Title: Treatment of organic sulfur gases especially in kraft pulping systems and processes
Inventor: CHAMBLEE WAYNE
IPC: D21C11/00
Filed: 1992-02-07
Abstract: ABSTRACT      Gases containing water vapor and over 10% (e.g. about 15-80%) by weight organic sulfur compounds, such as off gases from a kraft or sulfite digester, black liquor evaporator, or apparatus for heating black liquor to reduce its viscosity, are converted into a gas stream comprising primarily hydrogen sulfide and methane.  Hydrogen can be added to the gas, and the gas in the presence of the added hydrogen may be passed past a hydrogen desulfurization catalyst (nickel or cobalt molybdenum).  Preferably the vast majority of the water vapor is removed before it is passed past the catalyst.  The hydrogen source may be provided by the gas itself, by passing a portion through a methane/steam reformer and separating hydrogen from the stream, to produce a gas containing primarily methane and carbon dioxide which is used for a combustion gas.  Hydrogen sulfide may be removed from the gas stream by passing it into contact with white or green liquor from kraft paper pulping processes. Alternatively, substochiometric combustion of at least some of the gas may be effected, and after soot removal the gas may be passed into contact with a dirty shift catalyst (an alumina catalyst containing oxides of cobalt and molybdenum) to produce a gas stream comprising primarily hydrogen sulfide and methane with some carbon dioxide.

Abstract: Abstract of the Disclosure A  system for recording fewer of the events that are caused either by Compton scatter photons or by gamma radiation interacting  with lead.  The  system locally determines the energy spectrum and fits the determined energy spectrum with a trial function composed of a photopeak  component  of known energy shape, but unknown magnitude and a Compton scatter component  having  a  theoretically  derived energy shape and an unknown magnitude for each pixel of the image.          The trial function  is  locally  fitted  to  the  measured  energy spectrum  to obtain the values of both the Compton Coefficient and the gamma radiation interacting with lead. This enables removal of Compton   contamination  and  also  the contamination  caused  by interaction of the gamma photons with lead components.

Title: Three laser optical disk drive system
Inventor: GOLDSMITH PAUL
IPC: G11B7/13
Filed: 1990-12-12
Abstract: An erasable optical disk drive system is disclosed which utilizes an electron trapping media (14) coated on the disk surface (10) to store data in the form of light energy and which utilizes three laser beams (50, 52, 54), each having a wavelength range distinct from each other as well as distinct from the wavelength range of the emission produced by the impingement of the read laser onto the electron trapping media. Data is written onto the disk, which is contained in a light-tight contamination-free environment, using a visible light laser beam. Data is read from the disk and the disk is erased by using a near infrared light laser beam (52). The focus and tracking functions of the disk drive system are accomplished by using a laser beam (54) having yet another range of wavelengths, which are greater than those of the visible light laser beam and those of the photon emission from the electron trapping optical memory media, but less than those of the read/erase laser.

Title: Controlling apparatus for continuous electrolytic ion water producing apparatus
Inventor: ARAI KAZUYOSHI
IPC: C02F1/461
Filed: 1992-09-21
Abstract: ABSTRACT OF THE DISCLOSURE       A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that the electrolyzing capacity of an electrolytic cell is kept fixed against a variation of the flow rate or the quality of water upon passage of water to always achieve optimization and stabilization of electrolytic ion water produced.   When water flows through the electrolytic cell,  it is energized by a power source circuit to electrolyte the water to obtain electrolytic ion water.   When a range change-over switch is manually operated,  a dc voltage of the power source circuit is controlled in response to the range change-over switch by a control unit and a switching regulator to produce an electrolyzing voltage corresponding to the operated position of the range change-over switch.  The water is thus electrolyzed with an electrolyzing strength of the electrolyzing voltage.  During such electrolyzing operation,  if the flow rate or the water temperature varies,  then the pulse width of the switching regulator is corrected to automatically adjust the electrolyzing strength in accordance with the varying condition thereby to always keep the electrolyzing capacity of the electrolytic cell fixed.

Abstract: SELF-ALIGNED PHASE-SHIFTING MASK                         Abstract A phase-shifting mask with self-aligned spacers of phase-shift material adjacent to the edges of the opaque mask  pattern  and  a  method  for  making the  same  is disclosed.   The  method  of  the  invention  deposits  a blanket layer of an appropriate phase-shift material over a transparent mask substrate having a patterned opaque layer followed by a removal step which forms the spacers. The mask is preferably comprised of a quartz substrate covered  with  a  patterned  chrome  layer  fabricated following the normal inspection and repair procedure.  A layer of phase-shift material is then blanket deposited. The thickness and index of refraction of the  phase-shift material is chosen to provide a phase-shift of 0.67 pi radians (120 degrees) to pi radians (180 degrees) in the completed  mask  which  is  the  range  of  phase-shift demonstrated to be effective.  The phase-shift layer is then blanket etched anisotropically in a Reactive Ion Etch (RIE) chamber, using the chrome and quartz as etch stops.   Following the  etch,  the  remaining phase-shift material forms a roughly quarter-cylinder cross-section shaped   spacer   pattern.    The   spacer   pattern   is self-aligned to the edges of the opaque mask pattern.

Title: Locking fiber cable casing
Inventor: SMITH THOMAS J
IPC: G02B6/44
Filed: 1992-12-23
Abstract: VIII.    ABSTRACT OF THE INVENTION A means for encasing fiber optical cable is presented which provides security, ease of installation and strength.  The casing is made of two identical halves which are manufactured from standard angle iron.  The two identical halves are joined together at the bottom by pinned hinges and at the top by off-set corresponding bolt holes and bolts.  The pinned hinges on the bottom of the two halves allow the halves to open up so that the casing can be placed around the optical fiber cable.  The two halves are then closed and clamped together to form a strong and permanent protection for the optical fiber cable, either by bolts or by the security lock.  One end of the main casing has a male projection with a chamfered outer edge with bolt notches which is inserted into the female end of a second length of casing.  The chamfered edge allows easy insertion of the male end into the female end.  The female end of the casing has bolt holes at the top and bottom.   When bolts are inserted through the bolt holes and the outer female end is tightened about the inner male projection, a firm and secure connection between the two lengths of casing is accomplished.  Alternatively, a security lock may be placed through the bolt holes to allow access to the cable only by authorized personnel.
