Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE         A method and means for determining the amount of stretch in a well logging cable is disclosed.  An optical fiber is run into a well with a logging cable and looped back to the surface.  A second optical fiber of nominal length is maintained on the surface.  A source of mono-chromatic light is passed through both fibers and recombined.  As the well logging tool is raised and lowered in the wellbore, the number of interference fringes passing a fixed point is determined.  The change in length of the optical fiber and, therefore, the cable will be equal to 1/2 the number of interference fringes passing a fixed point times the wavelength of light used. A precise determination of vertical location can then be made when this information is combined with information from a surface mounted odometer or encoder.  This infor-mation further allows a precise determination of interval bulk density or other formation parameters in which it is important to know the depth of a tool.

Pump signal pulses at a first optical wavelength are introduced into one end of the optical fiber.  Each pump pulse propagates through the loop formed in the fiber and then exits the fiber.   The pump signal pulses excite the molecules of the optical fiber to cause them to go to a higher, unstable energy level.  When the molecules return to a lower energy level, photons are emitted at a second optical frequency that has a wavelength that is shifted from the wavelength of the pump signal to form laser signal pulses.  The coupler is a multiplexing coupler that has a first coupling ratio at the  wavelength  of  the  pump  signal  and  has  a  second coupling ratio at the wavelength of the emitted optical signal.   The first coupling ratio is preferably close to zero and the second coupling ratio is greater than 0.5. The  laser  optical  signal  recirculates  in  the  loop  to stimulate  further  emission  of  optical  energy  at  the shifted wavelength in phase with the recirculating optical signal.   Each pump pulse is timed to enter the optical fiber loop  in  synchronism with the recirculating laser signal pulse so as to excite the fiber molecules so as to amplify the recirculating signal pulses.  The laser signal has  a  loop  transit  time related  to  the time  interval between pump pulses  such  that  a multiple  of  the  loop transit time is substantially equal to a multiple of the time interval.

Title: Soil displacement hammer
Inventor: KAYES ALLAN G
IPC: E21B7/06
Filed: 1987-08-26
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE         Soil displacement hammer for driving holes in the ground, comprising a substantially cylindrical body, a soil displacement head at a forward end of the body, a longitudinally reciprocable striking member housed within the body, and an anvil member within the body adjacent its forward end and adapted to receive hammer blows from the striking member to cause the body to be driven forward.  A retractable baffle member is mounted adjacent the forward end of the body and is movable between a retracted position in which it does not project from the body so that the soil displacement hammer describes a straight path in the ground, and an extended position in which it projects transversely from one side of the body to cause the soil displacement hammer to describe a curved path in the ground.  The invention also provides a method of tracking such a soil displacement hammer in the ground.

Title: Pattern processing
Inventor: LEANING ANTHONY R
IPC: G06K/
Filed: 1987-11-19
Granted: 1991-11-19
Abstract: ABSTRACT                  PATTERN PROCESSING     A two dimensional pattern such as a movement matrix generated in an inter-frame video coder is classified by forming  a  weighted  sum  modulo  x  of  a  set  of values representing  the  pattern.   The  values  may  be  pattern element values, or quantised representations of groups of elements.  The weighted sum is used to access a look-up table containing class identification words.  Optionally, motion  vectors  may  be  generated  by  comparing  class identification words derived from successive frames of a picture.

Title: Perimeter safety net system for multi-story buildings under construction
Inventor: BRICKMAN MORLEY
IPC: E04G21/32
Filed: 1988-01-27
Granted: 1991-07-30
Abstract: Abstract of the Disclosure A safety system for a multi-story building under construction includes parallel, vertical, stationary guide channels or tracks secured to the side of the building.  Vertically movable slide rails are slidably mounted within the guide channels.  Cantilever struts extend diagonally upwardly and outwardly from connections with the slide rails.  A safety net extends along the building with its outer edge anchored at the outer ends of the struts and with its inner edge anchored on the movable slide rails.  Vertical chains or cables are connected between the slide rails and a construction crane at the top of the building to lift the slide rails and net while in an extended condition to a new working position.  Brakes acting between the slide rails and guide channels automatically release to enable upward movement and automatically lock to hold the net in the new working position.

Title: Method and apparatus for high resolution ink jet printing
Inventor: HERTZ CARL H
IPC: B41J2/21
Filed: 1988-02-26
Granted: 1991-07-30
Abstract: ABSTRACT             An  ink  jet  printing method  is  disclosed,  wherein a  record is produced by applying varying amounts of ink on a plurality of pixel locations of a record medium, said method comprising the steps: a) generating an ink jet directed towards said record medium, said ink jet breaking up into a series of drops with a predetermined drop formation rate, b) applying  an  electric  charge  of  predetermined  magnitude  to selected drops, c) deflecting  each  charged drop as a  function of  its  charge to determine whether the drop travels  along a  recording path to reach said recording medium or is intercepted, d) producing relative transverse movement between said drop path and said recording medium, e) generating a first signal indicative of the drop formation rate, f) generating  a  second  signal  from  said  relative  movement,  the second signal being indicative that pixel position on the record medium is aligned with said drop path, g) deriving  a  density  value  for  the  aligned  pixel  position  in response to said second signal, h) generating a print pulse signal of predetermined length between leading and trailing edges in response to said derived density value and said first signal, said density value controlling the length and said first signal controlling the time of occurrence of the leading edge of said print pulse signal, i) controlling said charging step (b) by means of said print pulse signal.          To  reduce  the  graininess of  the image recorded by the jet, said first and second signals are synchronized to establish a predetermi-ned time relationship between the time at which said density value deriving step (g) occurs and the time when the leading edge of the print pulse occurs.
