Abstract: A shower head is disclosed of the type having a pivotally mounted spray head. The shower head comprises a first member adapted for attachment to a water supply pipe and a spray head pivotally mounted to the first member. The first member includes a concave, socket-defining surface with a water supply aperture therein. The spray head has an inner spray body, through which the water flows, and an outer retaining sleeve, which secures the spray body to the first member. To prevent leakage between the spray body and the sleeve, an annular seal is carried by the spray body and slidably engages the concave surface of the first member along a line which encloses the water supply aperture at all pivot positions of the spray head. In the preferred embodiment, the inlet end of the spray body defines a flow-limiting vortex chamber, into which water is directed in a swirling action.

Abstract: This is a molding apparatus designed to mold a plastic tub of circular transverse cross-section and re-entrant shape. Specifically, the tub tapers from its closed bottom to its opened top. The mold core is, therefore, collapsed radially to permit extraction of the plastic tub from the mold. This radial collapse is accomplished by forming the mold core of a central segment and a plurality of peripheral segments, and then axially extending the central segment while moving the peripheral segments along a radially inward path so that core collapse occurs. The exterior shape of the peripheral core segments defines a circular cross-sectional shape for the interior of the tub, despite the fact that the central core segment has the configuration of a hexagonal pyramid. Side mold segments which move radially outwardly and a tub extraction ram complete the equipment for extracting the tub from the mold.

Abstract: There is provided a process for producing reconstitutable natural coconut flavor by grinding coconut meat preferably from which the germ eye has been removed, until a pulp of coconut fiber and coconut flavor liquor is obtained. The pulp is separated into the flavor liquor and fiber, wherein the liquor has no more than 2% fiber therein. The liquor is heat treated under enzyme deactivation conditions, whereby any deleterious coconut enzymes in the liquor are deactivated. The liquor is concentrated by condensing the liquor to more than 25% solids or spray drying the liquor to a free-flowing powder. The concentrated coconut flavor may be reconstituted with an aqueous diluent to provide a liquid coconut flavor. The coconut flavor is a mixture of coconut fat and coconut protein/carbohydrate in ratios of 40-72:60-28 and the coconut flavor in the reconstituted form contains no more than 2% coconut fiber.

Abstract: The attachment is primarily used as a replacement for the conventional presser foot typically employed on an industrial sewing machine, and is in particular useful when stitching multiple layer fabrics having synthetic backings. The attachment is for pressing the fabric being stitched against parallel arranged feed dogs and includes a wheel assembly frame supported from one end of a presser arm which is, in turn, pivotally supported at its other end from the machine. The wheel assembly supports a wheel mounted for rotation about a substantially horizontal axis and preferably of a yieldable rubber or rubber-like material that overlies one of the feed dogs of the sewing machine, and a presser foot mounted beside the wheel having a lower pressing surface and overlying a second feed dog of the sewing machine.

Abstract: A cryogenic breathing system comprises a storage container and a portable container. Both containers, include outer casings and inner containers having small connected openings at their top and providing an evacuable space between their outer casings and inner containers. Material to inhibit heat transfer through the evacuable space is included in this space between the outer casings and inner containers of both containers. The openings of both containers are closed with gas-tight closures fastened to their outer casings. The gas-tight closures can carry, through the single openings in the containers, means to withdraw oxygen for breathing, liquid level indicating means and a mechanical structure to protect the liquid level indicating means, means to admit or withdraw liquid oxygen from the inner container, and means to admit heat to the inner container, as may be desired.

Abstract: A process for preparing linear polycarbonates containing terminal hydroxyl groups with the essential exclusion of other terminal groups by reacting glycols having a carbon number > 4 and cyclic esters of carbonic acid via ester interchange reaction at 100-300.degree. C and 0.1 - 300 mm Hg.

Abstract: Seamless flooring comprising layers of an acrylic polymer applied from a latex including one or more layers of intermediate plastic chips, the method of making the same, and film-forming latex compositions for making the same consisting of an aqueous emulsion of a methacrylic polymer in combination with a solvent.

Abstract: An improved mechanical cork puller wherein the pivot holes of the lever arms receive and pivot about one or more ribs formed on the inner surfaces of the opposed pairs of support ears, resulting in no visible sign of a pivot support on the outer surfaces of the support ears. The support ears have an inwardly diverging taper providing free meshing movement between the toothed sectors of the lever arms and the cork puller shaft. To manufacture, elongated rib members are initially die-cast on the inner surfaces of the support ears and thereafter cut away to the desired length to form the pivot support for the lever arms. As cast, the inner surfaces of the support ears diverge outwardly and thereafter the outer ends of the support ears are bent toward each other so that the inner surfaces thereof diverge inwardly. The lever arms are thereafter assembled by merely forcing fitting them into place between the support ears.

Abstract: A construction suitable for incorporation into a display device, reflector, or the like. The construction employs a closed loop of material having elongated side wall portions. The loop is generally cross sectionally H-shaped. A flange or the like may project laterally outwardly from one side wall portion of the loop. A pair of plates are provided, each plate having a groove formed about the perimeter of the inner surface thereof and being adapted to nest matingly in a different lateral opposed side face defined by the loop. The plates are directly interconnected together when rested in the loop and interlock over the inside legs of the loop.

Abstract: A protective housing or junction box formed of a fireproof or fire resistant material which receives and houses therewithin the spliced ends of electrical conducting wires. The housing is positioned within the base of a lamp.

Abstract: A valve actuator comprising a toggle mechanism and push rod operable to effect opening and closing of the valve by repeatedly pushing the push rod.
