Patent DE-3904652-A1 (DE)
Inventor: BEHRENS WOLFGANG
IPC: C02F1/28
Filed: 1989-02-16
Abstract: To reduce the nitrate content in groundwater, drinking water or surface water, bark mulch (12) is introduced into the ground (10). To achieve a large surface area, bark mulch is used in a particle size of smaller than 20 mm, and it is further proposed that bark mulch is mixed with granulated clay and lava. The bark mulch, or bark mulch mixture, results in nitrogen being bound and stored in the growth-free period (autumn to winter), and with the beginning of the vegetation time (spring), the nitrogen required by the plants at this time is again set free. <IMAGE>
Patent DE-3905370-A1 (DE)
Title: Composite film
Inventor: BOHN PETER
IPC: B65D65/40
Filed: 1989-02-22
Abstract: A composite film (1a) serves for producing containers, in particular tubes. It has outer layers (2, 10) and a supporting layer (4) of stretched polyester located in between them. The outer layers of polyester permit unproblematical bonding to parts of the container which likewise consist of polyester. A metal layer (5) adjoining on the side of the supporting or intermediate layer facing away from the content of the container ensures together with the intermediate layer of stretched polyester that there is good gas tightness and aroma impermeability. The intermediate layer (4) of stretched polyester in this case prevents aggressive product in the container being able to diffuse through to the metal layer. If the composite film is used for producing tubes, like materials, namely amorphous polyester, lie on top of each other in the seam overlap region of the longitudinal seam of the tube, so that good sealing can be obtained during bonding (Fig. 2). <IMAGE>

Patent DE-3906166-A1 (DE)
Title: Electrical power supply unit
Inventor: SIGLOCH RAINER DIPL ING
IPC: H05K5/02
Filed: 1989-02-28
Abstract: In the case of known electrical power supply units for telecommunications devices, the transformer and the inductor are plugged onto the printed circuit board as separate components and are soldered to it. In this case, the transformer cannot be connected to the inductor via the printed circuit board, and the two components must be connected to one another by means of free wiring. This makes the production of the unit costly and, in addition, the electromagnetic compatibility is poor, because of the free wiring. The problem which is to be solved comprises the simplification of the production of the electrical power supply unit and improvement of the electromagnetic compatibility. The basic idea of the invention is to accommodate the transformer 40, the inductor coil 32 and the leads 42 connecting them together in a common housing 44 and to pot this assembly using a plastic compound 45, all the external connecting pins 2 to 27 being passed out of one surface 46 of the housing 44. In this way, the number of components and the number of exits from the housing are reduced. In addition, the wiring of the electrical power supply unit is simplified. <IMAGE>
Patent DE-3909411-A1 (DE)
Title: Tandem steadyrest
Inventor: WILL HANS-WERNER
IPC: B23Q1/76
Filed: 1989-03-22
Abstract: In a tandem steadyrest, the workpiece is supported by two supporting beams (4) which are each supported in a slightly vertically movable manner on an adjusting device (3) of a basic body (2). The supporting beams (4) can thereby be moved without load up to the workpiece or away from it during the machining operation. The hydrostatic pressurising of the supporting shells (5, 6, 7) of the supporting beam (4) is effected only when the supporting shells (5, 6, 7) are at the correct distance from the workpiece (8) and they are to support the workpiece (8) or compensate for the deflection. <IMAGE>
Patent DE-3918121-A1 (DE)
Inventor: REINARTZ JOHANN OTTO
IPC: A01K1/01
Filed: 1989-06-02
Abstract: PCT No. PCT/DE90/00120 Sec. 371 Date Mar. 29, 1991 Sec. 102(e) Date Mar. 29, 1991 PCT Filed Feb. 22, 1990 PCT Pub. No. WO90/14759 PCT Pub. Date Dec. 13, 1990.The advantage of this toilet for cats relative to conventional models consists of the fact that the toilet automatically cleans itself after each use and is again automatically supplied with fresh cat litter. Annoying odors are extensively eliminated by that the used cat litter is immediately removed into a separately mounted, air tight waste container equipped with a replaceable bag, by a slide. This satisfies both the hygienic requirements of contemporary household pet maintenance and the cleanliness needs of cats. The probelm is resolved by that a slide is located in the cat toilet facility, which moves the used cat litter into an automatically opening and closing waste container and that subsequently fresh cat litter is distributed over the bottom by an automatic refill device. To prevent access to the toilet facility during the cleaning process, the inlet is closed by a sliding door.

Title: Metallising plastic conductor plates coated with conductive layer - by applying electric charge between soln. and plates to enable shorter process time
Inventor: GRAPENTIN HANS-JOACHIM
IPC: H05K3/00
Filed: 1989-06-30
Abstract: Chemically metallising a plastic substrate whose surface has been already partially coated with or electrically conductive layer consists of applying an electrical potential to the already partially coated layer just before or just as the substrate is wetted by the metallising soln. The other pole of the E potential charge is the soln itself. USE/ADVANTAGE - Esp for metallising printed circuits having through holes. By using the potential charge the process time in the bath is reduced and thereby the length of the appts is reduced.
