Patent CA-2285344-A1 (CA)
Title: A zinc sulfur battery
Inventor: LICHT STUART
IPC: H01M10/36
Filed: 1998-03-31
Abstract: An electric storage cell (10) comprises a zinc anode (12) and a sulfur cathode (14), wherein the zinc and the sulfur are in contact with an aqueous solution (22) containing sulfur during the process of battery discharge. In this invention, specific conditions for the aqueous sulfur electrolyte are chosen to overcome the normal ineffectiveness of zinc oxidation in the presence of aqueous zero valent sulfur. Normally, a zinc anode (12) cannot be oxidized in an aqueous solution containing sulfur, because the product of the discharge would be zinc sulfide. This zinc sulfide is a highly insoluble salt and creates a layer which passivates the zinc and renders it completely ineffective to battery discharge. The performance of the battery is made possible by high OH- and HS- ion concentrations formed by the addition of salts to the aqueous zero valent sulfur solution, and permits effective and efficient battery discharge.

Title: Method and system for redirecting web page requests on a tcp/ip network
Inventor: BROTHERS JOHN D W
IPC: G06F17/30
Filed: 2000-01-21
Abstract: A method and system for redirecting web page requests on a TCP/IP network is described. The method may be performed by a web traffic monitor that intercepts at least a portion of web-based traffic from a client/subscriber on a network. Based on a predetermined criterion, the web traffic monitor either responds to the client/subscriber with an action other than that which was intended by the user or relays the traffic to the destination originally intended by the user. The predetermined criterion may be chosen from, among others, a time period that has elapsed since the last web page request issued from the client/subscriber, a particular IP destination address requested by the client/subscriber, or the client/subscriber's IP address. Once the predetermined criterion is met, the traffic monitor acts appropriately by, for example, substituting a replacement web page for the web page requested by the client/subscriber. Appropriate methods of returning the replacement web page to the client/subscriber include, but are not limited to, returning the replacement web page: (1) without ever returning the intended web page; (2) for only a predetermined period of time; or (3) in a secondary browser window that pops on top of the intended web page, which is returned in a primary browser window.
