Title: A method of isolating follicle hormones
IPC: A61K31/56
Filed: 1934-01-26
Abstract: Follicle hormones are isolated from urine or preparations made therefrom, or from other starting materials such as placenta extract or extracts from vegetable matter, by first removing volatile phenols, as by steam distillation, then dissolving the residue in a solvent not miscible with water, extracting the solution with alkali hydroxide solution which takes up the hormones but not the neutral constituents, and finally causing the hormones to react with an acylating agent, isolating the acylation product and saponifying it to yield the hormones.  According to an example a hormone extract from mares' urine is steam distilled and dissolved in ether and the ethereal solution is extracted with caustic potash lye.  The alkaline solution is treated with p-toluene sulpho-chloride and the reaction mixture is extracted with ether.  The ether solution is evaporated to remove the solvent and the residue boiled with methanolic potassium hydroxide solution, then largely diluted with water and sodium chloride is added.  The solution is extracted with ether and the ethereal extract is washed and then extracted with potassium hydroxide solution.  The alkaline extract is then acidified to precipitate the hormone.  Specification 401,205, [Group VI], is referred to.ALSO:Follicle hormones are isolated from urine or preparations therefrom, or from other starting materials such as placenta extract or extracts from vegetable matter, by first removing volatile phenols, as by steam distillation, then dissolving the residue in ether or other solvent not miscible with water, extracting the solution with alkali hydroxide solution which takes up the hormones but not the neutral constituents, and finally causing the hormones to react with an acylating agent, isolating the acylation product and saponifying it to yield the hormones.

Title: X-Ray Fluorescent Screen Attachment, for the Localization of Foreign Bodies.
Inventor: BARNICOAT WILLIAM JAMES
Filed: 1918-02-06
Abstract: 122,711. Barnicoat, W. J. Feb. 6, 1918. R÷ntgen-ray and like apparatus.-The fluorescent screen used in X-ray localization is fitted with an attachment for directly reading off the depth of a foreign body. This attachment consists of a scale A and a slider B provided with holes C, the line of the holes being at right-angles to scale A. Through any one of these holes a string E may be passed, the other end of which is connected to a slider D on the frame of the screen. In use, the foreign body is focussed until its image falls on a line FG at right-angles to scale A and passing through the zero thereof, with the right edge of the image touching the left edge of the scale. The slider B is then set with the line of holes C at a mark on scale A which corresponds with the distance between the anti-cathode of the X-ray tube and the fluorescent screen. The X-ray tube is then displaced a certain distance equal to the distance of one of the holes C from the left-hand edge of scale A so that the image of the foreign body still falls on the line FG as shown. The string E is now attached to the corresponding hole C, and its other end is moved until it touches the right-hand edge of the image. The depth of the foreign body is now read off as the intercept of the string E on the scale A.
