Title: An improved electrical instrument for automatic detection of smoke in the atmosphere
IPC: G01N27/12
Filed: 1922-11-07
Abstract: 210,860. Dickinson, H., and Dickinson, A. M. Nov. 7, 1922. Electric alarm systems.-A deposit of smoke on an insulating-medium allows the passage of an electric current to sound an alarm. As shown, thinly covered copper wire 1 is wound upon a zinc, carbon, &c. rod 11, and smoke, absorbed by the thin cover of the wire, partly breaks down the insulation thus allowing the passage of sufficient current from the battery 2 to operate relays 3, 4; arms 7 then close the circuit through a battery 9 and a relay 5 the arm 7 of which closes the alarm circuit. When zinc and copper or other positive and negative pairs are used in the detecting device they form a primary battery when the insulation is broken down and produce sufficient current to influence the first relays. The insulating-element may comprise a strip of fabric &c. between two terminals; or it may comprise a layer of insulating wire wound on a perforated tube, or copper wire wound spirally on fine insulated wire covering one or more carrier rods. The Provisional Specification states that the smoke may deposit on the surface of non-conducting liquids and so complete the circuit, and that a number of detectors may be connected to an indicator board.

Abstract: 508,452. Unsaturated steroid ketones. SOC. OF CHEMICAL INDUSTRY IN BASLE. Oct. 21, 1938, No. 30490. Convention date, Nov. 1, 1937. [Class 2 (iii)] #<4.5> -Unsaturated steroid ketones are prepared by subjecting to thermal decomposition a condensation product of an organic base with a steroid 2-halogen-3-ketone containing no halogen in rings A and B other than that in the 2-position. As starting materials there may be used any 2-halogen-3-keto steroids of sterols, bile acids and the androstane pregnane and oestrane series. The condensation product may be an organic ammonium compound prepared by reaction of the halogen compound with a primary, secondary or tertiary base. The thermal decomposition is preferablyconducted under reduced pressure, but may be done under raised pressure in the presence of an inert gas such as nitrogen. In the latter case a solid or liquid diluent is desirable such as a metal, a metal oxide or a metal salt. Compounds mentioned include aluminium oxide, zinc oxide, copper powder. A suitable liquid diluent is a high boiling point hydrocarbon. As suitable organic bases there are mentioned pyridine, quinoline, dimethylaniline, aniline and aminoethanol. In examples (1) monobromocholestanone and pyridine are refluxed to give a crystalline condensation product which decomposes when heated to about 300 C. in a vacuum. The distillate is extracted with water and from the insoluble portion #<4.5>- cholestenone-(3) is formed; (2) bromandrostandione-3.: 17 is converted into its pyridine addition compound as in example (1). This is then decomposed under reduced pressure to give, #<4.5>-androstene-dione-3 : 17. Other transformations which are referred to as being made possible by the process of this invention are : androstanol-17-one-3 # testosterone, allopregnandione-3 : 20 # progesterone, 3-keto-allocholanic acid # #<4.5>-3-keto-allocholenic acid, 3-keto-aetiocholanic acid # #<4.5>-3-ketoaetiocholenic Acid.

Title: Improvements in or relating to methods of producing aromatic compounds substituted by hydrocarbon groups in the nucleus
IPC: C07C41/30
Filed: 1958-09-30
Abstract: An aliphatic, aralkyl or alicyclic hydrocarbon group is introduced into the nucleus of an aromatic compound by reacting the given compound with an ester of metaphosphoric acid formed in situ from a metal salt of metaphosphoric acid and an aliphatic, aralkyl or alicyclic halide.  Suitable salts of metaphosphoric acid are those of silver, zinc, cadmium, copper, mercury, tin and lead.  The method is suitable for introducing saturated or unsaturated hydrocarbon substituents into the nuclei of benzene, toluene, dimethylbenzene, thiophenene, and methoxy-substituted benzenes and naphthalenes.  The reaction gives rise to para-substituted compounds when the starting-material is a mono-substituted benzene derivative.  In Example 3, a mixture of cyclohexyl iodide, 1,4-dimethoxybenzene and silver metaphosphate is warmed under reflux.  After 3 hours, the reaction mixture is cooled and extracted with ether.  The ether is evaporated from the extract, the excess of reaction components distilled off, and the cyclohexyldimethoxybenzene is distilled in vacuo.  Examples 9 to 14 relate to the introduction of the cyclohexyl group into 1,3-dimethylbenzene, toluene, benzene, 1-methoxynaphthalene, 2-methoxy-naphthalene and thiophene, respectively.  Other examples relate to the introduction of the isobutyl, amyl, isoamyl, n-hexyl, n-heptyl, allyl, benzyl, and cyclohexyl groups into anisole.
