  • Publication number: 20230088092
    Abstract: A photoactive cluster particle for durable latex paint compositions and said durable paint compositions, the photoactive cluster particle including a binder that coalesces cluster components into a cluster particle. The cluster components of the cluster particle include a photoactive component, one or more silicon-containing particles (may act as the binder), optional discrete polymeric particles each defining a closed void volume therein, optional non-photocatalytic inorganic pigment particles, optional organic latex polymer, and optional extender pigment particles. The photoactive cluster particle further includes an interstitial void network of the cluster particle forming a porosity thereof.

  • Patent number: 8409145
    Abstract: An insertion device for inserting an infusion device at least partially into skin for subcutaneous infusion can comprise a sleeve having a lower surface that is configured to engage the skin, a shuttle or carriage to carry the infusion device between a retracted position and an advanced position; at least a first biasing member to urge the shuttle or carriage toward the advanced position, and an actuator to cause the first biasing member to urge the carriage from the retracted position to the advanced position. In some embodiments, the insertion device can further comprise a hub and at least a second biasing member to urge the hub away from the shuttle or carriage. In some embodiments, the insertion device can further comprise a needle attached to the hub. Methods for inserting an infusion device and various other features that can be comprised by an insertion device are also disclosed.

  • Patent number: 8277703
    Abstract: The smoke suppressant comprises a molybdate precipitate on the surface of a borate core. The precipitate increases surface area of the core and provides improved smoke suppression relative to a mixture of the molybdate and borate core. The suppressants can be incorporated into polymer compositions to improve their smoke suppression capability.

  • Patent number: 8070990
    Abstract: The present invention is directed to smoke suppressants based on ammonium octamolybdate chemistry. According to this invention, the precipitation of ammonium octamolybdate in the presence of an inert mineral core produce a novel high surface area ammonium octamolybdate smoke suppressant. The high surface area significantly increases the smoke suppression performance over a standard ammonium octamolybdate. This invention is also directed to a process for making the high surface area ammonium octamolybdate smoke suppressant. The smoke suppressant of this invention is particularly suitable for smoke suppression in polyvinyl chloride (PVC) applications.
