Abstract
Abstract Apparatus for transmitting a beam of energy includes a first arm formed by a hollow tube, which is rotatable about its own axis, a second arm formed by two half-arms, arranged symmetrically with respect to the axis of the first tube and movable with respect thereto by means of an articulation, and a third arm formed by a hollow tube, articulated to the half-arms by two intermediate parts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
230 words
An apparatus for transmitting a beam of energy said apparatus comprising: a first arm comprising a hollow tube having a longitudinal axis, said arm being disposed for rotation about said axis; first reflecting means disposed within said tube so as to reflect said beam along said longitudinal axis; a second arm comprising a first half arm and a second half arm having the same weight, said half arms being symmetrical of each other with respect to a plane containing the longitudinal axis of said first arm and at least said first half arm being hollow; at least one intermediate part connecting said second arm to said first arm so that said second arm may rotate with respect to said first arm about an axis perpendicular to the longitudinal axis of the first arm and encountering the latter; second reflecting means for transmitting the beam reflected by said first reflecting means within said first half arm; a third arm comprising a hollow tube having a longitudinal axis; at least one intermediate member connecting said third arm to said second arm so that said third arm may rotate with respect to said second arm about an axis perpendicular to the longitudinal axis of said third arm; and third reflecting means for deviating the beam circulating within said first half arm so that it coincides with the longitudinal axis of said third arm.
Claim 2
Independent Claim
230 words
An apparatus for transmitting a beam of energy said apparatus comprising: a first arm comprising a hollow tube having a longitudinal axis, said arm being disposed for rotation about said axis; first reflecting means disposed within said tube so as to reflect said beam along said longitudinal axis; a second arm comprising a first half arm and a second half arm having the same weight, said half arms being symmetrical of each other with respect to a plane containing the longitudinal axis of said first arm and at least said first half arm being hollow; at least one intermediate part connecting said second arm to said first arm so that said second arm may rotate with respect to said first arm about an axis perpendicular to the longitudinal axis of the first arm and encountering the latter; second reflecting means for transmitting the beam reflected by said first reflecting means within said first half arm; a third arm comprising a hollow tube having a longitudinal axis; at least one intermediate member connecting said third arm to said second arm so that said third arm may rotate with respect to said second arm about an axis perpendicular to the longitudinal axis of said third arm; and third reflecting means for deviating the beam circulating within said first half arm so that it coincides with the longitudinal axis of said third arm.
Claim 3
Independent Claim
25 words
An apparatus according to claim , 1 wherein at least one of the arms other than the first arm is equipped with a balancing counterweight.
Claim 4
Dependent Claim
26 words
An apparatus according to claim 2, further comprising at least one motor means for displacement of one of the arms with respect to an adjacent arm.
Claim 5
Dependent Claim
14 words
An apparatus according to claim 11, wherein the motor means serves as a counterweight.
Claim 6
Independent Claim
21 words
An apparatus according to claim , 1 wherein the tube forming the third arm of the apparatus moves about its axis.
Claim 7
Dependent Claim
41 words
An apparatus according to claim 1, further comprising a fourth arm of limited length connected to the third arm by an articulation incorporating an intermediate part, said articulation having at least one mirror forming an angle of 45° with the beam.
Claim 8
Dependent Claim
43 words
An apparatus according to claim claim 1, further comprising a fourth arm formed by two half arms and connected to the third arm by an articulation and a fifth arm formed in one piece and connected to the fourth arm by an articulation.
Claim 9
Independent Claim
20 words
An apparatus according to claim , 1 wherein at least one of the mirrors is equipped with a cooling system.
Claim 10
Dependent Claim
15 words
A apparatus according to claim 1, further comprising a lens for focusing said energetic beam.
