  • Patent number: 11802244
    Abstract: The gemini surfactant for use in recycling lithium batteries is an anionic surfactant having the generic formula CxH2x+1(CyH2y+1) PO4CzH2zPO4CxH2x+1(CyH2y+1). An example of the surfactant is shown as compound 1 below where (x=5, y=2, z=4). Current solvents used to remove polymer binders include Nmethyl-2-pyrrolidone (NMP), N—N-dimethylformamide (DMF), N—N-dimethylacetamide (DMAC), N—N-dimethylsulfoxide (DMSA), and ethanol. The benchmark solvent often used to dissolve polymer binders is NMP. However, the present surfactants are phosphate-based surfactants and are used with a phosphate-based solvent, namely, triethyl phosphate (TEP), which is cheaper and more environmentally friendly than NMP. However, TEP has weaker binder solubility than NMP. Thus, the present surfactants are used with sonication to remove polymer binders.

  • Patent number: 8162110
    Abstract: An apparatus for automatically equalizing the uneven tension between ropes of an elevator in combination with a load cell to determine elevator load. The load of an elevator car having multiple tension members is automatically balanced while load is measured using a single load cell. The incorporation of a load cell with an autobalancing system allows for an accurate measure of an elevator load to be taken while providing the benefits of having uniform rope lengths in the elevator system. The apparatus may have various arrangements, including an in-line configuration and a grouped configuration. The apparatus may also dampen the vibration energy that is usually imparted to an elevator car.

  • Patent number: 8096024
    Abstract: Disclosed is a termination device for an aramid-based elevator rope having a high breaking strength. The termination device comprises a socket having a cylindrical, tapered internal passageway adapted to receive a corresponding wedge. The wedge includes a semi-cylindrical passageway in a substantially helical configuration to increase the surface area between the associated rope and the wedge. The termination device clamps the length of rope between tapered portions of the socket and the semi-cylindrical passageway of the wedge with a substantially uniform application of force on the cross-section of the rope.

  • Publication number: 20110165213
    Abstract: An insecticidal polymer matrix containing HDPE (high density polyethylene), LDPE (low density polyethylene), preferably containing PBO (Piperonyl Butoxide) and DM (Deltamethrin), wherein the ratio of the contents of HDPE to LDPE is between 5 and 20 and most preferably between 8 and 10. The matrix is highly useful for bed nets against mosquitoes.
