Patent number: 5295908Abstract: A fluid friction coupling comprises a coupling hub (1) and a coupling housing (2) rotatably supported on the coupling hub. The coupling also comprises sets of plates (6; 7) non-rotatably mounted on the hub and housing. One set of plates has spacing teeth (8) which, while eliminating the previously used spacer rings, permit accurate spacing of the set of plates. A predetermined number of spacing teeth (8) of the axially immovable plates (7) are bent out of the plane of the respective plate so as to be Z-shaped with both bending angles approximately 90 degrees. This measure ensures that the plates for a friction coupling are designed in such a way that they are accurately spaced at predetermined distances and that they are suitable for automatic assembly purposes.Type: GrantFiled: June 2, 1993Date of Patent: March 22, 1994Assignee: Viscodrive GmbHInventors: Siegfried Schumann, Wolfgang Gimpel

Patent number: 5265820Abstract: A cassette shell consists of two shell halves, and rotatably contains a spool core on which a photographic film is wound. A pair of spool flanges are loosely fitted on the spool core. Rotation of the spool core causes a film leader to advance through a film passage slit. A melting point of resin for molding the spool flanges is different from that of resin for molding the cassette shell for the purpose of avoiding undesired ultrasonic welding on their contact surfaces when joining the shell halves. The spool flanges are molded from material including polyolefin resin having a high density and a high molecular weight in order to reduce friction against the cassette shell and the photographic film.Type: GrantFiled: November 26, 1991Date of Patent: November 30, 1993Assignee: Fuji Photo Film Co., Ltd.Inventor: Masahiro Enomoto
