Title: A process for the preparation of azulenes
IPC: C07C5/373
Filed: 1954-09-17
Abstract: Azulenes are prepared by passing polycyclic hydroaromatic hydrocarbons rich in hydrogen, particularly perhydrogenated polycyclic hydrocarbons in the vapour phase in admixture with an inert diluent over a catalyst at temperatures in the range of 350-650 DEG  C., preferably at 570-630 DEG  C.  The catalyst may be an oxide of the 1st to 4th group of the Periodic System to which oxides or other compounds of metals, e.g. of the 6th to 8th group of the System may be added.  The diluent may be steam or an inert gas.  Preferred hydrocarbons are dicyclopentadiene, tetrahydrodicyclopentadiene, decahydronaphthalene and its alkyl and aryl derivatives and perhydroacenaphthene.  In examples the catalyst consists of a mixture of zinc oxide, aluminium oxide, calcium oxide, magnesium oxide, potassium chromate and potassium sulphate and the products consist of azulene, methyl azulene and dimethylazulene.
Patent GB-270293-A (GB)
Title: A process for producing insoluble colouring materials in a state of fine dispersion
Filed: 1927-04-25
Abstract: 270,293. I. G. Farbenindustrie Akt.- Ges. April 28, 1926, [Convention date]. Emulsions, making. - In the production of solid insoluble colouring materials in, or conversion of such materials into a state of fine dispersion, trihydroxyethylamine is used as an emulsifying agent in association with gelatinizable substances or water-soluble gums. Glue, gelatine, casein, agar-agar, gum arabic, hydrolyzed starch or the like may be employed as gelatinizable substances or gums. The process is applicable to inorganic or organic solid insoluble colouring materials, e.g. pigments, lampblack, or blanc fixe, and may be employed in grinding organic pigments with heavy spar or the like. In one example, the yellow pigment obtained by coupling diazotized 5-nitro-4-toluidine and acetoacetic anilide is ground in the dry state with powdered glue and trihydroxyethylamine; the product when made into a paste with water forms highly-dispersed suspensions which may be used for staining paper pulp or printing wall-papers. The glue may be replaced by other of the substances mentioned above, and the dispersing substances or their solutions may be added to an aqueous paste of the pigment which is then dried and ground. The subsequent grinding may be omitted if the paste is dried in such a manner as to yield the dried product in powdered form. In another example, a mixture of glue and trihydroxyethylamine, dissolved in water, is added to an alkaline solution of #-naphthol, which is then coupled with diazotized p-nitraniline, the pigment is precipitated in finely-divided form. The process may also be carried out in the presence of the usual substrata. Specification 258,551 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the replacement of the trihydroxyethylamine by soaps, saponines, turkey-red oil, cholates, sulphite cellulose waste liquor, or the sodium salt of benzylaniline sulphonic acid or of alkylated, e.g. propylated or butylates naphthalene sulphonic acids, and the invention is applied to solid materials in general, sulphur being additionally specified. This subjectmatter does not appear in the Specification as accepted.

A toy gun or pistol comprises a clockwork mechanism for periodically cocking and releasing a hammer which co-operates with an anvil to fire caps on a strip drawn on to the anvil by an intermittent feed mechanism operated by movement of the hammer. As shown, an axle 3 carries a pawl 6 of which portions 8 may engage spokes 7 of a main gear wheel 13 provided with pins 14. A spiral driving spring 1 is connected to the axle 3 and is wound by means of a knob 5, a governor 67 being driven via gears 62, 64 and 66. A bell-crank lever pivoted at 18 and urged anticlockwise by a spring 24 includes a hammer 17 adapted to engage a cylindrical anvil 19 having a ratchet 23; a pawl 21 pivoted on the hammer 17 co-operates with the ratchet. The other arm of the bell-crank lever consists of an arm 16 engageable by the pins 14 and having a hook portion 50 for engagement by an elongated hook 48 which is rotatable by a trigger 46. The gun is " loaded " by inserting a roll of caps in a housing 1c, the end of the strip of caps then being inserted between the anvil 19 and a spring-urged pressure wheel 33. After winding the spring 1, pressure on the trigger releases the hook portion 50 from the hook 48 and the gear wheel 13 is allowed to rotate, the release of the arm 16 each time a pin 14 passes it allowing the hammer 17 to detonate a cap on the anvil 19. Movement of the hammer away from the anvil after each firing stroke causes the anvil to be rotated by the pawl and ratchet such as to bring the next cap into the detonating position. The gun continues to operate until the trigger is released, the hook and hook portion 48, 50 then being re-engaged and rotation of the gear wheel 13 prevented. If the gun is to be used with a cap strip which is perforated at intervals, the anvil may be provided with sprocket pins for engagement with the perforations.

[Also in Divisions B2 and C3] Shaped structures such as fibres and films are formed from an elastomeric composition comprising (A) from 50-90% by weight of a cross-linked base elastomer containing at least 75% by weight of units of one or more C 2 -C 8 - alkyl acrylates or at least 75% by weight of a mixture of such acrylate units and units of ethylene, propylene and/or isobutylene and (B) from 50-10% by weight of reinforcing polymer dispersed through the base elastomer, the reinforcing polymer containing (1) units of at least one halide monomer selected from vinylidene chloride, fluoride, or fluorochloride and vinyl chloride or fluoride and (2) 0-12% by weight of units of one or more other monoethylenically unsaturated monomers; said base elastomer being derived from a monomer mixture containing at least 0À1% but less than 0À5% by weight of at least one ethylenically unsaturated monomer containing at least one radical effective to cross-link the base elastomer by a reaction activated separately from the polymerization reaction. Preferably, the shaped structure is heated to a sufficient temperature to at least partially melt the reinforcing polymer, and then the temperature is lowered below the melting point of the reinforcing polymer whereby said polymer recrystallizes. To prepare the fibres (films can be obtained analogously) the elastomeric composition, in latex form with any desired additives, is simultaneously spun and coagulated using the process described in U.S.A. Specifications 2,869,977, 2,914,376, and 2,972,511; or alternatively the latex may be dry spun as described in British Specification 853,483. Monofils or multi-filament tows may be produced by the spinning process. After shaping, the fibre or film is cured, generally in the presence of a cross-linking catalyst, by heating to a temperature of 75- 220 C. In one embodiment, the fibre (or film) can be partially cured, stretched, and further cured to completion in the stretched condition; alternatively stretching (up to 300%) can be effected after curing. The fibre (or film), before, during or after stretching, can then be subjected to the melting/recrystallising procedure described above. The stretching may be effected by jet stretching, or the fibre can be stretched while passing from the godet on to the drying rolls. Curing may take place on the drying rolls or while the fibre is being drawn through a steam chamber or other heating device. The final stretch-curing operation can be carried out by winding the fibre on a bobbin under suitable tension, and effecting curing on the bobbin. The melting/recrystallizing, preferably conducted under stretch, may be effected on the bobbin, on a heated roll or oven or other temperature controlling device. After recrystallizing, a relaxing step may be used, and crimned filaments obtained.
