Patent number: 8187484Abstract: The invention relates to a process for etching a substrate (3) in an etching chamber (1) with a plasma ignited outside of the etching chamber (1). The process is characterized in that during the etching process at least temporarily at least one gas jet (10) is directed from the side to the radical stream (7) which is directed towards the substrate (3). Furthermore the invention relates to an etching chamber for etching of a substrate (3) with a substrate holder (2) and a plasma source (4) remote to the substrate holder (2), which is characterized in that between the substrate holder (2) and the plasma source (4) at least one nozzle (9) for lateral introduction of a gas jet (10) into the etching chamber (1) is provided. With this invention the distribution of the active species on the surface of a substrate can be easily influenced.Type: GrantFiled: October 5, 2005Date of Patent: May 29, 2012Assignee: PVA TePla AGInventor: Jeff Alistair Hill

Patent number: 6434885Abstract: A movable window unit having a window glass which can be moved between a closed end position in a well of a door and an open end position by a motorized drive. The motorized drive comprises an electric motor which is controlled by a motor control. To reduce undesirable noises which may arise during the movement of the window glass, the motor is operated by the motor control to repeatedly vary the speed of displacement of the window glass.Type: GrantFiled: July 30, 1999Date of Patent: August 20, 2002Assignee: Meteor Gummiwerke K.H. Bädje GmbH & Co.Inventor: Alistair Hill

Patent number: 6073936Abstract: A vehicle seal (1) comprises an elastic molded sealing member (19) with holes through which clips (16) on a fastening rail (11) made of plastics material extend into anchoring holes in a vehicle body. The molded sealing member (19) is made in a molding tool (2) by being injected on to and vulcanized to the fastening rail (11) which is laid within the molding tool. The molding tool (2) is divided and includes a molding recess (8) in which the fastening rail (11) is laid. On one mold part (6), for each clip (16), there is provided a cap (9) which sealingly encircles the clip (16) and which extends into the molding recess (8) when the molding tool (2) is closed. Each cap (9), when the molding tool (2) is closed has its free edge (18) pressed into sealing contact with a base (12) of the fastening rail (11) which carries the clips (16). A coupling layer (15) is provided between the fastening rail (11) and the molded seal (19).Type: GrantFiled: June 7, 1995Date of Patent: June 13, 2000Assignee: Meteor Gummiwerke K.H. Badje GmbH & Co.Inventors: Gunter Kirchmann, Hans-Volker Buchholz, Alistair Hill

Patent number: 6030022Abstract: The sealing profile (5) comprises an inherently stable carrier rail (7) which is injection-coated over a part of its periphery with an elastomeric profile strip (8). On a peripheral portion (10) without elastomer lie heads (9) of fixing members (6) which are screwed into roof guides (4) of the folding soft top (2). Sealing lips (17, 18) take care of the sealing in relation to a side window (21). A further sealing lip (22) effects sealing in relation to the roof cover (24).Type: GrantFiled: December 19, 1997Date of Patent: February 29, 2000Assignee: Meteor Gummiwerke K. H. Badje GmbH & Co.Inventors: Josef Bormann, Jens Anders, Alistair Hill

Patent number: 5736215Abstract: A compound profile (43) consists of a fastening section (33) of a thermoplastic plastics material as well as profile sections (30, 31) of elastomeric material, namely a profile section (30) of expanded rubber and a profile section (31) of soft rubber. All sections (30, 31, 33) are fixed to one another by co-extrusion and co-vulcanization. The plastics material fastening section (33) assumes the function of the conventional metallic reinforcement of the compound profile (43). The compound profile (43) can be three-dimensionally shaped in that it is heated up to the plasticization temperature of the fastening section (33), then is brought to the desired shape in a shaping tool, and in that shape is cooled until the fastening section (33) has again returned to its non-plastic state. One thus creates a profile part which is stable in shape.Type: GrantFiled: January 11, 1996Date of Patent: April 7, 1998Assignee: Meteor Gummiwerke K.H. Badje GmbH & Co.Inventors: Hans-Volker Buchholz, Alistair Hill

Patent number: 5562961Abstract: A compound profile of thermoplastic plastics material and elastomeric material. The thermoplastic plastics material and elastomeric material are chemically bonded by co-vulcanization. A coupling material can be used to promote the chemical bonding.Type: GrantFiled: December 29, 1994Date of Patent: October 8, 1996Assignee: Meteor Gummiwerke K. H. Badje GmbH & Co.Inventors: Hans-Volker Buchholz, Alistair Hill
