Patent CA-2289887-A1 (CA)
Inventor: CLEAR KENNETH C
IPC: C23F13/02
Filed: 1999-11-18
Abstract: The present invention relates to a method of cathodic protection of reinforced concrete, and more particularly, to a method of maintaining or improving current delivery from an anode used in a cathodic protection system.  The method of the present invention comprises applying a conductive paint onto an exposed surface of the concrete in an amount effective to form a conductive paint anode bonded to the surface. The anode and concrete have an interface.      The conductive paint anode is permeable. The conductive paint anode is electrically connected to the reinforcement through a source of impressed current.      A lithium salt solution selected from the group consisting of a lithium nitrate (LiNO3) solution, a lithium bromide (LIBr) solution, and combinations thereof, is applied to the external surface of the anode after the conductive paint anode has been applied to the concrete. The lithium salt solution quickly and effectively migrates through the pores of the permeable anode to the interface between the anode and the concrete. The lithium salt at the interface functions to provide improved current delivery.      The lithium salt solution preferably comprises a surface active agent which wets the exposed surface of the conductive paint anode and facilitates migration of the solution through the anode to the interface of the anode with the concrete.

Inventor: PAVEL STEPHEN K
IPC: B01J38/66
Filed: 1999-04-05
Abstract: The present invention discloses aqueous methods for enhancing the acid sites of fluid catalytic cracking (FCC) catalysts. The methods comprise the steps of contacting an FCC catalyst, either spent or fresh, with an aqueous solution comprising water, an inorganic acid substantially free of chloride and aluminum. The acid is preferably sulfurous or sulfuric acid. The aluminum is provided by an aluminum source selected from the group consisting of the alumina trihydrates and aluminum oxide. Chloride contamination of the aluminum source should be minimal, preferably less than about 1000 ppm chloride, more preferably less than about 200 ppm chloride. The pH of the aqueous solution is adjusted to about 3-12 by the addition of a sufficient quantity of ammonium hydroxide. The FCC catalyst is added to this solution, preferably with stirring, in a weight ratio of about 1 part catalyst to about 1-10 parts water to prepare an aqueous slurry. Upon stabilization of the pH of the aqueous slurry, enhancement of the acid sites of the catalyst is achieved and the catalyst may be separated from the slurry and, if desired, washed. This simple, aqueous process reduces the level of many metal poisons on the FCC catalyst and produces a catalyst having an enhanced number of acid reaction sites.

Abstract: Ultraviolet (UV) laser output exploits the absorption characteristics of the  materials from which an electrically conductive link (42), an underlying semiconductor substrate (50), and passivation layers (48 and 54) are made to  effectively remove the link (42) without damaging the substrate (50). The UV  laser output forms smaller than conventional IR laser link-blowing spot diameters (58) because of its shorter wavelength, thus permitting the implementation of greater circuit density. A passivation layer positioned between the link and the substrate can be formulated to be sufficiently absorptive to UV laser energy and sufficiently thick to attenuate the laser energy to prevent it from damaging the substrate (50) in the laser beam spot area (43) in both the off-link and link-overlapped portions. The UV laser output can be employed to controllably ablate a depthwise portion of the passivation layer (54) underlying the link (42) to facilitate complete remov al of the link (42). In addition, direct ablation of the passivation layer (48)  with the UV laser output facilitates predictable and consistent link severin g profiles. The absorption characteristics of the passivation material also reduce the risk of damage to neighboring links or other active structures.</ SDOAB>
