摘要:
A corner shield for protecting corners of objects for placement on a substantially horizontal surface comprising a body and an elongated protector. The body comprises inner and outer support sections with a slot therebetween for receiving an elongated protector. The slot has an outer section and an inner section with the outer section angled inwardly from bottom to top by a sloped angle of at least 2 degrees from perpendicular relative to the surface.

The present invention relates to a process for preparing polyether polyols, in which at least one hydroxyl-comprising fatty acid ester and/or at least one hydroxyl-modified fatty acid ester is reacted with the aid of a double metal cyanide catalyst in at least two process sections with in each case a mixture of ethylene oxide and at least one further alkylene oxide different from ethylene oxide.

A receptacle device that is attachable to a motor vehicle includes a receiving tube into which an insertion tube of an adapter having a trailer ball can be inserted. The insertion tube is held in the receptacle tube with the help of a splint. In order to eliminate play between the insertion tube and the splint, the insertion tube is pressed against the splint by a pressure piece. A first segment of the pressure piece fits the inner diameter of the receiving tube, so that the pressure piece can be held by said receiving tube, while a second segment engages precisely in the insertion tube in order to be held thereby.

The invention relates to a pivoting device, by means of which a vehicle door (10), in particular a wing door, is in the normal case mounted on a body (36) of a motor vehicle and can be pivoted between an open position and a closed position, wherein the pivoting device comprises a separating device (18), by means of which the vehicle door (10) can be detached from the body in an emergency, in particular after a rollover. The invention also relates to a method for controlling a separating device (18).

The invention relates to a device (12) which is used to press a pressure shoe (10) against a counter surface, comprising at least one at least partially flexible pressure body (16) which is supported on the bearing body (14), said pressure body comprising at least one cavity (18) which can be impinged upon by pressure fluid in order to produce a predetermined pressing force over a corresponding pressure body volume.
摘要:
System and method for influencing and/or monitoring a press pressure profile along at least one of a web running direction and a transverse direction in an extended press nip used for treating a material web. The system includes a measuring device for measuring the press pressure profile, a profiling arrangement which participates in producing the press pressure profile, and a data storage device for storing data related to the profiling arrangement. The method includes storing, in a data storage device, data relating to a profiling arrangement which participates in producing the press pressure profile, retrieving the data and acting on the profiling arrangement based on the data. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
The present invention relates to a circuit arrangement for a composite fuel cell system comprising a plurality of individual fuel cells connected in series, the voltage of the individual fuel cells being monitored, in which case components are present which enable the individual fuel cells to be bridged in the sense of a low-resistance parallel circuit. Furthermore, the invention relates to a method for operating a circuit arrangement of this type, in which case the fuel cells are bridged if the magnitude of their voltage falls below a specific threshold value or if the sign of their voltage has changed relative to normal operation, or alternatively in which case the components are controllable switches which are driven if the composite fuel cell system is intended to be discharged.
摘要:
A process is suggested for checking the catalyst performance in internal-combustion engines, in which by means of detected operating parameters of the internal-combustion engine similar operating conditions are determined. It is suggested to compute from a defined number of measured exhaust gas values during a similar operating condition a statistically backed average exhaust gas value and compare it with a permissible exhaust gas value stored for this operating condition, so that a defective catalyst is recognized in the event of a deviation of the actually determined exhaust gas value from the permissible exhaust gas value.
摘要:
A process for monitoring the operation of a system for the aftertreatment of exhaust gas utilizes respective temperature sensors assigned to catalysts in the exhaust gas system. In addition, a sensor for detecting the NOx content in the exhaust gas is assigned to a reduction catalyst. The detected values, or functions thereof, are in each case compared with the definable reference values and when these definable limit values are exceeded, a corresponding defect information is triggered.
