Patent GB-482818-A (GB)
Title: Improved process for enhancing the resistance of textile fabrics to creasing
IPC: D06M15/423
Filed: 1936-08-04
Abstract: The resistance of textiles to creasing is enhanced by impregnation with a water-soluble formaldehyde condensation product such as dimethylolurea, and if desired a softening-agent, and then conducting the drying of the impregnated material so that there is present an ammonium salt of a strong acid which at a temperature below 100 DEG C. sets free acid.  Suitable salts are ammonium chloride, sulphate and formate, and acid ammonium phosphate.  After impregnation, the material is pressed or centrifuged to a desired extent, and if desired allowed to remain in a closed chamber, for example, by being enveloped in a rubber cloth; the material is afterwards dried, and if desired soaped. In examples, ammonium chloride with in one case an addition of monosodium phosphate is used as the source of acid, and a mixture of sulphonated or non-sulphonated mono-cetyl ester of phthalic acid employed as the softening-agent.  Reference has been directed by the Comptroller to Specification 449,243.

Patent GB-798675-A (GB)
Title: Process for the manufacture of stabilising pastes for resinous compositions
IPC: C08K5/00
Filed: 1956-07-12
Abstract: A flushed paste having heat stabilizing properties for resinous compositions is prepared by agitating an aqueous filter cake of a basic lead salt of a saturated or unsaturated monobasic aliphatic carboxylic acid having 6-22 carbon atoms per molecule with a water-immiscible organic vehicle and separating the water portion. The organic vehicle is preferably a plasticizer, e.g. dicapryl phthalate, di-iso-octyl phthalate, di-2-ethyl hexyl phthalate, hexyl isodecyl phthalate, polyalcohol esters of adipic acid, polyglycols, triphenyl phosphate, and bis - (2 - ethyl - hexyl) - 2 - ethyl - hexyl phosphonate; other suitable organic vehicles are mineral oil and petroleum jelly.  Basic lead salts of the following acids may be used: caproic, caprylic, 2-ethyl-hexoic, lauric, capric, palmitic, undecylic, stearic, behenic, and oleic acids.  When using salts of higher molecular weight acids, the transfer to the organic phase may be assisted by raising the temperature and/or by adding a small amount of a lower aliphatic alcohol.  Agitation may take place in a mixer having a vibratory or kneading action.  The flushed paste may be heated under vacuum to remove more of the water.  In examples, dibasic lead salts of hydrogenated tallow fatty acids, coconut oil fatty acids, behenic acid, and oleic acid are dispersed in specified plasticizers.  A flushed paste of dibasic lead stearate in mineral oil is also useful as a lubricating composition.  Specification 798,444 is referred to.
