A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

Consider a world composed of nanometre-sized factories and self-repairing molecular machines where complex and responsive processes operate under exquisite control; where translational and rotational ...

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now produced a light driven rotary motor in which ...

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...

Light-driven molecular motors were first developed nearly 25 years ago at the University of Groningen, the Netherlands. This resulted in a shared Nobel Prize for Chemistry for Professor Ben Feringa in ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

On Jan. 28, 1919, 25 men gathered in the St. Charles Hotel in downtown Cape Girardeau to be initiated into a brand-new Rotary Club -- the first such club in Southeast Missouri. The Rotary movement had ...

What makes rotary ball splines ideal for dual motion How preload influences spline performance Why groove shape and ball contact matter The pros and cons of crossed-roller vs. angular-contact bearings ...

STACEY: HUNDREDS OF CHILDREN AND ADULTS ACROSS THE METRO ARE GETTING BRAND NEW COATS THIS WINTER. IT’S ALL THANKS TO THE ROTARY CLUB OF DES MOINES A.M. AND OPERATION WARM TODAY MORE THAN 150 COATS ...

Rotary in Cedar Rapids officially marks its 100th year in April. It began with 18 men meeting at the Montrose Hotel for lunch March 23, 1914, to lay out preliminary plans for the Cedar Rapids Rotary ...
