20100165311 | Linear Motor Magnetic Shield Apparatus - A magnetic shield having non-magnetic gaps provides reduced magnetic cross-talk for a linear motor array in a precision positioning system. Redirecting the leakage flux limits the cross-talk and associated deleterious effects. Such preferred magnetic circuit paths for the leakage are affixed to the moving magnet system of the linear motor. Embodiments of the preferred flux leakage paths are realized by providing a ferromagnetic shield separated by a non-magnetic gap between the permanent magnets and the back-irons. In another embodiment, the ferromagnetic shield separation includes diamagnetic materials. | 07-01-2010 |

20080295523 | Machined Spring With Integral Retainer For Closed Cycle Cryogenic Coolers - A retainer and spring with threaded end are machined from a single piece of material for threading to a piston in a closed cycle cryogenic cooler. Since the machined retainer and spring are a unitary part, they cannot rub against each other during operation of the piston which reduces debris generation. The spring is preferably formed as a double start helix which further increases axial stability and reduces side loading. The spring extends into an integrally formed, threaded end at the end thereof opposite the retainer. The spring is therefore solidly connected to its adjoining parts which greatly reduces tilting and off-axis movements inherent in the prior art, wound spring designs. | 12-04-2008 |
