Abstract: A portable tank for handling recreational vehicle liquid waste comprising a molded receptacle of synthetic plastic material having wheels, including a caster wheel. The receptacle is provided with an inlet port for receiving liquid waste, and an outlet port defined in a side of the receptacle is opened and closed by a gate valve permitting the receptacle to be easily emptied.

Abstract: A portable tank particularly suitable for handling recreational vehicle liquid waste of relatively large capacity, i.e. 30 gallons, including a receptacle formed of a synthetic plastic material having wheels mounted upon one end of the receptacle and a handle support is molded into the lower region of the receptacle telescopingly receiving an extendable and retractable handle. The outer end of the handle telescopingly receives a handle extension having a grip mounted thereon for manually handling the tank, or attachment to a vehicle trailer hitch.

Abstract: A supporting and bracing element is disclosed for engaging an edge of a plate-like unit such as a sealed glazing unit, received by a frame. The supporting and bracing element comprises an elongated disc-shaped body having at least two longitudinally extending edge ribs. At least one loop formation extends between the edge ribs at one of their short sides and also extends perpendicular to the upper- or underside of the edge ribs beyond the thickness of the edge ribs. The loop formation is movable for being jammed between the edge portion of the sealed glazing unit and the surrounding frame bar during the mounting of the sealed glazing unit.
