Patent number: 11125390Abstract: The present invention relates to containers and packaging materials, and more particularly to a container having a thermal barrier member for reducing the transfer of heat from and/or to the container. The shipping container preferably comprises an outer vessel with an O-ring and an inner vessel separated by an air gap. The inner vessel has a first and second wall and a lid assembly. The lid assembly has a top lid and a bottom lid and a thermal paste. A felt gasket is preferably positioned between the lid assembly and the first and second walls. The first and second walls comprise at least two relief valves. One relief valve is a Flame Arresting/Smoke Particulate Filtration/Chemical Adsorption Unit Assembly and the valve is bi-directional. The thermal paste is preferably a flowable polymer based heat-absorbing material. The shipping container is stackable on a registration plate with other containers.Type: GrantFiled: August 25, 2017Date of Patent: September 21, 2021Inventors: Carl Gehlhausen, Daniel Gehlhausen, Dennis Campbell, Von R Walters

Patent number: 10584829Abstract: A shipping container for shipping thermally active materials includes a plurality of structural panels that define a container interior, and are configured for receiving the thermally active materials. The container also includes an exterior disposed adjacent to an environment in which the shipping container is disposed. A thermal barrier member is placeable between the thermally active materials and the environment in which the container is placed. The thermal barrier includes a thermal barrier interior panel and a thermal barrier external panel defining a heat absorbing material receiving cavity. A flowable polymer based heat absorbing material is disposed within the heat absorbing material receiving cavity. The thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed.Type: GrantFiled: February 7, 2017Date of Patent: March 10, 2020Assignee: Nochar, Inc.Inventors: Carl Gehlhausen, Dennis Campbell, Daniel Gehlhausen

Patent number: 9119038Abstract: The present disclosure describes systems and methods for time-based geolocation queries, with designated planned arrival and/or departure times or event start/end times. The number of queries can be drastically reduced to reduce battery, bandwidth, and processing requirements; or the rate of queries can be increased within a specified time frame, providing much higher resolution of geolocation information. Geolocation information may be monitored via notifications from portable devices to identify demographics of users within identified regions and subregions, allowing real-time, dynamic comparison of demographic information between locations, such as restaurants, clubs, or events.Type: GrantFiled: May 21, 2013Date of Patent: August 25, 2015Assignee: Yopima LLCInventors: Vernell Woods, Dennis Campbell, Troy Nunnally, Travis Nunnally, Alexander Mims

Publication number: 20080124498Abstract: A method for producing fluorescent markings on a substrate which method comprises exposing a composition comprising a polymer and an organic pigment to a heat source, such as laser radiation, to produce a fluorescent markings which are not discernable when viewed under ambient visible light but readily apparent under UV light is disclosed. The method produces novel compositions wherein a fluorescent form of a pigment is present at a higher concentration in defined domains relative to the remainder of the composition. The novel polymer composition is particularly useful in security marking applications.Type: ApplicationFiled: October 30, 2007Publication date: May 29, 2008Inventors: Damien Thurber Cole, Joseph E.

Patent number: 5783723Abstract: Dialkyl succinylsuccinates are prepared in a pure form and in high yield by reacting an alkali metal alcoholate with an excess of dialkyl succinate under anhydrous conditions followed by isolation of the di(alkali metal) salt of the dialkyl succinylsuccinate and then neutralization of the salt with acid. The resulting dialkyl succinylsuccinate is isolated or used without isolation as an intermediate in the production of quinacridone pigments. The disclosed process provides for high yields and reduced organic waste compared with known processes.Type: GrantFiled: September 24, 1996Date of Patent: July 21, 1998Assignee: Ciba Specialty Chemicals CorporationInventors: Colin Dennis Campbell, Damien Thurber Cole, Harold Raymond Taylor, III
