In the installation position of the support bearing, the flange is supported on one edge of a receiving lug receiving the bearing. The bead-like bush endpiece facing away from the flange engages behind the other edge of the receiving lug and has supporting elements which engage in a snap-like manner behind the edge of the receiving lug. An abutment is assigned in the bush endpiece at an axial distance from the edge of the receiving lug. A reliable bearing support in the receiving lug in each axial direction is achieved respectively by the flange and supporting elements.

Abstract: A method for regulating the mixture or fuel quantity fed to the cylinders of an internal combustion engine uses an arrangement for the variable metering of the mixture or fuel quantity to the cylinders of the internal combustion engine, a device for acquiring the actual value of the mixture or fuel quantity fed in, by means of measuring the stroke of a valve device, arranged movably in the metering arrangement, and an arrangement for regulating the valve movement. In order to be able to determine the actual value of the metered quantity with great accuracy where simple and cheap sensors are used, the stroke duration of the valve device allocated to each cylinder is determined with a position sensor and regulated to an identical value for all of the valve devices.

Abstract: The light mixing device for the uniform spectral and intensity-related distribution of light coming in from n.times.n optical fibers to n.times.n outgoing optical fibers. The incoming and the outgoing optical fibers are distributed into n groups of n each respectively, each group of optical fibers being optically connected with a first front face of a mixer lamina. The n mixer laminae of the incoming optical fibers are stacked and arranged to form a first stack, and the n mixer laminae of the outgoing optical fibers are stacked and arranged to form a second stack, in each case congruently and above one another in such a manner that the free second front faces of the mixer laminae of both stacks form one surface respectively. The surfaces of both stacks are directed against one another and arranged in a manner in which they are rotated by 90.degree. with respect to one another, and are subsequently optically connected with one another.

Abstract: A hydraulic brake system for a motor vehicle with rear axle drive and front axle/rear axle brake circuit division is equipped with an antilocking brake system, a traction control device and an electronic braking force distribution control device. In order to effect these regulation and control functions on the rear axle of the vehicle, a pressure modulator is provided which has a modulation chamber connected via brake pressure control valves to the rear wheel brakes. This modulation chamber is separated by a modulator piston from a control pressure space to which the outlet pressure of an auxiliary pressure source can be connected under valve control. The modulator piston is displaced by a return spring into the position corresponding to the maximum volume of the modulation chamber, which is the initial position both for normal braking and for traction control operation.

Abstract: An optical range finder includes two detectors for minimizing frequency dispersion affects of the detectors on the system. The optical range finder is calibrated by locking a voltage controlled oscillator onto adjacent null modulation signal frequencies and determining a calibration time for each adjacent frequency. Once the calibration time is determined, the range finder transmits its modulated light signal to a target device and back. The signal reflected back is detected and a measurement time delay is calculated for each of the adjacent modulation signal frequencies. From these measurements, the actual distance between the target and the device can be calculated. The multiple frequency measurements allows for statistical averaging of random errors in the system.

Abstract: A method produces hollow gas exchange valves, in particular with a cooling medium introduced into the hollow valve stem. The hollow of the valve stem is preferably drilled from the valve head side and, after the introduction of the cooling medium, sealed again by surfacing. A thin filling piece is inserted to a defined depth into the drilled hole temporarily holding the weld pool of the surfacing weld. By means of surfacing, it is possible to achieve cost savings over other sealing methods. The surfacing is preferably performed by a welding method in which the workpiece is not part of an electric circuit through which the welding energy flows. Preferable methods include gas welding, electron beam welding or laser welding. With these methods, so-called edge effects can be avoided.

Abstract: A quick-change arrangement for an excavator is provided for the exchange of tools which are detachably fastened by way of locking elements to an adapter of a bending arm and held on the bending arm so that the tool can be swivelled around a horizontal axis. The locking elements comprise a piston, which is coaxially arranged in a housing and has end-side locking pins which, by way of an interposed pressure spring, can be adjusted into a moved-out operative position and, by way of a pressure admission controlled by the control unit, can be adjusted into a moved-in inoperative position inside the adapter. By this construction of the device, it is achieved that the locking pins are subjected to the tension of the pressure spring in the operative position.

Abstract: A waffeline-configured, surface-mount transmission line module contains a two-dimensional arrangement of periodically distributed conductive surface mesas and channels. Within the channels are segments of dielectrically surrounded conductor. The geometry of the arrangement of segments among the waffleline channels is defined in accordance with the intended signal coupling functionality of the interconnect structure. For example, in the case of a signal splitting application, the conductor segments may be arranged in a tree-like configuration between an input port and multiple output ports. Isolation resistors may be disposed within the channels of the waffleline between adjacent locations of diverging conductor runs among the mesas of the waffleline.

Abstract: A grip control for a handle for unlocking vehicle doors, which handle in a rest position can be retracted flush with an outer contour in a recess of the vehicle door. The handle can be moved in a controlled manner out of the recess into a ready position for opening the vehicle door. Subsequently, the handle can be pivoted out further counter to a spring force with actuation of a lock unlocking device. The grip control includes two pivot levers which are articulated at one side fixed to the door, and on the other side are connected in an articulated manner to the handle. When the pivot levers are pivoted in a controlled manner, they displace the handle into a ready position parallel with the outer contour of the door, and they then permit an additional pivoting-out movement of a side of the grip counter to the force of a spring.

Abstract: An antilocking braking system for a road vehicle performs brake pressure control on the principle of changing the volume of an output pressure chamber of a pressure modulator connected to the wheel brake. The modulator has a control pressure chamber which is separated by a piston from the output pressure chamber into which the output pressure of an auxiliary pressure source is permanently introduced via an inlet control valve. The piston is held in its end position associated with minimal volume of the output pressure chamber. Connected in series with the inlet control valve is a non-return valve which prevents a drop in the pressure in the control pressure chamber in the event of a failure of the auxiliary pressure source. Volume increases in the output pressure chamber required for pressure reduction phases of the antilock braking control are controlled by an outlet control valve.

Abstract: A packaging structure mounts integrated circuit chips in a nested, cavity-up configuration, so as to permit access to the modules for reworkability, but without the use of a separate printed circuit board for support and interconnect among the modules. Each monolithic integrated circuit module comprises a cavity-up leadless chip carrier which is affixed to its own dedicated thermally and electrically conductive mounting base, that effectively plugs into an underlying ground plane, heat sink support. The mounting base may comprise of a thin conductive plate having a cylindrical stem, through which the mounting base is retained within an aperture in the underlying support. The underlying support has a plurality of cylindrical stem engaging apertures distributed in a matrix configuration, so that the insertion of a plurality of chip carrier mounting bases into the apertures of the matrix causes the mounting bases to be aligned edgewise in a tight edge-to-edge array.

Abstract: In a continuous hot rolling system, at least one melt-cut torch is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material and a leading end of an adjacent succeeding hot material. An injected flow of cutting gas from the melt-cut torch is blown against a portion of at least one of the trailing end of the preceding material and the leading end of the succeeding material to melt-cut the portion. The portion extends from an end surface of the one end over a predetermined length. The trailing end of the preceding material and the leading end of the succeeding material are forced against each other and are butt-joined to each other. By doing so, there are produced joining surfaces superior in surface accuracy and high in temperature, to allow joining to be high in accuracy and strength. This joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling.

Abstract: A barrier is manufactured by inserting a cage frame into the mold. The cage frame forms a clearance gap between the frame side walls and the mold side walls. The cage frame is first substantially filled with vehicle tire material and secondly filled with non-recyclable plastic material. An adhesive-type liquid is poured into the clearance gap to fill the sides of the mold. The top of the mold is coupled into place and the adhesive liquid is poured through the top to fill up the mold. The mold is then cured to produce the barrier.
