Abstract: A thermal protector includes a header plate and a metal housing having an open end hermetically welded to an peripheral edge of the header plate. The housing is formed into a generally slender shape so as to be suited for mounting on end turns of a stator winding of a three-phase electric motor. A thermally responsive element includes a shallow curved portion at which the element changes states of curvature with snap action in response to different ambient temperatures. The thermally responsive element has two movable contacts secured to it to be disposed symmetrically about a center of the curved portion so that the movable contacts are engageable with and disengageable from fixed contacts respectively. A push piece is disposed in the housing to exert a pushing force on a normally convex side of the thermally responsive element. The pushing force is adjusted by deforming the outer surface portion of the housing for calibration of the operating temperature. The push piece includes a portion secured to an inner surface of the housing so as to correspond substantially to the deformed outer surface portion of the housing for calibration of the operating temperature.

Abstract: A movable condition-responsive member such as a snap-acting dished metal member is mounted in a condition-responsive device to move between spaced dispositions such as between the original and inverted dished configurations of a dished metal member in response to occurrence of selected pressure, force or temperature conditions. The member is arranged to engage and move the device control elements during such movement to perform control functions. A series of artifacts such as laser-melted portions of the metal materials embodied in the member are provided in the surface of the member, typically after the member is assembled in the control device. Each artifact establishes a local pattern of stresses in the member at variance with a pattern of stresses in the member adjacent to the artifacts, and the artifacts cooperate to precisely determine the condition which results in the snap-acting member movement. The member is intially formed and processed in conventional manner to provide the member with intended initial condition-response properties differing by selected value from the properties ultimately to be established in the member, and is tested to display its actual properties as initially formed. The artifacts are each proportioned to modify the condition-response properties by only a small increment of said value and they are formed in sequence, typically after member assembly in the device, as the response of the device is tested to precisely determine the condition-response properties of the member in the device.
