  • Patent number: 11767400
    Abstract: A process for the manufacture of a degradable polycyanurate bulk molding composition includes: contacting a liquid cyanate ester monomer with an additive material and a polymerization catalyst to form a reaction mixture; maintaining a temperature of the reaction mixture at about 80° C. to about 100° C. to form a polycyanurate product having a viscosity of about 120 to about 200 centipoise at 23° C.; heating a reinforcing filler at a temperature of about 50 to about 150° C. to form a pre-heated reinforcing filler; and blending the polycyanurate product with the pre-heated reinforcing filler to form the degradable polycyanurate bulk molding composition. The bulk molding composition can be used to form a degradable polycyanurate article.

  • Publication number: 20220003083
    Abstract: A fluid control device includes a support structure configured to be deployed in a borehole, and a filtration component disposed at the support structure, the filtration component including a porous medium made from a thermoplastic polymer material, the porous medium including an open cell foam. The porous medium has a porosity selected to cause the porous medium to exhibit shape memory behavior, and the porous medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.

  • Publication number: 20140282542
    Abstract: Two levels of address masquerading are employed to make a virtual appliance a transparent gateway between a hypervisor and a storage controller. This approach allows a virtual appliance to be inserted or removed from the IP storage path of a hypervisor without disrupting communications. One embodiment of the invention enables a virtual appliance to intercept, manipulate, reprioritize, or otherwise affect IP (Internet Protocol) storage protocols sent or received between a hypervisor and storage controller(s).
