Abstract: A method of continuously recovering hydrocarbons from carbon ores can include providing first and second vessels containing rubblized carbon ore. A cooling fuel gas can be introduced into the first vessel. The cooling fuel gas can include oxygen and a recycle gas from the second vessel, which includes hydrocarbons and oxidation products. The oxygen can be consumed through oxidation in an oxidation zone in the first vessel. The temperature of the oxidation zone can be controlled by limiting the oxygen concentration in the cooling fuel gas. This can produce a hot oxidation product gas that heats rubblized carbon ore in a pyrolysis zone downstream of the oxidation zone. Gaseous and vapor hydrocarbons can be produced in the pyrolysis zone. The vapor hydrocarbons can be condensed in a condensing zone downstream of the pyrolysis zone and then collected. The remaining gaseous hydrocarbons and oxidation products can be recycled as the recycle gas.

Abstract: Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.

Abstract: A cell-growing system may include a cell-growing container, a pump for controlling the pressure of the chamber of the container, a filter for maintaining the chamber sterilized, a flow control regulator for controlling the substance supplied to the cell-growing container. The cell-growing container may include an internal structure that takes the form of a reticulated structure to increase the surface area for growing cells. The cell-growing system may be used to perform cycles of cell expansion and harvest. The cell-growing system may be maintained as a closed and sterilized system through the cycles. In harvesting, a first subset of the cells can be disassociated from the cell culture while a second subset remains. The disassociated cells may be discharged to a collection container while maintaining the system closed to an external environment. The remaining cells may be used as seeds to proliferate more cells in the next cycle.
