    摘要： A uniformly premixed sealant is extruded into a packaging form and allowed to pressure equilibrate prior to freezing. Upon warming the sealant begins to cure. The storage of the preformed sealant formulation under cold conditions arrests the activity of cure catalysts and accelerators mixed therethrough. The sealant is readily extruded into a preform shape containing a lightweight filler. A release film is provided to avoid contact with the sealant preformed in a shape during application to a substrate.

    摘要： A digital controlling system for fiber optic vortex shedding flowmeters which provides a new and improved preamp circuit and a computer for correcting temperature, linearity and hysteresis effects. The controlling system overcomes the inherent non-linearity of the vortex shedding phenomena and also provides two-way communication between a central control unit and the fiber optic vortex shedding flowmeter. The improved preamp circuitry increases the low-end range of fiber optic vortex shedding flowmeters.
