  • Patent number: 7389073
    Abstract: A development station in an electrostatographic imaging machine supports longer operational life without undue variation in the mass of developer on roll parameter. The development station includes a developer housing, for retaining a quantity of developer having semi-conductive carrier particles and toner particles, a first magnetic roll having a stationary core with at least one magnet and a sleeve having longitudinal grooves that rotates about the stationary core of the first magnetic roll to transport developer to a photoreceptor, a second magnetic roll having a stationary core with at least one magnet and a sleeve having longitudinal grooves that rotates about the stationary core of the second magnetic roll to receive developer from the first magnetic roll and present the developer to the photoreceptor, the sleeve of the second magnetic roll being fabricated from a material that is softer than the sleeve of the first magnetic roll.

  • Patent number: 7377665
    Abstract: A belt buckle with an embedded power source, such as battery(s), and an attached or embedded light source, such as light emitting diodes, for illuminating an area in front of a user, such as a hiker, climber, or trail-runner. The buckle is typically a side-release plastic buckle, and is typically mounted centrally on a pack's hip-belt. The light is adjustable vertically, or has a lens to produce a tall, narrow beam of light for the purpose of illuminating a large section of trail.
