A floating equipment, for injection of a gas into liquid effluents or waste water, and more particularly of a gas rich in oxygen into a basin from the surface, including the following elements:

Equipment for injecting a gas into a cesspool

The invention relates to a device for storing articles in a controlled atmosphere, comprising: at least one storage module capable of receiving the articles to be stored; a storage module provided with at least one shelf for positioning the articles, the storage module having a substantially parallelepiped shape, and having two substantially vertical and opposite walls between which the shelves extend, wherein the device is characterized in that shutters are provided, each shutter being positioned opposite one of the shelves, and between one of the two walls and the shelf in question, so as to prevent the gas from flowing vertically at the location of a shutter, and to allow the gas to flow only transversely along the shelf associated with the shutter in question.

Device for storing articles in controlled atmosphere

The invention relates to floating equipment, for injection of a gas into liquid effluents or waste water, and more particularly of a gas rich in oxygen into a basin from the surface. The floating equipment has the following elements: a driving device, intended to be disposed over the liquid, provided with a vertical output shaft (), equipped at its end with a propeller () immersed in the liquid; a pre-mixing device () comprising an injection device () positioned above or below a mobile aerator () with inclined blades, the propeller being situated at the end of the shaft, under the pre-mixing reactor.

Nitrogen monoxide composition for use as a drug

A method for treating or preventing ischemia comprising administering to a patient by an intravascular route a gaseous mixture comprising nitric oxide (NO) and carbon dioxide (CO.sub.2), wherein the nitric oxide is present in an amount effective to treat or prevent ischemia. A gaseous mixture for treatment or prevention of ischemia comprising:

Injectable NO/CO.sub.2 gaseous mixture

The mouthpiece (2) of a respirator (1) is connected to a bottle (8) of a gaseous mixture containing nitric oxide by a line (10) comprising an electrovalve (18) controlled (17) by a signal representing a supply (7, 15, 12) of a flow of respiratory mixture by the respirator (1). The installation is controlled so as to supply, upon inhalation, a gaseous mixture comprising between 21 and 100% of oxygen and between 10 and 50 ppm of nitric oxide.

Nitric oxide ventilation arrangement and method

Apparatus and process for injection of a gas, preferably carbon dioxide, comprising a source of the gas connected to at least two conduits (C) each provided with a control valve (EV) and a control (Q) of the gaseous flow rate. All of the conduits (C) open into a single channel (B), provided with a three-way control valve (V). The control (Q) of the gaseous flow rate is a calibrated orifice. The control valve (EV) and three-way control valve (V) are electrovalves. The channel (B) is connected to a catheter for injection of the gas into a body. The controls (Q) each permit a different flow rate through the associated control valve (EV), whereby a range of total flow rates of gas into the channel can be achieved by opening and closing selected ones of the controls.

Apparatus and process for injection of a gas

The process comprises circulation in a vessel containing the germs during a time T.sub.1 a ternary gas mixture comprising about 5% carbon dioxide, between 3.5 and 5% hydrogen; the balance consisting of nitrogen, followed by sealingly closing the vessel containing this gas mixture, advantageously under a slight overpressure, these operations are carried out automatically by means of an assembly comprising a gas feeding line and a gas outlet line each provided with an electro-valve and being electronically controlled.
