Abstract: A borehole apparatus capable of autonomously estimating its position in a borehole and controlling the actions of a downhole tool located in the borehole. The apparatus comprising a body, at least one measurement device capable of measuring a parameter of the borehole or the distance traveled by the device, a computer system located in the body, and a power system. The computer system comprises a processor arranged to receive data from the at least one measurement device and to calculate the position of the apparatus in the borehole, and a data storage device capable of storing data that have been processed by the processor and for storing instructions to control the actions of the downhole tool.

Abstract: A package for a solid stick product, including barrel for containing the stick product and, provided within the barrel, a product support member for supporting the stick product thereon. The product support member is movable in the longitudinal direction of the barrel for raising and lowering the stick product. The barrel has a longitudinally extending slot through a wall thereof. An adjustment button is provided on the outside of the barrel and is movable in the longitudinal direction of the barrel generally over the slot area. A tab extends through the slot and connects the adjustment button to the product support member, whereby movement of the adjustment button outside the barrel brings about an equivalent translational movement of the product support member and, therefore, the stick product within the barrel. Thus, by raising or lowering the adjustment button outside the barrel, the user can raise or lower the stick product to extract the product from or retract the product within the barrel.
