  • Boat anchor including releasable coupling means
    Patent number: 4655158
    Abstract: An improved boat anchor assembly including an anchor shank having a fluke pivotally connected thereto and supported for angular displacement about an axis normally related to the longitudinal axis of the shank, motion limiting stops mounted on the shank for arresting pivotal motion of the flukes relative the shank, the shank being provided with a pivotal coupling interposed between the ends thereof and pins for imparting stability to the shank and adapted to deform under angularly applied loads of predetermined magnitudes whereby the shank-fluke connection is permitted to "break" for facilitating recovery of the anchor.

  • Control in continuous casting to enhance feeding
    Patent number: 4588018
    Abstract: A method is provided for optimally operating a wheel-type continuous caster such that solidification porosity and macrosegregation in the continuous strand thus produced is substantially minimized while casting speed is substantially maximized subject to that condition. Continuous casting is adjusted from an operational condition where solidification porosity is forming by changing the solidification rate so as to cause the terminus of the solidification zone to shift location in the direction of increasing metalostatic pressure until the point where solidification porosity ceases to form or its occurrence is minimized; further provided that in the vicinity of the solidification terminus the direction of increasing metalostatic pressure is maintained counter to the direction of casting.

  • Method of hot-forming metals prone to crack during rolling
    Patent number: 4584029
    Abstract: A method of continuously casting a molten ferrous alloy in a casting means to obtain a solidifed cast bar at a hot-forming temperature, passing the cast bar at a hot-forming temperature from the casting means to a hot forming means, and hot forming the cast bar into a wrought product by a two-stage reduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a substantially uniform fine grained, equiaxed or cell structure in the outer surface layers of the cast bar by a selected small amount of deformation of the cast bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area forms the wrought product.
