A pipe switch for pneumatically conveying a material such as bulk material includes a housing provided with a first port, a second port extending coaxially with the first port and a third port having an axis extending at an angle of less than 90.degree. relative to the axis of the second port, with the housing accommodating a cock which extends between opposing side covers and by which the first port is selectively connectable with the second port and with the third port. In order to reduce a danger of accident and to allow easy access to the interior of the pipe switch, the entire drive unit for actuating the cock is connected to the pipe switch at one of the side covers, with all movable parts being housed within an external compartment defined by an outer wall mounted to the one side cover.

Apparatus is provided for automatically dispensing CO.sub.2 snow on articles moved by a conveyer underneath a snow storage container-dispenser outlet opening. The dispensing is controlled by a motor driven segmented drum with brush-like elastic blades closing the dispenser outlet opening actuated when an article is moved into place thereunder. The snow is generated from liquid CO.sub.2 flowing through cooling coils in the snow and dispensed through a nozzle in the upper portion of the container in response to capacity sensing means such as a photocell level detector to thereby keep the container snow level constant.

A support part serves is arranged in an instrument panel of a motor vehicle to hold a vehicle data display unit having an integrated navigation or radio unit. The support part has a single-piece frame composed of a magnesium pressure die cast material with a central holding frame for the unit and lateral holding frames for the air outlets. The support part is connected at one side to the instrument panel and another side to the cockpit cross member. Centering receptacles for the unit and further centering receptacles for the air outlets are arranged in the central holding frame and in the two lateral holding frames. Centering elements are arranged on the unit and on the air outlet correspondingly to the centering receptacles of the holding frames.

A covering element for covering an air duct on a dashboard in a motor vehicle is of one-piece design and has two lateral air outflow areas and a loudspeaker area arranged therebetween. Each lateral air outflow area is subdivided into a central area that can be connected to communicate with the air duct, and at least one further air outlet area, via which waste heat from electronic assemblies can be discharged.

The test elements are provided that are adapted to detect at least one analyte in a sample. At least some of the test elements are provided with a defect marking which contains information about defectiveness of the test elements. The test elements include at least one radiation-sensitive material. The test elements are exposed to at least one radiation, the radiation being adapted to induce marking in the form of at least one optically detectable change in the radiation-sensitive material.

Collaborative structured tagging enables a community of users to define different types of tags for online content. The diverse tag types provide a non-flat or dimensional tagging data structure that supports navigation and search for content, as well as comparison of the content. In one implementation, the collaborative structured tagging is employed in an item encyclopedia that offers community-authored information on various items in one or more electronic catalogs. In this context, the collaborative structured tagging facilitates comprehensive cross-product comparison and dimensional product navigation.
摘要:
A method of forming a gate stack for semiconductor electronic devices utilizing wafer bonding of at least one structure containing a high-k dielectric material is provided. The method of the present invention includes a step of first selecting a first and second structure having a major surface respectively. In accordance with the present invention, at least one, or both, of the first and second structures includes at least a high-k dielectric material. Next, the major surfaces of the first and second structures are bonded together to provide a bonded structure containing at least the high-k dielectric material of a gate stack.
