Title: Fire and explosion suppression
Inventor: DUNSTER ROBERT GEORGE
IPC: A62C5/00
Filed: 2002-03-28
Granted: 2005-04-27
Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26,28). The source (5) of the water is pressurised by a feed (30) from the source of pressurised inert gas. The mass flow rate of the water will therefore reduce as the pressure of the gas decays. This tends to maintain the ratio of the mass flow rate of the water to the mass flow rate of the gas constant. This is found to produce and maintain an advantageous distribution of droplet size in the discharged mist. A control unit (10) adjusts a metering valve (7) in dependence on the mass flow rate or the pressure of the gas in order to adjust the ratio as necessary to maintain its value constant.

Title: Segregating anonymous access to dynamic content on a web server, with cached logons
Inventor: HICKS BRIAN C
IPC: G06F17/30
Filed: 2009-10-12
Granted: 2013-01-02
Abstract: A system and method are provided for segregating access to dynamic content on multiple websites hosted by a web server. When a request is received for dynamic content from a website, a UserRetriever module identifies a path to the content and retrieves a username and password corresponding to the website, from a database that is separate from the web server and used for other purposes (e.g., billing). A UserImpersonator module requests a logon handle for that username from a logon cache manager. The logon handle is used to associate the request with the impersonated user account instead of the default anonymous user account with which the request was initially associated. The dynamic content is retrieved and served under the context of the restricted impersonated user account session, after which the applied logon handle is stripped off and the request is re-associated with the default anonymous user account.
