The result is the sensation of greater water flow than actually achieved by the shower head and increased rinsing of the body with decreased water flow.Type: GrantFiled: March 5, 1990Date of Patent: November 19, 1991Inventor: Timothy L.

Patent number: 5019259Abstract: A filter underdrain apparatus comprises plate means forming a plurality of horizontal distributor conduits, the conduits being in juxtaposed, laterally-spaced relationship and constructed and arranged to defined alternating conduits and troughs of a filter underdrain. At least some of the horizontal distributor conduits include interior partitions extending along such conduits and dividing the interior of each such conduit into a liquid passage and a gas passage. Liquid metering orifices communicate the interior of the liquid passage with the exterior of the distributor conduit for substantially evenly distributing backwash liquid flows from the liquid passage and for passing filtered liquid flows into the liquid passage. Gas metering orifices communicate the interior of the gas passage with the exterior of the distributor conduit for substantially evenly distributing gas from the gas passage when connected with a pressurized gas source.Type: GrantFiled: June 15, 1989Date of Patent: May 28, 1991Inventor: John B. Hambley

Patent number: 4969602Abstract: An apparatus for dispensing adhesive in an elongated strand or fiber in a controlled, spiral pattern upon a substrate comprises a dispensing device having a nozzle formed with an adhesive delivery passageway and an air delivery passageway both of which terminate at the base of the nozzle. A nozzle attachment in the form of an annular plate is mounted to the base of the nozzle by a cap. The annular plate is formed with a throughbore which receives hot melt adhesive from the adhesive delivery passageway and ejects an adhesive bead through a nozzle tip formed on the outer side of the plate opposite the nozzle. An annular groove formed in the outer side of the plate facilitates drilling of air jet bores therein at an angle relative to the throughbore and adhesive bead ejected therefrom.Type: GrantFiled: September 29, 1989Date of Patent: November 13, 1990Assignee: Nordson CorporationInventor: Charles H. Scholl

Patent number: 4896796Abstract: A hand operable dispensing package for dispensing first and second viscous products in a composite product having a bead of the first viscous product and a plurality of spaced apart longitudinally extending stripes of the second viscous product on the outside of the bead of the first viscous product. The dispensing package has a polygonal elongate dispensing spout with a generally star-shaped tip to dispense the first viscous product in a star-shaped configuration with a core portion and a plurality of lobes extending outwardly from the core portion, and a circular annular insert snugly positioned in the dispensing spout with an outer surface of an inner portion of the annular insert and an inner surface of an inner portion of the dispensing spout defining an annular recess and a circumferential series of longitudinally extending passages.Type: GrantFiled: November 18, 1988Date of Patent: January 30, 1990Assignee: Owens-Illinois Closure Inc.Inventor: Kurt N. Harris

Patent number: RE33481Abstract: An apparatus for spraying heated hot melt adhesive in elongated strands or fibers in a controlled, spiral pattern upon a substrate comprises a spray gun having a nozzle formed with an adhesive delivery passageway and an air delivery passageway both of which terminate at the base of the nozzle. A nozzle attachment in the form of an annular plate is mounted to the base of the nozzle by an end cap. The annular plate is formed with a throughbore which receives hot melt adhesive from the adhesive delivery passageway and ejects an adhesive bead through a nozzle tip formed on the plate. An annular groove formed in the plate facilitates the drilling of air jet bores therein at an angle relative to the throughbore and adhesive bead ejected therefrom.Type: GrantFiled: April 28, 1989Date of Patent: December 11, 1990Assignee: Nordson CorporationInventors: Roger A. Ziecker, Bentley J. Boger, Dwayne N. Lewis
