Title: Innovations by Arnold Mendelsohn in Elevator Technology
Introduction
Arnold Mendelsohn is a notable inventor based in Simsbury, CT (US), recognized for his contributions to elevator technology. He holds a total of 4 patents, showcasing his innovative approach to improving elevator systems.
Latest Patents
Mendelsohn's latest patents include advancements in traction elevators with adjustable traction sheave loading. This invention allows elevators operating in hoistways to serve landings at different floor levels in multi-story buildings. The design incorporates a compensation sheave engaged in the lower bight of the rope, which carries most of the weight, providing traction and transmitting tension force effectively. Additionally, the adjustable comp sheave support assembly enables tension adjustment in the rope, facilitating quick releveling of the elevator in response to loading changes.
Another significant patent is the dynamically generated adaptive elevator velocity profile. This innovation combines an open loop, least time profile for acceleration with a precision closed loop, phase plane control for deceleration. The result is a deceleration phase-plane velocity profile that mirrors the acceleration profile, ensuring a smooth transition while maintaining ride quality. This adaptive control allows for the use of smaller drive units without compromising performance, even under challenging conditions.
