Abstract: An arc runner assembly for use in a circuit interrupter provides a pair of arc runners that are situated at opposite sides of a stationary contact of the circuit interrupter. If used in a DC application, the arc runner assembly is configured to communicate a positive DC arc along one of the arc runners in a first direction away from the stationary contact and is further configured to communicate a negative DC arc along the other arc runner in another direction away from the stationary contact. The arc runner assembly additionally includes a support that is electrically engaged with a conductor of the circuit interrupter on a surface opposite that on which the stationary contact is disposed. The improved arc runner assembly advantageously facilitates extinction of electrical arc and extinguishes both positive and negative DC arcs in a DC application.

Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. A large variety of patterns may be formed in SMP-integrated fabrics based upon how the shape memory polymer is integrated into the base fabric. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality. By using multiple formulations of SMP on a single piece of fabric, a large combination of material properties may be provided within a single SMP-integrated fabric device.

Abstract: A golf training device used to place the putter square to the golf ball and or target at address. The device consists of a straight back edge roughly the same length as a putter head. An open slot starts from the front going through the center of the device to a point where the ball sets at the same distance from the putter as the back of the device at address. The ball sets into the device at a straight line to the hole or target when placed into the slot of the device. If the golf ball is struck with the putter head parallel to the back of the device, and the slot is straight to the hole or target, the path of the ball to the hole or target will be straight. This improves grip and stance at address giving a true path to the hole or target as well as topspin from missing the device for a better roll.
