Abstract: 634,212. Permutation locks. CAPDEVILA, A. S. April 16, 1947, No. 10069. Convention date, April 17, 1946. [Class 44] A locking mechanism comprises a number of buttons 11 arranged in a ring on a supporting plate 10 to control a corresponding number of pins 36 slidably mounted in apertures 37 in a plate 38 at the rear of the lock. The pins 36 each have a slot 50 which when correctly positioned coincides with the tooth 42 of the corresponding one of a series of members 41 so that the plate 39 carrying the members 41 may be turned to free the lock. The lock is controlled by a sliding bolt 56, Fig. 4, attached to a plate 53 having a slot 52 for engagement by a pin 51 on the plate 39. The pins 36 are each actuated through a rod 26 by a plunger 24 slidably mounted in a bore 23 parallel to the bore containing the button operated member 20, Fig. 3. The member 20 has a spring- loaded pawl 27 engaging teeth 29 formed on the side of the plunger 24 which is therefore displaced by the width of a tooth each time the button is depressed. It is retained against return under the action of the plunger spring by a spring-loaded locking pin 32, Fig. 4, engaging another set of teeth 31 on the innerside of the plunger. The plungers 24 are released to return to their initial positions by retracting the locking pins 32. This is effected by a plate 18 formed on its periphery with a series of camming apertures 57 which engage pins 59 on the locking pins and arranged to turn through a small angle when the knob 17 is turned to release the lock. The locking members 41 are slidably mounted in tubes 40 and formed with teeth 43 on the underside so that their positions may be changed to alter the combination. The teeth are normally locked in position by blades 47 mounted on a disc 46 which may be turned to release the members 41 by means of a key. The members 41 are then slid to new positions by operating the buttons according to the desired combination.

[Class 2 (ii)] [Also in Group XX] A photographic film comprises a cellulose ester support, a cellulose ester photographic layer, and one or more subbing layers therebetween, which layers are compatible with those layers adjacent thereto. All the layers essentially consist of cellulose esters of lower fatty acids of 2-4 carbon atoms. The difference between the apparent acetyl content of the cellulose ester of the support and the average apparent acetyl content of the subbing layer adjacent to it is not greater than 11 per cent.; the difference between the average apparent acetyl contents of any subbing layers adjacent to each other is not greater than 3.5 per cent. ; the difference between the apparent acetyl content of the cellulose ester in the photographic layer and the average apparent acetyl content of the subbing layer adjacent thereto is not greater than 12 per cent. ; the differences between the apparent acetyl contents of substantially all of the cellulose esters, where more than one are present, in each subbing layer are not greater than 9 per cent. The cellulose ester of the photographic layer may be a partially hydrolysed cellulose acetate of 20-28 per cent. acetyl content, and the cellulose ester of the support may have an apparent acetyl content of 38-42 per cent. or it may even be a triacetate. The photographic layer may contain a silver halide. The various layers may contain one or more simple or mixed cellulose esters, e.g. cellulose acetate-propionate or acetate-butyrate. The apparent acetyl content of a cellulose ester used in any of the layers is the total acyl content calculated in terms of acetyl, e.g. in the case of a cellulose acetate propionate, the apparent acetyl is the sum of the actual acetyl and the acetyl which is equivalent to the propionyl. Plasticizers may be incorporated in the solutions from which the various layers are formed. Sensitizing dyes may be incorporated in the photographic emulsion. The solvent mixture for the light-sensitive layer may be a mixture of ethyl alcohol, water, and monoacetin or other plasticizer. Specifications 426,942, 528,107, 528,375 and 550,560 are referred to.
