Abstract: The invention is based on a unit for a vehicle brake system, having a housing block into which magnet valves and optionally other components to be interconnected electrically are built in. The magnet valves are covered by a housing cap, which has externally accessible plug connectors for the magnet valves. To protect the plug connectors against splashing water and dirt when the unit is mounted near the wheel, at least one cover provided, which together with the housing cap forms cable leadthroughs for cables that are connected electrically to the plug connectors.

Abstract: A vacuum cleaner with a steam generator and a source of water under pressure has a suction hose connecting the suction head with the turbine and a dirt collector. Steam and pressurized water lines extend along the hose and the steam line runs to an orifice strip in a sole plate of the head while the spray nozzles are provided in a slot between a pair of brushes. The suction nozzle opens at a slot in the sole plate and sealing strips are provided along the longitudinal sides of the suction nozzle and the steam nozzle strip.

Abstract: An electrical device for a motor vehicle comprises a housing, a printed board carrying an electric circuit and arranged in the housing, the housing being provided with a plurality of webs for abutting the printed board and an elastic element by which the printed board is pressed on the webs.

Abstract: In accordance with a method for assembly and testing the insulation of power components for electronic switching and control devices, particularly for motor vehicles, the power components are fastened to a heat sink so as to be thermally conducting and electrically insulated and are connected together with additional component elements on a printed circuit board and with a circuit ground. In order to protect voltage-sensitive component elements on the printed circuit board, the heat sink is first fastened to the printed circuit board without potential and then the insulation between the heat sink and power component is tested by applying high voltage between the heat sink and power component, and the heat sink is finally electrically connected with the circuit ground.

Abstract: An electrical switching and control device, particularly for motor vehicles has a housing a printed circuit board, a plurality of electronic power components arranged in the housing and having leads soldered with the printed circuit board, another component element carried by the printed circuit board and connected with the latter, a heat sink carrying the power components and mechanically connected with the printed circuit board and also receiving heat generated in the power components and guiding it outwards, a plug-in strip arranged at the front side of the housing and soldered at its rear end with the printed circuit board, the plug-in strip being lockable at the printed circuit board, a frame formed so that the heat sink grasps the plug-in strip by the frame and is securely connected with the printed circuit board, a front panel placed on the plug-in strip with interposition of a seal and screwed together with the frame of the heat sink, the housing and having a front housing opening which is tightly clo

Abstract: A housing for an electronic circuit, in particular for an electronic control circuit of a motor vehicle internal combustion engine has a circuit accommodation area, a connection area, a distribution area, and a connection device for a separable electrical connection of information and supply leads. The housing has two housing parts which are separable from one another and include a first housing part having accommodating area and a second housing part having the connection area for the connection device and having the distribution area. A dividing part separates the connection area and the distribution area. Contact connections for the connection device are provided on the dividing part. The first housing part has a base wall which in a closed condition of the housing closes the second housing part.

Abstract: In known separators, some of the solids trapped in the trapping chutes may be prevented from being discharged at the wall due to by-pass currents at the lower end of the trapping chutes. To improve the discharge of the separated dust, the lower end of each trapping chute that is adjacent to the wall is provided with an outlet channel piece extending to the wall and having a slot-like outlet opening resting at the wall and opening downward; and sheet metal deflectors are arranged between the outlet channel pieces of each layer of trapping chutes at a distance from each other and from the wall, which form between them delimit slots for the passage of gas. The separator is preferably used to separate solids from the ascending flue gas in a fluidized bed furnace.

Abstract: A method and apparatus for burning carbonaceous materials in a fluidized bed reactor comprising a bottom region and a top region, and containing a fluidized bed, with the heat of combustion being dissipated at least via wall cooling surfaces, and comprising a recirculation system, including a labyrinth separator for recirculating the separated solids to the bottom region of the fluidized bed reactor. The solids are separated from the rising flow of flue gas by the labyrinth separator, which is disposed directly in the top region of the fluidized bed reactor, and are conveyed in the reactor itself along the wall cooling surfaces and are supplied to the bottom region of the reactor, either freely or in closed or partly or completely open recirculation passages. The main area of application is with a steam generator.

Abstract: A method of continuous production of refined chocolate mass from a non-refined cocoa mass composed of a mixture of components reduced in size to a fineness required for the final mass but still containing undesired aromatic substances and moisture and being processed into a low fat, friable or pulverized chocolate mass, is mixed in a plasticator with a preheated air stream which is admitted in the same feeding direction, simultaneously externally heated for a time interval between 5 and 8 minutes while being intensively mixed by shearing stresses until the mass becomes plasticized; thereupon the fluidity of the mass is increased by an emulsifier, then the entrained gas is separated from the mass, the latter is weighed and supplemented according to a final recipe by additional fat content, and the final mass is collected in a container and subjected to an additional homogenizing treatment and in a cooled condition is forwarded for the final processing.

Abstract: A method of and apparatus for providing coal dust to a reaction chamber, especially in the process of producing low-sulfur coke dust and gas by gas extraction and partial gasification of coal dust in a reaction chamber for partially combusting coal dust. Coal dust and a first stream of combustion gas are combined and passed through a central conduit to a reaction chamber. A second stream of combustion gas can be selectively subjected to swirling motion and can be combined with the stream emanating from the central conduit. The degree of swirl of the first stream and the second stream of combustion gas is used to control distribution of the gas-solids mixture in the reaction chamber and to control the path of the gas-solids mixture leading into the wall of the reaction chamber.
