Abstract: Abstract of the Disclosure Fluorinated l-hydroxy-2-naphthamide couplers which are N-substituted with a lower alkylphenoxybutyl ballasting group are disclosed as well as compositions and photographic elements containing these couplers in coupler solvent particles.  The coupler solvent particles are comprised of a combination of a coupler solvent and the coupler capable of permitting the formation of a micro-crystalline dye.  Surprisingly these microcrystalline dyes exhibit a broadened absorption characteristic in the 750 to 850 nm region of the spectrum.  Dye images having such absorption characteristics are particularly suited to forming integral infrared absorbing sound tracks in photo-graphic elements, such as motion picture projection films.

Granted: 1981-08-04
Abstract: Abstract of the Disclosure A continuous process for the selective removal of hydrogen sulfide from a hot gas stream containing hydrogen sulfide by contacting the effluent with particulate nickel or nickel oxide at a temperature whereby the hydrogen sulfide will react to form surface coatings of a sulfur/nickel liquid phase.  The temperature of the system is maintained in a range so that the sulfur-containing liquid phase continuously drains off of the particulate solid phase exposing fresh surface areas for further reaction.  The liquid phase separates from the solid phase, is removed from the reaction zone and collected for processing for recovery of nickel.

Title: Timing value dwell reversal protection for glassware  forming machine electronic controls
Inventor: ZABOR ERIC R
IPC: C03B9/41
Filed: 1979-01-04
Granted: 1982-06-15
Abstract: ABSTRACT       A control system for a glassware forming machine which has a plurality of individual machine sections each capable of individually forming glassware articles.  Each individual section includes a plurality of forming means responsive to control signals generated by an associated section control means for forming articles of glassware in a cyclic series of predetermined forming steps.  The relative position of each forming step in one of the cycles is defined by "on" and "off" timing values stores in the section control means for each forming means to be utilized in the forming step.  The section control means is responsive to the timing values for generating "on" and "off" control signals to respectively actuate and deactuate the associated forming means.  The time between the "on" and "off" timing values for each of the forming means is known as the dwell time and this time can be changed utilizing a manual control to shift one or both of the timing values.  During such a change, the section control means automatically prevents a dwell reversal by prohibiting a change which would move one of the timing values past the other one of the timing values.

Abstract: ABSTRACT OF THE DISCLOSURE     A coal slagging gasifier is improved by providing an improved slag removal orifice.  The orifice is located centrally within the hearth of a gasifier of the type in which hot burner gases are directed up through the orifice to retain the slag in molten condition on the hearth and in which the slag is periodically discharged through the slag removal orifice.  The slag removal orifice is formed as a substantially vertical passageway through the removable slag tap member which comprises a solid cast mass of high thermal conductivity metal having an integrally formed metal tube for circulating liquid coolant through the cast mass.          The upper tundish surface of the slag tap member slopes downwardly and inwardly and merges with the slag removal orifice.  The coolant tube is capable of retaining its shape without any appreciable distortion during the casting of the surrounding metal mass, extends through the cast mass and forms a coolant conduit adjacent to the tundish surface and to the surface of the orifice passageway and spaced from these surfaces a distance of 0.25 to 1.5 inches.  The  ends of the tube project out from the mass to provide a coolant inlet and outlet.  In operation, coolant is circulated through the tube such that the surfaces of the cast mass in direct contact with slag and burner gases are maintained at a temperature of from 50°C. to 400°C.

Abstract: ABSTRACT OF THE DISCLOSURE An error-correcting system is disclosed, which system is located between a memory and a central processing unit. The system is comprised of a relief bit memory, an ECC (Error Correction Code) logic circuit, a switching circuit and a correction controlling circuit. The ECC logic circuit detects the occurrence of a soft error and a hard error. When a hard error occurs in the memory, the defective memory cell thereof is switched to the relief bit memory. Accordingly, data to be written into the memory or the relief bit memory is switched by means of the switching circuit. Similarly, data to be read from the memory or the relief bit memory is also switched by the switching circuit. The data to be stored in the relief bit memory is validated by means of the ECC logic circuit and the switching circuit. Further, the (n+1) -bit soft and hard errors are reduced to n-bit soft and hard errors by means of the ECC logic circuit and the switching circuit.

Abstract: MULTILINE RISER SUPPORT AND CONNECTION             SYSTEM AND METHOD FOR SUBSEA WELL            ABSTRACT      A support and connecting system for a multiline riser which joins a floating platform to a subsea well is shown including a support housing which mounts upon the floating platform for disconnectably mounting a termination housing to  which  a  plurality  of  lines  are  connected.    The termination housing is also connected to the platform by a cable tensioning system which adjusts the tension within its connecting cables.  A termination head fits within the termination  housing  and  connects,  through  a  termination riser adapter, to the uppermost riser of a riser run that communicates between the platform and the subsea well.  The arrangement permits the riser  run to engage the floating platform during assembly and recovery of the risers.   In the  event! of  a  storm  or  other  need  for  emergency disconnection,  the  riser  run may  be  withdrawn  from  the termination  housing  and  hung off  or  recoved  without disconnecting the lines.  During production operations, the riser  run  floats  free of the platform connected  thereto solely by the multilines and  tensioning  system.   During drilling operations,  a telescoping joint connects the termination housing to the support housing.
