Preventing gas from occupying a spray nozzle used in a process of scoring a hot glass sheet

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.

Dynamic desiccation cooling system for ships

The present invention describes methods and apparatus for controlling the humidity of air supplied to cooling coils on a gas turbine powered ship through a dynamic desiccation system. The system passes supply air through a desiccant wheel, which dries and concomitantly heats the supply air. This supply air stream is then passed through a rotatable thermal wheel, wherein heat is transferred from the dry supply air to an exhaust-air mixture, thereby conditioning the supply air for delivery and circulation to a plurality of cooling-coil units in a plurality of compartments. The exhaust air from the compartments is first mixed with some of the treated supply air to lower the absolute humidity to a value needed for effective regeneration of the desiccant wheel. An evaporative cooler then conditions the exhaust-air mixture for effective cooling of the supply air in the thermal rotor, which also serves as an air preheater for desiccant regeneration. The exhaust-air mixture is then heated to the desiccant regeneration temperature by passing the preheated exhaust air through a heat exchanger supplied with gas-turbine waste heat. After this heated exhaust-air mixture regenerates the desiccant wheel by fully drying out the desiccant on the wheel, it is expelled from the fan room.

PH2OCP - portable water and climatic production system

ActiveUS20110056220A1The temperature drops quicklyEnormous operational versatilityGas treatmentAir treatment detailsCooling coilProduced water
The present invention “PH2OCP” relates to a portable water and climatic production system. In the preferred embodiment, the system uses a combination of heating coils assemblies, cooling coils and more specifically the desiccant rotor technology for the extraction, collection of water vapor molecules from the air stream and transformation in to condensate for the production of clean filtered potable water.The portable water and climatic production system or “PH2OCP” is designed to operate and produce water in a wide range of global climatic conditions, including the most arid of environments. This is made possible due to the highly effective performance capabilities of the desiccant rotor technology in the extraction of water vapor molecules from any existing ambient air.The desiccant technology is designed in the “PH2OCP” to operate in combination with the microwave reactivation system in the regeneration or reactivation section and cooling coils assembly located in the condensation section.
