Abstract: The present invention includes bainitic steel doctor blades, bainitic steel coating blades, bainitic steel creping blades and bainitic steel rule die knives used in gravure printing, flexographic printing, paper making, die cutting of materials including paper, plastic, foam, leather, etc. Other uses include printing processes such as pad printing and electrostatic printing. The invention also includes an improved method for producing bainitic steel strip. The present invention is accomplished by using bainitic steel components that exhibit superior straightness and wear properties and are bendable around small radii.

Abstract: Apparatus for automatically leveling the forks of vertically moveable hoist arms. In a typical embodiment, the arms are used on refuse collection vehicles for lifting and dumping detachable containers into the body of the vehicle. The arms are pivotally mounted at one end on the vehicle and the opposite ends of the arms has fork devices for engaging brackets on opposite end walls of the detachable containers. Swinging movement of the arms and of the forks is accomplished by means of hydraulic cylinders or rams. A hydraulic pump supplies fluid under pressure to the arm cylinders for raising the arms. A portion of the fluid is conducted to the fork cylinder by means of a gear or vane type flow divider, so that the rate of extension of the piston in each fork cylinder is at a predetermined ration of the displacement of the arm piston.
