Title: Transparent wound dressing
Inventor: CARTMELL JAMES V
IPC: A61F13/00
Filed: 1990-10-19
Granted: 1995-03-28
Abstract: A flexible, transparent wound dressing product contains a clear hydrogel material in a gel-like phase. The wound dressing product is comprised of several layers including a wound dressing, a release layer, and a dimensionally stable backing member.  The wound dressing is comprised of a thin-film transparent layer having an adhesive perimeter portion and a center portion, and a hydrogel material positioned in the center portion of the transparent layer.  Since the wound dressing is transparent, a grid pattern may be printed on the thin-film transparent layer to permit measurement of a wound.  During manufacture, a vacuum pressure is applied to allow temporary access to the center portion of the thin-film transparent layer, creating a cavity for insertion of the hydrogel material.  The dimensionally stable backing member is then adhesively attached around the perimeter portion of the thin-film transparent layer to help the wound dressing maintain its shape.  When the wound dressing product is to be applied to a wound site, the release layer is removed, preferably using an extending tab attached thereto, to expose the hydrogel material.  The remaining layers of the wound dressing product are then applied to the wound site, with the hydrogel material directly contacting the wound. Once these layers are in place, the dimensionally stable backing member is removed, preferably using an extending tab attached thereto.

Abstract: Un procédé pour étirer un ensemble, par exemple un ruban ou une mèche, de fibres discontinues non retordues (12), afin de réduire leur diamètre et d'accroître leur longueur, met en oeuvre une fausse torsion pour permettre une friction entre les fibres en vue d'assurer la réalisation d'un étirage des fibres et non d'un étirage de l'ensemble. Les fibres sont premièrement plastifiées par traitement avec un agent approprié dans un bain (16) puis elles passent dans un appareil utilisant un certain nombre d'agencements rotatifs (24, 25, 29, 32) de galets menés (26, 33). Ces agencements sont montés pour tourner entre deux points de contact de blocage pour le tordage (18, 18') et sont rotatifs autour d'un axe longitudinal correspondant au sens de déplacement de l'ensemble dans l'appareil pour imprimer une fausse torsion dans ledit ensemble. Ce dernier est étiré entre deux des agencements de galets (24 et 25), les galets de l'agencement aval (25) étant entraînés à une vitesse supérieure aux galets de l'agencement amont (24). L'étirage est ensuite fixé par chauffage à la vapeur dans une chambre (17) tandis que la fausse torsion est maintenue par d'autres agencements de galets rotatifs (29). Des étapes de traitement ultérieur (14, 46) peuvent être ajoutées pour stabiliser davantage les fibres étirées. Les fibres sont des poils animaux, par exemple de la laine.

Title: Thermal response switch and a surge absorbing circuit using the same
Inventor: IKEDA FUJIO
IPC: H02H9/04
Filed: 1992-06-25
Granted: 1997-12-23
Abstract: A surge-absorbing element is parallel-connected to an electronic device via a pair of communication lines. A normally-closed thermal-response switch is serially-connected between the electronic device and the signal sourceon the input side of the surge-absorbing element. When a surge voltage is instantaneously applied to the communication lines, the thermal-response switch remains in the closed position and the surge-absorbing element acts to suppress the surge voltage. When an overvoltage or overcurrent is continuously applied to the communication lines, thermal-response pieces of the thermal-response switch open to release the movable body. The electronic device is thereby disconnected from the signal source, thus stopping the overvoltage or overcurrent from continuing to flow to the electronic device and the surge-absorbing element. Simultaneously, a reset pin is projected through the casing. After the temperature of the switch decreases, the switch is reset to the closed position by pushing the reset pin, which reconnects the electronicdevice to the communication lines.

Abstract: A box forming apparatus for forming a box from a pressed cardboard blank which has been introduced on a forming matrix. The apparatus has two rectangular end plates joined together by a bridge by means of a guide and bolt system in each plate. The guide and bolt system permits variation and adjustment of the height of the apparatus with regard to the machine support. Two winged plates are pivotally attached between the end plates, the winged plates pivoting freely without the aid of pistons or springs. The respective axes of rotation of each of the wings is located at their respective top edges. The pivoting of the wings is delimited by round profiles, or stops, located on the end plates at two separate locations. One set of the stops prevent motion inward towards the center of the end plates, while a second set of stops prevent motion outward away from the center of the end plates. The wings have a bevelled bottom edge for relatively free sliding motion as the wings contact the cardboard blank.
