Rigid bars 25 restrict the flexibility of the shank parts into one plane.
Patent CA-2222054-A1 (CA)
Title: Method of forming tungsten carbide particles
Inventor: GAO LIN
IPC: C01B32/949
Filed: 1997-11-25
Abstract: Nanograined tungsten carbide particles are formed by a controlled, simultaneous reduction carburization reaction wherein the kinetics of the carburization and reduction reactions are controlled to permit simultaneous reduction and carburization. The kinetics are controlled by reacting a reduction carburization gas mixture, preferably hydrogen and carbon monoxide by slowly increasing the reaction temperature by controlling the rate of temperature increase. Preferably, the reaction temperature will be increased less than 25° C per minute, preferably about 1-2 degrees per minute, which prevents the formation of stable, undesirable species such as W2C, which in turn interferes with the reaction efficiency.

Filed: 1996-06-05
Abstract: Des cellules destinées à l'implantation chez un patient qui en a besoin sont encapsulées avant implantation dans une barrière immunoprotectrice, ce qui empêche ou minimise leur rejet. Le tissu immunoprivilégié préféré pour la constitution de cette barrière est le cartilage. Ce tissu est mis sous la forme d'une couche suffisamment fine pour permettre la diffusion de nutriments et de gaz au centre de la masse cellulaire placée à l'intérieur de la barrière immunoprotectrice, d'une épaisseur typiquement inférieure à 300 microns et comprise de préférence entre 5 et 20 microns. Les cellules destinées à l'implantation, généralement des cellules parenchymateuses prélevées, qui peuvent être des hépatocytes, des ilôts de Langerhans ou d'autres cellules possédant des fonctions métaboliques, sont ensuite déposées sur la barrière, qui est repliée afin d'enfermer à l'intérieur les cellules destinées à être implantées. Dans le mode réalisation préféré de cette méthode, les cellules prélevées sont d'abord ensemencées dans une matrice de fibre polymères. Puis les cellules encapsulées sont implantées à un endroit où la barrière permet l'apport approprié de sang et donc la diffusion des nutriments et des gaz, par exemple un endroit adjacent au mésentère. L'exemple donné concerne l'encapsulage d'ilôts de Langerhans à l'intérieur d'une barrière formée par une mono couche de chondrocytes ensemencés dans des fibres polymères.

Title: Generation of sweepout motion profile in an individual section glassware forming system
Inventor: HENNING JEFFERY P
IPC: C03B9/453
Filed: 1998-05-12
Abstract: In an individual section (IS) glassware forming system that includes a plurality of operating mechanisms for performing cyclic motions, an electronic controller for controlling cyclic motion of at least one of the operating mechanisms includes an electronic memory for storing a plurality of motion profiles for the one operating mechanism, with each of the profiles comprising a set of motion data versus time data. Each of the profiles has a piecewise linear contour determined by a plurality of control points, with each of the control points having associated motion and time data values. The operator may selectively display one of the profiles as a table of time values for the control points, with the time values preferably being in units of IS machine degrees. The operator may change the time values associated with one or more of the control points, and the controller automatically recomputes the motion data versus time data for the entire profile as a function of a change in time data by the operator at at least one of the control points, while maintaining the piecewise linear contour of the overall profile. Operation of the operating mechanism is thereafter controlled as a function of the recomputed motion versus time profile data.
