Abstract: METHOD OF FABRICATING OPTICAL FIBER PREFORMS                ABSTRACT OF THE DISCLOSURE An improved method for  fabricating  an optical fiber  preform by the vapor phase  axial  deposition (VAD)  method,  comprising forming core and cladding soots at the same time by the use of core and cladding burners.  The improvement is that the cladding burner is designed so that at least one of the outlets for a feed material gas, a fuel gas, an auxiliary fuel gas, and  an  inert  gas  is  composed  of  a  plurality  of openings.   In this improved method,  the temperature distribution from the boundary of the core soot to the periphery of the cladding soot is made smooth,  and thus the cladding soot is prevented from cracking.

Abstract: WELL COMPLETION METHOD AND APPARATUS                       ABSTRACT      A pipe  string with a valve,  pressure  responsive means, packer, firing mechanism and perforating gun are suspended within a well to complete the well.  The packer is set to form an upper and lower annulus, and the valve and pressure responsive means are disposed above the packer in the upper annulus.  A signal transmission means extends from the pressure responsive means to the firing mechanism in the lower annulus.  The valve is ini-tially closed to prevent fluid flow through the flow bore of the pipe string.  The upper annulus is pressurized to open the valve and create a pressure differential across the pressure responsive means.  The pressure responsive means then transmits a signal through the signal transmission means to the firing mechanism to actuate the fixing mechanism and detonate the perforating gun.          Hydrocarbons from the formation then flow through the perfora-tions and up the flow bore of the pipe string to the surface.

Abstract: ABSTRACT OF THE DISCLOSURE A cold storage cell in the form of a hollow plate or shell con-structed of material having high heat conductivity and filled with a eutectic solution having a freezing point substantially below the freezing point of water in order to enable the latent heat of fusion of the freezable solution to be utilized at a lower temperature for cooling and freezing of various food items or non-food items.  The cold storage cell is closed and filled with a solution of ethylene glycol and water propylene glycol and water or a brine solution in which the ratio of the glycol to water may be varied depending upon the freezing temperature desired.  The cold storage cells are used in various types of refrigeration systems such as the type employing an air blast to cool the cold storage cells from ambient temperature to a temperature where the freezable solution is frozen which cooling process can take a relatively long period of time depending upon the air temperature, the amount of freezable liquid solution in the cells, the refrigeration system capacity, the number of the cells and the like so that all of the cells will be cooled sufficiently to remove the latent heat of fusion of the freezable solution after which the refrigeration system is ready for loading with items to be cooled.  As the items or products are loaded into the refrigeration machine, the warmer items or products will be cooled by the cells as the refrigeration stored in the cells is released with the refrigeration system continuing to operate at its capacity which may be at a capacity less than the refrigeration released by the cells or at a capacity sufficient to replace the refrigeration released by the cells to the items or products.

Abstract: IMPROVED PROCESS FOR FORMING THERMALLY STABLE THERMOTROPIC LIQUID CRYSTALLINE POLYESTER OF PREDETERMINED CHAIN LENGTH               Abstract of the Disclosure An improved polymerization process is provided for the formation of a polyester which is capable of forming an anisotropic melt phase and which optionally may include amide linkages.  An approximately 0.4 to 3 percent molar excess of aromatic dicarboxylic acid monomer (e.g. tereph-thalic acid) and/or an esterified derivative thereof is provided in the polymerization zone during the polymerization reaction.  Such monomer imparts dicarboxyaryl units to the interior of the resulting polymer chains and causes the polymer chains to terminate in carboxylic acid end groups and/or an esterified derivative thereof wherein the polymer chains achieve a predetermined average chain length through the depletion of other monomers present in the polymerization zone.  The resulting polyester unlike the usual product of the prior art is substantially incapable of additional chain growth upon subsequent heating and accordingly may be relied upon to maintain a substantially constant viscosity during melt processing regardless of the duration of heating.

Abstract: ABSTRACT OF THE INVENTION          A process for treating wood substrate, including textured hardboard having surface irregularities consisting of high ridge areas protruding above the surface, with a low viscosity aqueous coating to produce a coated article having substantially uniform film thickness.  A substantially uniform film can be obtained by preheating the substrate (about 250 to 400°F), flooding the surface with the aqueous coating, partially dewatering and affixing the coating to the surface by coalescence and removing the excess coating.  It is necessary to critically control the substrate temperature and time in which the coating remains in contact with the heated substrate before the excess coating is removed using an air knife.

Abstract: Abstract:    In a roadway surface reconditioning apparatus, for example, a scarifier for use with an asphalt or like bituminous roadway surface, a number of heaters of the luminous wall type are employed to direct large quantities of radiant heat downwardly towards the surface for softening it while travelling along the roadway.  These heaters consist basically of porous fire bricks through which an air/propane mixture passes and on the surface of which it burns.  Each heater also has porous side walls that project closer to the roadway surface than the main bricks and are supplied with air for forming a downward curtain of air to inhibit sideways escape of heat from the region beneath the heater.  The heaters are assembled in banks that are spaced apart from each other in the direction of travel.  This spacing can be adjusted.  Each pair of adjacent banks is bridged by heat deflectors that help to provide heat soak areas between the heater banks.          The apparatus also includes a novel scarifying assembly with increased adjustability of the scarifying depth of the teeth.

The time duration of the electrical pulse is control-led to be sufficiently long to assure proper opera-tion of the solenoid and is determined by a timing circuit coupled  to the source of  operating voltage for  the  solenoid.    If  the  operating  voltage  de-creases, the time required to charge the timing cir-cuit increases, increasing the duration of the elec-trical pulse of the solenoid to assure proper opera-tion under low voltage conditions.
