Patent CA-2228757-A1 (CA)
Inventor: HAEFNER PAUL A
IPC: A61N1/37
Filed: 1996-08-12
Abstract: A system and method automatically adjusts a sensing threshold in a cardioverter/defibrillator which receives electrical activity of the heart and delivers shock pulses in response thereto. An amplifier amplifies the electrical activity according to a variable gain. A detection circuit detects depolarizations in the amplified electrical activity and provides a detect signal representing a cardiac event indicative of a depolarization when the amplified electrical activity exceeds a variable sensing threshold. Slow gain control circuitry adjusts the variable gain in discrete steps based on stored peak history information representing peak values of the amplified electrical activity. Template generation circuitry responds quickly to set the variable sensing threshold to a level proportional to a peak valve of the amplitude of the amplified electrical activity and then decreases the variable sensing threshold from the level in discrete steps until the variable sensing threshold is at a low threshold value.

Title: Method of manufacturing high purity calcium carbonate
Inventor: HUEGE FRED R
IPC: C01F11/18
Filed: 1996-01-30
Abstract: Flue gases exhausted from a lime kiln (10) containing lime kiln dust are treated to produce a high purity calcium carbonate precipitate. This is accomplished by passing the flue gases from the lime kiln (10) through a kiln dust separator (12) so that lime kiln dust containing calcium oxide is removed from the remaining flue gas (15). The lime kiln dust is mixed with water so that an aqueous suspension of the lime kiln dust is formed. Quicklime or calcium oxide in the lime kiln dust is thus hydrated to form calcium hydroxide. The solids within the suspension are then allowed to settle in settling tank (14) so that a clear, saturated solution of calcium hydroxide having a pH of about 12.4 is formed. This solution is then contacted with carbon dioxide gas in reaction tank (16) so that the calcium hydroxide reacts to form a high purity calcium carbonate precipitate. This high purity calcium carbonate precipitate is then allowed to settle from supernatant water of the solution in thickener tank (20). The high purity calcium carbonate is separated from the supernatant water, while the supernatant water is recycled through conduit (24) and used as the water mixed with the lime kiln dust to form the aqueous suspension.

Patent CA-2247168-A1 (CA)
Title: Lock-up control device
Inventor: SAITO YOSHIHARU
IPC: F16H59/14
Filed: 1998-09-15
Abstract: A lock-up control device is provided to control engaging force of a lock-up clutch, which shares engine output with a torque converter to transmit it toward an input shaft of a transmission. Herein, input shaft torque is estimated based on engine speed and engine intake negative pressure, while engine torque is estimated based on engine speed and throttle opening. A weight coefficient is produced based on an amount of variations of the engine torque when the amount of variations is greater than a prescribed value. Then, weighted mean engine torque is calculated by the input shaft torque and engine torque in accordance with the weight coefficient. Thus, the lock-up control device controls the lock-up clutch based on the weighted mean engine torque in such a way that the engaging force of the lock-up clutch is increased in response to the rise timing of the weighted mean engine torque. For example, the weight coefficient is determined in such a way that the engine torque is given high distributed weight in the weighted mean engine torque as compared with the input shaft torque. Thus, it is possible to increase the engaging force of the lock-up clutch promptly in response to the rise mode of the real engine torque, by which it is possible to avoid occurrence of control delay in control of the lock-up clutch.
