Abstract: Apparatus for launching a football on a predetermined trajectory comprises a receptacle for holding a football in an axial alignment such that each end of the football is substantially aligned on an initial arc of a predetermined trajectory. The receptacle is coupled to a piston of a pneumatic cylinder for rapidly accelerating the receptacle along the predetermined trajectory for a preselected relatively small distance from a loading point to a release point. A threaded shaft is positioned between the piston and receptacle and driven through a nut for effecting a relatively rapid spin of the receptacle about an axis coincidental with the initial arc of the trajectory during acceleration over the relatively small distance. The football is released from the receptacle at the release point by suddenly stopping movement of the receptacle.

Abstract: The present invention comprises an apparatus for cooling liquid held in a vessel having an externally extending handle. The apparatus comprises a double-walled container having an inner wall and an outer wall radially spaced apart. The inner wall and outer wall are sealingly attached to a generally flat base member. Each of the inner and outer walls extend generally arcuately about the base member and defines a slot extending substantially perpendicular from the base member. The ends of the inner wall are sealingly connected to the ends of the outer wall adjacent the slot and edges of the inner and outer walls distal from the base member are sealingly attached one to the other for defining a closed space between the inner and outer walls. A refrigerant coolant is disposed in the closed space for maintaining the container at a predeterminately cool temperature for a determinable time interval. The vessel is removably positionable in the container with the handle extending through the slot.
