摘要: A high speed, high voltage, square wave voltage, single slot per pole per phase, two phase, saturated rotary field AC generator having a rotary armature exciter, is comprised of noncompressible, rigid rotary coils utilizing oxided metal conductors having coolant fluid flowing therethrough, at least one surface of every electrical current conductor in the generator being in contact with flowing coolant fluid. The rotary structure is provided with a complete peripheral structural wrapping to oppose the centrifugal force generated in the coils due to high velocity. Rotary diodes between an exciter armature and the main generator, rotary field, a single static DC input and static AC output, and magnetic coupling comprising the sole energy coupling between the stator and the rotor, eliminate the need for slip rings or other electrical conduction through relatively moving parts. One embodiment utilizes turbine-like annular entrance of centrifugal pumping for coolant fluid in the rotary coils; in this embodiment, rotating diodes are mounted on coaxial shaft-like conductors. Another embodiment uses hollow radial conductors to carry coolant fluid, as well as electrical current, to the coils; in this embodiment the radial fluidcontaining electrical conductors are terminated in annular junctions connected to annular diode housings by longitudinal or axial conductors.

摘要: A vibrating cylinder pressure transducer has magnetic drive and pick up coils disposed in a non-magnetic cylindrical wall outside of the vibrating cylinder, all wires leading to and from the magnets being outside of the pressure chambers all together, whereby the interior of the vibrating cylinder is readily provided with a hermetic seal so as to provide an annular pressure chamber outside the vibrating cylinder, the inside of the vibrating cylinder being evacuated and the annular chamber being connected to a fluid source, the absolute pressure of which is to be measured. In one embodiment, a three lobe (six node) vibration mode is rendered possible by providing electromagnets (either the drive pair or the sense pair) at an angle of 120* with respect to each other, the other pair being operated out of phase, diametrically opposite each other and along the bisector of the first pair.
