Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
75 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for raising and lowering said top; a platform parallel to and spaced above said top and adapted for low-friction multi-directional uniplanar movement in a plane parallel to said top; and a probe holder, adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions.
Claim 2
Dependent Claim
75 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for raising and lowering said top; a platform parallel to and spaced above said top and adapted for low-friction multi-directional uniplanar movement in a plane parallel to said top; and a probe holder, adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions.
Claim 3
Dependent Claim
33 words
The support table according to claim 1 including a shelf spaced above and parallel to said platform form and adapted for variable spacing away from said platform and releasable securement to said platform.
Claim 4
Dependent Claim
40 words
The support table according to claim 1 wherein said column includes: a pump adapted for raising said top; and a pressure release valve associated with said pump and adapted for releasing pressure in said pump whereby said top is lowered.
Claim 5
Dependent Claim
17 words
The support table according to claim 1 wherein said base includes a caster secured to said base.
Claim 6
Dependent Claim
22 words
The support table according to claim 1 further comprising limiting means adapted for limiting the movement of said platform on said top.
Claim 7
Dependent Claim
43 words
The support table according to claim 5 wherein said limiting means includes: a rod affixed to an upper surface of said top; and a retaining disk releaseably secured to said rod and adapted for limiting the movement of said platform on said top.
Claim 8
Dependent Claim
87 words
The support table according to claim 1 wherein said probe holder further comprises: an arm, a lower portion of said arm is adapted for a releasable, variable securement to said platform; a support block affixed to an upper portion of said arm; a first collar having a first bore, said first collar being joined to said support block and adapted for fixable, tiltable movement thereon; and a second collar having a second bore, said second collar fixable rotatably disposed within said first bore of said first collar.
Claim 9
Dependent Claim
31 words
The support table according to claim 7 wherein said arm includes a joint disposed between said lower portion and said upper portion and adapted for fixable pivotable adjustment of said arm.
Claim 10
Dependent Claim
155 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for lowering and raising said top; a platform parallel to and spaced above said top and adapted for low friction multi-directional uniplanar movement in a plane parallel to said top; a probe holder adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions; a bar defining a boundary of a compartment, said bar being affixed to said top; and a ball bearing matrix disposed within said compartment and including a plate having holes, a ball bearing being disposed within one of said holes and adapted for free rolling movement in said hole, whereby said ball bearing matrix engages said platform and said upper surface of said top thereby allowing the multi-directional uniplanar movement of said platform in the plane parallel to said top.
Claim 11
Dependent Claim
155 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for lowering and raising said top; a platform parallel to and spaced above said top and adapted for low friction multi-directional uniplanar movement in a plane parallel to said top; a probe holder adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions; a bar defining a boundary of a compartment, said bar being affixed to said top; and a ball bearing matrix disposed within said compartment and including a plate having holes, a ball bearing being disposed within one of said holes and adapted for free rolling movement in said hole, whereby said ball bearing matrix engages said platform and said upper surface of said top thereby allowing the multi-directional uniplanar movement of said platform in the plane parallel to said top.
Claim 12
Dependent Claim
166 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for lowering and raising said top; a platform parallel to and spaced above said top and adopted for low friction multi-directional uniplanar movement in a plane parallel to said top, wherein said platform comprises a top piece having a plurality of slots disposed along opposite edge portions of said top piece and an opening having a diameter and disposed through said top piece, a bottom piece parallel to and spaced from said top piece having a second opening having a diameter and aligned coaxially with said opening of said top piece, said diameter of said second opening greater than said diameter of said opening of said top piece, and a spacer affixed between said top piece and said bottom piece; and a probe holder adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions.
Claim 13
Dependent Claim
166 words
A support table comprising: a top; a base; an adjustable support column connecting said top and said base, said column adapted for lowering and raising said top; a platform parallel to and spaced above said top and adopted for low friction multi-directional uniplanar movement in a plane parallel to said top, wherein said platform comprises a top piece having a plurality of slots disposed along opposite edge portions of said top piece and an opening having a diameter and disposed through said top piece, a bottom piece parallel to and spaced from said top piece having a second opening having a diameter and aligned coaxially with said opening of said top piece, said diameter of said second opening greater than said diameter of said opening of said top piece, and a spacer affixed between said top piece and said bottom piece; and a probe holder adapted for releasable, variable securement to said platform, said probe holder being further adapted for securable, variable positioning in three dimensions.
Claim 14
Dependent Claim
15 words
