Abstract: A piston is moveably arranged in a cylindrical bore of a housing and the piston rod extends through one end of the housing for connection to a unit to be controlled. A very high variable control rate of the piston is made possible by a control slide valve formed as a hollow cylinder that is moveable within a coaxial bore of the piston rod. The hollow, cylindrical, control slide valve contains a plurality of apertures that cooperate with ports formed in the piston rod that extends on either side of the piston. A chamber formed on one side of the piston is connected to a source of pressurized fluid and a chamber at the other side of the piston is connected to a return for such pressurized fluid. A control rod is connected to the control slide valve for moving same within the coaxial bore of the piston rod and by specially forming the guiding or leading edges of the apertures formed in the control slide valve, high variable control rates are possible.

Abstract: A system for the control of a fluid flow control valve which controls the supply of fluid to an actuator to control the movement of a component such as a tractor implement hitch in response to a selected operating parameter such as hitch position or draft force. The system enables the desired value of the selected parameter to be set and this desired value is compared with the actual sensed value of the parameter to provide a parameter error signal. A start-up control function is provided to improve the initial speed of response of the system. The start-up control function is arranged on each detection of a parameter error signal to apply a start-up signal to the valve to initiate movement of the component and, if no movement results, to increase the start-up signal until movement of the component is detected whereupon the increase in the start-up signal is stopped and the magnitude of the signal applied to the valve is dependent on the parameter error signal so as to tend to reduce the error signal to zero.

Abstract: An obturating band of the despun variety is manufactured within the channel of a projectile assembly. A split ring polymer pre-band is clamped around the band seat of the projectile assembly and the free ends are welded together to form a continuous ring around the diameter of the projectile assembly within the encircling channel. One free end includes a male connector and the other free end includes an undersized female receptacle. Upon exposure to ultrasonic energy, the free ends are welded together at a scarf joint.

The joining surfaces are positioned on indented sections of the free ends such that the resulting obturating band does not bulge at the joint. The obturating band is constructed to slip against the band seat and, therefore, is allowed to rotate at a rate independent of the underlying projectile.
