A spray nozzle is used in a process of quenching a hot glass sheet during a laser scoring process or other high energy glass heating process. The scoring is conducted by a high energy means such as a laser. The nozzle is located in proximity to the glass sheet, creating gas in liquid used to quench the glass located in the nozzle (e.g., water). The gas (e.g., air bubbles) is removed from the quenching liquid. Then, the spray nozzle is used to spray the quenching liquid onto the sheet at a location trailing laser scoring of the sheet, such as using a traveling anvil machine at the bottom of the draw. The spray nozzle (purge nozzle) has a purge opening and tubing leading to a discharge location. The purge nozzle can have a sloped passageway that pre-stages gas bubbles near the purge opening in the nozzle. The spray nozzle can include a cooling coil passing around the nozzle passageway that enables a coolant to travel along the coil. This cools the quenching liquid passing through the nozzle, and increases the solubility of bubbles in the quenching liquid in the nozzle. A gas filter can receive gas-rich quenching liquid from the pressurized quenching liquid source, remove gas from the liquid, and send gas-depleted quenching liquid to the spray nozzle.

A sealed Hard Disk Drive filled with an inert gas mixture of air, helium, and/or nitrogen provides a wireless data encrypted interface to facilitate data and control transfer with a host system. The wireless interface additionally allows power transfer through Radio Frequency (RF) propagation or electromagnetic induction. Extended measures for vibration, shock, and temperature control are made possible through the use of the wireless interface. Immersion of the HDD into a viscous gel, or other damping material, provides vibration and shock control, while heating/cooling coils provide temperature control.
