Title: Innovations of David H Hitt
Introduction
David H Hitt is a notable inventor based in Rockford, IL (US), recognized for his contributions to technology with a total of three patents. His work primarily focuses on advancements in torque measurement and cooling systems for generators.
Latest Patents
One of Hitt's latest patents is a torque measuring apparatus designed to provide high-speed torque measurements. This apparatus features first and second coaxial members interconnected by an elastic coupling, allowing for relative angular displacement proportional to the torque load applied. The design includes concentric apertures that overlap in response to this displacement, enabling a light source to transmit light through the apertures, with intensity correlating to the overlap amount.
Another significant patent is a stator end winding cooling arrangement for variable speed generators. This invention includes a fluid sprayer within the rotor that delivers cooling fluid to the stator windings. The design ensures that the fluid flow rate remains constant, regardless of rotor speed, preventing over-spraying at high speeds. The preferred embodiment utilizes oil as the cooling fluid, which passes through a fixed metering orifice to maintain a maximum flow rate.
