The invention relates to non-ferrous metallurgy and the electrolytic production of aluminium, and can be used for lining the cathode assembly of an electrolytic cell. The present method consists in laying materials while simultaneously distributing same over the surface of a base and levelling them at a height measured from the plane of the top edge of the shell of the cathode assembly of the electrolytic cell by gradually moving a device for installing unformed lining materials along the longitudinal axis of the cathode of the aluminium electrolytic cell. Said device is configured in the form of a bridge equipped with a mechanical drive for movement. The bridge has guides on which a frame is mounted for vertical movement, said frame having cassettes provided with gates with a mechanical drive. The technical result is reduced labour costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

Disclosed are methods and systems for continuously coating food pieces. The methods include a steps of directing and uncoated food stream through an enrober to apply a first coating to at least a portion of a surface of each food piece to form a coated stream and continuously redirecting a portion of the coated stream back through the enrober along with the stream of uncoated food pieces to apply at least one additional coating to the portion of the coated stream.

An apparatus for depositing organic layers on a substrate includes a gas-mixing device with one or more inlets, each for supplying a gas flow consisting of previously vaporized organic molecules that are conveyed by a carrier gas and have a molar mass greater than 300 g/mol or 400 g/mol, gas diversion elements which homogeneously mix the organic molecules in the carrier gas, and an outlet from which a homogeneous gas mixture discharges. The apparatus also comprises a conveying pipe which is connected to the outlet, and a gas inlet element that has a gas distribution volume, into which the conveying pipe leads and which has a gas outlet face that has gas outlet openings and faces a substrate holder for receiving the substrate. Furthermore, layers are deposited on the substrate using such an apparatus. The lateral homogeneity of the deposited layers is improved by one of several techniques.

A powder spreading apparatus includes a hopper having a first end, a second end opposite from the first end, a front wall, a rear wall opposite from the front wall, and a floor. The front wall, the rear wall, the first end, the second end, and the floor define an interior. An impeller is disposed within the interior of the hopper. The impeller includes a plurality of circumferentially spaced flutes and is configured to rotate about an impeller axis that extends from the first end of the hopper to the second end of the hopper to deposit powder onto a print area. A spreader rod is coupled to the hopper and extends along a spreader rod axis parallel to the impeller axis. The spreader rod is configured to rotate about the spreader rod axis to smooth the powder as it is deposited onto the print area.

A dry product spreader is provided that includes a bin that includes a bin discharge opening. The dry product spreader further includes a conveyor located at the bottom of the bin. The conveyor is capable of discharging dry product material from the bin through the bin discharge opening. The dry product spreader further includes a spinner assembly for spreading the dry product material and positioned to receive the dry product material from the bin discharge opening. The dry product spreader further includes a material conveyance system to displace dry product material received through the bin discharge opening before the dry product material reaches the spinner assembly. The dry product spreader further includes a distribution manifold configured to receive dry product material displaced by the material conveyance system. The distribution manifold is configured to return dry product material displaced by the material conveyance system to be spread by the spinner assembly.

A system for forming a particle layer on a substrate may include at least one sprayer and at least two masks configured to selectively mask a substrate in a first region and second region of the substrate. The at least one sprayer may be configured to spray particles at the substrate, where the at least two masks maintain the first region and second region substantially free of the deposited material. A heater may be employed to heat the substrate as the particles are sprayed by the at least one sprayer onto the substrate.
