Abstract: A solar reflector has a base support (5) made from injected thermoplastic material 1-7 mm thick. The base support (5) has a surface on a front face having a “mirror polish” surface finish and a geometry defined by an optical function. A structure of reinforcing ribs (13) in a rear portion to provide dimensional stability and assure the geometry defined by the optical function of the surface on the front face. Fixing bushings (6) are overmolded and integrated in the base support (5) having threaded holes (7) to receive threaded bolts and allow assembly regulation by the fixing bushings (6), the threaded bolts and lock nuts. The solar reflector also has a covering of a reflective metal (11) on the front face and a layer of protective fluids (12) on the covering of the reflective metal (11).

Abstract: In a control device of the "joystick" type in which movement of a single control lever is resolved into two orthogonal components, each component is represented by movement of one of a pair of pivoting members. Each such pivoting member has a respective coupling member mounted thereon for angular movement relative thereto about an axis perpendicular to the axis of the corresponding pivoting member. The two coupling members are connected to the control member so as to be restrained against relative translational movement.
