Abstract: The invention provides a reluctance generator for an eddy current braking system in a vehicle. The reluctance generator has a field winding and a compensation winding, which induce magnetomotive forces. The magnetomotive force induced by the compensation winding balances the magnetomotive force generated by a rotor in the reluctance generator. The field winding has less inductance.

Abstract: A self-lubricating bearing for use in submersible oil-filled motors is disclosed. The bearing comprises a bearing housing and is fixed against rotation. A bearing sleeve is disposed in the bearing housing. The bearing sleeve is fixed in the bearing housing, and has a slot disposed therethrough. The bearing housing has an inlet and an outlet defined therethrough that intersect the slot in the bearing sleeve. The bearing is disposed about a rotatable shaft in the motor. Rotation of the shaft will cause oil to be drawn in through the inlet so that the shaft and the bearing surface of the bearing sleeve are lubricated. Rotation will also cause oil drawn in through the inlet to be expelled through the outlet back into the motor so that there is a constant circulation of oil through the bearing to provide lubrication.

Abstract: Both an system and method are provided for transferring liquid carbon dioxide from a storage tank pressurized at 300 psi to a truck-transportable tank pressurized at about 110 psi. The system includes an inlet conduit having a hose portion connected between the storage and transportable tanks for conducting a flow of liquid carbon dioxide therebetween, and a vent hose connected to the transportable tank for venting gaseous carbon dioxide. Pressure regulators are connected to the inlet and vent hoses, respectively. In operation, the pressure regulator connected to the inlet conduit reduces the pressure of the flow of liquid carbon dioxide entering the transportable tank from 300 psi to 175 psi, while the pressure regulator connected to the vent conduit maintains a back pressure of 110 psi in the transportable tank while the allowing the venting of gaseous carbon dioxide.
