The disclosure relates to a substrate coating apparatus that comprises a source of a washcoat; a washcoat showerhead for discharging the washcoat towards an upper surface of a substrate; a conduit fluidly connecting the source of the washcoat to the washcoat showerhead for supplying washcoat to the washcoat showerhead; a headset for engaging the substrate to locate the upper surface of the substrate below the washcoat showerhead; and a vacuum generator for drawing the washcoat discharged from the washcoat showerhead through the substrate. The headset comprises a partition comprising a plurality of holes, the partition being located in between the washcoat showerhead and the upper surface of the substrate when the substrate is engaged in the headset so as to maintain a first gap between a lower face of the partition and the upper surface of the substrate.

This intermittent coating device is provided with a die which applies paint to a workpiece, and a first intermittent valve and a second intermittent valve which can switch between a first state in which paint is provided to the die and a second state in which provision of paint is stopped. The first intermittent valve and the second intermittent valve have mutually different timing for switching between the first state and the second state.

A robot end effector for dispensing an extrudable substance comprises a chassis, cartridge bays, attached to the chassis and each shaped to receive a corresponding one of two-part cartridges, and a manifold, comprising a manifold outlet, manifold inlets, and a valve inlet. When the two-part cartridges are received by the cartridge bays, the manifold inlets are in fluidic communication with corresponding ones of the two-part cartridges via static mixers, attached to cartridge outlets of the two-part cartridges. The robot end effector additionally comprises a head assembly, comprising pairs of fittings, configured to selectively supply compressed air from a pressure source to the two-part cartridges when the two-part cartridges are received by the cartridge bays, so that contents of the two-part cartridges are concurrently extruded through the cartridge outlets.

The present invention provides a nozzle (201), which comprises a nozzle passage (512) and a fluid passage (511), wherein the nozzle passage has an airflow inlet (515) and an airflow outlet (516). The fluid passage has a fluid passage inlet (518) and a fluid passage outlet (514), wherein the fluid passage inlet communicates with a fluid source so that a fluid can enter the fluid passage, and the fluid passage outlet communicates with the nozzle passage so that the fluid can enter the nozzle passage, and the airflow exerted from the airflow inlet can press the fluid in the nozzle passage out of the airflow outlet. The nozzle provided by the present application can distribute a small volume of a viscous fluid and is not apt to get blocked.

An application device for a viscous adhesive comprising a base body having a first inlet for a viscous adhesive; and a nozzle body which is rotatable about an axis with respect to the base body and which surrounds a portion of the base body radially on the outside with respect to the axis, wherein, via the interaction of a first dynamic seal with a separating agent chamber, in which a separating agent is stored, the introduction of humidity into the adhesive before it exits the nozzle opening is effectively prevented.

The invention relates to a dosing system (1) for a dosing material having a nozzle (40), a feed channel (44) for dosing material, a discharge element (31), an actuator unit (10) that is coupled to the discharge element (31) and/or the nozzle (40) and has a piezo actuator (60), and a cooling device (2). The cooling device (2) comprises a supply device (21, 24, 26) for feeding a precooled cooling medium into a housing (11) of the dosing system (1). The cooling device (2) is configured for direct cooling of at least one subregion of the piezo actuator (60) and/or at least one subregion of a movement mechanism (14) coupled to the piezo actuator (60) by means of the precooled cooling medium.

A fluid dispenser for dispensing small doses of fluid includes a dispenser housing, a diaphragm assembly, a displacement chamber, and a dispensing luer. The dispenser housing has a first end for receiving the fluid and a second end for dispensing the fluid. The dispenser housing defines a fluid flow path from a receiving chamber adjacent the first end to a dispensing chamber adjacent the second end. The diaphragm assembly includes a first diaphragm within the receiving chamber and a second diaphragm within the dispensing chamber wherein the first diaphragm is operably connected to the second diaphragm. The diaphragm assembly is movable between a first position wherein the first diaphragm moves the fluid from the receiving chamber to the dispensing chamber along the fluid flow path and a second position wherein the second diaphragm moves the fluid from the dispensing chamber to the displacement chamber.

A device and method for dispensing a flowable medium has a housing with an interior space and a rod mounted in the housing that is movable between a first end position and a second end position and passes through a diaphragm mounted in a sealed manner in the housing radially on the outside and in the rod radially on the inside. The diaphragm divides the interior space into a first cavity and a second cavity separated from the first cavity in a fluid tight manner. The flowable medium can flow through at least one channel that opens into the first cavity, and is dispensed through a dispensing opening. A sealing section of the rod closes the dispensing opening in the first end position and is at a distance from the dispensing opening in the second end position. A pressure medium acts on the diaphragm in the second cavity.

A method and apparatus for forming a sealant coating on a fastener are provided. The apparatus comprises a light generator, a light housing, and a forming cup. The light generator is configured to generate light having a number of characteristics that cures the sealant coating on the fastener. The light housing surrounds the light generator. The forming cup is removably connected to the light housing. The forming cup has an internal cavity with an inner mold line complementary to an outer mold line for the sealant coating.

A method is provided for coating a surface of a material with a film of porous coordination polymer. A first substrate having a first surface to be coated is positioned in a processing chamber such that the first surface is placed in an opposing relationship to a second surface. The second surface may be provided by a wall of the processing chamber, or in some cases the second surface may be provided by a second substrate to be coated. The first substrate is held such that a gap exists between the first and second surfaces, and the gap is filled with at least one reaction mixture comprising reagents sufficient to form the crystalline film on at least the first surface. A thin gap (e.g., less than 2 mm) between the first and second surfaces is effective for producing a high quality film having a thickness less than 100 μm. Confining the volume of the reaction mixture to a thin layer adjacent the substrate surface significantly reduces problems with sedimentation and concentration control. The size, shape, or average thickness of the gap may be adjusted during formation of the film in response to feedback from at least one film growth monitor.
