Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
61 words
In apparatus for testing molten metal by lowering a measuring or sampling probe to a desired depth in the molten metal, the apparatus comprising a probe, an elongate probe-carrier, a support structure on which the probe-carrier is tiltably mounted, and means for lowering and raising the probe-carrier: the improvement that the probe-carrier is telescopic, its length being adjustable between given limits.
Claim 2
Dependent Claim
61 words
In apparatus for testing molten metal by lowering a measuring or sampling probe to a desired depth in the molten metal, the apparatus comprising a probe, an elongate probe-carrier, a support structure on which the probe-carrier is tiltably mounted, and means for lowering and raising the probe-carrier: the improvement that the probe-carrier is telescopic, its length being adjustable between given limits.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1, in which the telescopic probe-carrier comprises a rear part rigid with the support structure, and a movable front part, both parts being tubular, the front part running inside the rear part.
Claim 4
Dependent Claim
19 words
The apparatus of claim 2, in which the probe-carrier includes rollers interposed between the said front and rear parts.
Claim 5
Dependent Claim
38 words
The apparatus of claim 2, in which, when the probe-carrier is adjusted to its minimum length, the length of the front part which lies inside the rear part is shorter than the total length of the rear part.
Claim 6
Dependent Claim
49 words
The apparatus of claim 1, in which the probe-carrier has a front part and a rear part, the apparatus further comprising a motor mounted on one said part, and a winding line connected between the motor and the other said part, whereby the length of the probe-carrier is adjustable.
Claim 7
Dependent Claim
13 words
The apparatus of claim 5, in which the motor is a pneumatic motor.
Claim 8
Dependent Claim
19 words
