Abstract: An off-road emergency vehicle includes an operator compartment with an environmentally controlled atmosphere and wireless communication devices. The modified, extended all-terrain vehicle frame supports an enclosed equipment compartment having a top and sides. The equipment compartment is large enough to enclose a full-length stretcher for someone in need of care in an off-road area. The equipment compartment also contains a bench for an emergency technician and storage. The vehicle includes a secondary power source used to supply power to the lighting system and equipment of the equipment compartment.

Abstract: An operating system and choke valve actuator mechanism for a plunger lift gas and oil well having a casing and a tubing string. The actuator mechanism has a manual "low stage" setting for the choke valve so that low velocity gas will flow from the tubing string. The system has a control unit responsive to a pressure differential between casing gas (high) and tubing string gas (low) to move the actuator mechanism to a "high stage" setting for the choke valve so that high velocity gas and oil will flow for the tubing string.
