Publication number: 20070157675Abstract: A recovery system recycles the washwater used to clean excess binder and debris from the production components, including a forming hoodwall constructed of non-corrosive materials, for manufacturing fiberglass insulation. A separate closed-loop recovery system is provided for the forming hoodwall in which the binder-containing washwater is screened and then recycled back to the forming hoodwall without further chemical treatment to change the pH level. A binder reclamation system is coupled to the hoodwall washwater recovery system to divert the low pH washwater when the supply of binder needs replenished at the forming hoodwall. The binder reclamation system introduces an acid solution to the cleaned washwater to lower the pH from about 2.5 to about 3.5. The other production components share a bulk washwater recovery system in which a base solution is introduced to raise the pH to approximately 8 or above to reduce corrosion in the other production components.Type: ApplicationFiled: February 26, 2007Publication date: July 12, 2007Inventors: Harry Cline, William Downey, Liang Chen, William Cooper

Publication number: 20070000517Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment is provided. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system and in a washwater tank holding the washwater solution is determined to be below approximately 8.0. Maintaining the pH of the washwater solution reduces the corrosion rate of the glass fiber forming equipment that is typically associated with acidic binders. In a second embodiment of the invention, a closed-loop hoodwall reclaim washwater recovery system utilized in addition to the washwater neutralization system that allows for the recovery and reuse of a polycarboxylic acid binder with a minimal amount of base solution. The closed-loop hoodwall reclaim washwater system is not connected to the closed-loop washwater neutralization system.Type: ApplicationFiled: May 23, 2006Publication date: January 4, 2007Inventors: Harry Cline, William Downey, Liang Chen, William Cooper

Publication number: 20050218285Abstract: A portable holder for storing air guns and other hand tools is disclosed. In a preferred embodiment, the holder comprises: a generally-tubular body having two open ends, one of which is flared; a slit or gullet on one side of the body and extending longitudinally from the flared open end of the body partway down the body; and a plurality of magnetic discs or feet for removably, yet securely attaching the holder to a workstation having a ferrous surface. A related process for storing such tools comprises: orienting a generally tubular holder adjacent a workstation's metal side; removably affixing the holder to that metal surface by at least one magnet; slipping the particular tool into a flared end of the holder; and guiding a portion of the tool, such as an attached air hose or the tool handle, into a gullet of the holder to rest the tool and orient the hose or handle for easy retrieval of the tool from the holder.Type: ApplicationFiled: March 23, 2005Publication date: October 6, 2005Applicant: GUARDAIR CORPORATIONInventors: Mark Yorns, Thomas Tremblay, Brian Donovan, James Fletcher, William Downey

Publication number: 20050076987Abstract: An apparatus for monitoring a condition of a tire, such as tread belt separation, includes at least one sound monitoring device that is carried by a vehicle. The sound monitoring device produces a sound monitoring device output signal that is representative of the sound produced by at least one of the tires during rotation. A signal processing device is also present and includes a neural network. The signal processing device receives and processes the sound monitoring device output signal. A processing device output signal that is representative of a potential damage condition of the tire is produced. An indication device is present and receives the processing device output signal. The indication device informs a user of the vehicle that the tire is experiencing the potential damage condition.Type: ApplicationFiled: October 9, 2003Publication date: April 14, 2005Inventors: George O'Brien, William Downey

Patent number: 4642106Abstract: A manually manipulated implement and method of use thereof for facilitating the drainage of conventional ostomy pouches are disclosed. The implement includes a two-piece handle portion with an elongated engagement member extending from each, with hinge means connecting the handle pieces and engagement members of movement toward and away from one another between spaced and essentially contacting positions. When the pouch drain opening is positioned over a suitable receptacle, the pouch walls are placed between the elongated engagement members, which are then moved from the spaced position to engage the pouch walls firmly therebetween. The implement is then moved manually toward the drain opening, forcing the contents out of the pouch, into the receptacle. In the preferred embodiment the implement is of one-piece molded plastic construction and includes means for stabilizing the relative lateral position of the engagement members as the implement is moved along the pouch.Type: GrantFiled: February 2, 1984Date of Patent: February 10, 1987Inventor: William Downey
