Abstract: A glass pane having at least one electrical functional element is provided. The functional element comprises at least one electrical conductor and at least one terminal area located at an end of the electrical conductor, wherein the electrical conductor and the terminal area are formed from an electrically conductive layer deposited on a surface of the glass pane. A terminal wire is connected to the at least one terminal area by a soldered joint by way of a metal block having a flat contact area, and the flat contact area is soldered on a corresponding terminal area. A method for forming such a connection is also disclosed.

Abstract: Tray for containing food products that are to be heated up in a microwave oven, with an external foil cover and an internal closure film, the external cover providing a water vapor and oxygen barrier, while the internal film is permeable to microwaves.

Abstract: An inert composite electrode, such as an anode, for molten salt electrolysis consists of an active part in the form of a plurality of bar-shaped active elements, in particular of ceramic oxide, which are arranged with their longitudinal axes mutually parallel and in mutually aligned groups, an electrode holder which comprises a current-conducting plate, with one main surface of which the active elements are in firm contact with their end surfaces, and a joining arrangement which joins the active elements together in groups and holds them in contact with the plate.

Abstract: A photosensitive multi-layer material comprising a base, which may or may not be provided with an adhesion-promoting layer, and a photopolymerizable layer, consisting of a mixture of a photoinitiator, a binder and a photopolymerizable monomer, possesses, between the base and the photopolymerizable layer, an adhesive layer of a hardened mixture of a binder and an etherified melamine-formaldehyde condensate, hardenable at 60.degree.-120.degree. C.

Abstract: A process for the preparation of etherified or non-etherified aminoplast resins, wherein an aminotriazine of the general formula (I) ##STR1## where X is hydrogen, alkyl, phenyl, alkylphenyl or --NH.sub.2, is reacted with a .beta.-hydroxyaldehyde of the general formula (II) ##STR2## where R', R" and R'" are identical or different and each is hydrogen or alkyl, or R" and R'", together with the .alpha.-carbon atom, are a cyclopentane or cyclohexane ring, and R" and/or R'" can be hydroxyalkyl and R" can be phenyl, the reaction being carried out in the presence of not less than one alcohol and an acid catalyst for the preparation of etherified aminoplast resins and in the presence or absence of an acid catalyst for the preparation of non-etherified aminoplast resins. The aminoplast resins prepared according to the invention can be used as surface-coatings raw materials.

Abstract: A photosensitive multi-layer material comprising a base and a photosensitive layer which has a polyamide binder and is soluble or dispersible in an alcoholic solvent contains two layers between the base and the photosensitive layer, namely (a) an adhesion-promoting layer, adjacent to the base, which is derived from a polyurethane binder, prepared by reacting a hydroxyl-containing epoxy resin and a polyisocyanate, and a pigment combination in which a white zinc sulfide pigment is the essential constituent, and (b) an adhesive layer, adjacent to the photosensitive layer, which consists of a baked mixture of an alcohol-soluble copolyamide and a melamine-formaldehyde resin.

Abstract: A pump for fluid media, with an inner pipe or tube arranged in a housing. A drive shaft is journalled in the inner tube, and a rotor is arranged in the housing. The rotor has a main body which is secured to the drive shaft and is provided with conveying blades for the medium. The rotor has a turbine or pump operating counter to the transporting or conveying direction of the conveying blades. At least one passage is arranged in the main body and extends from the pressure side to the suction side of the rotor, with the passage being connected with a suction gap on the inner tube.

Abstract: Disclosed is a linear micrometer which comprises a cylindrically shaped housing, a tube-shaped sleeve displaceably mounted along the longitudinal axis of the housing and extending from one end of the housing, a measurement scale fixedly mounted along the longitudinal axis of the housing and slidingly supported inside the spindle sleeve, and a measurement readout means couple to the spindle sleeve for reading and displaying the relative position of the spindle sleeve to the scale. A rapid adjusting means and fine adjusting means are also provided.
