Title: Improvements in means for selecting a record for transfer from the magazine, in magazine gramophones
IPC: G11B17/26
Filed: 1921-07-25
Abstract: 181,024. Soc. des Phonographes Automatiques Bussoz Freres et de Vere. April 8, 1921, [Convention date]. Cent action, mechanical - connection; phonographs. - The recordselecting device of an automatic gramophone is operated during the initial movement of the hand-crank 28 which is freed by the insertion of a coin in the slit 25. The hand-crank carries a slotted disc 27 to receive the coin from the slit 25, which coin, resting upon a sliding member 37 projects from the disc. When the crank 28 is turned, the coin lifts a lever 30 to remove a stop 31 from a projection 32 and operate a lever 34<a> to rotate the shaft 14 of the selecting-device. The coin is ejected by the engagement of a pin 39 on the slider 37 with a fixed cam 40.

Title: N-aryl-azo sultams and a process for their production
Filed: 1954-05-26
Abstract: The invention comprises N-arylazo-sultams of the formula <FORM:0760632/IV(b)/1> where X is hydrogen or methyl and R is a saturated aliphatic hydrocarbon residue of 3-4 carbon atoms.  These are made by reacting a benzene or toluene diazonium salt (e.g. chloride or sulphate) with the appropriate sultam, preferably in the presence of one equivalent of alkali metal hydroxide per equivalent of sultam.  The diazo solution is preferably 0.3-0.6 molar and the alkaline sultam solution 2-4 molar, the former being used in 5-25 per cent excess over theoretical.  Examples are given of the production of N-benzene - azo - a  - methyl - g  - propane sultam and N - (p - toluene - azo) - a  - methyl - g  - propane sultam. The starting materials are obtained by cyclizing alkanesulphonic acid derivatives, e.g. (1) amino-alkanesulphonyl chlorides with alkalis; (2) chloro-alkanesulphonamides by heating; or (3) oxyalkanesulphonic acids with ammonia.  g -Propane sultam and g -butane sultam are mentioned as suitable starting materials. Mixtures of isomers may be obtained and converted into corresponding mixtures of N-arylazo-sultams.

Abstract: 1,150,433. Ornamenting. A. T. RANSON (Owens-Illinois Inc.). 14 April, 1966, No. 16313/66. Heading B6G. A method of decorating an article of glassware comprises applying a thin adhesive film to a surface zone of the article, drying said adhesive, screening a layer of resist having a predetermined design over the adhesive film, grit blasting over the suface zone to cut the design and then removing the adhesive and resist thereby to provide said article with a surface cut decoration thereon, said decoration corresponding with said predetermined design. As described, the adhesive film 8 is of polyvinyl pyrrolidone which is applied by roller application, dipping or spraying; the adhesive film is dried after application by infra-red heating or other suitable means and then the resist which, as described, is a polyvinyl chloride plastisol, is silk screened on to the adhesive film, the coated article then being placed in an oven for six minutes at 400‹ F. to fuse the plastisol to the article; alternatively an infra-red heater can be used; the grit blasting is carried out by using a nozzle and the resist coating and adhesive film is then removed from the tumbler by soaking or agitating hot water over the resistant film to cause them to peel away. In a modification when it is desired to produce a deep cut, two separate coatings of resist are applied to the adhesive film; two separate layers of resist can also be used when it is desired to make cuts of different depths. A coloured ceramic decoration can be applied to the article which is then heated to fire the ceramic before the adhesive film is applied. The method can be applied to articles other than of glass.
