Patent CA-2227158-C (CA)
Inventor: BOUDREAULT JEAN-PIERRE
IPC: F24C15/20
Filed: 1998-01-12
Granted: 2001-05-08
Abstract: The exhaust hood assembly has a vertically disposed greast extractor which leads into a suction ventilator adapted for expelling air and odor to the outside. The assembly has a first deflector at the entrance into the grease extractor to cause a first swirl of the air loaded with grease, impurities and odors, and a first release thereof into a bucket provided below the greast extractor. Inside the greast extractor there are two deflectors to cause swirls of the air load with grease and odor and release of grease and particles into the bucket. Finally, any grease and/or impurities not released in the grease extractor are centrifugally expelled by the suction ventilator and sent through a tube which also feeds into the bucket. This device is inexpensive to produce and is much more efficient than those currently in use.

Abstract: Gain control is performed on an input signal to an orthogonal modulator used in a radio transmitting apparatus in such a manner that the level of the input signal falls within the proper operation range of the orthogonal modulator.  At the time of amplifying and outputting the output of the orthogonal modulator, gain control is executed with the reciprocal of a control gain for the input signal to the orthogonal modulator.  Accordingly, the input to the orthogonal modulator of an adaptive array antenna can be compensated within the proper range to ensure the proper operation of the orthogonal modulator.

Granted: 2002-07-23
Abstract: A container for refrigerated dough or other expandable products and a condiment cup therein for containing icing and the like includes the following construction. The container has an elongate cylindrical body with an interior wall of a predetermined diameter and end closures. The condiment cup is of a flexible plastic generally cup-shaped construction having a generally cylindrical side wall closed at one end by a dome-shaped convex end and open at the other end. The cylindrical side wall has an outside diameter only slightly less than the diameter of the container interior wall so as to provide a loose friction fit when the condiment cup is positioned within the container cylindrical body portion. The condiment cup is filled with condiment and positioned within the container at one end of the cylindrical body portion with the open end of the cup facing the end closure at the one end. The container is filled with refrigerated dough or other expandable product, so that, as the product expands within the container, the product will push against the dome-shaped convex end of the condiment cup for flexing the cup end inwardly to cause flexing of the cup side wall outwardly to provide a tighter friction fit with the container interior wall to seal the condiments in the cup from the product in the container.

Abstract: An in vivo implantable sensor (10) obtains spectra of body fluid constituents, and processes the spectra to determine the concentration of a constituent of the body fluid. The sensor includes an optical source (12), and detector (16). The source emits light at a plurality of different, discrete wavelengths, including at least one wavelength in the infrared region. The light interacts with the body fluid and is received at the detector. The light at the plurality of different wavelengths has a substantially collinear optical path through the fluid with respect to each other. When measuring fluid constituents in a blood vessel (14), such as blood glucose, the light at the plurality of different wavelengths is emitted in a substantially single period of time. The spectra are corrected for artefacts introduced from extraneous tissue in the optical path between the source (12) and the detector (16).

Abstract: A sheet for protecting paint films of automobiles which can prevent the paint film of automobiles from suffering from damages such as discoloration and denaturation even if rainwater or washer penetrates into the gap between the adhesive cover and the paint film while achieving excellent protection function to suspended matters, colliding matters, etc. inherent to protecting sheets and being easily peeled off and removed after completion of the desired protection. The sheet for protecting paint films of automobiles comprises a pressure--sensitive adhesive layer having a roughened surface provided on a substrate made of fiber sheet. Even when rainwater, washer, etc. penetrates into the gap between the pressure-sensitive adhesive layer and the paint film of automobiles from wrinkles formed thereon, the liquid diffuses by capillary action through the gap developed by the roughened pressure-sensitive adhesive layer, making it possible to avoid the residence and concentration of the penetrated dirty water and hence prevent the occurrence of damages such as discoloration and denaturation of the paint film. Further, the arrangement of a pressure-sensitive adhesive layer having a roughened surface reflecting the fiber constituting the protecting sheet, particularly a fibrous continuous roughened surface, makes it possible to further diffuse the contaminating dirty water and hence further avoid the retention and concentration of the penetrated dirty water. Thus, the damages on the paint film can be more securely prevented.
