    摘要： A method and a circuit arrangement for photographic cameras for automatic determination of the exposure value by means of electrical signals obtained from integrated and selective brightness measurements of the object to be exposed. A difference value is formed, for the exposure control, in a manner which is known per se, from the comparison of an electrical signal value derived from the selective metering with an electrical signal value generated from the integrated metering. A correction value is determined from the comparison of the difference value with a threshold value. The correction value is set off against the electrical signal value generated from the integrated metering, and the value resulting from the setoff is used for exposure control of the camera.

    摘要： A photographic camera with an electrical circuit for generating an electric signal proportional to the relative motion between the object sighted and the camera. The camera has a control circuit which receives the generated signal and provides an output signal which is fed to a display and/or control device. An indicator is provided to the user of the camera for indicating whether the exposure time is set too long for the relative motion present between the object and the camera. Automatic control of the camera is also provided. Individual photosensor elements are arranged in two alternately connected groups within the electrical circuit. The individual photosensor elements may also be arranged in two substantially perpendicular directions to provide a relative motion signal corresponding to two dimensional movement between the object to the photographed and the camera.

    摘要： The invention relates to a brake system for a vehicle having at least one brake circuit which includes at least one wheel brake, one inlet valve, one outlet valve, and one return device. The return device has at least one first pump device and one second pump device, having respective inlet valves and outlet valves. The pump devices have a delivery cycle offset from each other. An additional valve is located in every supply line of every pump device for preventing negative pressure produced in an intake phase of one of the pump devices from being applied to an inlet valve of another pump device.

    摘要： The invention is based on a reciprocating piston pump having two radial pistons disposed symmetrically to one another, which are drivable to a reciprocating motion by an eccentric disposed between them and are held in contact with the eccentric by a hoop spring that engages the pistons. For ease of installation, the invention proposes embodying the hoop spring as a bent wire part, with two open, hooklike eyelets on their ends, which ends are inserted into annular grooves of the pistons and enter into a snap connection with them in order to hold the pistons tightly against the eccentric.
