Abstract
Abstract The indicator of this invention measures the amount of a web material wound upon a spool by utilizing the principle that the rate at which the spool rotates, as the web is wound or unwound therefrom, varies in proportion to the amount of the web material thereon. A pulse generator is provided for generating pulses which indicate the rotational velocity of the spool and a second pulse generator is provided for generating pulses which indicate the linear velocity of the web material. A counter counts the number of pulses generated by the linear web motion during each pulse generated by the rotating spool. The accumulated count is then stored and displayed for indicating the amount of the web material upon the spool.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
244 words
An indicating device for indicating the quantity of a thin flexible web member remaining upon a reel means, comprising: first pulse generating means associated with said reel means; guide roller means arranged for guiding said thin flexible web member to and from said means; second pulse generating means associated with said guide roller means; counting means; switching means for applying pulses from said second pulse generating means to said counting means between pulses from said first pulse generating means also applied thereto; display means associated with said counting means, said counting means including storage means arranged for storing said counted pulses from said second pulse generating means and applying said stored count to said display means upon receipt of a pulse from said first pulse generating means, thereby indicating the amount of said thin flexible web member remaining upon said reel means and additionally said gate means having a first gate for receiving pulses from said first pulse generating means and a second gate for receiving pulses from said first and second pulse generating means, said second gate arranged for pulsing said counting means with pulses from said second pulse generating means during a time period between pulses from said first pulse generating means, said first gate arranged for pulsing said storage means with pulses from said first pulse generating means to transfer said pulses from said counting means to said storage means for displaying the quantity of said pulses upon said display means.
Claim 2
Dependent Claim
244 words
An indicating device for indicating the quantity of a thin flexible web member remaining upon a reel means, comprising: first pulse generating means associated with said reel means; guide roller means arranged for guiding said thin flexible web member to and from said means; second pulse generating means associated with said guide roller means; counting means; switching means for applying pulses from said second pulse generating means to said counting means between pulses from said first pulse generating means also applied thereto; display means associated with said counting means, said counting means including storage means arranged for storing said counted pulses from said second pulse generating means and applying said stored count to said display means upon receipt of a pulse from said first pulse generating means, thereby indicating the amount of said thin flexible web member remaining upon said reel means and additionally said gate means having a first gate for receiving pulses from said first pulse generating means and a second gate for receiving pulses from said first and second pulse generating means, said second gate arranged for pulsing said counting means with pulses from said second pulse generating means during a time period between pulses from said first pulse generating means, said first gate arranged for pulsing said storage means with pulses from said first pulse generating means to transfer said pulses from said counting means to said storage means for displaying the quantity of said pulses upon said display means.
Claim 3
Dependent Claim
64 words
An indicating device as claimed in claim 1 additionally comprising present limiting means connected to said switching means for receiving said pulses generated by said second pulse generating means between said pulses generated by said first pulse generating means and arranged to generate a signal at a predetermined count corresponding with a predetermined position of said thin flexible web member upon said reel means.
Claim 4
Dependent Claim
20 words
An indicating device as claimed in claim 1 wherein said display means iNcludes means for displaying a binary coded decimal.
Claim 5
Dependent Claim
36 words
An indicating device as claimed in claim 1, wherein said display means includes means for generating a binary coded decimal signal and a digital to analogue converter means for providing an analogue display of said signal.
