Abstract: PRÉCIS Les équipements existants pour couper le tabac en feuille pour des fins d'usage person-nel sont trop coûteux ou encore ils demandent beaucoup de temps lors de l'opération et, dans ce cas, la qualité du produit obtenu laisse à désirer. La présente invention consiste en un outil que l'on fixe à un outil tournant manuel ou motorisé, par exemple une perceuse électrique. L'invention en question, le coupe-tabac, consiste en une lame qui est fixée à un disque de polyéthylène. Lorsque l'outil est mis en rotation, le mouvement de la lame se fait de telle façon que son angle de coupe attaque le tabac de manière à produire de fines tranches de tabac. Les particularités de la présente invention sont sa simplicité d'utilisation et son faible coût, ce qui la rend accessible à un grand nombre d'usagers.
Patent CA-2068562-A1 (CA)
Title: Cleaning methods
Inventor: BITTLESTON SIMON H
IPC: E21B33/14
Filed: 1992-05-13
Abstract: Once the drilling of an oil or gas well is finished the bore must be cased and cemented. It is important that the cement lining be complete, and to ensure this it is necessary to sweep out the mud in the annulus ahead of the rising cement. Unfortunately, this often proves difficult, and various procedures and mechanisms have been devised in the past to improve the chances of achieving efficient mud-removal and forming a complete cement lining, though none have been truly successful. One of the techniques presently employed involves the utilisation of a wash, but it has been noted that such a wash, even when turbulent, has very little component of its movement in the annulus in a direction other than up along the annulus, and that as a result it has very little effect on gelled mud deposits, especially those in the small casing/bore inter-distance of a severely eccentric casing.  It has now been discovered that a considerably increased amount of lateral motion, and thus a very significantly enhanced degree of mud removal capability, is provided if the liquid be a multiphase liquid in which one of the phases is a gas - in other words, if the liquid be full of bubbles - and the invention provides a cleaning method particularly suitable for the cleaning of gelled mud deposits off the casing and bore walls of an oil/gas well prior to cementing the casing in place, in which there is caused to flow over and in contact with the dirty surface a "burbulent"  liquid.

Filed: 1992-06-03
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for distinguishing between hydrogen damage in the wall of a boiler tube, and surface damage on the inside surface of the tube, comprises a pair of transducers which are spaced on the outer surface of the tube and which apply a refracted shear ultrasonic wave through a chord of the tube with a beam angle that is calculated from the outside radius and wall thickness of the tube.  The transducers are first applied to an undamaged tube and an instrument connected to the transducers is adjusted to 80% of full screen height.  The same transducers are then applied to a suspected boiler tube.  Any attenuation of the initially high amplitude below 12 dB indicates hydrogen damage as opposed to inner surface damage which has been found to produce a far lower attenuation.

Title: Method and system for compressing video data
Inventor: LANEY STUART T
IPC: H04N19/593
Filed: 1993-12-21
Abstract: A METHOD AND SYSTEM FOR COMPRESSING VIDEO DATA                 Abstract of the Disclosure A  method  for  compressing  video  movie  data  to  a specified  target  size  using  intraframe  and  interframe compression schemes.   In intraframe compression,  a frame of the movie is compressed by comparing adjacent pixels within the  same  frame.     In  contrast,   interframe compression compresses by comparing similarly situated pixels of adjacent frames.   The method begins by compressing the first frame of the video movie using intraframe compression.  The first stage of the intraframe compression process does not degrade the quality of the original data, e.g., the method uses run length encoding based on the pixels'  color values to compress the video  data.     However,  in  circumstances  where  lossless compression is not sufficient, the method utilizes a threshold value, or tolerance, to achieve further compression. In these cases,  if the color variance between pixels is less than or equal to the tolerance, the method will encode the two pixels using a  single color value  -- otherwise,  the method will encode the  two pixels  using different  color values.    The method  increases  or  decreases  the  tolerance  to  achieve compression  within  the  target  range.     In  cases  where compression within the target range results in an image of unacceptable quality, the method will split the raw data in half and compress each portion of data separately.   Frames after  the  first  frame  are  generally  compressed  using  a combination   of intraframe   and   interframe   compression. Additionally,  the method periodically  encodes  frames  using intraframe compression only in order to enhance random frame access.

Abstract: A method for the direct treatment towards the specific sites of a disease is disclosed. This method is based on the delivery of proteins by catheterization to discrete blood vessel segments using genetically modified or normal cells or other vector systems.  Endothelial cells expressing recombinant therapeutic agent or diagnostic proteins are situated on the walls of the blood vessel or in the tissue perfused by the vessel in a patient. This technique provides for the transfer of cells or vectors and expression of recombinant genes in vivo and allows the introduction of proteins of therapeutic or diagnostic value for the treatment of diseases.
