    摘要: A mass sensoring system for monitoring the amount of fluid in a storage tank with an accuracy high enough to determine both the quantity present and the potential loss of fluid at a loss rate of 0.05 gal/hr or at least 0.1 gal/hr. The system utilizes a pressure sensor positioned at the bottom of the tank and in contact with the fluid. This device includes a bellows unit whose displacement is correlated to changes in the mass of fluid in which it is immersed, and a transducer for monitoring the position of the bellows, wherein the interior of the bellows unit is in the same atmosphere as the sensor, and the sensor is in communication with the vapor pressure immediately above the fluid in the tank. The outside of the bellows is subjected to the stored fluid. A multiple-capsule bellows assembly is coupled to an LDVT transducer in a thermal-expansion-cancelling configuration of the invention.

    摘要: A portable handheld electrical power generator for general consumption by household electronic devices is disclosed. The portable handheld power generator provides a magnet reinforcing ring and an armature core of stator lamination stamped with insulation film to provide improved performance and longer lasting operational life. The generator includes a generator casing; a cranking system, a set of cranking gears and an alternator comprised of a magnet-rotor base, a magnet reinforcing ring, a plurality of magnets, induction coils, armature core of stator lamination stamped with insulation film, all in a concentric manner and centered around an alternator drive shaft and housed within the generator casing. When a user manually drives the cranking handle, it causes the gear set to rotate which, in turn, brings about corresponding caming of the induction coils and the armature core, thereby generating electrical power for consumption.
