Title: Improvements in the manufacture and production of oxides of nitrogen
IPC: C01B21/20
Filed: 1937-06-08
Abstract: Concentrated oxides of nitrogen are obtained by reducing vaporized aqueous nitric acid or mixtures of nitrous gases with water vapour with gases rich in combustible hydrogen, e.g. hydrogen, hydrogen sulphide, methane, illuminating gas, &c., preferably at temperatures of 150-750 DEG  C. at any desired pressure.  Catalysts, e.g. platinum, oxides of manganese, bismuth, iron, chromium or vanadium, bauxite, aluminium oxide gel, silica gel, zeolites or bleaching earths may be used.  When using hydrogen sulphide, substantially all the sulphur is converted into sulphuric acid which may be recovered in concentrated form by precipitation in stages.  The heat evolved may be used for the vaporization and decomposition of the aqueous nitric acid to be treated.  Examples describe the reduction with hydrogen, methane, illuminating gas and hydrogen sulphide at varying temperatures and using catalysts such as a mixture of manganese, bismuth and iron oxides, quartz, or pumice impregnated with vanadic acid.  The amounts of reducing gases are preferably chosen to obtain a final product having a composition between nitric oxide and nitrogen peroxide.

Title: Improvements in or relating to compositions of matter and moulding mixtures prepared therefrom
IPC: C08L61/10
Filed: 1930-05-24
Abstract: Phenol-aldehyde condensation products are made by heating a non-reactive or permanently fusible phenol-aldehyde condensation product with a neutralizing agent in solid condition, e.g. a basic oxide or hydroxide such as lime or a carbonate such as of magnesium, iron, zinc, sodium, or potassium.  Sufficient amount of the agent to neutralize all free phenol is added and the heating continued till the phenolate is formed or an amount sufficient to combine with the hydroxyl groups of the resin molecule in addition may be added.  The products have improved moulding properties, and moulding compounds may be produced without plasticizing the compound on the differential rolls.  Asbestos may be successfully incorporated yielding a fireproof product.  In an example, calcium hydroxide is boiled with a mass containing the resin and free phenol (1,25 phenolic groups to each methylene), cooled and heated with hexamethylenetetramine (paraformaldehyde, trioxymethylene, furfural, or anhydro-formaldehydeaniline) to convert to the infusible state; the pulverized product is incorporated with a fibrous filler and may be moulded in a hot press.  Fats, waxes, resins, casein, pigments, &c., or a small amount of a plasticizing agent, e.g. creosote oil or furfural may be added if desired.  Another example is given in which the hydroxyl groups of the resin molecule are also reacted with lime. Specifications 128,477 and 326,545, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Tool for straightening or bending metal wire, tube, bar and the like
IPC: B21F1/02
Filed: 1940-11-15
Abstract: 545,220. Angular bending; straightening. THOMAS, N. H., and LONDON PASSENGER TRANSPORT BOARD. Nov. 15, 1940, No. 16519. [Class 83 (iv)] A tool for bending or straightening wire, tubes, bars &c. particularly for bending in situ local bends caused in overhead traction wires by trolley heads upon dewirement, comprising a carrier mounting a top pressure roll and bottom pressure members and provided with a means for driving it along the wire &c. to bend the same by a rolling action, has the roller adjustably mounted in a support which is readily displaced from its working position so that the tool may be applied at any point of a long wire. The carrier consists of a pair of side frame members each comprising a pair of plates 1, 2, the plates 1 mounting a pair of rollers 7 and the plates 2 being slotted at 16 to receive a slide 20 carrying an adjustable top roller 5. The roller 5 engages one side of the wire &c. whereas the rollers 7 may engage the wire either directly or through an intermediate bar 8 which has a rack 9 on its underside along which the carrier is traversed by a pinion 11 operated by handles 13. The upper side of the bar may be inclined from opposite ends and be provided with a central recess 14 so that as the carrier is traversed backwards and forwards along the rack with adjustment of the roller 5 by the screw 6, the upward deformation in the wire may be bent past the straight position to allow for its elastic recovery on release. The bar has end stops 31 and is provided at one or both ends with slotted work clamping hooks 26 which are adjusted by screws 29 and may be swung about pins 27 so that the apparatus may be brought up against the wire. For this purpose also the roller 5 and its mounting may be removed from the slot 16. In order to effect this the adjusting screw 6 passes through a cross bar 22 carrying hooks 23 which are normally held by pins 18 engaging between the hooks and projections 17 on the plates 2, the pins being connected by springs 24. In order to remove the slide &c. the screw 6 is slackened off and the pins 18 drawn apart, then taken over the projections 17 and then placed in the recesses 25 in the hooks. For operating on a traction line close to its support the roller 5 may be mounted near one end of a carrier. Curving may be effected by varying the form of the bar 8. To avoid removing the upper roller 5 for application of the apparatus to the wire the carrier may be made in two parts hinged together. According to the Provisional Specification the rollers may be coupled by gear wheels or chain drive to traverse the carrier along the wire.
