Abstract:
Apparatus for applying an asphalt binder composition to a roadway during construction or repair of an asphalt pavement which apparatus include: a mobile vehicle having a chassis (1) extending in a longitudinal direction which longitudinal direction is aligned with a forward/rearward direction of travel of said mobile vehicle; at least one storage tank (4) supported on the chassis containing an asphalt binder composition; and at least one spray nozzle (6) configured to dispense the asphalt binder composition from the at least one storage tank in a longitudinal strip or band (7) having a width that is no greater that a width of the asphalt binder composition dispensed by one of the at least one spray nozzle. The at least one spray nozzle can include a plurality of spray nozzles that are coupled to a common spray bar. The asphalt binder composition may be a void reducing asphalt membrane composition that is provided between adjacent asphalt pavement passes.
Abstract:
The invention relates to an apparatus for treating sheet-like material, in particular panels, film or foil, wherein the apparatus has at least one bar-like or rod-like strip arranged transversely to the longitudinal direction of the sheet-like material, wherein the sheet-like material is moved longitudinally past the strip, wherein the strip consists of porous, fluid-permeable metal foam, at least over a part of its outer surface which is directed towards the sheet-like material, and wherein means are provided for feeding a treatment fluid through the metal foam in the direction of the sheet-like material.
Abstract:
Coating a stent may include continuously rotating the stent in one direction while spraying a first coating layer followed by continuously rotating the stent in another direction while spraying a second coating layer, wherein the first layer is preferentially distributed over a side surface of the stent struts and the second layer is preferentially distributed over an opposite side surface of the stent struts. The overall coating distribution combining both layers may be evenly distributed over the two side surfaces of the stent struts.
Abstract:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Strahlungshärten wobei zumindest eine Einrichtung zum Beaufschlagen eines Werkstückes mit Strahlung vorhanden ist und zudem eine Zuleitung für Kühlmittel und eine Ableitung für Kühlmittel vorhanden ist, welches in der Einrichtung entstehende Wärme aufnimmt und abführt und eine Kühleinrichtung zum Kühlen des erwärmten Kühlmittels vorhanden ist. Zudem wird Inertgas über eine Zuleitung der Einrichtung zum Strahlungshärten zugeleitet wird, wobei das Inertgas in einer Verdampfungseinrichtung aus dem flüssigen in den gasförmigen Zustand überführt wird, wobei zumindest ein Teil des flüssigen Inertgases über einen Wärmetauscher (15) geführt wird, in den das aufgewärmte Kühlmittel eintritt. Die Verdampfung des Inertgases entzieht dem Kühlmittel Wärme.

Abstract:
Polymer particles containing a polyoxymethylene polymer for coating metallic substrates are described. The polymeric particles contain a polyoxymethylene polymer in combination with an adhesion promoter which may comprise an acid modified polyolefin and performance enhancing additives. The polyoxymethylene polymer and the adhesion promoter may also be combined with a thermoplastic elastomer and optionally a coupling agent. Also disclosed is a process where the polymeric particles are used to from a fluidized bed for coating metallic substrates. In one embodiment, after being coated with the polymer particles, the coated metal substrate is gas cooled followed by cooling the coated substrate in a bath containing an aqueous medium.

Abstract:
The present invention is directed to a method for coating a surface of a medical device with a coating composition. The method involves chilling the surface to be coated to below the freezing point of at least one solvent contained in the composition. This coating composition is applied to the chilled surface, and a portion of the coating composition is allowed to freeze onto the surface. The surface can then be heated (either by the application of heat from an external source, by allowing to heat by ambient air) to above the freezing point of the solvent in the coating composition to allow the solvent to thaw and be removed, thereby forming a smooth, uniform coating on the surface of the medical device.
