Abstract: A method and apparatus for securing a cut tree is presented. A tree stand has a frustro conical side wall connected to a base at a bottom thereof, and having an aperture at the top. The aperture communicates with the receptacle adapted for receiving a tree trunk. An opening in the frustro conical side wall allows the introduction of water into a cavity defined by such side wall. A further opening in the receptacle communicates with the cavity, allowing water to enter therein and surround a tree trunk received thereby. Securement of the tree trunk within the receptacle is achieved by the introduction of a closed cell foam introduced about the tree trunk within the receptacle, forming a frustro conical ring thereabout.

Abstract: Saving fuel in the operation of a motor vehicle by providing an increased resistance to depression of a gas pedal at increased velocities in a predetermined speed range from a lower velocity up to a predetermined upper velocity. A piston is urged against the pedal by a spring in a cylinder. Adjustments in vacuum in the cylinder are utilized to adjust the spring force constituting the resistance to pedal depression of the piston.
