Abstract: A double deadbolt lock having a housing in which two latch bolts are mounted for reciprocal movement between an extended locking position and a retracted unlocked position. The bolts are in transverse alignment so as to have an elongated face on one opposite an elongated face on another. Each of the two opposite faces has a pattern of alternate, allochirally arranged lands and grooves extending obliquely away from one end of the bolts toward the other end. The housing has a keyhole extending therethrough in alignment with the said opposite faces of the bolts. The key for locking and unlocking the bolts has a shaft having a cross-sectional size and shape corresponding to the size and shape of the hole. Opposite edges of the shaft have alternate lands and grooves complementary respectively to corresponding lands and grooves of the latch bolts.

Abstract: A restraint, particularly suited for use in exercising swimmers, characterized by a base adapted to be affixed to a wall of a water-filled pool, a socket of a truncated helmet-like configuration adapted to receive a swimmer's head, coupling means including a universal joint connecting the socket to the base supporting the socket for universal oscillation, and a pair of handles suspended to be grasped by the swimmer. Where so desired, pressure sensing means are interposed between the base and the socket for measuring pressures at which the swimmer's head is applied to the socket and, where further desired, guides of substantially elongated configurations are suspended from the base in substantially spaced parallelism beneath the surface plane of the water and employed in controlling stroking motion of the swimmer.

Abstract: A harvesting device having a harvesting member elongated along a longitudinal axis; mounts affixing the member for rotation about an axis of rotation eccentric to the longitudinal axis of the member; and a mechanism for rotating the member about the axis of rotation to impart a crop dislodging motion.

Abstract: An apparatus for removing mold and other detritus from raisins and the like having an aqueous bath in which the raisins are immersed; an endless conveyor having an inclined, transversely grooved, planar upper run onto which the raisins are deposited from the bath; and a drive mechanism for moving the upper run upwardly in time spaced increments of stepped progression while simultaneously oscillating the conveyor longitudinally so that the mold and other detritus are abraded and shaken from the raisins and conveyed upwardly with the run while the separated raisins gravitate downwardly along the run.

Abstract: A device for securing a work object on a concrete structure in cooperation with a form used in pouring the structure, the device having an anchor member with a head portion; and a fastening member having portions for individually interconnecting the head portion of the anchor member and the form in a first attitude prior to pouring and the head portion and the work object in a second attitude subsequent to pouring.

Abstract: An apparatus for forming a port in a liner installed in a conduit having a lateral opening inwardly overlaid by the liner so that the port coincides with the lateral opening, including a carriage adjustably positionable longitudinally within the liner adjacent to the lateral opening in the conduit; a brake for locking the carriage in fixed position in the conduit; a power driven port forming tool borne by the carriage in substantial radial relation to the liner for adjustable movement outwardly to liner engagement and inwardly to retraction therefrom, for adjustable movement longitudinally of the carriage, and for adjustable rotational movement about an axis longitudinally of the carriage; control means for controlling the position of the tool on the carriage from a position remote from the carriage; and a television system having a camera mounted on the carriage having a view of the tool and a viewing screen at said remote position.

Abstract: A multi-purpose water driven tool, including a water driven turbine mounted on a shaft for rotation in a housing, the housing having an inlet connected to supply water under pressure to rotatably drive the turbine, a housing outlet to discharge the water from the housing after it has acted on the turbine, said shaft extending outwardly of the housing, and a working tool on the outer end of the shaft to be rotatably driven thereby.

Abstract: A method and apparatus for assembling a reel having a pair of axially spaced circular flanges provided with facing annular grooves, a plurality of axially extending staves fitted into the grooves to form a cylindrical drum extending coaxially between the flanges, and a plurality of tie rods extending axially through the flanges within the drum to draw the flanges together, the apparatus having an inner ring assembly removably supported on the rods concentrically within the drum; an outer ring assembly releasably supported on and downwardly of the inner ring assembly concentrically therewith and adapted to open circumferentially so as to be removed from the drum; and a plurality of lances releasably engaging the tie rods for threading the rods through one of the flanges.

Abstract: A flail shredder having a drive shaft mounted for rotation about an upwardly extended longitudinal axis for earth traversing movement transversely of the axis and for adjustable movement transversely of the line of movement; a power drive connected to the shaft; a flail assembly mounted on the lower end of the shaft; a stop limiting the adjustable movement in one direction; a resilient member urging the shaft toward the stop; and a guide wheel mounted concentrically with the shaft for independent rotation, the wheel being disposed for rolling engagement of obstructions so as to urge the shaft away from the stop.

Abstract: A new variety of nectarine tree discovered as a seedling of an open pollenated Red Grand nectarine tree growing in Fresno County, located in the San Joaquin Valley of California. The fruit of the new variety tends to ripen later than the Red Grand variety and is characterized by a strong red color over a moderate orange, the strong red coloring spreads from a substantially solid covering near the base of the fruit to blotches of strong red coloring near the apex.

Abstract: A nectarine tree, generally similar to the Armking Nectarine Tree (U.S. Plant Pat. No. 2,943) which it most nearly resembles, bearing yellow fleshed, semi-freestone fruit of large size for its ripening season which is from five to seven days earlier than the Armking.
