A foam dispensing apparatus and system thereof can be used for dispensing a mixture of a resin component and an isocyanate component. The foam dispensing apparatus contains a heated hose assembly, a spray gun containing a spray head and a mix tube, and a nozzle for dispensing the resin and isocyanate components from the spray gun. Components of the foam dispensing system are lightweight and/or low cost thereby facilitating use and maintenance.

A nozzle for dispensing a beverage includes a nozzle head having a base liquid inlet configured to receive a base liquid and a flavoring inlet configured to receive a flavoring. The nozzle further includes a diffuser assembly that is in fluid communication with the base liquid inlet and which includes a diffuser plate having a plurality of peripheral openings through which the base liquid flows. The nozzle further includes a receptacle that is in fluid communication with the diffuser assembly and the flavoring inlet. The receptacle of the nozzle includes an inner wall, and the peripheral openings of the diffuser assembly are arranged so as to direct flow of the base liquid along the inner wall of the receptacle. The receptacle further includes an outlet through which the flavoring and the base liquid are dispensed.

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.

A foam output device, such as a dispenser, a gun, a turreted cannon, a hose adapter, an aerosol can, or others. The foam output device includes a valve configured to switch between a first mode and a second mode. The valve is configured to simultaneously receive a plurality of compositions and a fluid during the first mode such that the compositions and the fluid are able to react with each other within the valve to form a foam thereby. The valve is configured to prevent the compositions and the fluid from reacting with each other in the valve during the second mode.

An applicator for a coating product comprising printing nozzles, each including an outlet channel emerging in the downstream direction by a coating product discharge orifice. The printing nozzles are distributed on at least two faces of a body of the applicator and the discharge orifices of these nozzles extend along at least two nonparallel planes.

The present invention provides a portable device for injecting repair material, the portable device comprising: a chassis frame; tanks storing source materials; pumping means pumping the source materials; an injection nozzle mixing the source materials and injecting repair material into cracks; source material supplying means including: operating blocks connected to the pumping means; supplying pipes connected to the operating blocks and supplied with the source materials; transferring pipes connected to the operating blocks and transferring the source materials into the injection nozzle, and a pressure controller connected to the transferring pipe and controlling the source materials, wherein check valves for preventing backflow are installed inside the transferring pipes, wherein by adjusting another check valve connected to the pressure controller, an amount of the repair material for injection is controlled.

An indoor gardening appliance includes a grow module that is rotatably mounted within a grow chamber and that defines pod apertures for receiving a plurality of plant pods. A hydration system includes a nozzle assembly for selectively discharging a nutrient mixture from a mixing tank to hydrate plants within the grow chamber. The nozzle assembly includes a hydraulic cylinder including a piston positioned within a cylindrical chamber. An actuator moves the piston to a fully retracted position to draw in enough nutrient mixture for a single hydration cycle and then moves to a fully extended position to discharge the nutrient mixture. An intake check valve prevents undesirable backflow into the mixing tank and a discharge check valve prevents undesirable backflow into the cylindrical chamber.

A method for producing a layer of a device for electromagnetic radiation absorption, includes: providing a ply of powder material in the layer to be produced of the device; providing a predefined concentration distribution of particles for electromagnetic radiation absorption in the layer; providing a first binder and a second binder for the powder materials, wherein the first binder includes particles for the absorption of electromagnetic radiation, wherein the second binder includes a lower concentration of identical and/or different particles than the first binder; determining a mixing ratio between the first binder and the second binder for every position in the layer; selecting a position of the layer; mixing the first and second binder according to the mixing ratio for the selected position; wetting the powder material at the selected position using the mixed first and second binders; and repeating selecting, mixing, and wetting to produce the layer.

A fluid delivery system includes a smart hose. The smart hose includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose. The fluid delivery system further includes master hub disposed on a fluid delivery device. The fluid delivery system also includes at least one slave hub disposed on the smart hose and communicatively coupled to the master hub.

Systems and methods for performing serial crystallography by providing an aqueous suspension of a crystal sample to a T-junction at a first flow rate and providing an immiscible oil fluid to the T-junction at a second flow rate. The aqueous suspension and the oil are combined at the T-junction to produce a co-flow output fluid including a parallel co-flow of the aqueous suspension and the oil in the same output channel. The co-flow output fluid is ejected as a jet stream through a nozzle and the sample flow rate in the crystal sample in the jet stream is adjusted by adjusting the first flow rate of the aqueous suspension and the second flow rate of the oil. By combining the aqueous sample and the oil in this manner, the output of the jet stream can be regulated for compatibility with X-ray free electron laser serial crystallography.
