Abstract: A gazania plant characterized by blossoms which are orange, with orange and black stripes.

Abstract: Carboxylic acid terminated diamides and alkali metal, ammonium or amine salts thereof are provided which are derived from the reaction of organic polycarboxylic acids and polyoxyalkylene diamines. The diamides have lubricating properties and are especially useful in aqueous metal working fluids.

Abstract: 2-Hydroxymethyl-3,4,5-trihydroxypiperidine possesses antidiabetic and lipid biosynthesis inhibitory properties. The use of the compound for such indications and pharmaceutical compositions adapted to this use are described.

Abstract: Flame retardant polyurethane foams are prepared from compositions containing as flame retardant additives, a select group of halogenated phosphate esters.

Abstract: 3-(2-pyridyl)-5,6-bis(phenylsulfonic acid)-1,2,4-triazine and certain salts thereof, e.g.--sodium, are provided together with a method for forming such compounds. These compounds are useful as reagents in the spectrophotometric determination of iron in water or other solutions.

Abstract: A shoulder pad for football players comprising a left-hand member which fits over the left shoulder and a right-hand member which fits over the right shoulder. Each of the members is a relatively rigid member of generally inverted U-shape as viewed from the side and has a chestplate portion, a backplate portion and an arch integrally connecting the plate portions. Each member has padding on the inside thereof with the padding at the top of the arch overlying the shoulder. A pair of caps of relatively rigid material fit over the outer part of the shoulders and have shoulder padding on the inside thereof separate from the arch padding. The shoulder padding is hinged to the arch padding for enabling the shoulder padding to swing upwardly relative to the arch padding.

Abstract: The apparel is an uninsulated vest having insulated arms and adapted to be worn underneath a sleeveless insulated jacket.

Abstract: A drain clearing device which effectively employs water pressure to clear a blocked drain where the drain opening is submerged or relatively inaccessible. The drain clearing device comprises a drain sealing member of resiliently compressible material attached to a water supply device having an elongated pipe with a side arm for coupling to a water hose. A plunger valve is mounted in an end of the pipe remote from the sealing member and when activated allows water pressure to clear the blocked drain.

Abstract: Disclosed is a discharge drain assembly (for use in a sink) including a drain body and a plug assembly adapted to fit in the drain body which features limited rotational movement between an open and a closed position. The plug includes a stainless steel strainer with an integral hollow knob having opposed sides which are inwardly concave. The knob securely but releasably retains a slotted head portion of a spindle. The spindle has a neck portion for receiving a sealing washer and a lower body portion including three leg portions. The leg portions support the plug in the open position, restrain rotation in a first direction beyond the open position, and cam the plug to the closed position when rotated in a direction opposite said first direction. The structure substantially eliminates a "finding" problem common in prior art arrangements and provides a good seal in the closed position.

Abstract: A venturi type mixer that produces an aerated water jet for spas, therapy pools, swimming pools and the like, is provided with a pulsating action by means of a flow impeding spoiler that momentarily and repetitively disturbs the water jet that is projected into the mixing chamber. Disturbance of the jet effectively disables the vacuum produced by the venturi action to thereby cause discharge of a water stream of decreased velocity having considerably less entrained air. The spoiler is moved into and out of the water jet by means of an automatically reciprocating piston that is operated by a combination of a spring and the vacuum produced by the venturi action. Alternatively the spoiler may be rotated into and out of the path of the jet by a water driven rotor, or the jet orifice may be rotated relative to a fixed spoiler.

Abstract: A portable, suspended outdoor shelter includes a base panel having a pair of stiffening members secured in a pair of sleeves disposed along opposed longitudinally extending sides of the base panel. A pair of reinforcing web members extend along and reinforce the sleeves, and extend substantially therebeyond to be secured to a pair of spaced apart support structures such as adjacent tree trunks or boughs. A plurality of resilient, linear tubular members are bent in inverted U configuration and are secured above and between the stiffening members to apply tension laterally to said base panel. End panels extend between the ends of the base panel and the lower portions of their respective reinforcing web members, with a window and a door disposed in the end panels. A canopy extends between the upper edges of the end panels, and is supported by the inverted U tubular members.

Abstract: A medical pillow providing stabilized support for the head and neck of the user and incorporating a convoluted upper surface is disclosed. The pillow is typically rectangular and has a generally flat bottom and a contoured top. The contoured top has a central depression for placement of the user's head therein and a neck supporting depression area extending between the head supporting depression and one side of the pillow. The head and neck depression areas are curved to conform to the curvature of the user's head and neck. The surface of the top is convoluted to provide more uniform vertical support and improved lateral support for the head and neck.

Abstract: A hand held tool for installing a threaded fastener in which the tool is adapted for use solely as a drill bit, solely as a screwdriver, and as a combination thereof, wherein the threaded fastener has a central bore extending therethrough. Extension of the drill bit beyond the end of the screwdriver blade may be selectively controlled, and the drill bit may be maintained in its entirety within the shaft of the screwdriver when not in use to thereby preserve the sharpness of the drill bit. A unique locking collar is also provided.

Abstract: A single anchor leg mooring (SALM) installation which enables replacement of a product distribution unit (PDU) without removal of the upper buoyancy structure, including a plurality of arms that can extend around the PDU to connect the buoyancy structure lying above the PDU with a lower structure that lies below the PDU and extends to the sea floor. The transference of oil or other cargo can continue during the replacement of a malfunctioning PDU, by providing a pair of PDUs and a pair of valves for bypassing one of them which is to be removed.

Abstract: A surfboard with a fin is developed to counteract the tendency for skegs or fins to "pop out" especially when the surfer "walks the nose" of the surfboard or rides high on a wave. The fin has a pair of opposed wing hydrofoils extending laterally from an approximately mid-point position on a vertical hydrofoil having a forwardly arcuate relieved portion above the wing hydrofoils, a downwardly-rearwardly swept leading edge and a rearwardly-upwardly swept trailing edge terminating at the confluence of the rear edges of the wing hydrofoils.

Abstract: A punch and binding machine binds material into a booklet with a plastic comb-binding in one continuous operation. The machine combines a conventional multiple hole punch with a uniquely designed binder. A conveyor system moves the material first to the punch machine and then to the comb-binder where an auxillary conveyer moves the material into an opened comb-binding so that the extended fingers of the comb-binding may be released to bind the material into a booklet.
