Abstract: Disclosed are weld electrode plugs with polymeric inserts for loss-of-cooling detection, methods for making or for using such weld electrode plugs, and electric welding systems equipped with loss-of-cooling detection plugs. A disclosed loss-of-cooling detection assembly includes a plug that attaches to the weld shank of a welding system such that the plug fluidly couples to a coolant bore within the shank. The plug includes a plug body with a clearance hole extending therethrough. An insert detachably mounts to the plug such that the insert fluidly seals the clearance hole. This insert is fabricated from a polymeric material, such as a shape memory polymer, that alters a physical property, such as shape/size, of the insert responsive to changes in temperature and/or pressure of coolant fluid in the shank's bore. When this physical property is altered, the insert unseals the clearance hole causing a detectable leak of fluid from the shank.

Abstract: A valve assembly includes a body having a longitudinal axis and defining a cavity therein. A shuttle valve is arranged within the cavity. The shuttle valve has a first surface and a second, opposing surface. An actuator element is adjacent the first surface of the shuttle valve and configured for translating the shuttle valve along the longitudinal axis between a first position and a second position. The actuator element is formed from a shape memory alloy that is transitionable between a martensite crystallographic phase and an austenite crystallographic phase in response to a thermal activation signal to thereby translate the shuttle valve between the first position and the second position. Furthermore, a resilient member is adjacent the second surface of the shuttle valve. The resilient member is configured to oppose the movement of the shuttle valve moving from the first position to the second position.

Abstract: A thermal bypass valve includes a housing defining a bore along a longitudinal axis and having two inlet ports and two outlet ports; a cap disposed within the bore; a shuttle disposed within the bore and reversibly translatable towards and away from the cap along the longitudinal axis between a first fill position, a cooling position, and a bypass position; and an actuator configured for translating the shuttle along the longitudinal axis between the cooling position and the bypass position. The actuator is formed from a shape memory alloy and is transitionable between a first state and a second state in response to a temperature of the fluid.

Abstract: Malfunction or failure of mechanical, electrical, and electro-mechanical equipment, for example, equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by closing an externally-powered circuit to enable or provide a suitable alarm signal. Additionally, the actuator may close a second circuit connected to a machine controller to alert the machine controller to take some pre-programmed action. Selected actuators are based on shape memory alloys (SMA) adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

Abstract: A resettable sensor assembly includes a housing having a longitudinal axis and defining a cavity therein. The assembly includes a divider disposed within the cavity and in contact with the housing, at least one electrical contact disposed within the cavity and extending through the divider, and a pin reversibly translatable within the cavity along the axis. The assembly includes at least one actuator element disposed within the cavity and abutting the housing. The element is configured for translating the pin along the axis between a first position wherein the pin contacts the electrical contact and a second position wherein the pin is spaced apart from the electrical contact. The actuator element is formed from a shape memory alloy that is transitionable between an austenite crystallographic phase and a martensite crystallographic phase in response to a thermal activation signal to thereby translate the pin between the first and second positions.

Abstract: A method of joining wire includes preparing a first discrete region of a first wire at a first end of the first wire. The prepared first discrete region is welded to a component to form a joint such that material of the prepared first discrete region at least partially thickens the joint. The component is one of a second end of the first wire, an end of a second wire, or a non-wire component. The joint may be heat treated according to a three-stage heat treatment process. Mechanical stress may be induced in the joint during the heat treatment so that the joint is subjected to thermo-mechanical processing.

CPC classification number: G01N27/041
Abstract: A sensor system includes a housing defining a cavity, an actuator formed from an alloy transitionable between first and second states, a plunger attached to the actuator, and a resilient member configured for translating the plunger within the cavity. The plunger is not translatable during a first condition in which a coating of debris is disposed on the housing as the alloy transitions between the first and second states to define a first stress on the actuator. The plunger is translatable during a second condition in which the housing is substantially free from the coating as the alloy transitions to define a second stress on the actuator that is less than the first stress. The alloy transitions from the first to the second state at a first transformation temperature during the first condition, and at a second transformation temperature that is less than the first temperature during the second condition.
