Abstract: An embodiment includes a cardiac resuscitation system with first and second electrodes in a source electrode pad and a return electrode in a return electrode pad. After the source and return electrode pads are applied to a patient the layperson may put a switch in a first position to create a first electrical path to communicate a first shock between the first and return electrodes via a first vector. If the first shock fails the user may move the switch to a second position to create a second electrical path to communicate a second shock between the second and return electrodes via a second vector. As a result, the system allows a layperson to easily flip a switch to produce a first shock via a first vector and a second shock via a second vector thereby improving therapy outcomes. Other embodiments are described herein.

Abstract: Process and apparatus are disclosed for recovering liquid and gaseous fuel from solid hydrocarbon-containing mineral material such as bitumen-containing mineral materials exemplified by tar sands or oil-bearing diatomites, without expensive pretreatment to separate the hydrocarbon containing material from material containing no hydrocarbon. The hydrocarbon-containing material is agglomerated into discrete pieces that are treated on a traveling grate such as a circular traveling grate and subjected to sequential treatments in which hot gases are passed upwardly or downwardly through a relatively deep permeable bed of the pieces on the grate, in several treating zones separated by transverse gas seals and sealed at the side edges by suitable gas seals. All, or essentially all, of the heat required is obtained in a coke burn-off zone from combustion of coke that remains in the material on the grate after the volatile hydrocarbons have been removed by distillation in an earlier distillation zone.
