Granted: 1992-09-22
Abstract: LIGHTWEIGHT TRANSFER REFERENCING AND MOORING SYSTEM                 ABSTRACT OF THE DISCLOSURE      An  offshore  fluid  transfer system is described for  transferring fluid between an underwater pipe and a dynamically  positioned vessel at the sea surface, which is  relatively  lightweight  and economical.  The system includes  a  riser  having  an upper end attached to the vessel  and  a  lower  end  having a chain table held by chains  extending  in  catenary  curves to the sea floor and  weighted  by  a  weight hanging by the chain table.          The  riser supplies substantially the only mooring force most  of  the  time,  while  thruster  equipment  on the vessel  supplies  sufficient  additional  force  a small amount  of  the  time  to  limit vessel drift in violent storms.    The  upper  several  meters of the riser is a rigid  pipe, and an instrument that measures tilt of the pipe  indicates the amount and direction of drift of the vessel.

Title: Vocal muffler
Inventor: BOYNTON CARTER R
IPC: A61J17/00
Filed: 1988-08-30
Granted: 1993-06-22
Abstract: ABSTRACT   A vocal muffler for muffling the vocalization of a human, especially a crying baby.  The muffler comprises a globe-like member having a chamber provided with a port positionable over the baby's mouth and via which the baby's crying enters the chamber to exit through muffled port means in bypassing relation to an inhalation port.  A valve in the chamber opens the inhalation port during inhalation by the baby and closes the port in response to exhalation.  The bypassing port means includes sound-attenuating means for muffling the baby's cries.  The valve is contained loosely in a cage adjacent to the inhalation port so that when the muffler is not used as a muffler, the ball will rattle in the cage and the muffler serves as a toy rattle.

Abstract: ABSTRACT         A microbridge air flow sensor having a silicon nitride diaphragm formed on the surface of a single crystal silicon wafer.  A rectangular 500 angstrom thick sacrificial layer was deposited on the silicon surface before the silicon nitride to define the exact position of the diaphragm.  A series of etches from the backside of the wafer is performed to fabricate the device.  A first silicon anisotropic etch from the backside is stopped at the sacrificial layer.  A sacrificial layer selective etch is applied from the backside first pit to the sacrificial layer to remove all of the rectangular sacrificial layer.  Anisotropic etch is again applied into the space created by the removed sacrificial layer whereby the second etch attacks the silicon exposed by the removal of the sacrificial layer and etches downward forming a second anisotropic etch pit.  Thus all the etches are from the backside of the silicon wafer.

Abstract: "Dual-Mode Teleconferencing System"                     ABSTRACT OF THE DISCLOSURE In a teleconferencing system, a video encoder at the transmit end of the system includes a frame memory for storing video samples of a frame of a motion-picture signal and reading video samples at frame intervals. For still-picture transmission, an encoder circuit translates video samples read out of each successively shifted location of the frame memory which corresponds to at least one scanning line period of the frame info a signal representative of an interframe correlation between adjacent video samples and generates a signal of a constant value during remaining line periods of the frame. For motion-picture transmission, video samples of the motion-picture signal for at least one scanning line period are translated into a signal representative of the intraframe correlation and video samples of remaining line periods of each successive frame are translated info a signal representative of the interframe correlation between successive frames. A video decoder at the receive end recovers a video sample from successively received intraframe correlation representative signals, delays it for a frame period to recover a video sample from the delayed sample together with a subsequently received signal which is the constant value signal during the still-picture mode and which is the interframe correlation representative signal during the motion-picture mode. The decoder further delays the last-mentioned video sample for a frame period to repeat the recovery process.
