Description

Способы сортировки искусственных зубов из пластмассы и тому подобных изделий по наличию внутренних пустот зже известны. Описанный в авт. св. № 67864 способ состоит в том, что испытуемые издели  помещают в жидкость с удельным весом, несколько меньшим удельного веса материала издели , и отдел ют всплывшие на поверхность жидкости издели , обладающие внутренними пустотами. Хот  этот способ и дает возможность сортировки изделий, но вместе с тем он не дает сравнимой и воспроизводимой характеристики качества изделий по наличию внутренних пустот, а лишь сортирует их, что зачастую  вл етс  недостаточным .Methods for sorting artificial teeth from plastic and similar products by the presence of internal voids are known. Described in ed. St. No. 67864, the method consists in placing the tested products in a liquid with a specific gravity, slightly lower than the specific weight of the product material, and the products that have emerged on the surface of the liquid and have internal voids are separated. Although this method gives the possibility of sorting products, but at the same time it does not give a comparable and reproducible characteristic of product quality by the presence of internal voids, but only sorts them, which is often insufficient.

Предлагаемый способ сортировки искусственных зубов и тому подобных изделий из пластмасс  вл етс  дальнейшим развитием изобретени  по авт. св. № 67864. Этот способ имеет ту отличительную особенность , что позвол ет сравнивать качество нескольких партий изделий по наличию в них внутренних пустот путем изменени  удельного веса жидкости, в которую погружают издели  во врем  испытани .The proposed method of sorting artificial teeth and similar plastic products is a further development of the invention according to the author. St. No. 67864. This method has the distinctive feature that allows you to compare the quality of several batches of products by the presence of internal voids in them by changing the specific gravity of the liquid into which the products are immersed during the test.

Дл  осуществлени  указанного способа применен прибор в форме сосуда, снабженного электроподогревательнОЙ спиралью дл  повышени  температуры жидкости с целью изменени  ее удельного веса.To implement this method, an instrument in the form of a vessel equipped with an electric heating coil is used to raise the temperature of the liquid in order to change its specific gravity.

Схема прибора показана на чертеже .Diagram of the device shown in the drawing.

The vessel 4 having double walls inside which spiral 5 is located is made of a transparent material to observe the behavior of 7 in the liquid.

To determine the comparative quality of several batches of products, for example, artificial teeth made of plastic, by the presence of internal voids they take a predetermined constant number of test items 7, by which they are subsequently judged on the whole lot, and poured into them in 459
