Abstract: A light weight, inexpensive rotary drum mixing device is provided in which an essentially pear shaped drum, open at the small end and having an axially elongated socket at the large end, is rotatably supported on a unitary base having a transversely extended forward end and an upwardly and angularly extending rear end providing a bearing portion detachably engageable with said socket to rotatably support the drum at an inclination of about 35.degree., readily engageable means on the bearing portion and socket for preventing unintended axial movement, the forward end of the frame being slightly forward of the center of gravity of the rotatably supported drum to firmly support the same as drum contents are being mixed by rotation of the drum, and providing a pivot fulcrum for tilting the assemblage to discharge contents of the drum, and groove means adjacent the large end of the drum facilitating application of circumferential force to impart controlled rotation to the drum.

Abstract: An air retaining and bead-seat-lock device for pneumatic tire wheels is provided having air retaining engagement with an aperture in a tire rim adjacent the seated tire bead, and having two positions of operative engagement with the rim, one position disposing the inner end of the device substantially flush with the inner rim surface facilitating air-pressure seating of the tire bead against the rim flange, and the other position disposing an end to protrude beyond the inner rim surface adjacent the tire bead to support the same in seating engagement with the rim flange. In its simplest form the device comprises an elongated threaded shank closely fitting a threaded aperture in the rim and having an enlarged head externally of the rim adapted for clamping an air sealing gasket against the rim, and being movable between the first and second positions by rotating the threaded shank to appropriately position its inner end.

Abstract: A light weight, inexpensive rotary drum mixing device is provided in which an essentially pear shaped drum, open at the small end and having an axially elongated socket protruding from the large end, is rotatably supported on a unitary base having a transversely extended forward end and an upwardly and angularly extending rear end providing a bearing portion detachably engageable with said socket to rotatably support the drum at an inclination of about 35.degree., readily engageable means on the bearing portion and socket for preventing unintended axial movement, the forward end of the frame being slightly forward of the center of gravity of the rotatably supported drum to firmly support the same as drum contents are being mixed by rotation of the drum, and providing a pivot fulcrum for tilting the assemblage to discharge contents of the drum, and means externally of the drum facilitating application of circumferential force to impart controlled rotation to the drum.

Abstract: A downspout baffle mechanism is disclosed, adapted for use in conventional, vertically disposed downspouts for diverting controlled amounts of water descending in such downspouts to water collecting means located above and spaced from the normal downspout terminus. The baffle mechanism is controlled by the rise and fall of a suitable float in the water collecting means through a motion reversing mechanism such that the baffle diverts water through a side opening in the down position of the float and substantially seals such side opening in the up position of the float. The baffle and control mechanism is preferably incorporated in a preformed assemblage adapted for insertion in a conventional downspout by merely removing, at the desired elevation, an appropriate length of the downspout.

Abstract: A water level control for swimming pools is provided in the form of a casing for suspension on a ladder, pool wall, or pool edge having a float-controlled valve detachably coupled with a pressure water supply and adapted to open as the float drops a predetermined distance within the range of about 3/4 inch to 1 inch, said casing having a transverse partition intermediate its upper and lower ends which supports the valve and float assemblage, and said partition and casing bottom being apertured to permit egress of water fed through the valve while in open position while at the same time acting as baffles to maintain an essentially stable water level within the casing in spite of the wave action which may prevail in the surface of the pool water. Positioning of the casing is facilitated by external high and low water level markings which align with the water levels within the casing at the upper and lower limits of float movement.

Abstract: A support device is provided for strengthening the hand gripping of racquet handles and other shaft members in the form of an elongated sheet member formed at least in part of resiliently expansible material having means at one end for adjustably securing the member to a shaft to be gripped and an aperture at the other end of the member of a size to closely and expansibly engage the shaft closely adjacent the gripping hand with the spacing of said securing means and aperture being such that the device as mounted on a racquet handle or other shaft member forms a loop which receives the hand with sufficient resilient tension to hold the shaft firmly to the palm of the hand even as the gripping action of the fingers may be relaxed. The device can be a unitary member or a two-part member with overlapped portions aligning with the back of the hand and adjustably secured together by quickly engageable and disengageable means.

Abstract: New and improved germicidal iodine compositions are provided in which iodine levels, in the presence of organic adjuvants containing at least carbon, hydrogen and oxygen atoms, are maintained for extended periods of time in the presence of iodide, through the addition of iodate and control of pH within the range of pH 5-7.

Abstract: A unitary run-flat insert for inflatable tires is provided in the form of a split ring having sufficient flexibility, through separation at the split portion thereof, to pass over the rim flanges of a tire mounting rim and having an inner periphery closely and circumferentially engaging the rim when the split portion is closed, with lock means at said split portion adapted for automatic engagement as the ends forming said split portion are moved into juxtapositioned alignment. As closed by the lock means, the insert engages the rim in a manner to rotate therewith in normal operation, but to slip circumferentially thereof when riding on a deflated tire.

Abstract: A tennis racquet comprising a frame providing an open, tensioned string receiving, playing head of generally elliptical contour, and an elongated handle extending from one end of the head and terminating in a hand grip, the contour of the open head at the hand grip end thereof being closed at a point between the center of gravity and the hand grip end of said racquet. A preferred form of the racquet comprises a unitary frame bowed in its central portion to form a generally elliptical head contour and continuing as coplanar throat and shaft extensions which are joined at their extremeties in a hand grip, and the first joining of the ends being at a point between the center of gravity and the hand grip end of the racquet. Central longitudinal strings may join the frame at points closer to the hand grip end than is the center of gravity, and the longitudinal strings are under somewhat greater tension than the transverse strings.

Abstract: An improved iodine tincture is provided by incorporating therein a small amount, preferably about 0.25 to 2.5 parts, per part by weight of iodine, of povidone, 1-vinyl-2-pyrrolidone polymer. In these proportions , the povidone modified tincture of iodine exhibits markedly reduced tendency to burn or sensitize skin areas on which it dries, is stable, and at the same time retains the essential germicidal activity of unmodified tincture of iodine. The new products can be formulated directly, or as concentrates yielding the improved tincture upon extension with a prescribed amount of aqueous-ethanolic diluent.
