Abstract: A device for the gravity transfer of viscous flowable materials between a pair of partly filled closed containers disposed one above the other comprising a generally cylindrical connector body having opposed tapered ends for stopper-like insertion into the pour openings of said containers and having a non-clogging air vent tube therein which is of a length to extend upwardly into fluid communication with the air pocket above the level of the contents of the partly filled upper container, the lower end of the vent tube terminating in a widened and sharp-edged air entrance opening.

Abstract: A plastic hinge comprising a leaf having a knuckle extending the length of the leaf, and partially open, with a boss therein positioned substantially medially of the ends of the knuckle, and an elongated pin therein terminating in a right angled arm, said pin having an annular groove therein arranged to cooperate with the detent in the knuckle.

Abstract: A modular refuse compactor having a shiftable rear compacting platen mounted at the lower end of an electro-hydraulic operated cylinder piston rod, and camming means to shift a folded front compacting platen from a vertical position to a horizontal position during downward movement of the rear platen and retain it in said horizontal position as an extension of said rear platen on the compacting cycle, and return it to the vertical position upon the retraction of the rear compacting platen, and appropriate cams and followers to effect such action.

Abstract: A device for removing and replacing a filter screen in a whirlpool apparatus wherein the filter screen is supported on a ledge in the lower end of the apparatus, the stem of the device both carrying the filter and anchored through an aperture in the hub of the whirlpool apparatus in the usual way and the lower face of the screen being provided with equi-spaced arms, the ends of which terminate in apertures in the skirt of the apparatus to support the screen.

Abstract: A leaf-spring supported, free-floating rocker undercarriage for a swivel chair wherein the spring flexural axis corresponds to and the swivel axis intersects with the rocking axis of the chair for support of the same.

Abstract: A method and means for removing the fire extinguisher dry powder from its pressurized cylinder using a vacuum pump and appropriate apparatus and collecting the powder in a drum and to prevent powder degradation. The apparatus is simple to operate and provides a clean, fast method for discharging and removing dry chemical powder from fire extinguisher cylinders.

Abstract: An eccentric center-distance adjuster for rotary die cutters having load-biased screw adjustment of the center-distance between rotary die cutting cylinders which is stabilized against the die cutter frame in the same direction as the cutting load between said cylinders thereby minimizing cylinder bounce.

Abstract: A lamp included in electric fences, at one or more posts thereof. The lamp indicates when an electric charge is flowing through the electric wire, at full charge, partial charge or no charge.

Abstract: This invention relates to electric projection screens to effect the coordinated shifting of the screen surface into and out of picture-projecting position of the type mounted in or to the ceiling or to the wall of a room and more particularly to a means to quiet the operation of the screen roller tube and its appendages during rotation of the roller tube.

Abstract: A controller for maintaining pick-up tines on harvesting reels at predetermined orientation in space as the reel is rotated for severing crops from the ground having inherent structural self-compensation for wear and dimensional tolerance stack-up in the assembly of parts thereof and induced reduction of peak loads thereon by means of a pendulously-suspended control spider which is pivotally mounted on the machine in the direction against and nominally on the line of action of the applied load on said spider from the gathering and cutting of crops by the pick-up reel of said machine.

Abstract: An apparatus for quick changing of tooling in heavy die sets is disclosed wherein interchangeable die shoes and tooling are piloted and guided on the bed of the press during operation of the same. Oil-hydraulic jacks lift the die shoe from the bed of the press and disengage the pilots and pneumatic cylinders disengage and retract the guides therefrom for roll-on and roll-off of the shoe from the press giving free access to the die shoe and to the underside of the blanking punch holder plate for repair or change of tooling. Guide sleeves for alignment of the blanking punch with the blanking die during operation of the press are pneumatically disengaged from leader pins in the die shoe providing transfer clearance for the roll-on/roll-off.

Abstract: A washable retainer which holds a wig on the head with friction-surfaced, flat, pillow-like pads having thickness to suspend the abrasive wig net from contact with the scalp and give body to the same, which wig will stay put in place and not allow shift when normally worn and which does not irritate the scalp of the wearer, because of its unique capability to conform to the natural contours of the head.

Abstract: A tilt can or container for pouring flammable liquids having means for simultaneously venting the can when opening the pouring spout.

Abstract: An inexpensive bathroom cabinet plastic molded in one piece having integrally formed shelves, with a mirrored door pivotally attached to the cabinet upper and lower walls at one side having upper and lower cooperating pivots.

Abstract: An portable electronic device that generates sound of handclapping. A small, easily-carried and easily-used device that eliminates fatigue from physical clapping and makes the user appear more sophisticated.

Abstract: This invention relates to means to produce an artificial reef or floating breakwater wherein a series of buoyant disks are strung on a buoyant flexible line in spaced relation to each other with the lower end of the line being tethered to its own anchor. These tethered disks are placed preferably in about 6 to 18 feet water depth from the shoreline. A series of these disk-anchors are strung along in or out of lines paralleling the shoreline and in various depths of water to provide effective grid means for eliminating or at least substantially reducing the erosion effect along shorelines resulting from wave action.The placement of the disk-rope anchor units is preferably in the water paralleling the shoreline and each unit is spaced apart from the other. However, the spacing is not critical but to accomplish the results sought to be achieved, the spacing ought to be close enough to be effective and yet not tangle with each other.

Abstract: A self-piercing riveting system comprising a headless rivet made from steel or a suitable material that provides compressive strength superior to that of the materials to be riveted together and of a height or thickness equal to the sum of the materials to be riveted, the said rivet having flat end surfaces and its body being peripherally concaved between its ends, a die having an opening therethrough of the size and shape of the piercing end of the rivet, and a punch for driving the rivet through the materials to be fastened, the said die and punch each being provided with staking lugs for engaging the margins of the pierced opening through the said materials so as to cause the materials to flow radially against the concaved body of the rivet.

Abstract: A new and distinct tropical indoor variety of Aralia distinguished by its light green leathery leaves which have a silver white margin completely around the tri-pinnately lobed leaf outline, by its more self-branching and compact growth habit, and by its more abundant densely growing foliage.

Abstract: A new variety of lily plant of the chalice-type Asiatic Hybrid particularly distinguished by the gold coloring of its five to six inch diameter flowers which are borne in raceme arrangement on tall strong stems and strong upright pedicels, usually with one bud or flower on each pedicel, and by its habit of forming aerial bulbils in the leaf axils at blooming time.
