Abstract
Abstract A nozzle arrangement comprising concentric inner and outer cylinders and a jacket fitting tightly around the outer cylinder. The inner and outer cylinders have longitudinal fluid exits and are relatively rotatable. A knob located outside the outer cylinder is connected by a shaft to the inner cylinder to permit it to be rotatably adjusted relative to the outer cylinder. The jacket has an elongated slot that serves to regulate the flow through the exit of the outer cylinder.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
141 words
A nozzle arrangement comprising: a first cylinder adapted at one end to be connected to a source of fluid, the first cylinder having an exit for fluid arranged in a line along its length; a second cylinder having an exit for fluid arranged in a line along its length, the second cylinder surrounding the first cylinder in concentric spaced relationship therewith such that the outer wall of the first cylinder and the inner wall of the second cylinder define an annular chamber for fluid flow between the exits of the cylinders; means for supporting the first and second cylinders in relatively rotatable relationship to each other; an adjusting element located outside the second cylinder; and means for coupling the adjusting element to the first cylinder to permit rotation of the first cylinder relative to the second cylinder by the adjusting element.
Claim 2
Dependent Claim
141 words
A nozzle arrangement comprising: a first cylinder adapted at one end to be connected to a source of fluid, the first cylinder having an exit for fluid arranged in a line along its length; a second cylinder having an exit for fluid arranged in a line along its length, the second cylinder surrounding the first cylinder in concentric spaced relationship therewith such that the outer wall of the first cylinder and the inner wall of the second cylinder define an annular chamber for fluid flow between the exits of the cylinders; means for supporting the first and second cylinders in relatively rotatable relationship to each other; an adjusting element located outside the second cylinder; and means for coupling the adjusting element to the first cylinder to permit rotation of the first cylinder relative to the second cylinder by the adjusting element.
Claim 3
Dependent Claim
18 words
The nozzle arrangement of claim 1, in which the exits are pluralities of openings arranged in a line.
Claim 4
Dependent Claim
31 words
The nozzle arrangement of claim 2, in which the plurality of openings in the first cylinder increase in size moving away from the end adapted to be connected to the source.
Claim 5
Dependent Claim
21 words
The nozzle arrangement of claim 1, in which means are provided for blocking part of the exit in the second cylinder.
Claim 6
Dependent Claim
20 words
The nozzle arrangement of claim 4, in which the blocking means is adjustable to vary the extent of exit blocking.
Claim 7
Dependent Claim
44 words
The nozzle arrangement of claim 4, in which the blocking means is a jacket fitting snugly around the outer surface of the second cylinder, the jacket having a slot along its length through which fluid is ejected from the exit in the second cylinder.
Claim 8
Dependent Claim
16 words
The nozzle arrangement of claim 6, in which the edges of the slot are tapered inwardly.
Claim 9
Dependent Claim
88 words
A nozzle arrangement comprising: an inner cylinder having an exit arranged along its length; an outer cylinder having an exit arranged along its length, the outer cylinder being concentric with the inner cylinder and spaced therefrom to form an annular passage; the inner and outer cylinders being relatively rotatable; means for coupling fluid to the inside of the inner cylinder; and a jacket fitting tightly around the outer cylinder, the jacket having a slot along its length to regulate the flow through the exit of the outer cylinder.
Claim 10
Dependent Claim
88 words
A nozzle arrangement comprising: an inner cylinder having an exit arranged along its length; an outer cylinder having an exit arranged along its length, the outer cylinder being concentric with the inner cylinder and spaced therefrom to form an annular passage; the inner and outer cylinders being relatively rotatable; means for coupling fluid to the inside of the inner cylinder; and a jacket fitting tightly around the outer cylinder, the jacket having a slot along its length to regulate the flow through the exit of the outer cylinder.
Claim 11
Dependent Claim
19 words
The nozzle arrangement of claim 8, in which the slot is wider than the exit in the outer cylinder.
Claim 12
Dependent Claim
16 words
The nozzle arrangement of claim 8, in which the edges of the slot are inwardly tapered.
Claim 13
Dependent Claim
19 words
The nozzle arrangement of claim 8, in which the exit comprises a plurality of openings arranged in a line.
Claim 14
Dependent Claim
64 words
The nozzle arrangement of claim 1, in which the coupling means comprises a shaft extending through the outer cylinder, the ends of the shaft being connected respectively to the adjusting element and the inner cylinder, the nozzle arrangement additionally comprising means for sealing the outside of the outer cylinder from the inside of the outer cylinder where the shaft extends through the outer cylinder.
