A capillary sampling array comprises a closely packed array of capillaries having any interstitial spaces therebetween filled with a material physically and mechanically compatible with the material from which the capillaries are formed and an outer jacketing material covering the closely packed array of capillaries.

An electronic smoking device, comprising a capillary buffer having a first end, a second end, a capillary buffer portion between the first end and a second end, and an vapor channel and a liquid conduit formed between first end and the second end and through the capillary buffer portion; the capillary buffer portion is operable to receive under capillary effect excessive liquid from the liquid supply.

A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

An arc tube assembly (10) for a protected high intensity discharge lamp. The assembly has a ceramic arc tube (12) with a short shroud (20) surrounding at least the arc chamber (14) of the arc tube. The short shroud (20) allows the frit seal areas (46) of the arc tube capillaries (18) to project beyond the shroud (20) and thereby operate at a lower temperature, thus increasing lamp life.

The invention discloses a boiler exhaust smoke waste heat deep recovery device and relates to the technical field of waste heat recovery. The key of the technical scheme is that the boiler exhaust smoke waste heat deep recovery device comprises a chimney, the chimney comprises a smoke inlet communicating with a boiler flue, multiple heat pipes and capillary pipes are arranged in the chimney in a penetrating manner and are made of metal, the two ends of each heat pipe and the two ends of each capillary pipe are connected with the side walls of the chimney correspondingly, and the heat pipes arelocated between the capillary pipes and the smoke inlet; a water inlet pipe and a water outlet pipe are arranged outside the chimney, all the heat pipes communicate with the water inlet pipe, and thecapillary pipes communicate with the water outlet pipe; a communicating pipe is further arranged outside the chimney, the communicating pipe enables the ends, far away from the water inlet pipe, of the heat pipes and the ends, far away from the water outlet pipe, of the capillary pipes to communicate. The boiler exhaust smoke waste heat deep recovery device has the advantages of quick heat recovery response and rapid water temperature rising; through arrangement of ash removing plates and a driving mechanism, ash removal can be conducted on all pipelines to ensure the thermal conductivity, heat collecting plates can be separated from the capillary pipes, and clean and thorough ash removal can be conducted on the capillary pipes and the heat collector plates.

The invention provides a method and device for conducting absolute measurement on electrical conductivity of solution and a high-temperature melt. The method includes the steps that (1) capillary tubes are fixed in the solution or the high-temperature melt to be measured, electrodes are connected with an LCR tester, and one or two electrodes are fixed on an electrode clamp and inserted in the capillary tubes; (2) resistance R1 is measured by the LCR tester; (3) the electrodes are controlled to move along the preset distance l, and then resistance R2 is measured; (4) the inner diameter of each of the capillary tube is measured; (5) the constant of a conductance cell is calculated; (6) the difference value of the resistance at two measuring positions is calculated; (7) the electrical conductivity is calculated. The device is divided into a single capillary tube conductance cell device and a double capillary tube conductance cell device and comprises the two electrodes, the capillary tubes, a capillary tube clamping device, the LCR tester, the electrode clamp and a servo system. According to the method and device for conducting absolute measurement on electrical conductivity of the solution and the high-temperature melt, the polarization effect and the fringe effect can be effectively eliminated, and the high-precision measuring result of the electrical conductivity of the solution or the high-temperature melt is acquired.
