The pneumatic cylinder shown is well equipped. The ideas to minimize noise and friction are useful. Good manufacturers use testing methods to monitor performance of pneumatic cylinders.
It just goes to show that paying close attention to the details in design makes a difference. Good to see some clever engineering to solve several issues simultaneously.
I always thought that the glass body lined air cylinder with the soft carbon piston was a great patent. Stiction in the Airpel cylinders I used was extrordinarily better than traditional actuator seals.
There is a ~75-year-old patent on this subject...my Dad's (Wallace M. Jones, Westinghouse Corp), regarding stick-slip reduction of piston O-rings. This allows the O-ring to rotate 1/4 turn in its groove. This was used in radar-controlled anti-aircraft guns.
I would be surprised if this problem was not solved by others decades ago. The USPTO should be an important tool for every design engineer.
Excellent article. It's always great to see engineering refinements that end up tackling difficult issues such as reducing friction, lowering energy consumption and reducing in traditional products like pneumatic cylinders. These improvements have a very positive effect on new product designs.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
