Abstract: Une machine à couper la paille et qui est particulièrement conçus pour empêcher la blocage des pouteaux rotatifs et pour permettre le déplacement de la machine pour son utilisation en tout endroit désiré et pour éjection de la paille coupés dans toute direction désirée.  Cette machine à couper la paille comprend un plateau muni d'une série de fentes et des couteaux montés sur un axe disposé sous et parallèle ou plateau de manière que, lors de leur rotation, les coutenux fassent saillie du plateau à travers  les fentes.  La balle de paille à couper est insérée dans un tube ouvert aux deux boute et qui tourne selon son axe vertical.  La face inférieur de la belle de paille repose sur le plateau et est engagée par les couteaux qui heshant la paille et soulèvent la base contre son poids.  Les couteaux balaient toute lu base de la balle de paille perce que celle-ci est tournée par le tube.  Le blocage des couteaux est évité car il n'y a pas cissiliement de la paille étant donné que les faces des couteaux sont separées des bords des fentes.  Cette machine à couper la paille inclut une base montée sur rouee pour le déplacement de la machine et pourvue d'une sortie pour permettre l'injection directionnelle sélective de la paille coupés.

Abstract: ENGINE DRIVEN HEATING SYSTEM COMPONENTS FOR              STIRLING ENGINES                ABSTRACT OF THE DISCLOSURE         A mechanical drive system permits a single electric motor to drive at least three rotary components necessary to the cold starting of a Stirling engine.  These components comprise a rotary preheater, an air atomizing pump for facilitating proper injection of fuel particle size, and a combustion air blower, all necessary to heat the working gas of a Stirling engine prior to engine cranking.  The drive system employs a shaft, offset from the engine driven element but drivingly connected thereto.  A clutch is interposed between the offset shaft and the rotary starting components, as well as between the electric motor drive and said components.  Thus, drive is alternatively transmitted, first from said motor to the component to permit engine temperature increase, crank-ing is then established, and then drive is transmitted from the engine driven element to said components.

Abstract: VERTICAL AXIS HERMETIC ROTARY HELICAL SCREW COMPRESSOR WITH IMPROVED ROTARY BEARINGS AND OIL MANAGEMENT            ABSTRACT OF THE DISCLOSURE    In  a  vertical  hermetic  compressor,  an  inner cylindrical housing coaxially mounted within a sealed outer enclosure,  sealably carries at its lower end, paired helical screw rotors defining with the inner housing a screw compressor compression chamber and supports coaxially with one of the screw rotors and constituting   an   axial   extension   thereof   the compressor   electrical   drive  motor   rotor   by longitudinally spaced tapered roller bearings.  Oil is bled from the sump and fed to the suction inlet tube to the compressor upstream of the working gas filter.   Compressed  working  fluid  is  discharged axially  downwardly  with  the  lower  tapered  roller bearing assembly providing a minimal high pressure gap between the screw rotor ends and the stationary end plates.  Entrained oil from the discharge passage which extends through the electric motor rotor seeks the suction side of the compressor through the upper of the two tapered roller bearing pack assemblies for controlled  continuous  lubrication  of the  upper bearing  assembly.   The  compressed  working  fluid discharges axially through the center of the sealed outer enclosure at its upper end free of oil which is separated by  impact with a curved plate deflector overlying the upper end of the electric motor and by centrifugal  force  provided by  the  electric  motor rotor rotation.  The upper bearing pack assembly for the screw rotors may employ needle bearings instead of tapered roller bearings,  and the lower bearing pack assemblies may  incorporate radially extending needle bearings for thrust take-up in lieu of one set of tapered roller bearings, with the needle bearings carried  by  a  spherical,   self-aligning  mounting assembly.   A  capillary  line  passing  through  the compressor inlet passage carries oil from the sump to an injection port opening to a closed thread just after suction cutoff for lubricating and sealing of the screw rotors.

Abstract: ABSTRACT-"Apparatus for reading an optical record carrier having a radiation reflecting information structure".           An apparatus is described for reading a record carrier with an optical radiation reflecting information structure. The path of the read beam includes a plane-parallel plate, whose surface area is substantially smaller than the cross-sectional area of the read beam, which plate ensures that the beam portion which passes through the plate cannot interfere with the rest of the read beam. After reflection by the record carrier the said beam portion passes through the radiation-deflecting element which de-flects the beam portion to two radiation-sensitive detectors. The position of the radiatin spot formed by the said beam portion is proportional to the degree of focussing of the read beam on the information structure.

Abstract: PROCESS FOR PURIFYING RARE-EARTH COMPOSITIONS    USING FRACTIONAL SULFATE PRECIPITATION       Abstract Of the Disclosure A process is disclosed for purifying a compo-sition comprising at least one rare-earth element.  The process is useful for removing radioactive impurities from these elements.  The process comprises the steps of: (1)  forming an aqueous solution of the composition to be purified having a pH between 4.0 and 6.5; (2)  precipitating a portion of the rare earth and the radioactive impurities by adding to the solution, while maintaining the pH between 4.0 and 6.5 (i)  a soluble barium or strontium salt; (ii)  a soluble aluminum, magnesium or zirconium salt; (iii)  a selective precipitating agent, and (iv)  a sulfate ion-providing salt. The preferred selective precipitating agent is 8-hydroxy-quinoline.  After precipitation, the process is completed by the steps of: (3)  separating the solution from the precipitate and (4)  recovering purified rare earth from the solution. The process produces highly purified rare earth which can be used to form phosphors for X-ray screens.
