  • Publication number: 20180228145
    Abstract: The present disclosure is directed towards an absorbent binder composition that includes a hydrophilic polymer which has the capability of post-application, moisture-induced cross-linking. The absorbent binder composition can include 1) a superabsorbent polymer material which can include at least 15 mass percent monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, and an acrylate or methacrylate ester that contains an alkoxysilane functionality and 2) a polyvalent metal cation having a valence of at least two. Upon loss of water by evaporation, the alkoxysilane functionality forms a silanol functional group which condenses to form a crosslinked polymer. Upon exposure of the absorbent binder composition to a biological material, such as urine, blood, or feces, the biological material can interact with the polyvalent metal cation and can serve as a catalyst to accelerate the polymer cross-linking and gelation of the polymer.

  • Patent number: 9505991
    Abstract: There is provided an apparatus (1) and methods for processing biomass to produce charcoal, bio-oil(s) activated carbon, recarburizer carbon, or nut coke by means of microwave energy. The apparatus has a rotatable tube (5) for receiving biomass (108), an electromagnetic generator (7). One method provides applying electromagnetic energy to the biomass (108) and an absorbing material (109). An alternative method provides allowing an indirect, black body radiation field to develop, and exposing the biomass (108) to the black body radiation field and the electromagnetic energy. Another method provides allowing plasma to form and exposing the biomass to the plasma and the electromagnetic energy. Another method provides introducing the biomass to a second container (205), introducing the second container to a first reaction container (5), applying electromagnetic energy to the biomass and an absorbing material (109), allowing a plasma to form in the first container, which heats the biomass in the second container.

  • Publication number: 20140320029
    Abstract: A power converter circuit includes: a first transistor being connected with a positive node and a negative node of a photovoltaic panel; a second transistor being connected with the first transistor and the negative node of the photovoltaic panel; a first controller circuit being configured to measure the voltage at a reference node and adjust the gate voltage of the first and second transistors respectively; a third transistor being connected with the reference node and an output node; and a second controller circuit being configured to control the gate voltage of the third transistor. The reference node is connected to the second transistor through a LC network. The first controller circuit is configured to turn off the first and second transistors when the voltage at the reference node exceeds a threshold. The second controller circuit is configured to prevent current from being fed back through the LC network.

  • Publication number: 20070239793
    Abstract: A system and method for implementing storage management with threshold control is provided. A flexible storage manager associates storage devices having a similar performance characteristic into logical constructs called storage groups. Storage groups having the same performance characteristic from a plurality of storage systems are organized into storage pools. The flexible storage manager automatically provisions storage on a storage pool basis. Should a low threshold utilization be exceeded, the flexible storage manager performs a set of management policies to lower the utilization of a storage pool to the low threshold.
