Abstract: An injection molded shower stall assembly or bathtub assembly particularly for use in a recreational vehicle includes an injection molded tub or shower base, which includes an integrally formed drainpipe which is externally threaded and adapted to easily and permanently be connected to plumbing for the recreational vehicle. Injection molded walls are formed to surround either the shower stall or tub. The injection molded walls have lower edges that interfit with edges of the tub or shower stall in a way which prevents water from flowing behind the preformed walls and holds the lower edges of the preformed walls in position, eliminating the need for any type of penetrating fastener along the base of the walls. The walls are formed in multiple sections that fit one on top of the other, with interfitting lower and upper edges, again to reduce the need for penetrating fasteners and to hold the sections in position.

Abstract: A shell with a subcaliber penetrator, which has a conical tailpiece, and with a basically disk-shaped propulsion element, wherein the conical tailpiece has a frustum-shaped recess that is open towards the rear end. The propulsion element is joined with the penetrator, preferably by a screw connection (projectile fastening bolt). To this end, a bolt element joins the propulsion element and the penetrator in the area of the tailpiece and has a borehole that is open at the rear end, into which propellant charge gases flow when the shell is fired and cause rending of the bolt element and thus separation of the propulsion element from the penetrator.

Abstract: The invention relates to a method for producing a penetrator (10) from a tungsten heavy metal with a high fraction of tungsten and an outer sheath (7), which consists of a material that is more ductile in relation to the penetrator core (6).
