Abstract: Transparent organoplastic apparatus is described having at least one capillary chamber formed therein communicating with an outer edge of the apparatus. This chamber has a flat bottom wall and a flat upper wall forming the capillary chamber therebetween. The upper wall has an outer edge extending inwardly in a concave fashion from the outer edge of the apparatus, exposing the portion of the bottom wall between the outer edge of the upper wall and the outer edge of the apparatus. Liquid to be inspected is placed on this exposed portion of the bottom wall at the concave outer edge of the upper wall, and capillary action draws such liquid into the capillary chamber where it can be microscopically examined.

Abstract: A semi-unitary protein product consisting essentially of a bundle of intermittently fused parallel protein fibers which closely resembles the fibrous structure of natural meat can be prepared by heating a protein-water mixture to form an extrudable plastic mass and then extruding the mass under pressure through a spinneret having a plurality of closely-spaced orifices therein directly into a gaseous medium to yield the desired product.
