Abstract
Abstract The device includes a probe for performing a measuring, sampling, or treating operation on a bath of molten metal in a receptacle. A probe-carrier movably mounted on a support structure allows insertion of the probe into the receptacle, and its withdrawal. The following sequence of operations is carried out automatically by the device: insertion of the probe; arrest of the probe, during insertion, when the probe is at a predetermined position relative to the surface of the bath; and withdrawal of the probe when a predetermined length of time has elapsed since arresting of the probe.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
A device for carrying out a measuring, sampling, or treating operation upon a bath of molten metal in a receptacle, the device comprising: a. a probe for performing a measuring, a sampling, or treating operation: b. a carrier on which the probe is mounted; c. a support structure on which the probe-carrier is movably mounted, movement of the probe-carrier allowing the insertion of the probe into the receptacle and its withdrawal from the receptacle; d. automatic means for inserting the probe into the receptacle by motion of the probe-carrier; e. automatic means for arresting the motion of the probecarrier, during insertion, when the probe is at a predetermined position relative to the surface of the bath in the receptacle, the automatic arresting means including means for locating the surface of the bath, arranged to move conjointly with the probe; and f. automatic means for withdrawing the probe from the receptacle by motion of the probe-carrier when a predetermined length of time has elapsed since the arresting of the motion of the probe-carrier during insertion.
Claim 2
Independent Claim
174 words
A device for carrying out a measuring, sampling, or treating operation upon a bath of molten metal in a receptacle, the device comprising: a. a probe for performing a measuring, a sampling, or treating operation: b. a carrier on which the probe is mounted; c. a support structure on which the probe-carrier is movably mounted, movement of the probe-carrier allowing the insertion of the probe into the receptacle and its withdrawal from the receptacle; d. automatic means for inserting the probe into the receptacle by motion of the probe-carrier; e. automatic means for arresting the motion of the probecarrier, during insertion, when the probe is at a predetermined position relative to the surface of the bath in the receptacle, the automatic arresting means including means for locating the surface of the bath, arranged to move conjointly with the probe; and f. automatic means for withdrawing the probe from the receptacle by motion of the probe-carrier when a predetermined length of time has elapsed since the arresting of the motion of the probe-carrier during insertion.
Claim 3
Dependent Claim
97 words
A device as claimed in claim 1, including a double-acting piston-and-cylinder arrangement mounted on the support structure and linked to the probe-carrier so that motion of the piston relative to the cylinder causes motion of the probe-carrier; means for supplying fluid under pressure to one side of the piston; means for supplying fluid under pressure to the other side of the piston; means for draining fluid from the said one side; means for draining fluid from the said other side; and means for controlling the rate at which fluid is supplied to and drained from the cylinder.
Claim 4
Dependent Claim
112 words
A device as claimed in claim 1, in which the automatic means for arresting the motion of the probe-carrier comprises: i. a tube arranged to move conjointly with the probe so as to be inserted into the receptacle with the probe, one end of the tube being open, the other end being connected to a source of fluid under pressure; ii. automatic means for detecting and increase in pressure within the tube due to the closure of the open end of the tube by the bath; and iii. automatic means for arresting the motion of the probe-carrier in response to the detection of the increase in pressure by the automatic detecting means.
Claim 5
Dependent Claim
106 words
A device as claimed in claim 1, in which the automatic means for arresting the motion of the probe-carrier comprises: i. a tube arranged to move conjointly with the probe so as to be inserted into the receptacle with the probe, one end of the tube being open; ii. automatic means connected to the other end of the tube to detect an increase in pressure within the tube as a result of the entry of the bath by the tube; and iii. automatic means for arresting the motion of the probe-carrier in response to the detection of the increase in pressure by the automatic detecting means.
Claim 6
Dependent Claim
31 words
A device as claimed in claim 4, in which the end of the tube which enters the bath comprises material which evolves gas when it comes into contact with the bath.
Claim 7
Dependent Claim
42 words
A device as claimed in claim 1, in which the automatic withdrawing means is operatively connected with the automatic arresting means via delay means arranged to introduce a predetermined delay between the arresting of the probe and the withdrawal of the probe.
Claim 8
Dependent Claim
35 words
A device as claimed in claim 1, in which the automatic withdrawing means move the prove to a position which is the same as its initial position before the operation of the automatic inserting means.
Claim 9
Dependent Claim
14 words
A device as claimed in claim 1, in which the various means operate pneumatically.
Claim 10
Dependent Claim
19 words
A device as claimed in claim 1, further comprising manually operable means for arresting the motion of the probe-carrier.
Claim 11
Dependent Claim
16 words
A device as claimed in claim 1, further comprising manually operable means for moving the probe-carrier.
