Title: Coloring a black and white signal using motion detection
Inventor: MARKLE WILSON
IPC: H04N9/43
Filed: 1987-12-01
Granted: 1991-10-22
Abstract: ROGERS, BERESKIN & PARR         Inventors:    Wilson Markle and Brian Hunt Title:     Coloring a Black and White Signal Using Motion Detection.     ABSTRACT OF THE INVENTION     A method and apparatus for coloring a black and white film.   The film is converted to video tape and the locations of edges of moving objects in frames of the video signal are used to develop a motion indicator key.   The motion indicator key is used to reduce noise in the video signal without smearing motion and is used to assign colors to the black and white signal.  For each scene of the black and white film, a color mask is produced for one frame.  The adjacent frame is then colored the same as the initial frame except  where  motion  is  indicated.     Where  motion  is indicated, a selected process assigns colors,  for example based on direction of movement or grey levels of adjacent pixels.   The new color mask thus produced is  used  as  a reference for coloring the next frame. In this way the whole film may be colored, scene by scene.  The color mask produced may then be combined with the black and white video signal to produce a colored video signal.

Granted: 1992-04-21
Abstract: PROCESS FOR AUTOMATIC FUSION WELDING OF RAILS     ABSTRACT OF THE DISCLOSURE     A process for automatic fusion welding of rails by a combination of submerged arc welding and electroslag welding, comprising a root run for welding a rail base by submerged arc welding and, without interruption of the welding, subsequent runs for welding the rail base and welding a region from a rail web to a rail head by electroslag welding; wherein, during all of the runs, a metal mold is mounted on an upper surface of the rail base and a metal shoe is mounted on the metal mold to prevent an outflow of molten slag and molten metal and, during all of the runs, welding is performed by using a DC welding transformer having constant potential charac-teristics, a filler-wire having a diameter of from 1.2 to 2.0 mm, and a fused-type flux.  The inventive process avoids the use of different fluxes and an alteration of welding machine conditions during the whole sequence of welding from the rail base through to the rail head.

Title: Permanent anchor for use with through tubing bridge plug
Inventor: TREVILLION WILLIAM L
IPC: E21B33/129
Filed: 1988-03-22
Granted: 1992-01-28
Abstract: PERMANENT ANCHOR FOR USE WITH THROUGH TUBING BRIDGE PLUG     Abstract of the Disclosure A through tubing bridge plug is disclosed.   In the preferred and illustrated embodiment, a central hollow tube having a passage therein supports the external parts. The central passage  terminates  top  and bottom with openings or passages.  At the top end, a sleeve valve mechanism originally pinned  in an open position is installed.  When the installation is completed, the sleeve valve is closed by a sequence of operations -to permanently close the flow path.   The device is set and anchored by applying a relative downward force to an external sleeve thereby deploying multiple link -toggle means to lock the device in location, additionally deploying a upwardly facing petal basket to receive a charge of sand and cement to form a plug,  and also deploying a centralizer.   The device is installed at a specified elevation by anchoring the toggle means to prevent movement, deploying the petal basket to hold sand and cement for curing,  locating the device in the casing by a centralizer, and bypassing fluid around the curing sand and cement through a central tubing opening below and above the uncurred materials.  The final step includes closing a sleeve valve means to prevent further flow through the device.

Title: Broadband optical detection of transient motion from a scattering surface
Inventor: MONCHALIN JEAN-PIERRE
IPC: G01B9/02
Filed: 1988-04-29
Granted: 1991-08-06
Abstract: Abstract of the Disclosure The  invention is concerned with a method and apparatus for optically detecting transient motion from a scattering surface.  A laser beam having a predetermined frequency  is  directed onto  such a  surface  to  thereby scatter the laser beam and produce a scattered laser beam defining  an  optical  wavefront  and  having  an  optical spectrum with a central peak at the laser frequency and a sideband on either side of the central peak.  The laser beam scattered by the surface is caused to interfere with a reference beam derived from the scattered laser beam and having  an  optical wavefront  substantially matching  the wavefront of the scattered beam and an optical spectrum with a single peak at the laser frequency and no side-bands, to obtain an   optical signal which is detected and converted into an electrical signal representative of the transient motion.  The optical detection technique accord-ing to the invention has a broad frequency bandwidth and a large étendue providing greater sensitivity of detection, and is  particularly useful  for detecting  small  surface deformations  of  a  material  or  workpiece  subjected  to ultrasonic energy.

Abstract: ABSTRACT            Conversion system for performing either an analog-to-digital A/D  conversion  associated with an  amplification  step or either a digital-to-analog D/A conversion associated with an attenuation  step.  The  system  includes  means  (115)  for receiving  a  input  digital  word  to  be  processed,  i.e. converted into analog and then attenuated, and means (165) for receiving an input analog value to be processed, i.e. amplified  for  scaling  purpose  and  then  converted  into digital. It also includes an digital-to-analog D/A converter (110), an attenuator (120) for attenuating the analog output of D/A converter (110), and a comparator (150) for comparing the value of the input analog value to be processed and the output of said attenuator  (120).   The processing of the D/A-attenuation process is performed by means of both D/A converter (110) and attenuator (120). In order to achieve the A/D-amplification process, the system further includes means (140)  for generating a sequence of digital words to the D/A converter (110), and means (220) for storing among this  sequence,  the  digital  value  that  minimizes  the difference between both  input of comparator  (150).  This digital   value   is   extracted  as   being   the   digital representation of the amplified analog input value. Since both  A/D-amplification  and  D/A-attenuation  processings involve the same physical components, both processing have transfer  function  exactly  inverse  of  one  another.  The typical  use  of  this  circuit  is in  echo  cancellation technique.            Fig. 1
