Patent DE-3732013-A1 (DE)
Title: Process for binding oil of an oil/water suspension
Inventor: BRENNER ALWIN
IPC: E02B15/04
Filed: 1987-09-23
Abstract: The invention relates to a process and an apparatus for binding oil of an oil/water suspension, i.e. for purifying water contaminated by oil, by means of a chemical binder. In order to accelerate and intensify the reaction between binder and oil, the water to be purified is stirred, swirled or otherwise brought into agitation with appropriate means. Since the water can also be polluted by oil beneath the surface, the apparatus for carrying out the process is designed in such a way that the water is collected down to a defined depth. The vortexing of the water can be achieved by the apparatus being funnel-shaped; at the narrow end of the funnel an impeller wheel can further be provided to promote this vortexing. <IMAGE>

Title: Screen printing method for printing on webs of material with coloured images, drawings and the like
Inventor: UYARGIL MEHMET
IPC: D06P5/00
Filed: 1987-09-24
Abstract: A screen printing method for printing on webs of material with coloured images, drawings, photographs and the like is described, wherein the web of material is fixed on a table top by means of an easily detachable adhesive, a first screen printing stencil is then aligned by means of stops located at the edge of the table, and a first printing ink is applied to the web of material through the screen of the screen printing stencil by means of a squeegee or the like, whereupon a further screen printing stencil is aligned at the same place and, correspondingly, a second printing ink is applied to the web of material, then correspondingly a third ink with a third screen printing stencil and, if appropriate, a fourth (or further) ink, which is preferably a black ink, the printing inks being successively applied, according to the invention, to the web of material in such a consistency and at such a time interval that the ink already applied to the web of material still contains so much solvent or damping medium that the newly applied ink mixes with the already applied ink due to viscous material mixing or due to pigment diffusion in the pigment carrier.

Title: Umbrella holder for automobiles
Inventor: DINKLER INGEBORG
IPC: B60R7/12
Filed: 1987-09-30
Abstract: A holder composed of an upper ring and a lower container which may be separate or integrally connected to one another are used to accommodate one or more umbrellas in the car. The parts can be fastened at an appropriate point in the car by means of adhesives, screws, etc. The ring and the container have a hinged joint to ensure that the parts do not get in the way when not in use. This is the exemplary embodiment. The concept of the patent covers all conceivable embodiments of umbrella holders in automobiles, however.
Patent DE-3733688-A1 (DE)
Title: Insert body for gravity separators
Inventor: ZWITTNIG LEOPOLD DIPL ING
IPC: B01D17/04
Filed: 1987-10-05
Abstract: An insert for gravity separators, especially oil separators (1), has slowing-down surfaces for the liquid flow in the separator and thus enables the small oil droplets polluting the water to combine into larger oil droplets in the water. This results in increased bouyancy of the droplets and an increase in the efficiency of the separator. The insert is designed as a liquid-permeable package (8, 9, 10) which, for example, is shrouded in a net-like manner or held together by internal links, and contains surface elements (12) which bound interspaces for the water contaminated with oil to flow through. The packages can be moved up and down via ropes (13) in the separator. The surface elements (12) used can be plastic wastes, especially containers from domestic waste, preferably cut up. <IMAGE>
Patent DE-3743752-A1 (DE)
Inventor: LECHERT HANS PROF DR
IPC: C10G1/00
Filed: 1987-12-23
Abstract: A liquid fraction and a gas fraction produced during the reprocessing of waste material containing CH compounds by pyrolysis, have a mass ratio approximately equal to 1. Since the liquid fraction is more suitable for further processing than the gas fraction, there is an incentive to augment the liquid fraction at the expense of the gas fraction. In order to achieve this object, the pyrolysis gas is cooled until the benzene and the higher-boiling gaseous constituents of the pyrolysis gas pass into the liquid phase, so that a benzene-containing liquid fraction is produced. A gas mixture containing benzene and toluene is stripped out of the benzene-containing liquid fraction, passed together with the gas fraction at a temperature of 300 DEG  to 450 DEG  C. over a zeolitic catalyst and then separated by cooling into both a fraction which is liquid at atmospheric pressure and a residual gas fraction. As a result, the proportion of the liquid fraction is substantially increased and the economics of the process are substantially improved.

Title: Device for vacuuming dust at the drying cylinder of a paper machine
Inventor: MASUCH JUERGEN DR ING
IPC: D21H25/00
Filed: 1988-01-13
Abstract: There is described a device for vacuuming dust at the drying cylinder of a paper machine, along the peripheral surface of which the paper web runs past a creping doctor, on which and from which the paper web is pulled off, and in which a cleaning doctor is arranged behind the creping doctor in the direction of rotation.

Title: Switching device for an electrical service unit, especially a plug socket having two disconnectable poles
Inventor: EICHHOFF KARL-HEINZ
IPC: H01R13/70
Filed: 1988-01-30
Abstract: The invention relates to a switching device for an electrical service unit, especially for a plug socket having two disconnectable poles and with a child-protection device in accordance with the British Standard, having a switching rocker which is mounted such that it can pivot, and having an illumination source on the housing upper part, as well as having two contact rockers which are each supported on blades, in the housing lower part, on which spring plungers act during operation. In the case of known plug sockets of this type, the contact rockers for disconnection of the plug socket are normally located side by side, so that a relatively large area on the base of the plug socket needs to be allowed for this arrangement. This leads to voluminous equipment designs which make oversize service boxes necessary. The invention solves the problem by the contact rockers being arranged one behind the other in the tilting direction and by a switching slide being provided for their operation, which switching slide is operatively connected to the switching rocker and whose underneath carries spring plungers which are directed towards the contact rockers and by means of which it causes the contact rockers to tilt over into the respectively other switching position in the event of a sliding movement, provided an operating pressure is exerted on the switching rocker.

Title: Degassing scrap plastics for pyrolysis - comprises heating, dropping down feed pipe to revolving drum forming thin layer on surface, volatile gases are drawn off under vacuum
Inventor: KITZMANN EWALD DIPL ING
IPC: B01D19/00
Filed: 1989-07-29
Abstract: In a process for degassing particularly viscous liqs.  such as scrap plastic melts, a revolving drum is partly filled with the material so as to form a coating film on the revolving surface, from which film the gases readily escape, and the time provided for such escape is regulated by adjusting the speed of rotation of the drum. Scrap plastic material drops down the pipe (14) into the space (17) between the revolving drum (26) and a concentric outer cover (16). The material is electrically heated and its non-fusible components fall further down into the hopper (13) and below (15) for removal. The polymer material is kept to a particular level in the annular space by a baffle (28). Vacuum is applied to the top outlet (22) to draw off volatiles, and the speed of revolution of the drum (26) is adjustable so that the material scraped by the plate (30) is quite free from volatiles. ADVANTAGE - The process is particularly useful in getting rid of e.g. HCl, HCN, CO, CO2 and moisture etc. from scrap which is to be subjected to pyrolysis.

Filed: 1989-10-24
Abstract: A process is disclosed for storing colour television signals in a digital memory. In known devices, the colour signal is first demodulated before being stored in a memory, then modulated again when it is read out of the memory, at great expense in circuitry. According to the invention, the colour vector is stored together with the burst, which serves as a reference frequency for a phase regulating circuit arranged after the memory. The reference frequency is compared with the burst of the colour signal of the main image. The invention is useful for reproducing images within images in coulour television receiver sets.
