Patent number: 6488427Abstract: An applicator for dispensing a product comprises an exterior top surface, an exterior sidewall, and a base. The applicator has a chamber which constitutes a reservoir for holding the product to be dispensed. The reservoir has top wall, a bottom wall and a side wall. The applicator has an orifice for dispensing product, and the orifice connects the top surface to the top wall. The chamber has a disk capable of traveling through the chamber forcing product through the orifice as it travels through the chamber. The disk has a product contact surface that contacts a major portion of the top surface when the travel of the disk is complete so that product remaining in the chamber is minimized.Type: GrantFiled: February 29, 2000Date of Patent: December 3, 2002Inventors: Diane C. Breidenbach, Laurence W. Mille

Patent number: 6287969Abstract: Disclosed herein is a method of forming a superconductor, comprising the steps of: providing a substrate and exposing the substrate to a first atmosphere, including precursors to form a first epitaxial layer segment. The first layer segment is then exposed to a second atmosphere, including precursors to form a second epitaxial layer segment, and the second layer segment is exposed to a third atmosphere including precursors to form a third epitaxial layer segment. Each of the first and third layer segments are each formed from a superconductor material and the second layer segment is formed from a material different from the first and third layer segments and the first, second and third layer segments have a collective thickness, the third layer segment having an outer surface with a roughness which is less than that of a single layer of the superconductor material with a thickness equal to the collective thickness.Type: GrantFiled: May 6, 1999Date of Patent: September 11, 2001Assignee: McMaster UniversityInventors: Robert A. Hughes, Patrick J. Turner, John S Preston

Patent number: 6232694Abstract: This invention relates to improvements in electric power systems for aircraft and, more particularly, to such systems which provide both starter and generator functions. The present invention has particular applicability to starter generators for helicopters having a body with an end bell, a commutator head assembly and a fan cover assembly, and wherein the starter generator does not have an end bell that permits air to exhaust through said end bell. The starter generator of the present invention has a commutator head assembly having a frame with a top end and a base end, the top end being adapted to fit within the fan cover assembly and be retained therein by a suitable means, the commutator head assembly having with a plurality of slots that are designed to exhaust air flow passing over one or more brushes in the starter generator.Type: GrantFiled: July 1, 1999Date of Patent: May 15, 2001Inventor: John Leslie
