Abstract: The disclosed solid waste pump is a chopper pump, and preferably a chopper pump having a small rated motor and a semi-open impeller design. Particularly, a chopper pump having an impeller, at least one pump-out vane, an end plate, and a back plate including at least one cutting rib is disclosed. The impeller includes a back shroud and cutting vanes sharpened on a first edge extending opposite the back shroud and fixed on a first surface of the back shroud. The at least one pump-out vane is preferably fixed to a second surface of the back shroud opposite the first surface, while the end plate includes a surface adjacent to and facing the first edge of the cutting vanes and at least one internal cutting rib fixed to the end plate surface for shearing operation in combination with the sharpened edge of the cutting vanes of the impeller.

Abstract: A cutting assembly for positioning at the intake end of a centrifugal pump used for pumping liquids and slurries containing solid matter, including various types of refuse, and for chopping the solid matter which may thereafter be processed for disposal is disclosed. The cutting assembly includes an intake end plate having a body defining the opening to allow the passage of material, such as waste water and the like, therethrough. The intake end plate attaches at the intake end of the chopper pump. The assembly also includes at least one, and preferably a plurality of cutter bars projecting from the body of the intake end plate into the opening, and a nut positioned at the intake end and attached to the chopper pump within the opening of the intake end plate.

Abstract: Customizing products and services offered by an out-of-home vacation provider to a customer's personal preferences includes creating a customer profile. Data about a customer's preferences is collected. The collected data is stored in the customer profile, and using a decision tree customizes the customer's vacation experience based on the collected data.

Abstract: A multi-stage air scrubbing apparatus for removing particulate matter from contaminated air is located beneath the perforate floor of a chamber from which the contaminated air flows in order to allow light to enter the chamber and to permit visual observation of its interior. The apparatus includes a sub-floor flooded with a flowing scrubbing fluid and a scrubbing fluid spray source and conduit means having baffle members that cause the air and the fluid spray to flow in a direction-reversing serpentine path. The contaminated air passes through the scrubbing fluid spray at least twice, and preferably three or more times, in order to remove the particulate matter therefrom.

Abstract: The disclosure relates to a new apparatus for fluid dispersion for use in removing particulate matter from air. A spray head or other fluid spray-producing means comprises a rigid spray plate bent to a predetermined configuration with two spray head side plates attached to said spray plate, and two spray head side guide bars attached to said side plates. A pressurized fluid, such as water, is delivered at the bottom of the spray plate whereupon impact with the surfaces of the spray plate, side plates and guide bars causes the fluid to be dispersed in spray form. Through this spray is passed contaminated air containing undesirable particulate matter such as paint overspray, whereupon the air is scrubbed to remove substantially all of the particulate matter.

Such a spray head apparatus would typically be located at the base of a scrubbing unit connect to a paint spray booth or the like, said scrubber containing baffles through which contaminated air is passed and cleaned prior to emitting the remaining particle-free air to the atmosphere.
