Abstract: Disclosed herein is an environmental charging system for providing energy electrically fused bombs without the need for external charging equipment. The system comprises an electrically fused bomb having conventional existing charging well which charging well is usually centrally located along the longitudinal portion of the bomb. An energizing means, which is adapted to be actuated by slip stream air, is fixed within a charging device which is located within the charging well. The energizing means is designed to pop up out of the charging device as the bomb is released from the aircraft such that in its pop-up position it receives slip-stream air which in turn actuates the device. Means are provided for making electrical contact between the energizing means and the bomb only when the energizing means is in its pop-up position.

Abstract: A method of polishing material for lapidary and like purposes, the material and abrasive being tumbled in a vibrated container which alternately compacts the material against a wall of the container and then separates it in order to reduce the time required for polishing. Apparatus for carrying out the method vibrates the container of the material and abrasive so that a portion of its orbit is about a theoretical center which is above and to one side of the center of gravity of its mass.
