Patent CA-2510937-C (CA)
Inventor: AMPULSKI ROBERT STANLEY
IPC: D21F7/00
Filed: 2000-05-30
Granted: 2008-07-22
Abstract: A papermaking belt (90) comprises a reinforcing element (50) and a resinous framework (300) joined together. The resinous framework (300) is formed by a plurality of resinous beads (110) which mutually contact or cross-over. Super-knuckles (160) extending outwardly from the reinforcing element (50) are formed at points of contact. A preferred continuous process for making the belt comprises extruding, in a pre-selected pattern, a plurality of beads (110) of a resinous material onto the forming surface thereby forming the resinous framework (300) thereon, joining the resinous framework (300) and the reinforcing element (50) together, and then solidifying the resinous framework (300). The resinous material may comprise at least two chemically-active materials capable of cross-linking upon contact.

Title: Device for estimation of brine density
Inventor: CHAUHAN SHANTI AMRITLAL
IPC: G01N9/00
Filed: 2002-12-23
Granted: 2011-10-18
Abstract: The present invention relates to a novel device that enables a person to gauge the brine density in solar salt works from afar without recourse to sampling of the brine. The device - which can be considered as an improvement over the conventional laboratory type Baume meter - can be placed directly in the salt pan. The device remains sunk, and therefore invisible, until the desired density of brine is approached. Thereafter it gradually floats up and becomes visible from afar. From appropriate markings on the rod connected to the top end of the device, it can be gauged whether the brine is yet to attain the desired density, or has attained the desired density range, or has exceeded the desired density range. The device is resistant to corrosion and able to combat extreme weather conditions prevailing in solar salt works. The control of brine density form afar helps eliminate the need for frequent sampling of brine for density measurement that would make adherence to the optimum process of salt production easier. The methodology can be extended to production of other marine chemicals such as carnallite and kainite.

Title: Identity-based encryption system for secure data distribution
Inventor: KACKER RISHI R
IPC: H04L9/08
Filed: 2004-02-03
Granted: 2013-12-31
Abstract: A system is provided that allows encrypted content to be distributed to users over a communications network. A policy enforcement service may use an identity-based encryption algorithm to generate public parameter information and private keys. Data content may be encrypted prior to distribution using an identity-based encryption engine. The encryption engine may use the public parameter information from the policy service and public key information to encrypt the data. The public key information may be based on policy information that specifies which types of users are allowed to access the data that is encrypted using that public key. A user may obtain a private key for unlocking particular encrypted data by providing a key request to the policy enforcement service that contains the public key. The policy enforcement service may enforce the policies given by the policy information and may provide private keys only to authorized users.
