Abstract: Apparatus for feeding boards in a single direction sequentially from the bottom (or top) of a stack through a feed gate, comprising three parallel rows of frictional contact conveying wheels (24) each row driven by a separate electric motor (21, 22, 23). The boards (12) are fed sequentially onto an output conveyor (1) without nip rolls. An electronic control system (27) accelerates the three rows of wheels (24) simultaneously to line speed and progressively decelerates each row of wheels when the trailing edge of each board has advanced and before the next succeeding board has descended. The conveying wheels (24) project through apertures in a suction box (16) which holds the boards in contact with the conveying wheels during conveyance. The boards are fed without crush accurately and in perfect register without slipping and with minimum power requirements.

Abstract: An ultrasonic surgical scalpel comprising a suction nozzle (4) having a suction mouth (4b, 14b, 24b, 34b) which is open aside toward the direction different from that of the axis (X) of the nozzle (4), and a suction regulating mouth (7) formed in a suction pipe extending from the suction nozzle (4) so as to communicate with a suction passage (4a) inside the suction nozzle. The suction mouth (4b, 14b, 24b, 34b) being open aside allows the leading end of the nozzle (4) to be made acute or round, thereby to enable the suction nozzle to be readily inserted and moved in subcutaneous or organic tissues while shattering the tissues with ultrasonic vibrations. When sucking out the tissues shattered with the vibrations, by selectively opening and closing the suction regulating mouth (7) with a finger tip, sucking force for sucking out the tissues can be freely controlled with ease.

Abstract: An optical fiber transmittion medium includes optical fiber (21) provided with a coating system (31) typically including two layers each of a different coating material. An inner layer (32) of a first coating material is called the primary coating and an outer layer is termed the secondary. In order to achieve desired performance characteristics, performance is related to properties of a coating system. The coating materials have well defined moduli and the second coating material has an elongation which is substantially less than in prior secondary coating materials. Adhesion levels which are optimized rather than maximized are substantially stable with respect to time. Curing of the coating materials may be accomplished simultaneously or in tandem with the application separately of the coating materials.
