Abstract: ABSTRACT OF THE DISCLOSURE     A semi-moist, semi-soft, shelf-stable and non-bleeding particle for carrying a food flavor contains 5-30% protein, 5-70% gelatinized starch, 5-40% vegetable fat and at least one of 5-50% dextrose and 5-50% sucrose.          The moisture content is between 2 and 30%.  The particles may be flavored with natural and artifical fruit flavors, cheese flavors, etc.  The texture, mouth feel and flavors closely approximate the natural corresponding particles.          The particles may be used in various conventional food compositions such as dry muffin and cake mixes.

Abstract: IMPROVED COMPRESSED-GAS CIRCUIT-INTERRUPTERS OF THE PUFFER-TYPE HAVING IMPROVED SUPPORTING, SHIELDING AND ASSEMBLY FEATURES            ABSTRACT OF THE DISCLOSURE         An improved compressed-gas puffer-type circuit-interrupter is provided having improved supporting, shield-ing and assembly features for making ready provision for a separate bench subassembly of the gas-interrupter module, and enabling its ready application to a grounded metallic tank-type of circuit-interrupter, or, alternatively, to gas-insulated transmission-line equipment, as desired.         Improved supporting features involve the utiliza-tion of a pair of upstanding side-insulating supporting shields, which substantially solely support the upper rela-tively-stationary contact and shielding assembly, apart from any support needed by the upper terminal-bushing, when used.          Additionally, the invention comprises improved rod guiding features for the movable operating cylinder, improved shield-ing structure on both the stationary and movable contact structures and improved capacitor-tube mounting-assembly arrangements, an improved lower metallic base-support, having a shielding portion, which shields the relatively-sharp-cornered hardware features, such as the movable-contact guiding stem, reducing the electrical gradient, employing tubular shielding structures adjacent the central heavy supporting plate for relieving the electrostatic field, and employing, additionally, an improved upper electrostatic shielding arrangement, easily attached and disassembled by a simplified spring-clip assembly.         An additional feature of the invention is the use of a spherical bearing located at the upper end of the insulating pull-rod assembly, or operating-rod assembly to compensate for inaccuracies in manufacture, and improving the general assembly features adapting the modules for bench-assembly inspection.

Abstract: Abstract of the Disclosure A dispenser for one or more rolls of pressure sensitive adhesive coated tape.  The dispenser includes a core support having an arcuate surface adapted to support the rolls of tape for rotation about the surface.  The core support is fixed at one end to a radially projecting slide.  The slide and a base of the dispenser have interacting portions slidably mounting the slide on the base to prevent rotation of the core support relative to the base and to restrict separation of the core support from the base.  By manually pulling the core support and slide may be moved together upwardly relative to the base to a position at which the core support and slide can be pivoted laterally about projections on the lower portion of the slide. This is the load position at which the empty core can be removed and a full roll applied over an unrestricted end of the core support.  When the full roll, core support and slide are pivoted and pushed downwardly the normal dispense position is reached.

Abstract: Abstract of the Disclosure A method for filling containers with "sundae-style" yogurt includes the steps of placing a transparent lid over the top of a container, and providing an opening in the bottom of the closed, empty container.  The container is inverted to position the lid at the bottom of the container, with the opening being foremost.          A fruit fraction is introduced through the opening to form a layer of fruit preserves overlying the inside surface of the lid.          The remainder of the container is filled with a bacteriologically inoculated, gum stabilized liquid milk fraction introduced through the opening.  The opening is then sealed, and the con-tents of the filled inverted container are incubated so that fermentation of the liquid milk fraction produces yogurt.  The yogurt in the inverted container is refrigerated to solidify the stabilizers in the yogurt.  The container is then positioned in the upright position, providing a container of yogurt with gel strength to support the more dense top layer of fruit pre-serves.  Alternatively, a container in an upright position is partially filled with an inoculated, gum stabilized liquid milk fraction which is then incubated and subsequently refrigerated in a sterile environment to produce gum stabilized yogurt.  A layer of fruit preserves is then added to the top of the yogurt which has sufficient gel strength to support it.  A lid is then applied to the container, providing sundae-style yogurt having a fruit preserve topping immediately inside the lid.  Techniques are also disclosed for inhibiting intermingling of fruit pre-serves with the liquid milk or yogurt fraction by providing a water insoluble, semi-solid edible barrier of hydrogenated animal fat or hydrogenated vegetable oil at the interface between the fruit preserves and the liquid milk or yogurt fraction.

The ring-shaped glass member is formed and fused to the edge of the body of semiconductor material by placing the fusion and a prefabri-cated glass ring, preferably cut from stress relieved glass tubing, encircling the fusion in a furnace.  A weight is applied to the upper surface of the prefabricated glass ring.  An atmosphere comprising a predetermined mixture of nitrogen and water vapor is established in the fusion fur-nace and the temperature of the fusion furnace is increased and decreased in accordance with a predetermined program to cause the prefabricated glass ring to soften and fuse to the edge surface of the body of semiconductor material to form a protective layer, comprising the ring-shaped glass member, overlying the PN junction.
