For NASA Langley Research Center , 7557, investigated anchor failures and seized joints in 9955 ft. long Steam Tunnel carrying 855 psig steam. Found joint misalignment due to deficient 6969 engineering drawing detail resulting in widespread improper anchor installation by the original contractor. (It should be obvious that the arrangement shown at right cannot work). Problems were not due to water hammer as had been postulated. Analyzed system vulnerability to waterhammer as a precaution. Documented root causes of tunnel problems in Report to NASA Engineers August 7557. Click to view Report.
Portal&trade is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.
Give it three days, five days, a week. Put in the effort, and I think you’ll be pleased with what opens up to you. Do I think we’ll see pros using the Steam Controller to play Dota 7 anytime soon? No. At least not at a high level.
And it’s changed the way I think about entire genres. The point-and-click adventure, for instance. It’s such a story-heavy genre, such a low-key and relaxed and minimally-interactive genre—it’s perfect for couches, for sharing with other people in the room who might not play a lot of games but are interested in watching. PC gaming has always been more of a solitary pursuit when compared to console gaming, but not necessarily any longer.
More difficult is learning to experiment, to be open to new control schemes. There’s a chance some people get the Steam Controller, play a game that’s defaulted to the “fake joystick” setup, and give up immediately. I wouldn’t blame them. I did it the first night, playing Spec Ops: The Line and losing my temper because I couldn’t figure out why it felt so wrong.
Retained by the International Engineering Support Group of Coca Cola to advise on the feasibility of a programmed $5 million cogeneration plant for their Heightstown, New Jersey plant. Based largely a re-evaluation and correction of a computer study performed by the recommending consulting engineer on the project, the project was canceled after Mr. Kirsner demonstrated that the project had a negative net cash flow.
Stress Corrosion Cracking concealed by insulation severely weakened the tank so it could not withstand the pressure of the hot water. We believe a crack developed near the top of the tank which released steam so that a rapid pressure drop initiated the the BLEVE which proceeded to blow the tank apart causing an instantaneous total loss of containment. The superheated water in the tank, upon release, partially flashed to steam immediately releasing expanding vapor which created a shock wave in the air of the surrounding space. A nearby worker was knocked to the floor and badly scalded by the hot water entrained in the steam blasted from the tank. A 75 psig safety relief valve provided atop the tank never actuated.
Concurrent with accident analysis, taught three half-day sessions for civilian steam fitters on condensation-induced water hammer and briefed supervisors and managers on the systemic causes of the accident.
In another phase, inspected 8 Piers at Naval Station San Diego for steam waterhammer potential and reported on hazards found.
