Abstract: Apparatuses and methods are provided for protectively covering an air inlet or outlet of an air-moving assembly. The apparatus includes a protective cover assembly, which includes a retractable cover and a spring-biasing mechanism. The retractable cover transitions between a retracted state, when the air-moving assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis. In retracted state, the retractable cover is retracted away from the air inlet or outlet, and in extended state, the retractable cover covers, at least partially, the air inlet or outlet. The spring-biasing mechanism is coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative position within the chassis.

Abstract: An air-circulation promotion apparatus for a vehicle includes a driver's seat and a front passenger seat provided in the vehicle, and a face outlet port of a vehicle air conditioner disposed in front of those seats. A seat outlet port that blows a sucked air from a side surface of a seat back of the seat toward a rear area of the vehicle is disposed in the seat. An air present between the face outlet port and the seat flows rearward of the seat by aid of wind blown out of the seat outlet port. This makes it possible to circulate a comfortable air rearward of the seat to create a vehicle interior environment having no air retention. A circulation fan is provided in the seat and can be integrated with a seat ventilation system or a seat air conditioner.

Abstract: A flow rate controlling system includes: a flow rate balance determining portion that determines a supply flow rate, regulated by a supply air valve, and a common exhaust flow rate, regulated by a common exhaust air valve, so that a difference between the supply flow rate and an exhaust flow rate, regulated by the common exhaust air valve, matches a set point; a valve monitoring portion that monitors the supply air valve, the common exhaust air valve, and a local exhaust air valve; and a flow rate changing portion that issues a flow rate changing instruction to the flow rate balance determining portion. When there is a fault in the supply air valve and/or the common exhaust air valve, the flow rate balance determining portion, upon receipt of the flow rate changing instruction from the flow rate changing portion, changes neither the supply nor common exhaust flow rate.

Abstract: The invention relates to a safety controller for an actuating drive (2.1, 2.2, 2.3) for controlling a gas flow or a liquid flow in an open-loop or closed-loop manner by means of a flap (3.1, 3.2, 3.3) or a valve, in particular in the field of heating, ventilation, and air conditioning (HVAC) systems, fire-protection systems, and/or room protection systems. A safety circuit (9.1, 9.2, 9.3) is implemented to ensure the energy supply in a safety operating mode if an electricity supply circuit (8.1, 8.2, 8.3) drops off or is lost. A control value output circuit (1.1, 1.2, 1.3) detects status signals, in particular signals of a sensor (11.1, 11.2, 11.3), and/or status parameters of a system and/or a specifiable setting of an adjustment device that can be actuated manually. The safety control value is set to one of at least two different control values (SW1, SW2, . . . ) depending on the status signals so that the safety position of the flap is determined adaptively.

Abstract: This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames.

Abstract: An air vent for a vehicle includes a housing extending between an inlet and outlet end. The housing includes a first wall and a second wall that cooperate to define an interior volume therebetween. The inlet end defines an inlet opening and air enters the interior volume through the inlet opening. The outlet end has a length and a width that cooperate to define an outlet opening having a low aspect ratio. Air exits the interior volume through the outlet opening. The first wall includes a directional wall section that extends non-linearly from a transition location to the outlet end. Air travelling through the interior volume is directed by the directional wall section to create a flow direction of air exiting the outlet opening. Vanes may be disposed in the interior volume to allow directability of air exiting the outlet opening, while providing a low pressure drop therethrough.

Abstract: There is provided a method for initiating a sleeve evacuation process in a controlled atmosphere workstation that comprises a chamber, at least one porthole that may be opened for enabling a user to access the chamber, and a sleeve secured to the least one porthole. The method involves placing the hand of a user within the sleeve with the sleeve engaging the forearm of the user, and initiating the sleeve evacuation process in response to the hand and forearm within the sleeve. In an embodiment of the invention the user forms a fist and moves the fist towards the porthole. This creates a pressure increase that can be detected to initiate the evacuation process. Alternatively the user may wear on his or her hand or forearm an element such as a magnetic element or an RFID chip that can be detected at the porthole to begin the evacuation process.
