    • A system for use with a manhole vault having an internal atmosphere, and, optionally, with a ventilation stack connecting the vault to an external atmosphere. The system includes a manhole cover, a ventilation pipe, and an air moving assembly. The cover has one or more through-holes extending between top and bottom surfaces. Each of the through-hole(s) is in fluid communication with the external atmosphere at the top surface. The pipe has a through-channel that extends between first and second openings. The first opening is positioned proximal to either an opening into the ventilation stack or at least one of the through-hole(s) at the bottom surface of the cover. The second opening is positioned in the interior of the vault. The device is configured to cause a portion of one of the interior and external atmospheres to flow through the through-channel toward a different one of the interior and external atmospheres.
    • 一种用于具有内部气氛的人孔拱顶的系统,以及可选地具有将该拱顶连接到外部空气的通风堆。 该系统包括人孔盖,通风管和空气移动组件。 盖具有在顶表面和底表面之间延伸的一个或多个通孔。 每个通孔在顶表面与外部大气流体连通。 管道具有在第一和第二开口之间延伸的通道。 第一开口位于靠近通风叠层的开口或盖的底表面上的至少一个通孔中。 第二个开口位于拱顶的内部。 该装置被配置成使内部和外部气氛中的一个的一部分流过穿过通道的内部和外部气氛中的不同的一个。

    • A flexible inspection and access view port window that conforms to the shape of air ducts present in forced air heating, cooling and ventilation systems and held in place using a border layer which is magnetic or peelable adhesive, so that it can easily be installed, removed and re-installed without tools. This device allows the user to visually inspect the air ducts by sighting the clarity of a graphic viewing target with border attached within the duct. The graphic will be obscured with an accumulation of dust or other contaminants. Air pressure integrity inside the air duct system is maintained without the use of sealing gaskets or screws. The viewer can assist inspection with the aid of an optional light by activating a switch at the time of inspection. An optional dust alarm can also be installed that will trigger an audible or visual alarm when the accumulated dust level inside the duct exceeds a preset threshold.
    • 灵活的检查和检视视窗窗口,符合强制空气加热,冷却和通风系统中存在的空气管道的形状,并使用磁性或可剥离粘合剂的边界层保持就位,从而可以方便地安装,拆卸 并重新安装没有工具。 该装置允许用户通过观察图形观察目标的清晰度来直观地检查空气管道,边界附着在管道内。 该图形将被灰尘或其他污染物的堆积遮蔽。 在不使用密封垫圈或螺丝的情况下,保持空气管道系统内的气压完整性。 观察者可以通过在检查时激活开关来辅助可选灯光的检查。 还可以安装可选的防尘报警器,当管道内累积的灰尘水平超过预设阈值时,可以触发声音或视觉报警。

    • A readily demountable door assembly for sealing an aperture in a duct comprises a door member having an inwardly directed ramp or cam which lies within the duct and is inclined outwardly toward the duct surface. A clamp is adapted to be mounted adjacent the aperture of the duct at a position diametrically opposite the ramp. The clamp engages the door and shifts the same in the direction of the ramp, which movement presses the flange of the door tightly against the duct surface, the clamp including portions which overlie the door at positions remote from the ramp to urge such remotely disposed portions of the door against the duct surface.
    • 用于密封管道中的孔的容易拆卸的门组件包括具有位于管道内并向管道表面向外倾斜的向内指向的斜面或凸轮的门构件。 夹具适于在与斜坡直径相对的位置处邻近管道的孔安装。 夹具接合门并沿着斜坡的方向移动,该运动将门的凸缘紧紧地压靠在管道表面上,夹具包括在远离斜坡的位置上覆盖门的部分,以推动这种远距离设置的部分 的门对着管道表面。
