Abstract: SIMPLIFIED DYNAMIC ASSOCIATIVE CELL                      ABSTRACT    This specification describes an associative memory cell capable of performing logic functions.  The cell comprises two transistors with their collectors connected to an output line; with their emitters either left floating or connected to an input line carrying either true or complement of one variable; and with their bases either connected to an input line carrying the true or complement of a second variable or to the output line which is main-tained at a fixed potential.  This permits the performing of sixteen different logic functions of the two input variables by the cell.

Abstract: HELICOPTER TYPE AIRCRAFT WITH    GROUND EFFECT STRUCTURE        ABSTRACT OF THE DISCLOSURE      The aircraft in the nature of a helicopter is movable in a vertical direction when being raised from the ground or landing thereon.  The body of the aircraft is toroidal in form, that is the say, the shape of a doughnut having a central aperture.  The central aper-ture has a jet engine mounted therein providing a downward thrust on the centerline of the body aperture.  A substantial ground effect is obtained by the use of panels which are movable from the underface of the body to a vertical position enclosing the central area therebeneath. Supports extend upwardly and outwardly from the central jet engine having a pivotally mounted turbine on each of the upper ends, the extend-ing shafts from which have an elongated helicopter type of propeller mounted thereon.  A ram, or other type of motor, is employed for tilting one or both of the turbines and propellers from an angular position to a position of greater tilt to provide a forward movement to the body.           The jet engine has a chamber which received gas from its pressure chamber and passes it through conduits upwardly through the trunnions of the turbines for driving the turbine motors in opposite directions of rotation to balance the torque from the propellers.  A ring about the jet engine is movable downwardly by rams to cam hinge plates upwardly for closing or reducing the size of the aperture at the engine end.  This provides substantially more pressure to the turbines permitting the propellers driven thereby to take over substantially the entire suspended weight of the body after it has been raised a substantial distance from the ground and the jet engine lift effect has been substan-tially reduced.  The ground effect panels are moved into recesses at the underface of the body and the turbines and propellers are tilted to direct air through the central opening of the body.  While the tilting of the pro-pellers produces forward movement to the body, the direction of flight is more accurately controlled by a rudder in the air stream from the tilted propeller.

Abstract: Abstract of the Disclosure The invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particulate fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins.  The titanate-phosphite adducts serve to reduce the viscosity of filled epoxy resins, thereby permitting higher filler loading, to enhance the tinctorial power of pigments, and to render casting resins water-extendible.          The titanate-phosphite adducts are the reaction products of one mole of a compound having the formula (RO)4Ti and two moles of di-substituted hydrogen phosphite, (R'O)2P(O)H, where R and R' are monovalent alkyl, alkenyl, aryl, aralkyl or alkaryl.  Both R and R' may be alkoxy, aroxy, bromo or chloro-substituted derivatives of the aforesaid groups.  R may have form 1 to 18 carbon atoms, preferably 3 to 12, except where the titanates are used for water-extension, where R is preferably 6 to 12. R' may be from 3 to 18, preferably from 6 to 14.

Abstract: NMR FIELD FREQUENCY LOCK SYSTEM     Abstract of the Disclosure An NMR (nuclear magnetic resonance) spectrometer has a permanent magnet provided with a field coil.  A lock system cyclically pulses a deuterium lock sample to produce a FID          (free induction decay) signal that is analyzed by measuring the time interval during which the FID signal crosses the zero axis a predetermined number of times.  The measured interval is compared to a predetermined interval or set point, and the current through the field coil is adjusted in the direction tending to correct the field strength so as to maintain the measured interval equal to the preset interval.          Such measurement, comparison and adjustment are done several times each second.  When the sample is removed, the lock system retains the last field setting achieved with the sample.

Abstract: ABSTRACT OF THE DISCLOSURE                    Purified albumin is recovered from human blood plasma without denaturing the globulins present therein, by mixing the blood plasma with 150 to 300 g polyethylene glycol (PEG) per liter of liquid mixture and adjusting the mixture to a pH of 6 to 7 for precipitating fibrinogen and globulins while forming a supernatant containing albumin. The supernatant is then separated from the formed precipitate, and the pH of the super-natant is adjusted to a pH of 4.5 to 5.3 for precipitating albumin. The albumin is redissolved with entrained PEG in an aqueous medium, the resulting albumin solution is subjected to thermocoagulation at 50 to 65°C and a pH of 4.6 to 5.0 in the presence of a stabilizing amount of caprylic acid, and the purified albumin is isolated from the solution by precipitation.        This process enables to obtain a high yield of albumin with a high degree of purity, suitable for intravenous injection.
