Abstract
Abstract A molten metal sampling apparatus and method of the type in which a sample receiving means is positioned in the end of a cardboard tube intended to be dipped into a body of molten metal. The molten metal after disintegrating an external protective cap flows through a tortous path and divides into two passageways before solidifying in a receiving chamber to form a solid sample. One receiver in each sampling device is provided with a temperature measuring means so that the temperature changes of the sample may be measured.

Claim 73
Independent Claim
111 words
A device for obtaining samples of molten metal comprising: a housing, receiving means, means for supporting said receiving means in said housing, means providing a chamber, a first passage communicating with said receiving means and said chamber and a second passage communicating with said chamber, a thermocouple disposed in said second passage, the arrangement being such that when the device is dipped into a bath of molten metal some of the latter will flow into said first passage via said chamber into said receiving means and into said second passage to activate said thermocouple and when the device is removed from thE bath the metal received will solidify to produce samples.
Claim 74
Independent Claim
111 words
A device for obtaining samples of molten metal comprising: a housing, receiving means, means for supporting said receiving means in said housing, means providing a chamber, a first passage communicating with said receiving means and said chamber and a second passage communicating with said chamber, a thermocouple disposed in said second passage, the arrangement being such that when the device is dipped into a bath of molten metal some of the latter will flow into said first passage via said chamber into said receiving means and into said second passage to activate said thermocouple and when the device is removed from thE bath the metal received will solidify to produce samples.
Claim 75
Independent Claim
123 words

Claim 81
Independent Claim
92 words
A device of the kind described comprising: a housing, means mounted in said housing forming a chamber for receiving a sample of molten metal, means disposed in said housing forming a second chamber for receiving molten metal, a pair of passages communicatively connecting said chambers so tat when the device is dipped into a bath of molten metal some of the latter will flow through one of the chambers into the other chamber via said passages, and a thermocouple having at least a portion thereof disposed centrally in one of said chambers.
Claim 82
Independent Claim
92 words
A device of the kind described comprising: a housing, means mounted in said housing forming a chamber for receiving a sample of molten metal, means disposed in said housing forming a second chamber for receiving molten metal, a pair of passages communicatively connecting said chambers so tat when the device is dipped into a bath of molten metal some of the latter will flow through one of the chambers into the other chamber via said passages, and a thermocouple having at least a portion thereof disposed centrally in one of said chambers.
