Patent DE-3143843-A1 (DE)
Title: Method of lifting and applying a tool plate and device for carrying out the method
Inventor: VEIHELMANN TRAUGOTT
IPC: H05K3/46
Filed: 1981-11-05
Abstract: The invention relates to a method and an assembly device for lifting and applying a top tool plate. If the top tool plate (6) is to be lifted from a bottom tool plate (7), the tool plate (6) is first lifted vertically and then turned over. In this way, the insides (8, 9) of the two tool plates (6, 7) become freely accessible. To mount the top tool plate (6) in position, it is first turned over in the opposite direction in such a way that it comes to lie at a slight distance above the bottom tool plate (7). It is then lowered vertically. With the invention, material (14) to be pressed can be inserted between two tool plates (6, 7) without the tool plates (6, 7) having to be moved by hand. This makes the work considerably easier, for example for producing multi-layer printed circuit boards.

Title: Process for producing biogas and apparatus for carrying out the process
Inventor: BORST ADOLF H
IPC: C12M1/107
Filed: 1982-11-22
Abstract: A process for producing biogas from biomass such as animal faeces with added organic components is described, which supplies biogas which, compared with conventionally produced biogas, has a significantly higher specific calorific value. For this purpose, in a first treatment phase bacterial strains are added to the biomass which produce biogas having a relatively high CO2 fraction from the reaction material. This first treatment phase is followed by a second in which bacterial strains are used which are able to produce methane from CO2. The biogas produced in the first treatment phase is offered to the bacteria active in the second treatment phase as nutrient, as it were. In an apparatus suitable for carrying out the process according to the invention, reaction chambers suitable for the individual treatment phases are thermally well insulated from each other and can be heated to the particular reaction temperatures at which the bacteria used for each respective purpose develop most expediently.

Patent DE-3302602-A1 (DE)
Title: Self-emptying centrifuge drum
Inventor: BRUENING PAUL DIPL ING
IPC: B04B1/18
Filed: 1983-01-27
Abstract: The drum consists of the lower portion 1 in which the piston slider 2 moves axially and bears, in its closing position, against the sealing ring 3 in the drum cover 4, thus closing the discharge openings 5 in the lower portion of the drum. To carry out partial emptyings, closing liquid is let out of the closing chamber by alternate actuation of the piston valves 8,9. Since the piston slider always initially sinks to where the channels 7 open into the closing chamber 6, one-sided solids discharge and hence after a few emptyings, dangerous imbalances arise, in the case of centrifuge drums with only one piston valve, or two simultaneously actuated, but unequally working, piston valves. By the alternate actuation of at least two symmetrically arranged piston valves, the one-sided solids build-up in the drum is nipped in the bud. <IMAGE>

Patent DE-3307826-A1 (DE)
Inventor: HAEFELE WALTER
IPC: F02M59/44
Filed: 1983-03-05
Abstract: The fuel injection quantity of a fuel injection apparatus provided with a fuel injection pump is electrically regulated by means of the opening duration of a metering valve. Additionally, a shift in the instant of supply onset controlled in accordance with operating characteristics is attained by means of a change in the return-flow fuel quantity, which is diverted into a refill reservoir and then refilled completely into the pump work chamber by the beginning of the next subsequent injection stroke. Serving as the sole connection between the refill reservoir and a pump work chamber is an overflow conduit, the overflow opening of which, located at the discharge location into the pump work chamber, is opened by two control locations on the pump piston at the end of supply and once again shortly before bottom dead center. The two control locations are embodied by an oblique control edge on the pump piston that determines the end of supply and by a horizontal, end-face control edge, with the horizontal control edge assuring that shortly before bottom dead center any remnant quantity of the return-flow fuel still remaining in the refill reservoir is refilled back into the pump work chamber.

Patent DE-3403219-A1 (DE)
Title: Cycle derailleur gear system with two packets of multiple crown gears connected one behind the other
Inventor: FUETTERER WERNER
IPC: B62M9/12
Filed: 1984-01-31
Abstract: Previously, it was not possible to combine a back-pedalling hub with derailleur gears because the length of chain available or necessary in a derailleur gear system caused far too much back crank play. By means of two multiple crown gears connected one behind the other, the second serving as compensation crown gear, the length of chain is compensated for each gear in such a way that, in the case of braking with a back-pedalling brake, the passage of chain in the upper region is not very large. The small length of chain which is additionally required for sliding over the crown gears is not very large. So that the length of chain is always compensated, the second crown gear is mounted below the hub drive crown gear packet on a lever attached to the axle and the fork blade. This second multiple compensation crown gear which does not have any locking latches is mounted on the lever in the opposite way so that the addition of the respective upper and lower crown gear produces the same number of teeth. As a result, the length of chain is the same in each gear and it is possible to brake with the back-pedalling brake without an excessively large crank play being necessary. The small length of chain which is additionally required for sliding over the chain is compensated by means of a known derailleur/tensioning mechanism. This tensioning mechanism is not loaded during braking, it is raised somewhat and the chain runs virtually freely through the two rollers.
Patent DE-3404052-A1 (DE)
Title: Process for the production of a high temperature-resistant, flexible fibre ceramic article
Inventor: CYRON THEO DIPL ING
IPC: D04H1/54
Filed: 1984-02-06
Abstract: The present invention relates to a process for the production of a high temperature-resistant fibre ceramic article, for example made of Al2O3. In this process, the article is preformed from ceramic fibre material, preferably dry-pressed and introduced into a pressure chamber. The pressure chamber is subsequently filled with a mixture of a combustible gas and oxygen, and the gas mixture is ignited. The gas mixture (for example detonating gas) which has flowed into the cavities, of various sizes, in accordance with the prepressing pressure generates temperatures of above 3500 DEG C for a fraction of a second during the explosion, these temperatures being sufficient to melt the low-thermal-conductivity ceramic fibres at the surface and to weld them to one another at the points of contact. A very high strength of the fibre structure is thereby achieved while the fibre elasticity is simultaneously retained.
