Abstract: On obtient un produit en alliage de titane présentant de bonnes caractéristiques tribologiques, sans qu'il soit nécessaire d'introduire un alliage dans la couche de surface, en coulant, ou en coulant et forgeant un alliage de titane contenant 2 à 15 % en poids de silicium ou 5 à 15 % en poids de nickel, 0 à 7 % en poids d'au moins un alliage de renforcement choisi entre aluminium, étain, zirconium, vanadium, chrome, manganèse, fer, molybdène et niobium, et 0 à 2 % en poids d'un élément d'alliage améliorant les caractéristiques de surface et choisi entre bore, carbone, azote, oxygène et zirconium, le reste, à l'exception des impuretés et d'ingrédients inhérents, étant composé de titane. Un tel alliage subit ensuite un traitement de surface consistant à faire fondre la surface et à la solidifier rapidement de façon à produire une couche de surface dure et résistante à l'usure sans affecter sensiblement les caractéristiques globales de l'alliage. Selon un autre aspect, on obtient un produit en alliage de titane, aussi bien résistant à la fatigue due au contact de roulement qu'à l'usure par frottement, en coulant ou en coulant et forgeant, sous une forme requise, un alliage de titane de préférence du type sus-mentionné, en soumettant le produit façonné obtenu à un durcissement de surface profond, à une profondeur supérieure à 100 µm et par la refonte localisée de la surface sans addition d'alliage supplémentaire, en effectuant éventuellement un finissage de surface (notamment par usinage, meulage, traitement thermique ou grenaillage du produit sous sa forme définitive requise et/ou de façon à obtenir une finition de surface requise) et en formant, directement sur la surface, un film superficiel de nitrure ou d'oxyde ou autre, d'une épaisseur ne dépassant pas 100 µm et résistant à l'usure par frottement.

Title: Method for Post Forming a Rounded Insertion End of a Tampon Pledget of an Open-Ended Applicator
Inventor: MCNELIS THOMAS C
IPC: A61F13/20
Filed: 1996-07-10
Abstract: There is provided a method for forming a round, hemispherical shape at the forward insertion end of a tampon pledget after the pledget has been assembled within a tampon applicator. The pledget is assembled within the applicator so that a portion of its fibers is exposed at an open insertion end of the applicator. After assembly, an insertion end formation tool is applied lo the exposed fibers to form a depression in the middle of the insertion end and a full periphery cushion that flares peripherally outward from the depression. The insertion end formation tool has a reverse-donut shaped curvature with a central projection or spike. The central spike reduces the axial force necessary to form the full periphery cushion by radially displacing the fibers in the central location or middle of the insertion end of the pledget. With the insertion end formed in accordance with the method of present invention, the full periphery cushion provides a rounded, forward or insertion end to facilitate an application of the tampon for its intended use.

Abstract: An arrangement in an electrical switching device for protection against electrical arcs comprises a tripping mechanism, a stationary contact carrier, a movable contact carrier, an exhaust vent, an arc runner, and an arc extinguishing barrier. The stationary contact carrier has a stationary contact mounted thereon, and the movable contact carrier has a movable contact mounted thereon. In response to an overcurrent condition, the tripping mechanism causes the movable contact carrier to rotate from a closed position to an open position, thereby generating an electrical arc. In the closed position the movable contact abuts the stationary contact, and in the open position the movable contact is separated from the stationary contact. The arc extinguishing barrier is composed of an outgassing material and is located between the stationary contact and a portion of the tripping mechanism. The stationary contact is located generally between the portion of the tripping mechanism and the arc runner such that the arc runner draws the electrical arc away from the portion of the tripping mechanism. The exhaust vent is located generally in line with the initial direction of movement of the movable contact when the movable contact carrier begins rotating from the closed position to the open position.

Abstract: A hanger for a single snowboard hangs over the top of any standard-size door, allowing the snowboard to hang vertically down the door. A J-shaped bracket hangs over top of the door and supports a two-foot length of nylon webbing which passes through a slot in the bracket, and is secured at one end with a rivet. The second end of the nylon webbing passes through a slot in the top centre of aflat baseplate and into a plastic tri-glide fastener, thus making the length of webbing adjustable. The baseplate has a series of holes drilled across its length, centered vertically. Two mushroom-shaped knobs for supporting the snowboard are screwed into the appropriate holes in the baseplate; the snowboard's width determines which holes the knobs will be screwed into. The series of holes across the baseplate will accommodate any snowboard width. The mushroom knobs should be attached to fit the width of the board about fifteen inches fromone end of the snowboard. As snowboards are wider at the ends and narrower in the middle, this allows the narrow section of the snowboard to slide between theknobs and come to rest on the knobs as the board gets wider toward the tip. Thisallows the snowboard to hang vertically on any standard-size door.
