20080209751	Dryer exhaust duct alarm - A dryer exhaust duct alarm detects the presence of lint or other obstructions in an exhaust duct or vent. A thin lever is suspended within the duct and is slightly cupped in shape to more effectively capture air flow. In the presence of uninhibited air flow, the lever is substantially displaced from its initial substantially-vertical position toward a substantially horizontal position. But when airflow is inhibited, the lever is not sufficiently displaced. A detector detects operation of the dryer. If the dryer operates for a determined period of time but the lever is not sufficiently displaced, the user is alerted of the problem. Other data may also be presented to the user, including real-time data over a communication medium.	09-04-2008

20100270335	Syringe with Improved Plunger - A plunger for a syringe used to inject gas and liquid chromatography samples has an end portion surrounded by a flexible sleeve. The sleeve forms a seal in the bore of a barrel traversed by the plunger, the bore being in fluid communication with a cannula attached to the end of the barrel. The plunger has an end surface that is exposed and is flush with an annular end surface of the sleeve. The plunger end surface, and not the sleeve, contacts the cannula upon injection and avoids imposing cyclical hoop stresses on the barrel which tend to crack the barrel after a finite number of cycles. In a further embodiment, a thin layer of sleeve material covers the end surface of the plunger. The thin layer avoids inducing significant barrel stress.	10-28-2010

20120240661	RESTRICTED LINE OF SIGHT DESIGN FOR INLET LINER - An inlet liner is provided for use in an inlet assembly of a chromatograph system. The inlet liner has an elongate tube that extends along a longitudinal axis and defines a bore that extends along the longitudinal axis and has an inner bore surface. At least one projection extends from the inner bore surface into the bore. Chromatograph systems are provided including the exemplary inlet liner(s). Methods are also provided for analyzing a sample containing a matrix in a chromatograph system having an inlet assembly connected to a chromatograph column. The method includes positioning an exemplary inlet liner in the inlet assembly, flowing the sample through the inlet liner, and adhering a portion of the matrix to a projection surface of at least one projection of the inlet liner.	09-27-2012
