Abstract: FIELD: mass exchange column of packed type for gas (vapor)/fluid interaction; may be used in gas absorbing, rectification, washing; chemical, oil chemical, gas and other industries. SUBSTANCE: vacuum packed sectionalized column includes vertical cylindrical vessel. Outward-flow and inward-flow sectionalized grids are installed alternatively inside the vessel over its height. Outward-flow grids are made in the form of cones with vortexes directed upwards, and diameter equal to internal diameter of column vessel. Inward-flow grids are made in the form of cones with bases directed upward. The bases come in close contact with internal walls of the column. Generatrices are inclined at an angle twice as large as that for outward-flow grid. The grids are perforated in the form of arched slots with convex upward. The slots are placed uniformly in concentric circuits. Axes of arched slots on inward-flow grids are inclined at acute angle to generatrices from periphery to the center towards the same direction. Packing bed is placed onto each grid in disorder manner. Axes of arched slots of outward grids are inclined at acute angle to generatrices to periphery towards the same direction. Packing bed height at each grid is 2.5 of linear dimension of a packing member. EFFECT: improved mass exchange between gas (vapor) and fluid at the expense of increased interphase surface of mass exchange in free volume of the packing, and provision of fluid flow structure close to the model of ideal displacement in horizontal plane in radial direction with complete agitation over packing bed height in a section.

Title: High frequency attenuator using liquid metal micro switches
Inventor: DOVE LEWIS R
IPC: H01H61/02
Filed: 2002-11-25
Abstract: Resonance within an attenuator relay caused by stray coupling capacitances to, and stray reactance within the switched conductor that replaces the attenuator section, is mitigated by reducing the stray coupling capacitances to as low a value as possible, and by using a conductor that is a section of controlled impedance transmission line that matches the system into which the attenuator relay has been placed. A substrate having SPDT LIMMS switches on either side of a switched transmission line segment and its associated attenuator, all of which are fabricated on the substrate, will have significantly lower stray coupling capacitance across the open parts of the switches when the attenuator segment is in use. This will increase the frequency for the onset of the resonance driven by the RF voltage drop across the attenuator. A reduction in the amplitude of the resonance can be obtained by including on the substrate an additional pair of LIMMS damping switches at each end of the transmission line segment. These damping switches each connect a terminating resistor to the ends of the transmission line segment when the attenuator section is in use. This loads the resonator and reduces the amplitude of the resonance. Still further improvement can be obtained by locating one of the damping switches and its termination resistor near (but preferably not exactly at) the middle of the transmission line segment.
