Title: Method of manufacturing a stable organic ferro-compound
IPC: C07F15/02
Filed: 1936-09-09
Abstract: Ferrous ascorbate is prepared by treating ascorbic acid or its alkali or alkaline earth salts with ferrous salts under slightly acid or neutral conditions.  Ferric salts may be employed provided a reducing agent, such as sulphurous acid, sulphites, thiosulphate or metallic iron, is present or an excess of the ascorbic acid or salt is used. According to the examples: (1) aqueous solutions of ascorbic acid and ferrous chloride are mixed, sodium bicarbonate is added partly to neutralize the liberated acid, and the product evaporated to dryness in vacuo; (2) ferric chloride is added to an aqueous solution of ascorbic acid in excess, the solution partly neutralized with bicarbonate and the ascorbate isolated; (3) aqueous solutions of barium ascorbate and ferrous sulphate in stoichiometric quantities are mixed in a nitrogen atmosphere and the product, after filtration, is evaporated in vacuo.  Tests are described which illustrate the pharmacological activity of the ferrous ascorbate.

Patent GB-455022-A (GB)
Title: Improvements in or relating to textile yarns
IPC: D06M15/39
Filed: 1935-04-04
Abstract: To improve textile yarns before fabric formation, a crimp or crinkle is fixed in the fibres or filaments which constitute or are to constitute the yarn by forming therein a waterresistant highly polymeric organic compound by reaction of an aldehyde within the materials in the presence of an oil or a plasticizer for derivatives of cellulose.  The highly polymeric organic compound is either a synthetic resin formed by reaction of an aldehyde, or a compound formed by the method described in Specification 450,620.  The resin materials may be applied as such or as a water soluble intermediate condensation product. Preferably, the yarn is impregnated before the crimping process. Excess reagents should be removed by squeeze rollers.  If one reagent is gaseous, e.g. formaldehyde, it may be applied after crimping.  Suitable oils or plasticizers which may be employed are lauric, myristic, oleic, palmitic, stearic, ricinoleic acid, or the acids from coconut oil; lauryl, cetyl, oleyl, stearyl, ceryl, and myricyl alcohols; esters of the above acids with lower or higher or polycarboxylic acids.  Salts may be employed such as turkey red oil or the salts of fatty acids with aliphatic amines or oxylalkyl-amines.  If the salt is basic, the reaction of the formaldehyde or similar body is preferably carried out under acid conditions, e.g. by addition of hydrochloric acid.  Derivatives of any of the above bodies may be employed, e.g. the products obtained by their sulphonation or sulphating, e.g. those sold under the Registered Trade Marks "Brilliant Avirol" or "Igepon."  The reaction within the materials may be assisted by catalysts, e.g. acids.  The reagents are preferably applied in solutions in water, organic solvents or mixtures of these. Organic solvents may also swell cellulose derivatives and assist penetration.  The crimping may be effected by rollers which may be heated, or steam may be applied to the materials as they pass through the rollers.  Or a twist may be applied and subsequently removed.  The condensation or polymerization is preferably effected after the insertion and before removal of the twist unless the twist is temporarily set by steam or hot water when the condensation or polymerization may be effected after untwisting. The yarns may be treated to break up the crimp or crinkle, i.e. to render the crimp in some filaments or fibres of the yarn out of phase with the crimp in others, by the methods set forth in the concurrent Specification 455,021.  Specifications 378,054; 424,683, 424,752, 424,830, 424,879, 453,432, 453,433, and 453,434, [all in Group IX], also are referred to.
