Claim 10

A display device comprising: a base plate having a display panel on one side, said base plate having at least one opening therethrough and a pair of interengaged movable members mounted thereon; at least one movable element disposed on the display panel, said element being coupled to at least one of said members through at least one of said openings for relative movement therewith; wire means having one end fixed to one of said members adapted to contract upon the application of an electrical current thereto; pulsed electronic means engaging said wire means adapted to selectively apply pulsed electrical current to said wire means thereby contracting said wire means pulling said one of said members thereby moving both said one of said members and the other of said members interengaged therewith moving said movable element connected thereof; a second movable element also disposed on said panel, said second movable element being coupled to at least one of said members for relative movement therewith, each of said elements being normally interlocking to form a single discrete element which separates into said movable elements when actuated by application of said electrical current; and indicia on each of said elements and on said panel normally covered by said interlocking elements and exposed when said elements are moved.

Claim 11

A display device comprising: a base plate having a display panel on one side, said base plate having at least one opening therethrough and a pair of interengaged movable members mounted thereon; at least one movable element disposed on the display panel, said element being coupled to at least one of said members through at least one of said openings for relative movement therewith; wire means having one end fixed to one of said members adapted to contract upon the application of an electrical current thereto; pulsed electronic means engaging said wire means adapted to selectively apply pulsed electrical current to said wire means thereby contracting said wire means pulling said one of said members thereby moving both said one of said members and the other of said members interengaged therewith moving said movable element connected thereto; and each of said movable members including a gear portion meshing with the gear portion of the other of said members, and an elongated arm integral with said gear portion, at least one of said arms being interconnected to said movable element.

Claim 12

A display device comprising: a base plate having a display panel on one side, said base plate having at least one opening therethrough and a pair of interengaged movable members mounted thereon; at least one movable element disposed on the display panel, said element being coupled to at least one of said members through at least one of said openings for relative movement therewith; wire means having one end fixed to one of said members adapted to contract upon the application of an electrical current thereto; pulsed electronic means engaging said wire means adapted to selectively apply pulsed electrical current to said wire means thereby contracting said wire means pulling said one of said members thereby moving both said one of said members and the other of said members interengaged therewith moving said movable element connected thereto; and each of said movable members including a gear portion meshing with the gear portion of the other of said members, and an elongated arm integral with said gear portion, at least one of said arms being interconnected to said movable element.

Claim 13

A display device comprising: a base plate having a display panel on one side, said base plate having at least one opening therethrough and a pair of interengaged movable members mounted thereon; at least one movable element disposed on the display panel, said element being coupled to at least one of said members through at least one of said openings for relative movement therewith; wire means having one end fixed to one of said members adapted to contract upon the application of an electrical current thereto; pulsed electronic means engaging said wire means adapted to selectively apply pulsed electrical current to said wire means thereby contracting said wire means pulling said one of said members thereby moving both said one of said members and the other of said members interengaged therewith moving said movable element connected thereto; and a transparent cover closing off the front side of said panel and a back cover closing off said base plate, and a switch mounted in said back cover electrically coupled to said electronic means.

Claim 14

A display device comprising: a base plate having a display panel on one side, said base plate having at least one opening therethrough and a pair of interengaged movable members mounted thereon; at least one movable element disposed on the display panel, said element being coupled to at least one of said members through at least one of said openings for relative movement therewith; wire means having one end fixed to one of said members adapted to contract upon the application of an electrical current thereto; pulsed electronic means engaging said wire means adapted to selectively apply pulsed electrical current to said wire means thereby contracting said wire means pulling said one of said members thereby moving both said one of said members and the other of said members interengaged therewith moving said movable element connected thereto; and a transparent cover closing off the front side of said panel and a back cover closing off said base plate, and a switch mounted in said back cover electrically coupled to said electronic means.
