  • Publication number: 20220062733
    Abstract: Batting cages are disclosed relating to practice for games such as baseball and softball. The batting cages described may include a net enclosure, a pitching compartment, a hitting compartment, a first pitching screen separating the pitching compartment from the hitting compartment, a second pitching screen that may cover a portion of an opening in the first pitching screen; a second opening in the first pitching screen; and a guide that directs balls from the hitting compartment through the second opening toward a location in the pitching compartment. Uses of batting cages are also taught.

  • Patent number: 6913824
    Abstract: A method for making agglomerate particles from a composition comprising at least a radiation curable binder and solid particulates. The method comprises the steps of forcing the composition through a perforated substrate to form agglomerate precursor particles which then separate from the perforated substrate. Then, the particles are irradiated to form soldified, handleable agglomerate particles before being collected.

  • Patent number: 6620214
    Abstract: Methods for making ceramic aggregate particles comprising forming a plurality of ceramic aggregate precursor particles from a composition by forcing the composition through at least one orifice in a substrate, at least partially curing the ceramic aggregate precursor particles, and heating the ceramic aggregate precursor particles to provide ceramic aggregate particles wherein solid particulates are bonded together by ceramic binder.
