Abstract
Abstract A base element (10) is fixedly mounted to a microscope. The upper surface (18) of an annular mounting portion (15) at the top of base element (10) is flat and forms a track which extends around the vertical centerline, i.e. the optical axis of the microscope. Movably secured to the upper surface (18) of the annular mounting portion (15) is a positioner element (28). The positioner element (28) includes a portion (46) which is movable toward and away from the centerline of the microscope (12). On the top surface of the movable portion (46) is a translator element (64) which is rotatable relative to the positioner element (28). A micromanipulator (73), which is a microscope accessory, is mountable on the translator (64). The apparatus as a whole provides a stable platform for support and movement of a plurality of micromanipulators.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
An apparatus for use with a microscope for mounting one or more micromanipulators capable of carrying an electrical probe or the like, comprising: a base element supported so that it is stable relative to a microscope, the microscope including a microscope stage portion on which is mounted an article being investigated, said base element being physically separate from and independent of the microscope stage portion and including a track portion which extends around a substantial portion of the microscope stage portion; at least one positioning element removably mounted on the track portion of said base element so that, in operation, said positioning element can be moved along said track portion and conveniently mounted on and removed from the track portion, said base element being configured and arranged so as to receive a variable number of positioning elements, each positioning element including a portion thereof which is movable relative to the remainder of the positioning element, toward and away from the microscope stage portion; and means on said movable portion of said positioning element for supporting a micromanipulator, wherein the means for supporting a micromanipulator is rotatable relative to said movable portion; wherein said positioning element is mounted on the base element such that the base element is beneath and thereby directly supports said positioning means and the micromanipulator located thereon.
Claim 2
Independent Claim
220 words
An apparatus for use with a microscope for mounting one or more micromanipulators capable of carrying an electrical probe or the like, comprising: a base element supported so that it is stable relative to a microscope, the microscope including a microscope stage portion on which is mounted an article being investigated, said base element being physically separate from and independent of the microscope stage portion and including a track portion which extends around a substantial portion of the microscope stage portion; at least one positioning element removably mounted on the track portion of said base element so that, in operation, said positioning element can be moved along said track portion and conveniently mounted on and removed from the track portion, said base element being configured and arranged so as to receive a variable number of positioning elements, each positioning element including a portion thereof which is movable relative to the remainder of the positioning element, toward and away from the microscope stage portion; and means on said movable portion of said positioning element for supporting a micromanipulator, wherein the means for supporting a micromanipulator is rotatable relative to said movable portion; wherein said positioning element is mounted on the base element such that the base element is beneath and thereby directly supports said positioning means and the micromanipulator located thereon.
Claim 3
Dependent Claim
25 words
An apparatus of claim 1, wherein said track portion is configured such that it remains the same distance from the optical axis of the microscope.
Claim 4
Dependent Claim
31 words
An apparatus of claim 1, wherein said track portion is horizontal and wherein the plane of movement of said movable portion of said positioning element and said support means is horizontal.
Claim 5
Dependent Claim
16 words
An apparatus of claim 1, wherein said base element is fixedly supported by the microscope itself.
Claim 6
Dependent Claim
40 words
An apparatus of claim 1, wherein said track portion of said base element extends substantially completely about the optical axis of the microscope and wherein the microscope stage portion is in the vicinity of the optical axis of the microscope.
Claim 7
Dependent Claim
48 words
An apparatus of claim 1, wherein said movable portion of said positioning element comprises an upper portion of said positioning element, and includes a tenon part on the lower surface thereof which dovetails with a mortise part on the upper surface of the remainder of said positioning element.
Claim 8
Dependent Claim
21 words
An apparatus of claim 1, including means for clamping said movable portion of said positioning element relative to the remainder thereof.
Claim 9
Dependent Claim
30 words
An apparatus of claim 1, wherein said support means is rotatable for 360 degrees and wherein the apparatus includes means for clamping the support means in a selected angular position
Claim 10
Dependent Claim
39 words
An apparatus of claim 8, including a circular element which extends upwardly from the top surface of said movable portion of said positioning element, wherein said support means is mounted about said circular element and rotates thereabout in operation.
