Title: Process for the manufacture of azodyestuffs
IPC: C09B43/132
Filed: 1935-02-08
Abstract: Azo dyes are prepared by condensing an aminoazo dye of the type A--N=N--B--NH2 wherein A and B are aromatic radicles of which A may contain a further azo linkage and wherein the amino group of the radicle B is in o-position to the azo linkage, with a nitroaroyl chloride and reducing the nitro group to the amino group.  These products or similar products obtained by repeating the condensation several times may be converted to other azo dyes by diazotization and coupling, which may be followed by further condensation with a nitroaroyl chloride, reduction, diazotization and coupling; these further diazotizations and couplings may be performed in substance or on the fibre.  In all cases the products give dyeings which are dischargeable in alkaline or neutral solution.  In examples: (1) o-aminoazobenzene-3<1>-sulphonic acid is condensed with p-nitrobenzoyl chloride and reduced by means of sodium sulphide and again aminobenzoylated; this product dyes cotton yellow shades which on development with 1-phenyl-3-methyl-5-pyrazolone yield a yellow shade and with b -naphthol an orange shade; (2) o-aminodisazobenzene-4<1>-sulphonic acid is condensed with p-nitrobenzoyl chloride and reduced; it dyes cotton reddish yellow shades which on development with 1-phenyl-3-methyl-5-pyrazolone yield a yellow shade and with b -naphthol an orange shade; (3) the p-aminobenzoyl-o-aminoazobenzene-3<1>-sulphonic acid of (1) is diazotized and coupled with 2-(p-aminobenzoylamino)-5-naphthol-7-sulphonic acid to give a product dyeing orange-red shades, changed by development with b -naphthol to a reddish-orange; using instead 2-(m-aminobenzoylamino)-5-naphthol-7-sulphonic acid a similar dye is obtained but which yields on development on the fibre with b -naphthol more yellowish-orange shades; (4) p-aminobenzoyl-o-aminoazobenzene-3<1>-sulphonic acid is diazotized and coupled with 1 - (3<1> - aminophenyl) - 3 - methyl - 5 - pyrazolone; the product dyes the fibre greenish-yellow shades which are unchanged on development with 1-phenyl-3-methyl-5-pyrazolone, while on development with 1-(p-aminophenyl)-3-methyl-5-pyrazolone a reddish-yellow shade is obtained; the m-aminophenylmethylpyrazolone may be replaced by 1-phenyl-3-methyl-5-pyrazolone to give a dye yielding greenish-yellow shades; (5) the azo dye from 2-nitronaphthalene-4.8-disulphonic acid and o-phenylenediamine prepared according to Specification 451,673 is converted to the p-aminobenzoyl derivative as described in (1), diazotized and coupled with 2-(m-aminobenzoyl-m-aminobenzoyl)amino-5-naphthol-7-sulphonic acid; the product dyes yellow shades and may be developed on the fibre with b -naphthol; acetyl-J-acid may be used in place of the aroylated-J-acid.  Specifications 341,898 and 351,322 also are referred to.  The Specification as open to inspection under Sect. 91 comprises the conversion of the aroylated o-aminoazo dyes into other derivatives in a manner known for aminoazo dyes and instances the conversion into ureas or thioureas, but this subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a roll film photographic camera
IPC: G03B19/04
Filed: 1941-04-11
Abstract: 543,451. Roll-film photographic cameras. KODAK, Ltd. (Eastman Kodak Co.). April 11, 1941, No. 4873. [Class 98 (i)] In a roll-film camera in which the film-winding means are automatically latched each time a fresh exposure area is in exposure position, the latch being prevented from operating. after a predetermined number of exposures by an exposurecounting mechanism so that the film trailer may be wound on to the take-up spool, the exposurecorrecting device may be pre-set for a selected number of exposures corresponding to the number accommodated by different films. The invention is described as applied to a camera having the interlocked film-winding and shutter-operating means described in Specification 543,450, in which a disc 36 frictionally driven from a gear 34 geared to a film-measuring roll makes one revolution during each winding operation, at the end of which a lug 45 on a pivoted arm 42 falls into a slot 46 in the edge of the disc and so engages a gear 31 secured to the winding spindle 30, which is thereby locked. The exposure-counting device comprises a disc 61 carrying numerals visible through a window 61a, the disc being advanced one numeral at a time by a Geneva gear 62 operated by a pin 64 on the disc 36 at each revolution of the latter, On winding the film after the last exposure a pin 67 on the gear 62 rocks a spring-pressed lever 68 so that its end comes into the path of a pin 71 on the friction-driven disc 36, which is thereby prevented from completing a full revolution so that the lug 45 cannot enter the slot 46 and engage the gear 34 to lock the film-winding shaft, as shown in Fig. 10. Hence the shaft 30 may be rotated to wind off the backing paper of the film until the first numeral appears in the usual inspection window in the camera back. The hollow spring-pressed spindle 66 carrying the disc 61 and gear 62 is then depressed to disengage the gear 62 from the pin 64, and is then rotated to show the numeral 1 at the window 61a. The latter movement carries the pin 67 out of engagement with the lever 68, which then rocks and frees the pin 71. Slight further rotation of the winding knob brings the notch 46 into engagement with the lug 45, which then engages the gear 34 and locks the winding-shaft. In order that the device may operate with films accommodating different numbers of exposures (in the case shown, eight and six), the Geneva gear 62 is rotatable on the spindle 66 to a degree limited by the engagement of prongs 62b on the former with shoulders 66b on the latter, thus altering the position of the pin 67 in relation to the numerals on the dial 61. The adjustment is made by rotation of the spindle without depressing it, so that the gear 62 is locked against rotation with it. Dimples 85a on a spring washer 85 enter one of two pairs of corresponding depressions of the gear 62 to retain it in either position of adjustment. The window 61a comprises a plain and tinted portion, the numerals appearing below these two portions respectively in the case of eight and six exposure films.

In the form shown, the sleeve b and the collar c are each made in two halves which are bolted together. The piston e is constrained by a light spring to abut against the end of a screw h passing through a boss g on the collar c. The cylinders are connected by metal piping k, k<1> to the opposite ends of a glass capillary tube l. The cylinders and the tube contain a liquid the movement of which when the shaft twists is rendered visible by a plug m of mercury in the tube l. A scale, (not shown), is mounted in proximity to the tube l and is provided with a cursor fitted with an eye-piece and an electric sparking device which gives a spark during every revolution of the shaft. In a modification the tubes k, k' are fixed to the ends of a U- tube partly filled with liquid. This moves in opposite directions in the legs of the tube the distance between the free ends giving the required reading. In this form, the sleeve is conical and diaphragms are used instead of pistons.

Abstract: 1,261,963. Coin testing. AUTELCA A.G. 29 Jan., 1969 [5 Feb., 1968], No. 5038/69. Heading G4V. A coin tester comprises a longitudinallyslotted coin shoot 1 surrounded by an induction coil 3 of an oscillator circuit 5 whose signal is temporarily changed by the passage of a coin, such that the acceptance of the coin depends on the change of signal. The tester identifies two different coin denominations, using two coils 3 and 4, connected to oscillators 5 and 6, and monostable multivibrators 9 and 10, respectively. Passage of a correct coin causes the corresponding oscillator to stop oscillating, whereupon its multivibrator supplies an extended pulse. The pulse from multivibrator 9 continues until the coin has passed coil 4, and the pulse from multivibrator 10 has at least twice that length. The former pulse blocks an inhibit gate 12, and is also differentiated at 14 and inverted at 15 so that the peak occurring at the end of the pulse reaches an inhibit gate 17 after the coin has passed coil 4. If gate 17 has not been blocked by the coin having stopped the oscillator 6 oscillating as well as the oscillator 5 the peak passes the gate to signal coin acceptance. When oscillator 6 is stopped oscillating it sends an accept signal through gate 12, unless it has been blocked by the coin stopping the oscillations of oscillator 5. The longitudinal slot (not shown) of the shoot extends from above coil 3 to below coil 4, and may be filled with insulating material.
