Title: Extrusion die and method of controlling flow through the die
Inventor: MENDEL KILIAN K
IPC: B29C48/05
Filed: 1995-03-08
Granted: 2002-03-05
Abstract: An extrusion die and flow control method incorporates a flow control in the formof a flow diverter which extends transversely across the flow path. The diverter forms part of a window upstream of the die lips and provides a slight tapering enlargement which may be moved along the window across the flow path from one side to the other or preferably, from the center symmetrically outwardly, or vice versa, to divert flow from the center proportionally to the edges without changing the total cross sectional area of the window. The window is formed by a pair of axially rotatable cylindrical bars recessed in the die body which each have a flat forming the enlargement. In the preferred form the flat is helical. The helical flats are opposed or matched so that as the bars contra-rotate synchronously the enlargement will move across the window. Where the movement is symmetrical from the center or axis to each transverse edge and vice versa, the helical matching flats on each bar turn in opposite directions on each end of the middle of each bar. Where the enlargement simply moves from one transverse end of the window to the other the turn of the helix of each flat is the same from end to end of the bar, although for each of the pair, in the opposite direction. Movement of the enlargement across the flow path is obtained by axial rotation of the bar. Tandem pairs of bars may be used separately or in conjunction with each other, and may have axially inclined flats.

Abstract: A method for determining water bottom reflectivity in dual sensor seismic surveys is disclosed. The method eliminates the need for a separate survey to collect calibration data. The method involves summing the pressure and velocity signals (102), and multiplying the result by the inverse Backus operator (108), and then solving for the ocean bottom reflectivity (R) utilizing an optimization algorithm. Also disclosed is a method for combining the dual sensor data which results is the complete elimination of the first order peg-leg multiples and the modulation of the subsurface reflector strenght with the ocean bottom reflectivity. The method involves summing the pressure and velocity signals, and multiplying the result by the inverse Backus operator containing the correct value for the ocean bottom reflectivity (R) found with the method described above.

Abstract: L'invention concerne un procédé et un appareil permettant d'effectuer une commutation entre l'exécution d'une pluralité de types de codes résultants possédant différentes conventions pour appeler des procédures de programme et effectuer des manipulations de piles. L'invention peut également être utilisée pour effectuer une commutation entre différentes conventions d'appel dans un seul type de code résultant. En bref, selon l'invention, un système d'ordinateur comprend un descripteur de programme, un bloc de commutation de piles, un mécanisme de commutation de modes destiné à effectuer une commutation d'un premier processeur, d'un type de convention d'appel ou de code vers un second processeur, type de code ou de convention d'appel, et un dispositif destiné à exécuter des instructions dans divers types de codes. Un descripteur de programme décrit un segment de programme ou de code ainsi que son type de code et ses conventions d'appel. Un descripteur de programme contient, parmi d'autres informations, une zone de modes mixtes qui est réglée à une valeur prédéterminée, spécifique telle qu'une valeur indiquant une instruction qui n'est pas admise dans le cadre de la durée de l'exécution d'un premier processeur, type de code ou de convention d'appel. Lorsque cette instruction est rencontrée, la commande est transférée au mécanisme de commutation de mode. Un descripteur de programme contient également une zone d'informations de procédures qui est réglée à une valeur indiquant la convention pour appeler un segment de programme et effectuer des manipulations de piles appropriées. Lorsqu'un programme appelle un programme ayant un modèle de piles différent, le mécanisme de commutation de mode utilise un bloc de commutation de piles pour effectuer une transition entre les deux types de piles différents.

Abstract: In a process of tobacco reconstitution by extrusion a mixture of tobacco, starch and binder, with the addition of water, is extruded as a web.  The extrudate is drawn down, whereby the thickness of the web is reduced.  A minor proportion of the binder, which may be carboxymethyl cellulose, is fed to the extruder barrel in aqueous solution.  This has the effect of increasing the tensile strength of the web, so that the web can be drawn down to a greater degree.

Title: Stable complexes of crosslinked polyvinylpyrrolidone and iodine and method of making the same
Inventor: KULKARNI ARUN B
IPC: A61P17/02
Filed: 1996-06-06
Granted: 2008-01-22
Abstract: A wound treatment material which absorbs wound fluid without overdrying the wound, provides physical cushioning for the wound, and releases an antimicrobial agent (iodine) in a controlled manner to kill harmful micro--organisms without irritating the wound area or adversely affecting would healing. The wound treatment material comprises crosslinked polyvinylpyrrolidone-iodine complex which is water insoluble, but water-absorbent and water--swellable. When the complex or a wound treatment preparation containing the complex is applied to a wound, i.e., becomes hydrated, and an equilibrium is established between the complex and the wound at the wound/complex interface. Iodine is releaed from the crosslinked polyvinylpyrrolidone-iodine complex by a diffusion controlled process which responds to the reduction in concentration of free iodine in the wound fluid in equilibrium with the complex. The greater the rate of iodine depletion in the wound, the greater the rate of iodine release from the polymer-iodine complex. It has been discovered that this diffusion controlled release mechanism can be utilized to deliver antimicrobially effective amounts of iodine to the wound while maintaining the concentration of iodine below the concentration that could cause significant wound irritation or retardation of healing. It has also been found that the moist environment at the wound/complex interface and the physical protective effect (cushioning) offered by the hydrated complex can enhance wound healing.

Abstract: Dispositif (1) amélioré autonome et automatique de contrôle de la vessie qui comporte un support (2) d'ensemble vanne destiné à recevoir de manière libérable un ensemble vanne (20). Le support (2) préférablement cylindrique comporte une surface (16) externe structurée destinée à interagir avec le tissu urétral. Le support (2) peut donc être placé non chirurgicalement dans un urètre et avec le temps, l'interaction des tissus avec la surface (16) externe structurée l'empêchera de se déplacer; pourtant, il sera toujours possible de le retirer sans avoir recours à la chirurgie. Deux modes de réalisation d'ensembles vanne sont décrits, chacun permettant un fonctionnement de type sphincter de l'appareil de contrôle de la vessie. Dans un premier mode de réalisation, la loi de Bernoulli est utilisée pour garder la vanne ouverte après une courte période de contraction musculaire. Le deuxième mode de réalisation fait appel au fait que la force produite par la pression hydrostatique est directement proportionnelle à la surface à laquelle elle se heurte, pour obtenir la durée désirée d'ouverture de la vanne.

Abstract: It is an object of the present invention to provide a variable attenuator which can be produced at a low cost and can suppress production of unnecessary resonance and propagation. When the radio frequency resistance values of PIN diodes 13 and 14 are higher than a characteristic resistance value of a signal line interconnecting radio frequency signal input terminal 1 and radio frequency signal output terminal 2, the sum of voltages applied to PIN diode 11 and PIN diode 13 and the sum of voltages applied to PIN diode 12 and PIN diode 14, that is, V3, are controlled so as to be fixed. But when the radio frequency resistance values of PIN diodes 13 and 14 are lower than the characteristic resistance value of the signal line, the currents to flow through PIN diodes 13 and 14 are fixed to such values with which the radio frequency resistance values and the characteristic resistance value of the signal line are equal to each other while only the currents to flow through PIN diodes 11 and 12 are controlled to vary the attenuation amount.
