Abstract: 918,164. Bending tubes. LANGMATZ G.m.b.H. Sept. 28, 1961 [April 28, 1961], No. 34968/61. Class 83 (4). Apparatus for bending tubes comprises a straight guide cheek driven in the longitudinal direction, a curved single cheek having means to clamp an end of a tube thereto to be bent to this curve, the straight and curved guide cheeks having approximating semicircular cross-section and having means such as co-operating teeth or pin-and-hole means such that the straight guide cheek moves the curved cheek, and means for pressing the curved cheek against the straight cheek. A tube 16 to be bent to the shape of a curved member 9 is clamped at one end thereto by means 17. The member 9 is pressed against a straight member 8 by a roller 13 urged by means 4. The member 8 is backed up by a roller 5, and is moved longitudinally by a chain 7 driven by a motor. Teeth 10 on the member 9 engage recesses 11 in the member 8 so that the member 9 is driven past the roller 13 and the tube 16 is bent up against the member 9. After bending the member 9 is retracted from the member 8 by fingers 19 and the bent tube is released. A conical tube may be bent.

Title: The manufacture of oestrogenous products
IPC: A61K36/00
Filed: 1934-12-06
Abstract: Oestrogenous products are obtained from the tubers of the plant Butea Superba, or from other parts of plants of the genus Butea, by extraction with water, dilute aqueous acetone or alcohol, or aqueous salt solutions.  Such extracts, or those obtained in accordance with the parent Specification, may be freed from accompanying sugar and sugar-like impurities by further extraction with solvents, such as methyl or ethyl alcohol or acetone, which do not dissolve the sugars; or by salting out the active substances from aqueous solution by means of ammonium sulphate or other salts, whilst leaving the sugars in the mother liquor; or by a combination of these processes. Saponins may be removed from the extracts by solution in solvents, such as ether, or ethyl acetate, which do not dissolve the saponins. A further purification may be obtained by distributing the extracted products, preferably after purification as above, between aqueous alcohol and benzene, the active substance passing into the aqueous alcoholic solution.  Examples illustrating the various processes are given.  The purified product may be crystallized from alcohol.  It is stated to melt at 272-276 DEG  C. and to have several hydroxy groups in the molecule.

Patent GB-343921-A (GB)
Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08L7/00
Filed: 1929-11-25
Abstract: Materials for making e.g. golf ball shells &c., and having physical properties resembling those of guttapercha, and which can be used as substitutes therefor are prepared by mixing aqueous dispersions of rubber and the like with aqueous dispersions of albumens other than h moglobin in such proportions that the albumin content lies between 25 and 75 per cent on the dry rubber-albumen content.  The most suitable albumen is commercial blood serum.  Substances tending to inhibit the coagulation of the albumen, e.g. ammonia are preferably added.  The mixture thus obtained is then evaporated at temperatures preferably not exceeding 100 DEG  C.  The mixtures may be dried in open moulds or may be deposited on formers by dipping, spraying, or electrophoretic means.  The products are capable of being softened by heat and moulded.  The degree of toughness of the product is influenced largely by the alkalinity of the fluid mixture, and by the choice of the proportions of the two main ingredients.  Example.-40 parts by weight of latex containing 24 parts of rubber and 0,25 parts of ammonia are mixed with 60 parts by weight of a colloidal solution containing 20 parts of commercial blood serum albumen and 1 part of ammonia.  The mixture may be dried in shallow trays at a temperature not exceeding 100 DEG  C. to produce sheets, or a golf ball centre wound with rubber thread may be dipped in the mixture referred to above and allowed to dry.  Successive coatings may be applied. Specifications 219,635, 290,313, and 343,922, [all in Class 70, Indiarubber &c.], are referred to.
