Patent number: 8088313Abstract: A measured amount of a material that is crosslinkable by impingement of a suitable form of energy, especially UV light, is introduced into a two-part mould of which the cavity determines the shape of a moulding to be produced. The two mould halves are held a small distance from one another so that a thin annular gap is formed between them, which gap is in communication with the mould cavity and through which gap excess material can escape. The crosslinking is triggered by impingement of the selected form of energy, the impingement being spatially restricted to the cavity by suitable masking so that material disposed outside the mould cavity is not crosslinked. In that manner mouldings are obtained that do not require subsequent mechanical processing, and the mould is reusable. The process is especially, but not, however, exclusively, suitable for the manufacture of contact lenses.Type: GrantFiled: June 9, 2004Date of Patent: January 3, 2012Assignee: Novartis AGInventors: Peter Hagmann, Sharla Borghorst, John Golby, Peter Herbrechtsmeier, Otto Kretzschmar, Bernhard Seiferling, Norbert Söllner, Beat Müller

Patent number: 6342570Abstract: The present invention describes novel statistical copolymers and the preparation and possible uses thereof. Copolymers are described that are water-soluble and cross-linkable and that comprise the copolymerization product of a monomer mixture consisting substantially of a vinyl lactam (a) and at least one further vinyl monomer (b) of a different type selected from the group consisting of hydrophobic, hydrophilic and functional vinyl monomers, wherein the monomers are present in the copolymer in the form of statistically distributed building blocks, and, if a functional vinyl monomer is present as a building block in the copolymer, that building block is, where appropriate, modified with a reactive vinyl monomer (c), the reactive vinyl monomer (c) being linked to a building block of a functional vinyl monomer with retention of its vinylic group and with the formation of a covalent bond.Type: GrantFiled: March 26, 1999Date of Patent: January 29, 2002Assignee: Novartis AGInventors: Harald Bothe, Achim Müller, Bernhard Seiferling, Sharla Borghorst, John Golby, Peter Hagmann, Peter Herbrechtsmeier, Otto Kretzschmar

Patent number: 6113817Abstract: Efficient and consistent processes for manufacturing moldings, especially ophthalmic lenses such as contact lenses. The processes comprises a series of improvements, including improvements in the areas of conditions for dispensing liquid prepolymer into lens molds, male and female mold mating, reusable molds, mold cleaning, lens separation from molds (demolding), lens handling, and in-line inspection. Cyclic series of processing steps are also disclosed. Additionally, an improved molding tool is disclosed, with the molding tool including a male mold housing and a female mold housing, each of which have disposed therein a plurality of mold halves.Type: GrantFiled: March 24, 1998Date of Patent: September 5, 2000Assignee: Novartis AGInventors: Peter Herbrechtsmeier, Karl Baur, Roger Biel, John Golby, Roland Hauck, Peter Hagmann, Axel Heinrich, Otto Kretzschmar, Anette Lang, Achim Muller, Thomas Schulz, Bernhard Seiferling, Werner Steffan

Patent number: 5782460Abstract: In a process for the manufacture of mouldings, especially optical lenses, specifically contact lenses (CL), a starting material that is crosslinkable by the impingement of suitable energy is introduced into a mould (1) having a cavity (15), which mould is at least partially permeable to the energy concerned. The starting material is introduced into the cavity in a still at least partially uncrosslinked state, the mould cavity determining the shape of the moulding (CL) to be produced. By means of impingement of the energy concerned, the starting material is crosslinked to an extent sufficient for it to be possible for the moulding (CL) to be released from the mould. The filling of the mould cavity is carried out in the starting material that is still at least partially in the uncrosslinked state.Type: GrantFiled: August 13, 1996Date of Patent: July 21, 1998Assignee: CIBA Vision CorporationInventors: Otto Kretzschmar, Sharla Borghorst, John Golby, Peter Hagmann, Peter Herbrechtsmeier, Bernhard Seiferling, Beat Muller

Patent number: 5609246Abstract: The blister pack comprises a base portion and a cover layer. The base portion comprises a hollow chamber that contains a soft hydrophilic contact lens and a sterile aqueous preserving solution, and a substantially flat flange that extends right round the outside of the hollow chamber. The cover layer is releasably sealed to the flange in a sealing zone that extends right round the circumference of the hollow chamber. The flange comprises a grip region that extends from one side of the hollow chamber beyond the sealing zone and is covered by a corresponding grip region of the cover layer but is not sealed thereto.Type: GrantFiled: May 3, 1995Date of Patent: March 11, 1997Assignee: Ciba Geigy CorporationInventors: Sharla Borghorst, Erich Baumann, John Golby, Peter Hagmann, Peter Herbrechtsmeier, Otto Kretzschmar, Bernhard Seiferling, Michele De Lucchi, Torsten Fritze, Masahiko Cubo

Patent number: 5469259Abstract: An inteferometer is provided with a light source forming a first collimated beam shaped to illuminate an area and a second collimated beam shaped to illuminate a narrow line. Both of these beams are split into orthogonally-polarized sub-beams, which are diverted outward and inward within a compound Wollastom prism. The images of these beams are focussed on a test surface through an objective lens, with a real splitting point being projected to the rear focal plane of the objective lens. With light reflected off the test surface and projected back through the compound Wollastom prism, interference patterns are generated on the surface of a line sensor, which is typically used with illuminated narrow lines split by the compound prism and projected onto a moving test surface, and on the surface of an area sensor, which is typically used with area illumination projected onto a stationary test surface. Autofocus and automatic phase angle correction servomechanisms are also provided within the interferometer.Type: GrantFiled: January 3, 1994Date of Patent: November 21, 1995Assignee: International Business Machines CorporationInventors: John A. Golby, Miles J. Padgett, Stephen P. Woodall
