Abstract: A household appliance for performing a cycle of operation according to a cycle of operation. The household appliance includes a cabinet defining a treating chamber, a tub located within the cabinet interior and defining a tub interior and having an access opening, a rotatable drum located within the tub interior, a user interface carried by the cabinet and coupled to a controller to provide data communication between the controller and a user, a pedestal for supporting the cabinet and comprising a liquid recirculation system for recirculating liquid to the treating chamber, at least one consumable received in a dock positioned in the pedestal for use in performing the cycle of operation, and, a luminary communication interface physically separated from the user interface and configured to emit at least one of colored light motion or light intensity patterns to illustrate a status of the at least one consumable.

Abstract: A curb box for underground gas and water services formed of a synthetic plastic material wherein the lower portion of the curb box is formed with a bell housing for receiving a service or distribution line valve. The bell housing includes valve engaging surfaces frictionally contacting the valve wherein such frictional engagement initially positions the valve upon the curb box and resists inadvertent displacement between the valve and curb box during installation, back filling and settling.

Abstract: Olefin polymerization catalysts prepared by reducing transition metal compounds with an organometallic compound are rendered highly efficient by reacting excess organometallic compound with a deactivation agent, such as hydrogen chloride, prior to activation of the catalyst with organoaluminum compounds. Catalyst efficiencies of as high as 700,000 grams of polyethylene per gram of transition metal in the catalyst have been attained at reactor pressures of only 50 psig.

Abstract: A unique high efficiency catalyst has been developed for the polymerization of ethylene. The activity of the catalyst, which uses a mixed magnesium-aluminum alkyl as a reducing agent for tetrabutyltitanate, and hydrogen chloride to deactivate excess reducing agent, is dependent on a specific and unpredicted order of addition of catalyst components.
