Abstract: PROCESS FOR MANUFACTURING CYLINDER-SHAPED HOLLOW      PARTS                 Abstract of the Disclosure The herein disclosed process relates to mechanical en-gineering techniques and, more particularly, it relates to the manufacture of cylinder-shaped hollow parts.     This process enables one to manufacture parts having low surface roughness in a high yield.     The process resides essentially in that a hollow blank is produced by electroslag melting at a rate of casting the blank of 0.3 to 0.6 mm/s, after that, the hollow blank is surface hardened by a plasma jet shaped in a plasma generator with a current strength of 220-320 A, at a linear revolution rate of the blank relative to the plasma generator of 3 to 10 mm/s and a gap between the plasma generator and the blank of 2 to 10 mm; thereupon, the finishing step is per-formed by way of magnetoabrasive treatment wherein pole pieces are imparted vibrations the product of whose frequency by the length of the blank surface being treated covered by the pole pieces is selected to be divisible by an integer within the tenfold linear rate of the blank revolution.

Abstract: ABSTRACT          Improvements in or Relating to Travelling Wave Tubes The invention provides a travelling wave tube having a directly heated cathode.  Cathode material is applied in a depression in one U-shaped member of a high resistance alloy material whilst the return path for heater current is provided by another U-shaped strip member beneath the first.  The configurations of the two strip members are similar so that stray magnetic fields generated by the equal but opposite currents flowing therein, tend to neutralise one another.  In another embodiment the two strip members are replaced by generally cylindrical members, one member being within the other.  The surface of the member providing the return path for heater current is polished where it faces the member carrying the cathode material so as to reflect back heat radiated by the lastmentioned.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a reaction vessel which is used to carry out an exothermic reaction of a mixed gas consisting of a plurality of elements in the presence of a solid catalyst.    In a conventional reaction vessel of this type, it is difficult to maintain an optimum temperature of the exothermic reaction, and its economy is poor. The present invention is directed to the reaction vessel in which central pipes are disposed in a plurality of reaction pipes and circular spaces between these pipes are packed with a catalyst, whereby an unreacted feed gas can be caused to flow upward from lower positions of the central pipes and can be then mixed with another unreacted feed gas having a lower temperature, and the resultant mixed gas can be caused to flow through the catalyst layers downward from above.    The present invention permits accomplishing the exothermic reaction while maintaining the optimum temperature by virtue of the above-mentioned constitution, and is ecomonical.    The present invention can be applied to reaction vessels by which the exothermic reaction is carried out for the mixed gas consisting of a plurality of elements, as in the synthesis of methanol.

Abstract: SHORT FUEL ELEMENT ABSTRACT OF THE DISCLOSURE   Fuel bundles for use in a pressure tube reactor each comprise a cylindrical assembly of fuel rods extending between a pair of end plates to which the rods are attached.  The individual rods have a sheath construction of predetermined length to permit the insertion of a plurality of bundles within existing pressure tube fuel channels, previously containing a lesser number of longer bundles.  The adoption of shorter rods militates against rod distortion under thermal and coolant flow forces, to obviate the former necessity of providing spacing appendage means attached to the fuel rod sheaths intermediate the bundle and plates, thereby simplifying manufacture and enhancing the metallurgical dependability of the rod sheath.  There is further provided a bundle assembly comprising two or more of the improved fuel bundles secured in end-to-end relation, in predetermined angular relation about the polar axis of the bundle assembly.
