Patent number: 5487346Abstract: A fluid injecting system for injecting fluid into soil is disclosed, the system comprising a tank for receiving and from which is discharged the fluid, mixing apparatus in the tank for mixing the fluid, a transfer pump in fluid communication with the mixing tank, a high pressure pump, the transfer pump in fluid communication with the high pressure pump for pumping fluid from the mixing tank to the high pressure pump, sequencing pumping apparatus for providing sequential charges of fluid to a nozzle apparatus, and nozzle apparatus with at least one nozzle through which fluid is injected into the soil, the sequencing pumping apparatus in fluid communication with the nozzle apparatus. In one aspect an accumulator accumulates a charge of fluid which is supplied to the nozzle apparatus. In one aspect the sequencing pumping apparatus includes a pneumatically controlled sequencing control valve which responds to precise pressure changes to control the duration of fluid pulses.Type: GrantFiled: January 10, 1994Date of Patent: January 30, 1996Inventor: Donald K.

Patent number: 5323309Abstract: An auxiliary resolver position tracking (RPT) system for an industrial robot includes a resolver excitation and monitoring system which is powered by an uninterruptable power supply which includes a battery. The RPT system generates trapezoidal excitation pulses for the resolvers in the robot when no external excitation signal is applied, for example when the robot is shut down. Since there is relatively little motion to be detected in these instances, the RPT system switches between a slow position sampling rate, when no motion is detected, and a fast sampling rate when motion is detected. When operating on battery power, the RPT only switches to the fast sampling rate when motion is detected. To ensure that no motion data is lost when the system switches back to the slow sampling rate, the high sampling rate is maintained for a time sufficient to capture any residual motion of the robot.Type: GrantFiled: January 30, 1992Date of Patent: June 21, 1994Assignees: Siemens Industrial Automation, Inc., Comau S.p.A.Inventors: Donald K. Taylor, Richard J. Maczka, Carl H. Russell, III

Patent number: 4559970Abstract: An improved pilot control relay valve is disclosed to monitor pressure conditions in a pressurized system and to cause the system to shut down in response to detection of operating pressures excessive of an acceptable pressure range. Accurate monitoring is provided for by dual-piston action, with one of the pistons actuating a visual indicator mounted on the slide valve of the control relay valve, and with the second piston coaxially mounted within the first piston.Type: GrantFiled: November 16, 1983Date of Patent: December 24, 1985Assignee: C.S.E.
