  • Patent number: 3968995
    Abstract: A drive chain for transmitting power to a rotatable cutter head of a mining machine. The mining machine is of the type having a rotary cutter drum mounted at the forward end of the mining machine frame. The cutter drum has helical auger flights with cutter bits mounted on their periphery. Electric motors are provided on either side of the mining machine to provide power for rotating the cutter drum. A drive and cutter chain transmits the power from each electric motor to the rotary drum. The drive chain comprises roller chain links with offset sidebars. Each drive chain is relatively narrow having but a single row of links. Some of the links are cutter links which carry cutter bits. Selected portions of the cutter links and the sprockets are cut away to prevent entrapment and build up of foreign matter.

  • Patent number: 3965983
    Abstract: Pump-off control apparatus for preventing cavitation of a sub-surface pump which provides artificial lift for fluid produced from a fluid bearing strata located downhole in a borehole. A sound wave is focused downhole and travels down the casing annulus where it strikes the liquid surface and rebounds to a receiver located near the well head. The time lapse of the traveling wave is used to measure the relative location of the liquid surface relative to the pump inlet, thereby enabling the control apparatus to shut-in a well before it can encounter a pump-off condition which can cause fluid pounding.

  • Patent number: 3964547
    Abstract: A method of producing highly viscous oil from an underground formation penetrated by a well. Steam is injected through a first channel into the lower part of the formation. At the same time, previously recovered oil from the formation is injected through the well in a channel surrounding the steam channel to the upper part of the formation. This native oil insulates the formation from the steam and also serves to block the steam from rising in the formation. The heated oil can then be recovered from an adjacent well or injection can be stopped and the oil can be recovered from the well through which the fluid was injected.
