Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A corona generating device, including a coronode connected between mountings, at least one of which comprises a fixed member and a movable member, to which the associated end of the coronode is attached, said members interacting through compressible resilient means which act to urge the movable member in the direction of the adjacent end of the device, said fixed member being generally channel-shaped in cross-section, said channelshaped cross-section being defined by side walls extending from a common bridging wall in a direction away from said adjacent end, the resilient means being arranged in recesses in the side walls of said fixed member and said movable member having lateral lugs which engage the resilient means.
Claim 2
Dependent Claim
114 words
A corona generating device, including a coronode connected between mountings, at least one of which comprises a fixed member and a movable member, to which the associated end of the coronode is attached, said members interacting through compressible resilient means which act to urge the movable member in the direction of the adjacent end of the device, said fixed member being generally channel-shaped in cross-section, said channelshaped cross-section being defined by side walls extending from a common bridging wall in a direction away from said adjacent end, the resilient means being arranged in recesses in the side walls of said fixed member and said movable member having lateral lugs which engage the resilient means.
Claim 3
Dependent Claim
14 words
A device as claimed in claim 1, wherein the resilient means comprises compression springs.
Claim 4
Dependent Claim
19 words
A device as claimed in claim 1, wherein relative position markers are provided on said fixed and movable members.
Claim 5
Dependent Claim
35 words
A device as claimed in claim 1 further including a channel shaped support having a plurality of recesses, and further wherein said fixed member has flanges which extend into said recesses in said support member.
Claim 6
Dependent Claim
57 words
The device claimed in claim 1 further including an elongated support member which is channel-shaped in cross-section, said support member having at least one recess adjacent one end thereof and further wherein said fixed member is carried in the channel in said support member adjacent said one end and includes a lug which interfits into said recess.
Claim 7
Dependent Claim
24 words
The combination recited in claim 1 wherein said side walls and bridging wall jointly form a recess in which said movable member is located.
