Abstract: An electrical linkage assembly for a window or door includes a frame mount, a sash mount, a first link arm, and a second link arm. A first pivot joint is formed between the frame mount and the first link arm, a second pivot joint is formed between the first and second link arms, and a third pivot joint is formed between the second link arm and the sash mount. One or more electrical wires extend from the frame mount, through the first and second link arms and each of the first, second, third pivot joints, fully enclosed therein, and out of the sash mount.

Abstract: A process and apparatus are described for extruding a soft, low density elastomeric thermoplastic foam. A single screw extruder having a very large screw length to diameter ratio is provided to thoroughly mix the thermoplastic elastomer with a blowing agent. A thin, substantially taperless die is also provided to form extruded profiles. By using such a process and apparatus, a variety of complex-shaped extruded profiles may be easily produced.

Abstract: A method and apparatus of applying a coating to a substrate is provided. A liquid resin is introduced into a first region at a predetermined pressure. The liquid resin is maintained within a first pressure range in the first region. Next, the flow of the resin from the first region to a second region is controlled so as to bring the resin from the first pressure range to a second pressure range, the pressures in the second pressure range being lower than the pressures in the first pressure range. The liquid resin is then applied at a pressure within the second pressure range to the substrate at a third region adjacent the second region.

Abstract: Weatherstripping is produced continuously by two or more spaced apart tufting heads, which may be operating at different stitch rates. The or each strip of weatherstripping comprises at least two rows of tufts sequentially inserted by two tufting heads. Heated dies may be located between the tufting heads for transforming rows of tufts inserted by the first tufting head at least partially into film to form barrier fins. The knuckles of the tufts are flattened, a secondary backing applied, and then individual strips of weatherstripping separated by ultrasonically slitting, all as a continuous process enabling weatherstripping of various constructions to be efficiently and economically produced by tufting.

Abstract: Standard weather stripping composed of a backing strip and a pile body projecting from one face of the backing strip is guided into a channel having a pair of spaced apart side walls and a bottom wall. Also guided into that channel and positioned against the side of the pile body is an impervious resilient film barrier which extends from the top of the pile body down to the base thereof and across the adjacent side edge margin of the backing strip. The channel side walls are clinched against the bottom wall thereby capturing the weather stripping between those walls and bending the film barrier adjacent the base of the pile body so that the resiliency of the barrier tends to bias the portion of the barrier projecting out of the channel against the pile body so that it remains in an erect position and prevents moisture and drafts from penetrating into the pile body.
