Title: A process for the continuous preparation of aqueous formaldehyde solutions
Inventor: EEK-VANCELLS LLUIS
IPC: C07C47/04
Filed: 1995-11-07
Abstract: The process uses a supply column (3) and additional heat exchangers (10, 11, 13) associated with absorption columns (8). Air and methanol from outside and a subcurrent of methanol, originating from a cold methanol current exiting from the supply column (3), are fed to the supply column (3).

Patent CA-2163288-A1 (CA)
Title: Engine demand fuel delivery system
Inventor: LEARMAN WILLIAM L
IPC: F02D41/30
Filed: 1995-11-20
Abstract: A fuel delivery system and method for providing fuel to a fuel injected engine using an engine control unit  (ECU)  to determine engine  fuel  demand and adjust  fuel  pump  operation accordingly to supply at least as much fuel as demanded by the engine. The ECU determines a fuel pump control signal based upon fuel demand and applies the signal to a fuel pump driver that controllably drives the pump in response to the control signal.          The ECU determines fuel demand by monitoring engine operation and calculates a control signal that controls the duration of time the fuel injector stays open during an upcoming intake stroke of engine operation.  The pump control signal  is proportional to engine fuel demand multiplied by a constant that ensures more fuel will be available for delivery to the injector than demanded by the engine. Engine fuel demand is proportional to the duration of time the injector will stay open multiplied by the engine speed.          Preferably, if the calculated pump signal is less than a minimum that would cause the pump to operate below a desired minimum duty cycle,  the  control  signal  is  set  at  the  minimum  to  ensure sufficient excess  fuel  will  be  available  to  meet  any  sharp increases in demand. If the calculated signal is greater than the maximum pump duty cycle, the signal is set at the maximum to avoid damaging the pump. If the calculated signal is between the minimum and maximum limits, the control signal is set to the calculated value.
