Filed: 1971-09-07
Abstract: 1341719 Stabilized dye images AGFA GEVAERT AG 7 Sept 1971 [10 Sept 1970] 41591/71 Heading G2C In a process for producing stabilized photographic images by imagewise exposure of a photo-sensitive layer accompanied or followed by imagewise production of substances which catalyse the decomposition of peroxidic compounds, the exposed layer is treated with a catalytically decomposable peroxidic compound and a dye precursor which resets with the decomposed peroxide compound and then treating the dye image with a solution of polyvalent ions of at least one metal. These ions react with excess dye precursor to form oxidation stable complexes which prevent dye fogging on storage and obviate the need for rinsing out the dye precursor from the photo-sensitive layer. The ions may be from Group Ib, IIb IIIb IVb Vb VIb VIIb VIII IIa IIIa IVa Va metals and are added to the photo-sensitive layer as aqueous solutions with various anions or as complexes whose stability is less than that of the complex to be formed. The photo-sensitive layer contains substances which are activated by actinic radiation e.g. catalase or peroxidase active ferments, compounds which split off iodine ions or complexes of heavy Group VIb or Group VIII metals with ligands such as mono- or polybasic carboxylic acids. The peroxidic compounds added during processing may be hydrogen peroxide, inorganic peroxides, perborates, percarbonates, persilicates, perphosphates or persulphates organic peroxides, or addition compounds of hydrogen peroxide with amides (e.g. urea), polyhydroxy compounds or amines. The dye precursors may be an amino, hydroxy or amino hydroxy derivatives of isocyclic or heterocyclic aromatic compounds, which may be further substituted. Mixtures of such derivatives may be used or alternatively, substances which do not form dyes themselves but enhance dye formation may be used. Leuco or vat dyes or compounds which give dyes in a secondary reaction are other alternative components in the dye forming reaction. Colour couples may also be used, with catalytically oxidisable colour developers. Exemplified light-sensitive materials are silver halide, ferric ammonium citrate and titanium dioxide and the dye image is stabilized with aluminium sulphate, zinc sulphate and lead acetate respectively.

Abstract: 417,526. Calculating-machines. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Yackley, R. J. ; R. D. No. 3, Seminole Boulevard, Redford, and Hall, R. C. ; 4086, W. Euclid Avenue, both in Detroit, Michigan, U.S.A.) April 8, 1933, No. 10543. Convention date, April 21, 1932. [Class 106 (i).] In a calculating-machine having an adding and subtracting totalizer with transfer tripping means on its wheels, latching means co-operating therewith, a transfer cam arm and a segment moved by said arm to effect positive or negative transfers, a lever is manually movable to prevent transfer between two denominations. The invention is shown applied to the Ellis machine of the type described in Specification 28253/08, [Class 106 (i)]. When a numeral wheel passes through a transfer point in subtraction a cam 38 trips a latch 45 having a detent which releases an arm 53 of the transfer cam 49 and allows the arm to rest against a bar 83. A transfer segment 56 is pivoted to a plate 57 and has a pin 55 engaging a cam slot in the transfer cam 49. When the wheels have been actuated they are returned into engagement with the transfer segment 56 and the bar 83 is moved to the right, the transfer cam 49 rocking anti-clockwise whereby its cam slot acting on the pin 55 actuates the transfer segment 56 to effect transfer. During addition, the latch 45 is moved away from the numeral wheels and another latch 42 lowered into active position by a bar 73. When the latch 42 is tripped the transfer cam is released so that its arm 53 rests against the bar 83. A bar 75 to which is attached a spring 86 controlling the transfer segment is moved to the right when the machine is conditioned for addition, so that upon the subsequent rocking of the cam 49 the transfer segment 56 is controlled by the right-hand branch of the cam slot 55 to effect the transfer. Splitting - machine.-The machine has five denominations and is adapted to be split between the fourth and fifth. For this purpose, a keyboard lever 70, Fig. 7, is pushed forwards and, through a link 65, rocks an arm 60, Fig. 2, having a hooked end which then engages a pin 58 on the appropriate transfer cam 49 and inhibits transfers between the fourth and fifth denominations.

Abstract: 1,082,955. Camera diaphragm mechanism. PENTAGON DRESDEN KAMERA - UND KINOWERKE VEB. Oct. 16, 1964, No. 42293/64. Heading G2A. An electronically controlled camera diaphragm mechanism comprises a plurality of blades 11 mounted on rotatable rings 1 and 2, the aperture defined by the blades being determined by the relative movement of the rings. Ring 1 is provided with a cocking arm 6 which is engaged by a member 7 on ring 2, and is held in a cocked position by a blocking member 8. On closing a contact 22, a sweep circuit 20 is connected to a cell 21, and simultaneously the member 8 is moved by an electromagnet 18 to release the arm 6 so that rings 1 and 2 run down together under the action of springs 3 and 4 until a lug 13 on ring 2 engages a blocking bolt 12; ring 1 runs on alone whilst ring 2 is stationary causing the blades 11 to open. After a time determined by the sweep circuit 20, bolt 12 is moved by an electromagnet 19 releasing ring 2 which again runs down with ring 1 so that the blades do not open further. As bolt 12 is moved out of the path of lug 13 its end pivots a lever 25 which closes a contact 32 which causes the electromagnet to hold the bolt and hence the lever 25 in this latter position; as the lever is pivoted it causes a lug 235 to be released from a claw 26 so that a drive disc 27 of the camera shutter is released, and simultaneously causes clamp 17 attached to the lever 25 to push fluted radially extending lugs 14 and 15 on rings 1 and 2 into engagement with each other and a fixed clamp 16 to prevent the rings moving further and thus maintaining a constant aperture. This condition is maintained until after the exposure has been effected, when the lug 35 on the disc 27 breaks a contact 33 causing the bolt 12 and lever 25 to return to their original positions. The diaphragm is recocked by rotating the arm 6 against the action of springs 3 and 4 until it is held by bolt 8. The aperture defined by the rings during exposure is controlled by the time delay of sweep circuit 20, which in turn is controlled by a photo-cell 30 or a manually adjustable resistance 31, and by the position of bolt 12 which is mounted on a carrier 28 which is set according to an exposure time or other scale 29. If the ambient light is insufficient rings 1 and 2 complete their run down before ring 2 is halted, so that the shutter drive 27 is not actuated and the sweep circuit is discharged due to the arm 6 closing contacts a and b.
