A method is provided of applying a coating material to a concave surface of an article that has a rim around the concave surface, and a cavity between the concave surface and the rim. The method includes discharging coating material in a liquid form into the cavity, extracting a first amount of the discharged liquid coating material from the cavity, thereby leaving a residual amount of the liquid coating on the concave surface within the cavity, and maintaining the article in conditions appropriate to allow the residual amount of liquid coating material to cure on the concave surface.

A substrate processing apparatus includes a chamber, a substrate holding part, a substrate rotating mechanism, and a processing liquid supply part. The chamber includes a chamber body and a chamber cover, and the chamber cover is moved up and down by a chamber opening and closing mechanism. A top plate is attached to the chamber cover. While the chamber cover is in contact with the chamber body, a sealed space is formed and processing is performed. When the chamber cover is moved up, an annular opening is formed between the chamber cover and the chamber body. A cup part is positioned outside the annular opening. A processing liquid spattering from a substrate is received by the cup part.

The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.

An applicator system includes a delivery apparatus and a dispenser assembly. The delivery apparatus includes a carrier configured to support first and second containers containing first and second liquids, the first and second containers having first and second outlets. The dispenser assembly includes a frame, a first distribution manifold removably connected to the frame, and a plurality of nozzles. The first distribution manifold includes an inlet and a plurality of outlets in fluid communication with the inlet. Each of the plurality of nozzles is removably fluidly coupled to a corresponding outlet of the first distribution manifold. The applicator system further includes a first hose, wherein one end of the first hose is removably fluidly coupleable to the inlet of the first distribution manifold and another end of the first hose is removably fluidly coupleable to at least one of the first outlet and the second outlet.

A paint circulation system includes a paint reservoir, a pressure transducer, a servo motor driven pump, an electronic servo drive and controller, one or more paint applicators in a spray booth and an isolation valve. The pressure transducer provides a signal to the controller indicating the current pressure in the system. The servo pump is controlled by the controller and servo drive, draws paint from the reservoir and maintains the desired pressure in the system. The isolation valve is downstream from the applicators and is closed when paint is requested by the applicators. When paint is flowing to the applicators, the servo drive adjusts pump speed to maintain the desired system pressure as sensed by the pressure transducer. When paint is not requested, the isolation valve is open and the servo pump motor operates to provide a minimum flow rate to circulate paint from, and return it to, the reservoir.

An extrusion coating apparatus includes a housing having an inner chamber, a housing wall of the housing having a feed port and a coating outlet both communicated with the inner chamber, the coating outlet being in a slit shape; and further includes a porous structure disposed in the inner chamber and located on a material flow path between the feed port and the coating outlet, so that at least a portion of a material passes through the porous structure.

A remote metering station for pumping a flow of adhesive to a dispensing module is disclosed. The remote metering station includes a manifold having a front surface, a back surface opposite to the front surface, a first side surface, a second side surface opposite the first side surface, a top surface, and a bottom surface opposite to said top surface. The remote metering station also includes a modular pump assembly removably mounted to the manifold, where the modular pump assembly includes a bottom surface, an outlet on the bottom surface, the outlet being in fluid communication with the manifold, and an inlet for receiving the adhesive. The modular pump assembly further includes a gear assembly and a drive motor coupled to the gear assembly. The gear assembly is operable for pumping the adhesive from the inlet to the outlet.

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

An applicator for dispensing adhesive is disclosed. The applicator includes a manifold, at least one dispensing module coupled to the manifold, a supply channel configured to contain at least a portion of the adhesive, a recirculation channel configured to contain at least a portion of the adhesive, and a recirculation pump assembly connected to the manifold. The recirculation pump assembly includes an inlet in fluid communication with the recirculation channel, an outlet in fluid communication with the supply channel, a gear assembly, and a drive motor coupled to the gear assembly and operable to pump the adhesive, where the drive motor is configured to operate at an adjustable number of revolutions per minute (RPM). The recirculation pump assembly can be configured to move at least a portion of the adhesive from the recirculation channel to the supply channel, such that a first pressure of the adhesive in the recirculation channel is substantially equal to a second pressure of the adhesive in the supply channel.
