Title: An improved process for treating aluminium and its alloys
IPC: C22B21/06
Filed: 1930-09-08
Abstract: 366,545. Aluminium and aluminium alloys. ROSENHAIN, W. and GROGAN, J. D., National Physical Laboratory, Teddington, Middlesex. Sept. 8, 1930, No. 26730. [Class 82 (i).] Aluminium and aluminium alloys are improved by introducing into the molten metal one or more of the chlorides of silicon, carbon, titanium or aluminium. The chlorides may be passed from a funnel 1 into the metal contained in a crucible 5 in the manner shown in the Figure, whilst large quantities of metal may be treated in a vessel resembling a Bessemer converter. Solid aluminium chloride may be placed on the surface of the metal and forced down by a plunger or other device. The chlorides may also be volatilized into a stream of inert gas e.g. nitrogen, argon, helium, hydrocarbons or other halogen compounds, and be carried by the stream into the metal. Titanium may be introduced into the metal when titanium chloride is used. Amongst other effects produced the treatment according to the invention reduces the grain size in the metal.
Patent GB-687745-A (GB)
Title: Improvements in or relating to the production of aldehydes and ketones
IPC: C07C45/00
Filed: 1950-11-02
Abstract: Aldehydes or ketones are produced by the dehydrogenation of primary or secondary alcohols by passing the vapour of a saturated primary or secondary alcohol over a dehydrogenation catalyst at a temperature of from 200 DEG  to 300 DEG  C. and at a pressure below 300 mm. Hg. Suitable alcohols to use as starting materials are, for example, ethyl alcohol, butyl alcohol, 2-ethylhexyl alcohol, isopropyl alcohol, secondary butyl alcohol, methyl isobutyl carbinol, cyclohexanol, methyl cyclohexanol, phenyl-ethyl alcohol and guaniol. Any dehydrogenation catalyst may be used.  The preferred catalyst is reduced copper deposited on a carrier, preferably kieselguhr, in association with another metal or a metallic oxide if desired.  In the examples (a) ethyl alcohol is converted into acetaldehyde with some acetic acid and ethyl acetate as by-products; (b) isopropyl alcohol is converted into acetone; (c) ethylhexyl alcohol is converted into ethylhexaldehyde; and (d) cyclohexanol is converted into cyclohexanone.  Specifications 636,743 and 636,800 are referred to.

Title: Improvements in or relating to adhesives for securing non-metallic friction materialto the metallic backings of friction elements
IPC: C09J109/00
Filed: 1947-10-06
Abstract: Non-metallic friction facings are secured to metallic backings or brake shoes by a dry, flexible film containing, in cured condition, 100 parts by weight of a butadiene-acrylonitrile type copolymer and 75-500 parts of a phenolic resin, the copolymer containing 10-75 per cent of nitrile and the remainder butadiene. Instead of butadiene, derivatives such as isoprene, 1 - methyl - 1,3 - butadiene, 2,3 - dimethyl butadiene and chloroprene, may be used.  Suitable nitriles are acrylonitrile, methacrylonitrile, ethacrylonitrile, propyl- and chloro-acrylonitriles.  The copolymers are preferably those having a high sol content.  Drying of the copolymers before milling is preferably avoided.  For the phenolic resin specified phenols are phenol, o-, m- and p-cresols, xylenols, resorcinol, naphthols, o-ethyl phenol, carvacrol and salicylic acid.  Suitable aldehydes are formaldehyde, acetaldehyde, propionaldehyde and benzaldehyde.  The resins may be modified by oils and alkyd resins.  If hexamethylene tetramine is incorporated, the resin should be heat-treated, but not beyond the fusible stage, before milling.  Compounding may be effected on any mill with the addition of curing agents, e.g. sulphur, preferably together with accelerators such as benzothiazyl disulphide, thiuram polysulphides, mercaptothiazoles, guanidines, aldehyde-amines, zinc oxide and litharge, for the copolymer and hexamethylene tetramine for the phenolic resin.  The composition may be calendered or cast from solution into films which are sandwiched between the friction facing and the backing and cured at a temperature between about 325 DEG  and 400 DEG  F.  Specification 519,730 is referred to.

Patent GB-1012928-A (GB)
Title: Ion-exchange process
IPC: C13B20/14
Filed: 1962-07-12
Abstract: Bicarbonate salts of primary, secondary and tertiary amines and mixtures thereof having molecular weights above 185 are used in water-immiscible solutions, such as benzene, to extract anions from aqueous solution into the non-aqueous phase and to replace them by bicarbonate ions. The amines may be recovered by subsequent treatment with carbon dioxide.ALSO:Brackish water is passed downwardly through a bed of weakly basic anion-exchange resin in the bicarbonate form and upwardly through a cation-exchange in the weak acid form.  Carbon dioxide is removed from the treated water by a vacuum unit.  This carbon dioxide ion solution is utilized to regenerate both the exchangers.  The regeneration of the anion exchanger is carried out at elevated temperatures.

Title: Improvements in or relating to methods of making hollow bodies from fibrous materialand heat-hardenable resin
Inventor: POLLARD HAROLD JOHN
IPC: F16S3/00
Filed: 1954-09-23
Abstract: 781,925. Moulding hollow fibre-resin articles. BRISTOL AIRCRAFT, Ltd. Sept. 9, 1955 [Sept. 23, 1954], No. 27577/54. Class 87(2). A method of making a tubular body comprises (i) covering a former with an impervious membrane, (ii) placing on the membrane a coating of fibrous material impregnated with thermosetting resin, (iii) placing the coated former in a mould and sealing the membrane to the mould so as to enclose a space between it and the mould containing the resin-impregnated fibrous material, (iv) evacuating the space so as to lift the material from the former and apply it to the internal mould surface, (v) placing the coated mould in a closed vessel, (vi) increasing the presence and temperature in the vessel to cure the resin while maintaining evacuation of the space between the membrane and the mould (vii) removing the mould from the vessel and removing the moulded article from the mould. The fibre is preferably asbestos felt and the resin a water soluble phenol-formaldehyde resin. Since it takes longer to place the coating on the former than it does to cure the resin two or more formers may be used with each mould. The mould and former may be recessed to receive extra layers of material for local thickening. The internal surface of the twopart mould 14, 15, Fig. 5, is shaped to give steps in the wall of the moulded article, Fig. 6, and is recessed at 22, Fig. 4, to thicken the wall where fittings are to pass through, and has a block 78 to form a recess in the face of the moulded article. The mould halves are flanged and the flanges have outer grooves 27 for rubber sealing strips and inner grooves 23, stopping short of the ends, connected through holes 26 with piping 25 which may be connected to a vacuum pump. The flanges 16 of one mould half have tapped holes 30 for screws which bear on the flanges of the other mould half, to assist in opening the mould. The former comprises three sheet metal sections 35, Fig. 3, with bentin edges, each section subtending an angle rather less than 120‹, which are bolted through interposed glass fibre and resin L-sectioned stiffeners 39, to end discs 36. Gaps 43 between the sections enable the former to be contracted when the discs 36 are removed or the sections moved inwards are allowed by slots in the discs. Steps are formed inside the moulding by glass fibre and resin rings 35 placed as shown in Fig. 6. The former has trunnions and can be rotated in a suitable support for convenience in applying fibrous-resin coating. The membrane is conveniently an open-ended tubular polyvinyl chloride bag 54, Fig. 6, into which the former is slipped and on which the layers of resinimpregnated asbestos felt are laid, slightly overlapping and tacked to one another by local heating so they do not fall off as the former is rotated. After coating the inside of the mould with a release agent, e.g. zinc stearate or silicone, pre-cut felt 57 is placed in

The cooling chamber 4 shown is mounted on a frame 3 running on roller tracks 2a, 2b and has its vertical side walls composed of hollow metal elements 6a, 6b, 6d bolted to channel irons 8 and connected by conduits 6m so that the cooling fluid supplied by a conduit 9a ascends in vertical columns. Cooling fluid is also supplied by conduits 9b, 9d to the lower, front, and upper walls. The heated cooling fluid is discharged through a conduit 10 either into a gutter arranged along one of the roller tracks or into a. heat exchanger or other heat-utilizing device. The cooling chamber is charged through an opening 11 which is then suitably closed.
