Title: Manufacture of compounds of the cyclopentano-polyhydrophenanthrene series
IPC: C07J75/00
Filed: 1937-08-23
Abstract: 501,421. Sex hormones. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 23, 1937, No. 23058. [Class 2 (iii)] Amines of the cyclopentanopolyhydrophenanthrene series are prepared by subjecting to the Beckmann transformation the oxime of a compound of this series having a -CO-CH3 group in the 17-position and hydrolysing the resulting acetylamino compound. The amines thus obtained may be converted into compounds having the character of the male sexual hormones by treatment with nitrous acid to give the corresponding alcohols, which, in turn, may be converted into ketones by oxidation if necessary with temporary protection of any double linkage that may be present. In examples: (1) acetyl-pregnenolone-oxime is mixed with benzene and thionyl chloride, heated, and the residue heated with alcohol and hydrochloric acid to give the hydrochloride of 3-hydroxy-17-amino-androstene which can be purified by treatment with caustic soda, crystallization from petroleum ether and precipitation as the acetate. The 3-hydroxy-17- amino-#<5-6>-androstene when heated on the steam bath with sodium nitrite and acetic acid gives #<5-9>-androstonediol. The latter, on treatment with bromine, glacial acetic acid, and chromic acid gives #<5-6>-androstenedione ; (2) the oxime of 3-acetyl-pregnanolone is similarly converted into the corresponding amine which, upon treatment with nitrite and oxidation, results in androstanedione.

Abstract: 388,069. Sound transmitting and receiving devices. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Thuras, A. L.; 243, Waverly Place, New York, U.S.A.) Aug. 18, 1931, No. 23288. Convention date, May 2. Addition to 333,578, [Class 40 (iv), Telephones &c]. [Class 40 (iv.] An electrodynamic transmitter or receiver of the kind described in the parent Specification is provided with two additional acoustic impedance devices for controlling the movements of the diaphragm, one of these being an auxiliary air damping device such as is described in Specification 382,668, for damping the vibrations of the diaphragm over a narrow band of frequencies in the upper part of the audible range, and the other additional impedance device comprising a conduit which connects the air in the casing of the instrument with the external atmosphere. This third impedance element, which in itself forms the subject-matter of Specification 382,268, serves to increase the movements of the diaphragm in the lower portion of the audible range. The transmitter shown is substantially identical with that shown in Fig. 8 of Specification 382,668, with the exception that the additional feature provided in accordance with this invention consists of a tube 61 which is secured at one end to the annular polepiece 14 and extends into the chamber 53 formed by the casing 52 in which the magnet structure is housed. A plate 33 and washers 31, 32, between which the diaphragm 27 is clamped, are provided with openings 64 leading to the tube 61. The tube is thus open to sound waves impinging on the front of the diaphragm, and conducts a portion of the sound, particularly the lower frequencies, to the . rear of the diaphragm, thereby producing a reinforcing effect. The conduit 61 may extend through the side of the casing 52, instead of communicating with the external air at a place near the periphery of the diaphragm. A diagragm showing an electrical analogue of the mechanical and acoustical vibratory elements of the device is given in the Specification, together with a graph showing the improvement in the response produced by the invention.

Abstract: 1,101,506. Rotary pumps. P.V.L. SALMINEN. May 26, 1965 [Sept. 29, 1964; March 15, 1965], No. 22303/65. Heading F1F. A rotary axially-sliding vane pump comprises a cylindrical pump body 1, Fig. 1, closed by an end-cover 6, Fig. 3, formed with an inlet 9 and an outlet 10 and a partition 11 therebetween projecting into a pumping chamber 8 into and out of which vanes 5 received in slots 4 of a rotor 3 axially-slide. The cover 6 includes an inwardly projecting central plug 7 fitting a bore in the rotor 3 and formed with a cam groove 13 co-operable with cam followers 12 formed one on each side face of a vane 5. The cam groove 13 is provided with slanting surfaces 15, 16 leading to an elevated cam surface 14 parallel to the end-face of the partition 11, which eliminates the necessity of slanting faces on the partition itself. This prevents the forcing of the pumped fluid over the top of the vane and leads it is said to a quieter more efficient pump. When operating a pressure pump channels are provided in the rotor forwardly of each vane in the rotational direction of the rotor so that the pumped liquid can act on both axial faces of the vanes to provide balancing of the vanes. Alternatively grooves may be cut in the leading faces of the vanes or the vanes may be formed with axially extending holes open to the pumped liquid at the cover end of the vanes. When operating as a vacuum pump, vane balancing may be achieved by connecting the bottoms of the slots 4 with each other, e.g., by the removal of packing 18 between the end-face of the central plug 7 and the bottom of the rotor bore into which it fits. The vanes may be made of plastics material.
