An insert device includes a first coupling body inserted into an engine cylinder head. The first coupling body extends around a center axis to define a first interior volume of the first coupling body that is shaped to receive a distal tip of a fuel injector. The insert device includes a second mixing body coupled with the first coupling body and extending around the center axis. The second mixing body includes conduits that receive fuel from the fuel injector and air from a combustion chamber, combine the fuel with the air, and direct the fuel-air mixture into the combustion chamber. The first coupling body has a first end surface positioned to face the cylinder head and the first coupling body is tapered such that an outer diameter of the first coupling body is larger toward the first end surface than toward the second mixing body.

A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

A dosing dispenser system and a dosing dispenser include a rotatable control configured to allow a user to select a desired mixing ratio for a product contained in a container attached to the dosing dispenser with a transport medium, such as water, flowing through the dosing dispenser.

The invention provides novel systems and methods for liquid-mediated delivery of pollen to a female reproductive part of a recipient plant. The systems provided herein include a container configured to receive a liquid pollen suspension solution, and an applicator attached to the container configured to spray the liquid pollen suspension solution onto the recipient plant. The methods provided herein include spraying a liquid pollen suspension solution onto at least a first female reproductive part of a recipient plant using the system provided herein, thereby pollinating the recipient plant.

There is provided a spray gun configured to atomize a liquid by using a compressed gas. The spray gun comprises: a gas cap configured to inject the compressed gas; and a liquid nozzle configured to inject the liquid, wherein the gas cap comprises a center gas flow path that has an opening provided in a neighborhood of the liquid nozzle; and multiple pairs of side face gas ports provided outside of the opening, each pair of the side face gas ports being placed at positions symmetric to each other across a center of the liquid nozzle and being directed toward a center in an injecting direction of the liquid nozzle, and wherein control is made to individually regulate a pressure of the gas to be injected from each pair of the side face gas ports.

A spraying device includes a spray head, which is connected to a supply line, via which a pressurized fluid can be conveyed. The spraying device includes a metering screw for influencing the fluid jet passing out of the spray head. The spraying device is designed such that a pointer element having at least one marking is connected to the metering screw in a rotationally fixed, yet detachable manner.

The invention relates to a dispensing device which is intended for spraying a sprayable fluid and is designed in the form of a hand-held unit, having a housing (12), in which are provided an air pump (22) and an electric drive motor (18), which drives the air pump (22), having a spray head (14), which is connected to the housing (12) and is intended for dispensing the fluid, having an accommodating chamber (29), which is arranged in the housing (12) and is intended for a storage container (41), in which the fluid which is to be dispensed is stored, having a fluid line (44), which leads from the storage container (41) to the spray head (14), and having a hose line (36), which leads from the air pump (22) to the spray head (14), wherein the spray head (14) has a first nozzle (46), which is connected to the fluid line (44), and, separately from said first nozzle, a second nozzle (38), which is supplied with the air flow from the hose line (36), and an atomizing zone (49) is formed outside the spray head (14).

A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.
