Abstract: A braking force distribution linkage for a muscular energy-actuated parking brake system of a motor vehicle, in which the braking force is transferred at least via control cables both to one gear of the vehicle's transmission and to the wheels of at least one driven vehicle axle, the wheel brakes on each vehicle axle being respectively articulated via a compensation element. A linkage, lever and balance arm arrangement ensures a sufficient parking-hold effect on a road surface with differing nonskid properties, even in the event of failure of a portion of the braking system.

Abstract: The object of the invention is to provide a lock-in process and device for a YIG-tuned oscillator which takes into account ageing and hysteresis of the YIG-tuned oscillator. This object is attained in that during a predetermined frequency change, the frequency of the YIG-tuned oscillator (1) is preset by means of a microprocessor (17) that progressively changes the current (I.sub.SP) in the main tuning coil (13) of the YIG-tuned oscillator (1) by an iterative capture routine, until the capture range (.DELTA.FM) of the switched-on frequency-locked loop, which changes with the coil current (I.sub.SP), includes the new operating frequency (f.sub.SET). The switched-on frequency-locked loop then pulls the oscillator frequency into the capture range of the PLL and the PLL locks-in the oscillator frequency to the new operating frequency (f.sub.SET). The microprocessor (17) interrupts the capture routine when a PLL-LOCK detector (11) announces to the microprocessor (17) that the new operating frequency (f.sub.

Abstract: The power train of a motor vehicle has an automated clutch which can transmit torque from a prime mover to a transmission in response to signals from an electronic control unit. The latter causes the clutch to transmit a constant torque during a first interval, to thereupon transmit a gently varying torque during a second interval if the operator of the motor vehicle fails to carry out certain necessary operations prior to elapse of the first interval, and to thereafter transmit a pronouncedly varying torque during a third interval if no remedial undertakings were completed during the second interval. The third interval is cut short if the engine tends to choke, and the full or shortened third interval can be followed by a fourth interval corresponding to the first interval or by a further interval corresponding to the second interval.

Abstract: A method and device for electrically connecting enameled wire ends with contact surfaces. The enameled wire is stripped and pressed against the contact surface. The wire is charged with at least one of an electromagnetic and an acoustical energy. The enamel layer of the wire end is destroyed with the first energy in a first step. This is accomplished by charging the region with at least one of a first electromagnetic energy and a first acoustical energy. The enamel layer of the wire end is only partially destroyed in the first step through the pressing of a region of the wire end against the contact surface with a first pressing force. The wire is permanently connected to the contact surface with a second energy in a further step. The same region of the wire is pressed against the contact surface with a second, lower pressing force in the subsequent process step. It is charged with a second energy and connected to the contact surface so as to conduct electricity.

For absorbing particularly high pressures the rod head (4) has a relatively large diameter, so that the ball receptacle (14) extends close to the circumference of the piston (1). The piston wall (15) laterally surrounding the rod head (4) has a circumferential indentation (21) which, in the inwards direction, forms an uninterrupted undercut enclosing the spherical rod head (4).

Abstract: Direct-injected, four-cycle internal combustion engines can be operated advantageously with charge stratification, with the fuel being injected into the combustion chamber during the compression stroke of the piston in the cylinder as a conical fuel stream. To ignite the stratified mixture cloud, an igniting spark jumps between the electrodes of a spark plug and thus contacts an ignitable mixture. In order to guarantee sufficient preparation and stable ignition and combustion of the fuel/air mixture in the long term, it is proposed that the electrodes be located outside a conical jacket of the fuel stream and that the combustion chamber roof be so designed that the conical jacket is formed during injection between the injector and the spark plug close to the wall of the combustion chamber roof. The mixture guided in the conical jacket is deflected outward in the direction of the electrodes as a result.
