Abstract: A bird feeder adapted to be suspended from the branch of a tree. The bird feeder includes a tube assembly (including a lower tube and an upper tube telescopically engaged therein) and a base plate extending radially outwardly therefrom and on which a feed holding can is mounted. A cone is fixedly attached to the upper tube and positioned in vertically spaced relation above the base plate, thereby serving as a hood to the base plate and feed holding can. The cone and upper tube are supported in position by a series of elongated, resilient tines which are fixedly secured at one end to the can and with their opposite ends being in contacting, supporting relation to the inwardly facing surface of the cone. The tines permit the cone together with the upper tube, to be forced downwardly along the longitudinal axis of the tube assembly in the event of a squirrel climbing on it trying to gain access to the feed, thereby denying the squirrel access to the feed.

Abstract: A game for both entertainment and education intended to increase familiarity and facility with binary mathematics and typical logic functions of the type normally carried out by digital computers. Two or more players each select by random chance a succession of binary digits. Instructions for operations to be performed on the digit sequence are likewise selected at random by the players, such operations being of the types typically performed in the arithmetic logic unit of a digital computer. In one embodiment of the invention, each digit in the sequence is temporarily recorded by each player on game board apparatus and is changed in accordance with the operations performed as the game progresses. A wide variety of game rules may be devised for carrying out adversary type games and determining a winner.
