摘要:
A transparent pane, in particular a glass pane, having at least one electroconducting, non-transparent contact surface placed on one of its surfaces, to connect it by soldering to a connection piece. In the region of the soldering location, the contact surface has at least one cutout via which the soldering filler metal is visible through the pane after the connection piece has been soldered to the contact surface. Such a configuration allows reliable visual verification of the soldering locations, even in cases in which the soldering location is incorporated within a composite glazing panel and has been soldered, if necessary by induction heating.
摘要:
A method for transporting a fixed glazing to be equipped with a coating, particularly a curved glazing, through a coating plant. The glazing is transported by a transport device through the plant such that one of its main sides is covered with protection against the coating substance that is to be deposited. The side of the glazing that is to be protected when the coating is being deposited is kept in contact with a flexible fabric attached to the transport device.
摘要:
A coating process for an apparatus for applying plastic coatings onto a planar substrate which includes an elongate coating head defining therein an elongate distribution channel having a length corresponding to a width of a substrate to be coated, the coating head also defining a coating gap for discharging a coating material from the distribution channel. First and second supply channels are respectively connected between respective pumps and different portions of the distribution channel for respectively supplying first and second coating materials to the distribution channel. A mixing zone is formed in the distribution channel by a partition or a hollow conical body, each of which forms a mixing gradient extending along the length of the mixing zone. Ideally, the pumps for the first and second coating materials provide these materials with the same pressure within the mixing zone.
摘要:
A method and apparatus are disclosed for covering the face of a blank of mineral or organic glass with a protective plastic film. Before pressing the protective film onto the surface of the blank, the blank and film are positioned a certain distance from each other by means of separate holding devices and held so that the edge of the blank and the film do not touch. The film is then heated so that the center of the film surface attains a higher temperature than the outer edge. Pneumatic pressure is then applied to the film surface so that more pressure is exerted at the center of the film than at the outer edge. The protective film is forced on to the surface of the blank from the center radially outward by the applied air pressure, forcing gas trapped between the block and the film to escape from between the blank and the film toward the outer edge of the film as the film makes contact with the blank. Finally, additional pressure is applied to the film to complete the bonding of the film to the blank.

摘要:
A process and apparatus for producing a homogeneous and highly transparent sheet or film from a mixture of a plurality of components which comprises mixing the combined reaction components and depositing the reaction mixture on a molding substrate where the reaction is carried out in a layer thereon, wherein the combined reaction components are mixed, first, in a static mixer and, immediately thereafter, in a dynamic mixer.The invention can be advantageously applied to the manufacture of polyurethane sheets which can be employed in laminated glass sheets.

摘要:
A heated window with an electrically conducting surface coating that may be electrically connected as a heating element to a voltage source using a first and a second current-collecting rail and that is split into a first part, a heated look-through region, and a second part, an additional heated region. In the heated window at least two current-collecting rails are arranged in the additional heated region so that the direction in which the current flows in the additional heated region is roughly perpendicular to the direction in which the current flows in the heated look-through region.
