Patent number: 6434826Abstract: A nozzle plate, particularly for fuel injection valves, with at least one flow path which has at least one supply opening, which path includes a ring gap which opens into a ring-shaped exit opening, as well as a method for the production of such a nozzle plate. For the nozzle plate, it is provided that the flow path has a ring channel assigned to the supply opening, which channel makes a transition into a cylinder-shaped ring gap with a cross-section which narrows in the region of the exit opening. The production of the nozzle plate takes place in that a cavity mold corresponding to the flow path through the nozzle plate is produced, that a layer embedding the cavity mold is galvanically deposited, and that the cavity mold is removed from the galvanically deposited layer.Type: GrantFiled: September 1, 1998Date of Patent: August 20, 2002Assignee: Robert Bosch GmbHInventor: Hans Kubach

Patent number: 6432247Abstract: A hearing aid instrument of the in-the-ear type (and preferably CIC) provides a plate member with electronic hearing aid components mounted thereto. The plate member is preferably of a harder material such as hard plastic. A soft polymeric body is bonded to the plate member and encapsulates preferably a plurality of the electronic hearing aid components. The body is soft and is shaped to conform to the ear canal of the user. The soft polymeric body and encapsulated electronic hearing aid components define a soft structure compliant to the ear canal during use and that is substantially solid and free of void spaces between at least some of the components and the ear canal. This combination of soft compliant structure and encapsulated electronic hearing aid components addresses problems of peripheral leakage, poor fit, pivotal displacement that occurs with jaw motion and internal cross talk of components housed in prior art hollow type hearing aids.Type: GrantFiled: October 28, 1998Date of Patent: August 13, 2002Assignee: Softear Technologies, L.L.C.Inventors: Roger P. Juneau, Lynn P. Creel, Edward J. Desporte, Michael Major, Gregory R. Siegle, Kelly M. Kinler

Patent number: 6427310Abstract: A print engine chassis for supporting an imaging drum (14) and a printhead translation assembly (40) is fabricated by joining the interlocking rigid members using tab (36) and slot (38) junctions to form a sheet metal frame (12) and then coating the sheet metal frame with a plastic (39) to bond the rigid members in place. Additionally, a the rigid members may be predipped in plastic prior to joining.Type: GrantFiled: February 15, 2000Date of Patent: August 6, 2002Assignee: Eastman Kodak CompanyInventor: Roger S. Kerr

Publication number: 20020056938Abstract: The uneven surfaces of wood-based materials such as chipboard may be improved by applying a formable coating material, smoothing and/or modelling the coating material to achieve a smoother surface, and heating the coating material to form closed pores while maintaining the smoothed surface intact. Decorative and flexible layers may also be applied to such surfaces in this manner.Type: ApplicationFiled: February 19, 1999Publication date: May 16, 2002Inventors: RAINER HASENKAMP, LOTHAR THIELE

Patent number: 6383429Abstract: A method and a piece of sculpture made with the method, begins by forming a first three-dimensional transparent member having a selected surface which is intended to become a visible embedded surface in the sculpture. Acrylic resin is preferred for the first member but other clear cast material can also be used. A film of water or alcohol soluble material, preferably PVA with or without additive and solvent, is sprayed onto the selected surface, preferably using an air brush. The film is allowed to dry and the first member with the film is placed in a mold having a cavity with a shape of the final sculpture product, the cavity having room for at least part of the first member, and a void corresponding to the shape of a second member. The selected surface is at least partly exposed to this void in the mold. The mold is then filled a transparent castable liquid material, which may also be acrylic resin, and the contents of the mold are cured to form the sculpture.Type: GrantFiled: October 27, 1999Date of Patent: May 7, 2002Inventor: Mario Noto

Publication number: 20020019181Abstract: A composite fabric for use in reinforcement, particularly tensile reinforcement, of cementitious boards and similar prefabricated building wall panels. The fabric is constructed as a mesh of continuously coated, high modulus of elasticity strands. The high modulus strands are preferably bundled glass fibers encapsulated by alkali and water resistant thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof. The fabric provides long-lasting, high strength tensile reinforcement of the panels or boards regardless of their spatial orientation during handling. The reinforcement also enhances the impact resistance of the boards after installation. Included as part of the invention are methods for making the reinforcement, cementitious boards and panels including the reinforcement, and methods for manufacturing such boards and panels.Type: ApplicationFiled: April 27, 2001Publication date: February 14, 2002Applicant: Bay Mills Ltd.Inventors: Ian Cooper, John F. Porter, Jeremy-Jon Hardy

Publication number: 20020000326Abstract: In a method of producing a composite insulator having a core member, end fitting members fixed to both end portions of the core member, and an overcoat member including a sheath portion formed on an outer surface of the core member and shed members, the overcoat member and the end fitting member are connected by curing. Moreover, a clamping operation is performed or a packing member is used for preventing a flow of an overcoat forming material into a seal portion. In this manner, it is possible to improve a seal performance of a connection boundary between the end fitting member and the overcoat member.Type: ApplicationFiled: February 5, 1999Publication date: January 3, 2002Inventors: DAISAKU GOTO, HIROSHI KASHIWAGI, TAKAO TANI

Publication number: 20010047878Abstract: The invention relates to a method for applying the main insulation of conductor bars, in particular conductor bars for stator windings, whereby the conductor bars have a rectangular cross-section. The method comprises the following steps: insertion of a conductor bar with ends in an injection mold; centering of the conductor bar in the injection mold so that a void for holding an insulation material remains between the conductor bar and the injection mold; filling of the void with an elastomer in order to form the main insulation.Type: ApplicationFiled: May 11, 2001Publication date: December 6, 2001Inventors: Albrecht Bock, Thomas Baumann, Joerg Oesterheld
