  • Valve control unit
    Patent number: 6863254
    Abstract: 2.1. Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools. 2.2. In order to reduce the assembly effort required as well as the play of the valve domes on the inside of the spool, yoke arrangements are mounted externally on the housing. 2.3. Such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.

  • Valve control device
    Publication number: 20020056820
    Abstract: 2.1. Existing valve control devices are set up in housings that feature a cover and a frame in which the valve spools are embedded. Between the cover and the frame, there is the circuit carrier with the electronic components. With the new valve control device, there is no longer to be any need for a housing, and the manufacturing process is to be simplified.

  • Housing for installation in motor vehicles
    Patent number: 5075822
    Abstract: The invention relates to a housing for installation in motor vehicles to hold electronic components arranged on a PCB. In accordance with the invention, the housing comprises a trough-shaped housing section and a metal lid. In addition, several heat sinks are arranged on the PCB, with the PCB being firmly connected exclusively to these heat sinks. Here, the heat sinks are designed such that they are in direct contact with both the housing section and the metal lid.

  • Arrangement for applying adhesive medium, particularly for leather and shoe articles
    Patent number: 4651906
    Abstract: An arrangement for applying an adhesive medium, particularly for leather and shoe articles, has an adhesive medium applying nozzle and a nozzle needle member arranged to close and to open the nozzle. A driver connects one end of the nozzle needle member with a driving unit which includes at least two selectively actuatable driving devices formed with individually adjustable displacement elements so that they move the nozzle needle member selectively over different adjustable strokes.

  • Connector for printed circuit boards
    Patent number: 4436362
    Abstract: A connecting plug for printed circuit boards has a receiving part with a front cross bar having rectangular openings therein surrounded by insertion bevels and corresponding to the necessary contact count. A multiple contact strip containing contacts snaps into the receiving part. Contact insertion and a decrease in assembly is thereby facilitated. The connecting plug is suitable, in particular, for use in devices of data systems.
