Title: A process for the reproduction of multi-colour images by means of colour separation records
IPC: G03F3/00
Filed: 1957-01-17
Abstract: 837,317. Photographic multicolour image reproduction. AGFA A.G. Jan. 17, 1957 [Jan. 19, 1956], No. 1814/57. Drawings to Specification. Class 98(2) In colour separation procedure at least one record is produced in two different colours of opposite gradations (corresponding respectively to the image and non- image portions of a normal record), and is combined with a second separation record comprising a black and white or a coloured image of. main absorption in the same region of the spectrum as one of the colours of the two-colour record but of opposite sign thereto, and the combined records are copied with light of colour within such region of common main absorption on to material sensitive to such light. An example is directed to the procedure using black and white images, in this a multicolour original is copied by green light on to a panchromatic layer containing the 2<SP>1</SP>-methyl-octadecylamino- 5<SP>1</SP>-sulphonic acid anilide of 1-hydroxy-2- naphthoic acid and such is processed to colour and then treated with the addition product of diazotized 5-chloro-2-toluidine and naphthalene-1, 5-disulphonic acid, as by the method of Specification 739,202, to result in cyan negative and orange positive images. These images are registered with a normal yellow separation record made from the same multicolour original and the combination is copied with green light on to an orthochromatic layer, to produce a colour corrected yellow separation record in the form of a positive. The original is copied also with red light on to the same panchromatic layer and this is processed in the same manner, registered with the normally produced magenta separation record for printing therethrough with green light to produce a colour corrected positive magenta separation record. The two-colour cyan separation record is also copied with red light on to a panchromatic layer to make the positive cyan separation record. These final records may be used for production of printing formes, with screening if desired. The process in which the second separation record originally made is also in colour is stated to be particularly advantageous since masking can be effected without necessity of preparing special masks: in this process two two-colour and one single colour intermediate records may be made, (a) green filter for processing to magenta negative and yellow positive, (b) red filter for processing to cyan negative and magenta positive (c) blue filter for processing to blue-violet absorbing positive (such as a yellow containing colour) only, and exposures effected through (a) (c) with blue-violet light for the corrected yellow record, through (a) (b) with green light for the corrected magenta record, and through (b) alone for the cyan record. Many alternatives for the colours of these intermediate records and of the lights by which they are further exposed, for purposes such as influencing gradation, are briefly described in the Specification.

Title: Improvements in deflation alarms for pneumatic tyres
IPC: B60C23/04
Filed: 1925-01-26
Abstract: 228,192. Poitrineau, A., and Gonsard, L. Jan. 26, 1924, [Convention date]. Puncture or deflation, indicating.- A deflation alarm comprises a piston and a striker normally held apart by a spring which, on deflation, actuates the striker to fire a cartridge. In the form shown, the striker A is held in the inoperative position by a pair of balls G which are forced into engagement with a shoulder on the casing M by the stem of the piston D. On deflation, the spring F first raises the piston D, thus allowing the balls G to come away from the wall of the casing, and then forces the head E of the striker into contact with the detonator I. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the ball device is replaced by a leaf-spring the ends of which are normally locked in grooves or notches in the casing wall. When the piston rises, owing to deflation of the tyre, the pressure of the main spring is sufficient. to free the ends of the leaf spring for the actuation of the striker; and also, a further modification in which the striker is normally held in the cocked position owing to the eccentric bore of the piston. On deflation, the piston becomes separated from the striker E, which then assumes axial alignment and is actuated by the spring to explode the cartridge. This subject-matter does not appear in the Specification as accepted.
