Title: Electrostatic signalling device
Inventor: AIKEN WILLIAM ROSS
IPC: G09F9/37
Filed: 1967-05-24
Abstract: 1,137,299. Electrostatically controlled indicators. ELECTRONIX-TEN Inc. 24 May, 1967, No. 24084/67. Heading G5C. [Also in Division G1] An indicator device having a vane 12 (which may constitute one of the elements of a monogrammic sign) rotatable about an axis 16 includes, adjacent the path traced out by the edge of the vane remote from its axis, an electrode, e.g. 32 of such arched configuration that, as the vane rotates under the influence of the field between the vane edge and the electrode, said field increases in strength. It is stated that this arrangement permits angular displacement of the vane through more than 90 degrees without the use of very large potentials. As described (Fig. 4), a vane 12 hinged at 16 to a base 10 is attracted by the field set up by an electrode 32. In the position of vane 12 shown in phantom the field is strongest; this is achieved by two methods: (i) the edge 34 of electrode 32 approaches nearest to the path of the vane; (ii) the width of electrode 32 is greater at 34 than at 36. These two principles may be applied independently (see Figs. 1 and 2-3, not shown). In other embodiments, two electrodes may be used, one to displace the vane from rest, the other to return it positively. In each case, either of the above two principles may be utilized. Thus (see Fig. 9) an attractive potential applied to electrode 58 displaces vane 56 to the position shown in solid lines; if applied to electrode 60, the vane returns. See also Figs. 5-6, 7-8, 13-14, 16 (not shown) and 18. The vane may pivot about axes located otherwise than at its edge, Figs. 17 (not shown), and 18. A monogrammic sign is described wherein opposite faces of the vane are painted in contrasting colours. The vane is visible through a window, e.g. 130, Fig. 18. Seven such vanes arranged as a figure " 8 " provide digits from 0 to 9 (see Fig. 15, not shown). Fig. 18 also shows a bar electrode 142: when it is subjected to an attractive potential, vane 134 swings to a position such that neither face is visible.

Title: Process for the fractionation of fats
IPC: C11B7/00
Filed: 1964-06-11
Abstract: Fats are fractionated by crystallization by adding melted fat to an aliphatic hydrocarbon solvent having from 5 to 7 carbon atoms which is at or below such a temperature that the higher melting components of the fat begin to crystallize on mixing, stirring and filtering off the crystallized fat.  The slurry may be cooled while stirring.

Title: Improvements in decolourizing or bleaching montan wax
IPC: C10G73/00
Filed: 1927-09-15
Abstract: 302,626. Johnson, J. Y., (1. G. Farbenindustrie Akt.-Ges). Sept. 15, 1927. Purifying mineral and other waxes.-Montan wax is bleached in absence of acetic or other organic solvent, by suspending in an aqueous solution of sulphuric acid or of a chromium salt or of both, adding a solution of chromic acid, and heating to above 100‹ C. Preferably the temperature is raised during the reaction by allowing water to evaporate and so concentrating the solution, or the operation is conducted under pressure. The chromic acid is preferably used in batches, the spent solution being withdrawn before addition of the next batch. In an example, 100 kilograms of crude montan wax are emulsified at about 100‹ C. in 400 litres of spent chromic acid solution, and stirred and heated while 1200 litres of electrolytically regenerated chromic acid solution are run in. The bleached wax, preferably after drawing off of the chromium solution, is freed from green salts by standing, when the colourless wax forms an upper layer. It may finally be treated with boiling dilute sulphuric acid. It is stated in the Specification that paraffin wax, beeswax, and the like which have been bleached by chromic acid may be similarly freed from green pigments instead of by repeated extraction with boiling dilute sulphuric or oxalic acid or like substance.

Title: Method of production of a separating layer paper for the ceramic industry
IPC: D21H17/68
Filed: 1962-07-02
Abstract: Paper which contains a relatively high proportion, e.g. 55%, of pure quantz powder and which may be used as a separating or supporting paper in the firing of ceramic ware is prepared by adding quartz sand to a slurry of cellulosic fibres in a paper machine beater, in relative amounts of 25-35% cellulose and 65 to 75% quantz sand.  The blade distance of the beater is adjusted to a fine setting and the pulp beaten for at least one hour and then deposited directly on a conventional strainer screen.  Drying is effected almost exclusively by pressure and heat with some natural drainage occurring, suction and agitation of the screen being avoided.  Chemically pure sand of analysis 99.8% SiO2 is preferably employed and a minor amount (0.5% to 1% of the dry weight of the pulp) of resin glue may be added.  To ensure maximum retention of the sand in the paper intermediate steps between the beater and strainer screen, such as, e.g. centrifugal separation of larger particles and knot separation, are omitted.
