Abstract: ABSTRACT     Cesium is recovered from a cesium-bearing mineral such as pollucite by extraction with hydrochloric acid to obtain an extract of cesium chloride and other alkali metal and polyvalent metal chlorides.  The iron and aluminum chlorides can be precipitated as the hydroxides and separat-ed from the solution of the alkali metal chlorides to which is added potassium permanganate or other water-soluble permanganate to selectively precipitate cesium permanganate.          The cesium precipitate is then separated from the residual solution containing the metal chlorides.  The cesium permanganate, which is in a very pure form, can be converted to other cesium compounds by reaction with a reducing agent to obtain cesium carbonate and cesium delta manganese dioxide.

Abstract: CYLINDRICAL BALER HYDRAULIC CIRCUIT FOR CONTROLLING BALE     CHAMBER TENSION AND OPERATING BALE DISCHARGE GATE            Abstract of the Disclosure A cylindrical baler is comprised of an adjustable bale-forming chamber for forming spirally wound, cylindrical bales A completed bale is discharged on the ground through a rear gate.  The chamber is comprised of a plurality of longitudinally extending, side-by-side belts supported on a plurality of transverse rollers.  The chamber is adjusted by a pair of belt tension rollers engaged with the bale chamber belts and supported between a pair of pivotal mounted belt tension arms which are displaceable as the diameter of a bale in the chamber increases during formation.  A hydraulic circuit controls the tension applied to the chamber by the belt tension arms and rollers and also operates the bale discharge gate. A pair of hydraulic jacks are, respectively, mounted on each side of the baler and connected between the bale discharge gate and the belt tension arms.  To properly tension the belts, a non return valve isolates the hydraulic jacks from the tractor's hydraulic supply and the jack chambers are connected in closed circuit through an adjustable pressure valve to apply a resistance to fluid flow from one chamber of each jack to the other.  The non return valve is pilot controlled and is opened to permit return fluid flow to the tractor supply when the jacks are actuated to open the rear gate.  Thus, each jack performs a double function of braking the movement of belt tension arms and rollers and operating the bale discharge gate, thereby, providing a simple, low cost, hydraulic circuit for belt tensioning and gate operation.

Abstract: HIGH SPEED DATA BUS STRUCTURE       AND SYSTEM        ABSTRACT OF THE INVENTION       A very high speed data bus system for communication among the various functional units that may constitute a large computer system.  The functional units are mounted in immediately adjacent connectors on the backplane to define a populated section of effective characteristic impedance Z0' and one or two unpopulated sections of impedance Z0.  A popu-lated end of the transmission line is resistively terminated with a resistance corresponding to Z0' while the unpopulated end is terminated with a resitance corresponding to Z0.  The border between the populated and unpopulated sections is terminated with a resistance corresponding to 1/(1/Z0'-1/Z0), thus eliminating signal reflections.  Driver gating circuitry responsive to first and second data input signals, an enable signal, and a conditional inversion input signals performs multiple levels of gating with a minimum of propagation delay.  The preferred differential receiver amplifies a rela-tively low level differential input signal and performs an exclusive OR function with a conditional inversion signal with a minimum propagation delay between the signal input and an output line pair.  Each functional unit has an associated port which operates to accept all related information that makes up a communication, or if this cannot be done, to accept none of the information.  To implement the indivisi-bility of transfers, the control logic for each port includes screening circuitry responsive to the state of the ports's functional unit for selectively accepting or rejecting bus information, and further includes screening constraint cir-cuitry to ensure that the port accepts all or none of the information that makes up the transfer.  Depending on the flag, the rejection may be total, or may apply only to a designated class of transfers.

Abstract: A PRIORITY VALVE                   Abstract of the Disclosure A priority valve is disclosed for controlling fluid flow between a power source and a secondary hydraulic function operated by the power source. The priority valve includes a housing having first and second bores formed therein.  An inlet passage connects the power source to the first bore while an outlet passage connects the first bore to the hydraulic function.  A priority function is also fluidly connected to the power source upstream of the priority valve.  A valve spool is positioned in the first bore and is movable between the first and second ends of the first bore.  The valve spool has an annular groove which is in constant communication with both the inlet passage and with the first end of the first bore.  The valve spool is movable between a first position blocking fluid flow from the first passage to the outlet passage and a second position permitting fluid flow therebetween.  A pin is movably positioned in the second bore and has an enlarged end which extends into the first bore.  Springs are present for urging the valve spool toward the first position and the pin toward the spool valve.  The priority valve further includes a load signal passage connecting the priority function to the second end of the first bore.  When full fluid flow is demanded by the priority function, the pressure difference between the load signal passage and the inlet passage decreases causing the valve spool 38 to move toward its first position.  When the priority valve demands less than full flow, the pressure difference between the load signal passage and the inlet passage increases and the spool valve is allowed to move toward its second position.  Should a situation occur wherein the priority function demands pressure approaching a maximum pressure which can be delivered by the power source, the pressure within the load signal passage increases and this pressure causes the enlarged end of the pin to contact the valve spool and force it toward its second position thereby assuring fluid flow between the power source and the secondary functions.

Abstract: ABSTRACT   Weighing a number of objects in succession To weigh objects in quick succession, the objects are projected with a known horizontal velocity onto a ramp which has a surface which curves down through 90°.  The ramp can move horizontally in response to the impul6e corresponding to the change in horizontal momentum of the object.  A transducer senses the movement of the ramp and the output horizontal velocity of the object is sensed, enabling the change in horizontal velocity to be calculated.  The mass of the object is calculated from the horizontal movement of the ramp and the change in horizontal velocity of the object.  In order to obtain accurate sensing of the movement of the ramp, the transducer is a linear variable differential transformer having a primary winding energised by a cyclical carrier signal and two matched secondary windings in series; the secondary winding output signal is rectified to a corresponding DC voltage having ripple components, and a sample is taken of the signal at the zero voltage of the principal ripple component.

Abstract: ABSTRACT:      A fiberizer for disintegrating fibrous sheets and a method of fiberizing using a rotor having peripheral teeth arranged within bands which extend transversely around  the rotor axis is disclosed.  The tooth pattern in each band is circumferentially extending and shaped approximately in a sinusoidal wave on the rotor periphery extending in the direction of rotation, and providing a substantially sinusoidal distribution of impacts against a sheet fed to an anvil in the form of simple harmonic motion along a cross direction impact line adjacent the anvil and thus transversing impacts within adjacent strips of the sheet corresponding to the bands.  Individual points along the width of the fibrous sheet are periodically impulsively loaded by the impacts when they are at a period of highest response, i.e., when the initial stress level has been increased to the highest optimal stress without causing fiber damage, and producing mechanical disturbances within the sheets which cause vibrations and break interfiber bonds so as to precondition the sheet as it is fed to the anvil.
