The invention relates to a plasma coating device (10) and a method for homogenous coating of a substrate (12). It comprises a particle reservoir (14), a dosing device (16) for dosing the particles (15) contained in the particle reservoir (14), a processing chamber (20) and a transport line (18) to convey particles (15) into the processing chamber (20). The processing chamber pressure (P1) in the processing chamber (20) is lower than the particle reservoir pressure (P2) in the particle reservoir (14).

The invention relates to a device for conveying a fine-particle medium, in particular a granulate, including a flexible receptacle for receiving the medium, a receiving fixture for fastening of the receptacle in the region of an upper end facing away from a base of the receptacle, and a suction apparatus, inserted from above into the receptacle, for sucking the medium out of the receptacle. The device further includes outside the receptacle, in its base region or its lateral region, an apparatus for acting on the receptacle for the purpose of its deformation. The device ensures that feed interruptions during the conveyance of the fine-particle medium are avoided so that the medium is kept in a conveyable state, whereby an undisturbed automated feed of the medium is secured.

A Venturi pump used for sucking powder from a supply, diluting the same, then feeding it to a gun via a conveyor pipe. The pump comprises an outer body, at least one powder suction duct, at least two air connections, of which a first air connection is capable of supplying an injector to create a vacuum inside the suction duct and a second air connection is capable of supplying a dilution air circuit separate from the powder flow. The pump including at least one powder outlet nozzle centered on an axis of diffusion, the inlet of which is located downstream from the first air connection and the suction duct. At least one protection barrier contains a non-return valve disposed inside the dilution air circuit and at least one outlet tip of the dilution circuit disposed around the nozzle and also connected to the conveyor pipe.

The invention relates to a screen insert (70) for a powder container (24) of a powder supplying device, the screen insert (70) having a screen unit (71) for screening coating powder and an ultrasonic transducer (72) for generating ultrasonic vibrations. The screen unit (71) is connected to the ultrasonic transducer (72) in such a way that the ultrasonic vibrations generated by the ultrasonic transducer (72) can be transferred to the screen unit (71). To allow a particularly compact construction of the screen insert (70) to be achieved, according to the invention a screen carrier (73) which can be placed onto the powder container (24) is provided, for holding the ultrasonic transducer (72), with the screen unit (71) connected thereto, in such a way that the screen unit (71) is arranged below the screen carrier (73), so that the screen unit (71) is inside a powder chamber (22), formed by the powder container (24), when the screen carrier (73) has been placed onto the powder container (24).

A pump, supplying powder for a variety of uses, has an outer body with an internal cavity; a compartment in the body has a volume which is variable on command by means of a motor drive, from a first condition, in which it fills with powder through openings that are in communication with a container that contains the powder to be dispensed, to a second condition, in which it is in contact with the initial part of a dispensing duct; a valve intercepts the duct and a first connector supplies compressed air to the compartment; a second connector controls the valve, and a third connector supplies air for the conveyance of the powder.

A powder discharge device includes a powder thin flow pump for delivering powder, particularly coating powder, from a powder reservoir to a powder spray device, with a control device being integrated in the powder discharge device, which control device is designed to adjust at least one parameter, which is characterizing in relation to a spray coating process performed with the powder spray device and/or in relation to a powder delivery performed with the powder thin flow pump, the control device forming a structural unit with the powder thin flow pump.

Apparatus and methods are provided for the manufacture of filtration articles. The apparatus and methods include a separate first chamber for dispersion of the inorganic particles and a larger second chamber for deposition of the inorganic particles on a single honeycomb body or multiple honeycomb bodies.

A venturi cartridge regulating device for an air-particle dispensing system is provided, which is designed to be pre-assembled and installed in a chamber capable of atmospheric pressurization to regulate the required proportions of air and particle in a mixture formed upon activation by a propellant source and to direct a stream of a particle-gas mixture out of the chamber toward a targeted surface. The apparatus includes a chamber comprising a first plurality of inlet holes and a second plurality of inlet holes; and a conduit arranged at least partially within the chamber having a first opening arranged in the chamber. The first plurality of inlet holes is configured to intake a first substance, the second plurality of inlet holes is configured to intake a second substance, and a mixture of the first and second substances is created and mixture enters the conduit through the first opening.

The present invention provides a method for quantitatively and stably supplying fine powder and a system for implementing the method. In this invention, in a state in which at least part of the ultrasonic vibration gushing portion is in contact with the fine powder surface of the surface layer of the fine powder stored in the fine powder storage container, the powder inlet of the feed nozzle takes in the fine powder rising from the fine powder surface onto the ultrasonic vibration gushing portion through the passage region of the ultrasonic vibration gushing portion, together with the carrier gas, by ultrasonically vibrating at least part of the ultrasonic vibration gutting portion.

The present invention relates to a Venturi powder gun comprising a body, an injector of drive gas and an ejector of a mixture comprising the powder product, mounted in the body. The body defines a duct for circulating the mixture, upstream of the ejector. The injector and the ejector are straight and extend respectively along an injector axis and an ejector axis, which coincide when the powder pump is in the assembled configuration. Means for indexing the position of the ejector within the pump body, in rotation about the ejector axis, make it possible to align an inlet of a suction chamber with the mixture circulation duct defined by the pump body.
