Patent number: 6830935Abstract: a method for separating particulate matter from a fluid, using apparatus which includes a container and cover, a filter assembly positioned in a housing atop the cover and suitable for collecting particulate matter in the fluid on a collection surface, and a dispersing element fixed relative to the cover. The cover has a portion that is fixed in a first position and freely rotatable in a second position. The specimen is placed in the container, and a mixer apparatus rotates the container in relation to the cover to disperse the particulate matter throughout the fluid. Upon deactivation of the mixer apparatus, a fluid sample including dispersed particulate matter is drawn through the filter assembly to capture a substantially uniform layer of particulate matter on the collection surface. The housing is then opened to expose the layer of particulate matter, which is then transferred to a microscope slide.Type: GrantFiled: June 25, 2001Date of Patent: December 14, 2004Assignee: LaMina, Inc.Inventors: Marianna El-Amin, Raouf A. Guirguis, Nashed Samaan

Publication number: 20040240314Abstract: An insert for a container includes an outer wall, a upstanding spout, and a bottom wall. The outer wall is configured to fit within an opening of the container and defines the periphery of the insert. The outer wall has a lower edge and an upper edge that is disposed at a first elevation. The upstanding spout is located within the outer wall and includes at least one substantially straight portion. The straight portion has a lower edge as well as a substantially straight upper edge that is disposed at a second elevation less than the first elevation. The bottom wall connects the lower edge of the outer wall and the lower edge of the spout to form a channel between the outer wall and the spout.Type: ApplicationFiled: May 29, 2003Publication date: December 2, 2004Applicant: Masterchem Industries, Inc.Inventors: Adam Armendariz, David Armendariz, John A. Heiser, Christopher E. Jones
