摘要:
A sub-atmospheric gas delivery system (100) with a backflow control apparatus (10) for preventing backflow into the sub-atmospheric gas source (14). The gas delivery system includes three fluidly coupled sticks: a purge stick (120), a process gas delivery stick (124) and an evacuation stick (130). The backflow control apparatus comprises a gas line (26) fluidly coupling the sub-atmospheric gas source to a chamber (50), a valve (20) attached to the sub-atmospheric gas source for blocking fluid communication between the gas source and the gas line upon receipt of a first signal, a flow restrictor (R) in fluid communication with the gas line and positioned between the valve and the chamber, and first and second pressure transducers (P1 and P2) in fluid communication with the gas line and positioned on either side of the flow restrictor. Each transducer is capable of generating a signal representative of pressure. The backflow control apparatus further includes a valve controller unit (40) connected to the first and second pressure transducers and the valve. The controller is capable of generating the aforementioned first signal in response to the signals from the first and second pressure transducers.

The invention relates to soluble metal oxides and mixed metal oxides and to solutions comprising metal oxides and mixed metal oxides. The invention further relates to a process for preparing a soluble metal oxide and a soluble mixed metal oxide and additionally relates to a process for modifying the solubility of a soluble metal oxide. The metal oxides, mixed metal oxides and solutions thereof have a number of applications and in particular are suitable for use as catalysts and also as precursors for the formation of metal oxide coatings. The present invention is also suitable for coating medical devices, and can be used for coating drug cocktails to produce sustained release tablets. Similarly, the coatings may be used for the sustained release of pesticides, insecticides, dyes and fragrances. Further uses include the application of the present invention to coat the moving parts of engines and machinery. Furthermore the present invention has application as use as spacer layers in Metal Enhanced Fluorophores (sensing platforms).

In one example form, the present invention relates to a decal for treating a surface. The decal includes a web and an agent for treating the surface. The agent is attached to the web. The decal further includes a bonding material that attaches the decal to the surface. The bonding material is also attached to the web. In some embodiments, the agent may be attached to the web while in other embodiments the agent may form part of the web. In addition, the agent may be at least partially, or wholly, soluble in the web, or may be suspended in the web. In another form, the present invention relates to a method of treating a surface. The method includes attaching a decal to the surface and treating the surface with the decal. Attaching a decal to the surface may include adhering the decal to the surface with an adhesive.
摘要:
The present invention relates to a spot cleaner that includes a first absorbent pad and a second absorbent pad. The first absorbent pad includes a cleaner. The spot cleaner further includes a moisture proof barrier that is between the first absorbent pad and the second absorbent pad. The moisture proof barrier encloses the first absorbent pad to keep the cleaner inside the moisture proof barrier. In some embodiments, the moisture proof barrier has a first layer that is attached to the first absorbent pad and a second layer that is attached to the second absorbent pad. The first and second layers of the moisture proof barrier may be separable to allow a hand to be inserted between the first and second layers so that the hand is able to manipulate the spot cleaner without any portion of the spot or cleaner contacting the hand.
