A thin film induction nebulizer is disclosed herein. The nebulizer has a gas capillary and a liquid capillary that are aligned in the same direction within a nebulizer housing and are substantially aligned with a main axis of the nebulizer housing. The nebulizer includes a liquid opening configured to allow liquid to exit the liquid capillary and a gas orifice configured to allow gas to exit the gas capillary. The liquid capillary opens into a chamber that is formed from a liquid channel having a roughened surface and a cover plate. The cover plate interfaces with the liquid channel to partially seal the chamber. The chamber includes an opening where the liquid opening opens into the chamber and also includes another opening proximal to the gas orifice. The end of the nebulizer housing that is proximal to the liquid opening and the gas orifice includes two angled exterior surfaces.

Disclosed is a monitoring system, and associated method, relating to the operation of a dairy plant, the system being adapted or able to monitor one or more of the following criteria: the mixing and/or dispensing of animal health products, the mixing and/or dispensing of teat treatments, the mixing and/or dispensing of chemicals, the mixing and/or dispensing of cleaning chemicals, the monitoring of plant cleaning operations, the usage of plant products/treatments/chemicals, and/or any other aspects associated with the operation of a dairy plant. The system is preferably able to monitor a dispensing system associated with a dairy plant.

An injection nozzle for a spray device for drawing in a fluid suction medium by a fluid propellant which is under excess pressure and for spraying an admixture of the suction medium and the propellant. The injection nozzle has a nozzle housing, an injection chamber arranged in the nozzle housing, a jet nozzle which opens in the injection chamber for producing a propellant jet which is introduced into the injection chamber, and a fluid suction opening for the fluid suction medium. The fluid suction opening opens in an annular channel which has a flow connection to the injection chamber.

A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.

Contrivances for dispensing or applying biologically active compositions such as insecticides and herbicides. More particularly, a system is provided that is capable of dispensing or applying a composition from a selection of available compositions and at a required concentration. In one version, the system includes first and second concentrate reservoirs, a diluent reservoir, and a diluent composition conduit. The system is configured such that a diluent in the diluent reservoir is mixed with a concentrate of the first or second concentrate reservoir to form a diluted composition. The diluted composition is prepared to a specified concentration by mixing the concentrate and diluent in appropriate proportions.

A solution applicator assembly comprises an upper body defining an upper channel. The upper body further includes a primary inlet fluidly connected to the upper channel. A lower body defines a lower channel being fluidly connectable to the upper channel to define a central channel. The lower body further defines a primary outlet fluidly connected to the lower channel. A flow control insert is removeably receivable in the central channel for receiving a chemical solution from the upper channel and releasing the solution into the lower channel. The upper body and the lower body are removeably connectable to one another to selectively allow the flow control insert to be removed and positioned in the central channel.

An undercarriage washing assembly includes a base that may be rolled along a support surface. Thus, the base may be rolled beneath an undercarriage of a vehicle. A plurality of wheels is provided. Each of the wheels is rotatably coupled to the base to roll along the support surface. A handle is movably coupled to the base. A spray unit is coupled between the handle and the base. The spray unit may be coupled to a fluid source to deliver a fluid onto the undercarriage thereby facilitating the undercarriage to be cleaned. The spray unit includes a reservoir. The reservoir may contain a detergent thereby facilitating the spray unit to deliver the detergent to the undercarriage.

Container assemblies (100) that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion (110) having an open end (113), and a lid portion (120) adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (140). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.
