A spray nozzle device (100) comprises a connector (120), an inlet valve (130), and a spray nozzle (140). The connector (12) allows the device to be connected to a container (200) containing a fluid (201). The inlet valve (130) can be removably attached to a pump or a source of pressurised gas (300) to allow the interior of a said container (200) to be pressurised. The spray nozzle (140) is constructed and arranged so that, when the device (100)is connected to a container (200), the interior of which has been pressurised via the inlet valve (130), operation of the spray nozzle (140) causes fluid to be sprayed from the container (200) via the

A spray tank backpack apparatus for carrying spray tanks during use includes a frame having a frame left side, a frame right side, a frame top side, and a plurality of frame braces extending between the frame left side and the frame right side. A tank shelf is coupled to the frame and includes a shelf perimeter and a plurality of shelf braces. The shelf perimeter is coupled adjacent a bottom end of each of the frame left side and the frame right side. The plurality of shelf braces supports an industrial pressurized tank. A pair of hose brackets is coupled to the frame and is configured to receive a hose of the industrial pressurized tank. A pair of shoulder straps is coupled to the frame to be worn like a backpack.

A temporary radiotherapy facility for use during renovation, upgrading, and/or modernization of an existing facility. The radiotherapy facility includes a central vault room containing a radiation emitting device and a platform for holding a quantity of radiation shielding material above the central vault room. The platform is supported by shear walls that are disposed outside the sidewalls of the central vault room such that the radiation shielding material is supported and suspended above the central vault room without being in contact with or bearing upon the central vault room or affecting the height or level of the central vault room.

The Lawn Fast Spray Bottle has an Air valve that allows the user to put air into the sprayer by using an air compressor. The added air value is located at top side (shoulder) of the bottle.

A system and method for mixing and dispensing one or more pesticides includes a plurality of pesticide containers (5) for containing pesticide and at least one dosing device (7) associated with the pesticides containers and adapted to dose pesticide from the pesticide containers. A mixing device (9) receives pesticide from the dosing device and mixes the pesticide to form at least one of a pesticide solution and a pesticide mixture. A computer device (21) includes a processor and is adapted to receive an input from a user and based on that input operate the dosing device to dose a quantity of pesticide from one or more of the pesticide containers.

Fluid delivery systems, methods and apparatus to dispense a dose of fluid on an animal, which may be particularly used for behavior modification of the animal, are disclosed. A system may particularly comprise an apparatus wearable by the animal. The apparatus is suitable for storing a fluid contained therein, and dispensing a dose of fluid on the animal, particularly to spur or otherwise induce behavior modification of the animal, particularly in response to training stimuli during a training scenario.

A handheld, non-lethal deterrent spraying device comprising a housing structure configured to have a grip portion and a top portion, the grip portion and top portion being aligned to give the housing structure a pistol-grip orientation; a reservoir within the grip portion of the housing structure for containing a non-lethal deterrent; a nozzle recessed in a notch on the distal end of the top portion of the housing structure; a channel that connects the reservoir to the nozzle; an actuator that is accessible by a user and is manipulated by the user to engage a depressing member that causes the reservoir to discharge the reservoir's contents through the channel and out the nozzle; a cover member over the actuator, said cover member being attached to the housing structure, and being pivotable between a locked position which covers the actuator and an active position; and a specialized holster designed to hold the device and include a lockable hood to prevent undesired retrieval of the device.

A dual chamber backpack sprayer system includes first, second and third tanks, and a pump unit. The first tank includes a first tank housing defining an open internal volume configured to hold a diluent therein. The second tank is dimensioned to be received within the internal volume of the first tank and is configured to hold a pressurized fluid therein. The third tank includes a third tank housing configured to hold a liquid concentrate therein. The pump unit is fluidly coupled to the first tank, the second tank and the third tank. The pump unit is configured to receive the diluent from the first tank and the liquid concentrate from the third tank to produce a mixed fluid. The mixed fluid is delivered to the second tank as the pressurized fluid.

A drain gun includes a handle and a trigger. The handle includes a channel and a plurality of inlets. The inlets feed the channel. The trigger causes a staged release of a plurality of fluids from a plurality of cartridges to the channel via the inlets when the cartridges are stored in the handle and feeding the inlets.
