Abstract: An apparatus for carrying construction panels in front and side carry configurations. The apparatus comprising a dolly frame, wheels, a dolly raise assembly so as to permit movement of a car and a load carriage along the dolly frame, a pivot mount hingedly mounted to the car and a load support, wherein the load support is pivotable relative to the pivot mount about a pivot axis between a front carry position and a side carry position. In another embodiment, an apparatus comprising a dolly raise assembly for controlled movement of a load carriage along the longitudinal extent of a dolly frame, and a panel lift fixable to the load carriage for lifting and orienting construction panels for attachment to a wall or ceiling. The panel lift having a lift frame with a panel carriage track, a panel carriage for supporting the panel, and a panel carriage raise assembly for controlled movement of the panel carriage along the panel carriage track.

Abstract: A flexible fabric sling for use by two attendants in lifting and transporting a person with limited mobility, the sling including a thigh band releasably securable about the person's thighs, a torso band releasably securable about the person's torso, a dorsal strap extending between the thigh band and the torso band, and handles graspable by the attendants. The length of the dorsal strap is adjustable to accommodate persons of different heights.

Abstract: A portable, self-contained tennis ball throwing apparatus is disclosed which includes a constantly rotating cam having gradually increasing radii of successive points around its periphery and an abrupt transition from a maximum radius to a minimum radius, a pivotally mounted throwing arm having one end biased into contact with the periphery of the cam and supporting a ball receiving cup at its other end, and a resilient member for biasing the throwing arm, such that the cam effectively cocks the throwing arm at a relatively slow rate and releases the throwing arm to move under the influence of the resilient member to impart a throwing force to a tennis ball. The housing of the apparatus is mounted on a carriage which is movable with respect to the housing to change the pitch angle thereof, and, therefore, the angle of trajectory of a thrown ball. The ball receiving cup is also adjustable to change the angle of trajectory of the thrown ball.
