LGMI Weekly 22 Oct 14: A pause for an inspiration

 Why can't we "print" concrete foundations, walls and other such structures we need?  Why can't industry build us a "3-D" printer that moves through a construction site and prints concrete?  The "gunite" process has essentially been the early generation of this for years.3-D printed concrete eliminates forms.  This is a huge savings.  We could also print small structures, such a pump…See More

3 Sept 14: Applications in Use, II--PVC and CPVC Piping

We found a report, admittedly a bit dated, on the use of PVC (and CPVC) not only as piping components, but also in other applications.  One of the striking bits of information is found on page 9 of this report: "PVC has captured an 80% share of the buried pressure water pipe market in diameters greater than 100 millimeters."  It is worth reading the entire report, especially if you are still using steel or stainless steel pipe in applications where CPVC or PVC has proven itself.

Applications in Use, I--Steel Dryer Cans

We are going to start a new subject this week.  Over the past five years, we have proposed more than 160 ideas to reduce weight and/or improve performance of paper machines and pulp mills. Now, we are going to start identifying suppliers and known applications where these have been implemented, with or without our inspiration. This week, we highlight steel dryer cans. Check out the latest LGMI Weekly…See More

What is "this"?  Putting a charge on the stock in the headbox and using this charge to drive drainage. The latest LGMI Weekly.See More

If one goes back to the late 1950s, early 1960s, automobiles and paper machines were made of nearly the same thing: lots of steel

However, starting in the late 1960s, early 1970s, these paths diverged.  Automobiles went to plastics and other materials, such as aluminum.  Paper machines stayed with steel, but moved to a larger percentage of stainless steel. Check out the latest LGMI Weekly.See More
