WO2000066227B1 - Method for attenuating thermal gas flows and usmanov's device for realising the same - Google Patents

Abstract

The present invention pertains to the field of fire-fighting technology and can be used for protecting equipment and persons when extinguishing fires, for dividing the volume of buildings in surface or underground structures or installations into fire-proof compartments, for providing protection against the collapse of ceiling structures and for locating the progression of the flame front in large-scale fires resulting in ecological disasters. The purpose of this invention is to develop a method for attenuating with an improved efficiency the energy flow consisting of light, heat and convection gas flows, and to develop a device of the gun-carriage type for creating a thermal-radiation protection screen which is more reliable, harmless and easy to implement and which provides protection against light radiation and convection gas flows. This method involves creating a curtain of a cooling liquid that is sprayed into space between surfaces. When creating more than one curtain, the method involves using a combined supply of cooling liquid. One of the curtains is formed by spraying the liquid, while the following curtains are formed by supplying an aerated mechanical or chemical foam. The device includes a mounting assembly, a spraying unit as well as grids arranged on both sides of a frame so as to define a gap. Nozzles are further mounted in the openings formed in the tubes of the frame.

Explanation of Article 19

Having studied the relevant documents presented in the report, we consider it necessary to make slight changes to the formula of the invention, and namely:

1. On the basis of the invention, a change was made, which means that the thermal power supply includes electrical energy and gas-fired power. Excluding the concept of “gaseous”, we hereby exclude the rule in the title of the invention. Otherwise, from the name we exclude the special name “Usman” according to the requirements of the USC instruction. Taking into account the foregoing, we recommend that you start the first step of the invention by the following method: “Method of easing teshyuvy ...”.

2. Β π.1 of the formula introduced a review of the state of the increase in liquid (see p. 2 of the description, the last paragraph, p. 3, paragraph 1, 2, 3, 4).

3. Β 4 paragraph of the formula amended: τ.κ. The protected device is a flashing device, that is, the initial part of step 4 is the following:

“The device is used to protect the device, which includes the unit ...” and further, without changing the phrase “... the installation is established”, we take into account the neglect of the account )

4. π. 9, 10, 13, 14, τ.κ. are excluded from the formula In these paragraphs of the formula, the known materials are indicated, used for the manufacture of metal networks and the diameters of the products used in the production, are used for the manufacture of 20, 21, and 22 are both inconsequential.
