Patent CA-2214356-A1 (CA)
Title: Coriolis effect mass flowmeter using concentric rotors
Inventor: LOVING ROGER SCOTT
IPC: G01F1/84
Filed: 1996-03-12
Abstract: A Coriolis flowmeter having an outer rotor (307) positioned within a housing (301) and having a recess coaxial (341) with a center axis of rotation. A  Coriolis rotor (314) is positioned in the recess of the outer rotor and has a center of rotation coaxial with the center axis of rotation. The Coriolis rotor has a plurality of holes (312), each of which extends from the outer periphery of said Coriolis rotor to a center recess of said Coriolis rotor.  The outer rotor has a plurality of holes (309), each of which extends from the outer periphery of the outer rotor to the recess of said outer rotor with at least some of said holes in said outer rotor being aligned with a corresponding one of said plurality of said holes in said Coriolis rotor. A  material inlet (302) extends fluid through holes of both the outer rotor and the Coriolis rotor to a material outlet (304) of the flowmeter. Both rotors rotate about the center axis of rotation when material is received and passes through the holes of the rotors. Coriolis forces generated by the material flowing through the rotor holes and the concurrent rotation of both rotors cause the Coriolis rotor to assume an angular offset from the outer rotor about the center axis of rotation. Sensing coils (323, 324) and magnets (316, 344) generate output signals indicative of the magnitude of the angular offset of the Coriolis rotor and the mass flow rate of the flowing material.

IPC: H02J7/02
Filed: 1998-10-09
Abstract: Variation of the charged amount among battery blocks composing a battery assembly is detected. By subtracting the detected value of the variation from the width between the upper limit value and the lower limit value of the charged amount, the movable range of the charged amount is found. The position of the present charged amount is detected as the state of charge. For example, it is arranged that both ends of the movable range are 0% and 100%, and that the movable range is the full scale. Then, the position of the charged amount on this scale is specified by the ratio %. The detection of the state of charge in which the variation in charged amount and the change of the movable range are considered, is performed, and on the basis of this state of charge, a preferable charge and discharge control is performed.
