Jimmie B Allred III, Allan I Krauter: Self-adjusting steering mechanism for borescope or endoscope. Welch Allyn, Wall and Roehrig, August 9, 1988: US04762119 (58 worldwide citation)

In a cable-steerable endoscope or borescope, in which opposing cables are displaced to deflect the tip of the endoscope or borescope, a self-adjusting mechanism in the control section ensures a maximal differential force and a minimal total force is applied to the two steering cables. The self-adjus ...

Allan I Krauter, Michael P Kehoskie, Robert L Vivenzio: Torque override knob for endoscopes, borescopes, or guide tubes. Welch Allyn, Harris Beach & Wilcox, March 5, 1996: US05496260 (44 worldwide citation)

A manually rotated knob drive mechanism incorporates a torque override feature. If the knob turning force exceeds a predetermined torque limit the feature permits slippage between the knob and the associated stem or drive shaft. The knob can continue to rotate, under slippage, until the knob and ste ...
