Abstract: A method and apparatus of converting or cutting over from an old or existing telephone company main distribution frame to a new digital/electronic main distribution frame. A specially designed tool apparatus, which enables practice of the method, results in a cutover system wherein multiple splicing operation into a main feeder cable are avoided, such multiple splicing operations having proven to be costly and service affecting in the telephony industry. With the relatively inexpensive tool of the invention, the cutover process is greatly simplified and accomplished more efficiently.The present invention further includes an apertured cover apparatus and a pair lifter tool adapted for use in the above system.

Abstract: A toy block is provided having an integrally formed, recessed surface disposed in a portion thereof which defines an open inclined passageway between sides of the block element. Game apparatus may be formed from a plurality of such block elements. The individual block elements may be arranged in various adjacent and spaced apart vertical and horizontal orientations by the players in turn during the initial course of play. After a predetermined number of such block elements have been so arranged, the players may again in turn reorient block elements in attempts to define the longest possible extended path formed by the surfaces and passageways of such block elements and the vertical spaces therebetween.
