An air manager for the containment of hazardous fumes over a liquid chemical tank in exhausted equipment and systems in a clean room. A powered, filtered airflow source forces filtered air through a plenum coextensive with a transverse dimension of the chemical tank, in a sheet-like airflow stream over the liquid surface. The airflow is captured at the opposite side of the liquid chemical tank and directed to a powered exhaust. The air manager works cooperatively with the clean room laminar airflow, dramatically increasing the efficiency of the local exhaust. Critical Capture Velocity over the entire surface of the tank is maintained, assuring complete containment of chemical fumes. Optional airflow guides positioned along the sides of the chemical tank may be employed to confine the air stream to the area over the liquid surface.

The invention discloses an electronic cigarette with an ultrasonic atomization function and tobacco liquid. An ultrasonic liquid atomization mode is set, and compared with general liquid heating atomization, the atomization rate of ultrasonic atomization is improved. Especially, the tobacco liquid is automatically sucked out of a tobacco liquid storage bin through a liquid level adjuster to be atomized by an ultrasonic atomizer, and compared with a current fiber absorption mode and the like, liquid waste is avoided, and meanwhile it can be guaranteed that airflow is sufficient after atomization. Meanwhile, due to the fact that the tobacco liquid directly enters the ultrasonic atomizer, the atomization rate can be further improved, atomization components can be even relatively, and the taste of a smoker can be proper. In addition, high-concentration propylene glycol and glycerin components are removed from the components of the tobacco liquid, and the taste of the smoker can be more comfortable.

A facemask for skiing, snowboarding, and other winter sports integrates with traditional goggles by use of a temple-trough system that secures the goggle headband and places the goggle headband on top the facemask headband. Diffusing foam circumscribing voids at the cheek areas provides even ventilation and prevents over chilling of the cheeks. Foam at the perimeter of the mask and at the nose bridge area keep the mask off the user's mouth and nose tip. The design at the jaw region allows movement of the head and the use of a jacket collar or scarf. In an alternative embodiment, a bridge-flare system at the nose area allows the mask to conform to a wide variety of nose sizes and shapes.

A tractor has a log splitter installed on two loader arms pivoted at a front end of the tractor. The log splitter includes a frame for attachment to the loader arms. The frame includes a surface, to which a ram and a wedge are coupled. An actuator mounted to the frame moves the ram and / or the wedge to split a log received between the ram and the wedge. The wedge includes a main blade and a cross blade perpendicular to the main blade. An edge of the cross blade is offset from an edge of the main blade so as to reduce the force required to achieve a four-way split of the log. The wedge and the frame are designed to enable inverting the log splitter to grasp a log, then raising the inverted log splitter to split the log directly into a truck bed. The uniquely designed hydraulic tank—ballast box combination provides an owner an external high volume hydraulic system without impeding the capability of the tractor hydraulic system. The tank and ballast box hitch assembly can also integrate the pump mounted to the hitch frame allows one to remove all components together.

An equipment rack including front and back doors is configured with fans for air cooling enclosed electronic devices in both doors. The fans in each door are sufficient, by themselves, to provide sufficient airflow to cool the electronic devices. The two doors include switches and magnetic interlocks configured such that when one door is opened, the magnetic interlock on the other door is activated preventing both doors from being opened at the same time. This ensures that at least one door is always closed while the system is powered up, and since the fans in each door provide sufficient cooling for the equipment rack, the rack is always sufficiently cooled to prevent electronic device failure from overheating.

An aerial plant planter comprising a wall and a flat bottom surface that formed the cavity for holding root structure of a plant and its growing medium with attached individual porous water chambers on the wall of the planter for storing quantity of water. Open spaces are created around the wall and bottom of the planter to provide sufficient airflow. Tops of the water chambers are open to supply humidity to the plants and for easy refilling. The flat bottom defines a plurality of risers for maximum air circulation and to prevent the plant from sitting on any excess water that may be present underneath the planter.

A method is provided to control a drivetrain of a vehicle, especially a utility vehicle, wherein the drivetrain includes an engine with a cooling system. The cooling system includes a fan. The cooling system and the drivetrain are controlled by an electronic control unit (ECU). The ECU has access to a navigation system with topographic data. The method includes determining a topology of an upcoming route of the vehicle, estimating the load of the engine dependent of the topology of the upcoming route, estimating a temperature variation of the cooling system during the upcoming route, and controlling the drivetrain dependent on the estimated temperature variation, such that an actual temperature of the cooling system is kept below a temperature threshold value during the upcoming route of the vehicle. The temperature threshold value is dependent on a temperature at which said fan is activated.

A wad of cotton is provided in the lower open end of the capsule.

A respiratory assisting device comprising of an expandable bag which has a bilayer that can be inflated in order to give the bag a rigid and predetermined shape. The bag can then be compressed in order to displace inspiratory gas that is in the inner cavity and deliver it to the patient. The bag includes a one-way valve that passes through the bilayer allowing the inner cavity of the bag to fill with ambient air when the air within the cavity has been expended. The bag portion is connected to an air-tight hollow wall prism shape enclosure via a T-connector piece. This t-shaped connecting piece allows the air to pass through two manifold chambers that attach to another t-shaped connecting piece. One of the manifolds contains a pressure-release valve feature on the outer wall which vents air from the bag to the periphery if pressures within the system exceed a target pressure. The second t-connector piece has a two-way valve system within its walls to deliver the inspiratory air from the bag to inflate the patient's lungs while preventing exhaled air from the patient from entering back into the bag. Instead this expiratory air is vented into the periphery. Below the valve is a protective filter which serves as a safety mechanism to prevent the transmittance of any potentially dislodged components from within the device from being transferred down into the victim's airway. The air finally flows through a collapsible mask which can be inflated when needed to give it a rigid shape that conforms to the patient's face with the purpose of delivering and receiving rescue breaths. The t-shaped connector pieces are rotatable which permits the two inflatable portions of the device,the bag and the mask, to fold into the interior of section of the manifold enclosure for storage and transportation purposes.
