Abstract: This disclosure depicts a novel apparatus for packaging components in a multiple type packaging arrangement which permits the multiply packaged components to either be opened as an entire unit or individually. In particular, this packaging arrangement comprises a plurality of aligned, open ended boxes having disposed over the open ends a U-shaped sheet, the sheet having a middle flat plane and two planes depending therefrom at right angles thereto, the middle plane sealing the open ends of the boxes. The U-shaped sheet dimensioned such that it will overlap the plurality of aligned open ended boxes and the U-shaped sheet having score marks therein corresponding with the ends of the individual boxes permitting individual boxes or groups thereof to be broken away from the plurality.

Abstract: An electrical terminal includes first and second members having elongated complementary arcuate surfaces thereon movable toward and away from each other by a clamping member. The second member is pivotally supported at one end on the first member and is configured so that different diameter conductors can be securely clamped between the arcuate surfaces.

Abstract: An archimedic or logarithmic scroll is used with an axial fan to provide a smooth and relatively quiet air flow over the electric heating elements. Additionally a lip 21 is mounted at the air outlet to prevent heated air from being drawn back through the axial fan.
