In the first stage the higher nitrogen oxides contained in the gas mixtures formed in the dissolution of the nuclear fuel with nitric acid and in the denitration of the uranium and pluto-nium nitrates are reduced to nitric oxide (NO) and iodine is ab-sorbed.  In the second stage, the gas mixture of the first stage is separated into a fraction containing the volatile, radioactive substances and nitric oxide and a fraction mainly consisting of nitrogen and xenon.  Oxygen is added to the liquid, radioactive substances and enriched with volatile, radioactive substances.          The enriched oxygen and the fraction of the second stage con-sisting of volatile, radioactive substances and nitric oxide are jointly subjected to a chemical treatment and the oxygen is reacted with the nitric oxide.

The crown surrounds a central opening which is closed by hinged hexagonally-shaped flaps locked in position when the loaded containers are stored or transported.          The flaps are unlocked to swing down to the sides of the opening so that they do not interfere with unloading of the container thereby insuring complete emptying.  The use of an impervious foldable sleeve extending from the opening in the container and which unfolds to serve as a funnel through which the material is unloaded into a hopper beneath the pallet is also disclosed.  Also disclosed are vertical support struts for  interconnected pallets  so  that  the containers may be stacked vertically.

Abstract: ABSTRACT OF THE DISCLOSURE           Polyolefins having a wide distribution of molecular weights are prepared in a plural stave  process, by initially poly-merizing the olefins in the presence of a solvent, hydrogen and a highly active Ziegler type catalyst under pressure, and beneath a gas phase containing an inert gas, to form in the first stage a polymer having a relatively high molecular weight.  The polymeri-zation reaction mixture from the first stage is continuously flowed to a second stager reactor.  The second stage reactor is maintained at a relatively lower pressure, such that the flow is driven by the higher pressure in the first stage.  The  second stage is agitated and the polymerization reaction mixture is maintained beneath an atmosphere containing olefins and hydrogen gas.  Polymers of rela-tively lower molecular weight are formed in the second stage.  The product continuously removed from the second stage contains a poly-mer having a wide distribution of molecular weight.

Abstract: ABSTRACT OF THE DISCLOSURE    A phonograph cartridge replaceable stylus assembly is pro-vided.  The assembly comprises a housing having a nonmagnetic tube affixed thereto.  The tube has a forward end and a rear end extending outwardly away from the housing.  A nonmagnetic stylus arm extends through the tube forward end.  A jeweled stylus is mounted to the front of the arm.  The rear end of the arm passes through an elastomeric damper positioned within the tube.  The damper serves as a universal pivot joint for the arm.  The damper comprises a cylindrical member having a forward edge and a rear edge.  The tube is crimped along a circular crimp line engaging the damper intermediate the forward and rear edges with the por-tions of the damper that do not engage the crimp also being free of the tube.  A magnetic member is positioned within the tube secured to the arm and adapted to move therewith in response to motion of the jeweled stylus and following the grooves of a record.  The arm passes through and extends beyond the magnetic member terminating within the elastomeric damper in front of the crimp.  A tension-free tie wire extends rearwardly from the rear of the arm and is secured to the tube.  The tie wire serves to restore the arm and hence the magnetic member to its zero position.

Abstract: ABSTRACT OF THE DISCLOSURE      An electric typewriter of the type having individual type elements for each character has attached thereto a system for controlling the actuation of the type elements and the control functions of the typewriter by digital signals.          The digital signals may emanate from a remote central pro-cessing unit or other device.  The control system is an attachment to the typewriter which does not interfere with the normal manual operation of the typewriter.  The control system is mounted in a housing which is placed under the typewriter in predetermined alignment with the key lever actuation means and employs an electromagnetic actuator to set a condition for a mechanical actuator for each key lever.          A mechanical actuator initiates a key stroke if the electro-magnetic actuator is positioned in an ON position and does not initiate a key stroke if the electromagnetic actuator is in the OFF condition.  The electromagnetic actuator does not supply power for the key stroke operation but merely sets a condition for the mechanical actuator which initiates a key stroke through the typewriter key power drive to operate and print a character.
