Patent number: 10718468Abstract: A method and apparatus fueling vehicle with gaseous fuel includes storage vessels, dispensing sub-stations and a controller. The storage tanks or vessels can be at different pressures. The plurality of dispensing sub-stations each include a dispensing hose and a control valve. Each dispensing sub-station is in controllable fluid communication with the storage vessels so that fluid can flow from the storage vessels through the dispensing sub-station to a vehicle tank. A dispensing hose, and a control valve of the dispensing sub-stations are in the fluid flow paths. The controller receives feedback indicative of a filling parameter from the dispensing sub-stations, and provides control signals to the control valves of the first and second dispensing sub-station to implement one or more desired fill schemes.Type: GrantFiled: April 22, 2016Date of Patent: July 21, 2020Assignee: CMD CorporationInventors: Rock J.

Patent number: 10549874Abstract: A pouch machine includes an infeed section, a sealing section, and an outfeed section. The infeed section provides a pouch or laminate to the sealing section, and the outfeed section receives the sealed pouch from the infeed section. The sealing section includes at least one sealer that has a sealing fixture disposed to move in a first direction toward and away from a sealing position. A linear actuator is mounted to provide a controlled motion in a second direction, that is not the first direction. A linkage is connected between the linear actuator and the sealing fixture. The linkage translates the controlled motion of the actuator into controlled motion of the sealer. The linkage preferably multiplies force when the sealer is in the sealing position, and multiplies distance/velocity when the sealer is retracted. The sealing fixture preferably includes a die backing member and a sealing die. The die backing member has at least one clip mounted on it.Type: GrantFiled: October 6, 2015Date of Patent: February 4, 2020Assignee: CMD CorporationInventors: Daniel J. Moran, Peter T. Hunnicutt
