  • Composite cutting edge
    Patent number: 5347887
    Abstract: A process for shaping a blade edge and coating the: blade edge to improve the properties thereof is provided. The process includes an ion etching step using a collimated beam to reduce microcracks and an ion assisted processing step wherein ions are used to enhance the properties of a coating. The blade can then be sharpened again. The blade can be made from materials such as metal, ceramic of glass-ceramic.
    Type: Grant

  • Lead chopper
    Patent number: 4249312
    Abstract: A cutting tool for cutting soft ductile materials such as came (a lead or lead alloy extrusion used for leaded glass) without distortion. A thin steel blade is rapidly accelerated by impulse to cut the same. The blade is accelerated either by an electrical solenoid, a hammer, or other suitable means.
    Type: Grant

  • Bearing retainer
    Patent number: 4073552
    Abstract: A ball-bearing retainer in which rigid members support a soft, flexible, highly porous annular body having ball pockets for receiving bearing balls. The annular body is made of a porous foamlike material capable of absorbing between 40 and 80% by volume of a liquid lubricant such as oil, and being capable of supplying 60 to 80% of the stored lubricant to the bearing. Because of its flexibility, the annular body may be of one-piece construction with spherical ball pockets, and may be closely fitted to the bearing races and balls.
