Filed: 1970-07-03
Abstract: 1320780 Making pressure vessels KOBE STEEL Ltd 3 July 1970 [5 July 1969] 32425/70 Heading B3A A method of making multi-layer pressure vessels, comprises making multi-layer cylindrical units 7, from heat hardening metal or from thick metal plates which units are stress relieved by annealing, joining the units to each other and to end plates 6 by circumferential welding and annealing the circumferential welds 8 for stress relief. An inner cylinder is bent from a Cr-Mo steel and welded longitudin. ally, the cylinder being preferably coated with a corrosion-resistant layer on its inner surface. Further layers of the same steel are laid or wrapped around the inner cylinder and secured thereto by longitudinal welds. The inner cylinder may be annealed prior to the addition of the further layers, in which case the annealing conditions may be different for the complete unit 7 provided the stress relief of the inner cylinder is not affected. The ends of the units 7 are coated with weld material (5) before annealing, Fig. 4 (not shown). Individual units 7 are welded together and end plates 6 of the same Cr-Mo steel welded at each end. The welds 8 are heated on their inner and/or outer surfaces by electric or gas means, the annealing of the welds being facilitated by the presence of the previously applied weld material 5. The pressure vessels may alternatively be made from structural steel plates of at least 20 mm. thickness.

Title: Purification of polymers
Filed: 1963-08-20
Abstract: Solutions of polymers of one or more olefinically unsaturated monomers which have been obtained by polymerizing the monomers in the presence of a catalyst containing a metal at a temperature above the melting point of the polymer are purified by (1) removing at least 50% of the catalyst residues from the solution by mechanical means, (2) concentrating the solution, solidifying the polymer by extruding the concentrate, allowing the extruded concentrate to cool, and (3) contacting the solidified polymer in particulate form with a solution of a chelating agent for the metal and separating the solution of the metal chelate from the solid polymer.  In a preferred embodiment the solvent for the chelating agent is also a solvent for low molecular weight, amorphous or greasy polymers present in the polymerizate. The preferred polymers are polyethylene, polypropylene, and copolymers of ethylene and propylene. The catalyst is generally of the stereo-specific type, i.e. a mixture of a reducing and reducible compounds such as Li, Na, K, LiAl(C4H9)4 LiC4H9, NaAlH2, NaH, LiH, LiAl(C2H5)4 or LiAl(C6H13)4 with TiCl4, TiCl3, VCl4, or VCl3.  The preferred polymerization temperature range is from 150 DEG  to 250 DEG  C.  Separation (1) may be effected by filtration or centrifuging.  The chelating agents are 1,3-dicarbonyl compounds such as diketones, keto esters and/or keto acids.

Abstract: 536,903. Grinding cylindrical bores. STEVENS, A. H. (Ex-cell-O Corporation). Dec. 28, 1939, No. 32983. [Class 60] A device for lapping or abrading cylindrical bores comprises abrasive segments 63 of a cylinder each having a flat and preferably inclined face 65 with a longitudinal groove 66. This face may be engaged by a thin metal plate 68 having a rib 69 to fit the groove 66 and a groove 70 which is engaged by a rib 61 of a tapered mandrel 21. A wire 71 extending from the end of the plate 68 has an end 72 at right angles which can be passed through a groove 62, Fig. 10, of the mandrel into a groove 73 of a flanged collar 43 which is then rotated on the mandrel to lock the wire and hence the segment 63 to a hollow spindle 24 so that relative axial movement of mandrel and sleeve causes radial movement of the segments. The mandrel has a head 40 having bayonet-slot engagement with a pin 37 passing through slots 38 and secured to a bush 35 in threaded engagement with a sleeve 32 which can be rotated, to adjust the segments 63, but is normally held by a friction brake 50.

The core carries a metallic disc 16 provided with metallic rods 17 adapted to dip into mercury cups 19, the bottoms of which are connected by screws 21 to the leads from the writing-machine and the set of lighting switches. The coils 27 ...29, Fig. 8, for the lighting and extinguishing switches are wound round a body which houses two copper tubes 30, 31 separated by a gap 32 and closed at the ends bv soft iron 33, 34 connected to the lamp circuit. Two softiron members 37, 38 spaced apart by an insulating piece 39 are caused to slide with easy friction within the tubes 30, 31 in one direction or the other according to whether the coil 28 or the coil 29 is energized. When the winding 28 is energized by the current from the writing machine, the mass 37 .. 39 is moved against the fixed member 33, and the current flows through the member 34, the winding 27, and the thimble 40 to the lamp. The winding 29 serves to extinguish the lamp, the mass 37 .. 39 breaking the circuit at the copper tubes 30, 31. These switches may be replaced by a pair of coils which actuate a pivoted armature in opposite directions, the armature carrying a steel rod adapted to dip into a mercury cup . The soft iron pole ends of the coils are shaped as halfcrescents.

Abstract: 961,187. Travelling wave tubes. RADIO CORPORATION OF AMERICA. Sept. 26, 1960 [Oct. 29, 1959], No. 33045/60. Heading H1D. In a travelling wave tube provided with a delay line consisting of transverse loading elements in a hollow waveguide a set of electrodes is introduced interleaved between the loading elements to form with the loading elements a periodic electrostatic focusing system. The delay line bars 3, Fig. 3, may or may not have extensions forming drift tubes and the set of electrodes 7 are connected to a strip which may or may not be connected to the waveguide wall or may be so connected by coaxial chokes. In the embodiment of Fig. 9, consecutive delay line bars and electrodes are rotated by 90 degrees, the electrodes being at 45 degrees with respect to the bars so that the structure simulates a helix. The chokes 11 are #/4 open ended coaxial lines with metal rods 15, metal cups 17 and a ceramic sealing tube 19. The waveguide is a stack of metal blocks and plates. The chokes may be used in Fig. 3. In Fig. 12 the partitions 23 with drift tubes 25 have segmental coupling apertures alternately on opposite sides. The stack of square metal blocks and plates are brazed or soldered together. Rods 31 of lossy material extend through and are brazed to a ceramic support 33 brazed to the block. The output is taken from a rectangular waveguide having an oval window and a similar structure is used for the input. The lossy rods 31 are of carbonized ceramic and may taper. The gun comprises indirectly heated cathode 43, focusing electrode 47 and anode 49, the cathode and anode having disc seal leads through ceramic rings. Plate 59 is optional. The lossy rods 31 may be replaced by metal rods of random lengths, or of equal lengths with D.C. connections of unequal lengths or of equal lengths extending through a lossy bar or strip to prevent oscillations on the eletrode structure. The inner surfaces of the drift tubes can be double conical to improve the focusing field distribution. The tubes may be backward wave amplifiers or oscillators or forward wave amplifiers.
