Abstract: The present invention relates to the use of a preservative combination for inhibiting growth of gram negative bacteria in or on a meat product. The invention also relates to a method for reducing growth of gram-negative bacteria in or on a meat product. The invention also relates to a meat product, treated with said preservative combination.

Abstract: A method and system for thermally activating a oxidizing cleaning gas for use in a semiconductor process chamber cleaning process. The oxidizing cleaning gas is thermally activated by reacting the oxidizing cleaning gas with heated inert gas. The resulting thermally activated oxidizing cleaning gas does not readily deactivate, thus providing enhanced cleaning capabilities.

Abstract: The present invention is directed to a process and system for the versatile operation of process equipment, and especially semiconductor process chamber clean equipment, from any pressure level ranging from a vacuum to just less than one atmosphere absolute. The system of the present invention provides a storage vessel capable of storing gas at sub-atmospheric pressure and a vacuum pump. By using a vacuum pump, the vessel stores a reasonable quantity of gas without being pressurized above atmospheric pressure. Therefore, the entire capacity of the vessel can be supplied to the process because the vacuum pump pulls the contents from the vessel down to about 1 torr. In addition, the gas can be provided at a constant supply pressure, while providing a safe gas storage vessel, since the supply gas is never stored at a pressure above one atmosphere absolute.

Abstract: A valve for use with an ultra high purity gas comprising a valve body defining a valve chamber having a valve outlet through which gas is discharged and containing a reciprocable sealing member, characterized in that the valve chamber is in fluid communication with a source of the gas and in that the sealing member is reciprocable along an axis substantially parallel to the direction of flow of gas discharged from the valve outlet and into and out of sealing contact with a sealing face located within the valve chamber and circumscribing the inlet end of a valve outlet pipe, the opposite, outlet end of which pipe forms the valve outlet. The valve has a low wetted area and is thus easy to purge, and the valve design both reduces wear and restricts it to a single component which is easily replaced when necessary.
