Patent GB-439046-A (GB)
Title: A method for making moulded articles from impregnated fibrous materials
IPC: D21J1/08
Filed: 1934-05-28
Abstract: Moulded articles are produced by aggregating fibres into ductile structures such as sheets &c. by felting or similar operations and impregnating the ductile structures in a dry state with a solution or emulsion of a binding medium so that the binder is incorporated in the individual fibres, the impregnated structures being subsequently dried and moulded between dies with relative displacement of the constituent fibres.  The fibres may be of animal, vegetable, or mineral origin, preferably ligno or pecto cellulose with an admixture of asbestos fibre if desired. Before, during, or after the felting operation the fibres are treated to remove oils &c. and uncover the fibre skeleton.  The treatment may be a mechanical one, such as is used for textile fibres, or a chemical one with oxidizing or reducing agents &c. After the fibres have been felted and dried, small pieces are punched out of the sheet &c.  These are impregnated with a binder such as natural or artificial resin, oil, bitumen, glue, gelatine, cellulose derivatives, rubber &c., in a hot or cold condition, by dipping, spraying, &c.  The binding medium may give off gases during the moulding operation or substances may be added which generate gas, such as ammonium carbonate.  Alternatively, gas-adsorbing substances such as lime or ferrous oxide may be added.  Fillers, such as china clay, talc, wood flour, &c. may be added to the fibrous material and colours may be included in the binder.  The impregnated material is dried and then moulded, preferably with the application of heat.  The pressing operation may be carried out in stages and metal reinforcements may be embedded in the article.  One or more pieces of impregnated material may be used which are smaller than the base of the article to be produced.  As an example, 1 part of cotton is mixed with 30 parts of water, to which 10 per cent of soda ash may be added, and the whole is treated for 4-5 hours at a temperature of 50 DEG  C.  The fibrous material is rinsed and felted and then impregnated with synthetic resin and moulded as previously described. Hemp may be pretreated with a soap solution containing 100 parts by weight of rosin and 25 parts of sodium hydroxide in 1000 parts of water.

Title: Process for hydrating lime
IPC: C04B2/04
Filed: 1939-06-01
Abstract: 529,481. Slaking lime. CORSON, Inc., G. & W. H. June 1, 1939, No. 16171. Convention date, June 4, 1938. [Class I (iii)] [Also in Group V] Dry, finely divided, hydrated lime is produced by mixing with water in excess in a sealed high pressure cylinder and suddenly releasing the pressure. A slurry formed in mixer 5 (fed by valved pipes from tanks 1 and 2) is delivered into a pressure cylinder 10 through tube 8 having a valve 12. The small percentage of water ordinarily converted to steam may be eliminated by using an initial gas or air pressure so that the hydration proceeds with the water all in the liquid state. When all the lime and magnesia is hydrated the orifice 13 is suddenly opened by the valve 14, and the contents of cylinder 10 are ejected explosively through a venturi opening 17 into a large chamber 18 whence the settled finely divided particles, dried by the rapid evaporation ensuing at the high temperature on the sudden release of pressure, are removed by conveyer system 19 to 21. Blast furnace slag, alumina, or silica may be added before hydration, a slag cement being produced, or the product may be mixed previous to mixing with water with calcined gypsum yielding a lime plaster. In an example the pressure reaches 600lb./sq. inch in 3-4 minutes and falls to 400lb./sq. inch. after 7 minutes owing to heat absorption by the walls. The mass is then ejected at 400-450‹F. and dries immediately.

Title: Improvements in or relating to oligodynamically acting germicidal products
IPC: A61L2/238
Filed: 1935-06-04
Abstract: Powdered germicides for scattering or treating wounds are prepared by impregnating powdered or pulverizable carriers such as silica gel, cellulose or bole with a compound comprising silver oxide and manganese oxides in chemical combination of a salt-like character, preferably silver manganite, and powdering if necessary.  The products can be worked into salves, pastes, plasters, ovules or plugs having oils, fats or salves as their bases.  The carrier may be treated with solutions of silver salts and alkali permanganate and the silver permanganate formed reduced with dextrose, formaldehyde, sulphur dioxide, or by the action of the carrier itself.  Absorbable carriers such as catgut waste may be used.  The impregnated material may be ground wet or dry with addition of protective substances such as colloids, and the products may be mixed with other inert or active powders, or converted into pastilles or the like which are powdered for use. The powdered germicides may be mixed with a salve base or its liquid constituents, for example, by grinding with aqueous or oily liquids with the addition of colloids such as tannin, and other ingredients then added.  The pH is adjusted to that of the body tissues, if necessary, as by addition of buffers.  Specifications 431,656 and 457,785 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 457,785, and the impregnation of suture threads with the silver oxide-manganese oxide compounds.
