Abstract: The entraining element is constructed of a carrier, a striking member and a support member. The striking member is fixed to the conveyor chain via the carrier and has a resilient striking plate which extends transversely of the gripper shuttle path for returning a shuttle to the picker. The support member is mounted behind the striking plate to define a gap with the striking plate in the unloaded state. Upon deflection of the striking plate during loading, the plate abuts resiliently against the support member.

Abstract: A pill box has a sliding cover for a bottom part having a rim on which an elastically compressible gasket is positioned, providing moisture-proofness. By a programmed squeezing together and sliding action the cover may be slid from the bottom part to gain access to the box's interior, the programmed actions making the box child-resistant. The gasket functions both as a seal and as a spring which keeps the cover and bottom part biased apart.

Abstract: A positive active material for electric primary cells, such as are used in electronic watches, is formed from a powder composed at least partially of grains having cores of silver peroxide completely surrounded by a layer of monovalent silver oxide and covered with a thin surface layer of metallic silver. The remainder of the powder, if any, comprises monovalent silver oxide grains, also covered with a thin surface layer of metallic silver. A process for making the material includes adding a reducing agent such as hydrazine to a powder having grains of less than 50 microns in diameter of essentially pure silver peroxide and reducing the silver peroxide to the point at which a thin layer of metallic silver forms on the surface of each powder grain. This point can be detected by a substantial reduction in electrical resistivity of the powder and occurs when approximately one-half of the original powder remains as silver peroxide.
