41	Drive shaft configuration for a high voltage antenna tuning mechanism	US33092673	1973-02-09	US3831399A	1974-08-27	MAJKRZAK C; SLADOWSKI S
There is disclosed dielectric material drive shaft constructions designed for use particularly in high electric-field potential environments such as in driven tuning mechanism of a high voltage helical transmitting antenna, which shaft constructions are capable of maintaining operation under unusually high mechanical loads requiring both rotational and axial movement. A plurality of elongated common-stock pieces of layered epoxy or siliconbonded fiberglass are shaped cross-sectionally to be united predeterminably into a unitary form via longitudinally running bonds of epoxy adhesive. The unitary form cross-section is a ''''soft'''' polygon, for example a rounded-off triangle or square, wherein the individual pieces are so arranged as to have the interlaminar shear planes of the layered dielectric material substantially perpendicular to the direction of the force of the applied loads. To provide a shaft surface which resists wear, prevents surface contamination, and has nontracking properties most beneficial in preventing arcing and creepage in extremely high potential electric gradient environments, a sleeve or jacket of teflon is provided about the shaft''s outer surface. In cases where shafts loads are excessive, the shaft construction may include a multiplicity of strong dielectric pins driven thru the unitary structure, each across a successive interfacing epoxy bond, to form a helical pin configuration which resist interlaminar shear loads and provides additional strength to these bonds.
42	Integrally-wound antenna helix-coilform	US32977673	1973-02-05	US3828353A	1974-08-06	MAJKRZAK C; POLGAR M
This concerns the fabrication of an integrally-wound helixcoilform assembly for an antenna of, for example, the high voltage and high power tunable helix-cylinder (inductance/capacitance) monopole type. Preassembled on a collapsible, cylindrically-shaped mandrel are a wound helix of controlled pitch, an end coupling to which the helix is affixed at one end, and a binding post securing the other end of the helix wire. After the entire assembly is enclosed in a plastic covering such as teflon shrink tubing or adhesive-backed tape helically wound to a predetermined tension and pattern, cycloaliphatic epoxy resin-saturated glass fibers are wound in a carefully controlled manner over the entire assembly in a predetermined pattern and then cured. The tensioned plastic covering together with the controlled winding of glass fibers provides for the interlaminar shear faces of the coilform structure type to be formed as convolutions between the helix turns, thus giving rise to an integrally-constructed assembly far superior both structurally and electrically.
