Abstract: Embodiments are directed towards a use of a supported biphenylphenol polymerization catalyst to make a polymer via a slurry-phase polymerization process, where the supported biphenylphenol polymerization catalyst is made from a biphenylphenol polymerization precatalyst of Formula I.

Abstract: A machine that vends a predetermined number of golf balls when activated by a coin or token-operated slide mechanism. A large plurality of golf balls are placed in a hopper and the balls are fed from the hopper, one at a time, into an elongate pipe that discharges into a bucket positioned in a chamber near the bottom of the machine. A motor rotates a turntable having golf ball receiving apertures formed in its outer periphery so that the balls fill each aperture as the turntable rotates. The upper end of the pipe is in the path of travel of and is in open communication with apertures formed in the turntable so that rotation of the turntable continuously fills the pipe as the apertures pass over its open end. Numerous structural features, including vibrating members, insure that the balls will not jam in the hopper and additional design features insure a jostling of the balls in the vicinity of the pipe's upper end to insure against jamming at that critical location.
