Patent GB-739484-A (GB)
Title: Emulsified oil composition
Inventor: PUTMEN JOHN HAROLD
IPC: C09K23/00
Filed: 1952-04-01
Abstract: An emulsion, which imparts a high degree of corrosion resistance to acid-pickled steel strip dipped therein, comprises a major proportion of water and a minor proportion of a soluble oil composition comprising a major proportion of lubricating oil, a minor proportion of one or more emulsifying agents and 0.2-5 per cent by weight, based on the total soluble oil composition of a metal alkyl dithiocarbamate.  The lubricating oil is preferably mineral oil while the dithiocarbamate may be zinc dibutyl dithiocarbamate.  Suitable ionic emulsifying agents are oil-soluble metal petroleum sulphonates or naphthenates, but it is preferred to use at least two non-ionic emulsifying agents, one of which is more oil-soluble than water-soluble and another is more water-soluble than oil-soluble. The polyoxyethylene derivatives of long chain fatty acid esters of hexitol anhydrides such as sorbitan, or the polyoxyethylene derivatives of alkylated phenols, particularly sorbitan monooleate, monostearate, monolaurate or monopalmitate, may be employed as the non-ionic emulsifying agent which is more water-soluble than oil-soluble. Long-chain fatty acid esters of nona-ethylene glycol or of lower polyethylene glycols, particularly the monooleates of nona- or tri-ethylene glycol, may be employed as the non-ionic emulsifying agent which is more oil-soluble than water-soluble.  The soluble oil composition may also contain a minor proportion of an alkylolamine salt of an acid of phosphorus, particularly triethanolamine phosphate.  In the examples, aqueous emulsions are prepared from soluble oil compositions consisting of mineral lubricating oil, zinc dibutyl dithiocarbomate and either (i) sodium mahogany sulphonates, naphthenic acids, caustic soda, water, diethylene glycol, sodium benzoate and silicone antifoaming agent, or (ii) oleic acid, triethanolamine, triethylene glycol monooleate, the polyoxyethylene derivative of alkylated phenols known as "Lissapol NX" (the word "Lissapol" is a Registered Trade Mark) and water, or a blend of (i) and (ii).  Tests are described in which the compositions of the examples are compared with similar compositions from which the zinc dibutyl dithiocarbamate has been omitted.  According to the Provisional Specification, corrosion inhibitors other than metal alkyl dithiocarbamates may be employed, for example guanidine, mercaptobenzthiazole, urea, alkylated ureas, thiourea and alkylated thioureas such as 2-ethyl thiourea and ethylene thiourea.

Patent GB-677840-A (GB)
Title: Process for impregnating and sizing
IPC: D06N3/00
Filed: 1949-03-31
Abstract: Textile or paper articles are impregnated and sized by applying a quantity of latex dispersion containing from about 60 per cent to 75 per cent of dry rubber to the surface of the article or to a plate or plates, subjecting the article to pressure between said plates to cause the latex dispersion to penetrate into its pores, and then suddenly releasing the pressure, thus bringing about coagulation of the latex.  Dyes, fillers, plastifiers, vulcanizing or preserving agents may be added to the latex.  The pressure may be applied by a press, the co-operating plates of which may have complementary raised or sunk patterns.  The latex may be applied directly to both surfaces of the material by a spray-gun, roller or scraper, or by dipping, or it may be coated on a flat surface, as a pattern or otherwise, and applied to one or both surfaces of the material under pressure.  The impregnated material may be heated to vulcanize the rubber, if necessary, and dried; the material may be dried before impregnation, and subsequent drying omitted.

In an hydraulic tappet between an engine cam 2 and a valve stem 12, an oil pressure chamber 5 between an outer cylinder 1 and a mating piston 4 is vented by an oil exhaust passage 15 in the cylinder 1 which is throttled intermittently by the cam 2 to give a pulsating throughput of engine lubricating oil to prevent air build-up in the pressure chamber 5. Oil from a passage 10 enters, via ports 9, 8 in the cylinder 1 and piston 4, a chamber 7 in the piston 4 from whence it enters the pressure chamber 5 through a ball check-valve 6. Oil from the chamber 5 is further throttled around a piston 16 in the cylinder 1 before passing through the exhaust passage 15. A spring 11 biases the piston 4 against a retaining ring 13 in the cylinder 1.

Abstract: 967,240. Capacitors. TELEPHONE MANUFACTURING CO. Ltd. June 16, 1961 [March 16, 1960], No. 9262/60. Heading H1M. In a method of sealing an electrical component within a casing a non-resilient dished sealing member is disposed within the end of the casing to be free fitting and then deformed in such a way as to increase its dimensions in a direction as to seal the member within the opening. The invention is particularly applicable to sealing rolled capacitor elements 10 within a cylindrical insulating casing 13, which is preferably made from polypropylene or a styrene butadiene acrylonitrile blend. The casing has shoulders 14 and 15 in its inner bore against which dished metal discs 16 and 17, made preferably from tin-plated steel, are fitted and then pressed in. This causes the discs to be tightly sealed against the casing, and the leads 11 and 12 may then be soldered to them. Several types of casing shapes are described (Figs. 2, 3 and 4, not shown) and a method of sealing the metal discs into a tube of uniform bore, using a mandrel to support the discs is discussed (Figs. 5 and 6, not shown). Other materials suitable for use as the casing and the sealing discs are mentioned.
