Granted: 2003-04-08
Abstract: A pneumatic tire which is used for a vehicle and obtained after a rubber material is formed by vulcanization. A cap portion (12A), which is an upper layer of a tread and directly contacts the road surface, is a foam rubber which includes innumerable elongated closed cells (24). The outer portion of the elongated closed cell (24) is coated by a resinous protective layer (26). During the vulcanization process of the tire, a resin whose viscosity is lower than that of a rubber matrix and a blowing agent which generates gas are kneaded with a rubber material so as to obtain a rubber composition. The rubber composition is formed in the shape of a band and adhered to a crown portion of a raw tire casing. The resin is melted by the heat of vulcanization and the viscosity of the resin is lower than that of the rubber matrix. The gas generated in the rubber moves toward and concentrates at the inner side of the resin. Accordingly, an elongated closed cell (24) whose outer portion is provided with the resinous protective layer (26) is formed.

Title: Method of determining fluid inflow rates
Inventor: ALEXANDER LLOYD G
IPC: E21B47/00
Filed: 1998-03-12
Granted: 2006-05-30
Abstract: A method is provided for determining the actual inflow rates of gas and liquid into a wellbore from a reservoir. The wellhead is first closed and the wellhead pressure is measured over time. For a briefly period, gas is flowed from the wellhead and the wellhead pressure is measured again. Using the two conditions, the original wellbore gas volume and an original fluid inflow rate is determined. Gas is again flowed from the wellhead, both the flow and the pressure being measured, but this time for a prolonged duration, sufficient to affect the reservoir. Assuming the original gas inflow rate and original gas volume remain unchanged during the prolonged flow, a total rate of fluid inflow from the reservoir is determined, and finally an incremental inflow rate of fluid from the reservoir is calculated as being the difference between the total rate of fluid inflow less the original rate of gas flow. If the well is a gas well, the incremental fluid inflow is the actual gas inflow rate. If the fluid inflow is known to be liquid, then an incremental change in volume is equivalent to the liquid inflow rate. Using an exponential relationship for the pressure change during wellhead flow, a theoretical curve pressure response curve can be created, displayed and compared against the actual pressure response, any deviation therebetween being indicative of fluid inflow from the reservoir.

Abstract: Un amplificateur différentiel hyperfréquence comprend des premier et second dispositifs CMOS adaptés, chacun étant connecté par la source à un noeud de polarisation commun, par la grille à un port d'entrée pour recevoir un signal d'entrée différentiel et par les drains à un port de sortie, pour émettre un signal différentiel de sortie. Des condensateurs Miller de chaque dispositif assurent la rétroaction nécessaire entre les ports d'entrée et de sortie, pour décaler de 45· la phase du signal différentiel de sortie, par rapport à la phase du signal différentiel d'entrée, à une fréquence prédéterminée. Le point de fonctionnement des dispositifs NMOS est maintenu dans une région linéaire de la caractéristique de transfert respective, à l'aide de charges adaptées et d'un courant de polarisation correspondant. Les charges peuvent être des résistances, auquel cas on utilise une commande de gain automatique pour conserver un courant de polarisation constant, ou des charges actives. Un oscillateur, commandé en tension et réalisé avec quatre de ces amplificateurs différentiels dans une configuration de gyrateur, oscille à la fréquence prédéterminée et possède huit signaux de sortie. L'oscillateur commandé en tension peut être utilisé dans des circuits assurant une régénération des données polyphasées, où le nombre de transitions de données dépasse le nombre de transitions d'horloge, pendant une durée donnée.

Abstract: A closed-loop ultrasonic welding apparatus for sealing or welding thermoplastic material on a continuous basis wherein the material to be welded is fed through a weld station comprising a horn and anvil. The apparatus includes means for providing a first signal commensurate with a desired ultrasonic energy density in the material when welded, a second signal responsive to the feed speed of the material through the weld station, and a third signal commensurate with the power coupled by a power supply via a transducer and the horn to the material at the weld station. Control means receive the first, second and third signals and produce an error signal, which is responsive to the difference between the desired energy density and the actual energy density coupled to the material. After being subjected to further processing the error signal is converted to a control signal for controlling the output from said power supply and/or controlling the engagement force between the horn and material. Hence, the welding apparatus causes a predetermined energy density in the welded material irrespective of disturbances or changes in feed speed, engagement force between the horn and material, or the material itself.

Abstract: A self aligning, low or no self-torque club that is both statically and dynamically balanced is provided which is less prone to deleterious effects during its approach to and in the course of striking the ball and which enables the club head to be more square at the point of impact more often. Static balance is achieved by ensuring the longitudinal axis of the shaft intersects the line between the geometric center of the club face and the center of gravity of the club head. The club is self-aligning because the center of gravity naturally follows the shaft, the point of application of force on the club head, and since the shaft and center of gravity are in line with the center of the club face, the possibility of striking the ball with the club face square increases. By providing a symmetrical and, preferably elliptical face, forces due to air resistance act equally on both sides of the face with respect to the shaft further aligning the club face with the swing path of the club head. The club head may also be provided with a series of convergent longitudinal channels in the direction of air flow over the club to further align the club head. The channels serve to stabilize the club head during downswing and move the center of pressure toward the rear of the club and as far behind the axis of the shaft as possible and, preferably, in-line with the center of gravity and the club face. The symmetrical nature of the club head permits, in one embodiment, the same club head to be used for right- or left-handed golfers. Also provided is a set of clubs according to the invention, which due to their similar static and dynamic balance and similar shape and configuration, provide a similar feel and play throughout the entire range of lofts.

Abstract: A water jet cutting apparatus for use in a papermaking machine has an elongated support beam that extends across the width of the web. The water jet cutting apparatus utilizes a free spinning hose wheel about which the water jet hose supplying water to a water jet nozzle is guided and stretched. The wheel is mounted for movement with a slower moving carriage along the beam adjacent a faster moving carriage carrying the water jet nozzle. The slower moving carriage moves along the beam at speeds which are one half the speeds at which the faster moving carriage moves across the beam. During this movement of the second slower moving carriage, the wheel reels the hose thereabout to provide a travelling intermediate support for the hose. The hose wheel supports the weight of the hose and maintains it in alignment with the faster moving carriage so that less strain and stress is placed on the hose and the ends of the hose connected to the water jet nozzle during movement of the water jet nozzle across the beam. The water jet cutting apparatus has a preferred application as a tip cutting device in a reel turn-- up application in a papermaking machine when two sets of faster and slower moving carriages are arranged for movement on opposite sides of the support beam to move towards each other in directions transverse to the web.
