An exhaust hood may have an exhaust inlet; a shroud having a lower edge and being movable, the shroud being configured to define an enclosed space over and adjacent a cooking surface, the enclosed space being in communication with the exhaust inlet. The shroud is movable to a first position providing clearance between the cooking surface and the shroud lower edge and a second position providing substantially less than the clearance provided by the first position. A vertical jet at the lower edge is aimed upwardly and along an inside of the shroud when the shroud is in the second position and the vertical jet is in the enclosed space. A horizontal jet is provided at a top of the shroud and aimed along an inside of the shroud when the shroud is in the second position and the vertical jet being in the enclosed space.

An abort gate to divert airflow in an air system comprises a housing having a flow inlet, a primary outlet, and a secondary outlet. A flow diverting blade is mounted to a shaft within said housing. Rotating a blade arming bar also rotates the flow diverting blade within said housing between a first position and a second position. A pulley bar mounted to the shaft adjacent to the blade arming bar comprises a pulley bar pulley that receives a cable that connects said pulley bar to a winch and a tab on the pulley bar that extends towards the blade arming bar, such that rotation of the pulley bar toward the blade arming bar causes the tab to push said blade arming bar and also rotate the blade arming bar thereby rotating said flow diverting blade.

A sash system includes a sash, a counter-weight coupled to the sash by a coupling member, a locking mechanism coupled to at least one of the sash and the coupling member, and a controller coupled to the locking mechanism. The locking mechanism is transitionable between an open configuration where the locking mechanism does not inhibit movement of at least one of the sash and the coupling member, and a locked configuration where the locking mechanism inhibits movement of the at least one of the sash and the coupling member. The controller is configured to control operation of the locking mechanism to selectively transition between the open configuration and the locked configuration based on a condition of the sash. The sash and the counter-weight are configured such that when the locking mechanism is in the open configuration, the sash lowers due to gravity.

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.

Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which autonomously decontaminate parts. Parts to be cleaned are identified, and based on the identification of the part, a part specific cleaning program is initiated. During the cleaning, the part is manipulated about a gas supply in such a way that the drag force on the contamination particles attached to the part exceeds the contamination particles' surface adhesion force and accordingly is removed from the surface of the part. The removed contamination is then evacuated from the atmospheric environment near the part by a low pressure zone of a second gaseous material near the part.

In one embodiment, a fume hood equipment support system may include a platform having a plurality of vertical air channels therethrough, support legs configured to hold the platform above the work surface of a fume hood, and an air chamber formed beneath the platform. The platform may include a lattice of interconnected horizontal slats forming a plurality of vertical air channels through the platform. The platform may have sidewall surfaces, an upper surface and a lower surface. The support legs may be attached to the platform to hold the platform above the work surface of fume hood. The work surface and the lower surface of the platform may form the air chamber beneath the platform. The air chamber may be in fluid communication with the vertical air channels. The sidewall surfaces, the upper surface and the lower surface may together define a bulk volume of the platform, the bulk volume having void space defined by the vertical air channels. In on example, the bulk volume comprises at least 50% void space.

The present invention relates to a scaled 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.

The constructive assembly of the containment means (9) is intended for the automated production of pharmaceutical or biotechnical articles (6). As an end product, a respective article (6) comprises multiple article parts (7). The containment means (9) has a housing (90) within which there is an inner chamber (91) having at least one through opening (917, 919). At most, multiple robots (1, 2) are installed in the chamber (91), which generally have a manipulating element (12, 22) on the pivotable arms (11, 21) thereof, which can move within a pivot range (R.sub.1,R.sub.2). At most, multiple process units (3) are installed in the chamber (91) for the production of the articles (6). The chamber (91) is formed by a process space (93) for the production of the articles (6) and a tub-shaped base space (92) for anchoring the feet (10, 20) of the robots (1, 2) to the side surfaces (910,912,916,918) inside the base space (92). The process space (93) is arranged above the base space (92) and both are adjacent in a corresponding manner and such that they are open to one another. The manipulating element (12, 22) functions as a gripping means and transportation means for the articles (6) or article parts (7) and/or for inspecting the articles (6) or article parts (7) and/or for the production of the articles (6). The pivot range (R.sub.1,R.sub.2) of the manipulating elements (12, 22) on the robots (1, 2) extends in the horizontal and vertical plane within a working region (a), which lies between a minimum and a maximum working height (a.sub.min,a.sub.max).

A lab processing device is provided. The device may include a container with an open side, a sash located on the open side and an airflow sensor to measure airflow to or from the interior volume of the container. The device can include a light source configured to be enabled or disabled depending on the location of the sash or measurements of the airflow sensor.

An air replenishing fume hood includes a cabinet, a door set, an air replenishing unit and an air guiding unit. The cabinet has an inner casing defining an operating chamber and having an air inlet and an air outlet. A side of the cabinet includes an operation window. A first air passage is formed between the inner casing and the cabinet. The door set includes an outer door leaf adapted to open or close the operation window, and an inner door leaf adapted to open or close the air inlet. An end of the air replenishing unit extends into an external space via an outdoor tube, and another end of the air replenishing unit is connected to the first air passage via an extension tube. The air guiding unit includes an end connected to the air outlet, and another end extending into the external space or a collection tank.
