Patent number: 7261939Abstract: A tablet comprising a core which is at least partially coated with an outer layer obtained by electrostatic deposition of a powder and subsequent fusing of the deposited powder to form a film characterised in that a surface of the tablet coated with said outer layer is contoured to provide higher regions and lower regions, the outer layer having a different colour in said lower regions to the outer layer in said higher regions.Type: GrantFiled: May 2, 2002Date of Patent: August 28, 2007Assignee: Phoqus LimitedInventors: Martin D. Hallett, Linda A. Reeves, Marshall Whiteman

Patent number: 6806017Abstract: In a method of electrostatically applying a powder material to a solid dosage form, charged powder material is applied to a photoconductive drum (3), is transferred to an intermediate belt (4) and then to a solid dosage form (5). The belt (4) makes contact with the solid dosage form (5).Type: GrantFiled: December 19, 2002Date of Patent: October 19, 2004Assignee: Phoqus LimitedInventors: Linda Ann Reeves, David Hoover Feather, Douglas Howard Nelson, Marshall Whiteman

Publication number: 20040177809Abstract: The invention provides apparatus for electrostatically coating a pharmaceutical tablet core with powdered coating material. The apparatus comprises a first rotary drum (12) on which a core is held in electrical isolation from its surroundings but at a potential difference to earth by an electrode which contacts the core. The core is carried past a coating station B at which particles of powder having an opposite potential difference to earth are held in a tray (18). The surface of the drum is held at the same potential difference to earth as the powder particles. The powder is attracted to the core, and not to the drum, coating the exposed surface of the core. The drum carries the coated core past a fusing station C at which a heater fuses the powder to form a continuous film coating. The core is then turned and transferred onto a second drum (12′) where the other surface is coated in the same way.Type: ApplicationFiled: December 19, 2003Publication date: September 16, 2004Applicant: Phoqus LimitedInventors: John E. Hogan, John N. Stannforth, Linda Reeves, Trevor Page

Publication number: 20030138487Abstract: An apparatus and method for locking a gun. The apparatus includes a dummy round configured for insertion into a firing chamber of a gun, a locking component configured for coupling with the dummy round, and an elongated sleeve rotatably coupled with the locking component. The locking component includes a keyed head positioned within a longitudinal channel of the elongated sleeve. The locking component and elongated sleeve are insertable through the discharge end of a gun's barrel. An actuating mechanism, such as a key is insertable through the channel of the elongated sleeve to engage with the keyed head and rotate the locking mechanism relative to the elongated sleeve. Rotation of the locking mechanism effects a friction lock between the locking mechanism and the dummy round.Type: ApplicationFiled: November 19, 2001Publication date: July 24, 2003Applicant: Phoqus LimitedInventors: John E. Hogan, Trevor Page, Linda Reeves, John N. Staniforth

Publication number: 20020197388Abstract: A method of coating a pharmaceutical substrate includes the steps of applying an active coating material to a surface of the substrate to form an active coating layer and applying a cover coating material onto the active coating layer to form a cover coating layer. The active coating layer is substantially completely covered by the cover coating layer.Type: ApplicationFiled: September 26, 2001Publication date: December 26, 2002Applicant: Phoqus Limited.Inventors: Steven R. Brown, Linda A. Reeves, John N. Staniforth

Patent number: 6117479Abstract: Method of electrostatically coating a substrate wherein the substrate is brought to a coating station at which it is held substantially electrically isolated from its surroundings adjacent a source of particulate coating material. The substrate and the coating material are held at a potential difference to each other sufficient to coat the exposed surface of the substrate with particles of coating material.Type: GrantFiled: November 10, 1997Date of Patent: September 12, 2000Assignee: Phoqus LimitedInventors: John E.
