Latest Patents

Richard L Thomas holds a patent for an "Elevator system monitoring cold oil." This invention involves a hydraulic elevator system designed to monitor a cold oil thermostat mounted on a hydraulic oil reservoir. The system prewarms the oil prior to passenger service by recirculating it through a pumping path that bypasses the hydraulic jack. A control circuit, including a microprocessor, manages all car and corridor functions. It is photo-coupled to the thermostat for input signals that interact with a program module in random access memory. This module runs in sequence, providing a minimum timer phase for pump motor energization, ensuring the oil reaches the standard minimum operating temperature before activating a maximum timer phase. This innovative design prevents overtemperature issues, protecting the pump motor windings from damage.
