    摘要： An assembly for sensing the dielectric constant of liquids, and for detecting contamination, includes a central ceramic chip with a sensing capacitor formed on one end thereof and a signal processing circuit on the other end thereof. The capacitor is formed of two sets of closely spaced conductive lines or pathways with one set being grounded and the other set providing the variable output from the capacitor to the signal processing circuit.

    摘要： A new blading system for controlling the structural vibrations in axial-flow compressors, turbines, or fans, as in aircraft engines and like turbomachines including a stator disc and a rotor disc is presented. The rotor disc defines several radial hubs that retain the rotor blading systems. Each blading system includes a blade formed of an airfoil, and a root attachment which is dimensioned to fit within, and to engage a corresponding hub. Viscoelastic dampers are selectively applied to the outer surfaces of the root attachment on which compressive or shear forces are likely to develop, intermediate the root attachment and the hub, for compression therebetween upon rotation of the rotor disc, in order to dampen structural vibrations. One advantage presented by the viscoelastic dampers lies in its simplicity, efficiency, cost effectiveness, and its ability to be retrofitted into existing turbomachines with minor surface treatment of the root attachments. Furthermore, since the dampers are not exposed to the inflowing airstream, they do not affect the aerodynamic performance of the turbomachine. Another feature of the damping system is that it provides a significant source of damping to minimize destructive structural vibrations, thereby increasing the durability of the turbomachine, and reducing acoustic noise accompanying high amplitude vibrations.

    摘要： Described herein is the sensor assembly and method for rapidly obtaining accurate readings of a variable. The sensor assembly comprises a plurality of sensors which are connected to a microcontroller that processes the signals of the individual transducers to the microcontroller. The microcontroller contains software that maximizes the refresh rate and/or minimizes the time it takes to process the outputs of each of the transducers. The microcontroller that is coupled to the sensor assembly selectively measures the outputs of each transducer so as to speed up the refresh rate of the sensor.
