Filed:

Mar 12, 2010

Appl. No.:

12/723095

Inventors:

Rosario Sam Calio - Exton PA, US
Jeffrey Churchvara - Downingtown PA, US

Assignee:

Veltek Associates, Inc. - Malvern PA

International Classification:

G08B 21/00

US Classification:

340606, 454187, 7386303

Abstract:

A system for sampling air in a controlled environment that includes two or more air sampling devices at different locations within the controlled environment. A controller is provided at a location outside of the controlled environment and in separate air flow communication with each air sampling devices via separate first vacuum tubes. A ffow switch for each of the air sampling devices is provided at a location between a corresponding air sampling device and the vacuum source, each of the flow switches being configured to separately measure and control the rate of air flow through a corresponding first vacuum tube. An alarm is automatically activated at a location inside the controlled environment by one or more of the flow switches when the rate of air flow measured at one or more of the flow switches deviates from a desired value by a predetermined amount.

Abstract:

A system and method for sampling air in a controlled environment that includes two or more air sampling devices at different locations within the controlled environment. A controller is provided at a location outside of the controlled environment and in separate air flow communication with each of the two or more air sampling devices via separate first vacuum tubes, the controller having a manifold configured to separately control a rate of air flow from the two or more air sampling devices to the controller via each of the separate first vacuum tubes and to selectively direct the air flow from each of the separate first vacuum tubes to one or more second vacuum tubes. A vacuum source is provided at a location outside the controlled environment and in air flow communication with the controller via the one or more second vacuum tubes, the vacuum source providing suction and being controlled by the controller to generate the air flow through each of the first vacuum tubes. And, a flow switch for each of the two or more air sampling devices is provided at a location between a corresponding air sampling device and the vacuum source, each of the flow switches being configured to separately measure and control the rate of air flow through a corresponding first vacuum tube. An alarm is automatically activated at a location inside the controlled environment by one or more of the flow switches when the rate of air flow measured at one or more of the flow switches deviates from a desired value by a predetermined amount.

Veltek Associates, Inc. - Malvern PA

International Classification:

B05B 7/00

US Classification:

222 1, 222394

Abstract:

A method of performing a cleaning operation with an autoclavable bucketless cleaning system is disclosed. The method includes the steps of placing a cleaning solution in an inside of an autoclavable vessel, the vessel having a first connection point and a second connection point disposed at an outside of the vessel, removably connecting an autoclavable outlet regulator assembly on the vessel at the first connection point so as to be in fluid communication with the inside of the vessel, removably connecting an autoclavable inlet regulator assembly on the vessel at the second connection point so as to be in fluid communication with the inside of the vessel, pressurizing the inside of the vessel via the inlet regulator assembly, dispensing cleaning solution from the inside of the vessel via the outlet regulator assembly to clean a designated area, removing any pressurized gas that remains inside the vessel after the designated area is cleaned, removing any cleaning solution that remains inside the vessel after the designated area is cleaned, and autoclaving each of the vessel, the outlet regulator assembly, and the inlet regulator assembly.

International Classification:

G01N 1/20

US Classification:

7386302

Abstract:

A system and method for sampling air in a controlled environment having air sampling devices therewithin. A controller, outside the controlled environment, in separate flow communication with each sampling device via first vacuum tubes, and having a manifold for directing air from the first vacuum tubes to one or more second vacuum tubes. A vacuum source outside the controlled environment, in flow communication with the controller via the second vacuum tube(s), providing suction, and being controlled by the controller to generate flow through the first vacuum tubes. A flow switch between each sampling device and the vacuum source, for measuring and controlling the flow rate through a corresponding first vacuum tube. An alarm inside the controlled environment, is activated by a flow switch when the corresponding flow rate deviates from a desired value by a predetermined amount.

Abstract:

A washing system that includes a vessel for storing a cleaning solution, an inlet connection point for pressurizing the vessel, and an outlet connection point for dispensing the cleaning solution. In one embodiment, the washing system includes a regulator valve configured to remain open and allow the inside of the vessel to be filled with pressurized gas via the inlet connection point when pressure inside the vessel is below a predetermined value and automatically close when pressure inside the vessel exceeds the predetermined value. In another embodiment, the washing system includes a relief valve (e.g., at the top of the vessel) that is configured to remain closed when pressure inside the vessel is below a predetermined value and automatically open when pressure inside the vessel exceeds the predetermined value.
