Abstract: The invention is a self-propelled drivewheel steering power mower which can be operated in a standing or sitting position, including a pair of variable flow hydrostatic pumps with tiltable swash plates, each of which drives one of a pair of drivewheels. A vertically mounted steering shaft is rotatably supported on the mower for rotation about an axis concentric with said shaft; and a T-shaped steering handle bar is rotatably journaled to the end of said steering shaft for twisting about an axis concentric with said handle bar.

Abstract: Cattle head gate on a squeeze chute which includes a pair of gates which open outwardly, with each gate pivotally attached to the chute about separate vertical axes, the vertical axis of each gate being positioned longitudinally outside of the squeeze chute. Actuating arms connected to the gates swing the gates into a closed position with a longitudinal component of the gates' movement in the same direction as that of the animal.

Abstract: The present invention is a decoy hunting blind and cart which both provides a goose blind structure and functions as a cart. The hunting blind and cart positions an enlarged decoy directly over a hunter reclining on a flexible hammock provided on the cart which holds the hunter slightly off the ground. Offset to one side of the cart is a support framework for the enlarged decoy, which is easily rotated out of the way permitting the hunter to shoot. The hunting cart is a wheel-barrow like structure which permits the hunter to transport all of his decoys which are set up in the field to various locations.

Abstract: The oven of the present invention is a low profile, dual conveyer oven including an oven cabinet, two closely spaced conveyers and an air heating and circulation system. The conveyers and the oven cabinet are adapted so that the conveyers can be easily removed from the from the front or side of the oven cabinet. The oven cabinet houses the conveyers, ducts and manifolds which all can be easily removed for cleaning or other maintenance. Each of the conveyers include separately controlled drive motors capable of driving the each of conveyers at different speeds and in different directions. The air heating and circulation system features a transverse mounted burner tube, side mounted return air ducts, a central return air opening, common shaft mounted side fed dual centrifugal fans and hot air manifolds.

Abstract: An overhead bicycle storage rack for hanging a bicycle vertically between the ceiling joists of a building with sufficient headroom to walk thereunder, including a pair of U-shaped brackets, each bracket having a width approximate the spacing between ceiling joists and a depth approximate the radius of the bicycle wheel. Each bracket is positioned laterally between an adjacent pair of ceiling joists with the ends of the brackets attachable to the ceiling joists with the remainder of the bracket extending above the ceiling joists and a hanger element supported on each bracket for supporting an individual wheel of said bicycle.

Abstract: An adjustable aircraft control stick comprising a vertically-positioned column pivoted about the pitch axis for controlling the elevators and a yoke member pivotally mounted to the upper end of the control column about an axis parallel to the roll axis of the aircraft for control of the ailerons. The yoke member including a series of socket openings positioned longitudinally on the yoke and a hand grip member releasably engageable with any of said sockets to adjust for different arm length pilots.

Abstract: A two piece connecting rod assembly for a axial cylinder, internal combustion engine with each rod half having a bearing sleeve at each end for pivotal engagement with the universal joint turnion. The two rods are connected to each other at their centers and spaced apart concentric relations through a pair of raised bosses with mating surfaces and a bolt for retention of the two rod halves as a unified structure.

Abstract: A fuel injection type aircraft fuel system for piston aircraft engines including a gravity flow fuel tank in the aircraft; a pressurized fuel metering unit on the aircraft engine; a fuel line connecting the metering unit to the fuel tank; an engine driven pump in said fuel line positioned in the engine compartment; a vapor separator in said fuel line between the engine driven pump and the fuel metering unit; a first vapor vent line connecting the vapor separator to the fuel tank; a fuel reservoir in said fuel line between the fuel tank and the engine driven pump; a submerged auxiliary pump in said reservoir to charge said system; an auxiliary pump bypass valve connected and parallel to said auxiliary pump; and a second vapor vent line connecting the reservoir to the fuel tank.

Abstract: A two-wheeled hand truck comprising a pair of side frames molded from highstrength plastic formed in an open truss with compression and tensile members. The side frames are held in a rigid parallel relationship to each other by cross rails, handles and a toe plate with integral stiffeners attached to the side frames.

Abstract: A sea current generator aquarium including an air fight water chamber located at one end of the aquarium with a first opening into the aquarium extending across the bottom of the chamber. At the opposite end of the aquarium between the end wall and a horizontal divider wall is a second opening into an upper chamber which is open to atmosphere. A constant flow air pump is connected to the water chamber for pumping air in and expelling water out of the first opening into the aquarium and then into the upper chamber. An air valve which cycles open or closed, connects the water chamber to atmosphere and in its vented position, the valve dumps the capacity of the pump and allows the elevated water column in the aquarium and upper chamber to move back into the water chamber through both openings until the valve cycles closed thereby creating a back and forth current of water within the bottom regions of the aquarium.

Abstract: A horizontal directional boring machine pivotally mounted to a tractor about a vertical axis of rotation positioned over a common entry point into the ground which permits multiple direction bores which radiate from said common entry point all with a single set-up of the boring machine.

Abstract: A humidifier water bottle having an opening therein with a funnel shape to assist filling, the same opening also performs a valving function as to the water in the bottle which blocks the flow of water as the bottle is rotated from a horizontal position to a near vertical position whereupon the geometry of the opening allows the water to flow into the reservoir of the humidifier and maintain a constant level.

Abstract: A portable PVC resin blending system mounted in a semi-monocoque steel silo having multiple levels therein. The various components of the blending system are mounted within and attached to the silo and lifting lugs on the silo capable of lifting and tilting the silo from a vertical to a horizontal position for transportation and re-erection.
