Abstract: VAPOR RECOVERY NOZZLE Abstract of the Disclosure.  A vapor recovery nozzle for dispensing fuel, such as gasoline, that can be latched to the filler neck of a tank to be filled.  An articulated seal is provided that sealingly engages the filler neck and, when so engaged, forces a piston relatively toward the nozzle to open the flow passageway through the nozzle for the vapors.  A valve is provided that is actuated by the piston which, when the nozzle is not in the filler neck, closes to prevent the escape of any vapors that might be contained in the vapor recovery system.  Furthermore, the piston carries a valve operating means that functions in conjunction with a flow valve that is located in a conduit ex-tending through the nozzle.  This conduit is utilized to sense when the liquid level in the tank rises above the end of the conduit extending from the nozzle to automatically shut off the nozzle and prevent flow of fuel therefrom.  The arrangement of the nozzle is such that the vapor recovery passageway extending therethrough is sealed to prevent the entrance of air or other vapor into the system except as may come from the fuel tank.             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE       A generally hollow packing element or body of relatively high surface area having a plurality of open end tubes situated within and connected to one another. At least two of the tubes have walls with or without openings therein extending around and inclined at an angle to a central axis of the element. A plural-ity of ribs are angularly spaced around the axis and include ribs extending between the walls, ribs projecting from and beyond an end of an outer tube and ribs extending from the central axis which divide the body into a plurality of sectors and chambers. Whether elements are stacked or randomly dumped into a vessel the majority of the surface area of the elements are inclined and neither parallel nor normal to the axis of the element or the vessel. Hence, liquid treated in a biological trickling filter vessel packed with the elements must undergo a horizontal dis-placement which tends to correct any initial maldistribution thereof, increase the length of the path of liquid flow and con-tact time between the liquid and biomass and reduce the velocity of the liquid allowing biomass to become more easily established. Also a continuous slower flow of liquid is maintained across the inclined surface which eliminates stagnation, loss of efficiency, and exerts a scouring action tending to wash away dead biomass to keep activity high and limits the growth of the biomass which might tend to plug the openings in the elements.

Abstract: ABSTRACT OF THE DISCLOSURE                  This is  an improved  process of manu-facturing N-acyl derivatives of glycines ?-substituted by radicals with an aromatic   nature  by condensation of the addition product of glyoxylic acid and an amide, with an aromatic compound.  In a first stage, the reaction is carried out at low temperature, in a concentrated sulfuric medium, of an aliphatic nitrile of the formula R-C?N in which R is a radical selected from the group of substituted and unsubsti-tuted, saturated and unsaturated alkyl radicals, with a con-centrated aqueous solution of glyoxylic acid.  Then in a second stage, the mixture obtained is condensed also at low temperature with a compound of aromatic  nature  not inclu-ding a hydroxyl group and having at least one substitutable free hydrogen, and the resulting product is collected.  The concentrated sulfuric acid may be supplemented with acetic acid during the second stage.  A surface active agent may be also added in this stage.  The products are valuable inter-mediates for the preparation of semi-synthetic penicillins.

Abstract: Abstract of the Disclosure The disclosure of the present applicatîon relates to an improved method of open-arc welding.  According to the present method, the outer shield of a double-shield welding system consists of a stream of gas formed in a shield concentric with the inner shield.  This method is distinguished by the fact that atmospheric air may be used as the outer shield gas because the outer-shield velocity is so regulated as to prevent the air from being drawn into the weld area. In an alternate embodiment of the same method, the outer-shield gas flow is in a direction opposite that of the inner shield.  In this alter-nate embodiment, in which air is drawn into the welding cup, the velocity at the outer cup is in a range predominantly above the velocity at the inner cup.  In the embodiment in which the gas in the outer shield flows in the same direction as that in the inner shield, the outer-shield gas velocity is in a range more nearly approximating the inner-shield gas velocity.

Abstract: AN ELECTRONICALLY ALTERABLE NON-LATCHING JOSEPHSON         AND, OR, NAND, NOR LOGIC CIRCUIT                         Abstract of the Disclosure An electronically alterable logic circuit is disclosed which provides different logical outputs which are a function of con-trol signals applied to the circuit.  More specifically, a non-latching Josephson junction circuit is provided which is capable of providing true and complementary outputs at a pair of output terminals when at least one pair of a plurality of pairs of fixed biases are applied to a plurality of serially arranged Josephson junction devices.  The Josephson devices are arranged so that a true output can be obtained from an output circuit which shunts a pair of Josephson devices while the com-plement of the true output can be obtained at an output circuit which shunts an appropriately biased Josephson junction which is disposed in series with the above mentioned pair of Josephson junctions.  The comple-mentary output is achieved by utilizing a portion of the output circuit, which shunts the pair of Josephson junctions as a control line for the single Josephson junction in series with the pair of Josephson junctions. The current through the control line portion, when present, opposes a bias current setting up a situation such that when current flows in the output representative of a true output, no current flows in the output repre-sentative of a complementary signal and vice versa.  In addition to achieving true and complementary outputs which can be characterized as AND, NAND, OR and NOR outputs, it has been recognized that these same outputs can be attained at the complementary output by simply applying binary combinations of biases to the two bias lines associated with the logic circuit.  In other words, if predetermined biases are applied, the input signals can, for example, be AND'ed while, for another set of biases for the same input signals, the input signals can be OR'd.  Thus, for one period of time with a given set of biases, the circuit disclosed is capable of applying one logic function to the input signals while, in a second time period, the same circuit, by simply changing the biases, is capable of applying a different logic function to the same or different input signals.  To the extent that a large number of such circuits is utilized in a data processor, the specific function of each circuit can be programmed from time period to time period so that the same circuitry can be configured in a different way and indeed appear as if an entirely different machine were available.  The ability to electronically alter the logic function of a circuit has applications in the data secrecy and data scrambling areas.
