Title: Method of producing ferro-nickel or metallic nickel
IPC: C22B23/02
Filed: 1970-05-28
Abstract: 1309927 Reducing nickel/iron ores NIPPON YAKIN KOGYO K K 28 May 1970 [2 Feb 1970 9 Feb 1970] 25683/70 Heading C7D [Also in Division C1] Ferro-nickel is produced from Fe-rich Nicontaining materials by mixing with SiO 2  and reducing in an atmosphere having a CO/CO + CO 2  ratio of 1À6-90% at a temperature sufficient to form fayalite (Fe 2 SiO 4 ) whereby reduction of Fe is suppressed. The Nicontaining material may be laterite, garnierite, or Fe rich Ni oxide. The SiO 2  source may be pure SiO 2  or may be derived from a Ni Mg silicate ore e.g. garnierite by crushing to <150 microns, calcining at 500-800‹C., adding water to form a slurry, blowing CO 2  through the slurry at a pp of 1-20 atm and at 20-50‹C., and filtering to give a SiO 2  - containing residue. The CO/CO 2  atmosphere may be obtained using coke, coal, hydrocarbon gas or CO as reducing agent, and argon may also be present. The mixture of fayalite and ferro-nickel may be separated by crushing and magnetic separation.

Title: Improvements relating to the ventilation of dynamo-electric machines
IPC: H02K9/06
Filed: 1920-09-07
Abstract: 172,703. Field, A. B., and Metropolitan- Vichers Electrical Co., Ltd. Sept. 7, 1920. Armatures and field magnets, cooling and ventilating.-For ventilating a dynamo, a fan 17 is used on the rotor together with a stationary end bell 20 provided with partitions so arranged as to form a chamber to which air is sucked from atmosphere by the fan, and a second chamber 29 into which the air is delivered by the fan and from which it passes to ventilate passages 14, 15 in the stator, to the air gap 12, and through a bypass 32 into a third chamber 30 from which it passes to passages 8 in the rotor through an annular outlet 17 of smaller radius than that of the fan. The end bell 20, which is shown in inside elevation in Fig. 2, has double walls 21, 22 merging together at the outer edge and enclosing the inlet chamber 25. The inner wall has a coned part 23 brought close to a ring 18 inside the fan 17 so as to define the annular suction inlet 27 of the fan. Part of the air is delivered from the chamber 29 to the air-gap and statorducts 14, 15 and part passes through a radial by-pass 32 in the end bell, defined by a passagethrough the chamber 25, to a chamber 30 around' the shaft. This chamber at one end is closed by a cover 31 and at the other it directs the air into axial ducts 10 in the rotor and thence, byradial ducts 11, into the air gap. The supply to the rotor ducts 10 is at substantially the same pressure as that of the air-gap so that the pressure added by the centrifugal action of the rotor ensures free ventilation of the rotor.

The organic polyhydroxyl compound used as starting material is most preferably a polyester or polyether conventionally used in the polyurethane art. Preferred anhydrides used in (a) are organic dicarboxylic acid anhydrides, e.g. phthalic acid anhydride and maleic acid anhydride, and the neutralizing agent may be an inorganic or organic base. Alternative process (b) is particularly preferred, especially when the reactant is the reaction product of a monohydroxypolyalkylene oxide, containing a major amount of ethylene oxide units, and a polyisocyanate at an NCO/OH ratio of 1À2 : 1 to 2À2 : 1. The compounds used in alternative process (c) may be monoisocyanates which contain tertiary amino groups or sulphonic acid groups. The modified polyhydroxyl compounds, apart from being water-soluble or dispersible, may also be suitable as dispersing agent for unmodified polyhydroxyl compounds.

Title: Improvements in or relating to varnished cambric
IPC: H01B3/18
Filed: 1936-09-24
Abstract: Insulating-material of the varnished cambric type comprises a textile base having a primer coat of a varnish containing a resinous esterified reaction product of an aromatic hydroxycarboxylic acid and an aldehyde, and one or more body coats of a varnish containing an inherently oil-soluble alkyl- or aryl-substituted phenol-aldehyde resin.  The outermost coat may contain a wax such as ceresin, carnauba or paraffin wax, or halogenated naphthalene.  The fabric is sized and/or calendered before application of the varnish by dipping, spraying or brushing.  Each coat of varnish is preferably baked on before the next is applied.  Additional coat of a varnish containing an oil-modified alkyd resin may be applied or such a resin may be mixed with one of the other resins.  The resin for the primer coat is made by reacting together a polyhydric alcohol such as glycerol, ethylene glycol or pentaerythritol, a natural resin or resin acid such as abietic acid, rosin, copal or sandarac, and a potentially reactive reaction product of an aromatic hydroxy carboxylic acid such as p-hydroxy benzoic acid, cresotinic acid or hydroxy naphthoic acid and a methylene-containing agent such as formaldehyde, hexamethylenetetramine and acetone.  This resin is bodied with fatty oils such as linseed, tung, soya bean, perilla or fish oils, by heating, and diluted with a hydrocarbon with addition of a drier such as a mixture of lead, cobalt and manganese naphthenates.  The resin for the body coat is made by reacting an aldehyde with p-phenyl-phenol, dicresol, dithymol, cresol, xylenol, or butyl-, amyl-, or benzyl-phenol, and is bodied with oil and thinned as in the case of the primer coat.  Blends of the resin varnishes described may be used for the primer and intermediate coats.  Specification 471,927 is referred to.

The connection between the surfaces h and S is a horizontal surface n, and additional guiding surfaces in the form of projection t1, t2 may be provided on the projection Vo. The surface S is stepped to form a projection N and a recess A, Fig. 3b, which interlock with corresponding surfaces on the opposing coupler, and transmit, when the couplers are locked, a portion of the tractive effort. A locking bolt B, Fig. 3<b>. is housed in each coupler head and a recess F for the head of the opposing coupler bolt is made in a lug D on the side of the coupler opposite the bolt B. The guiding surfaces may be increased, as shown in front and side elevation Figs. 4a, 4<c> respectively, by tapering the underside of the projection Vc, by a surface f1 and making a corresponding inclined surface f2 in place of the horizontal surface n. The surface l of the projection Vu may be reduced to one-half as shown in Fig. 4<a>, without impairing its guiding capacity and in a modification both surfaces h and l may be reduced as shown in dotted lines at h1, l1, so that it takes the form of a projecting bar. In this case the surface S is not reduced by the surfaces f1, f2 but has an equivalent guiding surface projecting from the lower end of the projection Vo. Specification 244,588 also is referred to.

[Also in Division G5] An acoustic element for absorbing sound comprises a sandwich structure of two or more sheets of porous concrete or cement with a non- cellular intermediate reinforcing membrane between two adjacent concrete or cement sheets which permits transmission of sound between these sheets. The cement may be a portland, alumina or silicate cement to which sand aggregate may be added to form a concrete. The concrete or cement may be made porous by chemical action, by addition of a foam or foaming agent, by liberation of steam in the wet mixture or by the use of a cellular aggregate such as exfoliated vermiculite, expanded perlite or clay, or sintered fuel ash. The concrete may contain additives such as P.V.C., water-soluble epoxides or natural or butadiene/styrene rubber latices. The reinforcing membrane may be an open-weave fabric, metal wire mesh, bonded non-woven fibrous material or continuous film and may be secured to the concrete or cement sheet by an epoxy, phenolformaldehyde, ureaformaldehyde, polyurethane, polyvinyl acetate, polyvinyl ether, or natural or synthetic rubber adhesive. A reinforcing membrane may also be positioned in the middle of one of the concrete or cement sheets. A backing membrane of asbestos, cement, metal sheet or resin-bonded fibrous material may be secured to a surface of the element. The element may contain absorption cavities and the concrete sheets may be perforated. It may be recessed to facilitate attachement to a metal frame for suspension or may be secured to walls or ceilings by means of adhesive or screws.
