Abstract: 568,808. Impregnating articles under vacuum. GENERAL ENGINEERING CO. (RADCLIFFE), Ltd., TAYLOR, S., TILLS, J. W., LOVATT, J. B., and POTTS, F. C. Aug. 10, 1943, Nos. 12894/43, 13497/43, and 14709/44 (divided out of 568,816). [Class 140] [Also in Group XXVI] In apparatus for impregnating under vacuum articles such as condensers or transformers with oil, paraffin wax, or a mixture of rosin and oil, a pump disposed in one evacuable vessel is adapted to transmit impregnant to a second evacuable vessel, either one of said vessels being a conditioning and/or storage vessel and the other being an impregnator. An impregnating vessel 11 is mounted in vacuum-tight relation to an impregnaut storage and treatment vessel 12, the vessels being separately evacuable through connections 27, 28, and vessel 12 containing a pump 13 adapted to transmit liquid impregnant to a spray ring 25 in vessel 11, through pipes 16-20, and then either direct through valve 24, or through a filter 21 and valves 22, 23. A heat-exchange coil 47 in the vessel 12 may be heated or cooled by passage therethrough of steam or cold water, and the vessels have heating jackets 48, 49. In operation, both vessels are heated and the storage vessel 12 containing the impregnating liquid is evacuated while the lid 29 of vessel 11, which is empty, is removed for introduction of the articles to be treated. After replacing the lid 29 and evacuating vessel 1, the impregnating liquid is pumped by means of pump 13 into vessel 11 and rises to a level determined by an adjustable overflow pipe 38, 39. Liquid returning to the storage tank through the overflow pipe and valve 44 flows over heat-exchange coil 47. At the end of the treatment, drain valve 37 is opened, the pump is stopped, and the liquid returns by gravity to the storage vessel 12. Valves 37 and 44 are controlled, and pump 13 is driven, by means located outside the vessel 12. In a modified apparatus having separate storage and impregnating vessels, the storage and conditioning vessel contains two pumps which are used for transferring the liquid to the impregnating vessel, and also, as described in Specification 568,816, to enable the treatment liquid to be sprayed into the storage vessel for de-aeration, passed through the heat-exchanger for heating or cooling, filtered, drawn from a supply vessel, drawn from or supplied to the impregnating vessel, and put under pressure in that vessel. Specification 568,105, [Group XXVI], is referred to in the first two Provisional Specifications.

Filed: 1955-05-05
Abstract: Epoxy resins are hardened by addition of a homogeneous mixture of an aliphatic primary polyamine and an aliphatic tertiary hydroxylated amine in a weight ratio between 5 : 95 and 40 : 60. Primary polyamines are ethylene triamine, triethylene tetramine, diethylene triamine and hydroxylated tertiary amines are diethylaminoethanol and 1-, 2- or 3-diethylaminopropanol.  5-20 parts of the mixture are used to 100 parts epoxide resin.  Curing may be effected at 20 DEG  C. without heating but temperatures up to 250 DEG  C. may be used. Preparation of two resins designated A and B are described.  A is prepared by heating a solution of 11.7 parts water, 1.22 parts NaOH and 13.34 parts diphenylol propane to 70 DEG  C. and after cooling to 45 DEG  C. adding 14.06 parts epichlorhydrin. A further 5.62 parts NaOH in 11.7 parts water is added gradually over a period of 2 hours. NaCl formed was removed by washing and the product dried at 80 DEG C. under 25 mm. vacuum to give a viscous liquid resin.  (B) 376 parts phenol were reacted with 63 parts formaldehyde in presence of a boron trifluoride-ethyl etherate dissolved in dioxan.  263 parts of the phenol-aldehyde condensate obtained were reacted with 365 parts epichlorhydrin in presence of 210 parts 50% NaOH.  A permanently fusible freely-flowing resin was obtained.  In examples, curing agent C consisting of a mixture of 10 parts diethylene tetramine and 90 parts diethylaminoethanol was mixed with Resin B at 27 DEG  C.  The mix was usable up to 8 hours and there was no heat release but it gelled within 24 hours.

Abstract: 500,158. Refining cellulosic materials. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCH RESEARCH CENTRALE, and BERTRAM, S. H. May 2, 1938, No. 13092. [Class 2 (ii)] Binding matter is removed from raw vegetable fibres by treating them at atmospheric pressure with a substantially neutral aqueous solution of a salt containing an ion, other than a phosphate ion, the calcium salt of which has a lower solubility product than calcium pectate, and a cation the pectate of which is soluble in water. The salt solution is in general used in a concentration of not less than 1 per cent. During the treatment, calcium pectate is separated from the fibres and converted into an insoluble non-adhesive calcium salt and a soluble pectine compound. The salt employed for the treatment may be sodium fluoride, or ammonium oxalate. Dilute solutions are used in order to avoid salting-out of sodium pectate. Treatment may be effected in the cold or with a heated solution. In examples, raw flax stalks are treated at 95-100‹ C. with a 1 per cent sodium fluoride solution, or with a z per cent ammonium oxalate solution, or are treated in the cold with a 3 per cent sodium fluoride solution. The treatment may be followed, after washing, by a treatment with hydrochloric acid for the removal of calcium salts. Specification 296,333, [Class 120 (i)], is referred to.
