The system can also include a fuel inlet valve which is connected to the fuel chamber, and includes a connector for connecting to the fuel inlet; a fuel outlet valve which is connected to the fuel chamber and including a connector for connecting to the fuel outlet. The system can further include a platform having a memory reader/writer that reads the information in memory and is capable of writing information on memory, and on which the portable additive source is placed; and at least one control unit which is connected with the memory reader/writer, which includes a user interface device for receiving control information from the user, and which controls the operation of the safety and injection system.

A carbonator (100) for producing carbonated beverage including a first connector (11) for a gas-outlet (105) of a CO2-container (104) and with a CO2-valve (12), operable between a closed state and an open state, a second connector, a venting valve, an operating mechanism, and a manipulator (103), coupled to the operating mechanism (80), for allowing a person to operate the operating mechanism (80) between: a start mode (I) in which the venting valve (40) is open and the CO2-valve (12) is closed, and an end mode (III) in which the CO2-valve (12) is open and the venting valve (40) is closed, whereby the operating mechanism (80) is configured to be set in an intermediate mode (II), between the start mode (I) and the end mode (III), in which both the venting valve (40) and the CO2-valve (12) are closed.

A mixing assembly, device, system and method for operating are provided which includes a powder assembly holding a first container containing a powder, the powder assembly having a powder dispensing means for dispensing a predetermined quantity of the powder, a liquid assembly holding a second container containing a liquid, the liquid assembly having a liquid dispensing means for dispensing a predetermined amount of the liquid, and a mixing bowl for receiving the predetermined quantity of the powder and the predetermined amount of the liquid.

A liquid delivering system for wafer cleaning equipment includes an acid scouring tank, a sulfuric acid supplying source, a hydrogen peroxide supplying source, a first mixing device, a second mixing device and a feedback-control panel. The first mixing device and the second mixing device both includes a mixing duct, a multi-section mixing screw rod arranged inside the mixing duct and a heater wrapped around the mixing duct. By ways of adopting the above-mentioned technical solution, it is possible to realize fully mixing sulfuric acid with hydrogen peroxide in a mode of mixing in multi-stages, achieve precise control to temperature, and enable mixed liquid to fully react, thereby ensuring that the mixed liquid coming into the acid scouring tank meets cleaning requirements, and improving quality and efficiency of cleaning wafers.

Provided is a chemical injection system for connection to a chemical tank and a process line. The system includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

A blending device having an interlock system which may comprise a plurality of subassemblies. A thermal detector may be configured to be proximity with matter being blended for human consumption. Interlock system may further include a blade interlock contact and a compressive contact. The blender vessel may be configured to compress the compressive contact to a communicative configuration when connected with the blade assembly. Interlock system may utilize a blender base assembly that has base interlock contacts and a motor. The blade assembly may be configured to releasably mount to the blender base assembly and may cause the base interlock contact and the blade interlock contact to come into electrical communication with each other. The interlock system may ultimately result in the motor being obstructed from operation unless certain conditions are met. The interlock system may further utilize one or more than one logic circuit element.

A method of operating a blender having a rotatable cutting blade in a food preparation chamber includes providing a sensing light assembly, generating at least one sensing light beam below the food preparation chamber, inserting a cup containing food to be blended into the food preparation chamber, generating an error signal if a foreign object crosses the sensing light beam, and preventing or stopping rotation of the cutting blade in response to the error signal.
