Abstract: A gate operator in a first configuration opens and closes a gate that swings about an upstanding pivotal axis. In a second configuration the gate operator opens and closes a gate that extends and retracts along a straight line. A motor-driven wheel extends from the bottom of an open-bottomed enclosure and is perpendicular to the gate in the first configuration and parallel to the gate in the second configuration. The wheel is driven by a reversible DC motor. Turning a jack screw in a first direction increases the bias on an adjustable compression spring so that the weight of the gate is transferred to the wheel and rotation of the jack screw in an opposite direction shifts weight from the wheel to the gate.

Abstract: A foldable hair brush includes a hollow elongated handle having an elongated opening therein for receiving a brush portion hingedly connected at one of its ends to the handle. A flange depends from the brush portion at one end thereof and extends between a bi-furcated end portion of the handle at which the brush portion is hingedly connected to the handle portion. A pin socket is connected to the distal end portion of the flange and hingedly receives a hinge pin connected across the bi-furcated end portion of the handle so that bristles extending from the brush portion can be moved from an open position through the elongated opening into the hollow interior of the handle for storage purposes. When the brush portion is disposed in a common plane with the handle portion for using the hair brush, the bi-furcated end portion provides great lateral stability for the unit.
