An auto rack sidewall bumper guard device for auto rack railroad cars eliminates contact between a vehicle door and the sidewalls. The bumper guard device includes a mounting plate and a plurality of horizontally extending vertically spaced-apart relatively low profile bumpers extending from the mounting plate. The mounting plate is adapted to cover the sidewall panel and part of each adjacent vertical posts to prevent the vehicle doors from contacting the sidewall panels and vertical posts.

The apparatus of claim 1, wherein the electrode is a helical coil. 3. The apparatus of claim 1, wherein the electrode is formed in the shape of a curvilinear winding. 4. The apparatus of claim 1, wherein in the imbedded electrode is formed in the shape of a curvilinear winding with reversals in direction. 5. In an electrical connector, combination filter-seal assembly of a monolithic combination electrical low-pass radio frequency absorbent filter and mechanical gas-tight seal apparatus, said filter-seal assembly comprising an electrically conductive metallic casing having a passageway therethrough and an interior wall, at least one metallic electrode extending through said passageway and not contacting said casing, and a solid plug means of ceramic material for attenuating high frequency electrical signals and for blocking the passage of gas through the passageway, said attenuating and blocking means including a solid electromagnetically lossy ceramic substantially gas-impermeable plug fused to the interior wall of said casing passageway and said electromagnetically lossy substantially gas-impermeable plug being fused to said electrode so as to embed said electrode within said plug and completely span the remaining free cross section of said passageway, including a mechanical and chemically bonded gas-tight fusion joint between the plug and the metallic casing; and a mechanically and chemically bonded gas-tight fusion joint between the plug and the electrodes; thereby forming a gas-tight electromagnetically lossy seal said plug being electromagnetically lossy and gas-impermeable. ds generally axially of the charge. 16.
