Abstract

An embodiment of the bomb casing (1) defines a generally conical nose portion (2) and a cylindrical body portion (3). At least one, and more preferably both, of the generally conical nose portion (2) and/or the cylindrical body portion (3) are formed from an additive manufacturing process, which is preferably cold-gas dynamic spraying of metal particles onto a support member. In one embodiment, the generally conical nose portion and cylindrical body portion are integrally formed.

Abstract

The bomb casings 1 define a generally conical nose portion 2 and a cylindrical body portion 3. An embodiment of the process for additively manufacturing the bomb casings 1 includes using additive manufacturing equipment to additively manufacture at least one of the generally conical nose portion and/or the cylindrical body portion of the bomb casing. In one embodiment of the process, the additive manufacturing equipment is configured for cold-gas dynamic spraying of metal particles entrained within a gas stream emanating from at least one nozzle.

Abstract

A concrete batch plant is disclosed including a frame and a transit mixer drum having an open end and a closed end. The drum is configured to be utilized both with the concrete batch plant and on a transit mixer truck. The drum may be pivotally coupled to the frame of the concrete batch plant for movement between a first position in which the open end is positioned to receive cement from a cement supply and to receive aggregate from an aggregate supply and a second position in which the open end is positioned to discharge the mixed cement and aggregate. Further, the drum may be a polymeric drum including an interior surface formed by a plurality of complementary molded helical polymeric sections joined along a helical seam.
