Title: Improvements relating to the production of mono alkyl ethers of glycol and its homologues
Filed: 1930-10-17
Abstract: Mono-alkyl ethers of glycol and its homologues are prepared by the action of alkylene oxides on alcohols with the addition of dimethyl or diethyl sulphate.  For example, 30 parts by volume of ethylene oxide with 300 parts of ethyl alcohol are heated under pressure in an autoclave with the addition of say 1 part of diethyl or dimethyl sulphate.  The temperature may be maintained at 100 DEG  C., so that a pressure of 50-60 lbs. per square inch is developed.  When the pressure falls to 20-25 lbs. per square inch, the contents of the autoclave are cooled down.  The mono-ethyl ether of ethylene glycol is separated by fractionation.

Title: Improvements in or relating to the production of grey cast iron
IPC: C22C37/00
Filed: 1937-02-10
Abstract: An all-pearlitic (which may be partly or wholly sorbitic) structure with possible traces of cementite, but no free ferrite whatsoever, is produced in grey iron castings made in cold moulds of sand or other refractory material or in hot or cold metal moulds and containing materials which inhibit and promote the formation of ferrite, by altering (a) the quantity of ferrite-promoting material (which must always be so high as normally to produce a ferritic casting), (b) the quantity of ferrite-inhibiting material, and (c) the rate of cooling of the casting as determined by its section and, in the case of metal moulds, the mould-temperature, the method being carried out without superheating the mixture to such a high temperature before pouring the casting that its structure would be affected thereby.  The ferrite-promoting material may be one or more of silicon, nickel, or copper in amount equivalent to 2-7 per cent of silicon, it being reckoned that 0,4 per cent of silicon is equivalent to 1 per cent of nickel and 0,35 per cent of silicon is equivalent to 1 per cent of copper, no more than 3,5 per cent of nickel and 4 per cent of copper being, however, present.  The ferrite-inhibiting material may be one or more of chromium, manganese, or molybdenum in amount up to 6 per cent, up to 3,5 per cent, and up to 1,5 per cent respectively, it being reckoned that 0,3 per cent of molybdenum is approximately equal to 0,2 per cent of chromium and 0,25 per cent of manganese (after the first 1,75 per cent of manganese which is stated to be without effect) being equal to 0,15 per cent of chromium. The inhibiting-material may be added to the cast in the pouring-ladle, the cast preferably containing a quantity of scrap from a previous operation.  British Specifications 147,933, [Class 82 (i)], 495,475, and 495,820, and U.S.A. Specification 1,910,034 are referred to. Reference has been directed by the Comptroller to Specification 245,196, [Class 82 (i)].

[Also in Division F2]   A hollow tube having an end attachment comprising an expandable sleeve, which is a slidable, non-rotatable fit in the tube, having a bore of greater and lesser widths in mutually perpendicular directions, and a spigot, having a maximum cross-sectional dimension intermediate the said widths, whereby the spigot may be slidable inserted within the sleeve when its maximum dimension lies within the greater bore width and the tube, sleeve and spigot being interlocked by expansion of the sleeve on relative rotation of the spigot within the sleeve. In the construction shown, square tubes 10, 11, 12, 13 forming a frame are firmly connected by end attachments 14, 15, 16, 17, each comprising mutually perpendicular oval-shaped spigots 22, 23 extending from cubical members 21 and squareshaped nylon sleeves 24 having a corresponding oval-shaped open-sided bores 30. Each connection is made by clipping the sleeves over the spigot with the respective major axes of both oval cross-sections of bore and spigot in alignment and slidably inserting the sleeve in the tube. The tube, and hence the sleeve, is then twisted through 90 degrees thereby disaligning the major axes, causing expansion of the sleeve member by the spigot and interlocking of the tube, sleeve and spigot. The spigot carries a stop 28 so that on disassembly of the joint by further relative twisting of the spigot within the sleeve, the sleeve may be retracted with the spigot. A frame thus formed may mount triangular brackets 19 having projecting ears engaging pairs of tube slots 18. In a modification Figs. 7 and 8 (not shown), a closed frame is formed by springing the frame members into outwardly-facing channel members of a dished panel.
