A constant calendar rule, within a planned cycle of 36 years, which is formed by a rectangular piece that slides longitudinally inside the existing central notch in another major rule or tablet, in which there are engravings in the lower part, two boxes for the numbers of the days of the month, arranged in a grid of 5 by 7; and in the upper part, seven equal divisions, in which the abbreviations of the months of the year are studied. The recordings of the mobile reglilla are: on the lower edge, twenty-one divisions with the initials of the days of the week repeated three times consecutively, and on the upper edge twenty-three divisions, in which the numbers of the years are distributed up to 36, with the consequent duplicities. This calendar allows, with three known data, to always find the room in question. (Machine-translation by Google Translate, not legally binding)
Perpetual calendar, with automatic regulation of the number of days corresponding to each month (Machine-translation by Google Translate, not legally binding)
Compact equipped with a device that allows the user's initials or the dates of a perpetual calendar to appear through peepholes (Machine-translation by Google Translate, not legally binding)
