Abstract: The present invention includes a screw tip for an extruder screw for effecting mixing in an extruder. The screw tip has a shaft portion and at least one mixing element ring connected to the shaft portion, or a mixing element having an aperture therethrough, or both. The mixing element may have two legs connected by a top portion with the aperture between the two legs to allow flow of extrudate therethrough.

Abstract: A ventilator for straddling an aperture in a roof of a building, the ventilator comprising at least one rectangular cover panel having an interior surface and an exterior surface. A plurality of longitudinally spaced interior walls are provided for supporting the panel over the aperture, with each wall having a portion extending beyond the edge of the panel. A longitudinally extending baffle wall is spaced outwardly from the panel edge and is supported in an upward direction by the lateral portions of the interior walls. A plurality of openings are provided in the baffle wall for draining water from the ventilator, and an upstanding baffle is spaced inwardly of and in line with each opening to deflect any wind-driven rain or snow entering through the opening from entering into the roof aperture.

Abstract: In a sailing game, a number of movable land masses each having a habor therein for placement upon a game board. At least two types of sailing vessels, each having different navigational abilities when moving over the game board. Wind speed and direction indicators for determining the possible movements of the vessels during each turn, wherein all vessels on the game board, and not within a harbor, must be subject to the indicators. Facility and buoy cards acquired by each player allow the player to alter the effects of the wind speed and direction indicators upon his vessel. The winner being the first individual to navigate his vessel from the home harbor to all of the other harbors and return back to the home harbor.
