An insulation material formed of a composition, and a method of making an insulation material is provided. The composition forming the insulation material includes magnesium oxide; at least one of magnesium chloride, magnesium sulfate, and hydrates thereof; water; a foaming agent; a thickener; and a foam stabilizer. The composition is foamed to promote aeration of the composition to reduce density of the insulation material formed from the composition.

A distribution tube for a static mixer provides efficient mixing with improved performance over a wide range of flow rates. The distribution tube is positioned near an inlet side of the static mixer. An injected fluid is introduced into the static mixer via the distribution tube, which pre-mixes the injected fluid with a main fluid prior to further mixing by mixing elements of the static mixer.

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.

A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.

The present disclosure relates to an in vivo duct repair device and an operating method thereof. The in vivo duct repair device includes a catheter; a nozzle assembly, two axial ends thereof including a supplying end and a spraying end, respectively, the nozzle assembly having a first material flow channel arranged inside the nozzle assembly, a first material spout communicated with the first material flow channel and spraying a first material radially outwards, a second material flow channel arranged inside the nozzle assembly and isolated from the first material flow channel and a second material spout communicated with the second material flow channel and spraying a second material radially outwards, and the nozzle assembly being configured to enter the catheter and extend the spraying end out of an introducing end of the catheter; and a drive device connected to the supplying end.

An inline shower device includes a housing, a hydraulic chamber, a first actuator, and a fluid-driven piston. The housing includes an outlet port. The hydraulic chamber is disposed within the housing. The first actuator is configured to connect a capsule to the housing and to fluidly connect the capsule to the hydraulic chamber. The fluid-driven piston is disposed within the hydraulic chamber and is configured to dispense a fluid from the capsule into the outlet port.

A system and method for delivering materials for deposition is described. The system includes reservoirs for holding materials, heating elements for liquefying the materials (unless they are to be delivered as solids). Once in a desired state, pressure and material delivery systems to move the materials to a deposition nozzle. In the deposition nozzle, or thereabouts, the materials combine and are prepared to be deposited. An agitation element is used to break up the material and push it out of the nozzle tip in an atomized or droplet form. Changes in the material composition/concentration result in adjustment in heat, pressure or deposition agitation.
