Abstract: A magazine assembly for a firearm and a related method are disclosed. The assembly has a magazine housing defining a track, and a follower assembly. The magazine housing is configured to constrain a cartridge as the cartridge is moved within the magazine assembly such that majority of a proximal surface area of the cartridge does not contact the magazine housing, and a distal tip of the cartridge does not contact the magazine housing.

Abstract: A fluid jacket for a disc brake is provided that promotes a balanced flow of cooling fluid throughout the fluid jacket to most effectively remove heat from the disc brake. The fluid jacket includes an annular body configured for engagement with a friction surface. The annular body defines a plurality of concentric flow passages. The annular body further defines first and second axial flow passages in fluid communication with first and second flow passages, respectively of the plurality of concentric flow passages, with the first and second flow passage separated by a third concentric flow passage. The annular body further defines a radial flow passage extending between the first and second axial flow passages, and a fluid inlet in fluid communication with the radial flow passage.

Abstract: An industrial brake is provided through which tension and emergency braking are initiated at opposite axial ends of the brake in order to improve packaging and maintenance of the brake and to enable the addition of an emergency brake function to existing tension brakes without substantial modifications to the brake. The brake includes a housing disposed about a driven shaft and friction plates coupled to the housing and the shaft respectively. One friction plate comprises a liquid cooled fluid jacket. One end cap assembly is disposed at one axial end of the housing and provides a tension brake function. Another end cap assembly is disposed at the opposite axial end of the housing and provides an emergency brake function.
