  • Patent number: 10401105
    Abstract: A multi-caliber automatic rifle (AR) magazine is configured to alternately receive a first cartridge having a first caliber and a second cartridge having a first caliber. The multi-caliber AR magazine includes a first pair of ribs, a second pair of ribs, and a third pair of ribs such that the first pair of ribs and the second pair of ribs are configured to both support the body of the cartridge when loaded in the magazine. The second pair of ribs are indented toward a center of the multi-caliber AR magazine housing more than the first pair of ribs such that a distance between the second pair of ribs is less than a second distance between the first pair of ribs. The third pair of ribs can be rebated to form a dual-curved rib having a central convex portion connected between two concave portions.

  • Publication number: 20130285321
    Abstract: A diverter for receiving printed products in a single stream and diverting the printed products into a plurality of streams is provided. The diverter includes a first rotating body rotating about a first axis and including first, second and third circumferential sections positioned around the first axis. Each circumferential section of the first rotating body extends radially a different distance from the first axis. The diverter also includes a second rotating body rotating about a second axis and including first, second and third circumferential sections positioned around the second axis. Each circumferential section of the second rotating body extends radially a different distance from the second axis. The first and second rotating bodies divert the printed products into three separate streams at a diverting area between the first and second axes. The diverter also includes a steeple positioned downstream of the diverting area.

  • Patent number: 5413042
    Abstract: A lock-up assembly (20) for securing a printing plate (22) on a plate cylinder (10) includes a rotatable lock bar (32) and a spring biased linkage mechanism (36). The linkage mechanism (36) has a first over-center condition in which it rotates the lock bar (32) toward a locked position, and has a second over-center condition in which it rotates the lock bar (32) toward an unlocked position. A movable blocking member (82) blocks the linkage mechanism (36) from switching to the second over-center condition under the influence of centrifugal force when the cylinder (10) is rotating during a printing operation. A hand held tool (40) engages the linkage mechanism (36) to switch it between the first and second over-center conditions upon manual manipulation of the tool (40). The tool (40) also engages the blocking member (82) to move the blocking member (82) from the first position to the second position when the tool (40) is moved into engagement with the linkage mechanism ( 36).
