A mixing apparatus includes a mixing tank configured to receive substances, a rotor arranged in the mixing tank capable of driving a vane to rotate about an axial direction, a stator arranged outside the mixing tank and capable of driving the rotor to contactlessly magnetically rotate about the axial direction and capable of magnetically supporting the rotor with respect to the stator, and a security against tilting device that includes a bar extending in the axial direction and rotationally fixedly connected to the rotor, the security against tilting device having a limiting element fixed with respect to the mixing tank and cooperating with the bar, the security against tilting device being configured such that the bar is capable of rotating with respect to the limiting element and tilting of the rotor is limited by physical contact between the bar and the limiting element.

Syringe for dispensing foam having a syringe barrel, a nozzle and a bore to receive a syringe plunger having a front end and a back end. The syringe plunger includes at the front end thereof a waste container defined by a cylindrical side wall, a front end wall and a rear end wall, the walls being arranged such that an external cylindrical surface of the walls forms a seal with an internal surface of the syringe barrel. The waste container has an inlet aperture in the front end wall which is in communication with the syringe nozzle when the plunger is fully depressed into the syringe barrel. The waste container further has a hydrophobic vent in the rear end wall thereof which allows air to escape from the waste container while substantially preventing foam from escaping the waste container when the syringe is in use.

A laboratory mixer for mixing a sample and a diluent in a bag. An enclosure defines a mixing chamber, and at least one movable mixing element is retained for mixing the sample and the diluent within the bag. At least one liquid detector is retained relative to the enclosure for detecting liquid leaked from the bag. The sensor can be a capacitive, inductive, or optical sensor. The sensor can be a conductivity sensor with two electrodes shaped like combs and a gap less than or equal to a diameter of a drip of diluent solution. A ledge with a low point can be retained by an access door. The sensor or sensors can be disposed adjacent to the access door, on a mixing element, in direct contact with the bag, or on a tank. An alarm and cessation of operation can be triggered upon a detection of leaked liquid.

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 mixing apparatus which can reliably prevent an auxiliary liquid from being unintentionally mixed into a main unit even when a failure occurs in a switching device, and which can prevent the switching device or an auxiliary flow route from being damaged even when a pressurizing device malfunctions due to the failure. The mixing apparatus includes a pipe circulating dilution water; a pipe circulating a disinfecting solution; a pressurizing pump circulating the disinfecting solution in the pipe toward the pipe; and a check valve capable of optionally turning on and off the pipe. The mixing apparatus further includes a discharge flow route which consists of a flow route branched from between the check valve and the pressurizing pump in the pipe, and which can discharge the dilution water or the disinfecting solution; and an electromagnetic valve which can control the flow route between the check valve and the pressurizing pump in the pipe to have a pressure lower than that of the pipe when not mixing the disinfecting solution with the dilution water.

Some variations provide a system for producing a functionalized powder, comprising: an agitated pressure vessel; first particles and second particles contained within the agitated pressure vessel; a fluid contained within the agitated pressure vessel; an exhaust line for releasing the fluid from the agitated pressure vessel; and a means for recovering a functionalized powder containing the second particles disposed onto surfaces of the first particles. A preferred fluid is carbon dioxide in liquefied or supercritical form. The carbon dioxide may be initially loaded into the pressure vessel as solid carbon dioxide. The pressure vessel may be batch or continuous and is operated under reaction conditions to functionalize the first particles with the second particles, thereby producing a functionalized powder, such as nanofunctionalized metal particles in which nanoparticles act as grain refiners for a component ultimately produced from the nanofunctionalized metal particles. Methods for making the functionalized powder are also disclosed.

An inerting system for an aircraft and a method of inerting a hydrogen system in an aircraft. Also an aircraft with such an inert system. In the inerting system, a part of an inerting gas that has already been supplied to the casing of the hydrogen system is mixed with pure inerting gas through a fluid recirculation system.

A blender system may include a skid and a blender assembly, the blender assembly including a blender tub. Further, the blender system may include a cable passthrough interlock cabinet. The cable passthrough interlock cabinet includes a first articulating access panel, the articulating access panel having a panel plate and cable notches cut or formed into the panel plate. The cable passthrough interlock cabinet also includes an enclosure, the enclosure connected to the articulating access panel, the enclosure having a face and an interior, with cable holes in the interior and a latch, the latch disposed on the articulating access panel. Also, the cable passthrough interlock cabinet may include a strike plate, the strike plate positioned on the face of the enclosure, the strike plate corresponding to the latch.
