Title: Technique for object orientation detection using a feed-forward neural network
Inventor: MORRIS ROBERT J T
IPC: G06T7/00
Filed: 1990-03-29
Abstract: A TECHNIQUE FOR OBJECT ORIENTATION DETECTION      USING A FEED-FORWARD NEURAL NETWORK          Abstract The present invention relates to a technique in the form of an exemplary computer vision system for detecting the orientation of text or features on an object of manufacture. In the present system, an image of the features or text is used to extract lines using horizontal bitmap sums, and then individual symbols using vertical bitmap sums, using thresholds with each of the sums. The separated symbols are then appropriately trimmed and scaled to provide individual normalized symbols. A Decision Module comprising a Feed-Forward Neural network and a sequential decision arrangement determines the "up", "down" or "indeterminate" orientation of the text after a variable number of symbols have been processed. The system can then compare the determined orientation with a database to further determine if the object is in the "right-side up" "upside-down" or "indeterminate" orientation.

IPC: A61M29/02
Filed: 1990-05-23
Abstract: An intravascular catheter designed to apply a liquid medicament or other substance to a stenotic lesion as the blood vessel is undergoing dilatation to facilitate the restoration and long-term maintenance of patency to the blood vessel.   It comprises three concentrically arranged  flexible  plastic  tubes  and  a  pair  of concentrically arranged expander members located at the distal end of the tubes.  The space between the outer wall of the inner tube and the inner wall of the intermediate tube is in fluid communication with the interior of the first expander member while the space between the outer wall of the intermediate tube and the inner wall of the outer tube is in fluid communication with the interior of the second expander member.   A plurality of minute holes are formed through the second expander member such that when the liquid medicament is introduced into the lumen of the outer tube while an inflation fluid is introduced into the lumen of the intermediate tube, both expander members inflate with the drug or other substance being ejected out through the tiny pores of the outermost expander member while continued  inflation  of  the  inner  expander  member provides the necessary pressure for dilatation of the lesion.

Title: Fluid control device for removal of well tubing from a well
Inventor: GREUPNER TERRY
IPC: E21B23/04
Filed: 1990-06-15
Abstract: FLUID CONTROL DEVICE FOR REMOVAL OF WELL TUBING FROM A WELL       ABSTRACT OF THE DISCLOSURE              A  fluid  control  unit  is designed  for  use  in removing wet tubing from a well and comprises a substantially closed box with a hole in the top and bottom plate and which is mounted a sealing rubber.

Abstract: A thermal transfer sheet having a back coating layer excellent in heat-resistance is provided by using a styrene-acrylonitrile  copolymer  as  a  resin constituting  the  back coating  layer.   A  thermal  transfer  material  having  an excellent  heat-resistance and having a back coating layer having considerable strength is provided by incorporating at least   two  species  of  heat-resistant  particles  having different particle sizes in the back coating layer,  since the  larger  species  of  particle  imparts  excellent  heat-resistance to the back coating layer, the smaller species of particle enhances the total amount of the fillers, and the larger and smaller species of particles function so as to provide  a  synergistic  effect.   A  thermal  transfer  sheet having  a  back  coating  layer  which  is  excellent   in storability is provided by incorporation an alkylphosphate multi-valent metal salt into the back coating layer, since the thus prepared back coating layer has an excellent heat-resistance,  does not contaminate another menber or thermal head without wearing the thermal head, and has an excellent slip property and an excellent dye barrier property.

Patent CA-2025853-A1 (CA)
Inventor: DYSART THEODORE R
IPC: E21B10/25
Filed: 1990-09-20
Abstract: This invention relates to a rotary drill bit having a body with leg members, where each of the leg members has a projecting conical cutter receiving journal.  A conical cutter having an axially extending recess open at one end has friction reducing bearings interior to the conical cutter for rotatably mounting the cutter on the journal.  A plurality of lubricant carrying conduits interior to the leg members extending into the bearings provides lubricant for the bearings.  This invention provides an improved sealing arrangement for preventing an excessive loss of lubricant from the bearings.  The conical cutter is adapted with seal receiving grooves at its open end of the recess to receive two seals, with a circumferential seal gap located between the seals.  The outer seal is less rigid than the inner seal and when the circumferential seal gap is supplied with lubricant it bleeds past the outer seal to wash away drilling debris.  Lubricant can be supplied to the circumferential seal gap by lubricant carrying conduits which carry lubricant from separate reservoirs, or the inner seal could be a hydrodynamic seal which permits migration of some of the lubricant from the bearings into the circumferential seal gap but prevents contaminates and lubricant from the circumferential seal gap from traveling past the hydrodynamic seal back into the bearings.

Patent CA-2028711-A1 (CA)
Inventor: HECTOR LOUIS G
IPC: B21B3/00
Filed: 1990-10-29
Abstract: A method for rolling material between rotating rolls utilizing a lubricant, at least one of the rolls having an anistropic working surface that comprises a topography of smooth bearing areas spaced apart by at least one micron-size groove extending around and along the face of the roll in the general direction of rolling.  The groove receives and conducts lubricant freely therealong during the rolling process, i.e., as the material to be rolled is directed through the rotating rolls, and is compressed between the rolls, the smooth-bearing areas force lubricant from the areas to the location of the groove in the roll.  In this manner, the material is rolled under boundary lubrication conditions.

Title: Method and apparatus for separating biological substances and organic compounds in solution
Inventor: SOVA OTTO
IPC: G01N27/447
Filed: 1990-12-14
Abstract: ABSTRACT       A method and apparatus is described for separating materials  on  the  basis  of  differences  in  isoelectric points. In one aspect of the invention an electrochemical cell is provided which has a cell compartment having a plurality of interwaterproof compartments. Provided is a cell lid with a plurality of parallel panels which are narrower than the interwaterproof compartments. A pair of spaced electrodes are attached to the lid and insertable into the end compartments. When the lid is placed on the cell, with an appropriate amount of solution in the cell, a convection free current flow path is formed through the solution above the top edges of the compartments and along the sides of the cell between the gaps formed between the cell side walls and the edges of the narrower lid panels.          A  natural  pH  gradient  is  established  when  material containing the substance to be separated is dissolved in an appropriate  solvent,  thereby  eliminating  the  need  for expensive  carrier  ampholytes.  A  potential  is  applied between the electrodes which produces an electric field through the horizontal  flow path thereby acting  as  a driving force for moving charged species. When the charged species reaches a point in the pH gradient corresponding to the  pI  of  materials,  it  is  neutralized  and  remains stationary.
