This invention relates generally to the distribution of a flushing gas during a packaging process. More specifically, the invention relates to an apparatus and method for the distribution of a flushing gas that displaces an undesirable gas from a packaging container during such a process, the apparatus and method optimizing the displacement of the undesirable gas within the container while also minimizing associated equipment costs and cleaning efforts.

A dual path kiln is provided that includes a kiln having at least three chambers including first and second end chambers separated by a central heating chamber. At least two lumber conveyors convey lumber through the kiln in opposite directions. External unidirectional fans are utilized to provide circular directional flows through the lumber. Also provided is a method utilizing the kiln to continuously dry green lumber.

Provided is a device for drying objects that are, for example, moving on a conveyor belt or assembly line. The objects may be container such as, for example, empty or filled can, empty or filled bottles, or non-container objects.

The invention relates to a wall-mountable hand dryer of the type which uses an air-knife to wipe the water from a user's hand. In accordance with the invention, the hand dryer is configured to have a maximum depth, front-to-back, of less than 150 mm when it is surface-mounted onrather than recessed withinthe wall. The dryer has a projecting part which projects outwardly either from the wall or from a rear part of the dryer, and the air-knife is directed downwardly onto the user's hand as it is passed lengthwise underneath the projecting part of the dryer. The air knife is discharged through one or more discharge apertures, and these discharge apertures are positioned towards the front of the projecting part so that they are spaced at least 75 mm from the wall or, as the case may be, the rear part of the dryer.

A hand held appliance, such as a hairdryer, includes a body, a duct, a fluid flow path extending through the duct from a first fluid inlet of the appliance to a first fluid outlet of the appliance. A primary fluid flow path extends from a second fluid inlet through which a primary fluid flow enters the appliance to a second fluid outlet. A fan unit is located in the primary fluid flow path for drawing fluid through the second fluid inlet. A filter is located in the primary fluid flow path. Fluid is drawn through the fluid flow path by fluid emitted from the second fluid outlet. A heater is provided in the body and extends at least partially along and around the duct.

An improved ventilated locker includes a pair of sidewalls and a a back wall connecting the sidewalls. A plurality of compartments is defined between the sidewalls, including at least an upper compartment and a lower compartment. A plenum is disposed adjacent the back wall, the plenum configured for connection to an existing HVAC system. At least one ventilation grille is carried by the back wall in fluid communication with at least one of the plurality of compartments and with the plenum. At least one circulation fan is disposed in one of the plurality of compartments to circulate air from the ventilation grilles through the plurality of compartments.

The invention discloses a wheel cleaning and blowing device, which is composed of four systems: a wheel positioning system, which completes initial positioning of a wheel on a roller bed and finds the position of a valve hole; a wheel advancing and dry-wet conversion system, in which the wheel advances while rotating, thus completing double-station dry-wet conversion of the wheel; a high-pressure water cleaning system, which is matched with the advancing rotating wheel to clean the wheel; and a compressed air blowing system, which is matched with the advancing rotating wheel to blow the wheel uniformly. The invention simultaneously discloses a wheel cleaning and blowing method. By adopting the device and the method, the wheel moves forward all the time during cleaning and blowing, the cycle is short, the efficiency is high, cleaning and blowing are integrated, and dry-wet separation is realized.

An installation has a process chamber defining an inner space having a tunnel-like form defining a receiving region for workpieces. The process chamber has a portal for the supply or discharge of workpieces and has a device for introducing gaseous fluid into the inner space. The device has a nozzle for producing a fluid stream curtain between the portal and the receiving region. A device supplies fresh air introduced into the receiving region at a side of the fluid stream curtain facing away from the portal. The installation has a pivotable guide contour projecting into the inner space and the nozzle or aperture is in the form of a slot which supplies the gaseous fluid to the inner space via the ceiling with a flow direction oblique relative to the floor. The gaseous fluid supplied via the nozzle to the inner space is guided on the guide contour.

A drying device is configured with a sensor corresponding to an air knife-nozzle, and a control switch which suspends an operation of the device when the air knife-nozzle is detected as working abnormally, thereby preventing abnormal products from being produced due to the failure of finding an abnormal condition of the air knife-nozzle in time, ensuring the normal process of the product, and avoiding the nonessential economic loss.

Seal member for a nozzle or an air bar, that is configured and can be positioned to block at least a portion of the flow of air (or gas) exiting or discharged from the nozzle or air bar into the interior of a housing such as a dryer or the like. Each seal member can be actuated externally of the housing interior, without requiring physical access to the housing interior, to move it into air flow blocking relation with a nozzle, and to move it out of air flow blocking relation with a nozzle. Each seal member can be actuated while the apparatus remains in an operating mode. Also disclosed is a method of controlling or regulating the amount of air emitted or discharged from one or more nozzles in a housing by blocking air flow discharged from the one or more nozzles with a seal member.
