A slurry dispense system utilizes a buffer chamber to release the pressure from the supply pump, and buffer the irregular flow rate of the supply pump. It also utilizes a positive displacement pump to control the dispense flow. With the help of the buffer chamber, the positive displacement pump is able to provide a constant flow rate, and can be accurately controlled. A high resolution and a high speed can be achieved at the same time.

A fluid-agitating tank assembly is disclosed. The tank assembly includes a tank filled with a fluid, and an agitator disposed in the tank so as to be at least partially immersed in the fluid and supported by the tank in a rotatable manner about an axis. The agitator includes a double helix disposed in an upper volume of the tank and adapted to act on the fluid to transform unidirectional rotation of the agitator about the axis into a bidirectional movement of the fluid in the tank towards bottom and top portions of the tank, and at least one rotary blade projecting transversally from the axis, disposed in a lower volume of the tank, and rotating about the axis to move the fluid towards at least one lateral outlet of the tank.

An injecting machine includes an injection cylinder, a plunger, a plunger moving mechanism, and a mixing mechanism. The plunger is reciprocally received in the injection cylinder for moving between an advanced position and a retracted position, with the injecting a liquid mixture of two different liquid materials as the plunger moves to the advanced position. The plunger moving mechanism causes the plunger to move between the advanced position and the retracted position. The mixing mechanism is disposed on the injection cylinder for mixing the two different liquid materials together to feed the liquid mixture into the injection cylinder. The plunger includes a front portion having a helical groove formed on an outer circumferential surface thereof to allow the liquid mixture fed from the mixing mechanism to pass through the helical groove for collecting in a forward space formed forward of the front portion of the plunger.

A vacuum deaerator degasses material to be processed by placing a rotating rotor with a screen in a vacuum vessel, introducing a liquid material to be processed into the rotor from the interior thereof and causing the liquid to pass through the screen to refine the same. The vacuum deaerator is characterized in that: the screen is a cylinder with a circular cross-section and is in the form of a porous plate in which a plurality of through holes are opened in the radial direction of the cylindrical screen; and the screen is provided such that the area of inflow openings is greater than the area of outflow openings, where the inflow openings are openings of a plurality of penetration portions provided on the inner wall face of the screen and the outflow openings are openings of the plurality of penetration portions provided on the outer wall dace of the screen. Thus, the processing capacity of the vacuum deaerator is improved without increasing the size of the device.

Embodiments relate to an insulation filling device for a fuel reformer, comprising: a feeder for supplying a powder insulation material; a stirrer for mixing the powder insulation material with a liquid binder for the agglomeration of the particles of the powder insulation material to form an insulation paste; and a thermal molding device for compressing said insulation paste to form a plurality of insulation molds having a predetermined shape and filling the insulation space of the fuel reformer with said insulation molds.
