Patent CA-2121513-A1 (CA)
Title: Thermoformable nonwoven fabric
Inventor: PIKE RICHARD D
IPC: D04H1/00
Filed: 1994-04-18
Abstract: The   present   invention  provides   a   resiliently compressible, cloth-like thermoformed article produced from a lofty nonwoven crimped-fiber substrate web containing a structural fiber component and an heat-activatable adhesive component and having a density between about 0.01 g/cm3 to about 0.1 g/cm3.  Additionally provided is a process for producing the thermoformed article.  The process includes the steps of heating the web to melt the adhesive component and to make the web pliable without melting the structural fiber component,  shaping the web on a mold by lightly applying a pneumatic or mechanical conforming pressure, and cooling the shaped web to solidify the melted adhesive component and  to  form  interfiber  bonds,  wherein  the thermoformed article has a density-over-area ratio between about 1 and about 1.8.
Patent CA-2121823-A1 (CA)
Title: Soft wing suspension
Inventor: DAWSON PAUL W
IPC: B64C1/26
Filed: 1994-04-21
Abstract: Most aircraft currently being manufactured today use some form of suspension system which will dampen the impact forces of landing and bumps on the ground. None of the airplanes manufactured today provide any means to dampen any sudden flight loads or bumps while flying, except for the flexing of the wing. My invention is to provide a means to provide relative movement between the fusealage and it?s supporting and controling structures (wings, stabalizers) during flight. It will also provide means to control the rate, neutral position and amount of movement these surfaces are allowed. By doing this the passengers in the airplane will enjoy a smoother ride, and fatigue loads on the entire airplane structure will be reduced. Inspection times and airframe life could be extended as it is known that aircraft which fly through turbulant air regularly (pipe line patrol) have shorter inspection times and airframe life. The dampened movement of the wing would also allow floats, wheels or skiis to be mounted directly to the bottom of the wing, which can now be used to absorb landing loads.

Patent CA-2151095-A1 (CA)
Title: Method and apparatus for sequentially staged combustion using a catalyst
Inventor: BOWKER JEFFREY CHARLES
IPC: F23C13/00
Filed: 1995-06-06
Abstract: A low NOx generating combustor in which a first lean mixture of fuel and air is pre-heated by transferring heat from hot gas discharging from the combustor.  The pre-heated first fuel/air mixture is then catalyzed in a catalytic reactor and then combusted so as to produce a hot gas having a temperature in excess of the ignition temperature of the fuel.  Second and third lean mixtures of fuel and air are then sequentially introduced into the hot gas, thereby raising their temperatures above the ignition temperature and causing homogeneous combustion of the second and third fuel air mixtures.  This homogeneous combustion is enhanced by the presence of the free radicals created during the catalyzation of the first fuel/air mixture.  In addition, the catalytic reactor acts as a pilot that imparts stability to the combustion of the lean second and third fuel/air mixtures.

Title: Reduced calorie fat component
Inventor: MAZUREK HARRY
IPC: A23D9/013
Filed: 1996-01-25
Abstract: Low calorie fat components which have a low solids content but a reduced tendency to exhibit the gastrointestinal side effects typically associated with liquid fat substitutes are obtainable by blending esterified propoxylated glycerin materials having a relatively high solids content at 21°C with certain liquefying agents. The liquefying agents are characterized by their compatibility with the esterified propoxylated glycerin and their partial digestibility. The low calorie fat components have improved organoleptic qualities as compared to the esterified propoxylated glycerin materials alone.

Title: Channel, power and pn-sequence assignment in a mobile dsss system
Inventor: KRUEGER THOMAS E
IPC: H04B1/707
Filed: 1994-07-27
Abstract: A method and apparatus for providing spread spectrum communications.  The apparatus starts with designated spread spectrum communications parameters, such as default transmitted power level, pseudo-noise (PN) sequence.  PN sequence length, and frequency channel, having values which are chosen to ensure that spread spectrum communications can be carried out between a first station and a second station. The apparatus of the invention then changes the values of the spread spectrum communications parameters to the minimum values necessary to provide a given level of communications reliability.  If the conditions facing the spread spectrum communication system change so that communications reliability falls below the given level, the apparatus resets the values of the spread spectrum communications parameters to the default levels and begins again to change their values to provide the given level of communications reliability.  If the apparatus establishes that communications can reliably be carried out with narrowband communications techniques, the apparatus changes the parameters to provide narrowband communications at the minimum acceptable power level.

Title: Loudspeaker system and enclosure
Inventor: CHE HUNG CHAN
IPC: H04R1/02
Filed: 1996-03-06
Abstract: A transmission line loudspeaker system comprises a loudspeaker (1) and a transmission line enclosure (2). The line (2) is of circular or elliptical cross-section for a circular or elliptical loudspeaker respectively to reduce near field reflections directly back to the loudspeaker and to reduce enclosure vibrations.  The line may be bent smoothly to avoid uncontrolled reflections at the corners and may fold about itself (see Fig. 3).  The line may taper and include sound-absorbent wadding (6).  The line (2) and loudspeaker (1) may be mounted in a second box enclosure (4) for ease of handling and to isolate line (2) vibrations,  The end of the line (2) may includes a port (5) preferably formed from the second enclosure (4) to reflect back sound waves to the loudspeaker (1).  This doubles the effective line length, so that shorter lines (2) may be used.  Line length is preferably such that reflected waves enhance the speaker sound.
