Abstract: An electrochemical device includes a lithium anode having a red poly(benzonitrile) coating covering at least a portion of the anode; a separator and an air cathode comprising reduced graphene oxide over gas diffusion layer; and an electrolyte comprising an ether solvent, benzonitrile, and a lithium salt.

Abstract: The present invention provides, in part, methods and processes for the production of lithium superoxide (LiO2) which is free of other lithium-oxygen compounds, as well as compositions and electrochemical cells comprising lithium superoxide (e.g., lithium superoxide that is free of other lithium-oxygen compounds).

Abstract: A method, apparatus or computer program implements an overload prevention approach involving monitoring a speed of a motor; detecting an overload condition of the motor based on the monitored speed; and controlling an operation of the motor according to the detected overload condition.

Abstract: An improvement to a chart recorder where the chart paper is driven by a motor responsive to pulses counted by a microprocessor makes it possible for the operator to set the pen to a major grid line on the chart at any time after initialization by merely pressing a key. Using a programmed counter the microprocessor keeps track constantly of how many counts the paper has advanced and how far it is to the next major grid line. Upon key command the microprocessor through a software routine advances the paper to the next major grid line. If desired, the routine can also be programmed to raise the pen during advance and lower it at the major grid line.
