Patent number: 7270775Abstract: An effective corrosion inhibiting polymer composition including an interceptor for an acid gas combined with known VCI ingredients produces a more effective VCI than the prior art composition. The composition in macrogranular form may be held in a receptacle which is sealed in a container in which ferrous articles are protected. When the composition, greatly diluted is injection- or blow-molded or extruded as film which contains more than 100 ppm of a 2,4-6-tri-substituted phenol and uniformly dispersed small amounts of solid micron-sized particles of interceptor, an alkali metal nitrite and a solid adjuvant to aid in dispersing the solid particles, the film is transparent and has a smooth surface.Type: GrantFiled: October 1, 2003Date of Patent: September 18, 2007Assignee: Northern Technologies International Corp.Inventors: Donald Alfons Kubik, Boris Varshal, Efim Ya Lyublinski, Barbara Ann Nygaard

Patent number: 7261839Abstract: An effective tarnish inhibiting (“TI”) polymer composition including a scavenger for hydrogen sulfide optionally in the presence of an acid gas such as sulfur dioxide, provides excellent protection against tarnishing of the lustrous surfaces of a silver object. When the composition is thermoformed into a box-like container or extruded as film which contains uniformly dispersed solid micron-sized particles of the scavenger chosen from zinc oxide and a silicate of an alkali metal in an amount no greater than 5% by weight of the polymer, it is transparent so that the condition of the stored silver may be assessed. A solid inert adjuvant may be added. All solid particles in the material have a primary particle size smaller than 53 ?m which makes it possible to obtain the uniform dispersion. A silver object may be wrapped in the film, or stored in a sealed box so that the solid particles in the polymer are not coated on the surfaces of the silver object.Type: GrantFiled: October 1, 2003Date of Patent: August 28, 2007Assignee: Northern Technologies International Corp.Inventors: Donald Alfons Kubik, Boris Varshal, Efim Ya.

Publication number: 20040173779Abstract: A biodegradable polymer (“biopolyrner) filled with more than 5 wt %, and up to about 35 wt % of an inert particulate filler so as to have a WVTR in the range from at least twice to about 50 times greater than that of low density PE having a melt flow index of 1 g/10 min, each of the same thickness, is more effective to protect metal parts against corrosion than “neat” or unfilled biopolymer. Moreover a cross-section of the filled biopolymer 0.025 mm thick, is substantially transparent if the neat biopolymer is transparent. The improvement in corrosion protection is obtained without decreasing the tensile strength of the film below a critical tensile strength of 2000 psi in either the machine or transverse direction, preferably in both directions, due to the uniformity of the dispersed particles in the filled biopolymer. Such uniformity is obtained because the ingredients in the biopolymer are essentially anhydrous.Type: ApplicationFiled: March 20, 2004Publication date: September 9, 2004Inventors: Mehmet A. Gencer, Donald A. Kubik, Ramani Narayan, Efim Ya Lyublinski

Patent number: 6419816Abstract: Combining an electroosmosis direct current (EP) applied at less than 1 mA/Mcm3 (milliamp per 1000 cm3 of concrete) with an anode placed adjacent an outer surface of reinforced concrete soaked with a substantially neutral saline solution, effectively depletes corrosive anions in the concrete even when the direct current is in the range from 0.01 mA to less than 1 mA and at a voltage less than 100 V. Further, using such electroosmotic treatment as a first treatment, and promptly following it with cathodic protection, preferably by an impressed cathodic current (CP) at a comparably low voltage, the current density of CP required for cathodic protection is unexpectedly reduced. This decrease in the required current density of impressed current CP, coupled with low installation and operational costs of the novel system, improves the efficiency of a conventional cathodic protection system, whether by impressed current or with sacrificial anodes, several fold, as high as by a factor of 3 to 30 times.Type: GrantFiled: January 16, 2001Date of Patent: July 16, 2002Assignee: Cor/Sci, LLC.Inventor: Efim Ya.

Patent number: 6387244Abstract: A steel-reinforced structure supplied with an aqueous solution of an inhibitor for the strucutre, is further protected against deterioration when an impressed cathodic current is applied; preferably the structure is continuously bathed in the inhibitor solution; flow of the first impressed current is maintained until flow is relatively constant at a level at least one-half the level at which the first impressed current was initiated. The concentration of ions is sensed by measurement of the current flow while maintaining a chosen voltage. The inhibitor solution may be used in conjunction with an electroosmotic current to drive ions into the concrete and towards the steel; this may be done prior to applying the cathodic impressed current, or concurrently therewith by providing secondary electrodes. Program controller means in the power station switches from one mode of delivery to another when current usage, measured by current density, is deemd to have become uneconomical.Type: GrantFiled: January 16, 2001Date of Patent: May 14, 2002Assignee: COR/SCI, LLC.Inventor: Efim Ya.
