Abstract: ER FLUID FORCE TRANSMISSION AND CONVERSION DEVICE              WITH MAGNETIC COUPLING                         Abstract An electrorheological fluid torque transmission and conversion system provides for variable control of torque in clutch and brake applications. Communication of mechanical energy between the drive elements is accomplished by magnetic coupling to eliminate the need for a dynamic fluid seal for interface of moving parts to the interior portion of the electrorheological fluid containment chamber. Permanent magnets are associated respectively with each of a first member and a second member which are magnetically coupled through a surface with low magnetic permeability such that the first member and second members rotate in unison. A variety of permanent arrangements may be utilized. Further, the drive element internal to the electrorheological fluid chamber may be both mechanically and electrically decoupled. A floating electrode may be capacitively coupled through the fluid to the power supply. Also provided are inner and outer conductive plates are provided for increased fluid surface contact area. Spacing between the inner and outer plates is determined by the thickness of inner and outer ring members therebetween, which may be easily removed and replaced for simplified assembly and adjustment. Condition responsive control of the electrorheological fluid torque transmission and conversion system is provided by closed-loop feedback of a signal indicative of rotational speed between the drive elements to the control system. The control system may also incorporate internal power generation to provide a self-contained system which does not require an external power source.

Abstract: The preparation of highly densified ceramic bodies by the sintering of certain polysilanes filled with silicon carbide powders, metal-containing sintering aids and, optionally, polysilane curing agents is described.  Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process.  The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities.  One advantage of the present invention is that the green bodies have relatively high strengths and thus can be easily handled and, if desired, machined before being sintered.  The polysilanes useful in this invention must yield a ceramic char which contains free or excess carbon in addition to carbon in the form of silicon carbide upon pyrolysis to elevated temperatures.

Title: Tetrahedral junction waveguide switch
Inventor: STERN RICHARD A
IPC: H01P1/11
Filed: 1989-09-27
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE         A tetrahedral junction waveguide switch is provided having two axially juxtaposed sections of hollow rectangular waveguide which are mutually cross-polarized by being rotated 90 degrees with respect to each other.  A rod of a ferrite material having gyromagnetic properties is axially disposed within the juxtaposed ends of the waveguide sections and is selectively axially magnetized to control transmission of RF electromagnetic wave energy through the sections.  A permanent magnet structure having a unique cladding arrangement which minimizes flux leakage and produces a magnet of high coercive force is employed to produce a unidirectional magnetic bias field along the longitudinal axis of the rod to keep the switch in a low loss transmission state by virtue of Reggia-Spencer effect signal rotation.  A selectively operable helical coil is utilized to produce another axial magnetic field which nullifies the bias magnetic field when it is desired to place the switch in a high loss or cut-off transmission state.
