Abstract: The L-shaped, end cap is adapted to be mounted on a concrete balcony. The balcony has a rise (a vertical height) an upper run and a lower run. The end cap is an L-shaped end piece having a front plate and a lower plate. The front plate of the end piece has a plate rise substantially equivalent to the concrete balcony rise. The L-shaped end piece has a depending lip along the interface between the plate rise and the lower plate run. The depending lip is adapted to collect and disperse water droplets therefrom. Preferably, the end piece is made of pultruded fiberglass. However, the end piece may be made of plastic, stainless steel, copper, aluminum or other similar materials. For example, pultruded fiberglass may be utilized as the end piece. A method of capping a concrete balcony includes covering the rise and a portion of the lower balcony run by adhering plastic thereon and forming, with the plastic, a depending drip edge.

Abstract: A process of imposing an electrical charge on an electrically insulating surface of a moving web wherein a brush electrode contacts the surface. The brush is made up of extremely soft and flexible fiber filaments comprising carbon mounted on a metallic brace which also serves as an electrical contact to supply the brush with d.c. potential whereby the electrically insulating surface is charged to nearly the potential applied to the brush.In order to improve charge uniformity the brush is oscillated in a direction transverse to the direction of web movement.
