Patent GB-913637-A (GB)
Title: Metal casting process
IPC: B22C9/04
Filed: 1959-01-05
Abstract: A metal casting process comprises building up several stucco and dip coats of finely divided ceramic material on a disposable pattern, adding a final coating containing an inorganic material with a lower maturing temperature, heating the mould to dispose of the pattern, and finally pouring the metal.  A cluster of wax patterns is first dipped and rotated in a composition consisting of colloidal silica zircon, water and sodium fluoride.  The cluster is then allowed to drain in various positions, air pockets being removed by a stream of air.  While the cluster is moved about, it is then coated with alundum following through a screen from a vibratory feeder.  The cluster is dried and dipped a second time and coated with a coarser alundum stucco coat.  After a further dipping, a tabular alumina coating is applied, and further coatings up to ten may be applied. One or more dips are then made in a composition containing feldspar, in addition to colloidal silica, zircon, water and sodium fluoride, with subsequent stucco coating.  The mould is then dried in a dehumidified atmosphere. The face of the mould is ground flat to enable the metal to be poured by inversion and it is then fired at 1800 DEG F. at 3-30 mins. while allowing the patterns to flow out.  A further eutectic coating containing feldspar is then added.  The mould is finally pre-heated to 1600-2200 DEG F. clamped to the furnace, inverted and filled.  The filling may take place under pressure and/or under a protective atmosphere.  It may be cooled in a controlled atmosphere while surrounded with insulating material.  The zircon in the dip may be replaced by flours of alumina, titania, silica, stabilized zircon, fused quartz, thoria, chromite, sillimanite, mullite, magnesia or glass.  The mould may be wetted before each dip.  The alundum stucco coat may be replaced by zircon, sillimanite, mullite, glass, thoria, chromite or magnesia.  The eutectic feldspar vitrifies at 1000-2200 DEG F. and seals the mould pores.  The feldspar coating may be an intermediate rather than an outside coating.  The feldspar may be replaced by iron oxide, borax or stannous chloride.  Specification 913,638 and U.S.A. Specifications 2,380,945, 2,439,207, 2,441,695, 2,521,839 and 2,806,271 are referred to.

Title: Improvements in or relating to insulating oils
IPC: H01B3/22
Filed: 1932-01-09
Abstract: Insulating-oils are obtained by separating petroleum oils into a number of fractions by extraction with nitrobenzene, removing the nitrobenzene, treating one or more of the fractions with fuller's earth, subjecting them to a resistivity-stability test and selecting those showing substantial stability or even increased resistivity. In an example, 100 litres of a pipe still residuum that has been purified by sulphuric acid and contact with clay, is heated to complete miscibility with 50 litres of nitrobenzene; the mixture is cooled to 10 DEG  C. and allowed to settle, and the fractions separately decanted and freed from nitrobenzene by vacuum distillation.  The 80.7 litres of undissolved oil are similarly treated with 75 litres of nitrobenzene, and the 63 litres still undissolved treated with 150 litres of nitrobenzene, leaving 30.7 litres of undissolved oil. The fractions are percolated through fuller's earth at 70 DEG  C. and then submitted to the oxidation test described below; the undissolved fraction is increased in resistivity from 5.52 to 28.4.  The test consists of placing 100 gm. of the oil in a 250-330 cc. Erlenmeyer flask closed by a perforated or slotted cork stopper, immersing in an oil-bath at 100 DEG  C. for 72 hours and measuring the resistivity before and after.
