An apparatus (100) for dispensing a flowable material (308) is disclosed. The apparatus (100) comprises a rotary actuator (120), a reservoir (140), containing a hydraulic fluid (155), a piston (145), movable inside the reservoir (140), a linear actuator (130), coupled to the piston (145), a gear train (125), coupling the rotary actuator (120) with the linear actuator (130), and a flowable-material dispenser (160), hydraulically coupled with the reservoir (140).

A sealant discharging nozzle includes a nozzle body, a flat surface, a nozzle positioning portion, and a locating pin. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The nozzle positioning portion includes a pair of tapered surfaces disposed on both sides of the flat surface in a width direction of the flat surface. The locating pin is formed between the pair of tapered surfaces.

A coating apparatus includes an open/close valve having a motor that allows control of opening operation and closing operation in accordance with electric signals applied from a controller. The coating apparatus further includes a suck back valve having a motor that allows control of a volume variation in a flow path for suck back that is in communication with an upstream side and a downstream side of a pipe in accordance with electric signals from the controller. The controller allows control of start of the closing operation of the open/close valve and start of suction operation of the suck back valve through application of the electric signals to the respective motors. This achieves simple adjustment of liquid cut-off.

An apparatus for coating a donor surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises an application device to apply to the donor surface a fluid stream within which the particles are suspended, a housing surrounds the application device forming an interior plenum for confining the fluid stream, the housing prevents egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum excess fluid and particles. In operation, the suction source extracts substantially all particles that are not in direct contact with the donor surface, leaving substantially a single particle layer adhering to the donor surface upon exiting the apparatus.

A metering device is disclosed for regulating the depth of flowable product coating a surface movable relative to the metering device by directing an air curtain towards the surface. The metering device comprises a body (10) having an interior chamber (12), an inlet for connecting the chamber to a source of gas under super-ambient pressure; and an opening (16) communicating with the chamber and having a mouth through which gas is discharged from the chamber towards the surface to form the air curtain. A porous or reticulated membrane (18) is secured to, or formed integrally with, the body of the device to lie in the path of the gas discharged through the mouth of the opening.

A device applies a coating to a surface of an turbomachine annular casing, wherein the casing has an abradable layer obtained by polymerising a resin. The device includes first support means and, optionally, second automated means movable relative to the first support means. The automated means includes means for depositing said resin on the surface of the casing. The automated means further includes means for spreading the resin on the surface of the casing, and means for unwinding a plastic film that is intended to be interposed between said spreading means and the resin.

A die head apparatus is provided with a front blade, a rear blade, a center blade, and an internal impurity removal space. The front blade and the center blade are configured to form a pool of a slurry. The internal impurity removal space is positioned between the center blade and the rear blade. A distance separating the rear blade and the substrate is set to be smaller than the distance separating the center blade and the substrate.

This disclosure relates to non-ferrous metallurgy and electrolytic production of Aluminium for lining a cathode assembly of an electrolytic cell. The present method includes 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 a 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 labor costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer of fibers and adhesive providing dimensional stability for the entire floor covering. The fibers and adhesive are mixed and then moved by an applicator towards the stitches. A slip path is formed to improve the movement of the fibers and adhesive. A releasable adhesive or gecko-like cover system is provided which also provides additional strength and stability and a releasable attachment of the universal floor covering to a supporting surface.

Systems, methods, and apparatus are disclosed for shaping sealant applied to a fastener. Methods include pressing, using an end effector of a robotic arm, a dabbing tool against the sealant, the sealant sealing a surface of the fastener along a surface of an assembly, the pressing of the dabbing tool shaping an exterior surface of the sealant. Methods also include releasing an amount of solvent from the dabbing tool in response to the pressing, the amount of solvent reducing adhesion between the dabbing tool and the sealant, the amount of solvent being released, at least in part, from a porous member included in the dabbing tool. Methods further include disengaging the dabbing tool from the sealant after the shaping of the exterior surface of the sealant.
