Title: Series compensator inserting real and reactive impedance into electric power system for damping power oscillations
Inventor: GYUGYI LASZLO
IPC: G05F1/70
Filed: 1995-12-14
Granted: 1998-10-15
Abstract: A series compensator for damping power oscillations in an electric power transmission system includes a switching power converter which injects a voltage into the transmission line having a phase angle relative to transmission line current which is controlled to provide reactive compensation and to inject virtual real impedance into the line. The switching power converter is a dc to ac converter which is capable of injecting virtual real impedance into the transmission line by virtue of the fact that it has a power exchange device connected to its dc terminals. Where the power exchange device is a resistor, the switching power converter is capable of absorbing real power during surges in power on the line. Alternatively, the power exchange device is a storage device such as a battery bank or a super conducting magnet, in which case the switching power converter can provide both virtual positive and negative real impedance.

Title: Improved heating of fluidized bed furnace
Inventor: DALTON ROGER
IPC: C21D9/567
Filed: 1986-08-06
Granted: 1990-05-03
Abstract: A fluidized bed for treating of product at high temperatures (1100°C to 1300°C) is possible, while overcoming problems such as slow start up times and contamination due to combustion gas. The fluidized bed uses an inert gas introduced to the bed to cause fluidization of refractory particles. Exposed surfaces or boundary layer of the bed are heated by infrared radiation produced exterior to the bed and absorbed by exposed particles of the bed. The thermal characteristics of the bed insure rapid dissipation of the absorbed energy. Electrically powered lamps produce the radiation and preferrably are high intensity shortwave infrared radiation lamps. The lamps remain out of direct contact with the bed preferrably separated by a quartz wall or screen.

Title: Method for producing feedstocks of high quality lube base oil from unconverted oil of fuels hydrocracker operating in recycle mode
Inventor: LEE YUN KIL
IPC: C10G69/02
Filed: 1994-05-16
Granted: 1998-01-29
Abstract: A process is disclosed for producing feedstocks for manufacturing high quality lube base oil utilizing unconverted oil, which is produced from a fuels hydrocracker unit. The first step of the process is the distillation of an atmospheric residue under vacuum in a first vacuum distillation unit to produce a vacuum gas oil. The vacuum gas oil is then hydrotreated in a first reaction unit to remove impurities and produce a treated vacuum gas oil. The treated vacuum gas oil is then subjected to hydrocracking in a second reaction unit to yield light hydrocarbons. The light hydrocarbons are then subjected to a series of fractional distillations to separate light oil products and an unconverted oil. All or a fraction of the unconverted oil is fed to a second vacuum distillation unit to produce feedstocks of high quality lube base oil and a remaining portion. The remaining portion and, optionally, a fraction of the unconverted oil is recycled from the second vacuum distillation unit to the second reaction unit.
