Publication number: 20070196581Abstract: A process is described for coating a biodegradable item comprising the steps of dissolving from 10-25% ethylcellulose in 75-90% non-aqueous solvent to form a mixture; applying a layer of the mixture onto a surface of the item; and evaporating the solvent to form a coating of from 0.15 g to 0.30 g per 100 cm2 on a dry basis. The ethylcellulose may comprise Ethocel™, for example: Ethocel™ 20, Ethocel™ 45 or Ethocel™ 100. The process may be used to form a coating on biodegradable items that require a water barrier, for example cups, trays, or bowls made out of pressed starches, paper, or linted cellulose. Such items may appeal broadly as an environmentally-friendly packaging options.Type: ApplicationFiled: January 31, 2007Publication date: August 23, 2007Inventors: Elizabeth MARCU, Eve BELANGER

Publication number: 20060216246Abstract: The present invention relates generally to protective barriers. More particularly, an aqueous oral gel is provided containing food-grade ingredients. The gel is used to protect or isolate soft tissue of the oral cavity, or teeth, during a dental procedure such as tooth whitening. The gel can be applied to a surface within the oral cavity as a liquid, and sets quickly to form a pliable protective barrier that can be carved away to expose a portion of a tooth, one or more teeth, or any area of the oral cavity on which the dental procedure is to be performed.Type: ApplicationFiled: March 22, 2006Publication date: September 28, 2006Inventors: Eve Belanger, Elizabeth Marcu

Publication number: 20050238535Abstract: Provided herein are methods for preliminary analysis of suspect samples, which can be used in triaging possible contaminated sites (e.g., sites contaminated or thought to be contaminated by biowarfare agents). In some embodiments, the methods involve testing for the presence of protein in the suspect sample; optionally, the sample can also be tested for the presence of sugar, and/or for pH determination. Specific embodiment methods are carried out in tubes or other reaction vessels, others are carried out in a pad format, and still others are carried out in a test strip format. Kits for carrying out the described methods are also provided.Type: ApplicationFiled: January 27, 2005Publication date: October 27, 2005Inventors: Vladimir Knezevic, Dan-Paul Hartmann, Jonathan Cohen, Elizabeth Marcus, Gerard Troy

Patent number: 6923873Abstract: This invention concerns paint stripping compositions which are particularly suitable for stripping paint off aircraft. The basic composition consists of a mixture of specific amounts of the following substances: aromatic hydrocarbons, dimethyl formamide; N-methylpyrrolidone; benzyl alcohol; alkanolamine; wax; wetting agent; and thickening agent. A modified composition may also contain dimethyl sulfoxide and a terpene solvent. The invention also includes the method of stripping paint from an aircraft by applying the new stripping composition onto the surface of the aircraft allowing the paint to soften and loosen under the action of the composition, or to penetrate under the paint coating, and then gently removing both the loosened paint and the stripping composition from the aircraft surface without damaging the surface.Type: GrantFiled: January 18, 2002Date of Patent: August 2, 2005Assignee: Greensolv Environmental Products Inc.Inventors: Daniel Pageau, Elizabeth Marcu, David Aston

Publication number: 20040204493Abstract: Inhibitors of the alpha carbonic anhydrase inhibitors are administered to treat H. pylori infection in the mammalian, including human, stomach. The inhibitors are administered to mammals, including humans, in an amount that results in 4×10−4 to 4×10−9 Molar concentration of the drug in the stomach because this concentration range is lethal to the H. pylori bacteria.Type: ApplicationFiled: April 2, 2004Publication date: October 14, 2004Inventors: David R.

Patent number: 6771762Abstract: An AIN system having a service switching point (SSP), a service control point (SCP) and an intelligent peripheral (IPe) is disclosed. A calling party makes a call to a called party which results in a trigger signal at the originating SSP. The trigger signal causes the SSP to access the SCP which, in turn, sends a Send_to_Resource message to the SSP. In response to the Send_to_Resource message, the SSP establishes a first connection to an IPe, whose functionality is required. The IPe establishes a second connection carrying a second call to the called party, the first and second calls being connected at the IPe. The IPe subsequently requests that the SSP merge the first and second calls. In response, the call between the called party and the calling party is connected via the SSP, thereby releasing the IPe connections formerly used to connect calling and called parties.Type: GrantFiled: July 13, 2000Date of Patent: August 3, 2004Assignee: AT&T Corp.Inventors: Hwey Chang, Pamela Lilly DeFazio, Romel R. Khan, Maura Elizabeth Marcus, Gary A. Munson, Gautham Natarajan

Patent number: 6707886Abstract: A subscriber loop test apparatus relates to the testing of a subscriber loop by the use of a touchtone telephone. The touchstone buttons on a telephone provide Dual-Tone, Multiple Frequencies for each key pressed. For example, referring to FIG. 1, pressing the ‘3’ key causes tones at 697 and 1477 Hz to be sent across the telephone line. Pressing a sequence of keys provides discrete coverage of the frequency band from 697 to 1477 Hz, through the use of the touchtone telephone. The frequency band from 697 to 1477 Hz can be characterized in this fashion. Information about the line: loop loss (loop length), presence of bridge taps (i.e., excessively long bridge taps in particular) or loading coils, and the presence of Digital Loop Carriers (DLCs), et cetera. The use of the switch-hook flash provides the ability to determine the channel (impulse) response of the loop, including any noise and hum that may be on the loop due to imbalance or coupled interference.Type: GrantFiled: February 12, 2002Date of Patent: March 16, 2004Assignee: AT&T Corp.Inventors: Richard Henry Erving, Maura Elizabeth Marcus, Robert Raymond Miller, II, Christopher W.

Patent number: 5818919Abstract: An automated intelligent network system and method for providing automatic forwarding of calls to enhanced telecommunications service platforms across network boundaries while preserving subscriber identity. In accordance with the present invention, the values of defined parameters that are maintained with a call according to established network protocols and passed between networks during call processing are controlled such that, using these controlled values, the subscriber identification information reaches the platform where the enhanced service is implemented in different network than that of the service subscriber. An alternative embodiment of the invention provides a way for enhanced telecommunications services platforms to identify both the subscriber and the calling party when calls are automatically forwarded to the platform across network boundaries.Type: GrantFiled: July 15, 1996Date of Patent: October 6, 1998Assignee: AT&T Corp.Inventors: Edward Charles Berberich, Jr., Siang Gek Heng, Susan Suh-Jen Lee, Maura Elizabeth Marcus, Courtney Aldington Pinnock, John Richard Rosenberg, John James Schubel
