A bead flow sensor module includes a housing, a beam, and a sensor. The beam extends into a flow channel of the housing through which a flow of beads and compressed air flows. The sensor outputs a signal indicative of bead impacts on the beam. A system incorporating the bead flow sensor module includes a compressed air source, a bead hopper, and a bead dispenser. The compressed air source delivers a flow of compressed air to the bead hopper. A flow of beads carried by the compressed air discharges from the bead hopper along a flow pathway connecting the bead hopper to the bead dispenser. The bead flow sensor module positioned along the flow pathway outputs the signal from which a bead flow volume through the bead dispenser is determined.

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 thermal sprayer system includes an injector conduit in communication with an injector and a first valve for selectively directing a coating fluid through the injector conduit. A flush fluid conduit is in communication with the injector conduit for directing a flush fluid through the injector conduit. A pressurized air conduit is in communication with the injector conduit for directing a pressurized fluid through the injector conduit.

An injection device includes: an injection nozzle injecting an injection agent into a target container, and a vibration generating device vibrating the injection nozzle in a plurality of directions during injection of the injection agent.

A nozzle ejecting liquid and nozzle device ejecting a liquid upon mixing an abrasive into a liquid jet stream, obtains a converged jet stream. A nozzle includes: a main body; a buffer chamber in the body, whose central axis is an axis line being the liquid jet stream central line; a constrictor part ejecting the liquid, in a buffer chamber plane on a buffer chamber front side and whose central axis is the axis line; a disk plate inside the buffer chamber, facing the plane on the buffer chamber front side and whose central axis is the axis line; a supporting member supporting the disk plate within the buffer chamber; a supply opening in the body supplying the liquid; and an inflow channel along a direction different from the axis line extending direction, opened on a disk plate rear side and the buffer chamber and communicating with the opening.
