Abstract: In a switching device for the interior lighting L of a motor vehicle, having a timing element R1 C1 which is controlled by a gate contact switch TK which is opened by closing a vehicle door and which sets on the interior lighting during a certain time lapse after closing the door, a second timing element R2 C2 is provided to be controlled by the closing of the gate contact switch TK and to set off the interior lighting L after a predetermined time interval, when the ignition switch ZS is open. Thereby, the discharge of the vehicle battery is prevented due to the interior lighting L when a door remains inadvertently open, but, when the ignition is turned on, the interior lighting L remains on if a door is open.

Abstract: For changing the compression ratio of a reciprocating piston internal combustion engine the piston 3 consists of an outer piston part 7 and an inner piston part 10 which are connected with each other by a thread 13,14. By turning the outer piston part 7 by means of a bushing 18 which is axially fixed, but rotatable around piston axis 15 and which is in engagement with the outer piston part 7 by means of a longitudinal gear 19,20, the outer piston part 7 can be turned steplessly during operation with respect to the inner piston part 10, whereby the outer piston part 7 is displaced along the piston axis 15, thus changing the volume of the operating chamber and thereby the compression ratio.

Abstract: In an externally ignited internal combustion engine for a vehicle with an electronic device for controlling the gas mixture composition and the point of ignition a leaner fuel-air mixture and the an earlier point of ignition is set before the maximum permissible speed is attained. The reduction of power of the combustion engine caused thereby shows the driver that the speed of the combustion engine approaches the maximum permissible speed at which the fuel supply and the ignition will be interrupted. This should cause the driver to release the gas pedal or switch into the next higher gear.

Abstract: A transmission for motor vehicles having a conical-disc band transmission placed in a casing, a reduction gear and, if necessary, a differential. In order to achieve an optimum transmission-ratio range for motor vehicles and good efficiency, the reduction gear contains two forward speeds and is connected to a fixed gear on the power take-off shaft by means of an additional fixed gear. The driving disc pairs of the conical-disc band transmission are located directly on a section of the drive shaft and on the power take-off shaft. The reduction gear and the conical-disc band transmission can be actuated by means of conventional synchronous clutches. The transmission case is longitudinally fitted with a center wall which subdivides the space into two compartments, one of which is closed by a front cover and the other by a rear cover. While one compartment contains the reduction gear and, if necessary, the differential, the other compartment contains the conical-disc band transmission.

Abstract: In order to be able to enlarge the width of web 13 between adjacent valve seating rings 6 of a light-alloy cylinder head 1 for reciprocating internal combustion engines, an external diameter D1 of valve seating surface 11 at the valve seating ring is selected, which is smaller than the external diameter D2 of the total valve seating surface 7. In order nevertheless to give valve seating ring 6 the required strength, the smallest internal diameter D4 is smaller than the internal diameter D3 of the valve seating surface. Throttling the flow is avoided by a transition from D4 to D3, which is advantageous to flow.

Abstract: An automatic plant for stacking sheet steel pressings received from a press line comprises a pivotal depositing table (5) with two depositing devices (7,8) at each of which several pressings can be deposited in the stack. Associated with each depositing device is a grab (9,10) and a storage system which comprises a turntable (17,18) with two storage devices (A,B,C,D,). The storage devices of each system are charged alternately, while the other loaded storage device is replaced by an empty storage device. When one storage device is full, the relevant turntable (17,18) is rotated through 180.degree., so that an empty storage device replaces the loaded storage device, a distributing carriage (23) common to both turntables, picks up the loaded storage devices, shifts them to a delivery station, picks up an empty storage device at a pickup station, and brings the latter to the relevant turntable to replace the loaded storage device which has previously been collected.

Abstract: The invention relates to a coupling means between an output control member of an internal combustion engine, in particular for automotive vehicles, and an actuator member, which coupling means in the range of small actuations of the actuator member does not open the output control member at all or only slightly, and only at larger actuations does it open the output control member in a noticeable fashion and thereafter moves it into a full-load position. Such a coupling means makes possible an enlarged operative range for a control device which controls the output control member in dependency of the position of the actuator member and at least one operating parameter of the internal combustion engine in a range lying between the full-load position and the minimum opening position determined by the given position of the actuator member.
