Title: Process and device for extracting oil or polychlorinated biphenyl from impregnated electrical components by means of a solvent, and for distillation of the solvent
Inventor: OESCH GUSTAV
IPC: H01F27/14
Filed: 1987-05-07
Abstract: In a heating-up phase, a solvent evaporates in an evaporator (2) located in an autoclave (1), and the solvent vapour condenses on the components, heats the latter and penetrates the electrical insulation in order to dissolve out the oil or polychlorinated biphenyl (PCB). In the heating-up phase, several intermediate reductions in pressure are carried out in the autoclave (1) and, during each intermediate pressure reduction, the solvent from the oil/solvent mixture or PCB/solvent mixture is distilled directly out of the autoclave (1), the solvent feed being isolated each time and the mixture being circulated via a circulation line (d-9-d-10-d-e). After the end of each intermediate pressure reduction, the pure oil or polychlorinated biphenyl present in the condensate container (9) is pumped out via a condensate discharge line (d) with an interposed conveying pump (10) and via a connecting line (g) into a stock tank (13). <IMAGE>

Title: Crusher conveyor having pre-separation of fines and shifting device
Inventor: KROHM REINHOLD
IPC: E21F13/08
Filed: 1987-06-20
Abstract: A crusher conveyor comprising two conveyors, usually chain scraper conveyors, arranged one above the other, in which crusher conveyor a crushing device is also integrated, is advanced as a unit since it is reinforced by appropriately strong side walls and transverse covers, which simultaneously surround the two conveyors, so that dust encapsulation is provided. Running rollers corresponding to a shifting device are arranged on both sides of the housing which is formed by the stable side walls and the transverse covers and is part of the two conveyors. These running rollers preferably roll on a trolley track so that substantially reduced tensile forces occur. By this means, it is possible, using a relatively simple shifting device in the form of an advancing cylinder, to advance the entire unit in a manner corresponding to the progress of mining without interruption of the operation being necessary. <IMAGE>

Patent DE-3725923-A1 (DE)
Title: Converter system having an intermediate-circuit DC voltage which is obtained by means of a rectifier
Inventor: CIESSOW GUENTER
IPC: H02M7/487
Filed: 1987-07-31
Abstract: The invention relates to a converter system, especially for controlling long-stator, three-phase linear motors of electric railways, having an intermediate-circuit DC voltage which is obtained by means of a rectifier, from which invertors are supplied which produce a variable-voltage and variable-frequency multi-phase supply, voltage control being carried out by pulsed operation of the invertor at low motor frequencies, and by summation of individual voltage elements at relatively high motor frequencies. In order to avoid the previously normal gaps in the propulsion force and braking force without using output transformers, making available an output voltage which is low in harmonics and ensuring an adequate motor voltage during starting by increasing the substation output voltage, it is proposed that operation without any transformers be carried out at all frequencies via a multi-point invertor having high-power semiconductors (16) which can be cut off, during which operation a plurality of DC voltage elements (+/M; M/-) can be connected in series on the input side and during which a voltage adjustment, especially in the range of high motor frequencies, can be achieved by variation of the individual intermediate-circuit voltages via the rectifiers (14, 14'), the invertor (16) being operated predominantly at full load, with the same wave form of the output voltage. <IMAGE>

Title: Recyclable paper, and process for the production and recycling thereof
Inventor: RATHJEN AXEL DIPL ING
IPC: D21H19/38
Filed: 1987-08-26
Abstract: The invention proposes a recyclable paper in which a fine-grained top layer absorbs the majority of the printing ink pigments. In order to recycle a paper of this type, there is no need, in contrast to conventional recycling of used paper, to dissolve the pigments of the paper constituents. Instead, the size and type of top layer particles should be selected during production of the recyclable paper in such a way that these particles can be deposited as completely as possible from the paper suspension together with the adhering pigments in as possible a separation process as possible. In the proposed process, virtually all deinking steps are superfluous. The valuable fibrous paper constituents are protected and can be employed in a larger proportion than hitherto in the production of relatively high-quality papers.

Title: Apparatus for producing prefabricated mats from mosaic, ceramic tiles or glass panes
Inventor: RIPPLINGER ARMIN
IPC: E04F13/14
Filed: 1988-01-22
Abstract: Known apparatuses for producing prefabricated mats from mosaic, ceramic tiles or glass panes, whose reverse is bonded to a net or paper, operate with gridded plates which are conveyed, arranged in sequence, on flat conveyor belts. The production sequence is cumbersome and expensive and requires a large number of gridded plates and, because of the unusual length of the conveyor belts, large workshops. The new apparatus consists of a conveyor belt which has, over its entire length and width, self-centring fields to receive mosaic, ceramic tiles or glass panes, circulates in a similar manner to conventional band-type conveyor belts and transports the setting materials located on the conveyor belt past stock rollers with nets or paper, so that the latter can automatically be temporarily bonded to form individual mats and then dried.

Title: Abdominal muscle training apparatus
Inventor: MUELLER HELMUT
IPC: A63B23/02
Filed: 1988-04-15
Abstract: The training apparatus trains the straight and transverse abdominal muscles. An object of the invention is to design such an apparatus so that the flexile muscles of the legs and hips are relieved of stress so that isolated tensioning of the abdominal muscles is permitted without involvement of the flexile muscles of the legs and hips, and hence the disadvantages of the state of the art do not arise. According to the invention, its bearing surface (7) for the upper body and bearing surface (8) for the calves is so arranged that the thighs preferably form a right angle to the upper body and take a relaxed position with the legs. They are thus not used as counter-supports for the upper body. The apparatus can, as shown in Figure 1, be used in conjunction with wall bars, a door-frame corner or a frame specifically constructed for the purpose. The oblique position can be individually set. <IMAGE>

Title: Process and apparatus for producing plastic pallets
IPC: B29C51/36
Filed: 1988-05-03
Abstract: A process and apparatus serve for producing pallets. A sheet (20) of thermoplastic material is heated, then introduced into the soft state between two complimentary mould parts (40, 70) of a two-part mould (30, 31) and brought into the desired pallet shape there by closing the mould (30, 31).

To be able to produce pallets with dimensionally stable inner and outer surfaces and good reproducibility, a positive pressure is additionally established, at least in certain regions, on a third forming area (55) of the other mould part (40) lying opposite the first moulding area (76) (Fig 2.) <IMAGE>
Patent DE-3818010-A1 (DE)
Title: Process and apparatus for generating smoking smoke
Inventor: SCHMIDT EDWIN P
IPC: A23B4/052
Filed: 1988-05-27
Abstract: In known processes, the pyrolysis of the smoking material proceeds on electrically heated pyrolysis plates or in a smouldering funnel, on a friction wheel or by super heated steam, with feed of fresh air to the pyrolysis position for the smouldering effect and for smoke transport. Despite complicated fresh air metering, exothermic reactions occur in the course of this at the pyrolysis temperature which should not exceed 400@C. However, this occurs involuntarily with each air draft. The apparatuses are equipped with complex expensive equipment. The smoking smoke contains, increased as a result, pollutants, and ash dust and soot particles. In the process according to the invention, the pyrolysis of the smoking material proceeds in a vessel by means of direct microwave effect without an air draft coming into contact with the pyrolysis position. Without thermostatic control, the pyrolysis temperature is constantly below 400@C. Smoke transport proceeds in a self-induced manner. The low-pollutant smoking smoke free from contamination is used for the preservation and flavouring of foods such as meat products, sausage products or fish products.

Title: Device for particle separation and odour removal from the fresh air passed into the interior of a motor vehicle
Inventor: KERSTNER RALPH
IPC: B60H3/06
Filed: 1988-07-19
Abstract: Dust filters in which the air is passed through the filter material become clogged in a short time when used in a motor vehicle. Another filter construction which does not have this disadvantage loses a large part of its efficiency at low air velocities. In order to avoid the disadvantages of previous filter constructions and, moreover, to achieve a further increase in the air purification in a motor vehicle, a fine filter (18) which contains filter plates arranged one after the other in a manner known per se, which filter plates are coated on the air intake side with a glycerol-impregnated plastic foam, is combined with a motor vehicle air conditioning unit in such a way that the fine filter is connected to the air intake connection branch (2) of the associated air conditioning housing (1). As a result of the improvement according to the invention of the fine filter used, defect-free filter action results even at low air velocities. The purification action on the fresh air conducted into the interior of a motor vehicle is so thorough that odour pollutions are eliminated and, even at times of high pollen count, persons who suffer from strong pollen allergy are free from discomfort in the vehicle. <IMAGE>
