A magnetorheological fluid damping system includes a hydraulic cylinder, a piston head, a piston rod, and a porous valve. The hydraulic cylinder configured for disposing magnetorheological fluid therein. The piston head is disposed within the hydraulic cylinder and has first and second sides defining first and second chambers within the hydraulic cylinder. The piston head is configured to be in sliding engagement with the hydraulic cylinder. The piston rod is connected to the piston head. The porous valve includes a magnetorheological fluid pathway, has first and second fluid connections, and is configured to dampen the flow of the magnetorheological fluid between the first and second fluid connections in accordance with a magnetic field. The first fluid connection is fluidly connected to the first chamber and the second fluid connection is fluidly connected to the second chamber. The magnetorheological fluid pathway partially directs magnetorheological fluid flow through a porous media.

A router bit with a position stop is disclosed. The router bit includes a body with a collar extending outwardly from it and a shaft extending outwardly from the collar. At least one cutter blade is mounted to the body and the cutter blade may be used to cut a profile into a workpiece. The collar has a first diameter, the shaft has a second diameter and the first diameter is larger than the second diameter. The collar has a face formed a spaced distance or height from the transition point between the collar and the body. The face rests against the upper surface of a chuck when the shaft is secured in the chuck. This allows the body and hence the cutter blades to be held a predetermined distance above the upper surface of the chuck. A second router bit may be provided to cut a complimentary second profile in a second workpiece. The second router bit includes a collar that positions the cutter blade of the second router bit in the chuck at a complimentary height with respect to the cutter blade of the first router bit. When the first and second workpieces are brought together, the profiles of the two workpieces are able to interlock in such a way that the workpieces are both functionally and aesthetically aligned with each other.

A method to process an incentive includes, at a commerce server, receiving an incentive identification code that identifies an incentive amount to be used for at least a partial payment of a transaction. A determination is made at the commerce server whether the incentive is valid. If the incentive is determined to the valid, incentive information is communicated to a payment processor server from the commerce server, the incentive information including an authorization that authorizes the payment processor server to transfer the amount as the partial payment for the transaction.

A road cutting apparatus is detachable and connectable to a self-propelled front end loading machine. The cutting apparatus includes a rigid frame structure having a connecting section for attaching the frame structure to the front end loading machine and a planar mounting section. An engine including a power take off (PTO) is mounted to a top surface of the mounting section for driving the circular cutting apparatus, and a belt drive is attached to the PTO. The belt drive includes a driving pulley and a following pulley, and a belt disposed between the driving pulley and following pulley provides for transfer of torque therebetween. A driven shaft with a first end and a second end is mounted to the mounting section and attached to the following pulley at its first end, and a retainer blade is connected to the second end for coupling to a circular cutting blade. A cutting assembly is mounted on the mounting section which includes the circular cutting blade and a cooling system for cooling the cutting blade. The circular cutting blade rotates counterclockwise relative a forward cutting direction of the front end loader when the PTO is engaged and powered by the engine.

A single part zipper pull comprising of 2 rotatable halves secured together on a pin. On one end of the zipper pull is a handle by which fingers can grasp the pull. On the other end of the zipper pull are clasps to latch to the zipper slider. The complete clasp is made up of the 2 J hooks, one on each half. The handle is made complete by rotating the two halves of the zipper pull together. In the open position, the J hooks have a gap by which to engage the zipper slider crown. In the closed position, the clasps come together making a complete loop thereby securing to the zipper slider crown. Once the zipper pull tab is closed, a latch and receiver engage to prevent the 2 halves from rotating to an open position.
