Title: Portable electronic security key for electronic article surveillance device
Inventor: MAITIN STEVEN R
IPC: G08B13/24
Filed: 2003-09-05
Abstract: An electronic key (1) capable of reinitializing or resetting a security disabled electronic article surveillance (EAS) device is provided. The electronic key (1) can be a secure, portable, and battery (4) powered for initializing a secured EAS system's security protocol to factory default state, or to another preselected state. The key (1) has its own set of security protocols to prevent unauthorized use and can easily be reprogramme d for a wide variety of other functions including, but not limited to, firmwar e upgrading, diagnostic testing, and the like. The key (1) can be connected to the programming port of an EAS device and perform a preset reprogramming operation, resetting activated security features. The key (1) could be purchased for customer use, and would be secured by preselecting the total number of uses, such as one use. The one-time use would begin once the key ( 1) is activated. Activation of the key (1) is also uniquely controlled to preve nt its misuse. In one embodiment, the electronic key (1) must detect the interrogation field of a properly functioning EAS exit system prior to becoming enabled. The allowed usage can be limited by time, the number of units reprogrammed, or a combination of both. Once the key (1) has been activated for its pre-selected number of uses and shuts off, only qualified service personnel can reset the electronic key function for further uses.</S DOAB>

Title: Oxides of manganese processed in continuous flow reactors
Inventor: BOREN RICHARD M
IPC: C01G45/02
Filed: 2004-01-28
Abstract: Methods and systems for regenerating and pretreating oxides of manganese and precipitation of oxides of manganese from manganese salt solutions. Oxides of manganese, a slurry containing oxides of manganese or manganese salt solutions are mixed with heated aqueous oxidizing solutions and processed in a continuous process reactor. Temperature, pressure, Eh value, and pH value of the mixed solution are monitored and adjusted so as to maintain solution conditions within the MnO2 stability area during processing. This results in regenerated, pretreated and precipitated oxides of manganese having high or increased pollutant loading capacities and/or oxidation states. Oxides of manganese thus produced are, amongst other uses; suitable for use as a sorbent for capturing or removing target pollutants from industrial gas streams.  Filtrate process streams containing useful and recoverable value present as spectator ions may be further processed to produce useful and marketable by-products.
Patent CA-2517533-A1 (CA)
Inventor: SOLLAMI PHILLIP A
IPC: E02F5/14
Filed: 2005-08-30
Abstract: A compressible sleeve for fitting around the shank of a rotatable tool has a cut out portion at the forward end thereof. The sleeve is compressed to a diameter less than the inner diameter of the bore of a tool holder by an annular wear ring having a generally cylindrical central opening with a diameter larger than the diameter of the bore of the tool holder, but having an inwardly directed projection that retains the cylindrical sleeve in a diameter that is less than the diameter of the bore of the tool holder. When the shank of the tool is subsequently driven into the bore of the tool holder, the wear ring is forced forwardly along the sleeve until the projection of the wear ring falls between the cut out portions of the sleeve thereby allowing the sleeve to expand to the diameter of the bore of the tool holder. The outer walls of the cut out portion of the sleeve engage the ends of the inwardly directed projection of the wear ring thereby preventing the wear ring from rotating with the tool.
