Abstract: A thermal energy storage system utilizes a high temperature storage segment having flow passages extending through the storage segment whereby a working fluid can extract energy from the storage system for powering conventional downstream equipment. A mixing manifold cooperates with an outlet manifold for reducing the temperature of the working fluid to a temperature safe for the downstream equipment. The mixing manifold, an outlet manifold, an inlet manifold and a support base for the high temperature storage segment, are all of a high temperature tolerant material allowing the high temperature storage segment to operate at temperatures in excess of 1000° C. and preferably to temperatures above 1400° C. The temperature of the working fluid provided to the conventional equipment can be managed to be below a maximum temperature which in many cases may be about 700° C.

Abstract: A rotor-stator system for agglomerate mixing apparatus utilizes a unique rotor-stator mixer assembly which combines a high efficiency rotor with unique stator element designs to address the limitations of prior rotor-stator mixer assemblies, including the dispersal of large agglomerate and problem of heat build-up. The stator elements have a variety of slot openings in different sizes and shapes whose inside walls are slanted in an acute attack angle that will generate circumferential, rather than exit flow. These slot configurations enable rapid large agglomerate reduction into smaller and smaller agglomerates and ultimately down to particle size without the need to change stator configuration, which is already built into the device.

Abstract: The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.

Abstract: A device for shredding deep-frozen food products provided in block form comprises a tool coupled to one end of a rotatable shaft which rotates the tool about an axis of rotation and advances the tool along the axis of rotation in the direction towards the block, thereby scraping layers off the block. The tool can be uncoupled from and recoupled to the end of the shaft without using a tool. When the tool is coupled to the end of the shaft it axially abuts the shaft's end and is thereby held in a force-locking manner on the end of the shaft for the transmission of drive forces from the shaft to the tool. The device includes a tool detection device to determine whether a tool is arranged on the end of the shaft as intended so that operation can occur only when the tool is connected as intended.

Abstract: In a continuous centrifuge, a core end surface component separated from a core body is arranged inside a rotor, an air trap mechanism which automatically captures bubbles inside a sample is formed, and the bubbles are removed by centrifugal separation before the sample is sent to an outer circumferential portion having a high liquid pressure. In addition, when viewed in the axial direction, the core body and an upper rotor cover abut each other, and the core end surface component and a lower rotor cover abut each other, with appropriate pressure by biasing the core end surface component and the core body with a spring. Because a flow path between the rotor core and the rotor covers is maintained in a perfect state and the bubbles in liquid are also removed, the flow path may not be blocked by the bubbles and the centrifugal separation can be stably performed.
