Abstract: The described embodiments relate to electronic devices. One exemplary device includes a pair of sidewall components extending between respective top portions and bottom portions, the bottom portions lying in a plane that extends between the bottom portions. The device also includes a bottom component joined with and extending between the bottom portions, wherein the bottom component has a non-loaded disposition relative to the plane and a loaded disposition relative to the plane, and wherein at least a portion of the bottom component is closer to the plane in the loaded disposition than in the non-loaded disposition.

Abstract: A sheet separating machine automatically separates and removes a sheet of a dry nonextendable film from a printed circuit panel. The machine comprises a plurality of feeding rollers carrying the panel with the films attached to either or both sides thereof through the machine. The stop lever interrupts a movement of the panel at a predetermined location for a selected time interval. An edge separator for loosening a film edge during the interval rides along the film edge and separates the film edge from the panel by utilizing pressure wheels and turbulent air flow. Knife means breaking a bondage between the panel and the film force the film to completely separate from the underlying panel. The separated film is conveyed by the guide means toward a film accumulator.

Abstract: A stacker-loader is positioned at the end of a conveyor line for receiving printed circuit boards as they follow each other in series or sequence along the conveyor. The stacker-loader converts the series of boards into a stack of boards, one aligned over the other on a cart which may be removed. The boards are so stacked without any one sliding over another, since the conductive strip lines on confronting boards might catch on each other. The stacker-loader comprises a field of driven rollers for the enabling of the boards to sequentially travel in series one after another when they leave the conveyor. A pair of spaced parallel cantilever arms are positioned to receive, between themselves, each of the printed circuit boards as it is delivered from the field of driven rollers. An aligned plurality of wheels are mounted on and extended from confronting surfaces of the cantilever arms for supporting the boards as they move along the arms.

Abstract: Solar energy is collected by a plate-shaped panel of pliable plastic construction. The two major walls of the panel whose edges are sealed to each other consist of transparent and black plastic respectively and bound a cavity. The panel is expanded by air introduced by a blower and discharged through a restricted outlet. A radiation trap of pleated, transparent plastic sheeting is fastened in the cavity to the transparent wall. The hot air discharged from the panel when it collects solar radiation provides all the necessary energy for operating an absorption refrigeration system of the Electrolux type.
