Title: Improvements relating to heating arrangements for spinneret headings
IPC: D01D4/00
Filed: 1951-11-29
Abstract: <PICT:0700728/IV(a)/1> <PICT:0700728/IV(a)/2> A heating arrangement for a spinning-nozzle head comprises a body member detachably connected to a spinneret support and provided with a longitudinal duct having its side walls adapted for substantial alignment with the side walls of the spinneret, a hollow heating unit substantially centrally positioned in the duct, this heating unit having a bottom wall joined to the side walls and having a baffle positioned longitudinally therein with its lower end spaced from the bottom wall, means for circulating a hot fluid through the hollow heating unit, and means for introducing spinning-solution into a passageway surrounding at least a substantial portion of the heating unit.  If desired, the longitudinal duct and the heating unit may be of circular or similar cross-section so that they each have a single continuous side wall.  The apparatus may be used in dry or wet spinning operations and in particular in the extrusion of solutions of acrylonitrile polymers in hot concentrated aqueous solutions of sodium or calcium thiocyanate into aqueous coagulating liquids maintained at a temperature not exceeding +10 DEG C., e.g. -15 DEG to +5 DEG C.  As shown in Fig. 1, the spinneret 10 is supported by a coupling 14 which is screwed on to the body member 12 of the spinning-head.  A hollow heating-member 32 is supported within the duct 28 of member 12 by means of the screwed head 56.  A baffle 38 extends longitudinally from the top of member 32 but its lower end 40 is spaced from the bottom wall 34.  Heating fluid enters through conduit 44, passes down the member 32 and then under the baffle 38 and upwardly to the outlet conduit 46.  Spinning solution enters the spinning head through conduit 48 and passes through the annular space between the heating member 32 and the inner wall of member 12 to the spinneret 10.  An alternative arrangement for securing the heating-member 32 is shown in Fig. 4. p  A threaded-member 62 is screwed into the coupling 64 so that the gasket 66 is pressed against the sides or continuous side of the member 32 which is thus held securely in the desired central position in the duct 28. Specification 672,775 is referred to.

Abstract: 1,105,685. Coating apparatus. BIRD & SON Inc. 23 June, 1966 [2 July, 1965], No. 28158/66. Heading B2L. [Also in Division F2] Tube forming and coating apparatus comprises a stationary canti-lever arbor 16, an endless belt 20, Fig. 2 (not shown), for continuously helically winding one or more paper webs 14 with abutting or overlapping side edges about the arbor to form a tube 12 and to advance said tube beyond the free end of the arbor, and tube-coating means 10 mounted on said arbor free end for interiorly coating the tube as it advances. The tube-coating means includes an inflatable doctor or wiper 28 that is mounted on a hub 40 secured to the arbor end and is spaced from said end to define a reservoir 30. Coating material, such as plastics, is fed by a pump 58, which includes filter means, through a conduit 56 extending through the arbor into a circumferential groove 34 in an application ring 26, and then passed the periphery of the ring flange 38 to the reservoir. Return flow conduits 60, 62 are also provided. Thus coating material in the reservoir is both maintained in contact with the tube inner surface and recirculated through filter means. The application ring is not essential and may be dispensed with. A conduit 64 supplies pressurised air under control of valves 66, 68 to inflate the wiper to the desired pressure and thereby control the thickness of the coating. A further conduit 72 supplies a stream of drying air, which may be preheated, to the interior of the coated tube.

Patent GB-1116378-A (GB)
Title: Alcohol hydrogenolysis
Inventor: KHOOBIAR SARGIS
IPC: B01J23/00
Filed: 1965-07-05
Abstract: Alcohols are converted to hydrocarbons by reaction with hydrogen in the presence of a catalyst comprising (a) ZnO and/or one or more of Cu, Co, Ni, Ag and Sn essentially in free metal form with or without a minor amount in the form of an oxide thereof, and (b) an oxide of Fe or Cr or mixtures thereof, the weight ratio of a: b being from 3: 7 to 20: 1 (calculated as the lowest valency state oxide), the catalyst being supported on a carrier containing 2-15% of a basic material selected from alkali metal and alkaline earth metal oxides and hydroxides. The reaction is preferably effected at 150-500 DEG C. with a hydrogen: alcohol ratio of at least 1: 1.  Particular application of the process is to hydrogenolysis of aryl carboamides, e.g. cumyl alcohol to yield cumene.  Reference is also made to the production of aralkanes from benzyl alcohol and methyl phenyl carbinol.  The process may be subordinate to the epoxidation of olefins using the hydroperoxides of ethyl-benzene, cumene, p-ethyltoluene, isobutylbenzene, tetralin, diisopropylbenzene, p-isopropyltoluene and phenylcyclohexane.ALSO:Epoxides are made by a process in which an alkyl aromatic compound having at least one hydrogen atom on a carbon adjacent to the aromatic ring (preferably cumene or ethylbenzene) is first converted to a hydroperoxide, which is then used to epoxide an olefin, being itself converted to an aryl carbinol.  Examples describe the epoxidation of propylene by cumene hydroperoxide with or without a solvent. Cumyl alcohol is a by-product and the epoxide is separated by distillation.  Cumene hydroperoxide is prepared by passing O2 into agitated cumene at 130 DEG  C. containing tert.-butyl perbenzoate as initiator.ALSO:A hydrogenolysis catalyst comprises (a) ZnO and/or one or more of Cn, Co, Ni, Ag and Su essentially in free metal form with or without a minor amount in the form of an oxide thereof, and (b) an oxide of iron or chromium or mixtures thereof, the weight ratio of (a):(b) being from 3:7 to 20:1 (calculated as the lowest valence state oxide), the catalyst being supported on a carrier containing 2-15% of a basic material selected from alkali metal- and alkaline earth metal-oxides and hydroxides. Conventional preparative details are disclosed, e.g. mixing salts of metals, impregnating calcining and reducing.  The catalysts may be supported on Al2O3, SiO2, clays, amorphous zeolites and molecular sieves, preferably of 4 to 40 mesh. Especially suitable is g -Al2O3 of surface area 150-300m2/gm. Examples of catalysts include (1) actuated Al2O3 100 parts .Cr2O3.1-20 parts .NiO.3-20 parts .KOH.2-12 parts BaO is another specified basic material for incorporation in the carrier.

Title: Improvements relating to neutron-absorbing bodies for use in nuclear reactors
Inventor: WORN DAVID KENNETH
IPC: G21F1/02
Filed: 1956-09-17
Abstract: A solid neutron-absorbing body is made by powder-metallurgical methods and comprises a discrete phase dispersed in a matrix, the discrete phase being composed of particles of a neutron-absorbing element (in elemental or combined form) that are large enough to be retained on a 200 mesh B.S.S. screen, but preferably should pass through a 60 mesh screen, and both the matrix and the discrete phase being stable up to 900 DEG C.  The matrix may be of copper and the discrete phase boron carbide, titanium boride or zirconium boride, or the matrix may be nickel or iron and the discrete phase gadolinium oxide or europium oxide.  In one example 15% by weight of boron carbide powder is mixed with electrolytic copper powder, compacted, sintered for half an hour at 900 DEG C. in a hydrogen atmosphere, and reduced in thickness by 50% by cold rolling.  The body may be provided with a covering or stainless steel or other corrosion-resistant alloy and used as a control rod for a nuclear reactor or as a shield for auxiliary equipment associated with a reactor.
