A vortex ring generation device is configured to release an airflow in a form of a vortex ring from a release port. The vortex ring generation device includes a plurality of gas chamber units, an actuator, and a communication path. Each gas chamber unit has an air chamber that communicates with the release port. Each gas chamber units includes a fixing member forming the air chamber, and a movable member moving to push air out of the air chamber. The movable members of all of the gas chamber units are coupled together to form one movable body. The actuator is connected to an end portion of the movable body and is configured to drive the movable body. The communication path allows the air chambers of the plurality of gas chamber units to communicate with each other.

A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.

Described are riser assemblies suitable for use with fluid dispensers. The assemblies include a container partially circumscribing a reservoir configured to contain a pressurized fluid, the container having a fluid inlet and a fluid outlet disposed therethrough. The assemblies may further include a signal processor situateable outside the container that is configured to receive a signal. The signal processor may be operatively connectable to a control valve that is operatively connectable to the fluid dispenser. The control valve may be configured to selectively control expulsion of the fluid through the fluid dispenser in response to the signal received by the signal processor. Embodiments of the riser assemblies include a utility conduit disposed at least partially within the reservoir and configured to enable secondary use of a resource from within the riser assembly and/or to accommodate transport and securing of the riser assemblies for use.

A thermal spray cabin comprising a table to hold a part to be coated and a robot with a robot body and an arm, a spray gun mounted on the arm of the robot, a ventilation system comprising an air inlet and a suction hood designed to create a gas flow with a main stream from the air inlet to the suction hood thereby passing the table in an operating state of the thermal spray cabin. The air inlet, the table, the robot and the suction hood are arranged in such a way, that the robot body is positioned outside the main stream of the gas flow in the operating state.

A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

A toilet tissue mister includes a cabinet with an open lower front section for receiving a user's hand bearing toilet tissue. A liquid-containing bottle is maintained within the cabinet above the open lower section. A spray head is positioned at a top portion of said open lower front section and a pump is interconnected between the bottle and the spray head. A control circuit is interconnected with an optical transducer switch maintained within said open lower front section and, upon sensing the presence of a user's hand, actuates the pump for a duration of time sufficient to coat the toilet tissue in the user's hand with a spray mist from the spray head.

A system is provided that includes a support structure and a nozzle. The support structure includes a cavity surface and an aperture. The cavity surface at least partially forms a boundary of a cavity. The aperture extends partially into the support structure from the cavity surface. The nozzle includes a mount, a neck and a head. The mount is seated within the aperture. The neck is connected to the mount and extends axially along a centerline away from the surface to the head. The head is configured to inject fluid out of the nozzle and into the cavity.

An aerosol dispensing apparatus having a focus straw storage chamber located internal to the aerosol spray container, such that the focus straw may be stored in a fully protected and safe environment away from external elements that may cause damage or result in the loss of the focus straw. The internal storage chamber is attached in sealed relation to the interior surface of the aerosol spray container, with an opening extending to the exterior of the container, thus providing an access to the internal storage chamber within which a focus straw may be inserted. A protective cover is provided for the internal storage chamber access opening to maintain a safe, clean storage environment for the focus straw and prevent inadvertent loss thereof when not in use.

A drywall texture dispensing system includes an air gun that may be fluidly coupled to an air source. A reservoir is provided and the reservoir may contain a fluid. The reservoir is removably coupled to the air gun such that the reservoir is in fluid communication with the air gun. The reservoir has a diameter that is less than approximately thirty cm. Thus, the reservoir facilitates the air gun to dispense the fluid in a restricted area. A lid is removably coupled to the reservoir.
