Publication number: 20130344259Abstract: An alcohol-free aqueous pearl treatment composition that includes a water-based emulsion of particle size less than 1.0 microns, wherein, in use, the alcohol-free aqueous pearl treatment composition infuses into pearls to inhibit ageing of the pearls. This disclosure describes a method for the treatment of pearls including the steps of: a) introducing into a bath an alcohol-free aqueous composition, the composition comprising a water-based emulsion of particle size less than 1.0 microns; b) introducing one or more pearls into the bath; and c) operating the bath for a prescribed period to allow the alcohol-free aqueous composition to infuse into the one or more pearls in a first treatment step; wherein, in use, the alcohol-free aqueous composition inhibits ageing of the one or more pearls.Type: ApplicationFiled: June 24, 2013Publication date: December 26, 2013Inventors: Stephen Paul Birkbeck, Christian Sarbach

Patent number: 8343158Abstract: A tool (2) for forming a cavity within a bone (6) comprises a shaft (10) and a blade (12) which is pivotally mounted on the shaft towards one end thereof. A rod is fastened to the blade, and can slide within the shaft, to change the pivotal position of the blade relative to the shaft. The tool can include an incremental drive to cause the rod to translate along the shaft when the shaft and rod are rotated.Type: GrantFiled: February 14, 2008Date of Patent: January 1, 2013Assignee: Depuy International LimitedInventor: Alec Paul Birkbeck

Patent number: 8206405Abstract: A computer aided surgery system, method, surgical method and instrument for guiding the positioning of an acetabular cup in a pelvis are described. The position of the transverse acetabular ligament of the pelvis and the position of the acetabular labrum of the pelvis are determined. The orientation of an acetabular plane including the acetabular labrum and the transverse acetabular ligament is calculated. A planned position for the acetabular cup is determined, in which an inlet plane of the cup is substantially parallel to the acetabular plane. The instrument comprises a mounting for attaching the instrument to a patient, a support, a guide defining a longitudinal axis, and for receiving a further instrument bearing the acetabular cup implant, and an adjustment mechanism. The adjustment mechanism can allow the angular orientation of the guide to be adjusted about at least two different axes to allow the inclination and version or anteversion of the longitudinal axis to be altered.Type: GrantFiled: October 9, 2007Date of Patent: June 26, 2012Assignee: Depuy International LimitedInventors: David Beverland, Alec Paul Birkbeck, Frank Foley, Ian Revie, Mike Slomczykowski

Patent number: 7452456Abstract: A water sanitization apparatus is provided. The apparatus includes a power unit, a housing with inlet and outlet openings for permitting the passage of water containing a bromide salt into the housing and water containing a free bromine and a sanitizing metal ion out of the housing, respectively, and first and second electrodes electrically connected to the power unit. The first electrode has a graphite or carbon substrate doped with copper, silver, and/or zinc. When operated as an anode, the first electrode converts bromide salt to free bromine and oxidize doped metal to sanitizing metal ion. Also provided are related water treatment systems and methods.Type: GrantFiled: December 1, 2004Date of Patent: November 18, 2008Assignee: Pioneer H2O Technologies, Inc.Inventor: Paul Birkbeck

Publication number: 20080228188Abstract: A surgical guide and computer aided surgery method of use thereof are described. The guide is mounted on a body part to guide a device along a guide axis. The body has a channel in it which defines the guide axis and which receives the device in use. A base engages the surface of the body part when mounted on it in use, and supports the body over an entry point for the body part with the guide axis passing through the entry point. A pivot mechanism attaches the body to the base. The body can move relative to the base by pivoting only. The guide is configured such that the entry point is a centre of motion about which the body pivots.Type: ApplicationFiled: September 21, 2007Publication date: September 18, 2008Inventors: Alec Paul Birkbeck, Gary Moore

Patent number: 7351331Abstract: A bromine generator apparatus is provided for producing bromine from a bromide salt. The apparatus includes an electrical power unit, a housing, and first and second electrodes. The housing has inlet and outlet openings constructed and arranged for permitting the passage of water containing a bromide salt into the housing and water containing bromine out of the housing, respectively. The first and second electrodes electrically are connectable to the electrical power unit and have first and second contact regions, respectively, in the housing for contacting water passing through the housing and converting the bromine salt to the corresponding free bromine. The first and/or second contact regions are made of non-woven extruded graphite.Type: GrantFiled: September 8, 2004Date of Patent: April 1, 2008Assignee: Pioneer H20 Technologies, Inc.Inventor: Paul Birkbeck

Patent number: 6656178Abstract: A vertebral-column device that is suitable to be received in an intervertebral space between two dorsal vertebrae, the prosthesis comprising a curved strip of biocompatible material. The width of the strip being such that after placement, the strip makes contact with the vertebrae. The strip is manufactured from a material that can undergo great deformations before permanent deformation arises. The strip is curved in a shape in which the extremities are situated apart from one another and the radius of the curved parts and the thickness of the strip are chosen in such a way that when the strip is bent out into an approximately straight strip, scarcely any permanent deformation arises. Thus, the strip which has been bent out into an approximately straight strip is capable of being introduced into an intervertebral space where the strip assumes its original curved shape.Type: GrantFiled: July 27, 2000Date of Patent: December 2, 2003Assignees: Baat B.V.
