To reduce clutter in circuit diagreuns, it is common to omit the power terminals, for example, as shown in Figure 6.2. The presence of power terminals is nevertheless assLuned. 

An ally silane is a further powerful terminating group. The initiation, either with Lewis or protic acids under mild conditions, generates the fraw-hydrindanc system 4 in high yields. The relative stereochemistry of the side chain is found to be unselective".

Modem real time instmmental methods permit analyses of unstable transient species and the free-radical intermediates as well. These methods have gready expanded the scope and power of VPO studies, but important basic questions remain unresolved. Another complication is the role of surface. Peroxide decompositions and radical termination reactions can occur on a surface so that, depending on circumstances, surfaces can have either an inhibiting or accelerating effect. Each surface has varying amounts of adventitious contaminants and also accumulates deposits during reaction. Thus no two surfaces are exactly alike and each changes with time. 

In practice, elimination of axial current flow requires relatively fine segmentation, eg, 1—2 cm, between electrodes, which means that a utihty-sized generator contains several hundred electrode pairs. Thus, one of the costs paid for the increased performance is the larger number of components and increased mechanical complexity compared to the two-terrninal Faraday generator. Another cost is incurred by the increased complexity of power collection, in that outputs from several hundred terminals at different potentials must be consoHdated into one set of terminals, either at an inverter or at the power grid. 

Another configuration having power collection from only two terminals is the Hall generator shown in Figure 5d. In this configuration, opposing electrode pairs are connected, and the current flow for power extraction is axial. E = 0, and... 

For current consoHdation, the basic circuits, used at each of the multiple power take-off points, are stacked into a Christmas tree topology to form a single power take-off terminal pair. Scale-up of these devices to commercial sizes is not expected to be a problem, as standard electrical components are available for all sizes considered. A different type of consoHdation scheme developed (117), uses dc to ac converters to connect the individual electrodes to the consoHdation point. The current from each electrode can be individually controUed by the converter, which can either absorb energy from or deHver energy to the path between the electrode and the consoHdation point. This scheme offers the potential capabiHty of controlling the current level of each electrode pair. 

In the second method, the pump and the motor are coupled direcdy, and either power (in kilowatts) or the current, I, and voltage, U, ate measured at the motor terminals. To determine the power actually transmitted into a pump, the motor power factor (PF) and efficiency (Eff ) must be known. These values ate usually taken from the motor manufacturer s caUbration curves (17). 

Emulsion Polymerization. Emulsion polymerization takes place in a soap micelle where a small amount of monomer dissolves in the micelle. The initiator is water-soluble. Polymerization takes place when the radical enters the monomer-swollen micelle (91,92). Additional monomer is supphed by diffusion through the water phase. Termination takes place in the growing micelle by the usual radical-radical interactions. A theory for tme emulsion polymerization postulates that the rate is proportional to the number of particles [N. N depends on the 0.6 power of the soap concentration [S] and the 0.4 power of initiator concentration [i] the average number of radicals per particle is 0.5 (93).
