  • Publication number: 20200136129
    Abstract: A drop-on-demand printable ink composition for a cathode of a solid-state lithium ion battery. The ink composition includes a cathode material configured to conduct lithium ions, a polymeric binder, and a solvent. The polymeric binder has a number average molecular weight ranging from about 5 kDa to about 5 MDa and the solvent has a boiling point under standard atmospheric conditions ranging from about 50° C. to about 225° C. A ratio of solid material to solvent ranges from about 1:100 to about 40:60 and a viscosity of the ink composition ranges from about 5 mPa·s to about 40 mPa·s.

  • Publication number: 20190305359
    Abstract: A printable ink formulation for a solid lithium ion electrolyte. The printable ink composition includes a solvent having a boiling point under standard atmospheric conditions ranging from about 50° C. to about 225° C., a polymer, and a lithium salt. The composition is stable, has a viscosity ranging from about 1 mPa·s to 2000 mPa·s, and is printable by a drop-on-demand printer.

  • Publication number: 20120184911
    Abstract: A method, apparatus, and kit for marking the opening between the fallopian tube and the uterus (tubal ostia) are provided. A marking dye provided in a marking assembly including a fluid dispenser coupled to a catheter having an open end and a guide wire. The catheter is inserted into the uterus and to a position adjacent the tubal ostia. When properly inserted, the fluid dispenser is activated to cause fluid to flow through the catheter and to the wall of the uterus to provide a mark. Once the mark is provided, endometrial ablation process can be provided in the uterus. The marks can then be used to guide the insertion of tubal occlusion devices.

  • Patent number: 5492216
    Abstract: A method and apparatus enable horizontally transporting a succession of objects, such as glass bottles, without bottom support and yet maintaining precise, consistent centerline location. A pair of continuous transport belts are supported, preferably by a pair of complimentary interlocking belts, to maintain a substantially constant distance between the facing object-supporting surfaces. Preferably, the interlocking belts are made of alternating teeth and grooves transverse to the horizontal transfer path. The belts are rendered substantially inextensible transverse to the direction of the path.
