Abstract

703,975. Core sampling tools; mining cartridges. SOC. DE PROSPECTION ELECTRIQUE, PROCEDES SCHLUMBERGER. July 14, 1952 [Aug. 1, 1951], No. 17721/52. Classes 9(1) and 85 In an apparatus in which sample taking tools 3 are projected into the boundary soils of soundings or boreholes 2 by explosive, mechanical, &c. means, the portion of the tool directly engaging the soil is provided with teeth 10. In the preferred form the tool 3 comprises a front toothed section 5 detachably secured to a rear portion 6 of lesser diameter, the section 5 being made of a harder metal than said rear portion and having its inner wall relieved at 9.
