  • PRELOADED SURGICAL INSTRUMENT INTERFACE
    Publication number: 20240090958
    Abstract: A surgical system includes a surgical instrument that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument is coupled to motors in a surgical instrument manipulator assembly via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly. From the drive output disk in the surgical instrument manipulator assembly to the driven disk of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.

  • Efficiency of ultrafiltration purification of solutions of polymeric colorants by inorganic base addition
    Patent number: 4225432
    Abstract: The ultrafiltration purification of aqueous solutions of polymeric colorants, wherein low molecular weight impurities are removed in an ultrafiltrate leaving a purified polymeric colorant-bearing retentate, is carried out with improved efficiency when during at least 2 diavolumes of ultrafiltration, the pH of the retentate is maintained above about pH 9.0.
    Type: Grant
    Filed: November 18, 1976
    Date of Patent: September 30, 1980
    Assignee: Dynapol
    Inventors: Robin G. Booth, Anthony R. Cooper
  • Salt addition in ultrafiltration purification of solutions of polymeric colorants
    Patent number: 4189380
    Abstract: The ultrafiltration purification of aqueous solutions of polymeric colorants, wherein low molecular weight impurities are removed in an ultrafiltrate leaving a purified polymeric colorant-bearing retentate, is carried out with improved efficiency when, during at least two diavolumes of ultrafiltration, the salt content of the retentate is maintained above about 1% by weight.

  • Ultrafiltration purification of solution of polymeric anthraquinone colorants
    Patent number: 4088572
    Abstract: The ultrafiltration purification of aqueous solutions of polymeric anthraquinone colorants, wherein low molecular weight impurities are removed in an ultrafiltrate leaving a purified anthraquinone colorant-bearing retentate, is carried out with improved efficiency when pyridine is present and maintained in the aqueous solutions at a level of from 1 to 20% by volume.
