A device for the treatment of strand-shaped textiles includes a treatment container, a transport nozzle array, and a transport path by way of which a material strand can be moved through the transport nozzle array in a transport direction. The transport nozzle array includes a transport nozzle with nozzle inlet and outlet orifices for the material strand, between which are delimited at least two nozzle gaps for a transport medium. At least one of the nozzle gaps is adjustable regarding its gap width. At least one nozzle gap can convey the material strand in the transport direction, and at least one nozzle gap can convey the material strand in a direction counter to the transport direction. The device also includes a control unit that selectively drives the material strand in the transport direction or in the direction counter to the transport direction by appropriate actuation of the nozzle gaps.

A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.

Atomizing nozzle which combines two or more substances introduced through at least a first inlet (10) and a second inlet (50), and sprays the resulting atomized droplets through an outlet (110), capable of optimized flow rate and droplet size through a modular design based on interchangeable disk-shaped modules. When stacked in a hollow cylindrical casing conformed by a first housing (20) and a second housing (120), the plurality of modules conform a first mixing chamber (200) and a second mixing chamber (210) connected through a swirl module (60). Furthermore, when said stacking occurs, the first inlet (10) is connected to the first mixing chamber (200), the outlet (110) is connected to the second mixing chamber (210); and the second outlet may be connected to the first mixing chamber (200) or the second mixing chamber (210) depended on the configuration selected by the user.

A gypsum slurry modifier device is provided for use with a gypsum mixer outlet boot having at least one tubular outlet leg, and includes a support bracket mountable to the outlet boot; at least one clamp member associated with the support bracket and constructed and arranged for engaging the at least one tubular outlet leg of the outlet boot. Each at least one clamp member is constructed and arranged for exerting a vertical compression force on the associated at least one tubular outlet leg for expanding a slurry outlet flow from the at least one leg laterally beyond an exterior surface of the leg.

The present disclosure involves apparatuses and methods for coating a lapping plate with an aqueous composition. The apparatus can be configured and the aqueous composition can be formulated so that the aqueous composition can flow to a spray nozzle device solely due to gravity in a batchwise manner.

The present invention embodies a spray nozzle for mixing and spraying a mixture of liquid and dry material. The device is comprised of a liquid injector, a torpedo, a spray tip, and a mixing chamber. The mixing chamber is connected to a hose that directs dry material through the apparatus. Dry material is forced around and over the first end of the torpedo within the mixing chamber, slowing the speed of that material and focusing it toward the second end of the torpedo where it mixes with liquid exiting the spray tip at this second end. The torpedo blends the dry and liquid components more uniformly resulting in a more homogenous material.

The present invention discloses a gas-powder separation three-phase jet flow fire monitor system, including a gas-powder separation three-phase fire monitor head, a filter, a nitrogen pressurization apparatus and a dry powder tank. The dry powder tank is connected to a powder feeding pipe of the gas-powder separation three-phase fire monitor head through a pipeline. A nitrogen outlet pipe of the gas-powder separation three-phase fire monitor head is connected with one end of the nitrogen pressurization apparatus through the filter. The other end of the nitrogen pressurization apparatus is connected with the dry powder tank. The present invention is simple in structure and convenient to use. A cyclone separation apparatus of a dry powder pipeline of the fire monitor may separate nitrogen from conveyed ultrafine dry powder to enable the ultrafine dry powder to be fully mixed with a water-based fire extinguishing agent, thereby reducing an atomization degree of jet flow and enlarging a range of the fire monitor. In addition, the separated nitrogen enters the dry powder tank for recycling after being pressurized by the pressurization apparatus, thereby reducing the fire extinguishing cost.

According to an embodiment, a method of applying loose-fill insulation within a cavity is provided. The method includes blowing loose-fill insulation particles into a cavity of a structure to install the loose-fill insulation within the cavity and thereby insulate the structure. The method also includes applying water (e.g., water mist) to the loose-fill insulation particles so that a moisture content of the installed loose-fill insulation is between about 2% and 20%. The water aids in retaining the loose-fill insulation particles within the cavity without requiring the use of an enclosure member that encloses the cavity and the loose-fill insulation is substantially free of a water soluble adhesive material that adheres the loose-fill insulation particles together within the cavity.

The present disclosure provides a sound absorbing material and a preparation method thereof. The sound absorbing material includes a porous powder core and an adhesive coating the porous powder core. A porous powder dispersion solution and an adhesive dispersion solution are simultaneously subjected to spray granulation via a nozzle having an inner ring nozzle and an outer ring nozzle, so that the porous particles having a structure including a porous powder core and an adhesive coating the porous powder core are formed. The porous particles prepared by the method of the present disclosure when serving as a sound absorbing material of a sounding device have high strength and is not easy to be broken. Moreover, a total amount of the adhesive used in the method of the present disclosure is less than that in the conventional method, so that cost is effectively saved.

A thermal spray system and method includes a hot gas generator with nozzle accelerating heated gas towards a substrate in the form of a gas column projecting onto the substrate surface as a spot. One or more feedstock injectors proximate the nozzle exit, directed towards the gas column, are connected to a feedstock source. The hot gas stream transfers heat and momentum to the feedstock, causing the feedstock particles to impact onto a substrate to form a coating. The system further comprises one or more liquid injectors proximate the nozzle exit, directed towards the axis, and connected to a source of liquid. The system controls the flow and velocity with which the liquid is injected, permitting control of the depth of penetration of the liquid into the gas column. The method selectively prevents suboptimal feedstock particulates from adhering to the substrate and provides for the in-situ removal of suboptimal deposits.
