    • A fuel-fired, forced draft air heating furnace has a draft inducer fan disposed in a vestibule chamber having an exterior wall with an air intake opening therein. During operation of the draft inducer fan its motor is cooled by combustion air drawn inwardly through the air intake opening. To enhance the combustion air cooling of the draft inducer fan motor, a deflection plate is supported within the vestibule chamber in an inwardly spaced apart, facing relationship with the air intake opening. A portion of the combustion air flowing inwardly through the air intake opening impinges on and is redirected by the plate toward the motor via a substantially unenclosed flow path within the vestibule chamber.
    • 燃料燃烧的强制通风空气加热炉具有设置在具有外壁并具有进气口的前庭室内的通风机风扇。 在牵引风机的运行期间,其电动机由通过进气口向内吸入的燃烧空气冷却。 为了增强牵引引风扇电动机的燃烧空气冷却,偏转板以与进气口形成向内间隔的方式支撑在前庭室内。 通过进气口向内流动的一部分燃烧空气通过板前进中的基本未封闭的流动路径朝向前述电动机撞击并由该板转向电动机。

    • The present invention relates to a drum magazine, and more particularly, to a drum magazine in which a wheel cover, which is configured to provide an elastic force via a mainspring to a bullet guide unit configured to elastically support a bullet loaded in a drum at a loading hole which is an inlet of the drum, is rotatably disposed at an outer surface of the drum, wherein, at the time of loading, an elastic latch unit is elastically engaged with an inner ring gear of the wheel cover and allows rotation of the wheel cover only in one direction so that a loading space at an entry of the loading hole that is provided due to arbitrary rotation of the wheel cover in the one direction is maintained as it is even when a user removes his or her hand from the magazine, and, after the loading is completed, a latch control unit configured to disengage the elastic latch unit and the inner ring gear is operated so that an elastic restoration force of the mainspring, which is accumulated due to the loading, is transmitted to the bullet guide unit and the loaded bullet is elastically supported at the loading hole.
