Abstract: A paint bucket handle accessory includes a generally elongate grip or handle member for grasping in the hand by a user, with the gripper handle member including a groove extending generally the length of the member along the top side thereof. The groove is dimensioned to receive the wire loop handle of a conventional paint bucket. The accessory also includes a hook member extending outwardly and generally perpendicularly from an opposite side of the gripper handle member to terminate in a hook element. The hook element is dimensioned for hooking under the inwardly and downwardly projecting lip formed in the upper edge of a conventional paint bucket. When a wire loop handle of a conventional paint bucket is fitted into the groove of the grip member, and the hook element is placed under the lip of a paint bucket, the grip member may be grasped by hand to lift and hold the paint bucket, while maintaining the wire loop handle to one side of the opening of the bucket.

Abstract: An accelerometer mechanically attached to a machine senses the machine rotor's unbalance and outputs an electrical signal which is indicative of the magnitude and position of the rotor unbalance. A tachometer generator's rotor is mechanically coupled to the machine rotor and outputs an electrical signal delineating the speed and rotational position (with respect to time) of the rotor. By physically indexing one of the tachometer generator rotor poles (north or south) to an index/mark on the engine rotor, the position of the mark at any instant in time is determined. The physical location of the unbalance is obtained by determining the phase relationship of the unbalance signal to that of the tachometer generator signal. This is accomplished by obtaining simultaneous "snapshots" of the two signals employing multiplexing techniques to alternately sample each signal. The signal is then recorded and later reduced by ground equipment.

Abstract: A circuit is provided for shutting off the motor of an intermittently activated, electrically powered fluid recirculation pump to prevent the pump motor from burning out its windings or bearings. A power control relay is energized to activate the pump motor for a predetermined period of time, allowing the pump to reach steady state flow condition, after which a time delay relay opens and current flows to the power control relay through a pressure switch. The pressure switch opens to shut-off the recirculation pump motor whenever the pump discharge pressure falls below a predetermined minimum.
