Abstract: A bitumen-based waterproofing membrane is provided with an improved edge for sealing with a contiguous membrane to provide a membrane system with improved waterproofing characteristics. A bitumen-based reinforced membrane sheet is coated with granular material to protect the membrane sheet from ultraviolet rays. However, a section of the membrane sheet is first covered with a piece of protective tape which prevents any granular material from being deposited on the lateral section of exposed bitumen beneath the tape. The membrane sheets are then cut immediately prior to the tape or at the edge of the granular coating and then rolled up. Accordingly, the lateral section of bitumen which is covered by the protective tape is on the innermost part of the rolled-up membrane sheet. During installation, the tape is removed and the exposed bitumen or selvage section is disposed below an adjacent or contiguous membrane. Heat is then applied for an easy and effective seal between two adjacent membrane sheets.

Abstract: A method for coating a transparent carrier plate includes coating a backside of the carrier plate with a first chromatic layer, applying a non-opaque metallic blocking foil coating on top of the first chromatic layer, and applying a second chromatic layer on top of the non-opaque metallic blocking foil layer. The method results in a coated carrier plate having increased color intensity and brightness. Further, by varying the hues in the first and second chromatic layers, a resulting hue may be provided that is different from the hue of the first and/or second chromatic layer. In addition, the hues of the first and second chromatic layers may be varied over the surface area of the carrier plate.

Abstract: The present invention relates to a painted sheet metal part, such as a car body, with a polyacid layer between the coat of paint and the surface of the sheet metal part and to a method for applying such a coating on the part before painting. Initially, the part is cleaned and de-greased, and subsequently the polyacid layer is deposited and stabilized. In order to be able to apply this layer without losing wet adhesion qualities of the coat of paint and the anti-corrosive effect of coating layer, while presenting fewer ecological disadvantages or harmful consequences, polyacids, which comprise homopolymers or copolymers of carboxylic acids containing double bonds or of functional esters of carboxylic esters, or copolymers of carboxylic acids with vinyl compounds, are used pursuant to the present invention as the protective bonding layer. The polyacids used are further combined with polymers having a glass transition temperature above 100.degree. C.

Appropriately, the opening jet (10) as well as the active-substance jet (11) are inclined relative to the book spine (7). The active-substance jet (11) is moved relative to the book (1) by means of a swing arm (3).
