ABSTRACT The object of the invention is to provide a flexible track system having a number of identical track sections interconnectable to form curves, banks and slopes, as well as straight segments, each of the sections having an arcuate surface portion with a periphery of a given diameter and an arcuate edge of the same diameter, the edge being configured for proximate engagement with the periphery of the arcuate surface of an adjacent section. Depending rib means are provided at the periphery for frictionally engaging slot means in proximate relation to the edge, the slots being elongate for enabling pivotal movement of one section relative to the next. Upwardly diverging sidewalls are configured for overlapping frictional engagement for assisting in maintaining interconnected sections in fixed relation. The arcuate surface portion is deflectable to enable the formation of sloping segments of roadway. Other track sections are provided with mating interconnections on one end thereof for providing interconnection to other types of track sections.

ABSTRACT A new and useful phonograph stylus-shielding apparatus and a stylus-unshielding apparatus are provided in combination with a phonograph and recorded-message carrier. The phonograph includes a housing having a top wall provided with an opening for receiving the recorded-message carrier. A turntable is rotatably mounted in the housing in alignment with the opening and a tonearm is pivoted to the turntable for rotation thereby. A reproducing stylus extends upwardly from the tonearm for engaging the recorded-message carrier when it is in position within the opening. The stylus-shielding apparatus automatically shields the stylus from access through the opening when the recorded-message carrier is removed from the opening and the stylus-unshielding apparatus automatically unshields the stylus when the recorded-message carrier is positioned within the opening.

Abstract of the Disclosure An electronic football game includes an insulating housing supporting a microprocessor control circuit, a plur- ality of user-operable keys, and a display. The user oper- able keys facilitate information input to the microprocessor system. The display includes a perspective view of a portion of a football field as it would be seen by a ball-carrier including a pair of merging sideline markers, an end zone, a goal standard, and several yardage markers. A plurality of illuminatable defensive player characters are arranged in three rows facing a stationary ball-carrier positioned in the center foreground of the display. Consistant with the perspective view, the defensive players in the second and third rows are progressively smaller than those of the first row. Under the control of the microprocessor, apparent movement of the stationary ball-carrier is depicted by moving the entire de- fensive player character illumination pattern in the direction opposite to the intended ball-carrier motion.
