Abstract: ABSTRACT OF THE DISCLOSURE           A cylindrical roller body having a surface texture incorporating a random pattern of cracks and lands in a select configuration for producing a nonhomogeneous and noncontinuous roller surface having improved fluid transfer characteristics.          The roller is mounted for rotation contiguous with a fluid supply and deposit area for transferring fluid therebetween.          The body of the roller is of structurally sound construction, often solid, being plated with a hard, durable material such as chrome.  The chrome is subjected to a specific plating, etching, and polishing process for producing an array of interconnected, shallow cracks and smooth, segrated lands thereupon.  The cracked cylindrical surface of the roller then presents a plurality of smooth, unconnected lands to fluids dispersed thereon.  Similarly, the interconnected crack pattern permits lateral flow of fluid between lands to reduce the surface tension and improve fluid transfer characteristics.  In this manner, the roller may be used in any number of applications in conjunction with fluid supply means and deposit area.  Like-wise, the roller can be used to transfer any fluid with more control, volumetric capacity and less surface tension dependency than conventional rollers of either greater smoothness or greater roughness.

Abstract: 48,040 ABSTRACT OF THE DISCLOSURE A method is disclosed for restoring a clay rich aquifer which has been solution mined with ammonium ions. Calcium carbonate is precipitated from a solution pumped through the aquifer by the addition of calcium oxide, cal-cium hydroxide, or a mixture thereof in quantities suffi-cient to raise the pH to at least about 9.5.  The precipi-tated calcium carbonate is separated from the solution and the  ammonium  ion  is then removed from the solution by standard techniques.  The solution is recycled through the aquifer and these steps are repeated until the bicarbonate ion concentration has been reduced to such an extent that the  addition of  at least one soluble salt of calcium, magnesium, or potassium to the solution does not result in precipitation of calcite underground, plugging the aqui-fer.  Recycling with the addition of the soluble salt is continued until the ammonium ion concentration is reduced to a desired level.  Finally, residual amounts of the salt are removed from the aquifer using standard techniques.

Abstract: GAS SEPARATION PROCESS     ABSTRACT OF THE DISCLOSURE         A crystallization process is disclosed for separating a crystallizable material and an excluded material which is at least partially excluded from the solid phase of the crys-tallizable material obtained upon freezing a liquid mixture of the materials.  The solid phase is formed and melted at spaced locations in a liquid mixture of the materials and, within the liquid mixture, internal solid and liquid flows are maintained in opposite directions to effect separation of the materials.  The solid phase is formed by evaporative cooling of the liquid mixture and melted by direct contact with a condensing vapor phase of the materials, each of these operations being performed substantially at the prevailing triple point locus conditions in the respective locations in the liquid mixture.

Abstract: MULTIBAND OPEN FRONT REFRIGERATED CASE WITH AIR DEFROST ABSTRACT OF THE DISCLOSURE      An open front refrigerated display case having mechanisms for establishing an inner refrigerated air band encircling the display portion of the ease and secondary air band also encircling the display portion and being positioned outside of the inner air band.  An inner air conduit passes around the cabinet of the display case and has an outlet opening at one end of the access opening in the front of the cabinet and an inlet opening at the other end of the front access opening in the cabinet.  A fan circulates air through this inner air conduit with the air leaving the outlet opening and being directed toward and received by the inlet opening of the conduit, thereby establishing an inner air band along with an inner air curtain across the access opening in the front of the cabinet.  An evaporator coil arranged within the inner air conduit serves to refrigerate the air passing along the inner air band during a refrigeration cycle of operation.  A secondary air conduit surrounds the inner air con-duit within the cabinet and during a refrigeration cycle carries air which is cooler than ambient air, but unrefrigerated.  A second fan is provided within this secondary air conduit for circulating air through the conduit and establishing secondary air band and secondary  curtain across the opening in the front of the cabinet.  During a defrost cycle of operation, the evaporator coil is turned off and the direction of air flow through the inner air conduit is reversed and unrefrigerated air is caused to pass through the inner air conduit, thereby serving to defrost that conduit.  During the defrost operation, the air flow through the secondary air conduit is either turned off or reversed in its flow direction.

Abstract: METHODS OF AND APPARATUS FOR DETERMINING ELECTRICAL CHARACTERISTICS OF TRANSMISSION LINES     Abstract of the Disclosure Apparatus is disclosed for automatically measuring accurately and rapidly alternating and direct voltages, resistance, and capacitance of a telephone line.  Direct voltages and relatively high resistances can be determined by filtering out 60 Hz a.c. signals and measuring line current with and without a voltage source connected in series with the line.  Capacitance is measured by charging the line from the voltage source, discharging the line into a plurality of integrators having different time constants, and sampling the output voltage of one of the integrators after a respective integral number of 60 Hz periods.  The integrator whose output voltage is sampled depends on the capacitance being measured.  The resultant measurement is corrected in respect of voltages on the line by performing a second integration without again charging the line, and the corrected result is modified to take into account the previously measured resistance of the line.     - i -

Abstract: RECIRCULATING BURNER            Abstract of the Disclosure An internally recirculating burner designed to operate at a low level of excess air without producing intolerable levels of particulate (smoke) and oxides of nitrogen using ambient or highly preheated atmospheric air as an oxidant.  The burner operates with a flame front outside of the burner in the com-bustion chamber with recirculation of furnace gas being pro-vided by the geometric configuration of the burner and the energy provided by the incoming combustion air.  A nozzle means for controlling the combustion air flow is disclosed con-centric with the burner center body.  The nozzle is comprised of a fixed ceramic nozzle plate having annularly arranged distribution holes and a nozzle plus also preferably of ceramic supported to open and close the annular flow passage between the nozzle and the burner center body as well as the annular flow distribution holes.  The air discharged through the nozzle flows along the surface of the center body creating a pressure depression at the point of discharge causing the furnace gas to flow from the furnace chamber to the passage formed by the burner barrel and the outside diameter of the recirculating sleeve.  The recirculated gas joins the incoming combustion air and flows parallel to the combustion air through the annular passage formed by the inside diameter of the recirculating sleeve and the outside diameter of the center body.  Some mixing of the combustion air and the recirculating gas occurs within the recirculating sleeve.  A flame holder forming a portion of the center body central tube at the discharge end of the burner creates eddies and provides for a flame holding zone in which the fuel can be injected and the flame sustained.  The flame thus formed extends into the combustion zone to the point at which the combustion reaction is completed.
