Capillary mobile

Abstract

Capillary mobile, characterized in that one side of a square glass basin (picture 1,2) is a few centimeters higher than the other 3 sides.

Description

[0001] Capillary action is commonly known from the observation that if you place a transparent straw or a thin glass tube into a glass filled with water, you can observe that the water level inside the tube or straw rises several millimeters higher than the water level outside. This is called capillary ascension, the rise of water in narrow solid cavities. The opposite is capillary depression, in which liquids such as mercury sink in narrow solid cavities.

[0002] The capillary mobile uses the capillary effect that exists between two glass plates or surfaces (1 and 4) at a short distance to convert the forces generated into movement.

[0003] The capillary mobile consists of a glass water basin (4) with an edge (7) projecting above the water level on one side, as well as two thin glass plates (1 and 5) of equal weight, mounted vertically and movably to it. The glass plates are mounted using a rigid metal rod (Figure 3), the center of which is movably mounted on a metal axis on the raised wall of the water basin. At both ends of which the equally weighted glass plates are mounted in such a way that the lower edge of the glass plate (1) "floating" above the water level only makes contact with the water level when both glass plates are at the same height. The stopper (6) prevents the glass plate above the water basin from submerging below the water level. Due to the mounting on the two metal rods (3) positioned vertically one above the other, both plates are always in a vertical position.The glass plate mounted outside counterweights the glass plate mounted inside and makes it virtually “weightless”, so that the existing, but overall quite weak, capillary forces can be used almost 100 percent only for the upward movement.

[0004] As soon as the water and the lower edge of the inner glass plate (1) come into contact, the water rises into the capillary space between the glass wall of the water basin and the glass plate. The capillary forces then ensure that the distance between the two glass walls decreases, whereby the strength of the capillary force increases and the water penetrates even further into the space between. Due to this capillary force, the glass plate is pulled upwards due to its mounting on the metal rods and pulls itself out of the water. At the highest point (image 2), the underside of the glass plate loses contact with the water surface, and because the stopper and spacer (6) as well as a knob at the lower end of the glass plate prevent the two plates from sticking together completely, most of the water can flow away again and the capillary forces disappear.The plate then sinks back down, the gap increases, contact with the water level is re-established, and the filling of the gap begins again.

Claims

[1] Capillary mobiles, characterized by that one side of a square glass basin (picture 1,2) is a few centimeters higher than the other 3 sides. [2] Capillary mobiles, characterized by that on both sides of the higher pool wall from claim 1, vertically one above the other, there are two horizontal opposite bores or holes with ball bearings or metal rings in them, [3] Capillary mobiles, characterized by that in the 4 bearings or rings from claim 2, there are axes or rods made of metal with a length of a few millimeters. [4] Capillary mobiles, characterized by that on the rods or axles of claim 3 there is one metal rod (3) each with annular openings at both ends and in the middle, in each of which one ball bearing is mounted. [5] Capillary mobiles, characterized bythat in the ball bearings of claim 4, at the ends of the four metal rods (Figure 3), two equally weighted glass plates or discs are mounted with round metal rods of only a few millimetres in length in such a way that they hang parallel to each other at the same height in equilibrium (5,1) [6] Capillary mobiles, characterized by that the lower edge of the glass plate or pane from claim 5 positioned above the water-filled basin is less than 1 millimetre above the water level when both glass plates are at the same height, whereby it comes into contact with the water surface due to adhesion and capillary forces. [7] Capillary mobiles, characterized bythat the side holes in the glass plate floating above the water are drilled a few millimeters higher, whereby the connecting metal rods, each equipped with 3 ball bearings, have a slight upward slope towards the glass plate floating above the water - with the movable glass plates being of the same height. [8] Capillary mobiles, characterized by that on the upper side of the higher glass wall there is a plate made of any material (6), which on the one hand prevents the lower edge of the glass plate (1) from dipping below the water level, and on the other hand, with the interaction of a knob on the inward-facing surface of the glass plate floating above the water, prevents the vertical surface of the pane 1 from adhering completely without a gap to the inside of the upright glass plate of the pool. [9] Capillary mobiles, characterized by that the water basin of claim 1 is almost filled to the brim with water
