Title: Optical transmission system with optical filter for providing protection against giant pulses
Inventor: VEITH GUSTAV
IPC: H04B10/291
Filed: 1993-06-09
Abstract: Abstract Optical Transmission System with Optical Filter for Providing Protection against Giant Pulses In optical transmission systems with fiber-optic ampli-fiers, an interruption of the fiber-optic link, e.g., due to fiber breakage, may cause a giant pulse to de-velop.            To prevent the giant pulse from propagating in the fiber-optic link, an optical filter (7) which blocks the wavelength region of the pulse is placed in the fiber-optic link. The wavelength of the optical sig-nal must be chosen to lie outside the wavelength re-gion of the maximum gain of the fiber-optic amplifier.            (Fig. 1)

Title: Method for making soft layered tissues
Inventor: EDWARDS STEVEN L
IPC: D21H17/36
Filed: 1993-06-14
Abstract: ABSTRACT OF THE DISCLOSURE           The formation of paper webs useful for facial tissue, bath tissue, paper towels or the like is substantially improved by forming the web in layers in which the second-formed layer has a consistency which is significantly less than the consistency of the first-formed layer.  The resulting improvement in formation provides a significant improvement in softness, particularly for wet-pressed tissues, while reducing the degree to which fibers protrude from the surface of the tissue.  This also reduces the tendency of the web to lint.

Title: Variable repetition rate picosecond laser
Inventor: UJAZDOWSKI RICHARD C
IPC: A61B18/20
Filed: 1994-01-05
Abstract: ABSTRACT A system for varying the pulse repetition rate of a pulsed  laser  beam   includes   a   computer  which   is electronically connected to the system's oscillator and regenerative amplifier.   Specifically,  the computer  is electronically connected to the oscillator to create a first  signal  which  is  indicative  of  a  first  pulse repetition rate for the laser beam,  as it is initially generated by the oscillator.  The computer then selectively divides the initial first pulse repetition rate by an integer to create a second signal which is indicative of a second pulse repetition rate.  The second repetition rate is  variable  according to  the  dividing  integer  and  is substantially lower than the first repetition rate.   The Pockels  cell  of  the  regenerative  amplifier  is  then activated by the computer with the second signal to admit pulses from the oscillator laser beam into the regenerative amplifier at the second pulse repetition rate.  Thus, the output laser beam from the regenerative amplifier comprises amplified pulses having a variable second pulse repetition rate.  The system may also include an attenuator which is controlled by the computer to establish the energy level of pulses in the output laser beam.

Title: Downhole activated process and apparatus for centralizing pipe in a wellbore
Inventor: WILSON DENNIS R
IPC: E21B43/11
Filed: 1992-09-11
Abstract: This invention relates to a downhole activated centralizer for centralizing pipes in a wellbore (10) for the exploration and production of hydrocarbons. The downhole activated centralizers (50) are carried within either the pipe casing (60) or the collars (90) or both and remain generally within the maximum outward profile of the pipe string so as not to interfere with the movement and placement of the pipe string in the wellbore. The pipe string may be rotated, reciprocated and circulated which enhances the ability of the installer to place the pipe string in a deviated or long reach wellbore. Once the pipe string is in place, the centralizers (50) may be deployed by one of several methods such that pistons mounted in openings in the peripheral wall of the pipe string move outwardly with sufficient force to move the pipe string away from the walls of the wellbore sufficient to form a complete annulus for cementing. Once the well is cemented, the plugs in the tubular pistons may be destroyed by one of several methods opening perforations to the formation.
