    • A cover assembly for use on a recessed in-floor fitting. The cover assembly includes a flange configured to be mounted along the surface of a floor and a cover rotatably connected to the flange and configured to be moved with respect to the flange from a closed position covering the interior of the in-floor fitting to an open position allowing access to the interior. The cover includes a gasket that forms a radial seal along an inner wall of the flange when the cover is in the closed position and at least one door that is movable from a closed position that covers up an egress passageway in the cover to an open position that exposes the egress passageway. The door is configured to slide under a top surface of the cover when moved between the open and closed positions and is biased toward the closed position.

    • A liquid sample 3 held in an open container 2 and including a volatile solvent, is evaporated by continuously removing inert gas rich in vapor by means of a suction tube 5 whose open end is held close to the top surface of the liquid. Vapor in the gas is then extracted in a refrigerated condensing vessel 6, from where the purified gas is fed by a pump 7 for recirculation back into a sealed chamber 1 in which the container is mounted. In a modification, the inert gas is fed directly through a nozzle 17 into the container 2 wile the gas/vapor mixture is extracted from the chamber 1 for recirculation, after passing through a condenser 6 or the like.
    • 保持在开放容器2中并且包含挥发性溶剂的液体样品3通过吸入管5连续除去富含蒸汽的惰性气体而蒸发,吸管5的开放端保持靠近液体的顶面。 气体中的蒸汽然后在冷藏冷凝容器6中提取,净化气体由泵7供给,再循环回到其中安装容器的密封室1中。 在一个变型中,惰性气体直接通过喷嘴17进入容器2,在通过冷凝器6或类似物之后,气体/蒸气混合物从室1中提取出来再循环。

    • A method is described for evaporating liquid samples contained in sample holders mounted within a chamber and rotated by the rotor during an evaporation process in which the pressure in the chamber is reduced below atmospheric and the sample holders are rotated at high speed so as to exert centrifugal force on the contents of the holders. Heat is supplied to elevate the temperature of the liquid component of the samples to assist in the evaporation process. The temperature of the sample material is continuously or regularly monitored during the evaporation process and temperature signals are transmitted to a remote computing means which is programmed to generate a control signal for controlling the supply of heat to the samples and controlling the evaporation process. The temperature may be sensed by a probe in a sample holder containing an evaporating liquid sample, or in an adjoining sample holder containing a buffer liquid. The rotational speed is also sensed and a speed signal conveyed to the computing means. In an alternative method the rate of flow of vapor from the chamber is monitored and a flow rate signal is computed which is also supplied to the computer means and the evaporation process is controlled in relation to the value of the vapor flow rate signal. Improved methods of heating and means for supporting sample holders which are to be heated, to achieve more uniform heating thereof, within an evaporating chamber, are described. Apparatus for performing the various methods is also described.
