20090170418 | CONTROLLED ENVIRONMENT CABINET - A controlled environment cabinet comprises a working chamber made up of clear panels and a stainless steel frame. Two frontal panels may be raised on hinges to access an interior of the chamber. Working armports are provided, closed by a flexible membrane, which is slit such that an operator may pass an arm into the chamber, but the membrane closes around the arm, restricting airflow out of the chamber. An air treatment unit is supplied with air from the chamber by a fan/filter unit. The air treatment unit can raise or lower the temperature and relative humidity of the air, and the fan/filter unit contains a HEPA filter to remove particulates suspended in the air. The treated air is passed back to the chamber. Controls are provided, whereby a desired temperature, humidity and air flow rate or rate of atmosphere exchange within the chamber may be set. | 07-02-2009 |

20090215377 | Low Pressure Blow-Off Assemblies and Related Methods - A low pressure blow-off assembly provides converging airflow around a length of material moving through the assembly. The assembly generally includes a body having an interior wall and an exterior wall. The interior wall defines a bore extending through the body for receiving the material through the body, and the exterior wall surrounds the interior wall and defines an air reservoir within the body generally between the exterior wall and interior wall. A cap is configured to be coupled to the body to cover at least part of the air reservoir. The bore includes a generally tapered end and the cap includes a generally tapered inner lip, where the tapered end of the bore and the tapered inner lip of the cap define an opening therebetween for discharging air from the air reservoir through the opening in a generally converging airflow pattern around the material passing through the body. | 08-27-2009 |
20100075586 | Systems and methods of preparing wheel surfaces and maintaining air circulation in a mobile environment - An integrated system of preparing wheel surfaces and maintaining air circulation in a mobile enclosure is provided. The system could include a first compartment having a wheel rotating apparatus configured to rotate a wheel about an axis. The system could also include an air circulation system to filter pollutants from the outside environment before drawing air into the mobile enclosure. The air circulation system could also filter pollutants inside the mobile enclosure before releasing air outside of the mobile enclosure through an opening disposed on the floor of the mobile enclosure. | 03-25-2010 |
20100075587 | APPARATUS HAVING A CLOSED-OFF WORK CHAMBER WITH IMPROVED CLEANABILITY - The invention relates to an apparatus, in particular for processing toxic and/or medical media, including a closed-off work chamber, in which the medium can be manipulated. A ventilating device delivers a particle-free or laminar or turbulent air stream to the work chamber. A return air conduit communicates with the work chamber via an outlet opening and by way of which air is carried away from the work chamber. A cleaning element is disposed in the work chamber, to enable cleaning of the work chamber and of the return air conduit. At least one blocking device blocks off an additional connecting portion between the work chamber and the return air conduit. The blocking device is able to be opened for cleaning of the return air conduit. | 03-25-2010 |
20100081368 | MOBILE LAMINAR FLOW HOOD FOR USE IN PODIATRY - A mobile laminar flow hood specifically devised for use in podiatry and a podiatric apparatus to which such hood is associated are described. The hood is adapted to generate a laminar flow of sterile air. In particular, an apparatus comprising a system for the generation and treatment of a laminar air flow in a intervention zone is described, together with means to support the system for the generation and treatment of a laminar air flow. The system comprises a blowing hood adapted to generate a laminar flow of sterile air towards said intervention zone, and a suctioning hood adapted to suck the laminar flow of sterile air from the intervention zone. | 04-01-2010 |
20100323600 | CHAMBER FACILITY, ROBOT CELL INCLUDING CHAMBER FACILITY, AND CHAMBER VENTILATING METHOD - A chamber facility includes: an air supply unit which supplies clean air to the inside of a chamber; an air supply port section which has one end communicating with the air supply unit and the other end opened into the chamber; and an air exhaust unit which exhausts air within the chamber from an exhaust port formed at a lower position of the chamber, wherein the air supply port section has a plurality of air supply port units which generate rotational flow around a vertical axis within the chamber. | 12-23-2010 |
20110183594 | Plasma cutting machine exhaust apparatus and method - An exhaust system for a plasma cutting machine which uses an outside air supply to provide needed airflow to a cutting table thereof is disclosed. Airflow into the cutting table may be controlled and directed to select zones of the cutting table. | 07-28-2011 |
20120094589 | AIR DEFLECTOR AND METHOD FOR MOUNTING AN AIR DEFLECTOR - An air deflector of an extractor hood, wherein the air deflector has two components to divert air, which is extracted from a chamber by the extractor hood back into the chamber. The air deflector also has a plug connector to connect the two components to each other in a detachable or non-detachable manner. | 04-19-2012 |
