Abstract
A control apparatus for a work object, the control apparatus having a pair of substantially contrarotating members operable to define a selected relationship designated by the relationship of the members relative to each other; and an assembly for mounting the substantially contrarotating members in controlling relation to the work object whereby the selected relationship is operable to control the work object.
Claims13
A control apparatus for a work object comprising a pair of members operably interconnected for rotation about a substantially common axis of rotation;
- gear means interconnecting said members for transmitting rotational movement about said axis of rotation between said members whereby when one of the members of said pair of members is rotated in one direction substantially about said axis of rotation, the other member of said pair of members is rotated by said gear means in the opposite direction substantially about said axis of rotation substantially the same distance to define a selected relationship;
- and means for mounting said members in visibly exposed relation on and in controlling relation to said work object whereby said selected relationship is operable to control said work object and is visible to display said selected relationship.
A control apparatus for a work object, the control apparatus comprising a pair of substantially contrarotating members operably interconnected in a substantially contrarotating relationship about a substantially common axis of rotation to define a selected relationship;
- gear means operably interconnecting said members for transmitting rotational movement between said members whereby when one of the members of said pair of members is rotated in one direction substantially about said axis of rotation, the other member of said pair of members is rotated by said gear means in the opposite direction substantially about said axis of rotation substantially the same distance;
- means for mounting said substantially contrarotating members in controlling relation to said work object whereby said selected relationship is operable to control said work object;
- and locking means substantially preventing said substantially contrarotation of the pair of members until said locking means has been deployed in a predetermined attitude.

- gear means operably interconnecting said members for transmitting rotational movement between said members whereby when one of the members of said pair of members is rotated in one direction substantially about said axis of rotation, the other member of said pair of members is rotated by said gear means in the opposite direction substantially about said axis of rotation substantially the same distance;
- means for mounting said substantially contrarotating members in controlling relation to said work object whereby said selected relationship is operable to control said work object;
- and indicator means mounted on one of said substantially contrarotating members and disposed to display said selected relationship during said movement of the substantially contrarotating members.
