Publication number: 20140102898Abstract: A system includes a polymeric housing and a first connector in electrically conductive connection with a first component within the housing. The first connector includes a first extending member formed from a conductive loaded polymeric material. The first extending member is formed such that an interior thereof includes conductive elements within a matrix of the polymeric material so that the interior is electrically conductive and an exterior surface thereof comprises the polymeric material and is less conductive than the conductive interior. The conductive interior of the first extending member is in electrically conductive connection with the first component. The first connector further includes a first extending conductive element in electrical connection with the conductive interior of the first extending member. The first extending conductive element extends from the first extending member to pass through the polymeric housing.Type: ApplicationFiled: December 20, 2013Publication date: April 17, 2014Applicant: MINE SAFETY APPLIANCES COMPANYInventors: MICHAEL ALVIN BROWN, BRIAN KEITH DAVIS, TOWNER BENNET SCHEFFLER

Patent number: 8617364Abstract: An electrochemical sensor includes a polymeric housing and at least a first electrode within the housing. The first electrode includes an electrochemically active surface. The electrochemical sensor further includes a first connector in electrically conductive connection with the first electrode. The first connector includes a first extending member formed from a conductive loaded polymeric material. The first extending member is formed such that an interior thereof comprises conductive elements within a matrix of the polymeric material so that the interior is electrically conductive and an exterior surface thereof comprises the polymeric material and is less conductive than the conductive interior. The conductive interior of the first extending member is in electrically conductive connection with the first electrode. The first connector further includes a first extending conductive element in electrical connection with the conductive interior.Type: GrantFiled: August 29, 2011Date of Patent: December 31, 2013Assignee: Mine Safety Appliances CompanyInventors: Michael Alvin Brown, Brian Keith Davis, Towner Bennet Scheffler

Patent number: 8522418Abstract: A protective helmet includes an outer shell having a generally dome-shaped section and a brim extending outwardly from the dome-shaped section. The dome-shaped section and the brim are formed from a thermoplastic material. The helmet further includes a brim support in operative connection with at least a portion of the brim. The brim support is formed from a material that is more heat resistant than the thermoplastic material. The brim support is sufficiently rigid to limit deformation of the brim upon exposure to high temperature. The brim support material can, for example, have a melting point above 500° F. A method of limiting high-temperature deformation in a helmet includes molding an outer shell of the helmet to consist essentially of thermoplastic material, the outer shell comprising a generally dome-shaped portion and a brim extending outwardly from the dome-shaped section by at least 2.Type: GrantFiled: August 27, 2009Date of Patent: September 3, 2013Assignee: Mine Safety Appliances CompanyInventor: F.
