Dow Corning demonstrated a very interesting glass bonding technique at the annual international conference called GlassCon Global. Co-authors gave a detailed overview of advanced bonding techniques used in the Airborne America San Diego skydiving tunnel – an extreme-sport facility for those who want to skydive without jumping from an airplane. The presentation described the engineering analysis, design of the adhesive attachment system, and the testing of the adhesive for validation,

Portable line boring machines are saving construction companies lots of money. Heavy equipment track rollers, attachment pivot point holes, and all of those turning and pivot points on construction equipment wear notoriously. Adequate lubrication goes a long way in extending the serviceable life of these attachment points but eventually repairs are needed as the holes become enlarged and out-of-round. The repair process that is widely used is to build up the inside of the hole with weld and then precisely bore the hole to the correct dimension for the pin. In some cases the hole is rebored to accommodate a bushing.

If you want to take a trip into some mind twisting territory just try investigating natural lighting. By the time you finish connecting the relevance of degrees Kelvin to ‘color rendering index’ you’ll be more in the dark than when you started. But, natural lighting is important because light regulates our sleep-wake cycle. And, lack of sleep can lead to health problems, low productivity and even bad behavior.

There are at least a couple of approaches to constructing smart roads. One way is to erect traffic signal controllers that will “broadcast signal, phase and timing (SPaT) information to vehicles.” WSP USA (formerly WSP – Parsons Brinkerhoff) is consulting with Minnesota to do this between downtown Minneapolis and parts of Interstate 394. At first, the system will manage traffic signals to benefit the snow plows. It will also provide road construction information to motorists through dynamic message signs, mobile apps and radio. And, bus drivers will get early warnings about pedestrians in crosswalks.
