Patent GB-924535-A (GB)
Title: Photographic materials for the silver dyestuff bleaching method
IPC: C09B43/14
Filed: 1961-03-24
Abstract: Dyes are described which contain in their structure the grouping -NH-CO-B-N=N-Py-where B is a benzene residue to which the -CO-and -N=N- groups are linked in meta or para position, and Py is the residue of a 5-pyrazolone linked to the azo group in its 4-position. The dyes may be simple mono-azo compounds obtained by coupling a diazotized aminobenzamide derivative such as N-(m-aminobenzoyl)-2-naphthylamino-4; 8-disulphonic acid, N-(3-methyl-4-aminobenzoyl)-2-naphthylamino-4; 8-disulphonic acid, N-(3-aminobenzoyl)-1-naphthylamine or N-(4-aminobenzoyl)-sulphanilic acid with a 5-pyrazolone such as 1-(31-aminophenyl)-5-pyrazolone-3-carboxylic acid, 1-phenyl-3-methyl-5-pyrazolone, or 1-(41-sulphophenyl)-3-methyl- or 3-carbethoxy-5-pyrazolone. The dyes may have two or more azo groups, however, and may be of the formula Py-N=N-B-CO-NH-R-NH-CO-B-N=N-Py where B and Py are as above and R is an aromatic residue such as a 2;21-disulphodiphenyl residue, and may be prepared by coupling a pyrazolone with a tetrazotized diamine of the formula NH2-B-CO-NH-R-NH-CO-B-NH2, or, where R is -C6H4-NH-CO-NH-C6H4-, by coupling a pyrazolone with a diazotized amine of the formula NH2-B-CO-NH-C6H4-NO2, reducing the nitro group to an amine and treating the resultant amino-azo dyestuff with phosgene. Alternatively, the dyes may have the formula Py-N=N-R-NHCO-B-N=N-Py such as those wherein Py is a 1-(m-aminophenyl)-3-carboxy-5-pyrazolone residue and R is sulphophenyl, and these may be obtained by coupling pyrazolones with tetrazotized amines of the formula NH2-R-NH-CO-B-NH2. Further, bis pyrazolones such as [2;21-disulphodiphenylene 4;41]-bis (3-methyl-5-pyrazolone) may be coupled with diazotized amines of the formula R-NH-CO-B-NH2 where R may be a sulpho-aminophenyl group, for example.  Complex dyes may be formed from any of the above dyes having one or more free amino groups (such as those obtained from 1-aminophenyl-5-pyrazolones) by treating the dye with phosgene to link the molecules together through their amino groups.

Title: Improvements relating to couplers for railway and other vehicles
IPC: B61G1/06
Filed: 1920-04-21
Abstract: 161,837. Adams, Sir H. Goold-, and Mitchell, J. April 21, 1920. Couplings, automatic.-In a Norwegian hook type of coupling, a tight coupling is automatically maintained by means of spring pressure applied to a wedge-shaped member forming part of a locking-bar which engages with the hooked end of the hook, or with an intermediate member engaging the hooked end, or which forms the pivot pin of the hook. The buffing-heads A, B are shown coupled by means of the hook C pivoted at c engaged in the wedge-shaped locking-bar D. A spring E on the reduced end d<2> oi the locking-bar is in compression and tends to draw the wedge surface c<1> into closer engagement with the hook. A notch d<4> cut in the flat side d<1> of the wedge engages with the end f of a gravity latch F when the wedge is withdrawn for uncoupling purposes. The latch may be operated from the opposite side by the handle F'. In a modification, the wedge D may form the pivot pin of the hook C. Instead of the gravity latch F, a rack cut on the wedge D may engage a pawl pivoted on the side of the buffer head B. In another modification, the spring E is placed on a pin supported by lugs under the wedge, one end of the spring bearing against the lug and the other against the wall b<2> of the buffer head. Instead of one wedge-shaped surface on the locking-bar, two oppositely inclined surfaces may be employed so as to enable the bar to be withdrawn from either side. In another modification, the wedge-shaped locking-bar is recessed and two internally projecting pins receive the spring, one end of this, when the bar is in positicn, bearing against the inside surface of the wall b<2> of the buffer head B. The bar may actuate through its wedge surface an intermediate member, which slides horizontally and has a pin at its end for the reception of the hook. In a further modification, the wedge-shaped surface bears against the end of a bell crank lever, the other end of the lever being approximately at right angles and curved to receive the hooked end of the hook C.

Stop-motions.-In a drum winding-machine the bobbin g is carried in a frame f pivoted on an axis f<1> and provided with a bell-crank lever f<11>. A double bellcrank disengaging lever j is pivoted at i on the frame e and is provided with a regulating-screw j<1> and a lateral rod m. The thread passes from the reel b through a guide n<1> on a flexible rod n and through the traverse guide c<1> to the bobbin g. As the bobbin grows the frame f rises and the lever f<11> pushes against the head of the screw j<1> until the lever j overbalances and by means of the cam k raises the frame f and so lifts the bobbin g of the driving-drum h. When the thread breaks the rod n is liberated and strikes against the rod m, thereby causing the frame f to be lifted by the lever j, and the bobbin disengages from the driving-drum, as shown in Fig. 4. The lever j is provided with a stop-rod l which is adapted to engage a notch in the member f<11> and thereby stop the frame f.

Title: Photographic Camera or Shutter Operating Mechanism
IPC: G03B7/16
Filed: 1968-03-07
Abstract: 1,182,053. Photographic shutter combined with a flash device. HATTORI TOKEITEN K. K. March 7, 1968 [March 7, 1967], No.11188/68. Heading G2A. In a photographic camera including a flash device, an obstructing member for preventing or permitting initiation of flash is controlled by an electromagnetic member included in an electric circuit. Daylight exposure. Initial downward movement of camera release 1 closes a power source switch S1 forming the circuit of Fig. 2 into a brightness detecting circuit. If the scene brightness as measured by photo-resistor 61 is sufficient for daylight exposure, transistor 65 conducts and 67 is cut off, the coil 33 of electromagnet M1 is not energized, hence lever 14 may rotate clockwise when pin 15 on an arm thereof leaves surface 10 of the camera release, and this allows anti-clockwise rotation of levers 38, 48 so that projection 50 on lever 48 engages projection 25 on a guide number selecting member 70 which is therefore locked. On further downward movement of camera release 1, lever 14 is rotated anti-clockwise to re-engage coil 34 of M1, and switch S2 tripped to form the circuit into a delay circuit where delay is controlled by the photo-resistor 61. Transistor 66 is cut off, transistor 67 conducts, coil 33 is energized, lever 14 is held, and pin 24 on release 1 rotates a lever 47, releasing abutment 44, so that shutter ring 40 rotates and shutter blades 39 open, switch S3 being opened simultaneously. Hence capacitor 62 is charged until its voltage is sufficient to make transistor 66 conduct, transistor 67 is cut off, the coil 33 deenergized, lever 14 is released, and surface 43 engages a pin 41 on ring 40 to close the shutter blades. Flash exposure. If illumination is insufficient for daylight exposure, transistor 67 is conductive lever 14, and hence levers 38, 48 are held, and member 70 is allowed to move downwards sufficiently to operate switch S4, which switches a constant resistance 59, Fig. 2, into the delay circuit instead of the photo-resistor 61. Pointer 88 on member 70 now indicates FLASH on the indicator and a flash exposure is accomplished in a manner similar to that described above. In an alternative circuit embodiment Fig. 3 (not shown) a flash discharge device is used. Faulty operation e. g. low battery voltage or faulty flash bulb contact in its socket is monitored by electromagnet M2 which releases under such conditions, allowing lever 97 to pivot towards member 70 and prevent its downward movement to the FLASH position. Lever 1 remains free to move down to permit operation of a long daylight exposure. Alternatively a lever 101 may be provided which moves with lever 93 so that its end 107 blocks member 1 and inhibits altogether the taking of a picture.
