Abstract: MULTI-FUEL ENGINE CONTROL WITH CANISTER PURGE          Abstract of the Disclosure A fuel control for a vehicle engine using a liquid mixture of two fuels includes a fuel vapor canister open to the fuel tank and canister purge apparatus effective to allow fuel vapors to be drawn from the canister to the engine at a controlled purge rate during engine operation.  The canister purge apparatus is responsive to a fuel composition sensor to vary the purge rate as a function of the fuel composition.  If the two fuels are gasoline and methanol, the canister purge rate is varied, in a predetermined range of fuel temperature, so as to provide a higher purge rate for mixtures of gasoline and methanol, in at least some proportions, than for either gasoline or methanol alone.  The canister purge rate may further be varied in response to fuel temperature.

Title: Relay communication system
Inventor: BERMAN ARNOLD L
IPC: H04B7/216
Filed: 1990-11-05
Abstract: The invention is a relay communications system which uses a single reference frequency signal generator to produce a plurality of precisely frequency synchronized code division multiple access radio frequency signals. A transmitter transmits the synchronized signals to a remote satellite based retransmitter which includes a slave oscillator precisely synchronized to the reference signal generator for down-linking the multiple radio frequency signals to a common radio frequency with all of thedown-linked signals being in precise phase synchronism. The relative phase of the down-linked signals can be preserved or altered and the signals combined and amplified by a high-power amplifier operating in the saturation mode. The output from the high power amplifier is applied to a beamforming network to form an overlapping beam signal comprised of multiple code division multiple access information signals.
