Abstract: Polyethylene glycol monoesters of halogenated aliphatic acids are prepared by heating the acid with varying proportions of ethylene oxide, preferably in the presence of a boron trifluoride catalyst. Reference is made to the mono-esters from brom- and iodo-acetic acid having an average of 50 ethylene oxide units.  It is stated that the bis-esters may be made by reacting the acid halide of a halogenated carboxylic acid with a polyethylene glycol having, for example, up to 200 ethylene oxide units. Alternatively they can be made by reacting the acid itself with the glycol in the presence of an esterification catalyst such as sulphuric acid or p-toluene sulphonic acid. Specification 235,211 [Class 2 (iii)], is referred to.ALSO:Esters of the formula <FORM:0751580/IV(a)/1> wherein R is a halogenated alkyl group and n is a positive integer are made by heating the halogenated aliphatic acid with varying proportions of ethylene oxide, preferably in the presence of a boron trifluoride catalyst.

Abstract: 1,097,016. Baling presses. FLETCHER & STEWART Ltd. June 21, 1965 [June 30,1964]. No. 27051/64. Heading B5F. A baling press comprises a compression box 1 which can be moved, e.g. by pneumatic or hydraulic rams 22a, to a position clear of the material while the material is retained in its compressed state, so that strapping of the material is facilitated. As shown, the press comprises two boxes 1, 2 rotatable about a column 5 so that one box can be filled while material in the other box is being compressed. Rotation is effected by two double-acting rams 6 connected by a chain 7 passing round a sprocket 8. The material is pre-compacted by a trampler 10 and compressed by a main press ram 14. Spring- biased pivoted fingers (11), Fig. 2 (not shown), for holding the trampled material down, are received in grooves or slots (13a) in the trampler. Modifications.-The press may alternatively have one, three or four press boxes. The press may be upstroking instead of downstroking. Instead of the rams 22a, a screw, toggle or lever gear may be used for moving the box 1 clear of the compressed material.

Title: Improvements in or relating to rubber springs
IPC: F16F1/36
Filed: 1952-10-29
Abstract: In a rubber spring of the type in which two relatively movable, spaced, rigid members are bonded to an intermediate body of vulcanized natural rubber composition and in which the load is yieldingly carried by shear stresses imposed upon the rubber body, the rubber composition contains not more than 5 per cent by weight of rubber-insoluble particulate matter.  Particulate matter is defined as matter which does not dissolve in rubber during vulcanization and includes carbon black, silica, silicates, some carbonates, whiting, barytes, talc, infusorial earth, slate, flour and cellulosic fibres. In Examples, springs are made from a mix consisting essentially of natural rubber, sulphur, stearic acid, zinc oxide, an anti-oxidant such as phenyl-beta naphthylamine or a condensation product of 4-amino diphenyl with acetone; and an accelerator chosen from N-cyclohexyl-2-benzothiazole sulphenamide, mercaptobenzothiazole, cyclohexyl diethyl thiocarbamyl sulphenamide, or benzothiazyl disulphide with dibutyl ammonium oleate, to this mix up to 10 per cent of carbon black or litharge may be added.  Other accelerators which may be used as thiazole sulphenamides, thiazoline sulphenamides, thiocarbamyl sulphenamides, mercapto thiazoles, mercapto thiazolines, thiazolyl disulphides, dithiocarbamates, thiuram sulphides, xanthogen sulphides, metallic salts of mercaptothiazoles or mercaptothiazolines or dithiocarbamic acids, lead oxides and salts, and activators such as guanidine derivatives, and amine salts, and salts such as sodium acetate.  The sulphur may be replaced, wholly or in part, by selenium, tellurium, phenol polysulphides, xanthogen polysulphides, thiuram polysulphides or dialkyl polysulphides, or by nitroso compounds, oximes, nitro compounds or azo compounds.

Title: Improvements in or relating to production of refractory metals
IPC: C22B34/00
Filed: 1954-09-23
Abstract: A refractory metal, e.g. Ti, Zr, U, Th, V, is produced by reacting its oxide with one or more alkali metals and one or more halides of calcium at elevated temperature.  The reaction is performed in an inert atmosphere at 800 DEG -900 DEG C. for at least 30 minutes with agitation of the reactants.  The reactions may be performed in several stages, the product from each stage being treated with further alkali metal and calcium halide.  The reaction may also be performed as a continuous process, any unreacted alkali metal being distilled off from the refractory metal and returned to the reaction chamber.  The alkali metal may be formed by electrolysis of a molten salt bath (see Group XXXVI) and the refractory metal oxide added at the cathode to produce the required metal.
