  • Method and system for creating and maintaining a frozen surface
    Patent number: 6253558
    Abstract: A method of constructing a heat exchange system for a medium to be frozen, including the steps of: extruding a composition to form a reconfigurable tube; cooling the tube with the tube in a substantially straight configuration so that the tube is substantially set in the straight configuration; after cooling, reconfiguring the tube from the straight configuration; transporting the tube reconfigured from the straight configuration to a site at which the tube is to be used; and at the site placing the tube in the straight configuration and connecting the tube in a medium to be frozen so that a fluid within the tube is in heat exchange relationship with the medium to be frozen.
    Type: Grant

    Inventors: Robert Stillwell, Michael Rzechula
  • Method and system for creating and maintaining a frozen surface
    Patent number: 5970734
    Abstract: A method of manufacturing a tube includes the steps of preparing a composition using ethylene vinyl acetate, extruding the composition to form a tube, and cooling the tube with the tube in a substantially straight configuration so that the tube is substantially set in a substantially straight configuration. Moreover, a system for creating a frozen surface on a medium includes a mechanism for exchanging thermal energy between a medium and a coolant, a mechanism for removing thermal energy from a coolant, and a mechanism for transporting a coolant between the mechanism for exchanging thermal energy between a medium and a coolant and the mechanism for removing thermal energy from a coolant.

  • Ice resurfacing spreader
    Patent number: 5133139
    Abstract: An ice resurfacing spreader attachable to an ice resurfacing machine comprises an elongate spine, a plurality of elongate fibers having a free and a treating end bound by the spine away from the treating end, the fibers spaced in a fore aft and lateral direction with respect to the spine, the spine being attachable to the frame of an ice resurfacing machine so that the treating ends of the fibers lightly contact the ice surface in an ice resurfacing operation, the treating ends of the fibers being spaced sufficiently from one another to allow the passage of a resurfacing fluid therebetween and thereunder as the ice resurfacing spreader is drawn along a subjacent surface being resurfaced.
