  • Patent number: 11591661
    Abstract: An example system for purifying a supply stream including lactose includes a clarification system configured to separate insoluble impurities from the stream to produce a clarified stream. The system includes an adsorption system fluidically coupled to the clarification system. The adsorption system includes an adsorbent resin configured to purify the clarified stream. An example technique for purifying a supply stream including lactose includes separating insoluble impurities from the supply stream to produce a clarified stream and passing the clarified stream over an adsorbent resin to produce a decolorized stream.
    Type: Grant

  • Patent number: 6926461
    Abstract: A high-impact, energy-absorbing vehicle barrier system generally includes a substantially rigid outer containment wall coupled via cable restraint assemblies with an energy-absorbing inner impact wall, and energy-absorbing cartridges strategically positioned between the impact wall and containment wall. The impact wall is constructed of a number of rectangular tubes coupled with one another to presents a substantially smooth, uniform surface to passing vehicles. The energy-absorbing cartridges generally consist of a number of foam sheets which compress and crush between the containment wall and impact wall to absorb energy from an errant vehicle striking the face of the impact wall, while the deflection and deformation of the impact wall tubes dissipates additional energy to reduce peak decelerations and mitigate the severity of high-energy vehicular impacts.
