Abstract: Uranium trioxide is reduced to uranium dioxide using microwave radiation or radiofrequency radiation directed in such a way that the radiation encounters an interface between uranium trioxide and the uranium-containing reduction product without first having passed through that product. By this method, and also using a reducing gas, it is possible to obtain UO2 with an O:U ratio less than 2.04:1.

Abstract: A heavy equipment apparatus such as a feller buncher includes a mobile tilting undercarriage and a working upper that supports a boom and its working end portion. The undercarriage includes a frame and a deck with a spaced apart, generally parallel powered endless tracks for moving the undercarriage from one location to the other. A tower assembly is mounted on the deck of the frame and has a ball support rigidly attached thereto to define a rigid support with the frame. An upper is movably mounted to the undercarriage at the ball support with a tilting connection that enables the upper to tilt with respect to the undercarriage. A rotary bearing attached to the bottom of the upper enables the upper to rotate with respect to the undercarriage. A flange assembly forms the interface between the rotary bearing and the ball support. Extensible cylinders extend between the undercarriage and the flange assembly for articulating the upper relative to the undercarriage during use.

Abstract: Uranium fluoride compounds, in which the uranium is preferably present in the tetravalent or higher valency state, are reacted with a strong mineral acid, to yield a gaseous phase of hydrogen fluoride and a precipitate that is a uranium salt of the mineral acid. The precipitate can be subjected to thermal decomposition to recover the mineral acid and to obtain an oxide of uranium. The process provides an economical way of obtaining hydrogen fluoride from byproduct depleted UF.sub.6.

Abstract: A slip clutch and cutter blade apparatus for cane stalk harvesters provides a machine frame with a cutting mechanism in the form of cutter shafts powered by hydraulic motors. The cutter shafts have a plurality of knives thereon that pinch the cane therebetween as the shafts rotate to chop the cane wholestalks into billets. A flywheel is mounted on a flywheel shaft. A gearbox interfaces the flywheel and cutter blades. A flywheel clutch is used as a overload protection device for the chopper system. If overloading occurs, the flywheel slips and therefore limits the torque. The flywheel is placed on the bushing and clamped between the friction linings with the aid of the thrust plate, the cup springs, brake plate, brake plate cover, and bolts. The more the cup springs are compressed by the bolts; the higher the torque at which the flywheel slips.

Abstract: A process for removing molybdenum from uranium bearing solutions reduces molybdenum contamination of uranium product. The process employs solvent extraction techniques to remove molybdenum by using a molybdenum-selective extraction reagent of the chelating hydroxy-oxime type. The molybdenum-loaded extractant is stripped with dilute alkali for reuse. Where the uranium bearing solution originates from a solvent extraction process, a pretreatment stage is applied using an agent to remove entrained uranium extractant.

Abstract: Selection criteria are disclosed for choosing a coreactant RX that will improve the isotope separation in laser-activated chemical reactions which may proceed by the steps: ##STR1## The step of coreactant activation can be important in some exchange reactions but unnecessary in others. That is for some laser-activated chemical reactions, the second step may be absent.The selection criteria are based on the relative magnitudes of the bond-energies and therefore vibrational frequencies in the molecules .sup.i MY and RX, and the requirements for forming a Vanderwaals-like attachment complex. Also, the upper and lower limit of tolerable thermal (non-laser) reaction speeds are defined. It is shown further that it is necessary to restrict suitable RX candidates to those species which yield .sup.i MX product that does not participate in subsequent chemical reactions which cause isotope scrambling. The employment of a second auxiliary coreactant is recommended in certain cases if its interaction with the complex (.

Abstract: A compound MF.sub.n, where M is a metal and n is the valency of the metal and has a value between 1 and 6, is subjected to a thermal plasma at a temperature in excess of 3000 K to dissociate it into the metal and fluorine. Also present in the reactor is an added reactant that will react with the metal or the fluorine to prevent their recombination so that there is formed fluorine gas or a fluoride other than the fluoride of the metal M.

Abstract: A sugar cane harvester has a base cutter elevation control system that compensates for changes in terrain such as ruts, small hills, etc. by raising or lowering the base cutter. A forwardly positioned slipper assembly gives feedback as to upcoming changes in terrain. A sensor also monitors tire position as when the harvester sinks into soft spots, muddy spots and the like wherein base cutter position is adjusted to compensate for sinkage of the tires.

Abstract: An isotope separation arrangement for separating a preselected isotope from a mixture of chemically identical but isotopically different molecules by either photon-induced pure rovibrational or vibronic selective excitation of the molecules containing the atoms of the isotope to be separated from a lower to a higher energy level, and a chemical reaction of the higher energy level molecules with a chemically reactive agent to form a chemical compound containing primarily the atoms of isotope to be separated in a physicochemical state different from the physicochemical state of the mixture of chemically identical but isotopically different molecules. The chemical compound containing the atoms of the isotope to be separated may be subsequently processed to obtain the isotope.

Abstract: A wholestalk sugar cane loader apparatus is provided for the picking up and accumulating of windrowed wholestalk sugar cane from a cane field ground surface using a boom and grapple configuration that skews the grapple jaw travel path with respect to the longitudinal axis of the boom. This configuration allows use of a shorter boom and a shorter travel path. This configuration also allows greater spacing between the loader and the cane cart to improve cane quality by eliminating both cane rollover and the muddying of the cane which typically occurs by splashing of tires because of the close proximity of the cane loader and the cane cart.

The rotary piler assists in rolling the cane in front of the push piler and dislodges dirt, mud, and other foreign matter from the cane in the heap row being push-piled for loading. Also, by increasing the rolling action of the pushed pile, a large pile of cane can be pushed for a fuller grab in the loading operation.

Abstract: A sugar cane harvester having at its front end a topper section for cutting off the tops of the cane stalks and upper and lower sets of cane gathering arms which gather up the cane and bring it into the harvester for harvesting at its base and topping at its top. The topper section is carried on a vertically moveable base riding on vertical tracks for varying the height of the topping cuts, to which base is also pivotally connected the harvester ends of the upper set of cane gathering arms, thus interconnecting the topper cutter entry or harvester ends of the upper arms and the topper section for combined movement together. Variable length, telescoping bracing arms are pivotally connected between the left, upper and lower arms and the right, upper and lower arms, respectively, to provide stabilizing bracing to the upper sets of arms when they are vertically varied with the topper section.

Abstract: A compact respirator system for use either connected to stationary outlets for breathing gas or connected as a portable unit to a tube of breathing gas. A breathing bladder and a valve block form a unit that may be disposed either with the breathing bladder in a pressure chamber for conventional respiratory operation or with the breathing bladder removed from the pressure chamber for manual actuation. A pulse transmitter actuates a pressure pulse generator for providing the pressure chamber with intermittent pulses for compressing and expanding, respectively, the breathing bladder for said conventional respiratory operation. An automatic valve keeps open a pilot pressure channel to an expiratory valve forming a portion of a pilot valve, which latter also includes a patient-triggered valve for initiating rapid breathing assistance if the patient shows signs of beginning to breathe spontaneously.
