Latest Patents

Among Boldt's latest patents is a groundbreaking controller designed for two modes of braking induction motors. This innovative controller integrates advanced functionalities, such as delayed resetting circuits connected to timing circuits for enabling delayed firing. Additionally, it features circuits for inverting the polarity of error signals to accommodate regenerative and reverse-plug braking. The design employs sequence switching circuits which ensure that full acceleration or deceleration is achieved before transitioning to a newly selected mode. Notably, the controller also incorporates a curve-shaping circuit succeeding the ramp generator, which smoothly adjusts the slope at the ends of a selected ramp segment for seamless starting and stopping of elevators. Furthermore, a brake control circuit synchronizes the disconnection of the motor with the application of mechanical brakes, ensuring a smooth operational transition.

Another of his recent patents addresses stroke control responsive to the impact of hydraulic hammers. This invention employs a pickup connected to the system of sheaves on the hydraulic hammer, providing a signal proportional to the hammer weight's velocity. By utilizing a differentiating circuit, the signal input serves as a timer starter, effectively managing the lift and drop of the hammer weight based on its acceleration state. The timer not only dictates the lifting of the hammer weight to a predetermined height without delay but also determines the dropping action after a specified timing period, enhancing the hammer's operational efficacy.
