Patent number: 9239405Abstract: A particle detection system is provided, including a sensing chamber having an inlet nozzle, an outlet nozzle, and an interrogation zone defined therebetween. Particles in a sampled environmental gas are prevented from escaping the interrogation zone by pressurizing the sensing chamber such that the pressure therein is higher than that in the outlet nozzle. This is accomplished by providing a source of extra gas to the sensing chamber, for example, by diverting gas from an inlet flow path directly to the sensing chamber.Type: GrantFiled: March 15, 2013Date of Patent: January 19, 2016Assignee: AZBIL CORPORATIONInventors: John H.

Publication number: 20150362109Abstract: A tube connection assembly having an elastomeric tube defining a fluid channel therethrough, and a retention sleeve, composed of a cross-linked PEX material having memory retention properties, disposed around the distal portion of tube device. Prior to partial assembly, the retention sleeve is expanded about 15% to about 50% from an unexpanded natural condition to an expanded condition, enabling placement onto the tube device. The tube distal portion and disposed retention sleeve can then be connected to a barbed male portion of a connector fitting, where the sleeve will radially retract back toward the natural condition, generating significant, radially uniform, hoop forces around the tube distal portion for fluid tight mounting to the connector fitting.Type: ApplicationFiled: June 12, 2014Publication date: December 17, 2015Inventor: Bradley H.
