Abstract: A panel assembly for use inside the rotatable drum of a clothes dryer for drying plastic containing clothes. The panel assembly comprises: (a) a perforated panel having a plurality of bores, this panel being of a size adapted to conform to the shape of a peripheral sector portion of the drum; (b) polytetrafluoroethylene coating the perforated panel for preventing the lint, dust, and plastic parts of the clothes from accidentally sticking to the panel and from clogging the panel bores; (c) a piano hinge, for edgewisely mounting the panel to the interior wall of the drum sector portion for relative movement of the panel between a closed position, in which the panel generally conforms to the drum sector portion spacedly therefrom, and an open position, in which the panel extends transversely to the drum sector portion interiorly thereof. The panel is releasably locked at its closed position by screws extending through the drum wall and through a panel flange located opposite the piano hinge.

Abstract: A strain gauge balance consisting of an outer longitudinal shell and a monopiece inner center core; the outer shell having a open end and a closed end with a frustoconical bore extending towards the closed end, and the inner core having frusto conical shaped ends, one end being sized to fit within the frusto conical core and the other end being sized to fit into a sting; four radially extending, equally spaced, webs formed within the core and at each end of the core inboard of the frusto conical ends, and a central region of two longitudinally separated, semicircular cross-section parts each being formed within the part, with tensioning rings, one disposed diagonally to the other, and a number of strain gauges secured to the webs and the rings to determine induced strain in 6 degrees of freedom.
