Claim 3

Dependent Claim 49 words

The invention as set forth in claim 1 wherein said adjusting surface means has an abutting surface and said adjustment means slidably abuts said abutting surface whereby said adjustment means is capable of sliding movement substantially in the plane of said abutting surface means in at least one direction.

Claim 4

Dependent Claim 102 words

The invention as set forth in claim 1 wherein said pivotally connecting means comprises a centerpost and an annular receptacle, said annular receptacle having a pivoting surface and being attached to said optical element mount, said centerpost being in sliding engagement with said support element and having an outwardly extending flange which fits within said annular receptacle such that when said pivotally connecting means is in said non-locking mode, the annular receptacle pivots about the outwardly extending flange, and when said pivotally connecting means is in said locking mode, said outwardly extending flange forcefully engages, said pivoting surface of said annular receptacle.

Claim 5

Dependent Claim 49 words

The invention as set forth in claim 3 wherein said outwardly extending flange defines a portion of a spherical surface and wherein said optical mount has a mirror attached thereto such that the center of the curvature of the spherical surface substantially coincides with the surface of the mirror.

Claim 6

Dependent Claim 68 words

The invention as set forth in claim 3 wherein said centerpost has threads thereon and said locking means is a lock nut in threaded engagement therewith such that as said lock nut is moved inwardly towards said optical element mount said centerpost is caused to move axially such that said outwardly extending flange forcefully engages said pivoting surface so as to lock said optical element mount in place.

Claim 7

Dependent Claim 55 words

The invention set forth in claim 1 wherein said adjustment means comprises a plurality of threaded rod means for facilitating adjustment, said threaded rod means extending into and being in threaded engagement with said support element such that the turning of the threaded rod means will effect the angular positioning of the optical element mount.

Claim 8

Dependent Claim 48 words

The invention as set forth in claim 6 including an optical element supported by said optical element mount and wherein said plurality of threaded rod means are substantially equally spaced radially from the center of said optical element mount as well as being equally spaced from each other.

Claim 9

Dependent Claim 100 words

The invention as set forth in claim 6 wherein each of said threaded rod means has a protrusion on its end and wherein said adjusting surface means includes slot means for allowing limited movement in the radial direction relative to the center of said optical element mount, such that said protrusions on said threaded rod means engage the slot means of said adjusting surface means whereby the movement of the protrusions in the slot means is substantially confined to radial movement relative to the center of the optical element mount to thereby facilitate angular adjustment of said optical element mount.

Claim 10

Dependent Claim 65 words

The invention as set forth in claim 3 wherein said centerpost is tubular and said optical element mount has an aperture therein at least partially coinciding with the tubular opening of the centerpost such that light passing through said centerpost will also pass through said aperture in said optical element mount, said aperture having a reticle therein to facilitate alignment of said optical element mount.

Claim 11

Dependent Claim 121 words

The invention as set forth in claim 6 wherein said threaded rod means comprises a primary threaded rod and a secondary threaded rod, said primary threaded rod having two ends, said protrusion being on its first end and external threads being on its second end, said secondary threaded rod also having first and second ends, said first end of said secondary threaded rod being tubular and having external and internal threads the internal threads of said secondary threaded rod being in threaded engagement with the external threads of said primary threaded rod, said support element having a plurality of threaded apertures, said external threads of said secondary threaded rod being in threaded engagement with a threaded aperture of said support element.

Claim 12

Dependent Claim 32 words

The invention as set forth in claim 10 wherein the external threads of said secondary threaded rods and the external threads of said primary threaded rods have different threads per inch ratios.

Claim 13

Dependent Claim 88 words

The invention as set forth in claim 2 wherein said optical element mount has a rearward surface facing said support element which in conjunction with the portion of said adjusting surface means which contains the abutting surface defines an open space such that when said pivotally connecting means is in said locking mode and force is induced by said adjustment means against said abutting surface, said adjusting surface mans may flex into said open space without effecting the angular position or causing distortion of said optical element mount.

Claim 14

Independent Claim 159 words

A device for pivotally supporting an element comprising: a support frame; a centerpost axially slidable within said support frame; an element mount pivotally supported on said centerpost; said centerpost having a flange at one end and a threaded portion at the opposite end; said mounting element having an annular receptacle defining a surface which slidably engages said centerpost flange; said element mount including means for providing an adjusting surface capable of limited flexure relative to the mounting element; adjustment means extending from said support frame to said adjusting surface means for adjusting the angular position of said mounting element; a lock nut in threaded engagement with the threaded portion of said centerpost, whereby when said lock nut is tightened against said support frame said flange of said centerpost frictionally engages said surface of said annular receptacle and forces the adjusting surface means against the adjustment means thereby preventing pivotal movement of said mounting element relative to said support frame.

Claim 15

Independent Claim 159 words

A device for pivotally supporting an element comprising: a support frame; a centerpost axially slidable within said support frame; an element mount pivotally supported on said centerpost; said centerpost having a flange at one end and a threaded portion at the opposite end; said mounting element having an annular receptacle defining a surface which slidably engages said centerpost flange; said element mount including means for providing an adjusting surface capable of limited flexure relative to the mounting element; adjustment means extending from said support frame to said adjusting surface means for adjusting the angular position of said mounting element; a lock nut in threaded engagement with the threaded portion of said centerpost, whereby when said lock nut is tightened against said support frame said flange of said centerpost frictionally engages said surface of said annular receptacle and forces the adjusting surface means against the adjustment means thereby preventing pivotal movement of said mounting element relative to said support frame.

Claim 16

Dependent Claim 17 words

The invention as defined in claim 13 wherein said adjustment means include a plurality of threaded rods.

Claim 17

Dependent Claim 47 words

The invention as defined in claims 13 or 14 wherein said adjusting surface means comprises an abutment surface and said adjustment means includes an abutment end, said abutment end slidably engaging said abutment surface and capable of movement across said abutment surface in at least one direction.

Claim 18

Dependent Claim 44 words

The invention as defined in claim 15 wherein said abutment surface is located in an indented slot in said adjusting surface means, said slot extending in a radial direction whereby said abutment end may slide along said abutment surface only in a radial direction.
