Title: Improvements in or relating to the production of hardenable epoxy resin compositions
Inventor: HOUSTON DAVID ARTHUR
IPC: C08G59/18
Filed: 1961-01-06
Abstract: A modified hardenable epoxy resin is made by blending a siliconized epoxy ester made by reacting an unsaturated fatty acid ester with silicon tetrachloride (see Specification 889,800), with an epoxy resin derived from epichlorohydrin and a polyphenol, by stirring the components together at such a temperature that blending takes place readily.  In a modification of the process, the siliconized epoxy ester before blending with the epoxy resin is reacted with an excess of a dry alcohol and the unreacted alcohol removed by distillation. The example describes the reaction of epoxidized soya bean oil with silicon tetrachloride, the product being blended with an epoxy resin derived from epichlorohydrin and bis-phenol-A and the mixture hardened by reaction with phthalic or hexahydrophthalic anhydride optionally in the presence of benzyldimethylamine or a -methylbenzyldimethylamine.

Title: An improved fluid-flow control valve
IPC: F15B13/04
Filed: 1954-01-11
Abstract: 805,613. Valves. AUTOLIFTS & ENGINEERING CO. Ltd., and KIDD, W. B. Feb. 7, 1955 [Jan. 11, 1954], No. 697/54. Class 135. A non-return valve 23, situated in a line leading from a pump to a jack, seats on a member comprising two members 13, 17, slidable one over the other and with a compression spring 27 located between them. The valve is urged towards the seat by a light spring 25. The net area of member 17 which is acted upon by pump pressure urging the member towards the other member 13 is greater than the area of member 13 on the downstream side of the valve. When the pressure in the jack becomes equal to that on the upstream side of the valve the valve will close, and the pressure in the jack will then act on the member 13 to force it towards the member 17 until ports 29 in the member 13 become exposed and the fluid from the pump can then flow directly to the sump passage 9. The travel of member 17 is limited by a shoulder 22 on a plug inserted into the inlet end of the valve body. Specification 805,612 is referred to.
Patent GB-773237-A (GB)
Title: Process for softening hard paraffin wax by cracking
IPC: C10G73/38
Filed: 1955-01-10
Abstract: Hard paraffin wax, particularly that having a setting point of about 90 DEG -100 DEG C., obtained synthetically from carbon monoxide and hydrogen, is softened by a process wherein the wax is submitted to thermal cracking at 370 DEG -450 DEG C. for 3 to 20 minutes, the cracked products are distilled at about atmospheric pressure to remove hydrocarbons boiling up to 340 DEG C. and the residue thereby obtained is then distilled in a second distillation zone at an absolute pressure in the range of 1 to 3 mm. Hg to give a distillate (B.R. 340 DEG -550 DEG  at atm. pressure) from which wax having a melting point in the range 40 DEG -80 DEG  is separated.  The waxes, obtained as products may be used in the production of polishing waxes, shoe polishes, and candles.  In order to separate wax from the vacuum distillate it may be submitted to catalytic hydrogenation under pressure at about 250 DEG C., then dissolved in a solvent, and the solution cooled.  The residue from the vacuum distillation may be mixed with fresh hard wax to be treated.  In an example, a mixture consisting of 35 parts (by weight) of synthetic hard wax and 65 parts of vacuum-distillation residue boiling above 550 DEG C. was passed through a tube heated to 425 DEG C., the residence time in the tube being 8 minutes.  The effluent was distilled at normal pressure to remove components boiling up to 340 DEG C.; and the bottoms were then flashed in a column operated at an absolute pressure of 1mm. Hg.  The head of the vacuum-column was maintained at 275 DEG C., and a fraction boiling at 340 DEG -550 DEG C. at normal pressure was taken overhead.  This fraction was separated by distillation at 3 mm. into a distillate boiling in the range 340 DEG -460 DEG C. and a residue. These two fractions, after addition of a catalyst, comprising metallic nickel and magnesium oxide supported on kieselguhr, were separately stirred for 1 hour in an autoclave at 250 DEG C. under a hydrogen partial pressure of 50 atm. and subsequently separated from the catalyst by filtration.  The hydrogenated light fraction was mixed at 60 DEG C. with a solvent comprising isopropanol and benzene, cooled to 20 DEG C. and filtered at this temperature.  The filtration-residue, after washing and freeing from solvent, comprised slab wax having a pour point of 58 DEG C.  A wax having a pour point of 44 DEG C. was separated from the filtrate by cooling it to 5 DEG C.  The hydrogenated heavy fraction was treated with solvent in a similar manner, and yielded a wax having a pour point of 73.5 DEG C. and an extraction oil having a pour point of 27 DEG C.  Waxes produced in accordance with the invention and having melting points of about 70 DEG C. are suitable for the manufacture of candles. Heat-resistant candles particularly suitable for use in the tropics can be produced from blending wax having a melting point of 68 DEG -75 DEG C. with an equal amount of a wax having a melting point of 56 DEG -62C DEG .
