Patent number: 8802362Abstract: Methods and devices for preparing a solid-fibrin web are provided. One method may include drawing blood from a patient, separating plasma from the blood, contacting the plasma with a calcium-coagulation activator and concurrently coagulating and axially centrifuging the plasma to form the solid-fibrin web. The solid-fibrin web may be suitable for regenerating body tissue in a living organism. Devices used in the methods may also be provided.Type: GrantFiled: May 18, 2010Date of Patent: August 12, 2014Assignee: Cascade Medical Enterprises, LLCInventors: Nicholas A. Grippi, Roberto C. Beretta

Patent number: 8377301Abstract: An apparatus and method for separating solids from a fluid. The apparatus includes a first container for receiving solids and fluid and a second container adjacently disposed to the first container in fluid communication therewith. The apparatus includes a conveying member extending upwardly from the bottom of the first container and angling upwardly through the second container such that the conveying member transports solids that settle to the sloped bottom portion of the first container from the first container and through the second container. A conveyor member housing may be disposed in the second container so as to provide an enclosure about the conveyor member to prevent solids that are being transported through the second container by the conveyor member from being deposited into the second container while permitting fluid that separates from the solids during transport to pass from the conveyor member housing and into the second container.Type: GrantFiled: December 15, 2008Date of Patent: February 19, 2013Assignee: 4 M Welding, Inc.Inventor: Thomas D. Miller

Patent number: 4043920Abstract: In a continuously operating square settling tank, the provision of scum skimming devices wherein a pivotally mounted corner exploring skimmer member is swingable in a predetermined horizontal plane, while kept in contact with the peripheral scum baffle during rotation of the supporting rake structure. This skimmer member forms with the scum baffle a scum collecting pocket whereby when the thus collected scum is pushed up along the slope of a ramp, it is trapped and thereby contained on the ramp for delivery into a receiving box connected to the ramp.The scum collecting effectiveness of the skimmer member may be enhanced by the additional provision of a directional skimmer blade cooperatively so related to the swingable skimmer member, that floating scum material is thereby guided into said collecting pocket.Type: GrantFiled: August 25, 1976Date of Patent: August 23, 1977Assignee: Dorr-Oliver IncorporatedInventor: Thomas Wooh
