Abstract: A process and apparatus for forming a thin-walled, elongated member having superior strength properties from an age hardenable copper base alloy is described herein. A slug or billet of a slurry cast, age hardenable copper base alloy is formed into a semi-solid slurry having about 10% to about 30% of the alloy in a liquid phase. The semi-solid slurry is then thixoforged to form the thin-walled, elongated member. Thereafter, the member is age hardened to provide a product having desired strength properties. The process and apparatus of the instant invention may be utilized to form cartridge casings.

Abstract: A boiler blowdown monitoring system wherein the conductivity of the water in the boiler blowdown line is monitored to determine if it exceeds either a preset maximum or minimum level. The system includes a blowdown sensor, a blowdown valve, a blowdown controller and an interrogation means. The water conductivity is sensed by the sensor located on the blowdown line and transmitted to the interrogation means (e.g. microprocessor) through the boiler blowdown controller. If the sensor senses a water conductivity level above a preselected maximum conductivity level or below a preselected minimum conductivity level after a predetermined time period has passed since the boiler blowdown valve was opened, then an alarm signal is sent to the boiler operator.

Abstract: Disclosed is a stripping composition for effectively removing an organic polymeric material from a substrate. The stripping composition is essentially free of phenol compounds and halogenated hydrocarbon compounds and contains a select amine compound and an organic polar solvent. It has been found that the stripping composition is highly effective, even when the organic polymeric material to be removed from a substrate is a positive resist which has been subjected to high temperature post-baking operations.

The method results in significant cell voltage reductions in electrolytic cells employing as separators porous diaphragms or ion exchange membranes.

Abstract: An all-plastic cartridge case is disclosed. The case is all-plastic polyethylene and has a hard-plastic rim and a soft-plastic glass-filled high density polyethylene basewad. The basewad is of a plastic similar to but stronger and tougher than that of the shotshell tube while the rim is of a hard plastic which is chemically dissimilar to the tube. The rim is mechanically locked to the tough basewad and the basewad is chemically bonded to the tube. Also disclosed is a two-step method for molding such a shell with a triple plastic head. Either the rim or the basewad is molded first and the other of the two is molded through the first.
