  • Patent number: 10232130
    Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may have a plurality of pores through which the liquid flows, and may be formed of a hydrophilic material that resists passage of air through the pores. The intravenous delivery system may further have a bubble point raising component that raises the bubble point of the anti-run-dry membrane. The bubble point raising component may, in some embodiments, be a high surface energy coating or additive.

  • Patent number: 10224258
    Abstract: A method for densifying thermoplastics, particularly polyimides, for use in conjunction with electronic circuits while producing improved physical properties and a high degree of crystallinity, involves variable frequency microwave (VFM) processing at temperatures typically 100° C. below the glass transition temperature or lower, for times of about 50 to 100 minutes. It is particularly applicable to polymers based on BPDA-PPD, but may also be generally applied to other intentionally designed polyimide structures with the same features. The invention enables the creation of layered structures involving integrated circuits with small feature sizes and overcoatings of polymers with high Tg and other desirable properties.
