Title: Laryngeal mask airway with concentric drainage of oesophagus discharge
Inventor: BRAIN ARCHIBALD I J
IPC: A61M16/06
Filed: 1993-07-21
Granted: 1996-07-23
Abstract: A laryngeal mask airway is described which is fitted with an evacuation or drainage tube which passes through the back of the mask and terminates concentrically within an inflatable-cuff formation at the distal end of the mask.  In the case of a laryngeal mask which relies on an inflatable ring to establish a seal around the laryngeal inlet, the inflatable-cuff formation results from sealed passage of the evacuation tube through the distal region of the inflatable ring, the distal end of which is centrally apertured and re-entrantly folded into sealed junction with the distal end of the tube.  When the mask is inflated, its distal end establishes a cuff, sealing the tube against the upper oesophageal sphincter.  In the presently preferred embodiment, an auxiliary inflatable cuff is carried at the back side of the mask and, when inflated, establishes a cushioned reference between the evacuation tube and the posterior wall of the pharynx, enabling more effective sealing of the mask to the laryngeal inlet and of the drainage cuff to the oesophageal sphincter, in the circumstance of negative pressure applied to the evacuation tube.

Title: System for, and method of, displaying information from a graphics memory and a video memory on a display monitor
Inventor: SIANN JONATHAN I
IPC: G06F3/0484
Filed: 1994-02-04
Granted: 2001-04-10
Abstract: A display memory respectively stores, in first and second portions, digital graphics data for display in a video monitor and digital video data for display in a window in the monitor. The digital video data is transferred from the display memory to a shift register at a rate different from the pixel clock and from the shift register at a clock rate that may be lower than the pixel clock rate. The video data may be stored in a luminance and chrominance format and may be converted by a color space converter to 3 bytes representing the primary colors red, green and blue. The video pixels may then be interpolated to expand the number of. video pixels.      The shift register operation may be synchronized with such expansion so that data is not passed from the shift register until the expansion of previous data from the shift register has been completed. Video window logic provides for the passage of the graphics pixels through a digital multiplexes at the graphics clock rate at the monitor positions outside the window and the video pixels from the shift register through the color pace converter and the interpolator at the monitor positions within the window. The graphics data may be delayed by a delay corresponding to that of the color space converter and the interpolator. The digital data passing through the multiplexes are latched at the graphics clock rate and are then converted to analog signals for display as a color image on the video monitor.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure.  The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits.  The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network.  The papermaking belt is made by casting a photosensitive resinous material over and through the reinforcing structure while the reinforcing structure travels over a textured surface, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions.  A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source.  Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Patent CA-2186321-C (CA)
Inventor: FOSTER JAMES JOSEPH
IPC: D21C5/02
Filed: 1996-09-24
Granted: 2002-05-28
Abstract: This  invention relates  to  recently  developed systems which produced bleached recycled fibers from high lignin  content  recovered  paper materials  such  as  old corrugated containers and old newspapers.  Such systems of this type, generally, use chemical digestion (e.g.,  the kraft process)  to reduce  the  lignin content  prior  to bleaching.  Since recovered paper materials normally have high levels of aluminum, which are derived from the paper sizing and pH control chemical, aluminum sulfate; and since soluble aluminum causes scaling of evaporators in the kraft digestion-chemical recovery cycle, there is a need for a means to remove soluble aluminum from the recovered paper materials prior to digestion.
