Abstract: A wide-angle hinge assembly includes a frame hinge section and a door leafinge section connected to one another by a linkage arrangement. The linkage arrangement includes two double-armed link members and an intermediate link. The double-armed link members are pivotable about a common pivot point, and one of the link members pivotally engages one end of the intermediate link having its other end pivotally connected to the leaf hinge section. The linkage arrangement further includes a spring mechanism that is effective to provide a closing pressure during closing and maintaining the closed position for securing the door leaf. The spring mechanism is arranged on the intermediate link and coacts with a cam component included as a part of the leaf hinge section.

Abstract: A light box particularly adapted to back-light posters which includes a housing having a back wall, a peripheral wall and an opening opposite the back wall; a diffuser panel spanning the opening, an elongated lamp within the housing adjacent the peripheral wall for emitting radiation from the lamp peripherally inward toward the back wall and the diffuser panel, and first and second reflector surfaces respectively adjacent and more remote from the lamp with the first reflector surface having reflecting capabilities which are less then the reflecting capabilities of the second reflector surface. The lamp has material contiguous thereto for preventing emitted radiation directed from the lamp directly toward the diffuser panel from impinging upon the diffuser panel whereby bright spots on the back-lit poster are eliminated and the poster is back-lit uniformly over its area.

Abstract translation: 一种特别适用于背光海报的灯箱，包括具有后壁，周壁和与后壁相对的开口的壳体; 跨越开口的扩散器板，邻近外围壁的外壳内的细长灯，用于从外周向内朝向后壁和扩散板发射辐射;以及第一和第二反射器表面，分别与灯相邻并且远离灯， 第一反射器表面具有小于第二反射器表面的反射能力的反射能力。 该灯具有与其相邻的材料，用于防止从灯泡发射的辐射直接朝向扩散器面板撞击在扩散器面板上，从而消除了背光式海报上的亮点，并且该海报在其区域上均匀地背光。
