Pascal's device for gases

Dating

25 June 1952

The principle of Pascal (1653) is true for the " perfect fluid " and for fluids at rest. This tool allows to check how the pressure in a fluid (here the air, a gas) is transmitted in all directions (other devices also demonstrate that it is transmitted with the same intensity). By pressing the plunger, the level of the mercury (removed for security reasons) in all the pressure gauges rises simultaneously.

The additional indications which integrate the items of the conservation's state have the following meaning: (?) = maybe complete; M = maintenance; P = partial; R = restored; D = used for teaching; NC = not checked; X = impossible to verify.

In order to avoid that instruments' cards without the english description text of the device be directly selected, I added a special filter with which only the complete cards are shown in the menu. Anyhow all the partial english instruments' cards (with instrument's dating, dimensions, state of conservation...) can always be seen even if they haven't the english description text. To read this uncomplete cards is sufficient to click, for example, on an instrument's picture or on the word "View" of the table column called "Card" every time they appear in the other pages of this database.
