Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
Laser apparatus for use in operations with explosion hazard having a cylindrical metal housing having a beam exit end and an opposite electrical power supply end, a discharge tube coaxially arranged in the housing intermediate the beam exit and power supply ends, electronic power supply components coaxially arranged in the housing in the area of the power supply end, and an optical lens system mounted in the housing at the beam exit end of the housing, said laser apparatus comprising a body transparent to the laser beam mounted in the housing in a pressure-tight manner at the beam exit end thereof; another body having a feed-through for a connecting cable mounted in the housing at the power supply end in a pressure-tight manner; and a terminal feed-through cap covering the power supply end of the housing.
Claim 2
Dependent Claim
136 words
Laser apparatus for use in operations with explosion hazard having a cylindrical metal housing having a beam exit end and an opposite electrical power supply end, a discharge tube coaxially arranged in the housing intermediate the beam exit and power supply ends, electronic power supply components coaxially arranged in the housing in the area of the power supply end, and an optical lens system mounted in the housing at the beam exit end of the housing, said laser apparatus comprising a body transparent to the laser beam mounted in the housing in a pressure-tight manner at the beam exit end thereof; another body having a feed-through for a connecting cable mounted in the housing at the power supply end in a pressure-tight manner; and a terminal feed-through cap covering the power supply end of the housing.
Claim 3
Dependent Claim
34 words
Laser apparatus as claimed in claim 1, further comprising ring grooves formed in the housing, and securing rings inserted in the ring grooves for holding the body and the other body in the housing.
Claim 4
Dependent Claim
62 words
Laser apparatus as claimed in claim 2, further comprising a substantially annular insert in the housing at the power supply end thereof having a hold formed therethrough for accommodating the connecting cable, a strap cooperating with the annular insert for providing a tension relief for the connecting cable, and bolts accessible from the outside for affixing the cap to the annular insert.
Claim 5
Dependent Claim
46 words
Laser apparatus as claimed in claim 3, wherein the housing has a projecting portion at its power supply end and the cap has a recess formed therein and cooperating with the projecting portion of the housing to prevent mutual rotation of said cap and said housing.
