Abstract: ABSTRACT OF THE DISCLOSURE    A train position control arm adapted for use in handling cars of a unit train in a movable train positioner and in a stationary train holder.  The arm is proportioned to engage a car coupler from a zone limited to the area immediately above the coupler so that a symmetrical pair of such arms may be simultaneously employed at the same location on a mating pair of couplers.  A coupler engaging head of the arm includes means for engaging and disengaging a coupler under full compression of buff loading.  In a train holder apparatus, the are is pivotally supported on a horizontal axis spaced from the tracks and at substantially the same height as a car coupler.  A stationary base supportingthe arm includes shock absorbing means adapted to resist impact forces on the arm along a line coincident with the pivot axis.

Abstract: ABSTRACT OF THE DISCLOSURE               A lever-operated latching device for securing in endwise coupled relation a socket portion and mating shank of axially aligned auger sections of an auger mining machine.  The latching device is designed to be of minimum radial dimension so as to fit in a hole of limited radial cross section bored by the auger machine, and includes a latch pin that reciprocates in a passage formed in the socket portion between an extended position in latching engagement with the shank and a retracted unlatching position.  The pin is biased by a spring toward its extended position and is retractable by a lever that engages a retractor element on the pin and that also acts as limit means that prevents the pin from extending beyond its extended latch-ing position against the force of the spring.  Openings are provided to permit removal by the latch pin of debris that could impair operative movement of the latch pin.

Abstract: ABSTRACT OF THE DISCLOSURE      A system is provided for pretesting electronic memory locations and automatically identifying faulty memory sections.  The system includes read/write memory means for storing a plurality of binary encoded words at a plurality of address locations, each word having at least two binary bits, the memory means initially being cleared to a condition in which all of the binary bits thereof should be of the same type; identifying means coupled with the memory means and responsive to a readout of the words stored therein for identifying a faulty bit of a word at any address location which is not cleared; addressing means for selecting different address locations in the memory means; and means coupled with the identifying means for causing the addressing means to select a new address location upon identification of a faulty bit by the identify-ing means.  The system pretests all data bit locations for each address prior to the entry of any data into that address, and automatically skips an address having a faulty data bit location in it.  In addition, the system functions, upon reading out of data information from the memory chips, uniquely to identify any faulty MOS RAM memory chip, so that such chip may be removed and replaced if desired.  This system effectively prevents the entry of data into a faulty memory address location.  It is capable of pinpointing the location of a faulty memory chip without requiring specific testing for faulty memory locations. The identification of the faulty memory chip is accomplished during normal operation of the system without disturbing the normal operation.

Abstract: PRODUCTION OF URANIUM DIOXIDE              ABSTRACT OF THE DISCLOSURE         A continuous, four stage fluidized bed process for converting uranium hexafluoride (UF6) to ceramic-grade uranium dioxide (UO2) powder suitable for use in the manu-facture of fuel pellets for nuclear reactors is disclosed.         The process comprises the steps of first reacting UF6 with steam in a first fluidized bed, preferably at about 550°C, to form solid intermediate reaction products UO2F2, U3O8 and an off-gas including hydrogen fluoride (HF). The solid intermediate reaction products are conveyed to a second fluidized bed reactor in which the mol fraction of HF is controlled at low levels in order to prevent the formation of uranium tetrafluoride (UF4).  The first intermediate reaction products are reacted in the second fluidized bed with steam and hydrogen at a temperature of about 630°C.          The second intermediate reaction product including uranium dioxide (UO2) is conveyed to a third fluidized bed reactor and reacted with additional steam and hydrogen at a tempera-ture of about 650°C producing a reaction product consisting essentially of uranium dioxide having an oxygen-uranium ratio of about 2 and a low residual fluoride content.  This product is then conveyed to a fourth fluidized bed wherein a mixture of air and preheated nitrogen is introduced in order to further reduce the fluoride content of the UO2 and inc-rease the oxygen-uranium ratio to about 2.25.

Abstract: Abstract The loading apparatus of this invention is capable of handling heavy loads such as large round bales of hay weighing fifteen hundred pounds or more without requiring the use of hydraulic, electrical or any other auxiliary power source.  The apparatus includes a ground wheel supported portable frame hav-ing a tongue structure connectible to a tractor and with the portable frame by a lost motion means.  A load carrying frame is movably supported on the portable frame for movement between a lowered bale loading position and an elevated bale transport position in response to the lost motion of the tongue structure relative to the portable frame.  With the load carrying frame in its loading position and the tractor advance, a pair of lift members on the load carrying frame are moved into engagement with the ground wheels for movement forwardly and upwardly there-on to lift the load carrying frame to its transport position. Means are provided for disengaging the lift members from the ground wheels as the load carrying frame approaches its trans-port position wherein it is automatically and releasably locked against movement to the loading position.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention consists of three process improvements in the so-called multi-step Piper-Montgomery process designed especially to produce the antifolate methotrexate which is closely related to both aminopterin and folic acid.  2,4,5,6-tetraaminopyrimidine sulfite is one starting material and is usually produced in the form of the bisulfite in an acetate buffer. The present modification positively produces the hydrochloride from the bisulfite and eliminates the acetate buffer utilized in prior art pro-cesses.  Subsequently, a pteridine ring is formed from the pyrimidine hydrochloride using dihydroxyacetone at pH 5.5?0.2 to form the second ring.  This strict pH control together with the use of hydrochloride salt minus the acetate buffer assists in preferentially favoring the formation of 2,4-diamino-6-hydroxymethylpteridine.  Subsequently the 6-hydroxy-methyl compound is converted to the hydrobromide acid salt and reacted with three moles of a triphenyl dibromophosphorane and phosphazine protecting groups are formed on the amine groups of the pteridine ring as the 6-hydroxymethyl group is transformed to 6-bromomethyl, a key intermediate.  The present process leaves the protecting phosphazine groups on the primary amino groups to discourage side reactions during sub-sequent alkylation of the other major reactant, ethyl N-(p-methylaminobenzoyl)-L-glutamate.  Furthermore, ethyl N-(p-methyl-aminobenzoyl)-L-glutamate, the other reactant, is uniquely produced for the present multi-step reaction by a process pro-ceeding from ethyl N-(p-trifluoromethylaminobenzoyl)-L-glutamate by utilizing an alkali metal hydroxide in a lower (C1-C6) alkanol wherein the protective trifluoroacetyl groups are removed.  This step uses a special mixture preferably of an alkali metal hydroxide in ethanol and optimally 1 equivalent of KOH in 20% ethanol at or below ambient temperature where the mixture is added slowly to keep the reaction pH below 9.          The combination of these improvements results in the increase of an overall yield of methotrexate from the named starting reactants from about 25% to approximately 40-50%.
