Abstract: A hydraulic unit is elastically supported by means of elastomer elements, through which bolts pass, on two legs of a mounting bracket that extend perpendicular to one another. The leg of the mounting bracket has recesses, open counter to the mounting direction of the unit, for receiving the elastomer element. With clamping means disposed on the bolt, the elastomer element is axially shortened and pressed against both the recess and side faces, located on either side of the recess, of the leg of the mounting bracket. With the shortened elastomer element, a positive and nonpositive engagement with the leg of the mounting bracket is achieved.

Abstract: A method and a system for monitoring the functional capability of a particle detector connected downstream, in the flow direction, of a particle filter, in which particles occurring upon the regeneration of the particle filter, in particular ions, are detected by the particle detector and the resultant measurement finding are compared with an expected finding. The measurement and evaluation are effected in a control and evaluation unit. The invention enables monitoring of the functional capability of a particle detector that does not interrupt normal operation and thus increases the reliability of the entire system.

The invention provides that the at least one magnetic-sensitive element protrudes at least partway into the recess.

Abstract: A method and device for sterilizing containers in which a plasma treatment is executed through excitation of an electromagnetic oscillation so that the plasma is excited in a vacuum in the vicinity of the container regions to be sterilized. Between arrival and discharge, the container regions to be sterilized are moved closer to the oscillation-generating device in the chamber, with continuous movement of the container and/or of the oscillation-generating device for one or more predetermined time intervals in such a way that a plasma is excited in these regions inside and/or outside the container. The chamber is provided with a transport apparatus inside it, which produces an essentially rotating motion of the container during the transport from the arrival to the discharge in the chamber.

Abstract: The invention relates to a self-boosting electromechanical disk brake with a frame caliper equipped with a wear readjustment device which for instance is automatic and which upon tensing of the disk brake stores energy by prestressing a torsion shaft, which upon release of the disk brake converts this energy into a wear readjustment motion. In the process, a spacing between two brake lining holders of the frame caliper in the disk brake is decreased.

Abstract: A fuel injector for an internal combustion engine has a nozzle needle that opens or closes at least one injection opening. At an end oriented away from the at least one injection opening, the nozzle needle has a step-shaped widening, which forms an end surface oriented toward the at least one injection opening. The end surface, an end surface of a first booster, and an end surface of a second booster delimit one side of a control chamber; an actuator moves the first booster and the second booster into or out of the control chamber.

Abstract: An actuator for a control unit has a control motor with a motor power takeoff shaft; a control shaft that carries the control unit; and a step-up gear, disposed between the motor power takeoff shaft and the control shaft, as well as a restoring device for restoring the control unit to a basic position if the control motor fails. To make it possible to use a single-stage step-up gear with a major step-up ratio and with advantages in terms of installation space, weight, and production costs, the restoring device has two separate energy-storing means, preferably embodied as restoring springs, of which one feeds back to the motor power takeoff shaft and the other feeds back to the control shaft.

Abstract: An apparatus for metering a urea or a urea-water solution for delivery to a catalytic converter assembly for removing nitrogen oxides from the exhaust gases of a Diesel engine, includes a housing block supporting function components communicating via a line, formed by recesses in the housing block, for transporting the reducing agent, and the walls of the line are formed by the housing block. This apparatus assures a simple line layout for reducing agent with a minimum number of sealing points that is accordingly appropriate for large-scale mass production.

Abstract: An apparatus for forming a mixture of reducing agent and exhaust gas, having a mixture-forming region into which an exhaust gas and a reducing agent can be introduced, wherein the wall of the mixture-forming region is embodied at least in part with protuberances and indentations, and in particular in corrugated fashion.

Abstract: An apparatus for trussing a bird comprising a main body having a platform for supporting the bird, the platform and main body having a bird keel end and a bird wishbone end, clamping means movably mounted on the main body for securing the bird on the platform and releasing the bird from the platform, shackle means mounted on the main body and being disposed above the bird keel end of the platform for receiving and at least temporarily securing the legs of the bird, a leg engaging and supporting means movably mounted on opposite lateral locations of the main body for tightening leg knuckles of a bird into the shackle means before flexing, for preventing twisting of the legs and for bending the legs over the wings, a first drive means operably engagable with the clamping means, the shackle means and the leg engaging and supporting means to sequentially clamp the bird, shackle, stretch and flex the clamped birds legs and to release the clamped bird.

Abstract: A method for diagnosing a fuel injection device which includes a piezoelectric actuator, with which a valve element is actuated. The fuel injection device is connected to a diagnostic device which applies a defined voltage to the piezoelectric actuator. The charge introduced into the piezoelectric actuator, and from that a capacitance of the piezoelectric actuator, are ascertained by means of the diagnostic device.

Abstract: An electromagnetic valve is provided with an elongated tappet guided axially displaceably in a tappet guide, and with a sealing body, embodied on the tappet, that can seal against a sealing seat. So that the valve can be produced more economically yet can be regulated more precisely, the sealing seat and the tappet guide are embodied in one piece. The adjustability of the valve is assured in particular by an adjusting ring.

Abstract: A method of operating a plurality of clean room in a compound within a common enclosure and supplying each room with filtered air by a blower-filter unit by arranging the clean rooms and the blowers connected thereto in two parallel spaced rows with a corridor therebetween, and permitting filtered air to escape the clean rooms from beneath the walls of the clean rooms. Continuous operation of the blowers produces a bubble-like volume of air surrounding the blowers which consists primarily of clean, recirculated air escaping from the clean rooms. By arranging the clean rooms and blowers so that the clean air bubble produced by each blower overlaps the bubbles produced by at least two other blowers, the entire compound can be contained in a highly purified atmosphere consisting primarily of recirculated filtered air. A portion of the air from one or more clean rooms may be discharged in an upward direction through an opening in its top wall.
