Abstract: A method for sewing a plurality of gore-shaped metalized mesh fabric panels to each other to form a parabolic dish-shaped reflector surface for subsequent attachment to the radially extendable rib members of a deployable parabolic reflector. The method includes using a template having "cut" and "sew" lines indicated thereon for cutting out a desired number of gore-shaped panels from a bolt of metalized mesh fabric and sewing the panels together along adjacent side edges thereof to form the dish-shaped reflector surface. The dish-shaped reflector surface is then attached to the reflector by sewing the mesh fabric panels to stitch holes provided in each rib member. The reflector surface is accurized by using a wedge-shaped tool which is placed on a slack reflector panel adjacent a gore seam.

Abstract: A redeployable, furlable rib reflector which is furlable and unfurlable between a first stowed position and a second deployed position. The reflector includes a hub assembly having spaced apart top and bottom plate members adapted to receive an antenna feed assembly mounted thereon and a plurality of attachable modular rib assemblies spaced about a periphery thereof. Each modular rib assembly includes a rib member for supporting a metalized mesh reflector surface attached thereto, a channel section base member, and a hinge assembly for pivotally connecting the rib members to their respective channel section base members. The channel section base members, in turn, are attachable between the top and bottom plate members of the hub assembly and also form a portion of the peripheral wall of the hub assembly.

Abstract: The illuminated animal collar includes a plurality of illuminating means along the surface of the collar. A switch is included, along with rechargeable power means. A plurality of solar cells are included to periodically recharge the rechargeable power means.

Abstract: A radio-frequency reflective surface is made of a fabric woven from a yarn having an effective coefficient of thermal expansion of substantially zero over a useful temperature range. The yarn comprises a metallic filament around which non-metallic rovings are wound. The coefficients of thermal expansion of the filament and the roving material are related to each other so that mechanical strain thermally induced in the filament by changes in temperature is counteracted by mechanical strain theremally induced in the rovings. Intermodulation products at yarn intersections of the fabric are substantially zero.
