Not Your Typical Acoustical Ceiling

Acoustical barrier ceilings are used to reduce noise transmission between rooms. These multiple layer sheet rock barrier ceilings should not be confused with light weight drop in acoustical ceilings, whose primary function is to absorb sound within a room, but have virtually no effect on noise transmission. We have had the pleasure of working with…

Expansion Joints for Vibration Isolated Exhaust Piping

Designing an exhaust piping system in a seismic zone can get complicated. The extreme change in temperature of the exhaust piping very often requires the introduction of an expansion joint to keep the pipe stress at an acceptable level as the pipe grows, and the seismic restraints have the opposing task of keeping the pipe…

Emergency Generators Float on Air Springs

Air springs are the best solution for eliminating structurally transmitted noise and vibration from equipment to acoustically sensitive areas. Air springs support equipment with pressurized air within a thin walled rubber container, similar to, but lighter than the side walls of an automobile tire. Even high deflection steel springs cannot match the air spring’s natural…

Going GREEN by going Digital

Times have changed. When I started at Mason Industries over 31 years ago I was put behind a drafting table, equipped with a set of triangles, a tee square and few pencils. A couple of years later Norm Mason gave everyone a calculator (I am still using the same TI-56 SLR). New engineers can design…

Not in the catalog? No problem

Last August, we received an unusual request from an engineering firm working with Shell Oil on a new oil and gas platform. They wanted to know if we could build a semi-circular bumper system for risers used in deep sea drilling. Ocean currents were causing their piping to move within their riser clamp and imposing…

Northeast Arkansas Baptists Hospital

Northeast Arkansas Baptists Hospital is a 750,000 square foot facility in Jonesboro, Arkansas. It will be the largest surgical campus in the region when completed in June 2013. Jonesboro is only 100 miles from the New Madrid Fault, which back in 1812, produced the largest earthquake ever recorded in the continental United States. The piping…

Dynamometer Isolation

Large “Rolling Road” type dynamometers, like the one shown below are used throughout the auto industry to measure engine and complete automobile performance. The rear wheels are centered on the roller or rollers and the car locked in place. The engine output and other data can be collected and analyzed based on the resistance and…

Shaker Table Testing

One of our competitors has taken on the role of consultant and has retained a few HVAC manufacturers on a fee basis. This charge is for guidance through shaker table tests that simulate earthquakes in California as required under the new codes. Since they use their own products in the tests, which gain approval at…
