Filed: 1970-03-24
Abstract: 1302600 Casting composite articles SOC INDUSTRIELLE DE COMBUSTIBLE NUCLEAIRE 24 March 1970 [31 March 1969] 14332/70 Heading B3F [Also in Divisions B1 and C7] A composite alloy with no residual porosity, comprising a metal or alloy matrix (e.g. Mg, Al, U, Fe, Ni, Cr, Co or mixtures or alloys thereof) in which are completely homogeneously dis. persed particles or monocrystalline filaments which are insoluble in the solid or liquid matrix and are perfectly bonded therein, is made by fluidizing the additive with a stream of preheated gas neutral to the additive and the matrix, introducing the fluidized material into the matrix melt so that it has a wetting angle of no more than 90 degrees, stirring the treated matrix material and then degasifying it. The additive may be one or more of Al 2 O 3 , BeO, CaO, CeO 2 , TiO 2 , MgO, ThO 2 , UO 2 , ZrO 2 , carbides of B, Hf, Nb, Si, Ta, Ti, W, Zr or ZrC 4 TaC, nitrides of Al, B, Ta, Ti, U or Zr, borides of Ce, Hf, Nb, Ta, Ti or Zr, or B, Be, C, Mo or W; the preferred particle size being 100 Š to 10 Á; and the preferred content of the final alloy being 5-20% by volume of the matrix. The melt produced may be continuously cast under vacuum as described in Specification 1,293,939. In the embodiment shown in Fig. 5 the melt is pumped through a pipe 60 and into a mould 69 via a distributer 68 the nozzle of which is provided with three grooves to ensure lamellar flow. The level of metal in the mould is sensed by a detector 76 which is linked to an electromagnetic pump 75 via a servomechanism 80. When casting non- continuously the metal is cooled rapidly by the use of moulds cooled with water, liquid Na or K or inert gas.

Patent GB-472342-A (GB)
Title: Improvements in or relating to the cleaning and degreasing of materials
IPC: C23G5/02
Filed: 1936-05-22
Abstract: <PICT:0472342/III/1> Materials are cleaned in the presence of a water-emulsion of a soap or soap-like compound by treatment with a water-insoluble volatile organic solvent in the presence of an addition agent having an appreciable vapour pressure at the boiling point of the solvent and soluble therein but having at most a slight solubility in water, the said agent having the property of facilitating the dispersion of the said water-emulsion in the solvent.  The process is applicable to the cleaning of machined metal parts which have been lubricated with aqueous emulsions.  As solvents there may be used chlorinated aliphatic hydrocarbons, e.g. trichlorethylene, perchlorethylene; and as addition agents one or more hydrogenated p  cyclic hydrocarbons or hydrogenated phenols, e.g. cyclohexanol, methyl cyclohexanol, tetrahydronaphthalene.  The materials may be immersed in boiling solvent and then in the solvent vapour, for instance in apparatus described in Specifications 391,454 and 400,997.  As shown in the Figure, articles to be cleaned, such as machined screws, are put into the part L and solvent and addition agent into the parts L and L<1> of the apparatus.  Owing to the presence of the soap on the machined articles and the additive agent in the solvent, the water on the articles is dispersed in the solvent.  On heating, water, solvent, and addition agent are vapourized, condensed by the coil C and run into the separator S. In the absence of any soap, the water separates.  Solvent and addition agent return to the bottom of L, liquid, dirt, and soap being displaced over the weir into L<1>.

Title: Improvements relating to mouldable compositions and to methods of making the same
IPC: C08L97/02
Filed: 1943-09-09
Abstract: Resin-containing sawdust, waste wood and the like is heated in water with a hydroxide of an alkaline earth metal and evaporated to dryness to obtain a powder which can be moulded at a relatively low pressure and temperature.  An additional thermoplastic or thermosetting material such as phenol aldehyde, urea formaldehyde, or polyvinyl resin, cellulose acetate, bitumen, pitch, glue, casein, or rubber may be added to the sawdust as a solution or emulsion before evaporation of the water.  The sawdust may be swelled before treatment, for example, by the addition of calcium thiocyanate.  Additional substances, such as hardening agents, plasticisers, weighting, colouring or preserving agents may also be added.  Numerous examples are given of which the following is typical:- 100 parts by weight of oak sawdust and 100 parts of fir sawdust are mixed with 100 parts of water containing 5 parts of calcium thiocyanate and allowed to stand for 12 hours.  4 parts of calcium oxide in 80 parts of water are added and the mixture is heated.  To this is added 10 parts of glue in 100 parts of water containing 2 parts of linseed oil and 2 per cent of cobalt resinate.  After boiling 5 parts of copper sulphate in 100 parts of water containing 40 parts of formaldehyde are added. The mass is evaporated to dryness and moulded at 150 DEG  C. for 30 mins. at a pressure of 800-1400 lbs. per sq. in.

Patent GB-893276-A (GB)
Title: Method for nitrating cellulose
IPC: C08B5/02
Filed: 1958-05-09
Abstract: Cellulose is nitrated by means of a mixture of nitric acid and an incompletely chlorinated aliphatic hydrocarbon, e.g. methylene chloride or chloroform, and the spent mixture is regenerated after the nitration by contact with a sulphuric-nitric acid mixture and is then reused in the nitration process.  Before the nitrating step the nitrating mixture may be passed over an alkali or alkaline-earth metal nitrate, e.g. pulverulent sodium nitrate, to remove any sulphuric acid in the mixture.  After nitration the nitrocellulose may be compressed or drained, set under water, and the incompletely chlorinated aliphatic hydrocarbon carried along with the nitrocellulose may be recovered by distillation and then either recycled into the circuit feeding the mixture in completely chlorinated aliphatic hydrocarbon and nitric acid, or added to the drained nitrocellulose, which is then subjected to a second draining to reduce the losses of nitric acid carried along with the nitrocellulose.
