With a total of six patents to his name, Carlton has made significant advancements in the field, particularly with his innovative designs that enhance the functionality and accuracy of pressure measurement devices.
Latest Patents
Among his latest patents are the "Wide Scale Pointer Arc" and the "Pressure Responsive Sending Unit." The Wide Scale Pointer Arc patent describes an indicator gauge that utilizes a motion amplifying mechanism, allowing a diaphragm-type pressure gauge to provide large angular displacements for an indicating pointer. This design ensures maximum readout visibility ranging from approximately 0 degrees to 270 degrees. The mechanism includes a single-piece crankshaft that translates the short range of motion of a diaphragm button to a pivotal gear segment, which can be configured in various shapes for optimal performance.
The Pressure Responsive Sending Unit patent outlines a condition-responsive sending and indicating unit that senses a condition and transmits a signal representative of that condition to a remote indicator. This unit features indicia for local indication of the sensed condition and includes a movable contact associated with a variable resistor, producing a variable signal in response to changes in the sensed condition. Calibration is achieved through adjustments to the movable means and the position of the resistor.
