Abstract: A truck having a material spreader and a control mechanism to regulate the velocity of materials ejected from the material spreader. The material spreader includes a material guider to guide the trajectory of substantially all the materials in a direction substantially opposite the direction of forward movement of the truck. The control mechanism includes a velocity sensor adapted to detect the velocity of the truck and to send a signal indicative of the truck velocity to a velocity controller. The velocity controller sends a signal to the material spreader which is dependent on the truck velocity to control the velocity of the materials ejected from the material spreader. The material spreader is mounted to the truck to allow the material spreader to be moved between a non-operational and operational position. The material spreader is also mounted to allow for lateral and/or upward movement upon encountering a predetermined force.

Abstract: A corrosion-resistant coated copper metal coated with an alloy of tin wherein the tin content constitutes a majority of the alloy. The tin alloy may also include one or more metal additives to improve the coating process and/or to alter the properties of the tin alloy. A metal layer may be applied to the surface of the copper metal prior to applying the tin alloy. The copper material may be pre-treated prior to coating to remove surface oxides. The coating of the tin alloy involves heat to thereby form a heat created intermetallic layer. The coated copper metal can be subsequently treated with a passivation solution to remove the coated tin alloy and expose the intermetallic layer. The intermetallic layer includes copper and tin and exhibits excellent corrosion resistant properties.
