Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
96 words
A device of the kind described comprising: a housing, a pair of means disposed in said housing and having entrances for substantially simultaneously receiving samples of molten metal, a first thermocouple extending transversely through one of said receiving means, tubular means extending alongside at least one of said receiving means, and a second thermocouple carried by a lower end of said tubular means and spaced from said pair of receiving means and entrances thereto whereby the temperature of metal initially received in the device may be recorded in advance of that offered through tHe first thermocouple.
Claim 2
Independent Claim
96 words
A device of the kind described comprising: a housing, a pair of means disposed in said housing and having entrances for substantially simultaneously receiving samples of molten metal, a first thermocouple extending transversely through one of said receiving means, tubular means extending alongside at least one of said receiving means, and a second thermocouple carried by a lower end of said tubular means and spaced from said pair of receiving means and entrances thereto whereby the temperature of metal initially received in the device may be recorded in advance of that offered through tHe first thermocouple.
Claim 3
Dependent Claim
28 words
The device defined in claim 1, including means for temporarily protecting said entrances and said second thermocouple when the device is dipped into a bath of molten metal.
Claim 4
Dependent Claim
34 words
The device defined in claim 1, including means for supporting said second thermocouple, and said receiving means and said supporting means are fixedly secured in a mass of cement in a substantially parallel relationship.
Claim 5
Dependent Claim
29 words
The device defined in claim 1, including a mass of cement, means for supporting said second thermocouple, and said supporting means is embedded in said mass and extends therethrough.
Claim 6
Dependent Claim
51 words
The device defined in claim 1, in which said receiving means is located substantially within the confines of said housing, said second thermocouple has a portion thereof located externally of said housing, including means for temporarily protecting said external portion when the device is dipped into a bath of molten metal.
Claim 7
Dependent Claim
66 words
The device defined in claim 1, including first conductor means connected to said first thermocouple for extension outwardly from said housing for connection with a first recording apparatus, and second conductor means connected to said thermocouple for extension outwardly from said housing through said tubular means for connection with a second recording apparatus which is responsive to said second thermocouple in advance of said first thermocouple.
Claim 8
Dependent Claim
29 words
The device defined in claim 1, including a mass of cement, and means embedded in said mass for supporting said second thermocouple in fixed relation to said receiving means.
Claim 9
Dependent Claim
35 words
The device defined in claim 1, including means for supporting said second thermocouple, and means surrounding portions of said receiving means and said supporting means for fixedly positioning the same in relation to said housing.
Claim 10
Dependent Claim
50 words
The device defined in claim 1, including means for supporting said second thermocouple, a mass of cement, portions of said receiving means and said supporting means are disposed in said mass, and tubular means surrounds said receiving means and said supporting means which assists in holding the same in place.
Claim 11
Dependent Claim
35 words
The device defined in claim 1, including means for supporting said second thermocouple, and a mass of cement which is common to and serves to anchor said receiving means and said supporting means in place.
Claim 12
Independent Claim
78 words
A device of the kind described: a housing, a pair of recessed members disposed in said housing and forming a chamber for receiving a sample of molten metal, tubular means extending transversely through said chamber, a first thermocouple extending through said tubular means, and a second thermocouple disposed at a location spaced from said receiving means whereby the temperature of metal initially received in the device may be recorded in advance of that offered by the first thermocouple.
Claim 13
Independent Claim
78 words
A device of the kind described: a housing, a pair of recessed members disposed in said housing and forming a chamber for receiving a sample of molten metal, tubular means extending transversely through said chamber, a first thermocouple extending through said tubular means, and a second thermocouple disposed at a location spaced from said receiving means whereby the temperature of metal initially received in the device may be recorded in advance of that offered by the first thermocouple.
Claim 14
Dependent Claim
32 words
The device defined in claim 11, including means for supporting said second thermocouple, and a mass of cement fixedly secures said receiving means and said supporting means in a substantially parallel relationship.
Claim 15
Dependent Claim
29 words
The device defined in claim 11, including a mass of cement, means for supporting said second thermocouple, and said supporting means is embedded in said mass and extends therethrough.
Claim 16
Dependent Claim
51 words
The device defined in claim 11, in which said receiving means is located substantially within the confines of said housing, said second thermocouple has a portion thereof located externally of said housing, including means for temporarily protecting said external portion when the device is dipped into a bath of molten metal.
Claim 17
Dependent Claim
63 words
The device defined in claim 11, including first conductor means connected to said first thermocouple for extension outwardly from said housing for connection with a first recording apparatus, and second conductor means connected to said second thermocouple for extension outwardly from said housing for connection with a second recording apparatus which is responsive to said second thermocouple in advance of said first thermocouple.
Claim 18
Dependent Claim
35 words
The device defined in claim 11, including means for supporting said second thermocouple, and means surrounding portions of said receiving means and said supporting means for fixedly positioning the same in relation to said housing.
Claim 19
Dependent Claim
50 words
The device defined in claim 11, including means for supporting said second thermocouple, a mass of cement, portions of said receiving means and said supporting means are disposed in said mass, and tubular means surrounds said receiving means and said supporting means which assists in holding the same in place.
Claim 20
Independent Claim
154 words
A device for obtaining samples of molten metal comprising: a housing having a chamber and provided with means forming a lower chamber, a pair of receiving means having upper and lower portions, means for securing said lower portions to said housing chamber so that said upper portions extend into said housing chamber in a juxtaposed relationship, said receiving means being respectively provided with entrances communicating with said lower chamber whereby when the device is dipped into a bath of molten metal samples thereof will flow through said entrances from said lower chamber into said receiving means and when the device is removed from the bath the samples will solidify, tubular means extending transversely through the upper portions of one of said receiving means, a first thermocouple extending through said tubular means and carried thereby, and a second thermocouple structure disposed alongside one of said receiving means with a portion thereof extending below said entrances.
Claim 21
Independent Claim
154 words
A device for obtaining samples of molten metal comprising: a housing having a chamber and provided with means forming a lower chamber, a pair of receiving means having upper and lower portions, means for securing said lower portions to said housing chamber so that said upper portions extend into said housing chamber in a juxtaposed relationship, said receiving means being respectively provided with entrances communicating with said lower chamber whereby when the device is dipped into a bath of molten metal samples thereof will flow through said entrances from said lower chamber into said receiving means and when the device is removed from the bath the samples will solidify, tubular means extending transversely through the upper portions of one of said receiving means, a first thermocouple extending through said tubular means and carried thereby, and a second thermocouple structure disposed alongside one of said receiving means with a portion thereof extending below said entrances.
