Abstract: A method for forming a laminated synthetic leather includes engaging a textile carrier onto a carrying roll, extruding one or more materials with an extruder machine into a film, and feeding the film downwardly onto a lamination roll to have the film carried on a portion of an outer peripheral portion of the lamination roll and to have the film to be suitably cooled by the lamination roll. The film and the textile carrier are then compressed together with the rolls, to form the laminated synthetic leather, and to prevent the film from penetrating into the textile carrier to a greater extent, and to form a soft or flexible laminated synthetic leather.

Abstract: An etching monitoring apparatus and related method for use in the manufacture of microstructures (and in particular MEMS) located within an etching chamber is described. The apparatus and related method operates by setting the temperature of the chamber within which the microstructure is located at a starting temperature, and maintaining the partial pressure of an etching gas within the chamber at a constant value. As a result the surface temperature of the micro structure within the chamber is primarily determined by the etch rate. Therefore, by employing a thermometer to monitor the change in etching surface temperature, a direct diagnostic for monitoring the etching process is provided.

Abstract: An extrusion product or profile is formed by extrusion of a cellular compound to form a base and then subsequent extrusion of a non-cellular compound to form an attached flexible strip. The final product or profile is used as a garage door weatherstrip in which the cellular base is mounted against the door jamb and the strip of flexible non-cellular material extends out from the cellular base to prevent the flow of air through openings between doors and adjacent jambs or frames. The process for forming such a product involves sequential extrusion of the two portions of the product. First, a cellular base is extruded through a die and vacuum sizer and allowed to cool. Next, a saddle die is used to apply the flexible non-cellular strip to a portion of the cellular base.
