    摘要: Polymerization processes and polymers formed therefrom are described herein. Such processes generally include providing a catalyst system, introducing the catalyst system to a reaction zone, introducing 1-chlorobutane to the reaction zone, introducing an olefin monomer to the reaction zone, contacting the olefin monomer with the catalyst system in the presence of the 1-chlorobutane to form a polyolefin and withdrawing the polyolefin from the reaction zone. The catalyst system is generally formed from a process including contacting a magnesium dialkoxide compound with a first agent to form a first compound, contacting the first compound with a plurality of halogenating/titanating agents to form a reaction product and contacting the reaction product with an activating agent to form the catalyst system.

    摘要: A putter-type golf club head is provided having enhanced moment of inertia and alignment characteristics. The putter head includes a front body and a weight body. The weight body includes a central weight section extending rearwardly from the front body a prescribed distance to a rear weight section. The putter head is configured such that the rear weight section has a width less than the width of the front body and greater than a width of the central weight section. Thus, both the longitudinal and lateral moments of inertia are improved to offer greater forgiveness and increased accuracy during putts. The central weight section may include at least one and more preferably two elongated, high-density elements that are visible on a top surface of the sole between the front body and the rear weight section. The visibility of the elongated elements, with optional parallel markings on a top surface of the golf club head, also act as alignment aids to the golfer.

    摘要: Compositions including pellets of alum, a smectite mineral material, and optionally sodium or calcium carbonate, that can be delivered to a phosphate impoundment located at or near the bottom of a body of water. The pellets of alum, smectite mineral material and optionally sodium or calcium carbonate are dropped in a body of water, and the alum is released over time, as the pellet descends to the bottom of the body of water.

    摘要: A refrigerator includes a vertically extending airflow distribution assembly for reducing vertical temperature gradients therein, and laterally extending air passages are in flow communication with the air distribution assembly for reducing horizontal temperature gradients therein. A single fan simultaneously directs freezer compartment air into the air distribution assembly, the laterally extending passages and into a storage drawer for temperature regulation therein. A damper is located in flow communication with a light assembly and is selectively positionable to cool the refrigeration compartment through the air distribution assembly and the laterally extending passages, as well as to remove heat from the light assembly that may damage a refrigeration compartment liner.
