Patent number: 10695795Abstract: A fireproof, translucent, flexible coated fabric composite materials for use in fire curtains. The composite material meets or exceeds regulatory requirements in terms of fire endurance and allows transmissivity of necessary amounts of light. The process of the present disclosure combines a silica fabric with a special refractory index controlled resin. This unique combination of materials can transform an opaque high temperature fabric into a translucent, and even transparent, composite which as the ability to resist high temperature, flame and smoke penetration that fills a needed gap in technology between visibility and fire resistance in the field of fire and smoke curtains used in civil construction.Type: GrantFiled: October 9, 2018Date of Patent: June 30, 2020Assignee: Fire Curtains, Inc.Inventor: Douglas J.

Publication number: 20190003248Abstract: A fire shutter for preventing the spread of fire and smoke through an opening such as a door in a building structure that is resistant to pressure from a high-pressure hose. A flexible coated fabric composite, using high-temperature and high-pressure resistant materials. The shutter combines two layers of texturized fiberglass fabric, wherein each layer combines fiberglass and wire strands, with one strand wrapped in a spiral around the other, in both the warp and weft directions. The fabric is impregnated with vermiculite. Each layer of fabric, containing the fiberglass and wire strands, is coated, on an outer portion, with a high temperature stabilized, functionally filled polymer. After exposure to an extreme temperature condition, immediately followed by a standard hose test, the fire shutter functions as a fire partition, without smoke, fire or water penetration, while remaining flexible and allowing for egress.Type: ApplicationFiled: May 25, 2018Publication date: January 3, 2019Applicant: U.S Smoke & Fire CorporationInventor: Douglas J.

Patent number: 8599582Abstract: A control circuit includes a feedback circuit, a drive signal generator, an unregulated dormant mode and output reset control circuit, and a counter. The feedback circuit generates an enable signal and in response, the drive signal generator regulates the output of the power converter. The unregulated dormant mode and output reset control circuit powers down the drive signal generator such that the regulation is ceased when the energy requirement at the output has fallen below a threshold. The drive signal generator is then powered up after a first period of time such that the regulation resumes. The counter then counts cycles of a clock signal for which the enable signal indicates an increase in the energy requirement at the output. The counter disables the drive signal generator when a count of the counter reaches a threshold number to discharge the output to less than a regulation output voltage value.Type: GrantFiled: February 4, 2013Date of Patent: December 3, 2013Assignee: Power Integrations, Inc.Inventors: Douglas J. Bailey, David Michael Hugh Matthews

Patent number: 8385088Abstract: An implementation of an unregulated dormant mode with an output reset controller in a power converter is disclosed. An example method for controlling an output of a power converter includes generating a drive signal with a drive signal generator to regulate a flow of energy to one or more loads coupled to an output of the power converter in response to an energy requirement of the one or more loads. The drive signal generator is rendered dormant to cease for a first time period the regulation of energy flow to the one or more loads when the energy requirement of the one or more loads falls below a threshold value. The energy requirement of the one or more loads is not responded to during the first time period. The drive signal generator is then powered up to resume after the first time period has elapsed the regulation of energy flow to the one or more loads. After the first time period has elapsed, it is identified whether there is an increase in the energy requirement of the one or more loads.Type: GrantFiled: December 6, 2010Date of Patent: February 26, 2013Assignee: Power Integrations, Inc.Inventors: Douglas J. Bailey, David Michael Hugh Matthews

Patent number: 4943465Abstract: Provided is a composite for use as thermal insulation in high temperature environments. The composite comprises a layer of randomly laid and oriented, fine diameter, heat resistant fibers interlocked together into the form of a shape sustaining paper having a high fiber index and two lateral surfaces, said paper being compressed to produce a paper which has a thickness of from about 0.01 to 0.50 inch and a density of about 6 to about 30 lb/cu.ft. A high temperature resistant scrim is disposed upon each of the lateral surfaces of the paper, and a network of abrasion-resistant, high temperature-resistant threads is stitched through the scrim and the paper such that the scrim is mechanically locked to the paper by said threads. The network of threads and the scrim substantially retain the structural integrity of the said paper to maintain said paper in compression.Type: GrantFiled: October 24, 1988Date of Patent: July 24, 1990Assignee: The Carborundum CompanyInventors: Douglas J. Bailey, Paul Boymel, Juan M. Cerdan
