High-frequency Discharge in Organic Vapours

Abstract: WHILE studying the rectification effect in some organic vapours, when ionised by electrodeless discharge, striations unlike the general type obtained by McCallum and Perry (NATURE, Jan. 12, p. 48) were observed to fill the whole tube. The diameter of the tube was different at different parts, varying from 0.5 cm. to 2.5 cm., but there was observed no essential difference in the pattern any-where excepting their increased luminosity in the narrower portion.

Device for steady voltage of preforming machine steam

Abstract: The utility model discloses a device for steady voltage of preforming machine steam, which comprises a tank body, the upper portion both sides of the jar body are equipped with intake pipe and outlet duct respectively, the bottom of the jar body is equipped with the outlet pipe, be equipped with the relief pressure valve in the intake pipe, be equipped with the trap on the outlet pipe. According to the structure, the utility model discloses a device for steady voltage of preforming machine steam, the vapours is after the relief pressure valve of intake pipe, and it is internal to get into the jar, and 1-1.5 standard air pressure within range was dropped to the atmospheric pressure of vapours this moment, through the effect of " L " venturi tube and screen panel, to cool down the vapours, the temperature that makes the vapours is at 110-115 degrees centigrade within range to satisfy the production needs in equipment later stage, water droplet after the vapours liquefaction can splash on dropping on jar ponding of body bottom, and through the effect of baffle, the water droplet after preventing to splash contacts with the vapours once more, through the effect of trap, make jar internal ponding exhaust guarantee simultaneously that the pressure of jar internal vapours can not reduce.

Heat and mass exchange apparatus between liquids and gases or vapours

Abstract: of EP01024801. Apparatus for heat and/or mass exchange between flowing liquids and gases or vapours flowing oppositely or transversely thereto, so that the liquids and the gases or vapours at least partly contact each other and wherein the liquid is carried by at least one liquid-guiding surface (1) having apertures (2) through which the liquid flows, characterized in that a turbulence element (3) projecting from the surface (1) is arranged in front of each aperture (2), taken in the direction of flow.

A solvent trap for oil vacuum pumps

Abstract: A trap is described which enables the vapours of organic solvents to be passed through an oil vacuum pump without contamination of the main oil reservoir. By this means a good vacuum can be obtained shortly after the evaporation of solvents.
