FLUID POWER: Two new KNF swing-piston pumps introduce ideal solutions to transfer, evacuate, or compress air or inert gas and deliver oil-free performance without any potential risk of contamination. The new models include a compact and efficient 3.3 l/m micro pump and a 25 l/m mid-size version with both providing vacuum or pressure capabilities.Their addition broadens the KNF swing-piston product line to include pumps offering flow ranges of 3.3 l/m, 9 l/m, 18 l/m, 25 l/m, 50 l/m and 78 l/m with vacuums to 27.6 inch Hg and pressures up to 100 psig., depending on type.
Among features, the sealing lip between the cylinder and wall has been designed to minimize frictional loss and promote a long service life, while running quietly with minimal vibration. Pumps can operate in any position and are supplied ready for installation.
All versions can be specified with ac motors, brush-commutated dc motors or brushless dc motors (with brushless types engineered for longer service life and allowing for pinpoint speed control).
These pumps can be used for a wide range of OEM applications requiring reliable pneumatics. Standard versions can be customized to meet particular OEM requirements.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
