Title: Steroid compounds
IPC: C07J75/00
Filed: 1955-07-14
Abstract: D 9(11) - Anhydro - cyclopentanophenanthrene compounds are prepared by reacting an 11b -hydroxycyclopentanophenanthrene compound having a hydrogen atom attached to the 11-carbon atom with an alkyl sulphonyl chloride, e.g. a sulphonyl chloride containing 1 to 8, preferably 1 to 4, carbon atoms.  It is preferable to use the sulphonyl chloride in amounts from 1 to 10 mols. per mol. of cyclopentanophenanthrene reactant.  A solvent such as a hydrocarbon or chlorinated hydrocarbon may be used in the process.  The reaction may be carried out in the presence of a tertiary amine and/or an amide of a secondary amine, suitable tertiary amines being pyridine, N-methyl- and N-ethyl-morpholine, a ,g -lutidine, collidine, nicotine, trimethyl-, triethyl- and tripropyl-amine, dimethyl- and diethyl-aniline, and N-heptyl-, N-amyl-, N-butyl-, N-propyl-, N-ethyl- and N-methyl-piperidine, and suitable amides being dimethylformamide and dimethylacetamide. The amine and/or amide may be solvents or a solvent for the 11b -hydroxy-cyclopentanophenanthrene reactant e.g. from 1 to 10 mols. of said amine or said amide or a mixture thereof per mol. of 11b -hydroxy-cyclopentanophenanthrene reactant may be used.  The reaction may be carried out in an organic solvent which does not consist wholly of the tertiary amine and/or amide, e.g. the solvent may comprise a hydrocarbon or chlorinated hydrocarbon such as a mixture of benzene and pyridine, or a mixture of methylene chloride and pyridine.  Other solvents which may be used are chloroform, acetone, propylene glycol and methyl ethyl ketone and mixtures thereof.  Cyclopentanophenanthrene reactants which may be used in the above process are pregnanes and pregnenes, particularly the D 4-pregnenes.  Substituents other than the 11b -hydroxy group which may be present in the steroid reactants are 3,20-keto groups and 3,17a -hydroxy groups.  It is desirable to convert a 21-hydroxy group into an ester thereof before reaction with the sulphonyl chloride. Reactants specifically mentioned are the 21-esters of D 4-pregnene-11b ,17a ,21-triol-3,20-dione-particularly the acetate, propionate, formate, butyrate, benzoate, t-butyl-acetate, hemisuccinate and phenylacetate esters, D 4 - pregnene - 11b ,17a  - diol - 3,20 - dione, D 4-pregnene - 11b  - ol - 3,20 - dione, D 4 - pregnene-11b ,21 - diol - 3,20 - dione - 121 - acetate, acetate esters of D 4 - pregnene - 11b ,17a ,20,21 - tetrol3,20 - dione, D 4 - androstene - 11b  - ol - 3,17-dione, D 4 - pregnene - 11b ,17a ,21 - triol - 3,20-dione, pregnane - 11b  - ol - 3,20 - dione, pregnane - 11b ,21 - diol, 3,20 - dione - 21 - acetate, pregnane - 11b ,17a ,21 - triol - 3,20 - dione, allopregnane - 11b ,17a ,21 - triol - 3,20 - dione, D 5-pregnene - 3b ,11b  - diol - 20 - one, and D 5-pregnene - 11b ,17a ,21 - triol - 3,20 - dione - 21-acetate - 3,20 - bis - ethylene ketal.  In the examples, D 4,9(11) - pregnadiene - 17a ,21 - diol-3,20 - dione - 21 - acetate is prepared. Specification 750,866 is referred to.

Title: A method of colouring glass fibres or other silicious fibres
IPC: C03C25/475
Filed: 1938-07-11
Abstract: 516,826. Glass threads and fibres; colouring glass; softening water. NAAMLOOZE VENNOOTSCHAP. MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. July 11, 1938, No. 20483. Convention date, July 16, 1937. [Class 56] Threads or fibres of glass or other siliceous material are coloured by bringing them into contact for example, by immersion, with a solution containing metallic salts or inorganic dyes. Metallic ions from the solution replace basic constitutents of the glass and produce a colouration within the fibres. After 'the glass has absorbed a metallic ion it may be treated with another solution containing a suitable anion which combines with the metallic ion to form a coloured compound within the glass. For example, the fibres may be treated with a solution of lead acetate and.then with a solution of potassium bichromate to form lead chromate in the glass. Organic dyes, particularly of the basic type, may be used similarly. Examples of methods of treatment are given in the Specification. The Specification as open to inspection under Sect. 91 states that the treatment improves the resistance of the fibres to weathering, and also modifies the electric resistance of the surface. .The fibres also absorb calcium freely from' solutions of calcium, sulphate or calcium chloride, but the action is reversed when the treated fibres are immersed in a solution of sodium chloride. Glass fibres may be used, therefore, for softening water. This subjectmatter does not appear in the Specification as accepted.

Filed: 1944-10-25
Abstract: 580,557. Soldering. SPORING, P. A., and TELEGRAPH CONDENSER CO., Ltd. Oct. 25, 1944, No. 20707. [Class 83 (iv)] In soldering the folded edges of the longitudinal seams of plates, particularly can bodies, molten solder is caused by the action of capillarity to penetrate the seam in a lengthwise direction. The body 11 formed with a longitudinal lock seam is placed in the beaded edge 14 of the base and a bar 15 of combined solder and flux bent to rectangular form is dropped into the can to lie in proximity to the angle between the body and the base. The assembly is then placed in an upright position on the right-hand end of a plate 3 heated by gas jets in a tunnel furnace 1 and is traversed through the furnace by projections on a conveyer 8 driven through reduction gear from a motor 10 so that the solder melts and runs into the joint between the body and base. When the cans emerge from the furnace 1 they tip on their sides over the pulley 9 and slide down a shoot 16 on to the heated floor of a second similar furnace. The seam 12 already heated by passage through furnace 1 is raised to such a temperature that molten solder from the base joint flows up the seam 12 by capillarity. Either furnace may be used separately, if desired, and if the height of the cans is not too great, they may pass through a single furnace in a vertical position to solder both joints.

Abstract: 189,418. Railway Improvement Co., (Assignees of Ransom, H. N.). Nov. 23, 1921, [Convention date]. Capillary-action Lubricators; liquid-level. maintaining.-Lubricant is fed to a bearing from a sealed reservoir 9 by a wick 15 extending through a tube 14 within an inverted well in which the level of lubricant is maintained at a constant level. The well consists of a tube 11 terminating 'near the bottom of the reservoir, the top being covered by a cap 12. After filling the reservoir, the level of oil in the tube 11 is the same as that in the reservoir but rapidly falls to the bottom of the tube, due to the formation of a partial vacuum in the reservoir, and thereafter remains at this level, air passing from the tube to the reservoir. The surface of the oil in the tube is slightly concave, owing to surface tension, the tube 14 is screwed into the bottom of the reservoir and may be adjusted so as to regulate the flow. The end ot the wick is attached to a rod 16 in the tube 11. The invention is described in connection with a railway-vehicle journal-box, the wick 15 resting upon cotton-waste 6 in contact with the shaft. The reservoir is attached to the bearing by a bolt 18 passing through a tube 17. In a modification shown in Fig. 4, the rod 16 extends through the cap 12 and is provided with a collar 25 which may be engaged by a pivoted clip 26 to hold the wick out of the oil to stop the feed. Fig. 5 shows a device for use with electrical machines, in which the rod 16 is normally raised by a spring 29 and carries a soft-iron bar 30 co-operating with a solenoid. When the machine is not running the spring holds the wick out of the oil, but when running the solenoid acts to depress the rod and wick into the oil.

Photo-electric elements 13-16 and 23-26 produce voltages dependent upon the amount of illumination to which they are exposed. When the voltages produced by elements 13-16 exceed those produced by elements 23-26, transistors 3, 4, are rendered conductive whilst transistors 5, 6 are cut off so that the motor operates in one direction. The motor is reversed when the voltages from elements 23-26 are predominant. The photoelectric elements may be mounted on opposite surfaces of a support which is turned by the motor into the direction of incidence of highest illumination on one of the surfaces. The photoelectric elements may be replaced by temperature-sensitive resistors or photo-resistors. In another arrangements, primary winding 35 is energized by amplifier 31 when a potential of predetermined polarity is applied at terminals 30. Alternating voltages are induced in windings 43-46 whereby transistors 5, 6 are rendered conductive and transistors 3, 4 are cut off. The motor is reversed by changing the polarity at terminals 30. The amplifiers 31, 32 may be connected to the output of a measuring bridge. The amplifiers may be associated with receivers having antennµ adapted to receive signals of different frequencies varying in push-pull relation subject to a measured value. A frequency discriminator may be used for controlling the amplifiers.
