  • Patent number: 11357227
    Abstract: A frame includes a ring-shaped body part locatable to surround the periphery of an organ, and at least one tube clamp part mounted on the body part. Each tube clamp part includes a tube holder that holds a tube. The tube clamp part is mounted so as to be movable in the circumferential direction of the body part. Thus, a tube connected to the organ can be fixed at an appropriate position to the tube clamp part. This stabilizes the relative positions of the organ and the tube. Accordingly, it is possible to reduce the probability of the organ becoming damaged due to a strain on the organ.

  • Patent number: 11338296
    Abstract: There is described a variable-temperature reactor for hosting a predetermined reaction therein. The reactor comprises a reaction cell, a heater, and a heat sink. The reaction cell has a reaction volume with thickness Hv and width Wv where Wv>4Hv and is defined by faces with one of the larger area faces of the reaction volume being bounded by an outer wall with thickness Hw. The heater is in contact with the said outer wall. The heater comprises a heat-generating heater element located on the face closer to the reaction volume and a heater support on the opposite face. The heater support is in contact with a heat sink, such that the heater support provides a thermal resistance RT between the heater element and the heat sink. The reactor, when filled with reagents having thermal diffusion coefficient Dv has a diffusion time tv, in the thickness direction, tv=Hv2/Dv. tv is less than the reaction time constant tR.

  • Patent number: 11326139
    Abstract: A system for aerobic fermentation includes a vessel, an aeration system including a gas sparger fluidly coupled to the vessel to introduce a compressed gas to an internal volume of the vessel, and a recirculation loop fluidly coupled to an outlet of the vessel. The recirculation loop includes an eductor fluidly coupled to an oxygen-containing gas source, a static mixer downstream of the eductor, a heat exchanger downstream of the eductor, and a distributor downstream of the heat exchanger. The distributor is fluidly coupled to the vessel. The aeration system provides mixing and oxygen mass transfer to the fermentation composition in the vessel. The fermentation composition passes through the eductor, static mixer, heat exchanger, and distributor of the recirculation loop, and back into the vessel. Oxygen is transferred from an oxygen containing gas to the fermentation composition and heat is removed from the fermentation composition in the recirculation loop.
