Title: Apparatus and method for the formation of heterogeneous ion-exchange membranes
Inventor: SNOW MICHAEL J
IPC: B29C48/38
Filed: 2000-11-14
Abstract: The present invention provides methods and apparatus for the formation of heterogeneous ion-exchange membranes by prescribed in-line compounding and extrusion of a polymeric binder and heat sensitive ion-exchange resin. The ion-exchange resin is incorporated, at a late process stage, into the melted matrix polymer at relatively low temperature and residence time prior to transfer to a die head for extrusion. In the presently preferred embodiment, the in-line compounding apparatus comprises a twin-screw compounding extruder, for effecting late stage kneading and mixing of ion-exchange resin and optional additives to the polymer melt, prior to compression to transfer the blended polymer melt to a die head for extrusion. Accordingly, the final properties of the resultant heterogeneous ion-exchange membrane are enhanced as the blended polymer melt material is not exposed to excessive heat and shear history. Resultant heterogeneous ion-exchange membranes and apparatus for treatment of fluid streams utilizing such membranes are also provided.

Title: Method for managing failures on dynamic synchronous transfer mode dual ring topologies
Inventor: HIDELL LARS MARKUS
IPC: H04Q11/04
Filed: 1998-07-24
Abstract: The dynamic synchronous transfer mode dual ring topology has two rings (12, 14) with opposite fiber directions (H1, H2). The dual rings may have a plurality of common nodes (A-F). A first channel (K) may be established in a first segment extending between the first and second nodes. Tokens associated with the first channel (K) may be provided. In this way, time slots may be transmitted in the first channel (K) from the first node to the second node.  If a fiber failure (U) occurs in the first segment, the second node is likely to first detect the fiber failure (U) and transmit a fiber failure message. It is then determined if the first channel (K) extends across the fiber failure (U). If the first channel is affected by the fiber failure (U) then a channel failure message is transmitted and the first channel (K) is terminated and all the tokens associated with the first segment are removed. If the first channel (K) is not affected then time slots are continued to be transmitted on the first channel (K).

Title: Internet authentication technology
Inventor: JOHNSON HAROLD J
IPC: H04L29/06
Filed: 1999-07-14
Abstract: The present invention relates generally to cryptography, and more specifically, to secure authentication of a First Computer Program to a Seco nd Computer Program. The approaches known in the art require that secure data positively identifying Client accounts be stored at a central location, eith er the Server or a Certifying Authority, requiring large overheads of memory an d computational power, and presenting obvious and high-value targets for attacks. The invention provides a means of authenticating Clients to Servers  without requiring confidential data to either be stored at the Server, or transmitted to the Server. The Client generates a series of one-time passwor ds by successive iterations of a non-reversible function on a seed value. The last value in the series is then sent to the Server to establish an account.  When the Client wishes to log on to his account, he sends the previous value  in the non-reversible series as his password. The Server can easily authenticate the Client by executing the same non-reversible function on the  password and verifying that is equal to the previous password. However, give n such a one-time password, there is no practical means for generating a prior  value in the non-reversible series. Therefore, even if the password is intercepted or the Server data accessed, there is no useful information available in either the transmission or the central storage.

Inventor: CHPIGANOVITCH VLADIMIR ANTON
IPC: F41H11/02
Filed: 2001-08-13
Abstract: There is provided a method and apparatus to protect the warhead of ballistic missiles from projectiles of antimissile defence system. It comprises:  creating, at a certain distance in front of the warhead, a layer of mechanical fragments with the same trajectory as that of the warhead and a density that will make it impossible for the projectile of an antimissile defence system to get through the layer without hitting one or more fragments. This layer is created by an apparatus that detaches from the warhead after the latter reaches an open space and moves into its required position using propulsion jets under control of its own navigation system. At the same time the warhead is equipped with 2 or more side jet engines or devices that can shoot the weight in a direction perpendicular to the trajectory of the warhead and give the warhead an impulse in that direction. In addition, the warhead is equipped with compact radar to determine the speed and/or distance to the projectile of the antimissile defence system and to give the signal to switch on the side jet engine or to shoot the weight.   After the warhead reaches an open space, the apparatus mentioned above moves into position in front of the warhead so that it has the same trajectory as the warhead but is removed a certain distance from the latter and creates a layer of fragments. When the projectile of an antimissile defence system reaches the layer of fragments it will hit one or more of them and cause damage or lose orientation. The radar on the warhead gives a signal to the side jet or to the shooting device to give the warhead an impulse perpendicular to its trajectory to avoid contact with the damaged and/or disoriented projectile of the antimissile defence system. The second side jet engine or shooting device is used to give the warhead an impulse in the opposite direction in order to keep it on a trajectory close to original one.

Abstract: A method for fabricating an optical device that uses a robust purified adhesive as a bonding agent is disclosed. Impurity particles greater than or equal to 0.1 microns are removed from liquid precursor materials prior to polymerization or cross-linking. The impurity particles are separated from the precursor by applying a high gravitational centrifugal force. The purified adhesive is used to bond together optical components disposed in the optical path of the device. The purified adhesive resists damage from high-powered lasers because impurity particles that would otherwise absorb and scatter laser light are removed from the adhesive.
