Abstract
Abstract A cooling arrangement for use in a machine for treating a thermoplastic material, especially molten glass, for cooling a split forming tool, parts of which are mounted on the machine for pivoting about a first pivoting axle, by a pressurized cooling fluid, especially air, includes at least one supply conduit stationarily mounted on the machine and operative for supplying the cooling fluid, and at least one articulated connecting conduit extending between the supply conduit and a respective fluid distributing means mounted for joint pivoting with the forming tool parts about the first pivoting axle, each articulated connecting conduit having at least two components one of which is pivotally mounted on a second pivoting axle arranged at the supply conduit, and the other of which is connected to the one component by a third pivoting axle for relative pivoting and is pivotally mounted on the fluid distributing means for pivoting relative thereto by a fourth pivoting axle, the first, second, third and fourth pivoting axles being parallel to one another. Sealing gap forming seals may be used for sealing the articulated conduit components, the supply conduit, and the fluid distributing means with respect to one another when the cooling fluid is a low-pressure gaseous fluid.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
A cooling arrangement for use in a machine for treating a thermoplastic material, especially molten glass, for cooling a split forming tool, parts of which are mounted on the machine for pivoting about a first pivoting axle, by a pressurized cooling fluid, especially air, comprising at least one supply conduit stationarily mounted on the machine for supplying the cooling fluid; at least one fluid distributing means mounted for joint pivoting with the forming tool parts about said first pivoting axle; and at least one articulated connecting conduit each including at least two components which are respectively pivotable relative to said supply conduit and to said fluid distributing means and which are pivotable relative to one another.
Claim 2
Dependent Claim
116 words
A cooling arrangement for use in a machine for treating a thermoplastic material, especially molten glass, for cooling a split forming tool, parts of which are mounted on the machine for pivoting about a first pivoting axle, by a pressurized cooling fluid, especially air, comprising at least one supply conduit stationarily mounted on the machine for supplying the cooling fluid; at least one fluid distributing means mounted for joint pivoting with the forming tool parts about said first pivoting axle; and at least one articulated connecting conduit each including at least two components which are respectively pivotable relative to said supply conduit and to said fluid distributing means and which are pivotable relative to one another.
Claim 3
Dependent Claim
113 words
The cooling arrangement as defined in claim 1, wherein said articulated connecting conduit includes a first and a second of said components; and further comprising means for pivotably mounting said components, including a second pivoting axle parallel to the first pivoting axle and stationarily mounted on the machine at said supply conduit for pivotably mounting said first component thereat, a third pivoting axle parallel to said first and second pivoting axles and interposed between said components for pivotably connecting the same to one another, and a fourth pivoting axle parallel to said first, second and third pivoting axles and stationary relative to said fluid distributing means for pivotably mounting said second component thereat.
Claim 4
Dependent Claim
58 words
The cooling arrangement as defined in claim 1 for use with a gaseous cooling fluid, further comprising means for sealing said components with respect to one another and with respect to said supply conduit and said fluid distributing means, respectively, comprising means for bounding respective sealing gaps between said components, said supply conduit, and said fluid distributing means.
Claim 5
Dependent Claim
32 words
The cooling arrangement as defined in claim 1, and further comprising an extension element of a selected length interposable between said supply conduit and the adjoining component of said articulated connecting conduit.
Claim 6
Dependent Claim
33 words
The cooling arrangement as defined in claim 1, and further comprising an extension element of a selected length interposable between said fluid distributing means and the adjoining component of said articulated connecting conduit.
Claim 7
Dependent Claim
128 words
The cooling arrangement as defined in claim 1, wherein said articulated connecting conduit includes a first and a second of said components; further comprising means for pivotably mounting said components, including second, third and fourth pivoting axles parallel to the first pivoting axle, having respective longitudinal axes, and respectively interposed between said supply conduit and said first component, between said components, and between said second component and said fluid distributing means; and wherein said pivoting axles are so arranged and said components so dimensioned that a plane defined by the longitudinal axes of said second and third pivoting axles always encloses an angle with a plane defined by the longitudinal axes of said third and fourth pivoting axles which is at least 0° and is less than 180°.
Claim 8
Dependent Claim
54 words
The cooling arrangement as defined in claim 6, wherein said pivoting axles are so arranged and said components so dimensioned that the longitudinal axis of said third pivoting axle is always situated outwardly of the trajectory of movement of the longitudinal axis of said fourth pivoting axle as considered from the first pivoting axle.
Claim 9
Dependent Claim
47 words
The cooling arrangement as defined in claim 7, wherein said pivoting axles are so arranged and said components so dimensioned that the longitudinal axis of said second pivoting axle is also situated outwardly of the trajectory of movement of the longitudinal axis of said fourth pivoting axle.
Claim 10
Dependent Claim
54 words
The cooling arrangement as defined in claim 6, wherein said pivoting axles are so arranged and said components so dimensioned that the longitudinal axis of said third pivoting axle is always arranged inwardly of the trajectory of movement of the longitudinal axis of said fourth pivoting axle as considered from the first pivoting axle.
Claim 11
Dependent Claim
47 words
The cooling arrangement as defined in claim 9, wherein said pivoting axles are so arranged and said components so dimensioned that the longitudinal axis of said second pivoting axle is also situated inwardly of the trajectory of movement of the longitudinal axis of said fourth pivoting axle.
Claim 12
Dependent Claim
98 words
The cooling arrangement as defined in claim 1, wherein said articulated connecting conduit includes a first and a second of said components; further comprising means for pivotably mounting said components, including second, third and fourth pivoting axles parallel to the first pivoting axle and respectively interposed between said supply conduit and said first component, between said components, and between said second component and said fluid distributing means; and wherein said first component has an inlet opening permanently communicating with said supply conduit and an outlet opening concentric with said third pivoting axle and communicating with said inlet opening.
Claim 13
Dependent Claim
23 words
The cooling arrangement as defined in claim 11, wherein said inlet opening extends about a partly annular course about said second pivoting axle.
Claim 14
Dependent Claim
