Abstract: POOL FILTERING SYSTEM        Abstract of the Disclosure A pool filtering system is shown which will be de-described in connection with swimming pools although it should be understood that the same system may be used to refine industrial waters and for other installations such as killer whale and por-porpoise pools.  Dirty water from the pool passes into a stilling or surge chamber under the control of a flat valve, then passes through a large particle interceptor screen into a filter ele-ment chamber which has a plurality of generally vertically ex-tending filter elements, each having a coarse core covered by an outer layer of sufficiently fine mesh to retain an outer coating of diatomaceous silica, then through the filter elements in parallel to a manifold at the bottom of the tank which leads to the recycling pump and directs the clean water back to the pool.  A diatomaceous silica dry slurry feeder is installed above the filter tank.  A hypochlorinator is effective in the clean water line going back to the pool.  A heat exchanger may be mounted in the stilling chamber, if desired.  In a preferred form, each filter element comprises a vertical cylinder having an inner or core layer of silicon-bronze wire about 0.062 inches in diameter and between about 1/8 inch and 1/4 inch mesh, out-side of which is a layer of stainless steel flattened dutch weave wire between about 20 x 120 and 30 x 130 mesh welded to the inner layer.  These cylinders are between about 4 inches and 4-1/2 inches in diameter and between about 30 and 36 inches in length.  These elements are sufficiently strong to withstand a pressure differential of about 150 pounds per square inch.  An air reservoir is kept filled with compressed air under about 40 pounds per square inch and back-washing is accomplished by exploding or ramming the air from the air reservoir through the manifold system and up and out through the filter elements re-moving the spent diatomaceous silica which falls to the filter tank floor.  Preferably the top of the filter tank is open so that the condition of the filter elements may be inspected at all times and the filter elements may be washed with a hose if necessary to clean off the spent diatomaceous silica.

Abstract: ABSTRACT OF THE DISCLOSURE    The specification describes a method of producing ground alpha alumina trihydrate such that it is suitable for incorporation in a toothpaste.  The method includes the steps of grinding the substance to a mean particle diameter of less than 25 microns in the presence of a sufficient quantity of a potable organic acid or acid reacting salt to convert all free caustic soda on the surface of the particle to a sodium salt.  Such a method reduces the possibility of the combined particles and toothpaste corroding the aluminum tubes used to package the product.

Abstract: HIGH ENERGY ADAPTIVE IGNITION                     VIA DIGITAL CONTROL     Abstract A digital system controls ignition dwell for an inter-nal combustion engine.  Dwell time is maintained constant, thus assuring a constant high level ignition spark, over the entire active RPM range of the engine.  In addition, the system compensates for temperature and aging induced changes in the ignition components.    In operation, one sensor generates pulses representive of engine angular position while a second produces ignition pulses.  An angle counter stores the number of position pulses generated thereby creating a count representative of engine position.  A speed counter stores the number of position pulses generated for a clock interval, producing a count representative of engine speed.  Dwell time is initia-ted at a predetermined relationship between the counter outputs which assures a constant dwell time.  Feedback circuitry monitors current through the ignition coil and alters the clock interval to compensate for ignition com-ponent changes.

Abstract: ABSTRACT OF THE DISCLOSURE    A method for processing an oil-water emulsion to remove oily material therefrom comprising forming a mixture of the oil-water emulsion with liquid amine, in which oils of the emulsion are soluble and having an inverse critical solution point with water, at a temperature below the phase separation temperature of the amine and water so as to form a single liquid phase of amine, oil and water, separating said single liquid phase from any solids which may be contained in the emulsion, raising the temperature of the resulting single liquid phase above the critical solution temperature to effect Liquid phase separation whereby an amine phase containing substantially all of the oily material of the emulsion and a water phase containing substantially no oily material are formed, and then separating the liquid phases.  The amine phase is readily processed to recover oily matter therefrom and may be recycled for the processing of additional oil emulsion.  The filtration of solids from the single phase mixture is improved by addition of lime and/or filter aids.         The method is applicable to a wide range of oil-water emulsions, including oil-in-water and water-in-oil emul-ions, and finds particular tuility in the processing of waste emulsions which have been difficult to process with known methods.  Representative of these are the wool grease-in water emulsions resulting from wool scouring processes.

Abstract: HEAVY DUTY MOBILE PIPE STRAIGHTENING MACHINE OF RELATIVELY                 LIGHT-WEIGHT CONSTRUCTION     Abstract of the Disclosure A mobile pipe straightening machine is of relatively light-weight construction for increased transportability and finds particular application for straightening drill pipe in the field.  For minimizing the overall weight of the machine, a bed frame is provided in an elongate, trough-shaped, con-struction having first and second upstanding sides and a bottom member to define a bed space.  At least one drive roll is swivelly supported within the bed space, and first and second idler rolls are movably coupled to the bed frame in spaced relationship with the one drive roll.  Each idler roll is supported within a housing which in turn is supported within a dome-shaped support structure.  A bushing having a key slot and a key for the key slot is disposed between the dome-shaped support structure and the housing.  By keying the housing to the bushing and by providing a slot in the dome-shaped support structure, the bushing (and thus the housing and idler roll) can be rotated by control apparatus positioned laterally of the dome-shaped support structure rather than in a position overlying it, thereby reducing the height otherwise required.  Other features include:  (1) individual control of the upper idler rolls to allow roll straightening of hooked, upset ends of drill pipe;  (2) gag press straightening using separate gag press mechanisms; and (3) an individually actuable inspection mechanism which allows the pipe to be elevated from the drive rolls and rolled for visual inspection while still in the passage.
