  • Patent number: 11325308
    Abstract: In an example implementation, a powder metering device to move powder in a 3D printing system includes a rotor comprising a central hub and peripheral wheel to rotate about a shaft. Compartments are formed between the hub and the wheel by a plurality of fins that emanate from the hub at first fin ends and affix to the wheel at second fin ends. A top and bottom disk each have a planar surface to lie flush against and to seal, respectively, top and bottom perimeters of each compartment as the compartments rotate about the shaft between a powder receiving position and a powder dispensing position.

  • Publication number: 20210094233
    Abstract: A 3D printing system comprises a pressure system to provide a negative pressure and a hopper having a first opening to receive powder to be used for printing, wherein the powder is received in an open state of the first opening. The hopper has a second opening to guide air from outside the hopper to inside the hopper and has a third opening connected to the pressure system so as to provide for a negative pressure inside the hopper, the negative pressure to overcompensate for the air receive through the second opening such that a pressure being lower when compared to an ambient pressure of the hopper is generated inside the hopper.

  • Patent number: 7434941
    Abstract: An arc lamp system includes an arc lamp, having a life span, a power supply, and a power control servo. The power supply is electrically coupled to the arc lamp and configured to provide power thereto, and the power control servo is coupled to the power supply, and configured to cause the power supply to provide lower power to the arc lamp at a beginning of the life span, and to provide greater power to the arc lamp toward an end of the life span.

  • Publication number: 20080116778
    Abstract: A lamp assembly for a projector includes first and second heat sinks and a non-electrically-conductive barrier disposed between the first and second heat sinks so as to prevent electrical arcing between the heat sinks. A method of making a lamp assembly includes disposing an electrically insulating barrier between two adjacent heat sinks of the lamp assembly so as to prevent electrical arcing between the heat sinks.
