Abstract: Stranding apparatus for fabricating open-weave structures includes a base frame supporting a pair of spaced apart plates, both of which plates includes a plurality of movable pins on which resin impregnated, continuous filament strands are placed. The pins retract into the plates after the resin has cured to allow the stranded product to be removed from the frame. The apparatus rotates about a central axis to provide a plurality of stations at which a specific process or step is accomplished.

Abstract: Very compact resin mixing and delivery device for use in mixing and delivering such resin as urea formaldehyde with foaming agents or the like and for delivering such mixtures to a delivery conduit which is adapted for applying the resin and foaming agent in place so that it may develop into a cured cellular foam like hard filler or body for use in various applications such as building insulation, wall reinforcing and filling various voids or cavities in a great variety of structures.

Abstract: A hand held sealer compresses and welds tubing intermediate a pair of jaws, which jaws also serve as the plates of a variable capacitor of an Rf resonant circuit. The flow of power intermediate the jaws generating the heat applied to accomplish the weld is a function of the spacing of the jaws, whereby the applied power is regulated to weld but not destructively melt the tubing.

Abstract: The disclosure relates to a cutting machine and more particularly to a cutting machine for cutting off short lengths of elongated material such as circular in cross section wire-like or tubular elements and more particularly to material commonly known as liquid silver which is small diameter tubular silver elements used to make necklaces or the like. The machine comprises a means for feeding intermittently a plurality of elongated work pieces in parallel relationship to each other and for sequencially and intermittently operating a circular saw which moves laterally relative to the work pieces and cuts off short lengths thereof. The machine comprises means for automatically sequencing the feed means and the cut-off means in timed relation to each other and such that, as for example, as many as 30,000 to 70,000 pieces may be cut in 1 hour's time.
