Patent CA-2228515-A1 (CA)
Title: Radiation shielding and range extending antenna assembly
Inventor: DANIELS JOHN J
IPC: H04M1/17
Filed: 1995-08-01
Abstract: An antenna assembly for a radio transmitting device (10) includes a radiation absorber (80) defining an open curved shape in cross section, so as to define an open transmission area. A driven antenna (40) is disposed adjacent to the open transmission area so that during use some of the radiation emitted from the antenna (40) is absorbed by the radiation absorber (80). At least one parasitic radiation redirection element (322) receives radiation emitted from the antenna (40). The parasitic radiation redirection element (322) directs a portion of the radio signal toward the open transmission area, so as to extend a transmission of the radio signal transmitting device (10).

Title: Process for producing as-packaged instant cooking pastas and noodles
Inventor: FUKUYAMA TERUYASU
IPC: A23L7/113
Filed: 1998-06-09
Abstract: Dry pastas or noodles are heated with either wet or dry heat to convert their surface layer portion to the .alpha.-starch and, if the heating is done by wet heat, the moisture in the surface of the pasta or noodle strings is removed and, thereafter, the pasta or noodle strings are put into a sealable container, which is then injected with a specified amount of water and sealed, followed by reheating of the pasta or noodle strings. Pastas such as spaghetti and macaroni or noodles such as udon, soba, hiyamugi, kishimen and Chinese noodles can be cooked by just boiling them or a short time or heating them in a microwave oven and yet they develop the same texture as can be attained by fully boiling dry or raw pastas or noodles.

In a second embodiment, a bulb having a single opening into the interior is used. An inlet tube for drawing debris and water has one end inserted into the interior of the bulb. The bulb opening is also connected to an exhaust port to allow water to be forced out of the interior of the bulb. An inlet check valve is placed across the inlet tube and an exhaust check valve is placed across the exhaust port. A screen is positioned between the exhaust port and the interior of the bulb and will catch debris that has entered the bulb and is attempting to exit when the bulb is squeezed.

Title: Lignocellulose fiber filler for thermoplastic composite compositions
Inventor: JACOBSEN WILLIAM W
IPC: C08H8/00
Filed: 1999-07-19
Abstract: A discontinuous lignocellulose fiber is described for use as a reinforcing filler for thermoplastic composite compositions. The fiber filler includes a significant percentage by weight of long, "hair-like" fibers. Specifically, at least about 20 percent by weight of the fiber filler is discontinuous lignocellulose fiber with a fiber length greater than about 15 millimeters and a fiber diameter less than about 0.5 millimeters. A moldable thermoplastic composite composition including the discontinuous lignocellulose fiber comprises about 20 to about 50 percent by weight of the fiber filler and about 50 to about 80 percent by weight thermoplastic. The discontinuous lignocellulose fiber filler yields thermoplastic composite compositions having improved physical properties over basic thermoplastic. The improved physical properties can be achieved without the use of coupling agents, although coupling agents may be used to further enhance the composite properties. The discontinuous lignocellulose fiber is preferably derived from virgin, waste wood from either softwood or hardwood tree species depending on the end use of the composite composition. The thermoplastic can be selected from a number of post-consumer or post-industrial waste sources. Processes for the manufacture of the discontinuous lignocellulose fiber reinforcing filler and the thermoplastic composite compositions are also disclosed.
