Abstract: A PLUG-IN TERMINAL            Abstract of the Disclosure A plug-in terminal for connecting a stranded insulated conductor with a conductive path on a circuit hoard includes a barrel of ductile metal for receiving a stripped end of the conductor.  The barrel has a first section at a first end thereof for gripping the insulation on the conductor adjacent the stripped end, a second open-ended section at a second and opposite end thereof for surrounding and loosely gripping the strands at the extremity of the stripped end, and a third section, between the first and the second sections, for surrounding and tightly gripping the strands.  After being crimped onto the conductor, the terminal is extended through a hole formed through the circuit board and the conductive path thereon.  Locating and locking tabs extend from the terminal to position the ter-minal within the hole with the second section projecting beyond the conductive path, and to then secure the terminal within the hole.  Solder applied over the second section and the conductive path enters, as a result of the strands being loosely gripped within the second section, within the open end of the second section and around the strands to effect a secure electrical and mechanical connection between the terminal, the strands, and the path.

Abstract: ABSTRACT OF THE DISCLOSURE A blood collection device includes a tube for receiving a sample of whole blood for centrifugal separation into the lighter phase, plasma or serum, and the heavier cellular phase.  The tube has a needle-pierceable stopper at one end for maintaining a negative pressure in the tube.  A blood phase partitioning device is disposed within the tube and includes an upper cylinder member and a lower piston member slidable in the upper member.  The cylindrical member has a plurality of peripheral holes therein and a specific gravity greater than that of the piston member, with the members together having a specific gravity between that of the lighter phase and that of the heavier phase.  A sealant is disposed within and in direct contact with the cylindrical member and has a specific gravity substantially equal to that of the two members together.  During centrifugation of the blood, the partitioning device automatically moves to the interface of the two phases, and the members move relative to each other forcing the sealant radially outwardly through the peripheral holes in the cylindrical member and against the inner wall of the tube to provide a permanent partition between the two separated phases.

Abstract: Abstract A method is disclosed for terminating a cable composed of a multiplicity of wires each preformed with a helical twist.  The method includes the steps of:  feeding an end portion of the cable to be terminated through a sleeve, gripping the cable at a selected point near the end portion thereof to be terminated; unlaying the end portion of the cable with a minimum of distortion of each unlaid wire from the laid shape so that each outermost cable wire resumes its preformed helical twist about an axis that is different from those of the other wires whereby the wires in said portion together form an envelope that is symmetrical about the cable portion axis and has a circumferential bulge adjacent its inner end, a circumferential flare at its outer end and a circumferential constriction intermediate its ends.  The sleeve has a tapered bore whose length and whose major and minor diameters are related to the envelope dimensions so that when the end por-tion is pulled back into the sleeve with the envelope axis aligned with the bore axis the envelope bulge is positioned adjacent the smaller end of the bore, the envelope flare is positioned adjacent the larger end of the bore, and the flaring wire ends lie against and are distributed around the bore wall.  The cable end portion is arranged inside the sleeve bore so that the envelope axis substantially coincides with the bore axis.  The sleeve bore is filled with a settable material so that it surrounds the unlaid wires, forming a solid tapered plug extending both inside and outside the entire length of the envelope formed by those wires that will wedge against the bore wall when a tensile force is applied between the sleeve and the cable.

OSWALD                    ABSTRACT OF THE DISCLOSURE           Continuous filaments, e.g. in the form of yarn, are fed by aspiration into a stream of heated fluid.  The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments.  A major portion of the fluid is separated from the filaments and expelled from the chamber.  The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the fila-ments, whereby the filaments are forced against a mass thereof producing crimps therein.  One or more streams of heated fluid are then contacted with the mass of filaments to set the crimps.          The crimped filaments emerge from the chamber through an outlet opening therein.

Abstract: ABSTRACT OF THE DISCLOSURE        A pizza crust has a surface for receiving food in-gredients such as sauce, cheese and the like.  An aqueous dis-persion containing water-soluble algin is applied to the food ingredient receiving surface.  An aqueous gelling solution is applied to the algin-coated pizza crust for a period of time sufficient to form a substantially continuous edible algin-containing film along the food ingredient receiving surface. The film is sufficient to effectively retard the migration of material from food ingredients placed on the food ingredient receiving surface.  A second algin-containing film is formed over the ingredients in the same manner as the first film was formed on the pizza crust.  The algin-containing film used with the pizza is sufficient to retard dehydration from both the pizza crust and the food ingredients.  The film is effective to reduce breaking and splitting of the pizza to improve the trans-portabillty thereof.  The film is sufficient to constitute an oxygen barrier for retarding oxidation to prevent ingredients highly susceptible to oxidation from becoming rancid.  The film is sufficient to hold the food ingredients physically in place on the pizza crust while the pizza is subjected to subsequent processing steps.  Finally, the film is sufficient to retain flavors within the pizza during cooking thereof.
