Abstract
Abstract The particular embodiment described herein as illustrative of one form of the invention utilizes a magnetically actuated reed switch arranged in coincidence with a flux path of an electromagnetically operated valve, which reed switch is actuated when the valve is moved to one of its selectively operable positions, and thereby changes a characteristic of the flux path, the actuation of the reed switch being in response to the change in the flux path characteristic.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
An apparatus for detecting the operation of a control device comprising: control means movable between first and second operating positions; a first magnetic flux path formed by the movement of said control means to one of said positions; a second magnetic flux path formed by the movement of said control means to the other of said positions; and magnetically actuated means responsive to the forming of one of said first and second magnetic flux paths for changing the characteristics of an electrical circuit and thereby providing an indication of the movement of the control means.
Claim 2
Independent Claim
95 words
An apparatus for detecting the operation of a control device comprising: control means movable between first and second operating positions; a first magnetic flux path formed by the movement of said control means to one of said positions; a second magnetic flux path formed by the movement of said control means to the other of said positions; and magnetically actuated means responsive to the forming of one of said first and second magnetic flux paths for changing the characteristics of an electrical circuit and thereby providing an indication of the movement of the control means.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1 wherein said magnetically actuated means is a reed switch.
Claim 4
Dependent Claim
36 words
The apparatus of claim 2 wherein said reed switch has elongated members with overlapping end portions movable into contact with one another, said elongated members having their longitudinal axis aligned parallel with said magnetic flux paths.
Claim 5
Dependent Claim
129 words
In a fluid flow control device having a valve movable between first and second operating positions and an electromagnetic system with first and second coils for forming first and second flux paths to operate the valve, an improved means for operating and detecting the operation of the fluid flow control device, which means comprises: first electronic gate means for passing a current to one of said first and second coils to form the first flux path; second electronic gate means for passing a current to other of said first and second coil to form the second flux path; and magnetically actuated means operable in response to the forming of a selected one of the first and second flux paths for providing an indication of the operation of the valve.
Claim 6
Dependent Claim
129 words
In a fluid flow control device having a valve movable between first and second operating positions and an electromagnetic system with first and second coils for forming first and second flux paths to operate the valve, an improved means for operating and detecting the operation of the fluid flow control device, which means comprises: first electronic gate means for passing a current to one of said first and second coils to form the first flux path; second electronic gate means for passing a current to other of said first and second coil to form the second flux path; and magnetically actuated means operable in response to the forming of a selected one of the first and second flux paths for providing an indication of the operation of the valve.
Claim 7
Dependent Claim
43 words
The apparatus of claim 4 and further including third electronic gate means operable in response to the operation of said magnetically actuated means for supplying power to a device signalling the forming of the selected one of the first and second flux paths.
Claim 8
Dependent Claim
43 words
The apparatus of claim 5 wherein saId magnetically actuated means is a reed switch having elongated portions for contacting one another and arranged in parallel with and in the field of influence of the selected one of the first and second flux paths.
Claim 9
Independent Claim
129 words
An apparatus for detecting the operation of an electromagnetically operated system which has a valve element movable between operable positions by energization of one of two magnetic flux paths of the valve system comprising: a reed switch having members arranged in an overlapping manner an spaced from one another, said reed switch being positioned on said valve system so that the longitudinal axis of said members are in coincidence with one of the valve system flux paths, said reed switch members being arranged to come into contact with one another in response to energization of said one of the magnetic flux paths of the valve system; and electrically operated means responsive to the contact of said members for providing a signal indicative of the change in the flux path.
Claim 10
Independent Claim
129 words
An apparatus for detecting the operation of an electromagnetically operated system which has a valve element movable between operable positions by energization of one of two magnetic flux paths of the valve system comprising: a reed switch having members arranged in an overlapping manner an spaced from one another, said reed switch being positioned on said valve system so that the longitudinal axis of said members are in coincidence with one of the valve system flux paths, said reed switch members being arranged to come into contact with one another in response to energization of said one of the magnetic flux paths of the valve system; and electrically operated means responsive to the contact of said members for providing a signal indicative of the change in the flux path.
