A clotting agent delivery system comprises a frame, a passageway extending along the frame, a discharge opening connected to the passageway, a clotting agent reservoir fluidly connected to the passageway to hold a clotting agent substance, a valve in the passageway to control flow of the substance through the passageway, and an actuator to allow propellent to flow into the passageway, wherein the valve and clotting agent reservoir cooperate to provide clotting agent substance to the discharge opening at constant pressure using the propellant. A method for delivering a clotting agent comprises inserting a delivery catheter into an anatomic area, coupling a clotting agent delivery system to the delivery catheter, the clotting agent delivery system having a reservoir of a clotting agent, operating a valve to release propellant for propelling the clotting agent, and conveying the propellant and the clotting agent to the delivery catheter at a constant pressure.

The invention relates to a dense-phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or similar device for spraying coating powder. The dense-phase powder pump has at least one powder conveying chamber, which is/can be fluidically connected to the first powder reservoir via a powder inlet, and to the second powder reservoir or to the powder spray-coating gun or similar device for spraying coating powder via a powder outlet. At least one powder inlet valve is provided at the powder inlet and at least one powder outlet valve is provided at the powder outlet. According to the invention, in order to make the dense-phase powder pump less prone to require maintenance during operation and, in particular, to constantly guarantee a continuous and uniform conveying of the powder, regardless of the type of powder, the at least one powder inlet valve and/or the at least one powder outlet valve has/have an effective flow cross-section in the respective open state, which corresponds to at least 35% of the effective flow cross-section of the at least one powder conveying chamber.

The invention relates to a distributor (10) for granular material, having a distributor head (14), which is designed to divide up an air-material main flow supplied through a main conveying line (12) to the distributor head (14) into a plurality of air-material individual flows, and at least one return device (16), which comprises a movable deflecting element (36), which is designed, in a delivery position, to supply an air-material individual flow flowing into an inflow region (26) of the return device (16) to a delivery region (28), connected to a delivery line (18), of the return device (16) and, in a shut-off position, to direct an air-material individual flow flowing into the inflow region (26) of the return device (16) via a return line (30) of the return device (16) to a return region (32), connected to the main conveying line (12), of the return device (16).

A method for manufacturing a pillar-shaped honeycomb structure filter including; attaching ceramic particles to a surface of the first cells by ejecting an aerosol including the ceramic particles toward the inlet side end surface from a direction perpendicular to the inlet side end surface while applying a suction force to the outlet side end surface to suck the ejected aerosol from the inlet side end surface, wherein the ejection of the aerosol is carried out using an aerosol generator including a drive gas flow path for flowing a pressurized drive gas, a supply port provided on the way of the drive gas flow path and capable of sucking the ceramic particles from an outer peripheral side of the drive gas flow path toward an inside of the drive gas flow path, and a nozzle attached to a tip of the drive gas flow path and capable of ejecting the aerosol.

Apparatus for forming a 3D object from powder, comprising: a) delivery means adapted to emit a flow of powder at sufficiently high velocity to enable it to form the 3D object; b) positioning means adapted adjust the position of the delivery means; and c) control means adapted to control: i) movement of the positioning means; and ii) the velocity of the flow of powder.

An extensible pesticide applicator is provided enabling application of both liquid and powdered insecticides to distal, out-of-reach areas. An extensible pole has a distal and a proximal end for manual wielding whereby a pair of nozzles is deployable proximal an out-of-reach habitat. Pressurization of ambient atmosphere into the extensible pole is enabled by a pump member and timed release of the pressurized ambient atmosphere to forcibly eject powdered and alternately liquid pesticide from the distal end is enabled by manual action effected to depress a trigger member. Direct application of pesticide is thereby enabled to distal and out-of-reach habitat without a user coming into proximity with the habitat or the pesticide released.

A selectively configurable spray gun may include a gun body comprising a selectable forward section and a rearward section. The rearward section may be connected with either of two or more selectable forward sections so as to selectively configure the spray gun to operate either with a dense phase powder supply configuration or a with dilute phase powder supply configuration. The rearward section may include a selectable powder flow path that is connectable at an inlet end to a source of dense phase powder and at an outlet end to a selectable spray nozzle in the selectable forward section that may optionally include a diffuser. An adapter may be used to connect the rearward section with a selectable spray nozzle or air cap. A manual spray gun embodiment is also presented. A selectively configurable spray gun for use with a dense phase powder supply may include a smaller diameter powder tube that extends through a larger diameter powder tube.

A particulate spray booth having a sealed particulate spray device booth wall opening is disclosed. The powder coating material spray system may include a booth comprising a ceiling, a floor, and side walls defining an interior of the booth, wherein the booth defines an opening from the interior of the booth to an exterior of the booth. The system may further include a powder spray device received through the opening, the powder spray device comprising a body and a nozzle through which powder coating material is sprayed into the interior of the booth, wherein the nozzle and at least part of the body are disposed in the interior of the booth. The system may further include a flexible boot element having a proximal end and a distal end opposite the proximal end, the proximal end attached to a periphery of the opening to form a first seal and the distal end attached to the at least part of the body of the powder spray device disposed in the interior of the booth to form a second seal.
