Abstract: A hydraulic rate control system for maintaining a selected application rate at varying ground speeds. The application rate is selected through an operator control which permits the operator to dial in the spray tip size, the width of the spray pattern per tip and the desired spray rate in gallons per acre, and this application rate can be changed on the go. A ground-driven hydraulic oil pump directs its entire flow through a variable orifice, adjusted through manipulation of the operator control, and the oil pressure acts against a balance valve which maintains the pressure of the chemical to be sprayed equal to the oil pressure at the variable orifice. As the ground speed increases or decreases, the oil pressure and thus the chemical pressure increases or decreases accordingly to maintain the selected application rate.

Abstract: A continuous paper web-moving mechanism has a supply roll on which the paper is wound and pulled from the supply roll by a drive roll that engages the paper on its surface by a pressure exerted against the paper at that point. In this preferred embodiment the pressure is exerted by a thermal printhead resiliently mounted to force the paper against the drive roll. A leaf spring is mounted at one end of the drive roll, bearing against the edge of the wound paper, providing a friction drag on the drive roll. Also, the drive roll is kept in a fixed lateral position by the force of the leaf spring, aiding in aligning the paper. The tension between the supply roll and the drive roll is such that the paper is stiffened, providing a contact with the surface of the drive roller in a tangential line.

And before the torsion bar is broken, the stopper means operates to stop the rotation of the reel. Therefore, even if a large tension force is applied to the seat belt, the torsion bar is not broken due to the twisting thereof.
