Abstract
Abstract A motion responsive electrical control apparatus for emitting an electrical control signal incrementally variable in desired correlation to a path of given mechanical motion. The apparatus includes a rotatably regulated electrical controller for emitting signals correlated to the angular position setting of the controller regulator. A cam member pivotally mounted onto the regulator of the controller is arcuately biased into overlying engagement with a movable follower defining a motion path to which the apparatus is to respond. Presettably adjustable pitch members incrementally spaced along the path of follower motion effect desired incremental changes in cam pitch thereat affording corresponding change to the controller position setting.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
Electrical control apparatus comprising in combination: a. rotatably regulated electrical control means (adapted to emit a control signal correlated to its position setting;) b. cam means having an extended cam surface (adapted to engage a moving follower defining a motion path,) said cam means being secured to the rotatAble regulator of said control means for arcuate movement effective to change the position setting of said control means; and c. variably presettable means to adjustably preset the pitch of said cam surface for effecting a desired control signal correlated to the motion path of a moving follower with which it is adapted to engage.
Claim 2
Dependent Claim
103 words
Electrical control apparatus comprising in combination: a. rotatably regulated electrical control means (adapted to emit a control signal correlated to its position setting;) b. cam means having an extended cam surface (adapted to engage a moving follower defining a motion path,) said cam means being secured to the rotatAble regulator of said control means for arcuate movement effective to change the position setting of said control means; and c. variably presettable means to adjustably preset the pitch of said cam surface for effecting a desired control signal correlated to the motion path of a moving follower with which it is adapted to engage.
Claim 3
Dependent Claim
30 words
A control apparatus according to claim 1 in which said cam means is of a generally flexible composition secured to said presettable means and geometrically responsive to adjustable settings thereof.
Claim 4
Dependent Claim
38 words
A control apparatus according to claim 2 in which said variably presettable means comprises a plurality of individual pitch setting members incrementally spaced along the defined path of motion and individually adjustable in a lateral direction relative thereto.
Claim 5
Dependent Claim
48 words
A control apparatus according to claim 3 in which said cam means comprises an extending thin flexible wire at least spanning the motion path of a follower with which it is adapted to engage and secured to each of said pitch setting members at a reference location thereon.
Claim 6
Dependent Claim
46 words
A control apparatus according to claim 4 in which said individual pitch setting members are elongated of predetermined length adjustably positionable for securement to a pivotal support and said cam means is secured to each of said pitch setting members at a common terminal end thereof.
Claim 7
Dependent Claim
43 words
A control apparatus according to claim 4 in which said electrical control means comprises a variable electrical resistance adapted for connection to an electrical circuit associated with the moving follower for providing resistance values to the circuit correlated to its rotatably set position.
Claim 8
Dependent Claim
53 words
A control apparatus according to claim 5 in which said electrical control means comprises a variable electrical resistance adapted for connection to an electrical circuit associated with the moving follower, said control means having a rotatable adjustment regulator to which said pitch setting members support is secured for defining the pivot axis thereof.
