A modular apparatus for coating glass articles with a chemical compound includes a coating hood section (10a) including a series of interconnected walls (12) defining an interior chamber (18, 20a, 20b) having an inlet (32) and an outlet (44), a blower (24) positioned at least partially in the interior chamber (18, 20a, 20b) to carry air from the inlet (32) towards the outlet (44); and a connector (50) for connecting the coating hood section (10a) to an identical coating hood section (10b). The connector (50) for connecting being defined on at least one of the interconnected walls (12) of the coating hood section (10a).

Machine for applying sealing material to a metal element comprises at least one electromagnetic mandrel provided with a main body to house at least one electromagnet and a support to hold the metal element in position on a work surface following the excitation of the electromagnet; the main body is connected to drive means configured to make the support rotate on the work surface; the delivery device of the sealing material is positioned at least in proximity to the periphery of the metal element and is able to deliver sealing material when the metal element is held in position and made to rotate on the work surface by means of the support of the electromagnetic mandrel.

A decontamination device configured to provide, on a short time scale, uniform decontamination of target articles without using expensive electron accelerators and to treat articles to be decontaminated in large quantities.

The device includes a device body composed of a decontamination region and an aeration region, a conveyance means for conveying an article, a mist supply means, a mist control means, and an aeration means. The mist supply means converts a decontamination agent into a decontamination agent mist and supplies the same to the inside of the decontamination region. The mist control means includes vibration boards adjacent to internal wall surfaces of the decontamination region, and these boards are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The decontamination agent mist supplied to the inside of the decontamination region is pressed by acoustic radiation to concentrate such mist on external surfaces of the article conveyed inside the decontamination region.

A system may include a support surface for supporting a substrate, a plurality of first passages arranged to distribute flows of a first gas to establish a gas bearing to float the substrate above the support surface, and a plurality of second passages arranged to distribute flows of a second gas to convey the substrate along the support surface. A method may include floating a substrate above a support surface of a substrate support apparatus via a gas bearing; and while floating the substrate, conveying the substrate along the support surface by flowing gas toward a surface of the substrate and in a nonperpendicular direction relative to the surface of the substrate.

A linear transport system comprising a linear motor with at least a motor module and at least a conveyor driven by the linear motor along a path of motion is described. The motor module thereby comprises a stator magnetically interacting with a magnet device of the conveyor and having a plurality of stator teeth arranged side by side along the path of motion and a plurality of electric coils each wound around a stator tooth. The linear transport system further comprises a fluid system comprising at least a fluid channel passing through a stator tooth of the stator of the motor module.

A method for improving the performance of hydraulic fracturing processes in oil production fields wherein modifiable coated proppants used in the fracturing fluid are produced on a well-site. Various types of coated proppants may be produced based on real-time, down-hole information obtained and utilized at the well-site.

Provided is an assembly including a dump body configured to be supported by a frame to be moved relative to the frame between a dump position and a load position. The dump body includes first and second sidewalls, a front wall, a floor having a first opening, a tailgate, and an apron below the tailgate, the apron having a second opening substantially perpendicular to the first opening. The assembly also includes an endless conveyor configured to direct material to the second opening and being removably attached to the dump body below the floor such that material is prevented from exiting the dump body through the first opening.

A modular apparatus for coating glass articles with a chemical compound includes a coating hood section (10a) including a series of interconnected walls (12) defining an interior chamber (18, 20a, 20b) having an inlet (32) and an outlet (44), a blower (24) positioned at least partially in the interior chamber (18, 20a, 20b) to carry air from the inlet (32) towards the outlet (44); and a connector (50) for connecting the coating hood section (10a) to an identical coating hood section (10b). The connector (50) for connecting being defined on at least one of the interconnected walls (12) of the coating hood section (10a).
