    • An industrial oven in which articles to be heat treated are carried by a conveyor through a heated tunnel space in a tunnel structure which has end walls with access openings, such oven comprising a nozzle directed downwardly into the tunnel space at an inclined angle across at least one access opening, an exhaust opening communicating with the tunnel space in the vicinity of the upper portion of such access opening, and air handling means for withdrawing hot air from the tunnel space through said exhaust opening while blowing hot air into the tunnel space through said nozzle for minimizing the escape of hot air through such access opening. The air handling means may take the form of a recirculating blower connected between the exhaust opening and the nozzle. The oven may have an air heating and recirculating system which withdraws air from the tunnel space. Instead of providing a separate recirculating blower, exhaust and supply ducts may be connected to the intake and discharge sides of such system and may extend to the exhaust opening and the nozzle to circulate hot air out of the tunnel space through the exhaust opening and into the tunnel space through the nozzle.
    • 一种工业烤箱,其中要被热处理的物品通过输送机通过隧道结构中的加热隧道空间承载,该隧道结构具有带有进入开口的端壁,这种烘箱包括至少以倾斜角度向下指向隧道空间的喷嘴 一个进入开口,与该入口的上部附近的隧道空间连通的排气口,以及空气处理装置,用于通过所述排气口从隧道空间排出热空气,同时通过所述排气口将热空气吹入隧道空间 喷嘴,用于最小化热空气通过这种进入开口的逸出。 空气处理装置可以采用连接在排气口和喷嘴之间的再循环鼓风机的形式。 烤箱可以具有从隧道空间抽出空气的空气加热和再循环系统。 除了提供单独的循环鼓风机之外,排气和供应管道可以连接到这种系统的进气和排出侧面,并且可以延伸到排气口和喷嘴,以使热空气通过排气口从隧道空间流出,并进入 通过喷嘴的隧道空间。

    • An industrial oven for heat treating a series of articles by transporting the articles through a heated tunnel in an enclosure, the enclosure having air barrier closures at the entrance and exit of the tunnel, the air barrier closure at the entrance of the tunnel having a blower with an inlet for receiving a gaseous medium and a nozzle for expelling the gaseous medium in a flow and directing the medium flow across the tunnel, the blower having a heater adapted to raise the temperature of the gaseous medium expelled through the nozzle above the temperature within the tunnel, the enclosure also having an exhaust port between the air barrier closures and an exhaust blower for removing a portion of the gaseous medium from within the tunnel and reducing the pressure of the gaseous medium within the tunnel to a pressure below that of the ambient atmosphere. Also the method of heat treating process articles in such an oven in which the gaseous medium of the air barrier closure at the entrance of the oven is heated to a temperature above that of the oven. Also the method of heat treating process articles in such an oven in which the gaseous medium of the air barrier closure at the entrance of the oven is provided with moisture, and further the method of curing process articles coated with powdered paint in an oven provided with an air barrier closure at the entrance to the oven in which the gasses in the closure are heated to a temperature above that of the oven and provided with moisture.

    • A paint spray booth with a filter and means within the spray booth to incinerate paint from the filter. A filter particularly adapted for collecting paint overspray in a paint spray booth. The filter has a plurality of members with a first portion parallel to the path of the air and paint particle flow which is to be filtered, each of the members having a second portion extending normally in a first direction from the downstream side of the first portion. The second portions of the members are spaced from each other and form openings therebetween on a plane normal to the flow of air and paint particles. Each of the members has a third portion extending from the other side of first portion and in the opposite direction from the second portion, and the third portions of the members form slots between members with areas less than the area of the downstream openings. Each of the members also having a fourth member extending perpendicularly from the end of the second member opposite the first member toward the third member, and a fifth member extending perpendicularly from the end of the third member opposite the first member and away from the first member.
