Patent DE-3811834-A1 (DE)
Title: Method and apparatus for resistance projection welding with quality monitoring of the welding
Inventor: WINTER PETER DIPL ING
IPC: B23K11/25
Filed: 1988-04-07
Abstract: Resistance welding methods were hitherto scarcely suitable for carrying out quality monitoring of the welding in the welding machine during the continuous production. This was because of the welding and measuring methods, which did not permit measurement of the joining occurring between the welded parts, because, during the welding, on the one hand the welded parts thermally expand due to their pronounced heating and on the other hand the plasticised material is deformed by the electrode pressure forces. In a procedure according to the novel method, the quality monitoring of the welding is made possible directly following the welding operation. In a resistance welding method with welding energy density optimised by spatial limiting of the welding zone and by minimum welding duration as well as maximum reproducibility of the welding parameters, the depression displacement of the welded parts into one another is measured by a high-resolution displacement sensor. This depression displacement is the best suitable measuring variable in order to determine the extent to which the parts to be welded have joined to one another. With uniform preparation of the welded parts and welding parameters set once to the welded parts, quality monitoring which goes beyond the method according to the invention is only necessary in exceptional cases. Quality monitoring of the welding.

Title: Process and apparatus for producing foldable articles, such as book covers, files, folding containers or the like
Inventor: HINTERSEER HEINZ DIPL ING
IPC: B29C37/00
Filed: 1988-04-19
Abstract: The process serves for producing foldable articles, such as book covers, files, folding containers or the like. A welding apparatus permitting the use of thermoplastic material to be welded, in particular polypropylene to be welded, is used. This apparatus comprises a welding tool (12, 12'), which can be heated to the desired welding temperature, and a counter-tool (14, 14'), which can be set to a temperature which lies below the melting point of the material to be welded and has a profiling (15) corresponding to the desired welding or embossing contour and, if appropriate, also a cutting edge (16). Furthermore, also provided is a thermally conductive heat-resistant separating layer (13, 20), which is assigned to the welding tool (12) and through which the thermal energy required for plastifying the material to be welded can be fed to the said material and from which it can be detached after its cooling. Particularly simple production of inexpensive but nevertheless aesthetically pleasing articles is achieved by the exclusive use of material to be welded in the form of multi-wall sheets (1), having two sheets (2, 3) joined to each other by means of webs (4) and consequently kept at a distance from each other, and also by the sheets initially being softened locally by the heated tools (12, 12', 14, 14') along the intended path of the outer contours of the articles and also the intended path of the folding lines (10), and with simultaneous deforming and softening of interposed...

Title: Process and device for treating a hydrocarbon/air mixture
IPC: B67D7/04
Filed: 1988-07-19
Abstract: The invention relates to a process for reducing essentially hydrocarbons in an air mixture containing these hydrocarbons using the known membrane method. The main aim is markedly to decrease the previously required large surface areas of the semipermeable membrane. This is achieved by first feeding the arriving mixture to be purified to a compressor and feeding it from this, compressed, to a downstream condensation device and there separating out a condensate with cooling, whereupon the residual mixture depleted by the condensate is fed to the membrane and the permeate formed at the membrane is returned upstream of the compressor, while the condensate is fed to a receiver and from there at least some is conducted away to the outside.

Title: Process for purifying surfactant-containing oil/water emulsions
Inventor: KLEIN HANS PETER DIPL PHYS DR
IPC: B01D17/035
Filed: 1988-09-22
Abstract: Oil/water mixtures containing cold cleaners (cold-solvent cleaners) cannot be treated mechanically (coalescence, flotation). With the aid of a three-stage process, comprising initial ozonisation, coarse deoiling and final ozonisation, it is possible to treat such synthetic oil/water mixtures in accordance with the legal requirements. The emulsion is broken in the intitial ozonisation stage so that the oil is present free in the water. In the second stage, the majority of the oil can be mechanically removed. Residual hydrocarbons are converted by the third stage, the final ozonisation. The purified water is suitable for direct introduction into the sewage system. To treat 1 m<3> of synthetic oil/water mixture containing 150 mg of oil/l and 160 ppm of cold cleaners, in total 2.1 m<3> of ozone-containing gas are required, containing 100 g of ozone, for the first and third stages. Oil/water mixtures arising in practice require more ozone because of additional water constituents. <IMAGE>

Title: Machine for treating board-like objects, especially for producing printed circuit boards
Inventor: HAAS RAINER ING GRAD
IPC: H05K13/00
Filed: 1988-12-20
Abstract: A machine for treating board-like objects, especially for producing printed circuit boards, includes a roller conveyor system which includes in its turn a multiplicity of pairs of rollers. The objects are conveyed through the gap between the rollers of the pairs of rollers in such a way that they rest on the lower rollers in each case, while the upper roller in each case rests on the objects. The size of the gap between the rollers of the pairs of rollers can be modified in a defined manner by a special device. The upper rollers in each case of the pairs can therefore be raised or lowered. At the same time, the upper rollers retain a degree of freedom in a vertical direction which enables them to move freely, to a certain extent, upwards and downwards in addition to being raised by the aforementioned device. Account is taken of the "weft" thickness of the objects to be treated by means of the raising device; "fine adjustment" of the nip is then carried out automatically owing to the aforementioned degree of freedom of the upper rollers in each case (Figure 1). <IMAGE>

Title: Apparatus for adjusting the doffing disc on machines for covering doll's heads with hair
Inventor: HALBOTH UWE
IPC: D05C15/02
Filed: 1989-03-04
Abstract: The production of doll's hairstyles with different hair lengths in one operation necessitates a change on the doffing disc of the hair-covering machine by exchange or adjustment. By means of a mechanically actuated adjusting system consisting of a driving disc with bolt, doffing disc and adjusting device, when the hair length is changed the doffing disc is rotated on the machine flange through a predetermined angle as a result of the actuation of an unlocking and locking device and the thread cut-off knife is fed to the changed cutting point. The change in the position of the needle passage point fixed relative to the machine in relation to the slot end drawing out the thread brings about the change in the hair length. By the use of the apparatus, preferably doll's hairstyles with two hair lengths can be produced in one operation, with an only brief interruption for actuating the adjusting device, without a conversion of the hair-covering machine. <IMAGE>
