    • A differentiator device used in a system circulating a liquid coolant, in which a biased pressure applying member moves to reflect changing temperature induced density of the coolant. A temperature scale is attached to the piston and is in such relative projecting relation to the device that temperature graduations thereon may be read by reference to a portion of the device. The amount of expansion volume may be visually indicated and may be simultaneously compared with an amount proper for the existing ambient temperature. Further, the scale is constructed for manipulation by which the pressure applying member may be preset in charging or filling the system, whereby to insure a properly charged system operative over the complete temperature range.
    • 用于循环液体冷却剂的系统中的微分装置,其中偏置的压力施加构件移动以反映冷却剂的变化温度感应密度。 温度标尺连接到活塞上并且与设备成这样的相对突出的关系,其中可以通过参考设备的一部分读取温度刻度。 膨胀体积的量可以在视觉上指示,并且可以与适用于现有环境温度的量同时进行比较。 此外,为了进行操作而构造刻度尺,通过该刻度可以在加压或填充系统时预先设置压力施加构件,从而确保在整个温度范围内操作的适当充气的系统。

    • A heat reclaimer for the exhaust flue of a heating unit comprising, a housing having an air input space, an air output space, and an exhaust space, with a plurality of tubes connected between and communicating the air input space with the air output space and extending through the exhaust space. The exhaust flue of the heating unit is connected into the exhaust space of the housing and an exhaust output is connected to the housing extending from the exhaust space for venting exhaust coming from the heater into the exhaust space to a chimney, for example. A float or level switch is connected to the housing near the bottom of the exhaust space for switching, for example, an alarm if water accumulates in the exhaust space from condensed water vapor in the exhaust. At least one hole is also provided in the housing above the level of the float switch to permit condensed water to leave the exhaust space. The hole is provided in case the float switch clogs with soot. A wiping device may also be provided in the exhaust space for wiping the exterior surfaces of the tubes and removing films of water and soot which might accumulate thereon and reduce their heat transfer capacity.
    • 1.一种用于加热单元的排气烟道的热回收器,包括:具有空气输入空间的壳体,空气输出空间和排气空间,多个管连接在空气输出空间与空气输出空间之间并将空气输入空间与空气输出空间连通, 延伸通过排气空间。 加热单元的排气烟道连接到壳体的排气空间中,并且排气输出端连接到从排气空间延伸的壳体,用于将来自加热器的排气排放到排气空间中,例如被排放到烟囱中。 浮子或液位开关连接到排气空间底部附近的壳体,用于切换,例如,如果水从排气中的冷凝水蒸汽积聚在排气空间中,则进行报警。 至少一个孔还设置在壳体上方的浮子开关的水平面上,以允许冷凝水离开排气空间。 如果浮子开关堵塞煤气,则提供该孔。 也可以在排气空间中设置擦拭装置,用于擦拭管的外表面并去除可能积聚在其上并降低其传热能力的水和烟灰的膜。
