Patent GB-606319-A (GB)
Title: A process for the manufacture of a product suitable for use as a lubricant or as an addition to a lubricant
IPC: H01L23/48
Filed: 1946-02-11
Abstract: Products suitable for use as lubricants, or as lubricant additives, are prepared by heating a solution or dispersion of a salt of a polyvalent metal and an aromatic monocarboxylic mono-or multi-nuclear acid (either substituted in the nucleus or not) in a non-polar or weakly polar liquid, e.g. a mineral lubricating oil, so that the salt decomposes.  The heating is then continued until the decomposition products precipitated during the first stage have entirely dissolved, or nearly so, after which the liquid medium may be removed entirely or in part, e.g. by vacuum distillation.  Salts of salicylic acids substituted by alkyl groups may be employed.  The salts may be of metals of the second and third groups of the periodic system, e.g. zinc or calcium, and those of the sixth group and of the iron group are also suitable. In an example, one part by weight of a zinc salt of di-isopropyl salicylic acid is heated to about 230 DEG  C. with two parts by weight of mineral lubricating oil.  At about this temperature the formation of an insoluble decomposition product sets in, carbon dioxide being evolved.  The temperature is increased in order to redissolve the precipitate formed, solution being complete at 300 DEG  C.  The oil can be removed by high vacuum distillation, leaving a solid substance with a zinc content of about 30 per cent which, when heated to about 150 DEG  C. is miscible with mineral oil in practically any proportion and remains dissolved in the oil at room temperature.  Kerosine or an ether with a high molecular weight, such as di-n-dodecyl ether may be used in place of mineral lubricating oil, but it is then advisable to remove all or most of the liquid medium before using the residue as an additive for lubricants.  If the salt used as a starting material is difficult to disperse in the liquid medium, a dispersant such as high molecular weight alcohols may be used.  A small proportion of the product, e.g. 0.1 per cent by weight (calculated in the basis of metal) present in internal-combustion engine lubricants is said to reduce corrosion, wear and ring sticking.

Title: Improvements in the manufacture of vitreous stems for tubular electric lamps
IPC: H01J9/32
Filed: 1946-02-13
Abstract: 607,843. Metal-to-glass seals. COLE, Ltd., E. K., and HAEGELE, F. G. A. Feb. 13, 1946, No. 4433. [Class 36] In making short vitreous stems of the squat frustro-conical type for use in tubular electric lamps, the formation of the stem and sealing of the leading-in wires between the stem tube and exhausting tube is effected by the application of a mould about the softened neck of the stem tube and the application of a gas under pressure to the inside of the exhausting tube and/or between the tubes to form a seal of the shape of the mould. The exhausting tube, and the space between that tube and the stem tube, are preferably subjected to slight suction immediately before the admission of the pressure gas. A stem tube 1 with an integral flare 3 is placed on a support 2 shaped to the flare, and a glass exhausting-tube 6, which may be closed at its upper end, is placed within a central support provided with an axial passage 9 and a lateral tube 8, the former being in communication with the interior of the tube 6 while the latter communicates with the inside of the tube 1 via the space 12 between the tube 6 and the inside wall of the support therefor. A pair of lead-in wires 4 is located between the stem tube 1 and the support for the exhausting-tube. The tube 1 is heated by flames directed thereon and softens and collapses on to the lead-in wires and exhausting- tube, whereupon a slight suction is applied to the tubes 8, 9, the suction at 8 being greater than that at 9 so that the glass is drawn downwardly towards the flare 3 and covers and seals the wires without distorting the glass below the seal. A two-part mould 13, Fig. 2, is next brought to enclose the still plastic glass, and air or gas under pressure is blown through the tubes 8, 9, thereby opening the upper end of the exhaust tube and blowing the glass evenly to the shape of the mould. The mould may be provided with recesses 14 disposed adjacent to the wires so that supporting beads or nodules of glass are formed at the upper junctions between the wire and glass. The operations may be performed automatically in a turret machine.

Title: Production of artificial silk having a wool-like character
IPC: D02G1/02
Filed: 1941-04-08
Abstract: 548,079. Treating artificial silk; waterproofing ; dyeing processes. HEBERLEIN & CO. AKT.-GES. April 8, 1941, No. 4672. Convention date, April 9, 1940. [Classes 2 (ii) and 15 (ii)] [Also in Group VIII] Artificial silk, having a wool-like character,. is obtained by imparting to twisted or untwisted artificial silk threads a high degree of twist to an extent at least four times the normal value, winding the fibres in this state on a bobbin, moistening them at a high temperature and drying while still on the bobbin, twisting them in the opposite direction beyond the zero point, and subjecting them before, during or after the twisting or reverse-twisting operation to a treatment with formaldehyde or a substance yielding formaldehyde in presence of an acidic catalyst at a temperature of 90-160‹C. If desired, the threads may also be steamed while in an untensioned condition after the twisting in the reverse direction beyond the zero point. The treated threads retain their wool-like character after washing, working-up, and after being subjected to wear. If dyes, resistant to formaldehyde, are used, e.g. naphthol or vat dyes, the formaldehyde treatment imparts improved fastness to washing. The threads may also be rendered water-resistant by combining the formaldehyde treatment with a water-proofing treatment, e.g. treatment with stearyl or montanyl isocyanate. In an example, viscose yarn is highly twisted, wound on a bobbin, and steamed under pressure. It is dried and then twisted in reverse beyond the zero point. It is impregnated in the hank with a solution of formaldehyde and aluminium thiocyanate. It is pressed, preliminarily dried, and then heated at 120‹C. After soaping and washing, it is again steamed. Cuprammonium silk yarn may be treated similarly. Ammonium chloride may be used as catalyst for the formaldehyde treatment. Specifications 397,046 and 417,174 are referred to.
