Abstract: ABSTRACT OF THE DISCLOSURE DEVICE FOR COMPENSATING THE LACK OF BALANCE OF A DEVIATING MIRROR BELONGING TO AN OPTICAL SYSTEM FOR ILLUMINATING A DATA MEDIUM     The present invention relates to a device making it possible to eliminate the lack of balance of the deviating mirror of an optical system for illuminating a data medium or support, when said mirror is subject to a rapid displacement.      The lack of balance is cancelled out by means of photodetector means receiving the light reflected by a reflecting element positioned around the objective of the optical system for illuminating medium. Control means then make it possible to control the position of the mirror.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is provided herein for pulverized ignition fuel for igniting a pulverized-fuel annular burner flame having an internal back flow region, with the ignition energy for the annular burner flame being introduced centrally into the interior of the back flow region of the annular burner flame.  The first step involves supplying the burner with a pulverized fuel/ carrier air mixture from a pulverizing plant via a primary fuel conduit.  The next step involves providing a pilot light for furnishing the ignition energy, the pilot light being operated with pulverized ignition fuel having at least one of the characteristics of coarseness and consistency different from the same characteristics of the primary fuel.  The next step involves withdrawing the pulverized ignition fuel for the pilot light from the primary fuel conduit through the opening of a withdrawal device which is capable of being shut off. The next stop involves processing the withdrawn pulverized ignition fuel prior to supplying it to the pilot light.  The final step involves directing the withdrawal opening of the withdrawal device counter to the flow in said primary fuel conduit.  Thus, the quantity of the ignition fuel/carrier air mixture withdrawn by means of the withdrawal device can be regulated in conformity with the output of the pulverizing plant.

Abstract: ABSTRACT   A Faraday rotator comprises a ferrimagnetic garnet film epitaxially grown on a non-magnetic garnet substrate and a magnet for inducing a magnetic field in the film to rotate the plane of polarization of a light beam applied to the film.  The substrate and the film are made of a material such that the absolute value of the difference between the lattice constant of the substrate and that of the film is less than or equal to 0.001 angstrom units.  This low value of mismatch has the effect of obtaining isolation of at least 25 dB in the rotator.  Techniques for reducing surface roughness and inappropriate light incidence to the filling two further causes of poor isolation properties, are also described.

Abstract: METHOD AND APPARATUS FOR TREATING NATURAL       GAS FROM GAS WELLS FOR SAFE TRANSPORTATION                 IN PRESSURE VESSELS               ABSTRACT OF THE DISCLOSURE           A system for treating natural gas from a gas source, such as a gas well, to make it suitable for safe transport in high tensile strength pressure vessels at pressures in excess of 2000 psi.  The system comprises suitable pipes and valves for taking gas from a gas well.          A separator is provided for removing free liquids from the gas fed thereto from the gas well to provide a sub-stantially liquid-free gas.  A compressor compresses the substantially liquid-free gas to a higher pressure to reduce the volume of the gas for storage in the pressure vessels.  A cooler is further provided to reduce the volume of gas and to recondition the gas for dehydration.  A dehydrator substantially lowers the water vapor content in the gas to a concentration of less than 0.1 lb H2O/mmscf of gas to prevent the formation of free water within the pressure vessels when transporting and unloading the gas and which water would cause internal corrosion and failure of the pressure vessels.  Pipes and valves are also provided for loading the pressurized dehydrated gas in the vessels.
