Abstract: A flexible gap covering between an adjustable steering column of a motor vehicle and an instrument panel, on one side, is fastened to the steering column covering and, on the other side, is fastened to the instrument panel. A flexible gap covering which permits a large adjusting range of the steering column, is easy to mount and has a corresponding appearance, has an upper covering and a lower covering. The upper covering is formed of two parts, which are arranged above one another and are fixedly connected with one another in a joint overlapping area. At least one tensioning element is applied to the overlapping area on the side facing away from the vehicle occupant compartment.

Abstract: A roof system for a motor vehicle with at least two covers (2, 3) which are located in a fixed motor vehicle roof (1) with an intermediate section (1B) of the fixed motor vehicle roof (1) located between the covers (2, 3). To produce an economical roof system which can be matched to any vehicle roof size and shape, and which is suitable for retrofit installation, a covering is provided on the intermediate section (1B) between the covers (2, 3) which is formed preferably as a film and which has an outer surface with a visual appearance that is matched in that of the covers (2, 3).

Abstract: A contact roller system of a winding machine for thin strip material has a shaft and pivot levers arranged in a row adjacent to one another on the shaft. The pivot levers have two contact roller segments moveable against slit rolls during a winding process by an actuating drive of the pivot levers. The two contact rollers are arranged on opposite sides of the pivot levers, respectively, and form a contact roller segment pair positioned adjacent to one another such that between neighboring end faces a gap required for rotational movement of the contact roller segment pairs is formed. The contact roller segment pairs are freely rotatably supported and rotate about an axis of rotation extending parallel to the pivot axis of the pivot levers. The axes of rotation of the contact roller segment pairs have a common pivot radius.

Abstract: A roof frame assembly of an openable motor vehicle roof for installation in the roof opening of a fixed motor vehicle roof is provided. The assembly includes a roof frame including at least one holding device for providing additional stabilization of the roof at least in the side area of a roof frame and at least one support tube attached to the frame via the holding device or devices. The at least one support tube is supported on one lengthwise member of the fixed motor vehicle roof to provide stability in the event of a side impact.

Abstract: High-strength sinterable lithium disilicate glass ceramics are described which can be further processed in particular by pressing in the viscous state to shaped dental products.

Abstract: An arrangement for holding beverage cans or similar receptacles in the interior of vehicles is provided inside, in the upper area of a glove compartment, and comprises at least one receiving part for at least one beverage can. The receiving part is displaceable from a covered inoperative position inside the glove compartment into an operative position in front of the dashboard, and a swivellably disposed glove compartment cover is assigned to the glove compartment. When the receiving part is displaced into the operative position, the arrangement does not require the opening of the glove compartment cover. The glove compartment cover extends only approximately to the lower edge of the arrangement, and the arrangement comprises at least one separate flap which has a low height and can be operated separately from the glove compartment cover.

Abstract: A knee support is arranged inside a body of the motor vehicle and exhibits a transverse frame member, which extends at right angles to the longitudinal direction of the motor vehicle, is held at rigid, lateral body structures, and is provided with at least one deformation element. This deformation element comprises several hollow brackets, defined by bracket walls, and is covered by a support wall, facing the occupants' knees. The deformation element exhibits a first hollow bracket segment, which runs along the support wall, and a second additional hollow bracket segment, which is arranged at an angle to the first hollow bracket segment, whereby the second hollow bracket segment is attached to the transverse frame member.

Abstract: Alkali silicate glasses are described which, in view of their good chemical stability and their optical properties and processing properties, are particularly suitable as a coating or veneering material for ceramic dental frameworks and hence for the production of all-ceramic dental restorations such as crowns or bridges.

Abstract: An apatite glass ceramic is described which is characterized by good chemical stability, a low expansion coefficient and high translucence, and is particularly suitable, by itself or together with glasses or other glass ceramics, as a veneering material for ceramic dental restorations.

Abstract: The present invention relates to a component, for example a tool, coated with a hard material, in particular diamond, a process for its production and a device for carrying out the process. The process for the production of the component coated with the hard material comprises the steps of: a) introducing a fine-grained cemented carbide or carbide-containing cement substrate into a vacuum system with a heating device and at least one gas feed connection; b) removing carbon from the carbides of a surface layer of the substrate at a substrate temperature in the region of about 900° C. to about 1400° C. and in an oxygen-containing atmosphere; c) introducing carbon into the surface layer of the substrate at a substrate temperature in the region of about 900° C. to about 1400° C. and in a carbon-containing atmosphere; and d) coating the substrate with the hard material.

Abstract: Method which includes passing a gas stream containing carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans and other acid gases through an aqueous alkanolamine solution to remove the carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans, etc., from the gaseous stream. Heat-stable alkanolamine salts form in the aqueous alkanolamine solution due to the acid contaminants (other than hydrogen sulfide or carbon dioxide) removed from the gas stream. A base is added to the aqueous alkanolamine solution to convert all or part of the heat-stable alkanolamine salts into alkanolamine and simple salts. The base-treated aqueous alkanolamine solution is electrodialyzed in an electrodialysis cell containing ion exchange membranes. The purified aqueous alkanolamine solution can be used again to remove carbon dioxide, etc., from the gas stream.
