Title: Process for producing a foam body
Inventor: KUHLMANN WERNER
IPC: B29C44/04
Filed: 1985-04-03
Abstract: The invention relates to a process for producing a foam body having two foam layers of different density. In order to improve the ease of production, to reduce the weight and increase the strength of a two-layer foam body of this kind, according to the invention, before the foaming of the two plastics which form the foam layers, a coupling layer is introduced into the production mould for the foam body, which coupling layer is arranged so as to be movable with respect to the production mould and separates the region of the first foam from that of the second. The foaming of the region with low foam density is carried out before the foaming of the region with high foam density.

Title: Control circuit for a radiator fan in a motor vehicle
Inventor: RIPPEL WALTER
IPC: H02P7/08
Filed: 1985-12-06
Abstract: The invention relates to a control circuit for a radiator fan in a motor vehicle, having a switchable electric motor and having at least one ballast resistor, which can be connected via a changeover switch, for changing the motor rotation speed. According to the invention, the heating wires (10) of a rear window pane (9) (which can be heated) of the motor vehicle are used as the ballast resistor. As a result of the dual function (carried out in this way) of the rear window pane as a heating element and as a ballast resistor for the fan motor (11), there is no need for a separate ballast resistor, as a result of which space, weight and, overall, costs are saved. <IMAGE>

Title: Process for cleaning waste gases, flue gases and combustion gases
Inventor: BOGUSLAWSKI ZBIGNIEW DR
IPC: B01D53/34
Filed: 1985-12-10
Abstract: Process for cleaning toxic and carcinogenic impurities and hydrogen halides from waste gases, flue gases and combustion gases from, for example, domestic heating systems, power stations and waste incineration plant, internal combustion engines or similar firing systems, using an adsorbent in which the gas is cooled to a temperature lying within the range of the dew point temperature for the water vapour contained in the flue gas and, after commencement of the droplet condensation, while maintaining a working temperature within the range of the saturation limit for water vapour, is led through or over the adsorbent. In this process the gas is cooled to a working temperature lying between 10 DEG  below and 25 DEG  above the dew point temperature. In order to remove the heavy metals or heavy metal oxides, pellets with high porosity are used which have been produced using metal oxides, in particular alkali metal oxides and/or alkaline earth metal oxides and iron oxide and, if appropriate, manganese dioxide, by mixing lime and quartz sand with a grading curve of below 0.3 mm in equal, at least 10 % by weight, [sic] subsequent addition of the chemically or catalytically or quasi-catalytically active materials together with an amount of water sufficient for their complete hydration, and subsequent, in each case multi-stage, pelletisation and thermal treatment at temperatures up to 500 DEG C.

Title: Process and apparatus for centrifugal grinding
Inventor: TODOROV NEDELTSCHO HRISTOV
IPC: B24B31/104
Filed: 1985-12-31
Abstract: In the process for centrifual grinding, an abrasive medium of high kinetic energy is volumetrically compressed by two mutually perpendicular centrifugal forces. The workpieces on which grinding is performed are immersed in the abrasive medium by one of the centrifugal forces and, partially hindered by the friction with the said medium, are turned. The apparatus comprises a base plate (1), on which there is fitted a bearing housing (2), in which there is mounted a spindle with a belt pulley (3), which is driven by a driving belt pulley which is seated on an electric motor (29) fastened on the base plate (1). The workpieces (21) are fitted on arbors (20), which are mounted in bushings (19), which are fastened on a disc (18). The entire construction is surrounded by an outer housing (23). Seated on the spindle with the belt pulley (3) is a column (4), on which there are fastened horizontal columns (9), at each of the ends of which there is arranged an immovable rotor (11), which is surrounded by a stator (12) mounted on the horizontal column (9). Attached on this stator (12) is a working drum (13), fed with an abrasive mixture (15). The disc (18), which bears the workpieces (21), is attached in an axially movable manner on the horizontal column (9), on which there acts a spring (17), which bears with its other end on a bowl (16) rigidly fastened on the horizontal column (9). <IMAGE>
Patent DE-3603886-A1 (DE)
Title: Heat exchanger for heating flowing gases or liquids
Inventor: MEHLITZ DIETER DIPL ING
IPC: F16L53/37
Filed: 1986-02-07
Abstract: The invention relates to a heat exchanger for heating flowing gases or liquids. The medium which is to be heated is passed through a tube (fluid tube) which preferably consists of corrosion-resistant and acid-resistant steel (stainless steel) and which (while at the same time being used as a heat resistor) is electrically heated by a suitable electrical power supply. If a plurality of groups of electrical connections are provided along the fluid tube, the current densities and hence the fluid heating can be varied in specific tube sections. In this case, separate electrical power supplies can also be provided for individual tube sections. Furthermore, temperature sensors can be arranged along the tube, which temperature sensors supply the signals which are required for temperature regulators which are preferably integrated into one or more electrical power supplies.
Patent DE-3608954-A1 (DE)
Title: Shaft seal
Inventor: LIETHEN WILHELM
IPC: F16J15/3244
Filed: 1986-03-18
Abstract: In a shaft seal for sealing off rotating shafts, the protective lip arranged in front of the sealing lip on the air side has areas in which it exerts a relatively low radial pressure and areas in which it exerts a relatively high radial pressure on the shaft so that, in motor-driven operation, when the shaft rotates those areas of the protective lip which exert a higher radial force are subject to a higher frictional force. These areas are subject to compression in operation and, accordingly, the adjacent areas of the protective lip, in which the radial contact pressure is lower, rise from the shaft. While the protective lip provides optimum protection against the ingress of dirt particles and moisture, this simultaneously avoids the formation of a vacuum in the space between the sealing lip and the protective lip, with its disadvantageous consequences for the wear on the lip contact surfaces. <IMAGE>

Title: Air drier for compressed-air systems
Inventor: UNGER HANS
IPC: B60T17/00
Filed: 1986-10-24
Abstract: The air drier has an intake chamber (3) which is pneumatically connected on one side to an outlet valve apparatus (24) and on the other side to a drier cartridge (8). Between the intake chamber (3) and the drier cartridge (8) is arranged an apparatus designed, for example, as a disc (18), which keeps pressure pulses, produced by the compressor, in the intake chamber (3) away from the drier cartridge (8) and the chamber receiving this in a housing pot (6). As a result, the air drier is prevented from being stimulated to deliver knocking noises by the pressure pulses. The venting of the compressor by the outlet valve apparatus (24) during idling phases is not prevented. <IMAGE>
