Title: High Pressure Seal
IPC: F16J15/32
Filed: 1978-10-19
Abstract: Packing 33 for use in sealing high pressure installations includes a deformable seal ring 35 integral with a backup ring 37 of greater hardness and smaller diameter. The packing is placed in an annular clearance area 31 between coaxial members 11, 15 with the seal ring 35 under pressure engaging confronting surfaces of the members. The backup ring 37 prevents extrusion of the seal ring into the clearance 43 between the members and helps to maintain alignment between these members. Interlocking means can be integrally formed in the process of molding the seal backup rings to help maintain their integrity after molding. The packing can be made in long lengths from which an appropriate length can be cut and its ends joined to form a ring of the desired diameter. This also enables the packing to be introduced into the clearance area between members without requiring disassembly of those members. <IMAGE>

Title: Film Scanner
IPC: H04N5/253
Filed: 1979-03-21
Abstract: In continuous motion film scanning apparatus of the flying spot type for producing video signals each film frame is scanned at least twice, successive scans being interlaced vertically.

Title: Controlling sheet feed to a printing machine
IPC: B65H7/04
Filed: 1981-02-26
Abstract: Sheet feed to a printing machine 5 is controlled by monitoring a sheet fed to a registration line 3 of the machine and evaluating the monitoring signals at two different evaluating times per machine cycle. On detection of a correct sheet at the first evaluating time, evaluation at the second evaluating time is withheld and the sheet is released to enter the printing press. If, however, a skewed sheet is detected at the first evaluating time the sheet conveying is interrupted for one cycle and evaluation at the second evaluating time is withheld. Thereafter, on detection of a correct sheet at the first evaluating time of the succeeding cycle, evaluation at second evaluating time is withheld and the sheet is released to enter the machine, or on detection of a skewed sheet at the first evaluating time of the succeeding cycle the sheet conveying is stopped. If no sheet is detected at the first evaluating time, evaluation is carried out at the second evaluating time and, on detection of a correct or skewed sheet, the sheet conveying is interrupted for one cycle and evaluation is carried out at the first evaluating time of the succeeding cycle. If a skewed or lacking sheet is detected in any subsequent cycle, any such sheet is prevented from entering the machine and sheet conveying is stopped. <IMAGE>

Title: Method of making colour patterns on material
IPC: D06B11/00
Filed: 1981-06-03
Abstract: A printing ink is applied to one side of a continuously moving fabric (1) which is then driven between rolls (4 and 5) so that the ink is distributed and, at the same time, a pattern is created by providing the roll (5) on the opposite side of the fabric with relief areas.
