Abstract: A method and apparatus for binding the fibers of a fiber reinforced plastic preform.  A fiber reinforced plastic preform is created in a preselected geometry from a mixture of reinforcing fibers and binding material.  The fiber reinforced plastic preform is sequentially exposed to high temperature steam and cool air causing the binding material first to melt and, thereafter, to solidify thus binding and locking the reinforcing fibers of the preform in place.  The fiber reinforced plastic preform is ejected from the apparatus by air pressure and is retrieved by any suitable method.

Abstract: The present invention provides a method of making a tensioned focus mask, which includes a set of parallel strands and a set of parallel wires that are perpendicular to the strands and separated from the strands by insulator means. The method includes attaching the strands to a mask frame and then coating the strands with a first insulator. The first insulator is then cured, and a second insulator is applied to the first insulator. Next, wires are wound over and in contact with the second insulator, by rotating the mask frame and by drawing a continuous wire from a source through a tensioner, while guiding the continuous wire into desired positions overlying the strands. Finally, the second insulator is heated until the wires attach to the second insulator.

Abstract: A roll-up crowd gate comprises an electrically charged drum that is rotatable in a carriage.  Long cables connected to the drum are also electrically charged.  A rope translates the carriage in tracks between upstream and downstream locations.  Translation of the carriage in the downstream direction when the cables are unrolled from the drum urges a first herd of cows to the downstream location.  Carriage stops in the tracks stop carriage translation at the downstream location, but continued operation of the rope when the carriage is against the stop causes the drum to roll up the cables.          Reverse operation of the rope translates the carriage above the first herd to the upstream location.  A carriage stop at the upstream location stops carriage translation, but continued operation of the rope rotates the drum and unrolls the cables behind a second herd of cows.
