Abstract: A method and apparatus for producing a continuous web of material (36) on an endless belt (24). Fibers suspended in a carrier gas are transported from a transport conduit (12) through a transition part (38) of zig-zag configuration, having cross-section which tapers or narrows in the flow direction. Arranged at the outlet aperture of the transition part is a coarse-particle separator means (22) which incorporates a curved, convex surface (60), an accept outlet (48), and a reject outlet (54). The carrier gas is deflected around the convex surface, as a result of the ensuing Coanda Effect, and transports acceptable fine fibers to the accept outlet (48), while coarse reject particles, due to their greater kinetic energy, pass in a straighter path to the reject outlet (54). The accept outlet leads directly to a distribution chamber (52) which is located above the endless belt (24), and opposite which there is provided a suction box (32) for extraction of the carrier gas.

Abstract: Yarn to be utilized for the manufacture of pre-softened fabric is stiffened without the use of binding agents. Only corn starch and low temperature wax are utilized as stiffeners. Fabric manufactured from such yarn is then subjected to a finishing process, in which enzymes capable of breaking down the corn starch and a wetter/rewetter are added to the fabric itself. These enzymes are activated during a subsequent soaking in water only, followed by agitation, whereby stiffness may be removed from the fabric in approximately 5 minutes. In accordance with another aspect of the invention, softeners are also added to the fabric during the finishing process. The softeners are also released during the subsequent garment washing operation. Preferably, the softeners include at least reactive silicon. This serves the additional purpose of lubricating sewing needles and cutting knives during the garment manufacturing process.

Abstract: A major difficulty with fabricating GaAs digital logic circuits using enhancement-mode MESFETs has been the large gate-source and gate-drain parasitic resistances inherent in conventional designs. A self-aligned gate process is presented, which incorporates a "mushroom" gate structure for self-aligning both an n+ implant and the source/drain contacts to the gate, thus minimizing the parasitic resistances. The "mushroom" gate consists of a two-layer TiW/Si metallization in which the bottom TiW layer is undercut with a closely controllable chemical etch. The process is compatible with the high temperature anneal necessary to activate ion-implanted GaAs.
