Title: Apparatus for use in or in conjunction with cigarette-making machines
IPC: A24C5/20
Filed: 1929-04-26
Abstract: 331,616. Oliver, C. April 26, 1929. Feeding webs.-In means for feeding a paper web to a cigarette machine, a device is provided for indicating the passage of a seam formed by joining the ends of the web at a point of breakage. The device actuates means for stopping the machine, or for rejecting a batch of cigarettes including that formed from the lapped paper, and is arranged not to be operated by a local thickening which does not extend across most of the paper web. The web A passes between a pair of co-operating jaws 28, 33, Figs. 1 to 3. The upper jaw 28 consists of four fingers 28 having longitudinal grooves 30 and pivoted on hinge pins 27 carried by a lever 15, which is pivoted at 14 upon a casing 13 and carries a micrometer screw 16 held in contact with a stop 18 by a spring on the pivot 14. A screwed stud 21 on the lever 15 carries trunnion lugs 23 on which is pivoted a rocking frame 25 carrying the hinge pins 27. These are a slack fit in holes in lugs 29 on the fingers 28, to allow individual fingers to rock about their longitudinal axes, and the pins 27 may also have some rocking movement relatively to the frame 25. The ends 31 of the fingers are bent over bars 32 fixed in the frame 25. The lower jaw 33 is formed in one piece and provided with downwardly bent fingers 34, Fig. 6. It is carried by a fork 35 pivoted at 36 upon an arm 37 with a little freedom for rocking movement. The arm 37 passes within the casing and actuates the device for indicating the passage of a seam, shown in Figs. 9 and 11. An extension 38 of the arm is fixed on a shaft 39 and carries a toothed sector 41 engaging a pinion 42 on a shaft 43 carrying a toothed sector 44. A sector 45 is mounted on a shaft 46 and both sectors 44, 45 engage a pinion 47 on a shaft 48 carrying an insulating sleeve 52, a member 53, and an indicator needle 54 visible through a window in the casing. The member 53 carries contacts 64, 65 for engagement with spring contacts 57, 58 arranged to complete the circuit of a relay switch (not shown) and to stop the machine or to actuate a scoop, rake, or trap door for the withdrawal of a batch of cigarettes, on the passage of a seam between the jaws 28, 33. Owing to the grooves 30 in the fingers 28, and to the play allowed to the individual fingers, the relay switch is only actuated on the passage of a seam extending across the paper web.

Title: Manufacture of new tetrakisazo-dyestuffs
IPC: C09B35/62
Filed: 1949-05-19
Abstract: Tetrakisazo dyestuffs are made by coupling one mol. of 5 : 51-dihydroxy-2 : 21-dinaphthylamine-7 : 71-disulphonic acid with one mol. of the diazo compound of <FORM:0662253/IV (c)/1> and one mol. of the diazo compound of R1-N= N-R2-NH2; R and R1 are benzene residues containing a hydroxyl and a carboxyl group ortho to one another and R2 is a benzene residue in which the amino group is para to the azo group and which contains an alkoxy group ortho to the amino group; R, R1 and R2 are all free from sulphonic acid groups.  R may be 4-hydroxy-3-carboxy-phenyl or the 5- or 6-methyl derivatives thereof or 2-hydroxy-3-carboxy-5-methyl-phenyl; R1 may be 4-hydroxy - 3 - carboxy - phenyl; R2 may be 4 - amino - 3 - methoxy - phenyl, 4 - amino - 2 : 5-dimethoxy - phenyl, 4 - amino - 2 - ethoxy - 5 - methoxy - phenyl, 4 - amino - 2 - methoxy - 5 - ethoxy-phenyl or 4-amino-2-methyl-5-methoxy-phenyl.  The diazotization of the aminoazo compounds is preferably carried out by mixing the amine with alkali and nitrite and then adding acid. The coupling of the two diazo compounds may be carried out simultaneously or successively; in the latter case the second coupling may take place at a higher pH than the first.  The dyestuffs are suitable for dyeing or printing cellulosic material, e.g. cotton, linen, artificial silk or staple fibres of regenerated cellulose.  They may be coppered on the fibre or partly on the fibre and partly in the dyebath, e.g. with a complex copper tartrate (cf. Specification 455,274).  Alternatively, the dyed or printed material may be treated with an aqueous solution of a copper compound (e.g. cuprammine acetate) which contains a basic condensation product of formaldehyde with a substituted guanidine (e.g. dicyandiamide) or a compound convertible thereto (e.g. cyanamide).  Examples show the preparation of the dyestuffs and the dyeing of cotton therewith.  Specifications 452,326 and 559,680 and French Specification 918,737 are referred to.  Monoazo dyestuffs of the formula <FORM:0662253/IV (c)/2> where R is as above, are prepared by coupling diazotized 2-nitro-5-amino-benzoic acid with salicylic acid or a substituted salicylic acid and reducing the nitro group. Monoazo dyestuffs of the formula R2-N= N-R2-NH2, where R1 and R2 are as above, are made by coupling a diazotized aminophenol-o-carboxylic acid with an o-alkoxyamine of the benzene series.  The latter may be coupled in the form of its o -methane-sulphonic acid.
