Abstract
Abstract An apparatus for generating a gas jet of high velocity along a jet axis has a nozzle assembly coaxial with the axis and having a gas inlet thereon. Also provided, is an arcing chamber structure disposed adjacent to the nozzle assembly for transmitting the gas along the axis to the gas inlet. The nozzle assembly has two nozzle members one of which has a first nozzle passage coaxial with the axis and communicating with the gas inlet. The nozzle passage terminates in a nozzle opening. The two nozzle members can jointly form a second nozzle passage communicating with the gas inlet and have a nozzle outlet arrangement laterally of the jet axis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
Apparatus for generating a gas jet of high velocity along a jet axis comprising a nozzle assembly coaxial with said axis and having a gas inlet thereon, and an arcing chamber structure disposed adjacent said nozzle assembly for transmitting said gas along said axis to said gas inlet, said nozzle assembly comprising two nozzle members, one of said nozzle members having a first nozzle passage coaxial with said axis and communicating with said gas inlet, said nozzle passage terminating in a nozzle opening, said two nozzle members conjointly forming a second nozzle passage communicating with said gas inlet, and having nozzle outlet means laterally of said jet axis.
Claim 2
Dependent Claim
108 words
Apparatus for generating a gas jet of high velocity along a jet axis comprising a nozzle assembly coaxial with said axis and having a gas inlet thereon, and an arcing chamber structure disposed adjacent said nozzle assembly for transmitting said gas along said axis to said gas inlet, said nozzle assembly comprising two nozzle members, one of said nozzle members having a first nozzle passage coaxial with said axis and communicating with said gas inlet, said nozzle passage terminating in a nozzle opening, said two nozzle members conjointly forming a second nozzle passage communicating with said gas inlet, and having nozzle outlet means laterally of said jet axis.
Claim 3
Dependent Claim
45 words
In apparatus according to claim 1, said nozzle outlet means forming a chamber around said axis and around said first nozzle passage, whereby the gas issuing from said outlet means acts as a jet-type pump upon the axial gas flow through said arcing chamber structure.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 2, said outlet means comprising at least one exit port disposed radially of said gas jet.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 3, said outlet means comprising a plurality of exit ports disposal radially of said gas jet, and valve means for adjusting the width of at least one of said exit ports.
Claim 6
Dependent Claim
38 words
Apparatus according to claim 4, said valve means including a slidable member, cool air supply means connected to at least one of said exit ports for supplying cool air for protecting the sealing capability of said slidable member.
Claim 7
Dependent Claim
49 words
Apparatus for generating a gas jet of high velocity comprising a nozzle member, and an arcing chamber for transmitting the gas to the inlet of said nozzle member, the latter comprising two nozzle portions concentric with each other and defining an inner opening through which said gas jet exits.
Claim 8
Dependent Claim
49 words
Apparatus for generating a gas jet of high velocity comprising a nozzle member, and an arcing chamber for transmitting the gas to the inlet of said nozzle member, the latter comprising two nozzle portions concentric with each other and defining an inner opening through which said gas jet exits.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 6, said inner opening being adapted to have the form of a Laval nozzle.
Claim 10
Dependent Claim
24 words
Apparatus according to claim 6, said two nozzle portions defining a ring-like outer opening having a section corresponding to that of a Laval nozzle.
Claim 11
Dependent Claim
27 words
Apparatus according to claim 8, said apparatus comprising outlet means communicating with said outer opening for venting at least a portion of the gas of said jet.
Claim 12
Dependent Claim
22 words
Apparatus according to claim 6, at least one of said two nozzle portions being movable along the axis of said gas jet.
