ecodvpBecause of the simplicity of its design, the EcoDry L can offer extended periods of completely “dry” operation.

Producing low-cost, oil-free, maintenance-free mechanical pumps for roughing/backing applications has been the goal of vacuum pump manufacturers for the past 20 years. One impediment to attaining this objective has revolved around eliminating oil, which plays many roles in the operation of mechanical pumps. Not only does oil reduce friction between the sliding and rolling elements inside the pump, it also seals vacuum compartments and conducts heat away from the pump’s interior regions.

One way to eliminate oil …

smeciwThirty years after she thought she had bid her counselors good-bye forever, Patricia Marx returns for a summer camp reunion and discovers that Pinecliffe hasn’t changed. She has.

From the age of 9 to 14, I spent two months every summer at Camp Pinecliffe, a girls’ camp in Maine that stressed competitive sports and, if I remember correctly, desserts. Last summer I returned to Pinecliffe for the Alumnae 80th Anniversary Celebration Weekend. I wondered how the camp had changed, but mostly, I wondered if I–who today would rather not share a room with myself, let …

itcsmIt’s the voice in your head telling you yes, you should save that scrap of tinfoil, and no, it’s not okay to buy the really soft toilet paper. Your spending quirks and what they say about you.

It’s ten o’clock on Saturday morning, and I’m standing at the bathroom sink, saving money. In my left hand, I’m holding a nearly full bottle of hand lotion, in my right, a nearly empty one, with a pump that no longer reaches the lotion at the bottom. I’m attempting to pour the contents of the old into the …

For savers and conservative investors nothing is more popular than Series EE Savings Basbwitonds. They’re issued by the government and designed for those who don’t want to risk losing any money. Some $5.3 billion worth were sold in the last fiscal year. Buyers think of them as simple and safe.

Safe, yes. But they’re not always as simple as you may think–especially in view of the many changes that have been made in recent years. Here are answers to the savings-bond questions I get asked most often:

1. WHAT DO I PAY?

You pay …

fearecrRita Bernstein of Wilton, CT, was pleased when daughters Chelsea, 7, and Haylee, 3, developed a taste for mesclun salad. Samantha, 10, wasn’t a fan of fancy greens, nor was their father, Larry. But none of them dreamed that such a healthful food would nearly destroy their family.

One night in June 1996, after several meals that had included the salad, Rita and the two girls developed severe cramps and diarrhea. Over the next 48 hours, Rita improved, but her daughters grew sicker. “The diarrhea was uncontrollable; both girls were becoming dehydrated,” Rita recalls. “Haylee …

aumgtlcoMost parents notice, when their infant first begins to learn how to use his hands, that the child first learns to reach for whatever it is he wants with one hand. Grasping with one hand accomplished, he embarks on a period of trying to grasp everything with two hands, using the naive theory: “One hand good. Two hands better.” Eventually, the child learns that, while some things are done better with both hands, there are many times when the second hand doesn’t help, and may even get in the way.

The same phenomenon appears in …

phogyamiAlthough photographic evidence was crucial to his reports, Clarke had no satisfactory way to reproduce and transmit his images without incurring unacceptable losses in resolution and contrast quality while relying on Polaroid prints. Now he can transmit them worldwide as digitally captured by storing them as files on a local area network server.

Clarke uses three digital imaging systems, including a scanning electron microscope, in his lab at Case. The most used system, however, is the Kodak MegaPlus camera, model 1.6i/AB, which he relies on for grayscale imaging. The camera employs a 9 x 13-mm …

takntubThe wake of its progress will carry investment casting forward for many years to come. In fact, Howmet, PCC, GEAE, and Pratt & Whitney are already riding that wake in another agreement, along with the U.S. Air Force, Allison Engine Co. in Indianapolis, and Lockheed-Martin Aeronautical Systems in Marietta, Ga.

Started in 1995, it is called the Engine Supplier Base Initiative (ESBI), and it is planned to run six years. Part of ESBI’s objective is to efficiently utilize newly developed technology, such as that produced by ICCA, in a continuing campaign to strengthen the U.S. …

mavThe systems comprising an MAV include the airfoil or lift system, a propulsion or energy source that meets airborne and ground movement needs along with the power requirements for support systems, control surfaces to meet a flight profile, sensors specific to mission requirements, a microprocessor that allows the MAV to fly autonomously and collect information, and a communications system that allows the MAV to transmit or store (for subsequent downloading) collected data.

MAV airfoils are relatively small and subsequently sensitive to anything other than perfect wind conditions. Wind gusts, rain, snow, and even steady high …
