Title: Method for regenerating mixed ion-exchange resin
Inventor: USUI SHINICHI
IPC: C02F1/42
Filed: 1984-05-22
Abstract: PURPOSE:To lower the concn. of a regenerant which is leaked while treating in a desalting process by regenerating a cation-exchange resin wherein the exchange performance has been diminished with hydrochloric acid and also passing caustic soda soln. through anion-exchange resin after passing sulfuric acid soln. through the resin. CONSTITUTION:After the passing of a regenerant soln. has been finished, the resin incorporated in both regenerating towers is washed and resin (a) and resin (b) are transferred into a resin storage tank 4, mixed by air and stored till these are supplied to the next desalting process. Further, resin (c) and resin (d) are said to be travel resin, used to make the separation of cation-exchange resin and anion- exchange resin excellent and unused for the desalting process. The travel resin is returned to a cation-exchange resin regenerating tower 2 at the last of the regenerating process and at the time of next regenerating process it is supplied to the regenerating process together with the resin which is transferred to the regenerating tower 2 after finishing the desalting process.

Title: Fuel feed amount control device for engine
Inventor: OMURA FUSAJI
IPC: F02D41/22
Filed: 1989-04-21
Abstract: PURPOSE:To prevent the increase of the temperature of exhaust gas as worsening of fuel consumption is suppressed by a method wherein the increase of fuel fed to an engine is not started before a rotation speed gets to an increase starting value at which the rotation speed of an engine is transferred to the low rotation side with the increase in an ignition timing delay amount. CONSTITUTION:The running state of an engine M1 is detected by a running state detecting means M2. Knocking of the engine M1 is decided by a knocking deciding means M3. Further, according to knocking, an ignition timing delay amount is calculated by a delay amount calculating means M4. When a running state enters a fuel increase region for preventing the increase of a given exhaust gas temperature, a fuel increase correction value responding to an ignition timing delay amount is calculated to increase an amount of fuel fed to the engine M1 by means of a fuel increase means M5. In this case, the M5 is mounted to an increase starting part M6 which does not start the increase of fuel, fed to the engine M1, before a rotation speed is transferred to an increase starting value at which the rotation speed of the engine M1 is transferred to the low rotation side with the increase in an ignition timing delay amount.
