Title: Shelf stable shaped grain products
Inventor: ZUKERMAN HAROLD W
IPC: A23L1/164
Filed: 1997-07-18
Abstract: This invention relates to a process for making shelf stable, shaped grain products, whose textures are comprised of visible, fully-cooked cereal grains joined together, and having said grains filled with a water solution containing soluble solids and an antimycotic agent. In the process of the present invention, whole cereal grains such as rice, oats, wheat, or other cereal grains are modified by either flattening the grains with cereal flaking rolls, creating small internal cracks in the grain structure, or cutting the grains into smaller pieces. The cereal grains are then cooked in a water solution with soluble solids and an antimycotic agent at temperatures over 190 F. Binders, such as starch, gums, or pectin are added to either gel the mixture or develop cohesive surfaced grains that become joined together. The cooked cereal grains which are now joined together, are formed into shapes with low shear forming equipment and heated and dried with an oven or hot air until their water activity falls below 0.85.

Title: Method and apparatus for bandwidth reuse in a communication network
Inventor: LU XIAOLIN
IPC: H04J3/02
Filed: 1997-10-10
Abstract: A method and apparatus is provided within a system having a total bandwidth divided into multiple segments. The segments are preferably frequency segments in a frequency division multiplexing environment or time slot segments in a time division multiplexing environment. The system transmits first downstream information from a head end to a router within a first bandwidth segment and transmits second downstream information from the head end to the router within a second bandwidth segment. The router sends the first downstream information to a first destination and sends the second downstream information to a second destination. First upstream information is transmitted from the first destination and through the router to the head end within a bandwidth segment used for downstream transmission other than the first bandwidth segment. Second upstream information is transmitted from the second destination and through the router to the head end within a bandwidth segment used for downstream transmission other than the second bandwidth segment. Upstream information from a given destination is always sent over a different bandwidth from the bandwidth over which the downstream information was received. Further, the router directs respective downstream information to respective EUs while blocking other information to maintain privacy of information.
Patent CA-2220864-A1 (CA)
Inventor: HUQ NISAR
IPC: A61F2/06
Filed: 1998-01-20
Abstract: In Interventional Cardiology it is often a challenge to stent bifurcation lesions because of the potential for loss of side branches. In this invention, the incomplete coil design on each side allows each branch of the bifurcation to be accessed without compromising the other branch.      This invention relates to a new type of coronary stent for angioplasty of bifurcation lesions.      It has been common with previous stems to have wide spacing between coils to allow access to side branches with the guide wire but really no current stent has this incomplete coil design to allow complete access to side branches. The currently available stents often cause loss of side branches with the resultant undesirable consequences such as myocardial infarction or ischemia.      I have found that the current disadvantages may be overcome by creating a stent with a coil design on one side and then just leaving the opposite side without any metal so that the side branch may be accessed with the second stent. This second stent is a mirror of the first stent with coils on the opposite side and free space again facing the bifurcation.      In terms of the specific stent design it will be a coil design. I refer to Figure 1 which illustrates the current problem with "stent jail" where the stent covers the area of bifurcation. Figure 2 illustrates the complete coil portion going into the incomplete coil portion. Please note in Figure 3 how portion "A" of the stent is deployed first. Then portion "B" is deployed down the opposite arm of the bifurcation.      The stent will be made of stainless steel. It will come in lengths of 10, 20, 30 and 40 mm. It will be delivered on a minimally compliant balloon without a sheath. The marker positions will be on either ends of the stent. */#/#/#/#/* will be how it will be marked. In the embodiment in the figures it is apparent how the side branch is protected as there is no metal to obstruct it.

Patent CA-2226652-A1 (CA)
Inventor: WAYNE RAMON
IPC: A47K3/12
Filed: 1998-03-23
Abstract: The invention relates to an adjustable, wall-mounted, shower-enclosure, support apparatus, adapted to provide, when required, enhanced protection against injury, through loss of balance, to a bather, using the shower in a bathtub-shower combination unit or, alternatively, a separate shower stall.     A bather who loses balance, for any reason, while taking a shower, is liable to fall in any direction. Yet, wall-mounted grab-bars in a shower-enclosure, generally, provide protection against that risk in only one or two directions.       To overcome that deficiency, the invention provides for an apparatus which incorporates a body-encompassing frame member that can surround the bather at a chosen height, when required, and thereby supply, in all directions within a horizontal plane, a reliable means of support which can be seized in an emergency or which can break a fall under certain circumstances, when the support cannot be used as intended.
