Abstract: A golf club face and protective shield for adhesion to the face of a golf club is provided such that a renewed surface for proper backspin is obtained. Adhesive holds the shield to the face of the golf club, and the striking surface is generally flat with a plurality of materials to mimic the surface of the face of a new golf club.

Abstract: An enclosed terrestrial antenna system of monocoque construction for receiving television signals from satellites in geostationary orbit. The basic antenna comprises two dish-shaped members having substantially identical configurations, each of which is a surface of revolution. Each member (called a "dish" in the industry) has a central concave parabolic area surrounded by an upstanding frusto-conic rim. One, the antenna dish, has an electromagnetic radiation reflecting surface on the concave side. The other, the cover dish, is substantially transparent to electromagnetic radiation. The cover dish has an opening at the center, along the axis of revolution. The two dishes are secured together, concave face to concave face. A feed mount is secured to the cover dish over the opening and carries the feed assembly in a manner allowing the feed assembly to be moved toward and away from the reflective surface to focus the feed.

Abstract: A reflector construction is disclosed. A semi-rigid reflector having a curved configuration includes a front reflecting surface and an opposite back surface. A semi-rigid backing has a peripheral margin substantially co-extensive with the periphery of the reflector. The peripheral margin of the backing projects forwardly with respect to the remainder of the backing. The remainder of the backing has a curved configuration generally approximating the curved configuration of the reflector. The peripheral margin of the backing is attaching to the periphery of the back surface of the reflector. The remainder of the backing is thus spaced from the reflector, and the reflector and the backing in combination provide a substantially rigid structure.

Abstract: The present invention provides an improved projection screen. The screen includes a film which is constructed of at least partially deformable, resilient material. One surface of the film has in combination a random matte texture and a substantially unidirectional striated texture. A layer of reflective material is deposited on the above-mentioned surface of the film to provide a high gain, damage resistant reflective surface. In one embodiment of the present invention, the layer of reflective material is located on the back surface of the film, and the front surface has a matte texture so that light from a projector or other source passes through the matte surface of the film to be reflected by the layer of reflective material on the back surface thereof. In another embodiment of the present invention, the layer of reflective material is located on the front surface of the film so that light projected on the screen is reflected by the layer of reflective material without passing through the film.
