The hanger device has a composite structure including both metallic and polymeric components. The mounting bracket is formed of primarily metallic components to provide adequate hang strength, and a thin profile for use in so-called over-the-door hanger devices supported on the top edge of a door below the lintel or frame member when the door is in the closed position.

A system designs a thin and relatively flat microwave focusing lens that can produce multiple simultaneous beams, using readily-available isotropic dielectric materials, and having a gradient-index (GRIN) profile. The design optimizes the lens to achieve beam scanning and / or multiple beams over a wide field of regard (FOR) with broad bandwidth and a very short focal length compared with conventional lenses. The lens can be used individually or as an element in a more complex antenna having multiple lenses in various orientations that are independently switched, selected and / or excited simultaneously as elements in a phased array. The antenna terminal incorporates such lens into an array of lenses along with one or more feeds to produce single or multiple beams covering a broad field of regard for such applications as satellite communications on-the-move, cellular, broadband point-point or point-multipoint and other terrestrial or satellite communications systems. The lens and array design support multiple simultaneous independently steerable beams as well as null placement for interference cancellation.

A reverse angled threadform with anti-splay clearance includes inner and outer helical threads, each with respective leading stab flanks and trailing load flanks, the load flanks mutually engaging when an inner member with the inner threads is advanced into an outer member with the outer threads. The inner load flanks form acute angles with a helical axis, while the outer load flanks form obtuse angles with the helical axis. The clearance is formed between the stab flanks of the inner and outer threads. On threadforms with root and crest other than angular peaks, such as cylindrical root and crest surfaces, the anti-splay clearance is also formed between the mutually facing root and crest surfaces of the inner and outer threads. The load flanks may be parallel, outwardly diverging, or outwardly converging.

This invention generally relates to decorative spinners. More specifically, this invention relates to a spinner apparatus rotated about its vertical axis, either by wind blowing across its face or in a second embodiment, spun by a motor drive unit. The spinner apparatus consists of a number or set of letters or other decorative symbol or logo on or in a pad centered between concentric bands of tinted transparent material coated metal which are connected at the top and bottom and progressively radially displaced about their vertical axis as they approach the inner band. When the device is spun either by the wind blowing it or by an electric motor, the numbers, letters or symbols stand out and appear to be stationary in the line of sight of the viewer and the bands progressively rotated off the plane of the outside band and the center detail provide an interesting wind catching and light reflecting three dimensional shape. When the spinning apparatus is lighted at night it takes on an electric glow appearance and the light appears to move either from the center outward or from the outside inward depending on the direction of rotation.
