Abstract: The present disclosure describes a telecommunications structure including a plurality of mounting members each having a length and a diameter, the plurality of mounting members includes one or more vertically-oriented mounting members that intersect with one or more horizontally-oriented mounting members to form a frame that is configured to have telecommunications equipment mounted thereto. Each of the one or more vertically-oriented mounting members or each of the one or more horizontally-oriented mounting members includes a plurality of longitudinally spaced-apart recesses configured to receive an intersecting horizontally-oriented mounting member or vertically-oriented mounting member and form a mechanical connection therebetween. A press tool for forming the recesses and methods of using the same are also described herein.

Abstract: A pressure equalization apparatus for decreasing or eliminating the pressure differential between the internal pressure within a sealed system and the external ambient air pressure while concurrently sustaining a dry atmosphere inside the enclosure. The apparatus includes a variable volume chamber coupled in fluid communication with the sealed system and adapted to change its volume as in relation to the pressurization of the sealed system. Gas flowing between the sealed system and the variable volume chamber, as the pressurization changes, is exposed to an adsorbent operative for dehumidifying the exchanged gas.

Abstract: A compressor control module for use with a pressurization system having a strain gauge transducer and a compressor. The compressor control module includes variable voltage references associated with low and high pressure limits, comparator circuits configured to compare the voltage from the strain gauge pressure transducer to the variable voltage references, a control logic circuit configured to logically combine signals from the comparator circuits, and a relay circuit configured to apply power to the compressor.

Abstract: Apparatus and method for drying articles either free of applied heat or with a significantly reduced heating requirement. The apparatus includes a drying gas source is operative to dehumidify a moisture-laden gas, such as ambient air, flowing in the flow path to provide a drying gas to a drying chamber of a receptacle holding the articles. The drying gas removes moisture, or other cleansing liquid, from articles held in the chamber. The drying gas and moisture entrained in the drying gas are exhausted from the receptacle. The apparatus may optionally be equipped to provide a cleansing liquid, such as water, to the receptacle for mixing with the articles before the drying gas is supplied.

Abstract: A system configured to deliver dry pressurized air, derived from ambient air, to underground or outdoor cables, conduit, waveguides, plenums or other air spaces for the purpose of preventing the ingress of moisture or contamination. The system includes a housing and a modular membrane pressurization unit removably received within an interior space of the housing. The housing has a base configured for being at least partially buried below ground level and an air intake above ground level. The modular membrane pressurization unit intakes humid ambient air from the environment surrounding the housing and generates a continuous supply of dry pressurized air housing that is routed to the underground air space.
