摘要:
A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM1) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATMTOT) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.

The invention relates to an automatic belt tensioner comprising a basic part that is connected to a tensioning part so as to be rotatable about a common axis of rotation, a helical spring that is joined to the basic part and the tensioning part, and a wrapping bush which is wrapped at least in some areas with a radial enveloping force by means of the helical spring. According to the invention, the material of the wrapping bush contains reinforced plastic in order to ensure that the belt tensioner provides good damping and good cushioning properties if possible during the entire service life thereof while being universally usable and having a simple design.

A method for forming honeycomb structures, such as wall-flow honeycomb filters, which utilizes extrusion of multiple material supplies at once. Such methods may be used to form intermittent plugs or other structures in the cell channels during the extrusion process, for example. A die assembly is provided which includes secondary feedholes machined in the pins for intermittently or periodically injecting secondary material (e.g., plug material) into the cell channels of the honeycomb structure while it is being extruded.

In order to improve an actuating device for a trailer coupling, in particular, for actuating a trailer coupling with a ball neck movable between an operative position and a rest position, for example, a locking device of such a trailer coupling, comprising a device base which can be mounted on the vehicle and a lever which is mounted on the device base so as to be movable and can be moved from a starting position, in which no actuation of the trailer coupling takes place, into an actuating position, whereby the trailer coupling is acted upon by means of a movement transfer device, in such a manner that this can be operated as favorably as possible it is suggested that a securing device be provided on the lever which secures the lever against any actuation in the starting position.

A method is provided for determining a ranking score for an image or group of related images among a plurality of images accessible by a search engine, such that the ranking score is usable to determine the order in which the images are presented in the results of a search conducted by the search engine. The method comprises monitoring the number of times the image (or the images in the group of related images) is presented for viewing by predetermined users in the results of searches conducted by the search engine. The level of active interest shown by the predetermined users in the image or images presented for viewing in the search results is then monitored, for example by determining the number of times that users select a thumbnail of the image for viewing on an enlarged scale. Finally a ranking score is assigned to the image or images based on the monitored level of active interest as a proportion of the number of times the image or images are presented for viewing by the predetermined users. This then enables an identified set of images to be ordered in such a manner as to take into account the ranking scores of the images, in order to enable users to access the images that they require more quickly and conveniently.

A process provides access data to a transportable subscriber station, for establishing access to a service provider station. A first access mode which can be provided using first access data includes a first network that is accessible by means of a selectable network account, a first switching station, and a second network. A second access mode can be provided by means of second access data by way of the first network and a fixedly defined second switching station. If first access data for the selected network account are not available a request for the second access mode is made to the service provider station, using the stored second access data, and a request is made for first access data for the selected network account in the second access mode. This requested access data for the selected network account are transmitted to the subscriber station in the second access mode and stored for the selected network account in the subscriber station.
