A device for cutting a plate or panel of porous construction material includes a movement structure that moves the plate or panel and includes at least one conveyor, and which is able to move in a direction (X). The device also includes a wire to cut the plate or panel and a structure for passing the wire in a direction (Y) perpendicular to the direction (X) of travel of the plate or panel. The device for cutting allows a cut to be made that greatly limits the waste and dust generated.

The disclosure is directed to a cutting process involving: (a) creating a starter crack using a scribe wheel, (b) application of laser or electrothermal heating, and (c) subsequent cooling from a gas or an aerosol jet, as the laser beam and cooling jet move along the desired cutting line. The cutting process can be implemented for cutting a glass panel or other substrate into a plurality of smaller panels. The starter crack may be created on any of the smaller panels within about 10 mm to about 20 mm from the corner of the smaller panel.

A solar roofing panel includes at least one photovoltaic device, including a front structure and a rear structure, and at least one solar collector capable of delivering hot water, including a front structure and a rear structure. The respective front structures of the photovoltaic device and of the solar collector include glass substrates forming a cover that has an upper face, to face an external environment, and an opposed inner face, the respective rear structures of the photovoltaic device and of the solar collector being placed beneath the cover, facing the inner face. The glass substrates have no metal frames and are joined together, or are separated by other transition glass substrates, so as to form a uniform unitary glass cover.

Solar roofing assembly

A tool holder device supporting at least one tool configured to collaborate with at least one substrate positioned on edge. The tool holder device makes the tool move translationally and rotationally relative to the substrate, it being possible for the substrate to be moved translationally relative to the tool as the tool is operating. Collaboration between the tool and the substrate occurs with or without contact relative to the edge face of the substrate.

Tool-holder device for cooperating with glass

A process for scanning a surface of a substrate, which process takes at least one reflected image of at least one test pattern on the surface and extracts by digital processing local phases in two directions. Variations in local slopes are calculated by digital processing from the local phases to deduce therefrom variations in curvature or variations in altitude of the surface.

An insulating glazing unit including at least two glass sheets spaced apart by a gas-filled cavity, an insert that serves to keep the two glass sheets apart and that has an internal face facing the gas-filled cavity and an opposed external face, and a sealing with respect to the inside of the glazing unit. The insert includes a substantially flat strip that surrounds a first part of the perimeter of the glazing unit, being pressed by its internal face against the edges of the glass sheets and kept fastened by a fastener, and another strip that surrounds a second part of the perimeter of the glazing unit.

A device for cooling bent glass sheets running along a roller conveyor. Blowing boxes are inserted between the rollers and have a surface opposite the glass sheet at a distance of less than 30 mm and preferably less than 10 mm. The surface is perforated with several holes through which air is discharged in the direction of the glass sheets.

A process and a device for duplicate molding on at least one part of a glazing, placed in a mold, particularly a monolithic or laminated glazing, of glass and/or of transparent plastic, by injection of plastic has at least two stations: a main station for the pressurization of a first mold, the injection of a plastic and the release of the molding pressure of the mold. Additional operations are being performed on a second mold at an auxiliary station. Transfers of the molds from the auxiliary station to the main station and vice versa are provided.

In a process and to an apparatus for bending a glass sheet heated to the bending temperature in a horizontal furnace, through which it is passed by a motor roller conveyor, which passes it into a bending cell where it is kept at an ambient temperature substantially identical to the bending temperature, the glass sheet is immobilized in the bending cell in an upper bending mold perpendicular to an annular countermold surrounding an element for supporting the central part of the glass sheet in the bending cell. The annular countermold is raised in order to press the glass sheet against the upper bending mold.

A device for supporting and transferring, in a shaping station (2), at least the central part of glass sheets which have been heated to their shaping temperature. The device includes a pressurized box (21) generating an air cushion. The box has a plurality of individual compartments (53), transverse with respect to the axis of travel of the glass sheets (28), each of the compartments (53) having a width measured parallel to said axis which is small by comparison with the 'height' of the glass sheets and, being provided with gas having at least two pressure distribution levels.

The invention is in a pneumatic powder ejector comprising a suction stage and an injection stage. The suction stage includes a suction chamber (16), a venturi (14) communicating a primary gas to the suction chamber and a lateral suction input (18) offset in relation to the downstream and of the venturi. The injection stage includes a nozzle (22), an injection chamber (36) and a diffuser (38). The stages are located within and coaxially of the body of a tubular ejector. The nozzle includes a path for powder and primary gas between the suction chamber and diffuser, and is formed to provide a flow path of reduced dimension to communicate a secondary or entrainment gas between the diffuser and injection station.

Device for metering pulverulent materials

A method and apparatus are described for coating a substrate such as glass with a powder such as a compound that can be decomposed by heat. The method comprises the steps of forming a sheet of powder suspended in a gas moving toward the substrate to be coated, homogenizing the mixture of powder and gas by creating turbulences in it, and accelerating the sheet in the direction of the substrate with flowing gas having greater velocity than that of the sheet. This method and the apparatus which implements it are particularly useful in the manufacture of glass coated with a film such as metal oxide.
