    • An injection mold for making a polygonal plastic article having a closed bottom and an open top is disclosed. A first mold section corresponds to the exterior dimensions of the bottom wall and a portion of the contiguous side walls of the article while a second mold section composed of plural elements defines the interior surface of the article. Plural side wall elements are movable relative to both of the mold sections from an open position spaced from both sections to a closed position wherein the side wall members interlock with both mold sections to form the mold enclosure. Linkage elements interconnect various of the mold elements to provide a coordinated movement. Other features are disclosed.

    • A reflex reflector which when vertically oriented spatially is adapted to continuously retro-reflect incident light rays horizontally striking such anywhere within an included angle of about 360*. Such reflector uses four reflective surfaces, arranged into two pairs of two surfaces each, the surfaces of each pair being in opposed, parallel relationship to each other, the pairs being oriented at 90* relative to each other. Each surface has reflex reflector facets adapted to retro-reflect over an angle of + OR - 45*.
    • 当空间垂直定向时,反射反射器适于连续反射入射光线,水平地照射到大约360度的夹角内的任何地方。 这种反射器使用四个反射表面,每个反射表面被布置成两对两个表面,每对两个表面中的每一对表面彼此相对并联,这些对相对于彼此成90度取向。 每个表面具有反射反射面,适合于+/- 45°的角度反射。

    • A process for electrostatically applying a multilayered coating on a substrate in one operation or step is disclosed, wherein a mixture of powders of at least two different coating materials is used as the coating composition, each powder, in the case of nonconducting powders, differing from the others in dielectric constant by a factor of at least 0.1, and the powders being of substantially different specific gravities, with the components having the lowest dielectric constant value having the lowest specific gravity value. At least one of the powders will be a powder of a film-forming non-conductive organic or inorganic polymer. Upon electrostatically applying a coating of this powdered composition to a conductive substrate which has a neutral charge or a charge opposite from that of the coating composition powder particles, the powders stratify into distinct layers of different compositions. The powders adhere to the substrate because of contact or static electrification for a reasonable length of time and until at least one of the powders can be cured or fused to form the final coating. Thus, for instance, in only one pass with an electrostatic spray gun, a protective coating of superimposed layers of zinc, epoxy, and polyethylene can be applied to a conductive substrate.

    • A double-acting proportioning pump having a receiving chamber and a mixing chamber for accurately mixing and delivering two fluids such as a liquid and air in a system. The double-acting pump includes a single stationary piston and reciprocating cylinder whereby the fluids are conveyed and mixed by the alternate expansion and contraction of each pump chamber, with one of the fluids passing from the receiving chamber to the mixing chamber through the single piston element. The pump is cylindrical with end cap members at each end thereof; the piston is disposed between the end caps and the two pump chambers are each defined by an end cap member and one radial end face of the piston. Cyclical valve means alternately open and close the passage through which one of the fluids communicates with the receiving chamber. Adjustable air inlet means vary the quantity of air admitted to the mixing chamber, thereby varying the ratio of mixed ingredients in the final product.
