Patent number: 5622538Abstract: A source capture system for capturing contaminated air from an industrial process includes structure both for continuously capturing a contaminated air volume emitted during operation of the industrial process and for mixing that contaminated air volume with an ambient air volume to produce a mixed air volume which is then transferred to an air clean apparatus or the like. The source capture system recognizes that air volumes will exhibit different characteristics traveling through an air treatment system, and that certain of those characteristics such as cloud-like formation and contaminated air volumes having significant gaseous phase vapor components are undesirable and operate to decrease the overall effectiveness of the air treatment system, regardless of what type of technology is used for the air cleaning apparatus.Type: GrantFiled: March 28, 1995Date of Patent: April 22, 1997Assignee: Helical Dynamics, Inc.Inventor: Wolodymyr Diachuk

Patent number: 5613990Abstract: An air cleaning system for treating contaminated air from a mechanical industrial process containing a heterogenous multi-component mixed density fluid (e.g., mist, vapor and/or smoke) that addresses the cloud-like behavior of this contaminated air. The air cleaning system continuously captures a contaminated air volume emitted during operation of the mechanical industrial process and mixes that contaminated air volume with an ambient air volume in order to produce a mixed air volume having certain characteristic temperatures and air velocities. The characteristics of the mixed air volume are controlled such that the mixed air volume does not exhibit cloud-like behavior when transferred via a conduit structure to an air cleaning apparatus or the like.Type: GrantFiled: March 28, 1995Date of Patent: March 25, 1997Assignee: Helical Dynamics, Inc.Inventor: Wolodymyr Diachuk

Patent number: 5601625Abstract: A process and device for removing heavy metals and compounds containing heavy metals from waste gas of a metallurgical vessel which is charged with materials posing disposal problems. The flue gas collecting in the metallurgical vessel is sucked out of the vessel as a main gas flow and cleaned in a gas cleaning system. The flow of cleaned gas is guided to an after-burning device. A portion of the clean flue gas is diverted frown the main gas flow leading to the after-burning device. The diverted flow portion is cooled and guided back to the main flow of flue gas where it is mixed with the flue gas before the main flow of flue gas enters the gas cleaning system.Type: GrantFiled: December 7, 1994Date of Patent: February 11, 1997Assignee: Mannesmann AktiengesellschaftInventor: Klaus H.

Patent number: 5597385Abstract: An exhaust system, including a hand-held exhaust wand is employed to remove laser smoke plumes generated at a surgical site. The wand includes a transparent cylindrical shroud containing a conical filter that diverges in the proximal direction. An adapter, removably coupled to the shroud at its proximal end, enables coupling of the wand to standard vacuum tubing, connectors and other components for exhausting air that flows through the wand. The wand is positioned with its distal end confronting the surgical site, whereby plumes and odor generated at the site are immediately drawn into the wand through its distal opening. As air passes through the filter toward a proximal opening of the wand, the conical filter traps the airborne contaminants to protect against contamination of downstream components. The removable coupling of the shroud enables convenient exchange of the filter.Type: GrantFiled: November 21, 1994Date of Patent: January 28, 1997Assignee: Moerke Custom Products, Inc.Inventor: Duane C.

Patent number: 5409511Abstract: A centralized system for removing the plume resulting from laser surgery, electrocauterization or orthopaedic surgery that takes advantage of the articulating arms frequently found in medical procedure rooms. The plume is drawn away from the surgery location by a vacuum. The tubing that carries the plume is held near the location of the medical procedure, and the plume is then drawn into the tubing. The tubing leads through the articulating arm to a main located above the ceiling. The main leads to a central room that includes, in series, a centrifugal separator, a vacuum producer and a high efficiency air filter.Type: GrantFiled: November 23, 1993Date of Patent: April 25, 1995Assignee: Michaud, Cooley, Erickson & Associates, Inc.Inventor: Gwen A.

Patent number: 4339250Abstract: An air filter arrangement for cleaning the ambient air in enclosed air spaces. Granular activated carbon and two particulate air filters provide the actual air filtration media to remove both gaseous and particulate air impurities. The structure of the air filter retains the particulate filters in position by friction. One of the particulate filters is placed between the granular activated carbon and the air filter metal retaining screen without intervening support or protection from the activated carbon. A fountain of fresh air is provided by directing the exhaust of the air blower toward the ceiling of the room thereby creating a low pressure area surrounding the air filter near the floor. Dirty air near the floor migrates toward the low pressure area and enters the air filter where it is cleaned. The remaining dirty air in the room sinks as a pool mass slowly toward the floor where it eventually enters the filter.Type: GrantFiled: July 17, 1980Date of Patent: July 13, 1982Inventor: Timothy T.
