Patent CA-2350778-A1 (CA)
Title: Improvements in or relating to buffer management
Inventor: REEVE ANDREW
IPC: H04L12/70
Filed: 2001-06-14
Abstract: Described herein is a method for reassembling variable length packets from fixed length cells. When a variable length packet, for example, an Internet Protocol (IP) packet, is transmitted between routers over a link which transmits data as fixed length cells, for example, an asynchronous transfer mode (ATM) link, the packet must be segmented into compatible fixed length cells. The receiving router must reassemble the original packet from the cells as they arrive. A packet buffer free pool (300) is provided which is maintained as a linked list, known as a 'free list', and which comprises a plurality of buffer elements (302, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322, 324, 326, 328, 330, 332, 334, 336, 338, 340). When a first cell for a given packet arrives, a buffer element (302) is taken from the head of the free list and allocated to that packet. The packet data from the first and subsequent cells is copied into the allocated buffer element and each time the buffer element is moved to the end of the free list. Upon the arrival of the last cell for the given packet, the complete packet is processed. Failed reassemblies are automatically abandoned as the buffer element is reused when it reaches the head of the free list. This technique is relevant to protection against "denial of service" attacks upon computer networks.

Title: Apparatus and method for sterilizing, seeding, culturing, storing, shipping and testing tissue, synthetic, or native vascular grafts
Inventor: BAUMGARTNER MARK F
IPC: C12N5/077
Filed: 2000-01-14
Abstract: An apparatus and method for sterilizing, seeding, culturing, storing, shipping, and testing vascular grafts and other prosthesis is disclosed.  Specifically, the present invention relates to an apparatus and method for seeding and culturing vascular grafts with human cells. The apparatus includes a fluid reservoir, a pump, an alternating pressure source, and at least one treatment chamber. In accordance with the present invention, fluid is pumped directly through the vascular graft located within the treatment chamber, subjecting the vascular graft to radial and shear stresses. In addition, the alternating pressure source expands and contracts the treatment chamber, thereby applying a varying axial stress to the scaffold positioned within the treatment chamber. Applying shear, radial, and axial stresses to the vascular graft during seeding and culturing simulates the physiological conditions experienced by the graft once implanted.

Patent CA-2370184-A1 (CA)
Inventor: ARGO TIMOTHY D
IPC: A61F2/90
Filed: 2000-04-14
Abstract: A multi-section stent includes a connecting structure that allows the stent sections to move and flex relative to one another. For deployment and positioning, the connecting structure connects the multiple stent sections a nd holds the stent sections substantially stationary relative to one another. Following deployment, the connecting structure allows the multiple stent sections to move relative to one another. Movable stent sections enable flexure of the stent upon deployment within a body lumen. This flexing structure allows better conformance of the stent to the shape of the body lumen, and exerts less overall pressure against the lumen wall, reducing the  potential for trauma. Upon deployment, the multiple stent sections may be completely detached from one another. Alternatively, the stent sections may remain partially connected in a manner that allows substantial independent movement. The connecting structure can be manufactured to separate upon deployment, for example, by breaking or degrading within the body lumen in which the stent is positioned.

Patent CA-2375713-A1 (CA)
Title: Casting method and apparatus
Inventor: PARKS ARTHUR D
IPC: B22C9/24
Filed: 2000-06-30
Abstract: The use of green sand is eliminated by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block. In the process, a mold assembly (20) is formed from the same core sand that is used to form the core elements (23) defining the internal passageways of the casting. A mold-core carrier (10, 30, 40) is constructed with tapered sides (11, 31, 41) that hold the assembled mold (21, 22) and core elements (23) together during pouring of the molten iron alloy into the mold-core assembly (20) and the cooling period to form the casting. Although the carrier (10) sides can use a refractory liner (11), preferably the sides (41) are made of replaceable sheet metal backed by an open structural framework (42) to enhance cooling of the casting. After the casting is formed, the core sand from both the mold elements (21, 22) and the core elements (23) is recovered, and may be recycled and processed to form further mold elements or core elements or both.

Title: An apparatus and process for pre-hydrolysis of biomass
Inventor: GARCIA PINATTI DALTRO
IPC: C13B10/14
Filed: 2000-06-23
Abstract: This invention refers to an apparatus for the processing of pre-hydrolysis of biomass, particularly a reactor of the failsafe type, either mobile or not, which may be manufactured of microbonded carbon steel and coated with special materials (refractory metals, superalloys, stainless materials, plastics, etc.).  The insertion of vacuum between the shell of the reactor and its coating prevents its implosion and permits the detection of leakage with helium gas. The resistance to corrosion of the refractory metals enables carrying out of pre-hydrolysis and mineral digestion. In the process of this invention, biomass is compacted at 300 kg/m3 by a helical feeder, degased, flooded, heated, stirred, pre-hydrolyzed, the sugar being recovered at a first washing within the reactor with values higher than 90 %. The low liquid/solid ratio = 2 enables one to achieve sugar content of 10 bricks in the pre-hydrolysate and a consumption of 6 % of the energy contained in the processed biomass. The pre-hydrolysate is constituted by solutions of xylose and others and is intended for the production of furfural, alcohol and xylitol. The control of the process enables one to produce cellulignin with a high specific surface, 2 m2/g (measured by BET), compared with the value of 0.4 m2/g of non-hydrolyzed biomass, maintain crystallinity of the cellulose fibers, aiming at grinding it into fine particles (f <)250 mm), globulizing the lignin, exposing the cellulose to attacks by microorganisms from cud of ruminants, fungi, bacteria or enzymes in microbiological or enzymatic fermentation. The catalytic combustion due to the large specific surface results in a new fuel for boilers, combustors in general and MHD when produced with filtered water, and for gas turbines when produced with deionized water.
