A method and system (100) for determining and quantifying the resistance to scuff damage of a film (152) adhered to a substrate (150) of a panel (154), is described. The system includes a computer (102), pressure control valves (104) and a test module (10). The test module has an indentor support plate (12) with an indentor (24 or 224), a compression moving plate (14) and an end plate (16). The plates are connected together by rods (18). The indentor support plate and the end plate are mounted at opposite ends of the rods with the compression moving plate mounted therebetween. An actuator (36) having bellows (42) is mounted between the end plate and the compression moving plate. The panel is mounted on a sliding panel support plate (58) which is connected to a load cell (106). In use, the panel support plate and the panel are positioned between the compression moving plate and the indentor support plate so that the indentor is adjacent the film on the substrate. Next, air is provided to the actuator which moves the moving plate toward the indentor support plate and causes the indentor to make contact with the film on the substrate. The panel support plate and the panel are moved down between the plates such that the indentor produces a scuff on the film. The indentation load on the panel is read by the computer from the load cell.

Composite products incorporating a polymer matrix, polymer microspheres, glass microspheres and natural fibers, particularly kenaf are described. The polymer microspheres are 15 to 50 microns in diameter and are smaller that the glass microspheres which are 50 to 200 microns in diameter. The polymer microspheres reduce voids and prevent cracking of the glass microspheres upon compression. The composites have low cost and high strength.

A magnetic flux concentrator trip unit for molded case circuit breakers in the form of a flux concentrator magnet arranged round the load strap at one end of the circuit breaker is positioned in magnetic proximity to an armature. Current transport through the load strap generates attractive magnetic forces to articulate the circuit breaker operating mechanism when the current exceeds a threshold value.

A molded case circuit breaker enclosure and operating components are provided with additional features to enable compliance with a variety of international electrical requirements for sales in the world market. The circuit breaker operating handle is prevented from returning to the OFF position upon contact welding as one example. Another modification includes a reinforcement and rejection pin used with the enclosure case. A further modification includes a shield used with the movable contact arm to prevent the arc gas contaminants from contacting the circuit breaker operating springs.

An electronic trip molded case circuit breaker includes components that are designed for high speed robotic assembly. A unitary trip-to-test button is down-loaded within the circuit breaker housing for automatic alignment with the circuit breaker operating mechanism during the circuit breaker assembly process. The trip-to-test button includes an exhaust gas barrier along with a roller actuator for interacting with the circuit breaker operating mechanism during a test function.

An industrial-rated circuit breaker cover is adapted for optimally receiving an advanced electronic trip unit including a keypad and display unit as well as a basic electronic trip unit providing circuit interruption facility without the keypad and display unit. The load terminals electrically connect the current sensing transformers with the external power circuit and receive the same size lugs that connect the circuit breaker with the electrical power distribution circuits.

A compact molded case circuit breaker with increased ampere rating employs a latch assembly for maintaining the circuit breaker operating mechanism in a closed condition against a pair of powerful operating springs. To increase the mechanical advantage required to move the operating handle against the springs, a retractable handle extender is attached to the handle. For higher-rated circuit applications, a lug cover extension is added to the line end of the breaker to assist in extinguishing the intense arc that occurs during circuit interruption and to protect the line lugs from inter-phasal circuit faults. A visual access slot is arranged next to the circuit breaker handle to ascertain and verify the condition of the circuit breaker contacts.
