Abstract
Abstract A streamlined, gas discharge, anti-collision aircraft beacon for high speed aircraft which is adapted for mounting on an external portion of the aircraft, and which includes a generally inverted U-shaped gas discharge tube to provide light through 360* in a horizontal plane and 180* in a vertical plane. Two concave reflectors positioned concentrically with the horizontal elongated portion of the gas discharge tube so as to increase the intensity of light projected in the fore and aft directions of an airplane. An aerodynamically streamlined design light transmitting cover over the reflectors and gas discharge tube is provided to reduce aerodynamic drag on the aircraft.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A streamlined, gas discharge, anti-collision aircraft beacon for mounting on an external portion of an aircraft comprising: a gas discharge tube means for supplying a light field about the beacon, said gas discharge tube means having a generally horizontally disposed elongated portion; two concave reflectors having inner concave reflective surfaces defining separate focal points, the reflectors opening toward opposite directions and being positioned so that said tube means pass through said focal points, a streamlined light transmitting cover over said reflectors and tube means having a generally tear-drop configuration elongated in alignment with the tube means, lighting circuitry for stroboscopically flashing said gas discharge tube means.
Claim 2
Dependent Claim
106 words
A streamlined, gas discharge, anti-collision aircraft beacon for mounting on an external portion of an aircraft comprising: a gas discharge tube means for supplying a light field about the beacon, said gas discharge tube means having a generally horizontally disposed elongated portion; two concave reflectors having inner concave reflective surfaces defining separate focal points, the reflectors opening toward opposite directions and being positioned so that said tube means pass through said focal points, a streamlined light transmitting cover over said reflectors and tube means having a generally tear-drop configuration elongated in alignment with the tube means, lighting circuitry for stroboscopically flashing said gas discharge tube means.
Claim 3
Dependent Claim
41 words
An aircraft beacon as defined in claim 1 wherein said gas discharge tube means has end portions vertically disposed in a plane aligned with the elongation of the cover and having means at its extremities removably attached to said lighting circuitry.
Claim 4
Dependent Claim
67 words
An aircraft beacon as defined in claim 1 wherein said reflectors are disposed in a spaced relation to each other and have elongated slot means extending from their outer peripheral edges into their respective central region for permitting radial movement for installation and removal of said reflector from said tube means and for positioning said reflector so as to reflect light fore and aft of the beacon.
Claim 5
Dependent Claim
16 words
An aircraft beacon as defined in claim 3 wherein said reflectors have a parabolic-shaped reflecting surface.
Claim 6
Dependent Claim
41 words
An aircraft beacon as defined in claim 3 wherein said gas discharge tube means has end portions vertically disposed in a plane aligned with the elongation of the cover and having means at its extremities removably attached to said lighting circuitry.
Claim 7
Dependent Claim
16 words
An aircraft beacon as defined in claim 3 wherein said reflectors respectively have elliptical reflecting surfaces.
