Abstract: ABSTRACT         The invention relates to an improvement in a method of regenerating alkaline or alkaline earth metal oxides or hydroxides from solution particularly in delignification processes wherein a suitable transition metal such as ferric oxide is burnt with the solution to produce a mixed oxide that is subsequently treated in hot water to regenerate the alkaline or alkaline earth metal oxide or hydroxide and precipitate the transition metal oxide.  The improvement controls the presence of fines in the transition metal oxide to maintain these at an acceptable level in the fluidized bed combustion zone.  This is achieved by contacting the fines with spent liquor from a delignification process. The invention also provides for the pelletization of the fine material of the transition metal oxide and spent delignifica-tion liquor can be used as a binder in the formation of such pellets.

Abstract: ABSTRACT      Raw synthesis gases produced by the gasification of coal are treated to remove tars and oils by direct and indirect cooling to produce condensate streams which are treated under high pressure, viz 5 to 150 bar to rapidly separate out aqueous and organic phases.   Elevated temperatures may then be used to further minimise residence time.  The invention is further characterised in that the size of the separation vessels is of several orders of magnitude  smaller  than  used  in  conventional  ambient pressure separation procedures.

Abstract: ABSTRACT OF THE DISCLOSURE A method and system is disclosed for determining the location of a member of a class of individual transmitter-receiver units distributed throughout a defined facility.  A central station establishes a two-way communication channel with one or more relay stations and sends a coded message identifying a particular individual unit over the communication channel.  The relay stations respond to the message by sending out wake-up signals and radiant energy inquiry signals.  The individual unit identified in the inquiry signal responds with a radiant energy acknowledgment signal.  Embodiments of The invention disclose the use of infrared energy or ultrasonic energy for the radiant energy.  Ultrasonic signals are sent on a plurality of frequencies.  The relay stations send identification signals to the central station which identify the sending relay station and indicate whether an acknowledgment signal was received.  The central station determines the approximate location of the individual unit from the identification signals.          According to one feature of the invention, the relay stations are divided into groups in which each relay station of a group covers an area distinct from the areas covered by the remaining relay stations of the same group.  In this arrangement the central station can communicate with one group of relay stations at a time.

Abstract: ABSTRACT OF THE DISCLOSURE      The amount of gaseous flammable propellants such as dimethylether, difluoroethane, propane, butane, and the like can be increased to as high as from 30 to 50% by weight of a propellant composition by dissolving the normally gaseous propellant in the dispersed oil phase of an oil-in-water microemulsion. The aerosol pro-pellant compositions can be simply prepared by metering the ingredients other than the gaseous propellants into an aerosol dispenser, then adding the gaseous pro-pellant, under suitable pressure, into the aerosol dis-penser whereby simply shaking of the dispenser will result in the spontaneous formation of an oil-in-water microemulsion which is clear and stable and which can contain as much as about 50% by weight of the gaseous propellant without causing flaming when the composition is sprayed directly into a candle flame.

Abstract: HEAVY DUTY TUBE COUPLING                 ABSTRACT OF THE DISCLOSURE          A tube coupling with only a body and a threaded member is disclosed, the threaded member usually being a nut to overlie an outer sleeve and an inner sleeve unitary with the body.  These two sleeves define therebetween an annular groove to receive the end of the tube.  The method of tightening the nut onto the body provides that a generally conical cam surface on the nut interacts with a shallower taper conical cam follower surface on the outer sleeve to force this cam follower surface radially inwardly and longitudinally inwardly forming annular radially inward bulges on the outer and inner sleeves and on the tube trapped therebetween.  This interlocks the tube with the coupling, and provides a fluid seal at three different places, the inner wall of the tube, the outer wall of the tube, and the end of the tube at the bottom of the groove.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: FIBER OPTIC AMPLIFIER                Abstract of the Disclosure A pair of small diameter optical fibers are arranged in a side-by-side configuration, the first fiber providing a passive guide  for  pump  light,  and  the  second  fiber formed of a material, such as Nd:YAG which has amplifying properties  at the  signal  frequency.   The signal to be amplified propagates through the second fiber resulting in amplification of the signal.   The first fiber is pumped from one or both ends, utilizing a cone shaped rod which is optically coupled thereto.  A plurality of pump light sources  are  mounted  on  the  end  face  of  the  rod  to introduce collimated pump light into the large end of the cone shaped rod.   Total internal reflections on the cone walls  compress  the  pump  light  to  a  small,  fiber-size diameter end for propagation through the pump fiber and absorption by the active fiber.   The pump light sources are offset from the axis of the rod to excite high order modes  in  the pump fiber  to  enhance  absorption by the active fiber.  The pump light sources preferably comprise high power laser diodes and collimating microlenses.   By utilizing the cone-shaped rod  to couple light from the high power laser diodes to the pump fiber, high pump power densities    can   be   achieved,    yielding    increased amplification.
