Title: Improvements in or relating to the production of artificial filaments
IPC: D01F4/00
Filed: 1930-05-09
Abstract: Keratinous material such as wool, wool-waste, or hair is dissolved in a cuprammonium solution wholly or partly reduced by an agent such as will not cause deposition of copper, and the solution is extruded and formed into filaments which are coagulated in an appropriate fluid. A solution of cellulose in cuprammonia may be added to the keratin solution prior to spinning.  The reduced cuprammonium solutions employed contain copper in the cuprous state or in this and the cupric state, the proportion depending upon the amount of reducing agent added.  In an example keratinous material such as wool or hair is dissolved in a reduced cuprammonium solution made by blowing air through a mixture of strong ammonia and copper turnings maintained at a low temperature, and adding sodium sulphite or sodium hydrosulphite. After all the wool has dissolved, the solution is filtered through metal gauze and it is then mixed with a solution of cellulose, from wood pulp or cotton linters, in cuprammonia.  The solution is extruded into a bath of dilute sulphuric acid in order to obtain artificial filaments.

Patent GB-225585-A (GB)
Title: Process for the production of specific ferment remedies
IPC: A61K39/00
Filed: 1923-06-05
Abstract: Specific remedies against diseases occasioned by foreign bodies such as poisons (including alkaloids), foreign albumens, toxins, and bacteria, are prepared by causing digestive ferments such as pepsin, pancreatin, and trypsin to act in excess on the particular foreign bodies.  It is stated that a combination comprising the ferment and a protective layer of the foreign body, or its products of decomposition, is obtained so that the ferment is not subsequently inactivated by larger quantities of the foreign body. Non-fermentative substances obtained from the gall, brain, renal glands, thymus gland, thyroid gland, &c. may also be added.  The reaction may be carried out by injecting both the ferment or ferments and a foreign body such as diphtheria toxin into an animal and then recovering the antitoxic serum in the usual way, or may be carried out in vitro, a substrate consisting of the inactivated blood serum of the same species of animal as that yielding the ferment being employed in some cases.  In an example carcinoma cells suspended in inactivated blood serum are treated first with an acid solution of pepsin, then neutralized and treated with pancreatin and sodium cholicum (obtained from bovine gall), and the resultant product evaporated to dryness at low temperature or precipitated with alcohol.  A disinfectant which does not act on the ferment, such as formaldehyde or hexamethylenetetramine, may be added as a stabilizer. In other examples tuberculosis bacteria are treated in acid solution with pepsin and a phosphatide and then in alkaline solution with pancreatin and sodium cholicum; diphtheria toxin is treated with pancreatin; and digitalis leaves are treated with pepsin and then with pancreatin.  Keratin may also be treated.  The remedies may be administered by injection or by the mouth.  Specifications 12523/09, [Class 81 (i), Disinfecting &c.], and 5957/13 are referred to.
