Abstract: A foot brake valve (2?) of a pneumatic brake system in a motor vehicle has an installation plate (4?), on which a brake pedal (14) is pivotably mounted and to which a housing (18?) of a control unit (16, 26) is fastened. A spring-loaded plunger piston (36) in actuating contact with the brake pedal (14) is guided axially movably in an annular collar (50) projecting upward out of the installation plate (4?). For fastening the housing (18?) of the control unit (16, 26) to the installation plate (4?), the housing (18?) has an intermediate flange (48) which is screw-connected to the main part of the housing (18?) and has the annular collar (50). The intermediate flange (48) is coaxially rotatably about a vertical central axis (32), and is connectable in non-positively locking fashion to the installation plate (4?) via a releasable clamping connection (62).

Abstract: In some examples, the technology identifies media and provides a user with supplemental information (e.g., supplemental media, a selectable link, etc.) based on the identity of the media. In other examples, the technology identifies media and provides a consumer with an option to click on a link associated with the media with a remote control to direct the video stream directly to a website sponsored by the commercial entity associated with the media. In other examples, the technology identifies media displayed on a subscriber's first computing device and displays the same media and/or a related media on the subscriber's second computing device.

Abstract: A bipolar assembly for filter-press type electrolyzers is described comprising a single sheet, whose two faces work respectively as anodic and cathodic wall, characterised by a design of perimetral flanges which greatly simplifies its construction enhancing its reliability. The peripheral flanges are made of a first flange obtained by folding the peripheral portion of the single sheet and of a second flange formed by a rod or a tube with quadrangular section or, alternatively, the first and second flange are pre-formed by folding of adequate strips subsequently fixed to the single sheet. The electrolyser resulting from the assemblage of a multiplicity of assemblies of the invention is particularly suited to the process of electrolysis of hydrochloric acid solutions carried out with chlorine-evolving anodes and oxygen-consuming cathodes.

Abstract: The invention relates to an electrochemical half cell (1) which consists of at least one membrane (4), an electrode (3) as anode or cathode which optionally produces gas, optionally an outlet (8; 16) for the gas and a support structure (12) linking the electrode which optionally produces gas with the back wall (15) of the half cell. The support structure (12) divides the interior (13) of the half cell (1) into vertically arranged channels (5, 9). The electrolyte (14) flows upwards in the electrode channels (9) facing the electrode (3) and flows downwards in the channels (5) facing away from the electrode (3). The electrode channels (9) and the channels (5) facing away from the electrode (3) are interlinked at their upper and lower ends.

Abstract: The invention concerns an improved electrode particularly useful for electrochemical processes forming gaseous products. The electrode is made of a composite structure comprising a shaped sheet having a profile of the "venetian blind" type, which provides for ensuring the necessary stiffness and improved local fluodynamics, and a mesh having the same "venetian blind" profile, provided with an electrocatalytic coating. The mesh is fixed by spot welding to the sheet in order to have the two profiles substantially coincident.

Abstract: A transport container for wafer-shaped objects to keep particles away from and remove them from the interior of the transport container when opening the latter, in particular also those particles located in the door gaps, without restricting handling. Cleaning in the form of a self-cleaning process should also be effective when a plurality of transport containers are stacked one on top of the other and the latter should be optionally accessible. At least parts of the rear wall region of a closable container enclosure are constructed as a plenum chamber which has a closable air inlet and a closable air outlet in the base region and cover region, and a connection is formed from the latter to the interior of the container via a filter. The air inlet is constructed so as to complement a connection of a gas reservoir and an air outlet of an additional transport container for coupling. The arrangement is applicable in the manufacture of integrated circuits.

Abstract: An electrode structure for membrane electrolysis cells comprises a planar electrode part which is joined by metal spacers to a sheet metal support serving as current distributor. The spacers are made in the form of a spring clip mounting comprising a spring part and a springless part, the spring part being fixedly joined to the support while the springless part is integral with the electrode part. In case of the need to reactivate or repair the active electrode parts the spring clip mounting permits them to be separated easily from their supports and then they can be sent away directly for reactivation or repair.

Abstract: The invention relates to an annular gap-type ball mill for continuously pulverizing in particular mineral hard materials comprising an upright grinding container closed by a cover, and housing a rotor whose cone-shaped outer surface limits with the cone-shaped inner surface of the grinding container a grinding gap communicating with a feed aperture and containing grinding pellets, the rotor having a top portion being adapted in its shape to the inner surface of the cover, and including within its range a discharge opening. The annular gap-type ball mill is characterized in that the top portion of the rotor is conical to limit with the cone-shaped cover an annular discharge gap whose lower end of maximum diameter ends in an annular chamber at the open upper end of the grinding gap. The grinding pellets are prevented from sinking down in the grinding gap of which 100% are utilized for the grinding operation so that the residence time required for the pulverization of the mineral hard materials is reduced.

Abstract: A bipolar electrode has plate-like anode and cathode parts. The anode and cathode parts are secured together, edge-to-edge, to form a single element in one plane by an intermediate connecting piece. The intermediate connecting piece itself is a composite element having parts of materials which are compatible with the respectively adjacent anode and cathode. The two parts of the composite element are joined together by hot isostatic pressure, explosion-plating or diffusion-welding into the composite body, the resultant composite body then permitting welding of the respective anode and cathode plates to the respective anode part and cathode part of the composite element or body.
