Abstract: Disclosed is a device for supplying therapeutic gas, notably NO/N2 or O2/N2O mixtures, including an internal passage with a valve for conveying and controlling the flow of therapeutic gas in the internal passage, a control unit controlling the valve, a graphic display for displaying choices that can be selected by a user, and a selector, such as touch-sensitive keys displayed on the graphic display for making a selection from among the selectable choices displayed on the graphic display. The control unit is configured to count a total number of patients treated by administration of the therapeutic gas from the selection, by a user, via the selector, of a first given choice corresponding to the start of a treatment by administering the therapeutic gas to a patient concerned.

Abstract: A single-component exchanger-reactor including, from bottom to top in the direction of manufacture a distribution region, an inlet connector and an outlet connector, each in the form of a half cylinder and adjoining the distribution region on either side; an inlet located on the front face of the inlet connector, an outlet located on the front face of the outlet connector; an exchange region consisting of reactive channels and product channels; with each connector including supports in the inner upper part thereof.

Abstract: Group 4 transition metal-containing film forming compositions comprising Group 4 transition metal precursors having the formula: wherein M is Ti, Zr, or Hf; each E is independently C, Si, B or P; m and n is independently 0, 1 or 2; m+n>1; o and p is independently 0, 1 or 2; o+p>1; each R is independently hydrogen or or a C1-C4 hydrocarbon group; each L is independently a ?1 anionic ligand selected from the group consisting of NR?2, OR?, Cp, amidinate, ?-diketonate or keto-iminate, wherein R? is a H or a C1-C4 hydrocarbon group; and each L? is independently NR? or O, wherein R? is a H or a C1-C4 hydrocarbon group. Also disclosed are methods of synthesizing and using the disclosed precursors to deposit Group 4 transition metal-containing films on one or more substrates via vapor deposition processes.

Abstract: The invention relates to a method for producing power from at least one fuel, said method including: a step of oxidizing said fuel by means of placing it in contact with at least one oxygen loaded solid compound and of concomitantly reducing said solid compound.

Abstract: Auxiliary gas is withdrawn from the heat exchanger during cooling or reheating at an intermediate temperature which is close to the vaporizing temperature of the oxygen or nitrogen high pressure product stream, then compressed by a cold compressor and reintroduced in the heat exchanger. The invention is particularly applicable to the production of gaseous oxygen at a pressure greater than about 15 bar.

Abstract: The gas originating from the expansion during the stage (T.sub.6) is directed into a buffer tank and each adsorber has an operating cycle delayed by 1/nth of the cycle period (T) with respect to a preceding one, and each production stage has a duration of (x/n)T, "n" being greater than or equal to 6, and "x" greater than or equal to 2, and each expansion stage at an intermediate pressure has a shorter duration than each elution stage.
