Abstract: A submarine periscope eyeguard housing assembly includes a viewing lens housing having a viewing lens aperture and viewing lens therein, first and second arm members fixed to the viewing lens housing and extending therefrom, a first blinder mounted on the first arm member, and a second blinder mounted on the second arm member. A first eyeguard is mounted on the first blinder for engagement by a left eye area of a viewer's head, and a second eyeguard is mounted on the second blinder for engagement by a right eye area of the viewer's head. A third eyeguard is rotatably mounted on the viewing lens housing and is adapted to be rotated into a selected one of a first position complementary to the first eyeguard and a second position complementary to the second eyeguard.

Abstract: In a lens assembly and housing therefor for use in conjunction with an optical apparatus, the lens assembly includes a lens frame of nonferrous material and defining a window having a lip therein along a periphery of the window, a lens disposed in the window and adjacent the lip, a pair of spaced magnets on the frame, and a grip formed on the frame. The housing includes first and second walls opposed to each other and in part defining a pocket, the first wall being nonferrous and the second wall being magnetically permeable, the pocket being adapted to receive the lens assembly with the grip of the frame extending beyond the pocket. The magnets interact with the magnetically permeable second wall of the pocket to releasably retain the lens assembly in the lens assembly housing.

Abstract: In combination, a male, multiple connection-type, electrical connector, a female, multiple connection-type, electrical connector, and a connector guide for facilitating blind interconnection of the male and female connectors. The male electrical connector comprises a submarine periscope eye box mating end electrical connector. The female electrical connector comprises a submarine periscope mast mating end electrical connector. The connector guide comprises a wall adapted to slidingly engage outside surfaces of the female connector, and an outwardly flared skirt extending from an edge of the guide wall opposed to the eye box mating end. The connector guide is slidable onto the female connector and the male connector is slidable into the connector guide and is guided thereinto by the connector guide skirt, and is guided by the connector guide into the female connector, such that the eye box connector elements engage the mast connector elements.

Abstract: An eyecup assembly for a submarine periscope blinder assembly includes an annularly-shaped ring having a multiplicity of holes, which are unthreaded, extending therethrough and adapted to receive screws for securing the eyecup assembly to a like multiplicity of holes which are threaded and arranged in a circular pattern around an eyepiece opening in the blinder assembly, the ring defining a central viewing opening. An eyecup lateral shell circumscribes the eyecup chamber and is fixed to the ring and configured to conform generally to an eye area of a viewer's head, and to be interchangeably mounted to the threaded holes to receive either the viewer's left or right eyes by selectively indexing the holes in the ring 180° apart relative to the threaded blinder assembly holes.

Abstract: A directional heat exchanger system dissipates heat generated by components contained within a thermally insulated antenna mounted atop a periscope be. A first wall of thermally conductive material has a first face and a second face with the first face being shaped to substantially contact an internal portion of the periscope tube. A plurality of ribs made from thermally conductive material are fixedly coupled to the second face. A second wall of thermally conductive material opposes the second face of the first wall and is in tangential contact with the ribs to form a fluid seal therewith. At least one channel is formed between the first and second walls. The end of each rib is offset from the end of adjacent ribs such that the channel defines a flow path having a first end and a second end. The components generating heat are thermally coupled to a heat pipe positioned partially in the antenna and partially in the periscope tube.
