Title: Endotracheal tube having ventilation means
Inventor: PECKHAM KEITH A
IPC: A61M16/00
Filed: 1991-10-10
Abstract: The present invention relates to an endotracheal tube (10) used for mechanical ventilation of a hospital patient, the endotracheal tube having means to evacuate contaminated secretions that pool within the trachea above an inflatable cuff (14) associated with the endotracheal tube.

Title: Disk Clamping Device for Magnetic Disk Drive
Inventor: IWABUCHI MASANORI
IPC: G11B17/02
Filed: 1993-11-16
Abstract: A disk clamping device in a magnetic disk drive includes a clamper which presses an uppermost one of a plurality of magnetic recording disks and a clamping force transmission member which presses the clamper against the uppermost magnetic recording disk. A material having a small Young's modulus, such as a high polymer material and a super elastic material, is used for the clamper or the clamping force transmission member, or both of them. The device may include a shim whose Young's modulus is larger than that of the clamper which presses the uppermost disk through the shim. The arrangement makes it possible to reduce the variations in the clamping force caused by a lack of manufacturing precision or a change in temperatures and to provide a stable clamping force. The uniform clamping force enables to reduce the occurrence of undulation in the disks otherwise caused by the circumferential clamping force differences in the clamper.

Title: Method and apparatus for scrolling asian brush painting and calligraphy
Inventor: KUO NUNG
IPC: B32B29/00
Filed: 1994-09-19
Abstract: Heat and pressure are used to bond delicate tissue paper artwork to scrolling materials. The tissue paper has relatively little strength in any direction and is therefore subject to tear, buckle, bubble, crumple or smudge if handled improperly. A backing panel and a matting panel are aligned and partially fed through a machine that applies heat and pressure perpendicularly to its feedpath. The artwork side of the tissue paper is covered with a paper liner for protection and the covered tissue paper is sandwiched between front and back dry mount sheets. These four layers are inserted into a head-board-piece and then sandwiched between the unadvanced portions of the backing panel and the matting panel. The whole sandwich is then advanced through the machine wherein the heat and pressure bond the tissue paper to the backing panel and the matting panel to the paper liner and the backing panel. A window is cut through the matting panel, the front dry mount sheet and the paper liner to reveal the art on the tissue paper, excess or uneven edges are trimmed, and the scroll is framed.
