Patent number: 9937366Abstract: A compact ignition system for chemical oxygen generators for possible use in an aircraft. The chemical oxygen generator is configured such that a majority of the ignition system can be accommodated within an interior of the generator body. In some embodiments, the ignition system is positioned within a recess of an upper surface of the core of the generator. Housing a majority of the ignition system within the generator allows the overall oxygen-generating capacity of the generator to be increased without requiring a corresponding increase in the overall length of the generator.Type: GrantFiled: October 10, 2014Date of Patent: April 10, 2018Assignee: AVOX Systems Inc.Inventors: William A. Mack, Jr., William A. Donofrio, Dean A. Kubik, Yelena Aleshina

Patent number: 4647755Abstract: A portable hairsetter appliance for heating a single hair roller. The hairsetter comprises a cylindrical housing having an axially aligned and longitudinally extending high voltage electric resistance heating element encapsulated in a quartz envelope for heating a single hair roller inserted into the cylindrical housing. The weight of the roller closes an electrical circuit and the roller is heated to a predetermined temperature whereupon a thermoplastic bimetallic disc changes its concavity to open the electrical circuit. A safety means is provided to automatically open the electrical circuit if the roller is pressed into the housing with a force greater than its own weight.Type: GrantFiled: April 15, 1985Date of Patent: March 3, 1987Assignee: Clairol IncorporatedInventor: William Mack
