  • CELL-ISOLATING DISPENSERS
    Publication number: 20250186992
    Abstract: A cell-isolating dispenser can include a fluid reservoir, a foyer, and a thermal ejector. The foyer can be fluidically coupled via a fluid outlet to the fluid reservoir. The foyer is configured to receive a cell-containing fluid from the fluid reservoir and has a wall that is optically transparent or a portion of a wall that is optically transparent. The thermal ejector is fluidically coupled to the foyer to receive the cell-containing fluid from the foyer and operable to thermally eject a droplet of the cell-containing fluid through a nozzle via a thermal actuator.

  • Chipper device and method for chipping metal ingots
    Patent number: 7770832
    Abstract: A chipper device for chipping one or more metal ingots. The chipper device includes a cutter head and a guide mechanism associated with the cutter head. The guide mechanism includes a chute having a passageway. A feed mechanism is adapted to move one or more ingots sequentially through the passageway of the chute into engagement with the cutter head, whereby the cutter head chips the ingots into a plurality of particles.
