Self-generated

Mists Althougn charged mists are unable to cause ignition of flammable vapor by self-generated sparking, it is impoi tant that the mist not impinge upon an ungrounded conduc tor. 

Self-Generated Discharges Vapor-air mixtures can be ignited by sparks from highly charged liquids. It is said that such liquids cany their own match. Typical causes of such charging for poorly conductive (<50 pS/m) liquids include ... 

Since acceleration is the second derivative of displacement, a piezoelectric accelerometer sensor with an integrator becomes a velocity transducer. This arrangement is gradually superseding the self-generating mo ing-coil velocity sensor (where a coil of wire moves relative to a magnetic field). 

The gases are again dried and then further compressed to about 550 psi. Separation of hydrogen and methane take place in the demethanizer and in its preflash system. Three successive Golder preflash steps are used in this separation, with propylene as refrigerant, then ethylene, and finally a self-generated methane refrigerant at -200 F. 

Apart from considerations given to corrosion resistance and suitability for hazardous (classified) areas, the selection of electric motors for oil field applications is the same as the selection of electric motors for other industrial applications. One exception may be the selection of motors for areas where electric power is self-generated. Frequency and voltage variations may occasionally occur at such locations. For such locations, consideration should be given to specifying motors which are tolerant to at least 10% voltage variations and 5% frequency variations.

The conclusion that each inner-core spheron in a stable core should ligate its neighbors about itself in a way corresponding to local stability is a reasonable consequence of the self-generating character of the potential energy function for nucleons in nuclei (mutual interdependence of structure and potential energy function) and the short range of internucleonic forces. 

Effective mentors have a portfolio of models that they can draw upon to help mentees understand the issues they face. These models can be self-generated (i.e. the result of personal experience), drawn from elsewhere (e.g. models of company structure, interpersonal behaviours, strategic planning, career planning) or -...

Self-generated surfactants (produced from fossil fuels by a chem-ical/physical process) or natural surfactants (exiting in fossil fuels) are derived from the inherent organic acids and replaceable acidic protons which are present in crude oils or bitumens (e.g., mercaptans). Yen and Farmanian (2) isolated native petroleum fractions that form surfactants and contain hydrogen dispiacable components including one, two, three, or four of die following types ...
