A computer-implemented method for measuring the three-dimensional geometry of a mineral glass-based glazing during or just after a temperature shaping operation. The method implements digital processing and calculations, based on the principles of stereocorrelation, of digital images of a random light pattern projected onto the surface of a transparent glazing. It makes it possible in particular to determine the shape or the three-dimensional geometry of a transparent glazing, the surface of which not be totally opacified and/or which radiates under the effect of temperature.

A monolithic membrane-type filtration structure for filtering liquids, includes a support formed of a porous inorganic material of permeability K, the support having a tubular overall shape with a main axis, an upstream base, a downstream base, a peripheral wall delimiting an internal part and a plurality of passages parallel to the main axis of the support, formed in the internal part of the support, a membrane of permeability Kand of mean thickness tcovering the internal surface of the passages; the external hydraulic diameter of the structure satisfying the relationship &#xd8;=&#x3b1;&#xd7;[A+B&#xd7;log(K&#xd7;t/K)]; in which &#x3b1; is a coefficient between 0.85 and 1.15, and A=&#x2212;21570&#xd7;ent&#x2212;18.6&#xd7;D+19.0&#xd7;e&#x2212;2.5&#xd7;e+0.1244 B=&#x2212;11760&#xd7;D&#xd7;e+9.7&#xd7;e+3.1&#xd7;e+0.04517. Dis the mean hydraulic diameter of the passages, eis the minimum thickness of the internal walls between the passages, eis the minimum thickness of the peripheral wall of the filter.

Thermal storage unit including: a receptacle including orifices allowing a heat-transfer fluid to be introduced into and extracted, and a stack of bricks, arranged in the receptacle in superposed strata, each stratum having lower and upper large faces and defining a plurality of ducts opening via lower and upper openings, the stack including a pair of strata of a lower and upper stratum, the upper and lower large faces of the lower and upper stratum being separated to define a passage, placing an upper opening of a lower duct of the lower stratum in fluidic communication with at least one lower opening, entirely offset with respect to the upper opening, of at least one upper duct of the upper stratum, the lower large face of the upper stratum closing off, at least partially, the upper opening, when the upper opening is observed, along its axis, from the lower duct.
