Abstract: ABSTRACT OF THE DISCLOSURE In a continuous process for separating crude oil into two distinct fractions of high definition, crude oil is continuously introduced into a flow path having a portion relatively narrow in cross-section. Heat is supplied to the crude oil along the narrow cross-section portion of the flow path to volatilize one crude oil fraction thereby producing a mixture of a volatilized fraction and a residual liquid fraction. The rate at which the crude oil is introduced into the flow path, the narrow cross-section of the portion of the flow path and the heat supplied effect a high rate of volatilization, a high velocity of the mixture through the narrow cross-section portion of the flow path, and intimate contact between liquid and vapor fractions. After the residual liquid fraction and volatilized fraction mixture is discharged from the flow path, the volatilized fraction is allowed to separate rapidly and become isolated from the residual liquid fraction.

Abstract: A B S T R A C T      Method and apparatus for impact ionization of particles excited with isotopic selectivity, particularly for use in a system of uranium isotope separation and enrichment.  Efficient impact ionization is achieved by first selectively exciting vaporized particles of the desired isotope in a beam of finely tuned laser radiant energy.  The energies of the interacting photons are selected to produce a total energy shift during excitation which is slightly less than the ionization energy for the selected isotope.  The excited isotope will thus be raised to an excitation level only slightly below the ionization level.          This level is selected to permit efficient ionization, particle collisional ionization, between energetic particles in the uranium vapor environment and the highly excited particles of the desired isotope type.

Abstract: ABSTRACT       A holding arrangement is disclosed which can be employed to hold a winding enclosure which contains a low-temperature-cooled electric winding on which alternating external forces act, and which is fastened within a vacuum tank by means of tie rods.  In particular, the arrangement includes pre-tensioned tie rods which are arranged to unilaterally pull, via pressure posts, with force-transmitting contact the winding enclosure against the in-side walls of the vacuum tank.  More specifically, the tensioning force at room temperature is selected such that at low temperature a residual tension force remains which is always at least as large as the component of the external force opposing it.  With such a design for the holding arrangement no readjustment devices are necessary and the heat conduction effected thereby is relatively minor.

Abstract: ABSTRACT OF THE DISCLOSURE     A centrifugal fluid pump comprising a driven rotary assembly having at least two pumping stages operatively associated therewith and rotatable therewith as said rotary assembly is driven, each stage including a plurality of cir-cumferentially spaced hydraulic cylinders operatively inter-connected between a fluid supply tank that furnishes the respective hydraulic cylinders with the fluid and a pressure tank adapted to receive fluid under pressure from the respec-tive hydraulic cylinders as the rotary assembly is driven.  In operation, fluid is drawn into the hydraulic cylinders, and as the rotary assembly is driven the respective pistons of the hydraulic cylinders are driven radially outward causing fluid disposed on the outer sides thereof to be forced out-wardly from the hydraulic cylinders under the influence of the centrifugal force generated by the rotary assembly.  The pressure of the output fluid system is compounded by connect-ing the individual cylinders in series wherein the output of one cylinder is the input of an adjacently series connected cylinder.  During this process, fluid is pumped from a supply tank through respective hydraulic cylinders of the pumping system, into a fluid pressure tank, the pressure of the fluid in the pressure tank being substantially greater than the pressure of the fluid in the supply tank as a result of the centrifugal force applied against the fluid as the rotary assembly is driven.  It follows that the energy associated with the pressurized fluid can be harnessed by any suitable means, such as by pumping the pressurized fluid through a conventional hydraulic motor or using the pressurized fluid to drive some other fluid operated power generating mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE       A pulsimeter for indicating the average heart beat rate by counting the number of beats occurring during a predetermined period of time, comprising a pulse sensor means adapted for flat application against a part of a human body, and an electronic counter and display preferably arranged for being worn on a person's wrist.  The electronic counter and display comprise an input processing circuit which receives electrical pulses at the rate of the heart beats from the pulse sensor and which supplies to a counting circuit an electrical signal having n pulses for one heart beat, n being an integer factor of 60 greater than 1 and less than 60.  The counting circuit, also comprised within the electronic counting and display repeatedly counts the pulses from the input processing circuit during the predetermined period of time, the duration of which is 60/n seconds.  The counting  circuit is reset at the end of each such period of time, just after having transmitted its end counting value to memory circuit which supplies this value to the display during the whole next period of time.  A further circuit is provided for preventing more than n pulses from being delivered to the counting circuit during an interval between two con-secutive heart beats.  The displayed value is renewed every 60/n seconds, but its accuracy is the same as that which would be obtained by counting the heart beats every 60 seconds.

Abstract: METHOD FOR RECOVERING VISCOUS PETROLEUM               (D#74,601-F) ABSTRACT OF THE DISCLOSURE         Recovery of viscous petroleum from thick forma-tions is especially difficult because thermal fluids or solvents needed to mobilize the viscous petroleum tend to channel through high permeability streaks in the formation, thereby bypassing large portions of the petroleum saturated formation.  By forming or ensuring that there are naturally occurring high permeability strata in the upper portion and in the lower portion of the petroleum formation, and establishing separate communication means between the sur-face of the earth and the upper and lower high permeability strata, effective downward displacement may be achieved.          A heated fluid such as steam is injected into one well in fluid communication with the lower high permeability strata to pass horizontally through the high permeability strata to another well which is also in fluid communication with the lower high permeability  strata, sufficient to heat the lower high permeability zone to a temperature substantially above the ambient temperature of the forma-tion.  A solvent having a boiling point intermediate between the ambient temperature of the formation and the temperature to which the communication path is heated is injected into the heated communication path.  The solvent vaporizes and moves up into the formation immediately thereabove to dissolve into the viscous petroleum.  A gaseous substance is then injected into the upper high permeability strata to increase the pressure therein sufficiently to displace the mixture of viscous petroleum and solvent downward into the lower high permeability strata, wherein it is displaced horizontally to a remotely located well for recovery to the surface of the earth.
