Title: A polymer-fibre prepreg, a method for the preparation thereof as well as the use of said prepreg
Inventor: VALLITTU PEKKA
IPC: A61K6/90
Filed: 1996-02-19
Granted: 2005-05-03
Abstract: The invention relates to a method for the preparation of the fibre product pre-impregnated with a polymer (prepreg) wherein the method comprises: a) coating the fibres with a powder comprising at least one polymer and optionally an agent having the ability to initiate the polymerization reaction of said polymer, b) adding to the composition obtained in step a) a solvent possessing the ability to dissolve said polymer but lacking the ability to initiate the polymerization reaction of said polymer, and c) evaporating the solvent. Alternatively, the polymer (optionally including the initiating agent) can first be dissolved in the solvent after which the fibres are contacted with the solution thus obtained and the solvent is evaporated. The surface of the fibres is preferably treated so as to facilitate the bonding of the polymer to the fibres, whereafter the surface treated fibres are coated with the polymer powder. The invention relates further to a novel prepreg, a method for the manufacture of fibre reinforced composite based on the use of said prepreg, the novel composites and their use.

Abstract: A process for bending a thermoplastic skinned honeycomb core panel includes clamping a planar portion of the panel to hold the panel against movement parallel to the plane of the planar portion. A linear band of a face sheet on one side of the panel is heated to soften resin and disbond adhesive holding the face sheet to the honeycomb core. The heat is removed, forming a bubble separated from the core. A distal leg of the panel is bent around a heated anvil along an axis parallel to the linear band to form a bend having an inside radius. The bubble collapses around the inside radius and forms an overlapping flap of face sheet. The flap is pressed in a fold between the anvil and the bent leg of the panel, and the leg is held in the bent position while resin in the flap solidifies.

Title: Contents transmission control method with user authentication functions and recording medium with the method recorded thereon
Inventor: HAMADA HIROSHI
IPC: H04L12/58
Filed: 1997-09-08
Granted: 2001-12-25
Abstract: A user sets n=0, his mail account A and password S, then computes V0=E(A,S), W0=E(A,V0), V1=E(A,A~1), W1=E(A,V1) and M0=E(W1,V0), and initially registers W0, W1, M0 and A by e-mail in a mail server. At a visiting site the user sends a service request and A to the mail server from an arbitrary terminal connected to the Internet, and the mail server reads out the authentication session number n corresponding to the identifier A and sends it back to the user. The user computes V n-1=E (A,S+~(n-1)), V n+1=E(A,S~(n+1)), W n+1=E(A,V n+1)-V n=E(A,S~n) and M n=E(W n+1,V n) and sends V n-1, W n+1 and M n to the mail server. The mail server computes E(A,V n-1) and E(W n,V n-1) and if they agree with preregistered W n-1 and M n-1, respectively, the mail server accepts the user as valid and sends a mail message of the user.

Title: Methods for detecting colon cancer from stool samples
Inventor: ULMER KEVIN M
IPC: C12Q1/68
Filed: 1996-12-20
Granted: 2003-02-18
Abstract: The present invention provides methods for screening for the presence of a subpopulation of cancerous or precancerous cells in a heterogeneous cellular sample, such as a stool sample. The methods take advantage of the recognition that cellular debris from cancerous and precancerous cells is deposited onto only a longitudinal stripe of stool as the stool is forming in the colon. Accordingly, methods of the invention comprise obtaining a representative sample, such as a cross-sectional sample of stool in order to ensure that any cellular debris that is shed by colonic cells is obtained in the sample.

Granted: 2003-10-07
Abstract: A method of provisioning a local number portability capable communication network which comprises numerous service provider networks, with updated signalling routing information to reflect a porting change is disclosed.  A central administration center first updates the ported to network with updated signalling routing information.  After the ported to network has been successfully updated the central administration center then proceeds to update all intermediate service provider networks. After confirmation has been received that all intermediate networks have been successfully updated the central administration center then proceeds to update the ported from network.  Provisioning of networks which include intermediate networks supported by a central administration center in the predetermined manner and sequence disclosed can advantageously prevent signalling messages from looping between non-synchronized networks. The provisioning sequence works equally well where only two networks are involved, i.e. the ported from and ported to networks.
