table with continuous-paper selection shelf rack and multi-chamber paper holder
Inventor: MACKERT REINHOLD
IPC: B41J11/58
Filed: 1988-02-13
Abstract: For different uses, it is necessary, depending on the task in hand, to feed computer printers with different types of paper. Without the printer table with continuous-paper selection, in such a case the paper stack situated under the printer table must be exchanged for the required continuous-paper block. Because of the effort involved in this, a paper change is in most cases not carried out. Expensive special paper becomes all-purpose paper. By means of the printer table with continuous-paper selection, the paper change becomes effortless and the operator of a printer is able to insert the particular paper suitable for his requirements.

Title: Vibration damping in loudspeaker housings by means of the bracing connection of opposite housing walls
Inventor: KOSCHWITZ WALTER
IPC: H04R1/02
Filed: 1988-05-27
Abstract: The damping of loudspeaker housings according to the invention can self-evidently be undertaken in a plurality of axial directions. In this case, it is not necessary that the introduction of force takes place at the centre point or on a central axis of the housing wall to be damped. For connecting the housing walls, as many connecting rods as desired can be used. Intersections at a point are intended to be avoided, in order to make special constructional measures unnecessary. It is self evident that the positioning of the connecting rods is also determined by the position of the loudspeaker. The mechanical design of the connecting rods offers manifold possibilities: screws and tubes with inner threads, hexagonal-head screws, cross-head screws, cap nuts, etc., without thereby altering the characteristic features of the present damping methods.

Title: Single-part, multiply adjustable pipe-securing means without additional parts in the closure
Inventor: GOERG HELMUT
IPC: F16L3/14
Filed: 1988-09-21
Abstract: A specially profiled band is intended to be designed such that a "single-part, multiply adjustable pipe-securing means" is obtained, the intention being for no additional parts to be used in the region of the closure. The closing or opening procedure is intended to be effected by means of a screwdriver or similar article, an inwardly inclined closure protrustion engaging into a special profile band. In this arrangement, the screwdriver or similar article is to be guided such that injury is ruled out completely. Said single-part, multiply adjustable pipe-securing means is, furthermore, capable, by virtue of its adjustability, of drastically reducing the need for special sizes of pipe-securing means. All these requirements can be totally fulfilled by this invention cleanly, simply and cost-effectively.

Title: Knee joint prosthetic components as replacement for the cruciate ligaments
Inventor: LIEKE MICHAEL DIPL ING DR
IPC: G09B23/32
Filed: 1988-12-01
Abstract: The invention relates to connecting elements for a knee joint endoprosthesis for connection of the femoral component to the tibial component for the total or partial functional replacement of the cruciate ligaments, which essentially comprise mobile components. The entire range of movements of the anatomically normal knee joint is to be achieved by these artificial cruciate ligaments, so that the natural movements in the knee joint, including the physiological terminal rotation, can (are to) be largely simulated. For this purpose, the shapes of the knee joint, above all in the region of the sliding surfaces and in the region of the intercondylar eminences, including the femoral, tibial and patellar joint surfaces, are adapted to suit the shape of the physiologically-anatomically normal knee. The shapes of the cruciate ligaments and their points of attachment, the course of fibres and, if appropriate, the load-bearing capacity imitate the anatomically normal cruciate ligaments. With the precondition that these artificial shapes exactly imitate the normal knee, this results in movements in the knee joint which simulate the physiologically normal movements in a sufficiently exact manner. These artificial cruciate ligaments are to make a contribution to optimising the knee joint endoprosthesis for prevention of premature loosening of the prosthesis due to physiological movements and physiological loads.
