Abstract
Abstract Apparatus for securing a fragile cylindrical tube within an envelope by using at least two spaced-apart mounting rings which tend to center the tube within the envelope. Each mounting ring is provided with three radially-extending through-holes, and an elastic sphere having a diameter greater than the thickness of the ring placed in each through-hole is in contact with the inner surface of the envelope and the outer surface of the tube, thus centering the tube within the envelope.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
Apparatus for securing a fragile cylindrical tube within a cylindrical envelope comprising at least two spaced apart mounting means disposed along the length of said tube and between said tube and said envelope, each of said mounting means comprising: (a) a ring-shaped holder having an inner diameter greater than the outer diameter of said tube, and an outer diameter smaller than the inner diameter of said envelope, said ring-shaped holder further being provided with three radially-oriented cylindrical through-holes, and (b) an elastic sphere disposed in each of said cylindrical through-holes for pressing against an outer portion of said tube and an inside portion of said envelope; whereby said tube is fixedly secured within said envelope.
Claim 2
Dependent Claim
115 words
Apparatus for securing a fragile cylindrical tube within a cylindrical envelope comprising at least two spaced apart mounting means disposed along the length of said tube and between said tube and said envelope, each of said mounting means comprising: (a) a ring-shaped holder having an inner diameter greater than the outer diameter of said tube, and an outer diameter smaller than the inner diameter of said envelope, said ring-shaped holder further being provided with three radially-oriented cylindrical through-holes, and (b) an elastic sphere disposed in each of said cylindrical through-holes for pressing against an outer portion of said tube and an inside portion of said envelope; whereby said tube is fixedly secured within said envelope.
Claim 3
Dependent Claim
114 words
Apparatus for securing a fragile cylindrical tube within a cylindrical envelope comprising at least two spaced apart mounting means disposed along the length of said tube and between said tube and said envelope, each of said mounting means comprising: (a) a ring-shaped holder having an inner diameter greater than the outer diameter of said tube, and an outer diameter smaller than the inner diameter of said envelope, said ring-shaped holder further being provided with three radially-oriented cylindrical through-holes, and (b) an elastic sphere disposed in each of said cylindrical through-holes; wherein said ring-shaped holders are provided with through-holes which are parallel to the axis thereof to provide passage for electrical leads and mechanical spacers.
Claim 4
Dependent Claim
114 words
Apparatus for securing a fragile cylindrical tube within a cylindrical envelope comprising at least two spaced apart mounting means disposed along the length of said tube and between said tube and said envelope, each of said mounting means comprising: (a) a ring-shaped holder having an inner diameter greater than the outer diameter of said tube, and an outer diameter smaller than the inner diameter of said envelope, said ring-shaped holder further being provided with three radially-oriented cylindrical through-holes, and (b) an elastic sphere disposed in each of said cylindrical through-holes; wherein said ring-shaped holders are provided with through-holes which are parallel to the axis thereof to provide passage for electrical leads and mechanical spacers.
Claim 5
Dependent Claim
45 words
Apparatus according to claim 1 or 2 in which each elastic sphere has a diameter greater than half of the difference between the inner diameter of the envelope and the outer diameter of the tube and smaller than the diameter of said radially-oriented cylindrical through-holes.
Claim 6
Dependent Claim
22 words
Apparatus according to claim 1 or 2 in which each of said elastic spheres is made of rubber, silicon rubber or plastic.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 1 or 2 in which said ring-shaped holder is made of an electrical insulating material.
Claim 8
Dependent Claim
