Abstract
Abstract Close observation of the controlled cutting action of a cutter operating at a remote location is achieved by providing a viewing means having a viewing part such as the optically exposed end of a fiberoptic filament positioned close to and movable with the cutting element, that viewing part being operatively connected to means at a remote station for making intelligible that which is viewed thereby. Preferably the viewing part is physically connected to the cutting element so as to be movable therewith, and the operative connection between the viewing part and the remote station comprises a TV camera and associated equipment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
In the combination of a cutting apparatus designed to operate at a remote location comprising a support movable along a surface to a cutting position and a power-driven cutting element operatively mounted on said support for movement relative to said support from an inoperative position through a series of cutting positions and means movable along said surface for viewing the cutting operation, the improvement which comprises said viewing means comprising a viewing part and a transmitting part, said viewing means being operatively connected to said cutting element so that said viewing part is closely spaced relative to, is pointed toward, and is essentially movable with said cutting element as the latter thus moves relative to said support, and mans operatively connected to said transmitting part for making intelligible at a remote station that which is viewed by said viewing part.
Claim 2
Dependent Claim
140 words
In the combination of a cutting apparatus designed to operate at a remote location comprising a support movable along a surface to a cutting position and a power-driven cutting element operatively mounted on said support for movement relative to said support from an inoperative position through a series of cutting positions and means movable along said surface for viewing the cutting operation, the improvement which comprises said viewing means comprising a viewing part and a transmitting part, said viewing means being operatively connected to said cutting element so that said viewing part is closely spaced relative to, is pointed toward, and is essentially movable with said cutting element as the latter thus moves relative to said support, and mans operatively connected to said transmitting part for making intelligible at a remote station that which is viewed by said viewing part.
Claim 3
Dependent Claim
17 words
The combination of claim 1 in which said viewing part is physically carried by said cutting element.
Claim 4
Dependent Claim
31 words
The combination of either of claims 1 or 2, in which said viewing means comprises a support movable along said surface, said transmitting part being mounted on said viewing means support.
Claim 5
Dependent Claim
28 words
In the combination of claim 3, an operative connection between said cutting apparatus support and said viewing means support for causing substantially simultaneous movement of said two supports.
Claim 6
Dependent Claim
28 words
The combination of either of claims 1 or 2, in which said viewing means comprises a fiberoptic element operatively connected between said viewing part and said transmitting part.
Claim 7
Dependent Claim
38 words
In the combination of claim 5, a fiberoptic illuminating means generally paralleling said viewing means fiberoptic element, said fiberoptic illuminating means having a light-emitting part adjacent to and essentially movable with said viewing part of said viewing means.
Claim 8
Dependent Claim
27 words
The combination of claim 6, in which said viewing means comprises a support movable along said surface, said transmitting part being mounted on said viewing means support.
Claim 9
Dependent Claim
28 words
In the combination of claim 7, an operative connection between said cutting apparatus support and said viewing means support for causing substantially simultaneous movement of said two supports.
Claim 10
Dependent Claim
50 words
The combination of claim 5, in which said fiberoptic element is located on said support, and camera means on said support, operatively connected to said transmitting part, and operatively connected to said remote station, thereby to make intelligible to said remote station that which is viewed by said viewing part.
Claim 11
Dependent Claim
28 words
In the combination of claim 9, an operative connection between said cutting apparatus support and said viewing means support for causing substantially simultaneous movement of said two supports.
Claim 12
Dependent Claim
39 words
In the combination of claim 10, fiberoptic illuminating means generally paralleling said viewing means fiberoptic element, said fiberoptic illuminating means having a light-emitting part adjacent to and essentially movable with said viewing part of said viewing means fiberoptic element.
Claim 13
Dependent Claim
39 words
In the combination of claim 9, fiberoptic illuminating means generally paralleling said viewing means fiberoptic element, said fiberoptic illuminating means having a light-emitting part adjacent to and essentially movable with said viewing part of said viewing means fiberoptic element.
