Abstract: A chilled air distribution system for an aircraft galley service cart, comprising a first plenum on an upper surface of the service cart for directing chilled air over said cart. The cart bay door also includes a pair of diverting curved vanes along a vertical surface to divert air from one surface, such as a front door, to an adjacent surface such as a side wall. The side walls may be provided with a pair of rub strips for guiding air to the rear of the cart, where a return plenum vacuums and recirculates the chilled air back to the first plenum.

Abstract: A gas expansion module for use with semiconductor wafer loadlocks and other regulated-pressure components of semiconductor processing tools is provided. The gas expansion module may be barometrically isolated from the loadlock or other component and pumped down to a vacuum condition while the loadlock is performing operations at a higher pressure, such as ambient atmospheric conditions. After an initial pump-down of the loadlock is performed, the gas expansion module may be fluidly joined to the loadlock volume and the gases within each allowed to reach equilibrium. A further pump-down of the combined volume may be used to bring the loadlock pressure to a desired vacuum condition.

Abstract: The invention relates to an evaporator burner (1; 101) for a mobile heating device, comprising: a combustion chamber (3), a fuel feed line (4) for feeding liquid fuel, and an evaporator for evaporating fed fuel.

A surface structuring (11) with a plurality of depressions (11a) and elevations (11b) is introduced into the fuel preparation surface (6a; 106a) and/or into a support body (6; 106) rear face (6b; 106b) facing away from the fuel preparation surface.

Abstract: The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.

Abstract: An operation knob that includes fin insertion holes formed at both side surfaces of the operation knob, a jig insertion hole formed at a side of the operation knob, and a separation portion formed by separating a part of the jig insertion hole. In the separation portion, a connection portion partially connects an upper facing side and a lower facing side of the connection portion and retains a predetermined clearance therebetween. The first separation surface of the connection portion on the upper facing side and the second separation surface of the connection portion on the lower facing side are contacted with each other, thus even if the connection portion is deformed so that the clearance becomes narrower, a minimum clearance corresponding to a height of the connection portion is retained based on the first separation surface and the second separation surface contacting each other.

Abstract: An air permeable envelope has a gripper for securing the envelope to a seat. A mixture contained in the air permeable envelope can react exothermically upon exposure to air. A sealed bag that is relatively air impermeable, initially holds the air permeable envelope and mixture together with the gripper. Upon opening and unsealing the bag, the mixture is exposed to air in order to start an exothermic reaction. The envelope and the gripper are removed from the bag and the gripper is used to attach the envelope upon the seat to warm it.

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 interior component has a projecting portion projecting rearward at a position forward and downward from a vehicle occupant when the occupant maintains a sitting posture in a passenger compartment. The interior component has a front inclined surface section and a rear inclined surface section in a lower section of the projecting portion. A retainer and air-direction changing members arranged in the retainer are arranged immediately below the projecting portion at positions forward from the front inclined surface section. A manipulating member is arranged above the rear inclined surface section with at least a part of the manipulating member exposed rearward from the projecting portion. A first transmission mechanism and a second transmission mechanism, which transmit movement of the manipulating member to the air-direction changing members, are arranged in the interior component.

Abstract: The invention is a system and method for heliostat mirror control. Here, each heliostat mirror generates a low intensity “signal beam”, directed at an angle off from the heliostat mirror's high intensity and sensor blinding “main beam” of reflected solar energy. The low intensity signal beams may be created by reflecting a small portion of the incident solar light at an angle from the main beam, by reflected artificial light, or from lasers shinning onto mirrors from known locations. The signal beams are detected by optical sensors mounted way from the main heliostat receiver focus, and can be used in a closed loop control system to efficiently ensure that individual heliostat mirrors in a heliostat array accurately track sunlight and direct the sunlight to a central receiver. Because heliostat mirrors need not be taken “off sun” for positioning, the system allows heliostat arrays to be run at high efficiency.

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.
