IPC: D06M15/15
Filed: 1938-09-30
Abstract: 519,754. Coating-compositions. HINRICHS, W. J. H. Sept. 30, 1938, No. 28524. Convention date, Oct. 6, 1937. [Class 95] [Also in Group IV] Elastic coating compositions, suitable for rendering paper, card, textiles and the like impermeable to oil and organic solvents, are prepared by treating an albuminous adhesive material with ammonia or an amine to render it cold-soluble, treating an aqueous solution of the cold-soluble material with an aldehyde capable of hardening it, and then mixing the solution with an aqueous dispersion of rubber or of a rubber-like material such as a polyvinyl compound, which dispersion may have been stabilized by ammonia. Specified albuminous adhesive materials are skin glue, bone glue, albumen, casein and soya casein. The admixture of albuminous solution and rubber dispersion is effected at a temperature below 50‹C., and preferably between 20‹ and 30‹C., and, after the mixture has stood for a day or longer, a further quantity of the aldehyde, e.g.. formaldehyde, may be added. Containers, made of paper or the like, may be coated with the compositions.

Filed: 1972-06-19
Abstract: 1399623 Measuring capacitance COMMISSARIAT A L'ENERGIE ATOMIQUE 19 June 1972 [24 June 1971] 28533/72 Heading G1U A capacitance 10 is measured by connecting it in the frequency-determining circuit of an oscillator 7, counting (13) the periods of the oscillator output, and measuring the time taken for the count to reach a predetermined number, this time being linearly related to the capacitance. To measure the time, a second counter 20 counts the periods of a fixed-frequency reference oscillator 3, this second count being stopped and displayed when the first count reaches its predetermined number. Facilities are provided for pre-setting the second counter 20 and for enabling it to count either up or down so that the final display may represent either C or C max -C. A variable resistor 5 enables the two oscillator frequencies to be matched in the absence of the unknown capacitor 10, thus nullifying the effects of temperature drift.

Title: Manufacture of unsaturated ketones containing a sterol nucleus
IPC: C07J75/00
Filed: 1935-10-30
Abstract: Monohalogenated unsaturated ketones containing a sterol nucleus are prepared by treating a dihalide of a 3-keto-D <5:6>-unsaturated compound containing a sterol nucleus with a mildly acting agent which binds hydrogen halide. Preferred agents are tertiary bases such as pyridine or dimethylaniline or an alkali salt of an organic acid such as an alkali acetate.  As the initial dihalide there may be used either the dichloride, the dibromide or the di-iodide.  Derivatives of the sterol compounds may also be used, such as esters particularly the propionates and butyrates or ethers particularly the methyl and ethyl ethers.  The parent materials may also be substituted in the 17-position by alkyl groups.  It is stated that in the new compounds the double bond probably stands in conjugated position to the keto group.  Compounds mentioned which may be used to carry out the process of the invention are cholestenone dibromide, dibromo-D <5:6>-androstene-dione and the dibromide of androstene-ol-(17)-one-(3)-benzoate(17).  In examples: (1) a benzene solution of D <5:6>-cholestenone-dibromide is boiled with an aqueous solution of potassium acetate for 6 hours.  The benzene layer is separated, dried and crystallized.  The 6-bromo-D <4:5> cholestenone is recrystallized from alcohol; (2) D <5:6>-Cholestenone-dibromide is boiled in pyridine, acidified, and extracted with benzene.  The benzene solution is worked up as in example (1) to yield the same mono-bromide; (3) a benzene solution of androstene-dione-dibromide is treated with potassium acetate as in example (1) to give 6-bromo-D <4:5>-androstene-dione.  Samples have been furnished under Sect. 2 (5) of (1) 6-bromo-D <4:5> androstene-dione-(3 : 17) made by boiling dibromoandrostenedione with sodium acetate; (2) 6-bromo-testosterone benzoate made by boiling dibromo-testosterone benzoate with sodium acetate.
Patent GB-300824-A (GB)
Abstract: 300,824. Bulmer. Sir J. W. Jan. 2, 1928. Right to Patent relinquished. Cellulose acetate; preparatory treatment of cellulose.-Cellulose to be used for making cellulose acetate is subjected to a preliminary treatment, which consists in immersing it in acetic acid prior to acetylation until the acetic acid is uniformly absorbed and then cooling the mixture until crystallization of the acid has occurred throughout the mass. The acetic anhydride and condensing agents required for the acetylation process are then added either at the low temperature or after the temperature has been allowed to rise. In an example, cotton is steeped in acetic acid of 98 per cent strength for about 24 hours in a container fitted with a device for lowering the temperature to that at which the acetic acid crystallizes and after crystallization has occurred throughout the mass, the acetic anhydride and catalysts are added.
