Title: Method for providing electromagnetic shielding and diffusion barrier properties of plastic extrusion and devices fabricated therefrom
Inventor: LAMBERT WILLIAM ROGER
IPC: B32B15/08
Filed: 1997-02-17
Abstract: A method for fabricating a coextruded part includes a multiple layer sheet.  First, an extruded part is fabricated which can include a complex interior structure. Then, a multiple layer sheet material is formed into a tube surrounding the first extruded part and bonded to the outer surface.  Next, the composite structure then enters a second extrusion die and an outer layer of a second polymeric material is coextruded over the structure to form the outer surface.  Thus, the multiple layer sheet embedded within the coextruded part imparts diffusion barrier and electromagnetic shielding capabilities to a complex extruded part in a continuous and cost effective manner.

Title: End-to-end session recovery
Inventor: SHEH YI-REN P
IPC: H04L29/06
Filed: 1997-03-07
Abstract: A session recovery mechanism that permits the recovery of a session with a minimal delay to a user and with minimal data loss. When the client/server communications protocol process, such as TCP/IP process, issues an error message to a server and a client, the server and the client switch from a server data socket and a client data socket, respectively, to a new server data socket and anew client data socket, respectively. This switchover is achieved by having the client open a listening socket during its initialization process. Using the client listening socket, the client listens for a connection from the server to switch to a new data socket, in case of, for example, error messages from the TCP/IP process.

Inventor: DINSMORE JONATHAN
IPC: A61K35/30
Filed: 1995-11-07
Abstract: Porcine cortical cells and methods for using the cells to treat neurological deficits due to neurodegeneration are described. The porcine cortical cells can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine cortical cells can be modified such that an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject. In one embodiment, the porcine cortical cells are obtained from a pig which is essentially free from organisms or substances which are capable of transmitting infection or disease to the recipient subject. The porcine cortical cells of the present invention can be used to treat neurological deficits due to neurodegeneration in the brain of a xenogeneic subject (e.g., a human with epilepsy, head trauma, stroke, amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, or Huntington's disease) by introducing the cells into the brain of the subject.

Inventor: LIU SHEN-CHUNG
IPC: H04J3/12
Filed: 1997-07-21
Abstract: The protocol of the invention modifies the standard Universal Asynchronous Receiver/Transmitter transport to support a data message that is contained in a frame that is a logical grouping of bytes. In one embodiment, the first byte of each frame includes a start bit and stop bit, a length of message indication and the parity bits for the entire message or frame. The other bytes in the frame each include a stop bit, start bit and eight bits of data. All of the bytes in the frame substitute a frarning bit for the parity bit found in the existing protocol. This embodiment of the invention allows data messages of varying length with minimum overhead. Alternatively, for messages having a length of greater than 6 bytes, the first byte of the frame is used to define the length of frame. The last byte or last two bytes of the frame contain error checking bits. The remaining bytes of the frame contain payload data. This arrangement allows messages of virtually any length.

Patent CA-2221477-A1 (CA)
Title: Mechanical split double seals
Inventor: REAGAN MICHAEL P
IPC: F16J15/46
Filed: 1997-11-19
Abstract: Split mechanical seal assemblies which include a pressurized fluid barrier and multiple concentric and axially aligned stationary seal rings. The stationary seal rings are in sealing relation with a rotary seal ring at their respective seal faces, and with the gland of the mechanical seal assembly, thereby forming an annular cavity for pressurized fluid to create a positive fluid pressure barrier across the seal faces when in sealing contact with each other. The axially and concentrically aligned stationary seal rings comprise an inner stationary seal ring and an outer stationary seal ring, and the area of the axially extending portion of the outer surface of the outer seal ring partially defining the annular cavity is greater than the area of the axially extending portion of the inner surface of the outer seal ring partially defining the annular cavity. The split configuration of the seal assembly facilitates quick installation, removal and maintenance of the seal assembly and its component parts. The seal assembly is also compact in design on account of the concentric and axially aligned stationary seal rings, permitting installation and maintenance of the assembly and its component parts under circumstances where space is limited. These benefits are provided without sacrificing the function benefits of a pressurized fluid pressure barrier as a supplement to the seal between the stationary and rotary seal rings.
