    • A pre-tensioned closure for a side exhaust opening through wall of a building roof ventilator wherein a damper is pivotally received within a frame opening and torsion bar biased to closed position and wherein the frame thereof is vertically received within the ventilator wall opening in a manner whereby higher than atmospheric pressure within the ventilator urges the damper against the torsion bar for at least partial opening for permitting outward passage of air, but the damper is normally biased to a vertically closed and weather sheltered position within the frame.
    • 一种用于建筑物屋顶通风机的侧面排气开口通过壁的预张紧的封闭件,其中阻尼器枢转地容纳在框架开口和扭力杆中,所述框架开口和扭杆被偏压到关闭位置,并且其框架以垂直方式容纳在通风机壁开口内 由此在呼吸机内高于大气压迫使阻尼器抵靠扭杆至少部分打开以允许空气向外通过,但阻尼器通常被偏压到框架内的垂直关闭和气候遮蔽位置。

    • A grate assembly (10) for a gasifier for gasifying carbonaceous material producing ash includes an upper rotatable grate component (11) and a lower rotatable support structure (12) fastened to the upper rotatable grate component (11) by a plurality of removable fasteners (15) acting to prevent vertical displacement of the upper rotatable grate component (11) and the lower rotatable support structure (12). The lower rotatable support structure (12) is configured to be drivingly rotated about a common vertical axis of rotation (21) shared with the upper rotatable grate component (11). The assembly (1) further includes at least two key torque transmitters (16) spaced angularly relative to the common axis of rotation (21) and engaging the upper rotatable grate component (11) and the lower rotatable support structure (12) to transfer torque from the lower rotatable support structure (12) to the upper rotatable grate component (11) when the lower rotatable support structure (12) is driven.
    • 用于气化含碳材料产生灰分的气化器的炉排组件(10)包括上部可旋转炉排部件(11)和通过多个可移除紧固件(12)固定到上部可旋转炉篦部件(11)的下部可旋转支撑结构(12) 15),用于防止上部可旋转格栅部件(11)和下部可旋转支撑结构(12)的垂直位移。 下部可旋转支撑结构(12)构造成围绕与上部可旋转格栅部件(11)共享的公共垂直旋转轴线(21)驱动旋转。 组件(1)还包括至少两个相对于公共旋转轴线(21)成角度地间隔开的关键扭矩传递器(16),并且与上部可旋转格栅部件(11)和下部可旋转支撑结构(12)接合以传递扭矩 当下部可旋转支撑结构(12)被驱动时,从下部可旋转支撑结构(12)到上部可旋转格栅部件(11)。
