Abstract: ABSTRACT OF THE DISCLOSURE:     A residual fuel derived from the distillation of petroleum crude is improved by heating the residual fuel to a temperature near its boiling point while maintaining the residual fuel in the liquid state; injecting water only, in the liquid state and at a pressure equal to or slightly greater than atmospheric pressure, into the heated liquid residual fuel, thereby causing a thermal shock and violent gasification and expansion of the residual fuel and water only; passing directly into a gas expansion chamber the gas formed by the thermal shock of the residual fuel and water only without having added thereto any other components or without undergoing any additional heating treatment; immediately thereafter continuously cooling the gas in a heat exchanger to form liquefied gas without having added thereto any other components or without undergoing any additional heating treatment; and withdrawing the liquefied gas as improved fuel free of impurities.  The fuel obtained by the process of the invention has improved characteristics, exceeding those of a residual fuel, thus facilitating control of environmental pollution and the economizing of fuel.

Abstract: ABSTRACT OF THE DISCLOSURE In production of sintered bodies of particulate metal, especially porous sintered bodies, from particles of metal having a refractory oxide coating, a minor proportion of a flux is mixed with the particulate metal before sintering to aid in removing oxide from surfaces of the metal par-ticles.  The particulate metal may be aluminum, with which there may be mixed a minor proportion of particles of an alloying element.  The flux may be a mixture of potassium fluoaluminate complexes; the residue of this flux, after sintering, provides a coating that aids in protecting the sintered article against corrosion.  Porous sintered bodies of the present invention are suitable for use as filters or the like.

Abstract: ABSTRACT   In EMI scanners it is desirable to substantially reduce the time required for measuring.  Therefore, it is necessary that the radiation source/ radiation detector system is not stopped and subsequently accelerated again for each measurement of group of measurements.  A system which continuously moves, preferably at a uniform speed, is very attractive.  The invention enables the evaluation of the output signals of the radiation detectors derived from such a continuously rotating system with continuously switched-on source.  To this end, the output signal of each radiation detector is conducted via a low-pass filter and applied to a sample-and-hold circuit having a sampling frequency which is about twice as high as the limit frequency of the low-pass filter.  Moreover, results can be obtained which are more accurate than those obtained with known scanners with discontinuous movement or a flashing radiation source.

Abstract: MODULAR HEAT EXCHANGER WITH PIVOTAL CORES                 A B S T R A C T            A heat exchanger is provided with pivotally mounted, angularly disposed, cooling modules or cores so as to increase the cooling capacity of the heat exchanger and, at the same time, to have a self-cleaning capability for the modules or cores.          The angular disposition of the modules or cores results in a larger effective frontal area to the heat exchanger thereby increasing the cooling capacity of the heat exchanger.  The angular orientation of adjacent modules or cores slightly compresses the oncoming air which provides an increased level of cooling for the cores.  Each module or core can be pivoted about an axis a sufficient amount such that the opposite surface of each module or core is swept by the on-coming air which passes around and through the modules or cores in a direction opposite to an initial pass of said air whereby the modules or cores are cleaned by the reverse flow of air.

Abstract: ABSTRACT OF THE DISCLOSURE             A circuit for controlling the reverse recovery current in a controlled rectifier.  The primary winding of a satur-able reactor is connected in series with the controlled rectifier.  A diode in parallel with a resistor is connected in circuit with the secondary winding of the saturable re-actor.  The diode is poled to provide a low impedance in the reactor secondary when current flows through the primary winding and through the forward direction of the controlled rectifier flowing through the primary winding of the re-actor causes current in the secondary winding to flow in the reverse direction of the diode.  The value of the re-sistor as reflected into the saturable reactor primary circuit limits the magnitude of the reverse recovery current.

Abstract: METHOD AND APPARATUS FOR LAYING AN   OIL FILLED CABLE AT DEPTHS BELOW      THE LAYING EQUIPMENT          ABSTRACT OF THE DISCLOSURE:  Method and apparatus for laying an oil filled, electric cable at great depths and under conditions whereby the weight of the oil may cause internal cable pressures which will rupture the cable.   In the method, the leading cable end is fed over a guide which is higher than the point at which the weight of the oil column between the guide and the cable source is equal to the normal oil pressure in the cable and is then fed downwardly but without exceeding an amount which would cause the oil column pressure after the guide to exceed safe limits for the cable.   The pres-sure on the oil at the cable source is then reduced pro-ducing a torricellian vacuum in the cable at or near the guide which is maintained at a value such that the weight of the oil in the vertical section of the cable does not exceed safe limits.   The apparatus includes the guide and pressure regulating and indicating devices at the cable oil source and the leading end of the cable.

Abstract: SECONDARY OXIDATION OF FLUID EFFLUENT  FROM PRIMARY OXIDATION OF META- OR             PARA-XYLENE                 ABSTRACT OF THE DISCLOSURE     Primary catalytic oxidation of m- or p-xylene with air in the presence of acetic acid solution of metal and bromine com-ponents of catalysis at temperatures from 130 to 250°C and at elevated pressure to maintain a liquid phase of the acetic acid solution produces a fluid oxidation effluent which is a suspen-sion of crystalline iso- or terephthalic acid in liquid acetic acid mother liquor containing, in addition to dissolved components of catalysis, some dissolved phthalic acid product and smaller amounts of both oxygen-containing precursors of such product and oxygen-containing aromatic co-products.     By the present inventive concept such fluid effluent is subjected to continuous secondary air oxidation under liquid phase conditions as it is being cooled to precipitate additional phthal-ic acid product.  Such secondary oxidation permits lowering the concentration of catalyst components in the primary oxidation, improves yield and quality of the phthalic acid product, signifi-cantly lowers acetic acid oxidation, and permits recycle to the primary oxidation of a major portion of solids content of acetic acid mother liquor as a source of components of catalysis.

Abstract: ABSTRACT     This invention, which I call an Operator Propelled Rotary Garden Tiller relates to a manually operated garden tillage tool, for light garden tillage and weed eradication. The usual, or conventional methods have been the use of horse drawn cultivators which often result in a trampling down of tender young plants, and is otherwise impractical in a smaller garden where space is limited and the rows are short. In re-cent years gasoline powered tillers have been placed on the market, while practical, the increasing cost of fossil fuels has been rising steadily, and are now becoming scarce.  Gas-oline powered tillers are inclined to be noisy, are air pol-luting, also bulky and rather heavy to handle and not suitable for closely spaced rows, and in such cases the old fashioned hoe must be resorted to. The purpose of the Operator Propelled Rotary Garden Tiller is to achieve, with the least possible expenditure of energy the maximum amount of tillage, that is, to soften up the soil to provide a mulching effect between the vegetable rows and to eradicate the weeds by the rotary action of the tines of the Operator Propelled Rotary Garden Tiller.
