Patent CA-2086170-A1 (CA)
Inventor: WEIMER MATTHEW M
IPC: F01D11/22
Filed: 1992-12-23
Abstract: A turbomachine including a case, a rotor, a plurality of rotor blades on the rotor each having a blade tip, a shroud around the rotor blade tips, and means mounting the rotor on the case for rotation about a centerline of the case and for bodily shiftable movement in the direction of the centerline.  The rotor blade tips and an inside wall of the shroud flare radially outward in the direction of the centerline so that when the rotor moves in the direction of the centerline toward the shroud a clearance gap between the blade tips and the inner wall of the shroud decreases and vice versa.  An electromagnetic actuator on the case magnetically attracts a thrust plate on the rotor against a net dynamic force on the rotor.  A control system of the actuator controls the magnetic attraction of the actuator in response to signals from a position sensor measuring the actual magnitude of the clearance gap to maintain the actual clearance gap at a predetermined magnitude.

Abstract: This invention discloses an antenna element (12) or  an  array  of  antenna  elements  (52)  for  use  in multifunctional systems which exhibits wide bandwidth, small size, polarization diversity and conformality.  In one preferred embodiment, an array of circular conductive patches (56,58) are formed on a dielectric substrate (54) in which adjacent patches are formed on opposite sides of the substrate  (54).   Each of the opposite conducting patches  (56,58) are configured to form a dual  flared slotline such that an electric field created between the two conductive patches (56,58) will exhibit a wide range of impedance matching to free space. By exciting the conductive  patches  (56,58),  radiating  electromagnetic waves  having  a  polarization  with  respect  to  the orientation of the slotlines is produced.   By this,  a single array of antenna elements (52) can be used in a multifunctional system.

Inventor: FEINER ALEXANDER
IPC: H04M3/56
Filed: 1993-11-10
Abstract: Distortion and instability due to echoes in conference communications is reduced through the use of an echo canceller disposed in a conference bridging circuit. This circuit includes a signal combiner which receives information signals from each of the parties in the conference communications and provides an outputsignal which is a combination of the received information signals and an echo compensation signal. The echo canceller provides this echo compensation signal in response to the combiner output signal. Advantageously, the echo canceller can be fixed or adaptive. In the latter case, the adaptation can be in response to the received information signals or to training sequences.

Filed: 1994-07-13
Abstract: ABSTRACT OF THE DISCLOSURE       A facsimile interface unit, which encodes signals from  a  facsimile  terminal  for  transmission  by satellite, can only encode signals which conform to the Group 3 standard.  The interface unit intercepts signals which identify non-standard features supported by the terminal and replaces them by a modified signal of the same format which does not identify any non-standard  features.     Another  facsimile  terminal receiving  the  modified  signal  is  prevented  from enabling any non-standard features and signals to the first facsimile terminal that the Group 3 standard is to be followed.   Therefore, the facsimile interface unit is able to encode and decode signals successfully during the subsequent transmission.
