Title: Improvements in and relating to methods of introducing electric conductors into vacuum vessels
IPC: H01J5/42
Filed: 1937-10-11
Abstract: 484,875. Uniting metal to ceramic material by heat. BRITISH THOMSONHOUSTON CO., Ltd. Oct. 11, 1937, No. 27586. Convention date, Oct. 15, 1936. [Class 36] In a process for the manufacture of current leading - in conductors for vacuum vessels, of the type in which a metal ring is sealed to the circumference of a ceramic insulator by a glass flux, the glass 7 is first melted into an annular bulge in the metal ring 6 by means, such as a blow-pipe, forming an oxide coating on the ring, after which the ring is seated on the insulator 2 and together heated in a furnace having a neutral atmosphere until the glass runs, as shown at 8, into the crevice between ring and insulator. In the example, two metal tubes or rings 6 pushed upon the opposite ends of an insulator 2 are welded respectively to a flange 9 on a leading-in conductor 1 and a flange 11 on the wall 12 of a discharge vessel, this welding being effected either before or after the fusion of the glass 7. The ends of the insulator are reduced to form stops 10 against which the tubes 6 abut. In a modification, an additional conductor in the form of a Ranged metal tube is placed coaxially with the central conductor, with the flange located between the ends of two abutting tubular insulators which are coupled together by a metal ring bulged adjacent to its two ends to receive glass seals which are fused to the insulators ; the metal ring forms a terminal for the tubular conductor, which may be connected to a control grid of a vacuum discharge device.
Patent GB-275993-A (GB)
Abstract: 275.993. National Cash Register Co. Aug. 11, 1926, [Convention date]. Printing on inserted material.-The insertion of a slip to a position beneath the printing hammer 8 is normally prevented by a plate having prongs 14, but depression of a control key operates a detent 2 to remove the prongs from the receptacle opening. The detent actuates a bell-crank 22 fast on a shaft 21, and connected by a lever 20, links 17, 19 and a bell-crank 18 to the pivoted plate. Movement of the total-taking lever to total-taking position turns a cam 31 to rock a lever 28 connected by a link 27 to the bell-crank 18 to remove the obstruction and allow insertion of a strip during this operation also.

Title: Production of unsaturated aliphatic acids and catalysts therefor
Inventor: HADLEY DAVID JAMES
IPC: C07C51/25
Filed: 1960-09-08
Abstract: An aqueous solution of a cobalt salt of a volatile, or decomposable acid and a molybdate of ammonia or other nitrogenous base is heated to produce a precipitate, and the latter is heated at about 350 DEG -650 DEG C., ground and formed into pellets which are heated at about 500 DEG -650 DEG C.  Specified nitrogenous bases are ethanolamine, ethylamine, triethylamine, ethylene diamine, aniline piperidine, pyridine and hydrazine.  Specified cobalt salts are the nitrate, chloride, acetate, formate and oxalate of cobalt. The pellets may be used as catalysts in fixed or fluidized beds. In an example solutions of ammonium molybdate and cobalt nitrate are mixed at room temperature, the mixture is heated to boiling causing precipitation of cobalt molybdate which is filtered, washed, dried at 110 DEG C., heated at 400 DEG C. and pelleted.  The pellets are thereafter heated at 540 DEG C.  Specification 878,802 also is referred to.ALSO:A process for the production of acrylic acid or methacrylic acid comprises reacting at an elevated temperature in the vapour phase acrolein or methacrolein with a molecular oxygen-containing gas over a catalyst prepared by heating an aqueous solution of a cobalt salt of a volatile or decomposable acid and a molybdate of ammonia or other nitrogenous base to produce a precipitate, heating the precipitate at about 350-650 DEG C. grinding and forming the resulting mass into pellets and heating these at about 500-650 DEG C. Preferably the proportion of both aldehyde and oxygen in the reactants mixture is between 1 and 20% by volume, the remainder being inert diluent e.g. nitrogen, propane, butane, isobutane, carbon dioxide or steam.  In lieu of acrolein or methacrolein compounds yielding these substances under reaction conditions may be used e.g. propylene with molecular oxygen.  The reaction may be effected isothermally or adiabatically in a fixed or fluidised bed. Specification 878,802 also is referred to.

Title: Improvements in or relating to resilient valves for fluids under pressure
IPC: F16K15/14
Filed: 1956-09-12
Abstract: 846,271. Valves. REGIE NATIONALE DES USINES RENAULT. Sept. 12, 1956 [Jan. 24, 1956], No. 27897/56. Class 135. A valve in a line between a distributer and operated apparatus, e.g. a pneumatic jack, which permits the rapid exhaustion of used air from the apparatus, comprises a resilient cup-shaped valve member 29, Fig. 1, having a small hole 36 in its base and slidable in a valve body 21 to co-operate either with a seat 26 (lower half of Figure) on a valve seat member 23 connected to the distributer or with a ring of holes 41 open to the atmosphere and surrounding a connection 22 to the apparatus. On compressed air being admitted to the valve from a remotely disposed distributer the valve member first moves rightwardly so that beads 33, 34 on its bottom are compressed to seal the holes 41. A lip 42 then hinges about an annular groove 37 to fully open the.valve to supply the apparatus. On the piston of the apparatus reaching the end of its stroke the pressures on the two sides of the valve member equalize each other so that the lip resumes its original position, the holes 41 still remaining closed. On movement of the distributer to exhaust position the pressure on the upstream side of the valve member is reduced so that it moves leftwardly and used air is rapidly exhausted through the holes 41 without having to return through the distributer. In a modification, a resilient cupshaped valve member 56, Fig. 4, having a small hole 58 in its base and held by an annular bead 54 between a valve body 44 and a valve seat member 47 is normally seated against the distributer connection 45. On admittance of compressed air to the valve the valve member 56 is first compressed to close a ring of holes 52 opening to the atmosphere and surrounding a bore 48 in the valve seat member 47 connected to the apparatus. A lip, as before, then hinges about an annular groove to fully open the valve. In a further modification, a resilient cup-shaped valve member 60, Fig. 7, having a small hole 71 in its base and held by an annular bead 65 between a valve body 73 and a valve seat member 63 normally closes the outlets from branches 69. On admittance of compressed air to the valve, the valve member 60 is first stretched to close a ring of holes 62 and then, as before, a lip hinges about an annular groove to fully open the valve. Instead of the small bore the bottom of the valve member may be formed with slits.

A rod cluster fuel assembly 2 has bow restraint means each comprising two similar groups of parallel-disposed webs 3 arranged edge-on to coolant flow through the assembly, the webs of one group being orthogonal to the webs of the other group to define a square lattice, the fuel rods 1 of the assembly being located in alternate voids of the lattice. The webs 3 of each group are interconnected by means of transverse slots 4 extending across half their width (Fig. 4), the resulting grids 42 being disposed within box-like support structures 7 divided into four separate regions, each housing a group of fuel rods 1, by means of plates 28. The fuel rods 1 comprise sintered UO 2  pellets 16 enclosed in stainless steel sheaths 17 with end plugs 18. The end plugs 18 are separated from the pellets 16 by sintered Al 2 O 3  plugs 20 and the fuel pellets 16 in the vicinity of the webs 3 are replaced by similar plugs 22. The fuel rods 1 are supported by a grid 23 similar in construction to the grids 42 and disposed in longitudinal slots at right angles to each other in the upper end plugs 18, the grid 23 and plugs 18 being secured together with brazing 31. The lower end plugs are disposed in a grid in a similar manner but are free to move longitudinally to allow for thermal expansion. In a modification (Fig. 6A), the webs 3 of one group are disposed in a plane close to but spaced from the webs 3 of the other group forming a bow restraint means, each fuel rod 1 being in contact with only one web 3 in each plane. The invention is described with particular reference to an organic liquid cooled and moderated reactor in which a number of the above-described assemblies are incorporated.
