On the surface of the base body, an electrically insulating first material is arranged in layer form at least above the through-hole contact in method step B), and thereafter an electrically conductive second material is applied above through-hole contact (10) in method step C). Then a solder contact (30B) that electroconductively connects through-hole contact (10) through passivation layer (25B), which is formed from the first material by sintering, is formed by hardening in method step D).

Abstract: In a fuel-injection valve, a holding member which bears a plug as atomizing and metering element is inserted in a valve bore. A replaceable diaphragm makes it possible to adjust the precise discharge quantity of the fuel-injection valve by replacement of said diaphragm.

Abstract: A throttle valve 4 is pivotally mounted about a shaft 3 within a connection-piece housing of a throttle-valve connection piece. In order to reduce the air leakage rate, means are provided for eddying the leakage air which, when the throttle valve is closed, passes between it and the wall of the bore of the connection-piece housing. The connection-piece housing preferably has two bores which open into each other forming a crescent-shaped step, against which the throttle valve rests in the closed position and a reduction in cross section on one side in the bore of the connection-piece housing is provided by an arcuate transition to the bore of smaller diameter and the crescent-shaped step is located on the opposite side.

Abstract: In an arrangement for regulating the idling speed of rotation of an internal combustion engine by influencing the intake by means of an electromagnetic control element, a ferromagnetic actuating element is provided within the field of influence of a solenoid. There also acts on the actuating element an auxiliary spring which moves a valve element against the force of a return spring in order to establish an average rate of flow of air when the solenoid is without current. If the solenoid is acted on by current, the actuating element is moved away from a stop so that the valve element can adjust itself only under the influence of the force of the solenoid and of the return spring.

Abstract: In an electric clock movement, the electronic components, such as an IC chip (9), a quartz crystal (10) or a diode (12), instead of being fastened to a circuit board are fastened to an extension (8) on the back plate (2). For this purpose, the extension (8) is provided with holes (14) into which the leads (15) of the electronic components are inserted.

Abstract: When a valve-controlled pump is to produce either vacuum or pressure at a pump outlet 9 as a function of its direction of rotation it is necessary that a 3/2-way valve be switched as a function of the direction of rotation of the motor of the pump. In accordance with the invention this is effected by a direction detection device on the motor (1) which is coupled with the motor for the control of the 3/2-way valve. The direction detection device is formed in the manner that the motor housing of the motor (1) is mounted for rotation and is provided at its end with a structural part (11) having a control kidney (10) which is movable over a control surface (7). Since the motor housing must take up the counter moment when the motor is rotating, the control kidney (10) shifts upon the starting of the motor (1) into one of its two end positions depending on the direction of rotation of the motor (1), thereby causing the pump outlet (9) to be connected alternatively to pressure or vacuum.

Abstract: An apparatus is disclosed for electrically locking the doors of motor vehicles, wherein at least one motor is supported in a driver door and the motor is coupled with a lock mechanism by means of a connecting element, with a first switch coupled with the motor to be actuated thereby and a second switch coupled with the lock mechanism to be actuated thereby and also coupled with the first switch and with the motor, and the switches are connected with at least one additional motor coupled with a further lock mechanism. Structure is included to change the direction of the force exerted by the motor on the lock mechanism, for locking or unlocking the doors, respectively.

Abstract: An electrically heated spray nozzle assembly adapted to be mounted upon an automotive vehicle in a position to direct a fluid spray upon the windshield thereof includes a hollow angled pipe having a fluid inlet at one end and a spray nozzle at its other end. The pipe is enclosed in a housing made of heat-insulating thermoplastic material and a pill-shaped PTC heating element is mounted in a downwardly open chamber in the housing below the nozzle. The element is in contiguous heat exchange relationship with the pipe and nozzle and the power supply connections thereto pass through a plastic closure element closing the downwardly open chamber. The housing is circumferentially grooved for releasable engagement with the rim of an opening in the vehicle body. The PTC element has its temperature-resistance curve rising sharply at or about 0.degree. C. with its steepest portion below 50.degree. C.

Abstract: A liquid level measuring device for measuring the liquid level in a container, includes a fastening member for holding the device in a container, and a support with a lower end portion or prop extending into engagement with the container bottom. The support carries a liquid level sensing member and is connected to the fastening member through a resiliently yieldable connection, whereby the support is continuously urged into a constant position relative to the container bottom, so that an accurate indication is obtained of the liquid level in the container.

Abstract: An apparatus for controlling the traveling speed of a motor vehicle with an electric control unit acted upon by a speed dependent signal, which unit compares the actual traveling speed with a predetermined desired traveling speed, and upon a deviation transmits a signal, which is dependent on the size of the deviation, to a control stage. The control stage comprises a pneumatic actuator which acts on an element, preferably a throttle valve, which influences the ratio of a fuel-air mixture fed to the motor of the vehicle, as well as two electromagnetically actuatable valves coordinated to the actuator, the valves enabling the actuator to be admitted with reduced- and above atmospheric-pressure, respectively, or normal pressure, respectively. The control stage includes an electromagnetic system having an excitation coil and an armature cooperating therewith.
