摘要:
The present invention relates to a sealed and ventilated receptacle for storing equipment, such as firefighter turnout gear, that generally includes a base, at least one sidewall extending from the base, and a top wall that covers the opposite end of the sidewall. A sealable door may be positioned on the sidewall to access the inside of the receptacle and to prevent any contaminants from exiting the receptacle. The receptacle may also include an intake fan and exhaust fan that are each connected to a duct for providing fresh air to and removing contaminated air from the inside of the receptacle. The receptacle may further include a temperature control unit for regulating the temperature inside of the receptacle. Additionally, a hook for hanging a firefighter coat, trousers, or other items may also be included on the inside of the receptacle.

Disclosed is a work booth safety system for an automotive body repair shop including a work booth with a ventilation system for evacuation of polluted air and an entrance closed or opened by a door or drape. The work booth is configurable into three different work modes: 1) For preparative dent repair, the entrance is kept open and electrical sockets and compressed air supply is deactivated. Ventilation air flow is mainly directed in a horizontal direction and evacuated through a wall ventilation outlet duct. 2) For spray application of a body sanding foundation, the entrance is closed and electrical sockets are deactivated, the compressed air supply is activated, and the ventilation air flow matches that of work mode 1. 3) For welding, the entrance is closed and electrical sockets are activated. The compressed air supply is deactivated and the ventilation air flows vertically upward through a roof ventilation outlet duct.

The present disclosure relates generally to fume hoods, and more particularly to systems and methods for controlling a fume hood airflow using an image (e.g., an optical image, an acoustic image, etc.) of a fume hood opening. A system for controlling a fume hood may include an image capture sensor, a configurator and a controller. The image capture sensor may be positioned to have a field of view that includes at least a portion of a fume hood opening, and may be configured to capture an image that includes at least part of the fume hood opening and/or a person working at the hood. The controller may then provide a control signal to a ventilation device for providing a desired airflow in the fume hood. The control signal may depending on the current size of the fume hood opening as captured by the image capture sensor.

Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described.

A room pressure controlling system having a local exhaust valve, a supply air valve, a common exhaust air valve, controllers and a differential pressure sensor. The controller calculates a correction control output value for the valve operated as the room pressure controlling valve, which is either the supply air valve or the common exhaust air valve, based on a setting value and a room pressure measured by the differential pressure sensor. The controller evaluates whether or not the supply airflow rate and/or the exhaust airflow rate is changing, and if an airflow rate is changing, emphasizes rapid responsiveness of the room pressure control than a reduction in the frequency of actuation of the room pressure controlling valve, if the airflow rate is stable, the controller emphasizes the reduction in the frequency of actuation of the room pressure controlling valve than the rapid responsiveness of the room pressure control.
摘要:
A medium strength, liquid solvent, spray brush station system gently cleans surfaces of components during nano- and microtronics processing in cleanroom facilities. This system includes intermediate strength, yet effective surface cleaning with minimal damage to subject nano and microtronics components. Moreover, the instrument is compatible with a cleanroom environment, and provides self contained, easily manageable disposition of the peripheral mess and waste resulting from the cleaning process.

A controlled atmosphere workstation comprising a transparent housing (1) having a pair of apertures (21, 22) through which can be inserted the hands of a user. The chamber has a forward part defined at least in part by a pair of opposed side wall portions (7, 10) which converge towards the front of the chamber, in which the apertures are provided. There is a font panel (3) and an upwardly inclined top viewing panel (13). The housing is mounted on a base (2) and contains a gas circulation system which directs filtered gas onto the side walls of the chamber on both sides, and then re-circulates the gas into a gas circulation chamber provided with fans (31, 32) on either side, feeding outlets (27, 28).
摘要:
An apparatus for treating the surface of a microelectronic workpiece via impingement of the surface with at least one fluid and a method for operating the apparatus are described. In particular, the apparatus includes a treatment chamber defining an interior space to treat the microelectronic workpiece with at least one fluid within the treatment chamber, and a movable chuck that supports the workpiece within the treatment chamber. The apparatus further includes a workpiece translational drive system configured to translate the movable chuck between a workpiece load position and at least one processing position at which the workpiece is treated with the at least one fluid using at least one nozzle connected to at least one fluid supply, and a workpiece rotational drive system configured to rotate the microelectronic workpiece.
