Abstract: A flipper system for retrofitting existing flippers of a pinball game which rotate in operative engagement with a solenoid, with new flippers. The new flippers have an opening which is removably engageable upon an engagement end of a rotatable actuator shaft and can include hollow cavities within a metal body of the new flipper. An improved connection to the existing solenoid is provided by inclusion of a actuator shaft and clamp with the system.

Abstract: A teaching device includes a changeable two channel prerecorded program source, and a console unit including a work booklet. The first channel of the program source includes an audio program comprising a series of spoken words which are audibly reproduced by the console unit and the second channel includes a series of control signals which are operative for actuating lights adjacent prespecified words in the work booklet. The operation of the console unit is coordinated with the audio program so that lights are actuated adjacent to the words in the work booklet as the same words are audibly reproduced by the console unit. One embodiment of the device further includes a plurality of depressible user response buttons on the console unit for indicating responses to questions presented in the audio program.
