Abstract: A reel blade mower that provides for proper reel blade contact pressure on the bed knife at all times without any system adjustment. The mower includes a free floating reel blade suspended on a pair of pivotal support arms that is not mechanically fixed to a rigid position, but that is free to move vertically relative to the bed knife. The overall force of the reel blade in contact with the bed knife (contact pressure) is determined by combining the downward vector from the weight of the blade system and the force vector generated by the rotary movement of the reel blades. The mower is not damaged by debris engaging the reel blade or bed knife which easily passes through.

Abstract: A circuit for protecting an AC driven load that is controlled by a solid state device, such as a triac, or inverse SCR's, or the like. Whenever the AC power output of the control is asymmetrical to the load, the circuit produces a signal capable of shutting down the AC power to the load, sounding an alarm, switching to a different controller, or signaling another load protecting reaction. The protection circuit continuously measures each individual half cycle of the AC output from the controller to the load and provides for phase shifting about a reference point, resulting in summing (or nulling) of the AC output half waves (positive and negative) at the reference point. The summing (or nulling) reference point is coupled to the gate of a switching element connected across the AC input line, the switching element being responsive to a positive or negative voltage above a predetermined threshold value.

Abstract: A device useful for exercising in a swimming pool or other body of water which allows the person to be supported in a substantially seated upright position in the body of water such that the neck, head and upper shoulders of the person remain out of the water, allowing the person to exercise the legs, arms and torso while neutrally buoyant. The device is constructed of a buoyant body that is contoured to be stable and recessed laterally to be comfortably straddled by a person exercising, and includes a smaller forward portion and a larger (in volume) rear portion upon which the person is seated while in the water. The particular shape of the device is such that the center of buoyancy of the body is positioned to substantially be disposed forward of the vertical spine (near the center of gravity) of the user for balance and stability in the water. The user, may thus sit upon the body and freely move his legs and arms for exercise in a seated, upright position.
