Title: Process and appts. to wash contaminants, esp. hydrocarbon(s) from grains separates coarse fraction - and washes within separate circuit using recycled water to reduce contaminant concentration
Inventor: BARTMANN ALFRED ING
IPC: B09C1/02
Filed: 1993-08-04
Abstract: A process and appts. are claimed to continually wash contaminated granular substances, the novelty is that the coarse fraction of grains in the range 10 to 80 mm are separated from the other fractions and washed using water which has previously been used for washing and subsequently treated and cleaned.

Coarse grains are passed (5) via a sieve (7) with a water inlet (10) and a coarse fraction outlet (11). ADVANTAGE - The process and assembly facilitate a continuous process esp. for the removal of hydrocarbon impurities within a closed system yet minimising concentrations of contaminated substances, using relatively simple equipment.

Patent DE-4332498-A1 (DE)
Title: Method and apparatus for printing individual flat objects
Inventor: ROHWETTER NORBERT
IPC: B41M1/40
Filed: 1993-09-24
Abstract: The invention relates to a method and an apparatus for printing individual flat objects, e.g. CDs, by means of offset printing. In this process, the surface to be printed on the one hand and the offset impression cylinder, which is to roll along the object to be printed, are adjusted relative to one another to achieve a pressure which is favourable for the transfer of the printing image to the object to be printed in order thus to compensate differences in thickness between the individual objects. Furthermore, provision is made, if required during the adjustment of the impression cylinder and the surface to be printed relative to one another, for the radial position of the transfer surfaces located on the circumference of the impression cylinder to be taken into account. In the event of there being no object in the offset printing station, a substitute object in the form of a web of material can be provided, onto which the printing image intended for the missing object is transferred by the offset impression cylinder. Additionally, it is also possible to adjust the block cylinder relative to the impression cylinder in such a way that adaptation to the radial position of the abovementioned transfer surfaces is possible.

Patent DE-4337064-A1 (DE)
Title: Rotary piston engine
Inventor: DRESLER HELMUT
IPC: F01C1/107
Filed: 1993-10-29
Abstract: The proposal is for a rotary piston engine with a displacement element 12 which has a helical groove 17 and rolls along the internal diameter of a cylinder 2 due to an eccentric fitted on a drive shaft 5. The rotary piston engine furthermore has a helix 11, the external diameter of which always rests on the cylinder 2 and the internal diameter of which forms a seal in every position of the eccentric on the base of the groove of the displacement element 12. Owing to the inclination of the groove 17 in the displacement element 12 and to the movable insertion of the helix 11 into this groove 17, it is possible, when the drive shaft 5 is rotated, for a fluid to be delivered from an inlet chamber a into a delivery chamber b. <IMAGE>

IPC: H01R13/719
Filed: 1993-11-18
Abstract: A plug for gas generators of air bag impact protection systems has current paths formed by sheet metal strips and an inductance coil in one of both interrupted current paths that form two poles. One of the current paths is U-shaped; its branch opposite the counter-current path (4) is interrupted to form two inner poles (1, 2) and acts as a mechanical support for the inductance coil (5) that electrically bridges the interruption, and the other branch (3), located next to the counter-current path (4), forms together with the counter-current path (4) plug pins (6, 7) that extend outwards. The plug pins (6, 7) are formed by bending the T- or fork-shaped ends of the current paths (3, 4). The inductance coil (5) is arranged in a housing and is provided with electric connections that can be directly connected to the inner poles (1, 2). In order to manufacture this plug, a preform is first cut out of a sheet metal web. The poles and current paths are repeated and held away from each other in the preform, then are embedded in a common substrate and the inductance coil (5) is mechanically and electrically connected to its support (1, 2).

Patent DE-4412126-A1 (DE)
Title: Synthetic resin product and method for manufacturing it
Inventor: FUNAHASHI TOSHIKAZU
IPC: H05K3/24
Filed: 1994-04-08
Abstract: Profiled steps and profiled grooves are fashioned on a grating body along stepped profiles. The grating body is subjected to chemical (electroless) plating. Since the grooves have narrow bottom zones, these remain unplated, so that a chemical-plating layer is formed on the entire surface of the grating body with the exception of the said bottom zones. The grating body, which is provided with the chemical-plating layer formed thereon, is then subjected to an electroplating step. A priming plating layer is generated on the chemical-plating layer which is formed on those sections, to which a decorative cladding is to be applied. The chemical-plating layer formed on those sections, on which no decorative cladding is to be produced, is dissolved by means of a predetermined solution. Then a general electroplating layer is provided on the priming plating layer. Thus the chemical- and the electroplating layer are formed only on the sections to be plated. A plating layer which comprises both the chemical- and the electroplating layer is masked with an electroforming mask, and a coating layer is formed on the exposed sections, the edges of the electroforming mask being precisely alignable with the edges of the plating layer. The boundaries between the coating or covering layer and the decorative plating layer can thus be clearly defined.

Patent DE-4416043-A1 (DE)
Title: Installing metal and/or plastic service supply lines in multi-storey building
Inventor: KRUEGEL MEINFRIED
IPC: E04F17/08
Filed: 1994-05-03
Abstract: The wall thickness deviation (DELTAd) of all rooms, storey-to-storey is established. An installation template is established in the topmost storey of the plumb point (P1) for the pipe run (P2) of the individual pipe entries, taking account of the deviations and the shaft size. The drilling with the largest dia. is firstly set as the main bore (13) with a basic tolerance(alpha). An imaginary plumb line from this is dropped on the floor of the underlying storey. The coincidence of plumb and bore marks is tested by the template.The positional deviation is established w.r.t. the top shaft, and with a deviation the imaginary plumb line is shifted. This method is repeated storey-by-storey. The drilling run is always aligned according to the reference point in the topmost storey. The correction is carried out by a correction organ suspended in the bore. A plumb bob (18) with a plumb line (27) is arranged in the middle of the organ. A receiver (28) is provided in the bob (18), in which a laser light source (29) with a current supply is accommodated.

Title: Method for the optical isolation of a laser-beam source and optical isolator, in particular for carrying out the method
Inventor: PALME MARTIN DR
IPC: G02B5/18
Filed: 1994-07-18
Abstract: The invention relates to a method for the optical isolation of a laser-beam source and an optical isolator, in particular for carrying out this method. The inventive method is distinguished by the fact that, as a result of diffraction, the laser beam is subjected to a beam division and energy division and that, after the diffraction, the energy level of an interference beam retroreflected in the direction of the laser-beam source is lower than the energy level of the laser beam. For the incident laser beam, the diffractive optical element(s) exhibit(s) in the direction of the useful beam a higher diffraction effectiveness (efficiency) than for the beam which returns in the direction of the diffractive optical element after a reflection. Optical isolators preferably have a plurality of diffraction gratings in transmission or reflection.
