Title Method and apparatus for sampling a core of tar sand
Date 1983-02-08
Description The invention provides a method and apparatus for sampling a frozen core of tar sand. The frozen core is first cut transversely along its length to form a pair of slabs of semi-circular cross-section. A longitudinal sample portion of substantially triangular cross-section is then cut from the central portion of the still frozen slab. The triangular sample portion is ground in a cryogenic grinder to produce a finely divided, substantially homogeneous material from which small representative sub-samples may be obtained. The triangular sample portion is cut from the slab by a pair of angularly disposed circular saws carried along the length of the slab. The slab is supported and held by cradle means which fix the flat face of the slab in a predetermined plane. The longitudinal sample portion thus formed has a triangular cross-section of substantially constant cross-sectional area.
