Some things never change. Combine one part sodium with one part chloride, and you'll always get salt. Always did, always will.
The laws of physics and chemistry don't change. And because fluid power is a branch of physics, the fundamentals of hydraulics and pneumatics don't change. That's why we have archived so many articles from years past. The lessons that were learned in articles from years ago are just as relevant today as they were when the articles were originally published.
I frequently look at back issue
s of Hydraulics & Pneumatics. When I do, I often find articles that were published before we had a website, and, frankly, they're just too good to remain hidden inside an archived volume. So when I find articles that are especially interesting and that still provide relavent lessons in fluid power technology, I rescue the aritcle from the archives to give it new life on our website.
Two such articles have just been posted. One reveals behind-the-scenes technology from the 1976 remake of the classic, King Kong. The article explains how hydraulics offered the only solution to design and bulid a system in only weeks. It also reveals how an unforeseen safety problem was quickly solved — a problem that could've easily injured Oscar winning actress Jessica Lange. Click here to view the article.
The other article describes the hydraulic system of an article heart. Actually, it's a left-ventical assist device, but it describes the challenges of designing and buliding a huydraulic system that works inside the human body. Naturally, extremely high reliability, cleanliness, compact size, and low heat generation were essential. Click here to view this article.
As always, thanks for your interest, and I hope you get as much out of these classics as I do.
