Abstract: ABSTRACT OF THE DISCLOSURE     In a procedure for selectively separating the isotopes of a multi-isotopic element by forming a gas of isotopic com-pounds of the element, selectively exciting the molecules of one isotopic compound by application of laser radiation thereto, and separating the excited molecules from the other components of the gas by physical or chemical means, the efficiency of the separation is improved by passing the gas, prior to laser excitation, through a nozzle to cause it to undergo adiabatic expansion to form an undercooled gas stream, and applying the laser radiation to the gas stream.

Abstract: GAME PLAYING STRUCTURE, PARTICULARLY SOCCER GAME STRUCTURE                        ABSTRACT OF THE DISCLOSURE A game playing structure, particularly a soccer game where the ball, disposed on a playing field at a given distance from a player figure, is thrown away by the movement of a throwing portion of the player figure, the movement of this part being obtained through mechanical means operated by a person taking part in the game.  The throwing portion of the player figure may be a leg swingable under the action of a biasing spring.  The figure is movable parallel to the surface of the playing field through the mechanical means.  An obstacle is arranged on the surface of the playing field in the path of motion of the throwing portion, which obstacle during the figure movement initially holds back the throwing portion and rotates the same against the biasing spring and then releases it as the figure moves further, thus throwing the ball away on the playing field.

Abstract: ABSTRACT OF THE DISCLOSURE            A quick release centrifugal clutch construction having a driven member rotatably mounted on a shaft and a drive member rotatable with the shaft and axially engageable with the driven member.  The drive member includes a rotor mounted on the shaft for rotation with the shaft.  A cartridge is axially slidably mounted on the shaft and has a frictional coupling surface for en-gagement with the driven member, and has a preloaded disc spring mounted thereon.  A drive block also is axially slidably mounted on the rotor and is adapted to engage the cartridge to further load the disc spring and to drivingly connect the cartridge with the driven member.  A plurality of individual pairs of links are mount-ed circumferentially spaced on the rotor and are movable in radial directions between retracted and extended positions.  The inner ends of each of the link pairs are pivotally joined by a pivot pin with the outer link ends being pivotally connected to the drive block and rotor member respectively.  Coiled tension springs main-tain the link pairs in retracted position, whereby the pivotal con-nections of the inner link ends are located radially inwardly of imaginary lines extending in a generally axial direction between the pivot connections of the outer ends of the links.  The link inner ends move radially outwardly under the influence of centri-fugal force and overcome the tension of the coiled spring when the shaft reaches a predetermined speed.  The drive block slides axi-ally away from the cartridge releasing the coupling pressure exert-ed thereon, upon the pivotally connected center point of the links moving radially outwardly past the imaginary line of the link pair to instantaneously disengage the coupled members.

The valve functions in perhaps its most important utilization to maintain a static pressure which may be varied in accord-ance with the strength of the current supplied to the solenoid of the valve.  The valve is constructed for operation by which an output pressure is modulated, according to the current strength of the solenoid, between two supply pressures admitted to separate portions of the valve.  One supply pressure is lesser and the other is greater than generally contemplated output pressure.

Abstract: ABSTRACT a lightweight transversely pivoting and longitudinally sliding skate carriage exhibiting exceptionally low friction, introduces a high degree of sensitivity into the process of skate sharpening, facilitating very light grinding cuts and low uniform traversing speeds, enabling a relatively unskilled operator to product superlative surface finishes and accurately maintain the blade "rocker" profile.  The carriage pivotal axis is so located and the skate blade so posi-tioned that the "hollow grind" is accurately centralized throughout the length of the blade.  The low friction, pivotal provision enables the blade to be held in sensitive contact with the cutting wheel controlling the depth of cut, whilst the longitudinal sliding provision permits sensitive control of rate of cutting lengthwise along the skate blade.  The skate carriage is readily removeable and being lightweight facilitates inspection of the blade surface during the course of sharpening, it may be fitted with rolling elements to accommodate both the pivotal and longitudinal motions.  The longitudinal profile or rocker of the blade may be controlled by mounting a template to the carriage parallel to the longitudinal axis, which engages a stationary roller throughout the course of longitudinal travel, thereby replicating the template profile onto the blade during the sharpening operation.
