Abstract
Abstract A gas-removing box which may be incorporated in the cooling liquid circuit of an internal combustion engine. For the purpose of rendering the rates of flow of the liquid streams uniform, the box comprises a mass of synthetic foam or like material having open cells whereby it is possible to achieve an excellent separation of the gas or steam bubbles from the liquid notwithstanding the particularly low price of the box.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
241 words
A device combined with a liquid circuit for removing gas from the liquid flowing in the circuit, said device comprising means defining a box, an inlet conduit connected to an upstream part of said circuit and an outlet conduit connected to a downstream part of said circuit, which conduits communicate with the interior of the box and are disposed adjacent opposite ends of said box, the box being arranged to conduct liquid therethrough in a substantially horizontal direction, and baffle means within the box and interposed between the conduits, tHe baffle means comprising a mass of a material which extends fully across the box in a generally vertical plane so as to engage the top bottom and side inner walls of the box transversely of the horizontal direction of flow of said liquid and has a tridimensional reticulated structure which defines throughout the mass of the material interconnecting macroscopic cavities which form sinuous throughway passages in said mass, which passages extend in substantially all directions in said mass, none of which passages constitute a preferential passage, the percentage of said cavities in said mass being more than 90 percent, the mass being arranged to allow passage of liquid substantially horizontally from said inlet conduit to said outlet conduit while causing gas bubbles to rise vertically therewithin and transversely from said liquid, and gas outlet means positioned at an upper portion of said box for discharging such risen gas from the box.
Claim 2

Claim 3
Dependent Claim
32 words
A device as claimed in claim 1, wherein said box comprises two portions and means detachably interconnecting said portions so as to allow access to and replacement of said mass of material.
Claim 4
Dependent Claim
19 words
A device as claimed in claim 1, wherein the average size of the cavities is substantially 2- 5 mm.
Claim 5
Dependent Claim
37 words
A device as claimed in claim 1, wherein in the mass of material the percentage of cavities represents 95- 98 percent of the mass, the cavities having an average dimension of the order of 2- 3 mm.
Claim 6
Dependent Claim
20 words
A device as claimed in claim 1, wherein said material is reticulated synthetic foam having open cells constituting said cavities.
Claim 7
Dependent Claim
13 words

Claim 8
Dependent Claim
13 words
A device as claimed in claim 5, wherein said foam is polyester foam.
Claim 9
Dependent Claim
17 words
A device as claimed in claim 1, wherein said mass is a wad of ''''knitted'''' synthetic filament.
Claim 10
Dependent Claim
41 words
A device as claimed in claim 1, wherein said mass is constituted by substantially uniformly distributed synthetic fibres having no preferential orientation and a binder which coats each one of said fibres and interconnects said fibres at points of contact therebetween.
Claim 11
Dependent Claim
14 words
A device as claimed in claim 9, wherein said binder is a thermosetting resin.
