Abstract: GAME HAVING GAMEBOARD    AND WHEELED TOY            Abstract of the Disclosure A child's game which comprises a toy capable of spinning in a circular motion or path and then travelling in a straight or substantially straight line at the end of its travel path and an arena which is provided with a wall surrounding the arena perimeter, the wall having a single opening therein through which a toy can travel, the arena also having a central start area and other designated areas therewithin for use in playing the game.  The designated areas can be sectors, one side of which is an arc formed by the wall and the perimeter of the arena.  Each of the sectors has a predetermined designation in accordance with the rules of the game.  The toy has a set of wheels which, upon being caused to rotate at high speed, causes a fly-wheel within the toy  to rotate, raise one wheel from the arena surface, and permit the toy to travel in a circular path when placed in the center of the arena until the fly-wheel has reduced its speed to some predetermined point whereupon both of the wheels are on the ground and the toy will then travel in a straight path.  The toy will either travel out of the arena through the opening in the perimeter wall or it will move forward and bump into the wall and land in one of the sectors.   Assuming that the toy is in the form of a mouse, several sectors can be designated to provide wedges of cheese in varying numbers with other sectors providing penalties.          The game can be won by landing the mouse on sectors having predetermined numbers of cheese wedge designations whereby a wheel of cheese can be completed by the winning player before landing on a penalty sector, or a player may win at once if the mouse travels through the single wall opening.  All players are, at all times, attempting to collect cheese wedges.

Abstract: Procédé et dispositif de séparation d'émulsions par coalescence.  Le procédé est du type des procédés dans lesquels l'émulsion est amenée à traverser un lit fixe coalesceur comprenant un matériau à l'état divisé ou poreux, mouillé préférentiellement par la phase dispersée.  Le procédé consiste à guider à la sortie du lit coalesceur la phase dispersée  vers une couche extrême constituée par cette phase déjà séparée; ce guidage est réalisé au moyen d'un garnissage d'un matériau à l'état divisé ou poreux, mouillé préférentiellement par la phase dispersée, ce garnissage plongeant par sa portion extrême dans la couche de phase dispersée déjà séparée.  Le procédé peut être appliqué pour séparer des émulsions directes ou inverses, constituées par une phase organique et une phase aqueuse, il permet d'accroître de façon considérable les performances des phénomènes de coalescence et de réduire les limites opératoires au delà desquelles ces phénomènes ne sont plus opérants dans les procédés classiques.

Abstract: ABSTRACT OF THE DISCLOSURE      Loss of thiocyanate ions used in solvent extraction processes is minimized by adjusting the acid concentrations of aqueous process solutions to repress substantially completely ionization of the thiocyanate and contacting the aqueous process solutions with a liquid organic solvent to incorporate the thiocyanate therein as hydrogen thio-cyanate.      In a specific example, cobalt is separated from a nickel process solution by contacting the process solution with an organic extractant of methyl isobutyl ketone having hydrogen thiocyanate dissolved therein.  The cobalt-loaded organic extractant is stripped of its cobalt values by contact with a concentrated sulfuric acid solution, which minimizes losses of thiocyanate to the stripping solution, and produces a sulfuric acid solution containing cobalt, which can be treated to crystallize cobalt sulfate and to regenerate a concentrated sulfuric acid solution that can be recycled to the stripping operation.  Concentrated sul-furic acid is added to the nickel-containing raffinate which is then contacted with the stripped organic extractant to scavenge hydrogen thiocyanate from the raffinate.  The thiocyanate-free raffinate is treated for nickel and sul-furic acid recovery.     (1)

Abstract: ABSTRACT OF THE DISCLOSURE A current drive circuit for deriving a triangular current waveform for driving an inductive load, such as the field coils of a bubble memory, comprises a series of at least four diodes connected between the positive and negative input voltage lines.  A pair of switching devices, such as switching transistors, are connected in series such that each switching device is in parallel with two of the diodes.  The junction between the switching devices is also connected to one output for the inductive load. The intermediate diodes are connected together and to one side of a time delay circuit, the opposite side of which is connected to the second output for the opposite side of the inductive load.  A modification of the invention comprises a second diode and switching circuit connected between the time delay circuit and the second output.  The circuit operates on the fall time of the transistor only, not the rise time, thereby marking the circuit more efficient than prior art circuits and reducing power losses.

Abstract: DIGITAL SPEEDOMETER WITH INDEX COUNTER         CONTROL OF DISPLAY            ABSTRACT OF THE DISCLOSURE      A digital speedometer for indicating angular or linear velocity has an index counter to control update of the displayed velocity.  The purpose of the index counter is to prevent undesirable fluctuation of the displayed velocity where minor variations in velocity being measured have occurred.  The digital speedometer uses a pulsating input signal having a frequency proportional to the velocity to be indicated.  An oscillator circuit provides a clock frequency that is utilized in generating a counting period electrical signal.  During the counting period, the input pulses proportional to velocity are gated into a counter.          After each counting period, a comparison is made between the count currently being displayed and the count stored in the counter.  If a difference occurs, the index counter is incremented.  Only after the index counter has been incremented a plurality of consecutive times is the display permitted to be updated.

Abstract: 47,443 A SOLUTION MINING METHOD UTILIZING DISSOLVED OXYGEN     ABSTRACT OF THE DISCLOSURE          A method for leaching mineral values from an underground ore body in situ comprises introducing an oxygen-bearing gas into a pressurized saturation-disengagement chamber located above ground of the ore body where the oxygen-bearing gas becomes dissolved in a leach solution.          The leach solution with dissolved oxygen therein is then pumped into the well and through the ore body where the leach solution oxidizes the mineral values in the ore body permitting their solubilization and transport by the leach solution to a recovery well where the pregnant leach solu-tion is pumped above ground.  The pregnant leach solution is then treated to remove the mineral values therefrom.  Insur-ing that the oxygen-bearing gas is completely dissolved in the leach solution above ground in the saturation-disengage-ment chamber prevents gas bubbles from being pumped into the ore formation, thereby preventing loss of inffectivity.
