Title: Gas lighter
IPC: F23Q2/52
Filed: 1959-12-17
Abstract: 939,182. Gas lighters. R. MOHR, and H. H. QUANDT. Dec. 17, 1959 [Dec. 20, 1958 ; March 3, 1959 ; Sept. 2, 1959], No. 21918/63. Divided out of 939,181. Class 75 (3). A gas lighter comprises a fuel container 4 containing liquefied gas under pressure and a gas channel, a tube 1 extending from an inlet within the container to an outlet outside the container where the gas is ignited, an absorbent thread 6 being disposed in the channel and compressed in a restricted zone of the channel, the inlet to the gas channel and the inner end of the thread being located when the container is held with the gas channel uppermost above the liquid in the container whereby when the container is inverted the inner end of the absorbent thread comes into direct contact with the liquid in the container while when the container is upright it is fed only by gaseous fuel above the level of the liquid in the container. An enlarged flame is obtained by inverting the lighter. The tube 1 passes through a flexible membrane 17 and a washer 19 sealing the lower end of the burner head 9. A part 2 on the tube screws into the container 4. Depressing one end of a lever 30, which pivots in the lighter head part 24 and has a forked end engaging an annular groove 10 on the burner head, causes the external body 5 to rise from an internal body 12 which rises under gas pressure displacing a flexible seating disc 15 in the body 12 from the end of the tube and allows the gas to escape into the chamber between the bodies and fine aperture 11 where a spark from a flint 27 ignites it. A pin 8 in the tube prevents gas collecting therein. A screw 36 at one end of the lever acts as a limiting stop. The friction wheel 32 and two driving wheels 33 are mounted on the lever.

Title: Improvements relating to the production of photographic sound records of the varying
IPC: G11B7/00
Filed: 1931-06-04
Abstract: 384,338. Optical sound - recording apparatus. BRITISH ACOUSTIC FILMS, Ltd., 142, Wardour Street, London.-(Assignees of Poulsen, A. ; 7, Hoyrups Alle, Hellerup, and Petersen, A. C. G. ; 183, Norrebrogade, Copenhagen, both in Denmark.) June 4, 1931, No. 21950/32. Convention date, Dec. 15, 1930. Divided on 384,333. [Class 40 (ii).] A method of preparing photographic sound records of the constant-width and variabledensity type consists in directing on to a film a transversely disposed strip of light adapted to be varied about a mean intensity in accordance with the sound vibrations and having the mean intensity of the light strip varied in inverse proportion to the amplitude of the sounds. Such sound records are adapted for direct reproduction, or several copies may be printed therefrom and records for reproduction purposes may be printed from these as desired. The mean density of the sound record corresponding to the largest amplitude is not less than 50 per cent and at the smallest amplitude the mean density is from 90 to 100 per cent. The apparatus for carrying out the present invention is similar to that described in Specification 384,333, the arrangement being that when the amplitude of the sound is weak the oscillograph mirror e is rotated to such a position that the upper edge of the image g<1> is positioned substantially along the upper edge of the aperture m so that exposure of the film k is considerable, and as the amplitude increases the image g<1> is moved downwardly across the aperture.

Filed: 1928-07-30
Abstract: 321,161. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 30, 1928. Polyhalogenated pyranthrones containing more than 4 halogen atoms are prepared by halogenating pyranthrone or its derivatives in sulphuric acid or a derivative thereof by means of so much halogen or halogenating agents as to produce pyranthrones containing more than four halogen atoms, preferably at elevated temperatures and in the presence of a halogen transferrer. The latter include iodine, sulphur, selenium, iron, manganese, antimony, mercury and their compounds, and they may be employed singly or several introduced simultaneously or successively in the process. Mixed halogen derivatives may be obtained by using halogenated pyranthrones containing 1 to 4 halogen atoms in the molecule as starting materials, or by brominating pyranthrones in presence of chlorsulphonic acid, when simultaneous chlorination mav occur. Products prepared in examples are, (1) pentabrompyranthrone by brominating in chlorsulphonic acid solution in presence of iodine; the product dyes cotton in scarlet shades; (2) pentabrommonochlorpyranthone by brominating in chlorsulphonic acid solution first in the presence of selenium and followed by the addition of antimony; phosphorus or molybdenum may replace the selenium; (3) hexabromdichlorpyranthrone by brominating tetrabrompyranthrone (prepared by brominating pyranthrone under pressure) in chlorsulphonic acid solution in presence of iodine. Specifications 10505/06, 12568/09, and 285,502 are referred to. Reference has been directed by the Comptroller to Specification 282,481.
