IPC: G21K4/00
Filed: 1953-12-01
Abstract: 785,114. Luminescent materials. THORN ELECTRICAL INDUSTRIES, Ltd. Nov. 5, 1954 [Dec. 1, 1953], No. 33407/53. Class 39(1). Luminescent material comprises calcium in the substantially pyrophosphate form (ratio of metal oxide, excluding the tin activator, to P 2 O 5 - lying between the limits 2: 0À9 and 2: 1À4 inclusive) of the a and/or type (as defined by X-ray diffraction lines), activated by tin of lower valency than stannic tin, with or without manganese, the manganese when present constituting up to about one half of the metal content (excluding the tin activator) of the luminescent material. The proportion of tin is not less than 0À05 per cent and not more than 10 per cent by weight of the luminescent material. Up to but not including 2 molecular per cent of the calcium can be replaced by one or more strontium, barium, zinc or magnesium. The material can be prepared by heating at a temperature of above 700‹C. and below the melting point of the material a mixture comprising a matrix of calcium pyrophosphate, or of calcium pyrophosphate and manganese pyrophosphate, or compounds yielding such a matrix on heating, having the desired ratio of metal oxide to P 2 O 5 , and a tin compound, the heating conditions being such that the tin is in a lower valency state than stannic tin and the calcium pyrophosphate of the matrix is in the alpha and/or beta form. The manganese can be added to the mixture in the form of the carbonate or phosphate such as the hydrogen phosphate. The tin can be added to the mixture in the form of the oxide, chloride or phosphate and the heating carried out under non-oxidising conditions, for example in a plugged tube or covered crucible or in steam and/or nitrogen mixtures of hydrogen therewith. If the tin is added in the stannic state the heating is carried out in a reducing atmosphere. Examples are described in which calcium hydrogen phosphate or calcium carbonate are heated with diammonium hydrogen phosphate and tin with or without manganese compounds to temperatures of 1120‹C. or 1220‹C. or to 850‹C. with reheating to 1220<SP>0</SP>C. The calcium pyrophosphate matrix can be prepared first and the tin compound incorporated therein by heating under non-oxidizing or weakly reducing conditions.

Patent GB-1037267-A (GB)
Title: Making papers from man-made fibres
IPC: D06N7/00
Filed: 1963-08-23
Abstract: Paper is made from man-made fibres, by processing the fibres into a batt on a conventional papermaking machine in association with a lubricant and a bonding material.  The bonding material comprises at least one thermoplastic having a melting point higher than that of the lubricant and is not miscible with the lubricant when liquefied. The fibres are bonded together by heating the batt above the melting point of the thermoplastic, so that lubricant melts first and coats the fibres and the thermoplastic melts and moves along the lubricant to the point where the fibres intersect, and then cooling the batt. The bonding agent may be added in the form of staple fibres, and the lubricant may be applied to them.  Suitable man-made fibres are: polyamide fibres, polyester fibres, polyacrylic copolymer fibres, man-made cellulosic fibres, and glass fibres.  They may be mixed with natural fibres.  The thermoplastic bonding agent may be the polyamide obtained by condensing dimerized and trimerized unsaturated sebacic acids with polyamines.  Suitable lubricants are: alkylglycol phthalates, natural or synthetic resins, balsam resin ammonium soap, and polyesters derived from adipic, sebacic or phthalic acid.  In another embodiment, the lubricant is first applied to fibres of nylon, and fibres of the above polyamide bonding agent are then added.

Title: Improvements in or relating to lubricating compositions
Inventor: MACDONALD CHARLES STEWART
Filed: 1954-11-19
Abstract: A lubricating composition, suitable for use in metal-working operations, comprises a halogenated kerosine and 0.005-5 per cent by weight, based on the total composition, of an ester of a polyhydric alcohol, or a polyoxyalkylene derivative thereof, soluble in the halogenated kerosine.  Polyhydric alcohols mentioned are mannitol, dulcitol, sorbitol, sorbitan, sorbitide, glycerol, glycol, polyglycols, pentaerythritol and d-arabitol. The esters may be derived from fatty acids such as oleic, ricinoleic, lauric, palmitic or stearic acid.  Specific esters mentioned are sorbitan mono-oleate or mono-laurate, or the corresponding multi-esters such as the tri-oleate; glycerine mono- or di-oleate, mono- or tri-ethyleneglycol mono- or di-oleate, pentaerythritol mono-, di- or tri-oleate or any of the corresponding lauric, erucic, stearic, ricinoleic or palmitic esters.  The hexitol esters may be converted to their polyoxyalkylene derivatives by reaction with ethylene or propylene oxide.  The lubricating composition may contain additional esters (e.g. fatty acid esters of monohydric alcohols, such as isopropyl oleate, esters of dicarboxylic acids such as adipic or azelaic acid, particularly with long-chain oxo alcohols and complex esters) and soluble metal naphthenates (e.g. iron, aluminium or zinc naphthenate).  In an example, a lubricating composition consists of chlorinated kerosine and polyoxyethylene sorbitan mono-oleate.  According to the Provisional Specification, other halogenated hydrocarbons may be employed instead of halogenated kerosine, for example chlorinated gas oils and liquid chlorinated waxes, while the lubricating composition may also contain animal or vegetable oils (e.g. lard oil, sperm oil, tallow, rapeseed oil, coconut oil and castor oil) or fatty acids (e.g. oleic or pelargonic acid).  Specifications 769,427, 778,812 and 778,920 are referred to.
