  • Patent number: 5336390
    Abstract: An electrochemical gas sensor for detecting gaseous components in the environment has a diffusion membrane, a measuring electrode, a counterelectrode, and, if desired, a reference electrode, pressed together in a disk stack, which are accommodated in a pot-shaped cover, which in turn is beaded around the sealing edge (6) of a housing pot (1). A compression spring (21) in the housing pot (1) presses a wick disk (20) against the measuring electrode (12), so that a constant and pressurized, intimate and sealed positioning of the disk stack is guaranteed. It is achieved as a result that no additional contact leads from the electrodes to the outer space of the sensor to the measuring and evaluating unit are needed, so that leakage-free sealing of the sensor to the outside is possible, and that a constantly stable, reproducible measured signal is obtained because of the defined and narrow electrolyte film on the surface of the measuring electrode.

  • Patent number: 4900101
    Abstract: A brake system with slip control is disclosed including a master cylinder to which wheel brakes are connected through controllable main valves. An auxiliary-pressure supply system including a hydraulic pump, a regulating and pressure-monitoring valve and a pressure-compensating and pressure-fluid supply reservoir is connected to the wheel brakes through electromagnetically actuatable inlet and outlet valves. The outlet valves are normally closed in their inactive condition with each one pair of wheel brakes communicating directly with one inlet valve and one outlet valve. Wheel sensors and an electronic circuitry determine the wheel rotational behavior and generate electric braking-pressure control signals for operating the inlet and outlet valves. The inlet valves are closed in their inactive condition and are switched to open upon actuation and have their inlet side directly connected with the auxiliary-pressure supply system and their outlet side directly connected with the main valves.
