Patent GB-2232921-A (GB)
Title: Tape-applying method and means
Inventor: LACK BRYAN JAMES
IPC: G03C3/00
Filed: 1990-06-08
Abstract: The cut edges of sheets, in particular, X-ray film plates (P) cut from a continuous roll, are covered by a tape (T) (e.g. light-tight adhesive tape) using an apparatus in which each sheet (P) is held on a support (30) with an edge to be covered clear of that support and a length of tape over the edge. A carriage (42) moving transversely to the sheet edge carries a pair of rollers (56) on axes parallel to the edge. The rollers are rotated in synchronism with the movement of the carriage so that as the carriage is brought to the cut edge the rollers roll the tape onto the margins at opposite sides of the edge as the tape and sheet pass through the nip of the rollers. Surplus ends of the tape are trimmed by cutting means (78) that are also mounted on the carriage. Suction cups 82 hold the sheet P during application of tape. The sheet is cut into plates before being applied with tapes. The cutting and tape applications may be undertaken in a light-tight enclosure. <IMAGE>

Title: Joining shoe components with adhesive
Inventor: BOYLAN JAMES
IPC: A43D25/047
Filed: 1991-11-26
Abstract: A process for production of shoes is illustrated. A lasted margin (3) is roughened by grinding and portion (2) of the edge of a lasted upper (1) is roughened using a machine (10) having serrated discs (13) mounted loosely on rotating support rods (14). The inside margin of a sole is roughened using a vertical grinding insert (24) mounted above a drive wheel (21) for guiding the inside margin of the sole against the grinding insert (24). Bonding of the upper to the sole is achieved by initially applying a primer coat of adhesive and allowing this to dry. Subsequently, an adhesive\hardener mixture is applied and allowed to dry. When bonding is to take place, both the primer and the adhesive\hardener mixture are re-activated by heating. The upper and sole are pressed together using inflatable cushions to create an even pressure. <IMAGE>

Title: Capacitive micromachined differential pressure sensor
Inventor: MASTRANGELO CARLOS HORACIO
IPC: B23P15/00
Filed: 1994-01-21
Abstract: A surface layer and a sacrificial layer are deposited on a substrate. A conductive structural layer bridges over the sacrificial layer and is anchored to the surface layer for creating paired conductive areas.
