Title: Process and apparatus for the circulatory wet treatment of textile material in endless strand form
Inventor: THIES JUN ALFRED
IPC: D06B3/26
Filed: 1981-01-19
Abstract: Process for the circulatory wet treatment of an endless textile strand, together with intensive treatment in treatment liquor, plaiting and renewed intensive treatment. The associated apparatus consists of a treatment vessel for the circulatory guidance of the textile material through an intensive-treatment zone and with a device for the circulatory conveyance of the liquor. The textile material is spread out before being fed to the first intensive-treatment zone, and is guided thus through the first intensive-treatment zone upwards; subsequently, the treatment liquor is squeezed off, and the textile material is folded together and, being transported as a strand laid flat, is picked up, plaited and guided downwards in plaited form, so as to slip on a guide surface, through the second intensive-treatment zone. Further identical circulatory wet-treatments follow thereafter. The first intensive-treatment stage is designed as a stage with an upwardly-directed extension component and the second intensive-treatment stage is designed as a stage with a downwardly-directed extension component. A device for spreading out the textile material is arranged in front of the entrance to the first intensive-treatment stage. The two intensive-treatment stages are designed for guiding through the fully spread-out textile material. A transport winder is arranged in front of the entrance to the second intensive-treatment stage. Feeds for the treatment liquor are arranged on the two intensive-treatment stages.

Title: Method for detecting patterns with controlled measurement data selection
Inventor: MUEHLENFELD EIKE PROF DR ING
IPC: G06V10/426
Filed: 1981-03-27
Abstract: Although an image contains a large amount of information, it is usual to scan the entire image in the form of a raster, for example by means of a television camera, and to enter it into a computer for image analysis or pattern recognition. The visual system of living beings selects the information required in each case by means of saccadic eye movements and thus considerably reduces the flow of information to the brain. Similarly, an object contour is found according to the invention, traced and segmented at the point where contour parameters, for example the curvature, change. Data on contour elements describe nodes on a graph, their positional relation describes the edge between two nodes. By comparison with previously learned graph structures, hypotheses are formed on the type or class of the pattern, and on the position of other contour elements and/or segmenting points of the object hypothesis. The computer drives the sensor to these locations in a saccadic movement and checks the hypothesis in order to either reinforce it or to weaken it. After a few saccadic movements, one hypothesis dominates. The invention is extended to other measurement data and evaluating methods.

Title: Process for the production of anatomically adapted shoe inserts and the use thereof
Inventor: LUTZ NORBERT
IPC: A43B17/00
Filed: 1981-04-13
Abstract: Process for the production of anatomically adapted shoe inserts, such as insoles or side cushions and the use thereof. The still-plastic resin, in particular polyurethane-based or silicon rubber-based, contained in a flexible envelope of the shoe insert is mixed with a curing agent and, if appropriate, with an accelerator, and the cross-linking process of the mixed resin/curing agent and, if appropriate, accelerator system, leading to an elastomeric consistency, is carried out within the envelope, which is tight against resin emergence, and in the associated shoe on the foot of the wearer with the shoe insert in the correct position with respect to the foot. In this process, within a prefabricated shoe-insert envelope, all components of the resin/curing agent and, if appropriate, accelerator system are deposited in the correct mixture ratio with respect to one another, but chemically separately from one another by means of a thin, destructible encapsulation. The encapsulation can then be destroyed mechanically by the exertion of pressure on the shoe insert and/or thermically, by heat treatment thereof. All resin components are then mixed together by deforming and kneading the envelope. The shoe insert thus prepared is made to cross-link or cure in the associated shoe on the foot of the wearer, in the correct position with respect to the foot.

Abstract: The invention relates to a process for achieving an anti-slip means on scaffolding panels or walk boards for scaffolding. In the process, a layer (2), which protects against mechanical loading and atmospheric influences, dries and/or hardens slowly and consists of a lacquer (varnish, paint) or a corresponding material, is first of all applied onto the surface onto which, directly following this and before drying or hardening, coarse sand (3) or a similar granular product, produced, for example, by comminuting mineral materials, is then applied by a scattering procedure or by means of a blower. After the anti-slip layer (2) has dried or hardened, some of the granular product is enclosed by said layer and some of it projects out of the layer. <IMAGE>

Title: Method for displaying continuously changing information items
Inventor: OLBRICH BERND DIPL ING
IPC: G01C21/22
Filed: 1981-10-22
Abstract: The invention relates to a method by means of which continuously changing information items are to be displayed. These information items are, for example, the position and speed of an aircraft which are indicated by means of cross-hairs on a map. Since these information items are not displayed continuously but in each case after a particular measuring time, a delay is produced between the current and the displayed data. To avoid this delay, an extrapolation is carried out by means of a memory and an evaluating circuit so that, for example, the position of an aircraft is continuously displayed on the basis of the trend of the previous variation of the position during the measuring time and after the measuring time has elapsed, the current position data are only used for carrying out a slight correction on the position displayed. <IMAGE>
