Spiral grooved vacuum pump working in high pressure ranges.

Vacuum Gauge to Vacuum Pump Valve

A New Unique High-pressure Pump System

The combination of a 16 inch Pitot tube pump with a switched reluctance motor represents a significant development in the field of high-pressure pumping. A field proven Pitot tube pump design has been mechanically integrated with a high performance switched reluctance motor. The resulting system is approximately 40 percent of the size of the standard unit it replaces. The closecoupled pump elim...

Room-temperature spin-spiral multiferroicity in high-pressure cupric oxide

Multiferroic materials, in which ferroelectric and magnetic ordering coexist, are of fundamental interest for the development of multi-state memory devices that allow for electrical writing and non-destructive magnetic readout operation. The great challenge is to create multiferroic materials that operate at room temperature and have a large ferroelectric polarization P. Cupric oxide, CuO, is p...

Monitoring sterilization of dressings in high-vacuum pressure-steam sterilizers.

Undetected air leaks in a high-vacuum sterilizer can defeat the sterilization process. For this reason the maintenance and supervision of these sterilizers needs expert engineering care. The importance of controlling the high-vacuum sterilization process from the centre of a load rather than the chamber drain is emphasized, and a method of detecting any failure in a high-vacuum process is descr...
