i- TSra i- TSra
Печатание можно производить и без предварительной обработки парами ацетона или метилового спирта, но дл этого необходимо более резкое клише, срок службы которого при этом меньше, чем при указанной ранее обработке.Printing can be done without pre-treatment with acetone or methyl alcohol, but this requires a sharper cliche, the service life of which is less than with the previously mentioned treatment.
Покрывание слоем бакелита можно производить не при помощи бакелитового лака, а самим бакелитом, изготовленным из составных частей до его затвердени . Тогда можно обойтись без промежуточного нанесени сло масл ного лака или олифы.Covering with a layer of bakelite can be done not with the help of bakelite lacquer, but with the bakelite itself, which is made of its component parts before it hardens. Then you can do without the intermediate application of a layer of oil varnish or varnish.
Предмет патента.The subject of the patent.
1. Способ изготовлени целлюлоидных шкал дл логарифмических линеек, измерительных приборов и т. п. путем печатани шкалы на целлюлоидной пластинке, отличающийс тем, что целлюлоидную пластинку до печатани на ней шкалы, в цел х придани матовости, подвергают действию паров растворител целлюлоида , напр., ацетона или метилового спирта.1. A method of manufacturing celluloid scales for slide rules, measuring instruments, etc. by printing a scale on a celluloid plate, characterized in that the celluloid plate prior to printing the scale on it, in order to impart haze, exposed to vapor celluloid solvent, for example. , acetone or methyl alcohol.
2.Прием выполнени означенного в п. 1 способа, отличающийс тем, что после обработки целлюлоида парами растворител , поверхность его шлифуют.2. Acceptance of the method mentioned in claim 1, characterized in that after treating the celluloid with solvent vapors, its surface is polished.
3.Прием выполнени означенного в п.п. 1 и 3 способа, отличающийс тем, что после нанесени на шкалу краски, содержащей сиккатив, целлюлоидные пластинки сушат и нанос т на их поверхность сначала слой олифы, а затем, после высыхани ее, слой бакелитового лака.3. Acceptance of the above in p.p. 1 and 3, characterized in that after applying a paint containing a desiccant to a scale, the celluloid plates are dried and a layer of drying oil is applied to their surface, and then, after drying, a layer of bakelite lacquer.
4.Прием выполнени означенного в п.п. 1 и 2 способа, отличающийс тем что шкалу покрывают после печати и сушки слоем жидкого бакелита, а затем нагревают пластинку не выше 100° дл затвердевани бакелита.4. Acceptance of the aforesaid in pp 1 and 2, characterized in that the scale is coated after printing and drying with a layer of liquid bakelite, and then the plate is heated to no more than 100 ° to solidify bakelite.
5.Прием осуществлени способа, означенного в п.п. 1 и 2, отличающийс тем, что к типографской краске, которою печатают шкалу, прибавл ют ацетон или метиловый спирт.5. Acceptance of the implementation of the method indicated in par. 1 and 2, characterized in that acetone or methyl alcohol is added to the ink used to print the scale.
