  • Patent number: 5685662
    Abstract: Connection of two longitudinal sections (10, 22) that are at an angle to each other, each longitudinal section (10, 22) having two connecting sides (12) and two wall sides (14), where at least one connecting side (12) of each section (10, 22) exhibits a groove (24) that is undercut on both sides and on both sides of the undercut groove (24) an integral longitudinal flange (30). The first longitudinal section (10) exhibits a transversely cut section face, the end face (16) of the first longitudinal section (10) which is secured at an angle to a connecting side (12) of the second longitudinal section (22). The first longitudinal section (10) exhibits a recess (18) at its end (16) in which a connecting element (60), introduced into the groove-like recess (34) between the longitudinal flanges (30) in the second longitudinal section (22), engages--as a result of which the connecting element (60) forms a mechanical joint by virtue of fit with the end recess (10).

  • Patent number: 5640872
    Abstract: In a process for cooling hot rolled metal plates (16) and strips, especially such of aluminium or an aluminium alloy, a hot rolled strip (12) is cut to plates (16) immediately after it emerges from a rolling mill (10). Immediately after the cutting to length, the plates (16) pass through a cooling station (20) where they are jetted directly with water from flat stream nozzles (52). The water stream (W) emerging from the flat stream nozzles (52) form essentially a plane (E) which is directed at the plate surface (32). Immediately after it leaves the flat stream nozzle (52), the water stream (W) is periodically deflected by means of streams (A, B) of air or water in such a manner that the water stream (W) striking the plate surface (32) performs a wiping action.

  • Patent number: 5582863
    Abstract: A process for forming a reflective surface, comprises the steps of: providing at least a part of at least one unanodized surface which has a peak-to-valley height Ra of equal to or less than 1 micron. The unanodized surface is selected from the group consisting of (1) refined aluminum with a degree of purity equal to or greater than 98.3% by weight aluminum and (2) aluminum alloys with at least one element selected from the group consisting of Si, Mg, Mn, Cu, Zn, Fe. The unanodized surface is in a form selected from the group consisting of rolled foil, rolled sheets, and rolled strips and said unanodized surface is used as a substrate. The process further includes depositing at least two layers from the gas phase on the unanodized surface, wherein the two layers include a ceramic adhesive layer from the gas phase and at least one reflecting layer from the gas phase on said adhesive layer for the reflection of radiation with wavelengths in the optical range.

  • Patent number: 5580386
    Abstract: A substrate surface is coated with a permeation barrier of inorganic material, which is vaporised from a crucible in a vacuum chamber evacuated to at least 10.sup.-3 mbar and precipitated on the substrate surface. An ionizing electron beam of low energy is thus passed through the gas phase of inorganic material with formation of a plasma, preferably in the direction running approximately parallel to the substrate surface. At least one low voltage electron beam gun with assigned electrode is incorporated in the vacuum chamber between the crucible and the substrate support. The main application is for coating plastic films for the packaging industry.

  • Patent number: 5478424
    Abstract: A process for joining components made of metal, in particular aluminum and aluminum alloys, is such that a thermally-curable (hardenable) adhesive is deposited between the close-fitting surfaces of the components that are to be joined, and one of the outer surfaces neighboring the said close-fitting surface of one of the components is radiated with infra-red radiation in order to cure the adhesive. At least the outer surface to be radiated is provided with a pattern that roughens that surface. By reducing the reflectivity of the roughened surface the capacity to absorb infrared radiation is increased. A preferred application for the process is in the adhesive bonding of shaped parts, especially body sheet in automobile manufacture.

  • Patent number: 5413314
    Abstract: The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections in particular sections of aluminum or an aluminum alloy from all sides. The cooling medium emerges from spray nozzles program-controlled in the direction of the section. The distance, the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribution of mass in the section. The optimum parameters are determined and stored in the unit processor. The spray nozzles are arranged in nozzle beams running in the direction of the extruded section. The nozzle beams comprise at least one longitudinal water channel and two longitudinal air channels, whereby cross-intersecting channels branch off from the water channels to the spray nozzles and the air channels terminate in air gaps which are directed towards the nozzle outlets.

  • Patent number: 5403424
    Abstract: The invention relates to a process for protecting sensitive surfaces from mechanical and physical effects, in particular the effects of pressure and/or heat, whereby the surfaces are covered by a protective layer during the application of pressure and/or heat. The protective layer is a thermoplastic or elastic plastic that is molten, plastic or elastic under the conditions of applied pressure and/or heat, and has a lower resistance to deformation than the surface to be protected.
