Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
118 words
A motion detecting apparatus for sensing when an object has ceased moving so that an associated machine will automatically stop comprising: a. a relay circuit which permits said machine to proceed past a cycle-stop position as long as said relay circuit is energized; b. means for deenergizing said circuit after said machine has proceeded past said cycle-stop position; and c. trigger circuit connected to said object and activated by the movement of said object for reenergizing said relay circuit before said machine again reaches said cycle-stop position, so that said relay circuit is alternately deenergized and reset by the sequential actions of said deenergizing means and said trigger circuit means as long as said object continues to move.
Claim 2
Dependent Claim
118 words
A motion detecting apparatus for sensing when an object has ceased moving so that an associated machine will automatically stop comprising: a. a relay circuit which permits said machine to proceed past a cycle-stop position as long as said relay circuit is energized; b. means for deenergizing said circuit after said machine has proceeded past said cycle-stop position; and c. trigger circuit connected to said object and activated by the movement of said object for reenergizing said relay circuit before said machine again reaches said cycle-stop position, so that said relay circuit is alternately deenergized and reset by the sequential actions of said deenergizing means and said trigger circuit means as long as said object continues to move.
Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein said object is a supply roll having rotational movement.
Claim 4
Dependent Claim
25 words
a silicon controlled rectifier which can be made conductive by a voltage pulse applied thereto and which becomes nonconductive when said relay circuit becomes deenergized;
Claim 5
Dependent Claim
25 words
a silicon controlled rectifier which can be made conductive by a voltage pulse applied thereto and which becomes nonconductive when said relay circuit becomes deenergized;
Claim 6
Dependent Claim
46 words
a second electric power source for sending a pulse of voltage to said silicon controlled rectifier when said motion sensing switch becomes nonconductive so that said relay circuit is alternately deenergized and energized in sequence as long as said material continues to feed to said machine.
Claim 7
Dependent Claim
46 words
a second electric power source for sending a pulse of voltage to said silicon controlled rectifier when said motion sensing switch becomes nonconductive so that said relay circuit is alternately deenergized and energized in sequence as long as said material continues to feed to said machine.
Claim 8
Dependent Claim
15 words
an electric power source for energizing said relay circuit when said rectifier is made conductive;
Claim 9
Dependent Claim
15 words
an electric power source for energizing said relay circuit when said rectifier is made conductive;
Claim 10
Dependent Claim
16 words
The apparatus of claim 1 wherein said object is sheet material being processed by said machine.
Claim 11
Dependent Claim
22 words
The apparatus of claim 3 wherein said relay circuit is energized at least once for each incremental movement of said sheet material.
Claim 12
Dependent Claim
42 words
a cycle reference switch for deenergizing said relay circuit after said machine has proceeded past said cycle-stop position; and b. a trigger pulse circuit for reenergizing said relay circuit before said machine reaches the next cycle-stop position, said circuit having in parallel:
Claim 13
Dependent Claim
42 words
a cycle reference switch for deenergizing said relay circuit after said machine has proceeded past said cycle-stop position; and b. a trigger pulse circuit for reenergizing said relay circuit before said machine reaches the next cycle-stop position, said circuit having in parallel:
Claim 14
Dependent Claim
52 words
A motion detecting appaRatus for sensing when sheet material has ceased being fed to a machine so that said machine will automatically stop comprising: a. a relay circuit having in series: l. a relay which permits said machine to proceed past a cycle-stop position as long as said relay circuit is energized;
Claim 15
Dependent Claim
52 words
A motion detecting appaRatus for sensing when sheet material has ceased being fed to a machine so that said machine will automatically stop comprising: a. a relay circuit having in series: l. a relay which permits said machine to proceed past a cycle-stop position as long as said relay circuit is energized;
Claim 16
Dependent Claim
26 words
The apparatus of claim 5 wherein said relay circuit is energized at least once by a trigger pulse for each incremental motion of said sheet material.
Claim 17
Dependent Claim
65 words
The motion detecting apparatus of claim 4 wherein said motion sensing switch comprises a pair of spaced concave metallic discs and a metallic ball which simultaneously makes physical and electrical contact with both discs only at the rims thereof, said ball falling out of and into contact with said discs as said switch is rotated so as to periodically interrupt electrical continuity between said discs.
Claim 18
Independent Claim
93 words
A method for sensing when an object has ceased moving so that an associated machine will automatically stop comprising: a. energizing a relay circuit to enable said machine to proceed past a cycle-stop position; b. deenergizing said circuit after said machine has proceeded past said cycle-stop position; c. sensing whether said object is moving and upon sensing movement of said object; and d. reenergizing said relay circuit before said machine reaches the next cycle-stop position so that said relay circuit is alternately deenergized and reenergized as long as said part continues to move.
Claim 19
Independent Claim
93 words
A method for sensing when an object has ceased moving so that an associated machine will automatically stop comprising: a. energizing a relay circuit to enable said machine to proceed past a cycle-stop position; b. deenergizing said circuit after said machine has proceeded past said cycle-stop position; c. sensing whether said object is moving and upon sensing movement of said object; and d. reenergizing said relay circuit before said machine reaches the next cycle-stop position so that said relay circuit is alternately deenergized and reenergized as long as said part continues to move.
Claim 20
Dependent Claim
14 words
