A secondary air vent valve having an inlet and an outlet is provided. The secondary air vent valve is configured to vent air, but not water, from its outlet. A fluid conduit connects the primary air vent valve outlet with the secondary air vent valve inlet. The second air vent valve provides failsafe air venting upon the failure of the primary air vent valve. A fluid indicator may be provided that indicates the presence of fluid in the conduit. The presence of an appreciable amount of fluid in the conduit is an indication of likely failure of the primary air vent valve.Type: GrantFiled: November 10, 2009Date of Patent: January 28, 2014Assignee: Engineered Corrosion Solutions, LLCInventors: David J. Burkhart, Edward A. Schultz

Patent number: 8622058Abstract: A medical air tubing and anti-mismatch fluid distribution system is provided for preventing the inadvertent connection of a feed line to an incorrect source of fluid. The fluid distribution system includes an adapter that is connected permanently to the fluid supply and has an outlet end that is compatible with a coupling member on the feed line. The coupling member on the feed line is compatible with the adapter but is not compatible with the other coupling member of the second fluid supply. A feed line assembly includes a feed line with a connector fixed to a first end and a nebulizer or other medical device fixed to a second end to form a one piece, integrally formed unit. The second fluid supply can include an adapter that is different from the first adapter so that the coupling members of the feed lines are compatible only with the appropriate adapter for the desired fluid source.Type: GrantFiled: February 22, 2010Date of Patent: January 7, 2014Assignee: Respan Products, Inc.Inventors: Gerhard A. Hacke, Cornel C. Hacke

Publication number: 20130340832Abstract: A valve assembly including a plurality of control systems. A member is included that is actuatable by each of the control systems for controlling operation of the valve assembly. A plurality of tangs is included with at least one tang corresponding to each control system. A plurality of windows each having a shoulder is included, each tang disposed in one of the windows and selectively engagable with the shoulder of the one of the windows. The tangs and the windows are operative together to enable actuation forces to be selectively transferred from any group of selected ones of the control systems to the member via the tangs and the shoulders of corresponding ones of the windows for actuating the member while simultaneously permitting relative movement between the windows and the tangs corresponding to unselected ones of the control systems. A method of operating a valve assembly is also included.Type: ApplicationFiled: June 25, 2012Publication date: December 26, 2013Applicant: BAKER HUGHES INCORPORATEDInventor: Donald Lauderdale

Publication number: 20130293886Abstract: In an arrangement to optically illuminate and/or to perform measurements in a sample stream through a flange which is arranged in the sample stream and closes off a hollow space against the sample stream, there is a continuous loss of material due to abrasion of wall particles, and the flange therefore has to be exchanged on a regular basis. The invention has the purpose of reducing the wear on the flange. To meet this objective, a part of the wall extending along a closed loop around the hollow space (3) consists of an elastomeric body (2.3). This concept makes it possible for the flange or at least for a part of the flange to elastically back away under a concentrated load. Thus, the rate of abrasion of the wall by the sample stream is reduced, because a large part of the incoming energy is converted to heat in the elastomeric body.Type: ApplicationFiled: August 26, 2011Publication date: November 7, 2013Applicant: CARL ZEISS MICROSCOPY GMBHInventors: Nico Correns, Marion Sobe
