Title: Method of fastening projections on elements of rubber or the like in sheet form
Inventor: JAEGER ARNOLD
IPC: B29C65/48
Filed: 1987-11-14
Abstract: The invention is based on a method of fastening projections on elements of rubber or the like in sheet form, these elements being roughened and then the projections are bonded to the element by applying pressure. In order to facilitate the preparatory work for attaching the projections, and in particular to improve the roughening operation, according to the invention the elements to be fitted with the projections are provided during their press moulding with a layer of fabric over and beyond the area to be covered by the projections, which is pulled off to achieve roughening. After pulling off the layer of fabric, the elements are coated with an elastomer solution until saturated and then the projections are attached by press moulding.

Title: Process for the production of viewing-window bags and tubular-bag machine
Inventor: RUEGENBERG ROBERT DIPL ING
IPC: B65B9/20
Filed: 1988-05-10
Abstract: The invention relates to a process for the production of bag packs, provided with viewing windows, on tubular-bag machines, with a shaping shoulder for the formation of a wrapping tube consisting of a plane bag web around a feed pipe for filling the bag, and to a tubular-bag machine for carrying out this process, and is intended by the simplest means for making the viewing windows on the bag in one operation with the production and filling of the bag packs. For this purpose, it is proposed, according to the invention, to shape the bag webs around the filling pipe with their longitudinal edges at a distance from one another, to introduce into the interspace between the longitudinal edges of the bag web a transparent-foil web overlapping the longitudinal edges of the latter and to connect the web parts lying one on the other in the same direction to one another to form an endless tube, whereupon the shaping of the bag packs by the formation of a bottom seam, the filling of the bags by means of the filling pipe, the separation of the finished bags from the tube and the closing of their head parts are then to take place in a way known per se (Fig. 2). <IMAGE>

Title: Heatable window pane, in particular of a motor vehicle
Inventor: TRIER FERDINAND PROF DR
IPC: H05B3/84
Filed: 1988-08-23
Abstract: An electrically conducting coating is applied to the heatable window pane, on which two electrodes of comb-like construction are arranged opposite each other, which in each case have a main conductor arranged at the edge of the glass pane. A multiplicity of branch conductors branch off from the main conductor, the branch conductors of the two electrode arrangements are placed at a distance from each other and alternately between each other. The branch conductors have in their free end sections a lower electrical conductivity than in their remaining partial section branching off from the main conductor. The result is that in that region of the pane in which in each case partial sections of higher conductivity overlap each other, a larger current flow takes place than in the other pane regions.

Title: Polishing machine
Inventor: BAREIS MANFRED
IPC: B24B31/033
Filed: 1988-08-25
Abstract: A polishing machine having boxes for receiving the objects to be polished and a polishing medium. The polishing machine has rotatably arranged carriers for the boxes and a first drive arrangement which serves to impart a rotational movement to the carriers. Provided in the carriers are bearings for shafts which are arranged coaxially with the axes of rotation of the boxes. A second drive arrangement serves to impart an independent rotation to the shafts and boxes with respect to the carriers. The boxes are interchangeable, so that the boxes can be equipped with the objects to be polished and the polishing medium outside the polishing machine, while the polishing machine is working. The interchangeability is made possible by the fact that the boxes have at their front ends in each case a coupling for inserting and removing the boxes transversely to their axis of rotation. <IMAGE>
Patent DE-3831693-A1 (DE)
Inventor: SCHMIDT HANS-JOERG DIPL ING
IPC: F25B45/00
Filed: 1988-09-17
Abstract: A method for the non-pollutant discharge of a closed refrigeration apparatus having a refrigeration compressor and a device for carrying out the method. In a known method, a mandrel provided with a longitudinal borehole is introduced into the pressure line starting from the refrigeration compressor and the refrigerant is conducted via this opening into a refrigerant collection tank. It is disadvantageous in this case that the lubricating oil containing dissolved refrigerant remains in the refrigeration system and that this refrigerant is emitted when the temperature rises. The intention of the new method is to remove refrigerant and lubricating oil from the refrigeration system at the same time in a simple manner. For this purpose, provision is made for an opening to be introduced in the region of the lubricating oil accumulation of the refrigeration system (30) and for the lubricating oil to be fed into the collection tank (44) together with the refrigerant. For this purpose, according to the claims relating to the device, a specially constructed extraction head (32) is used. The method and the device allow non-pollutant, complete and rapid emptying of refrigeration systems of the most varied types in a simple manner. <IMAGE>

Suitable photo processes are used to open a window in the second photolacquer film such that the structuring layer is partly exposed. A second structuring layer is deposited by a subsequent oblique vapour deposition of germanium, or a dielectric material. USE/ADVANTAGE - For FET mfr., with low-cost process for narrow low-ohmic gate electrode mfr.

Title: Surge-suppression circuit for switched inductive loads - uses varistor to limit induced EMF and diodes to steer current into ballast-resistor
IPC: H01F7/18
Filed: 1989-09-27
