Title: Innovations of John M Brown, Jr.
Introduction
John M Brown, Jr. is a notable inventor based in Westminster, MD (US). He holds three patents that showcase his contributions to the field of engineering and technology. His work has significantly impacted the industries he has been involved in.
Latest Patents
One of his latest patents is for a rotary blow molding machine. This innovative machine features a horizontal main shaft with multiple molds that are spaced around the shaft. The molds are mounted on the shaft by linear bearings, allowing for movement along the shaft. The shaft drive rotates the shaft and molds around the axis, enabling the molds to open and close on a parison. The closed molds are then shifted axially along the main shaft, where the parison is blown. Afterward, the molds return to the eject position, allowing molded containers to be ejected downwardly with the assistance of gravity.
Another significant patent is for a cam-following bridge contact carrier for a current limiting circuit. This circuit breaker includes a stationary contact assembly and a movable contact bridge. A contact carrier is connected to the contact bridge, which biases it toward the closed position. The downward biasing force on the contact bridge is mechanically reduced in response to a preselected amount of opening movement of the contact bridge.
