The invention is a two part composition useful for initiating cure of one or more polymerizable monomers which cure when exposed to free radicals comprising in one part an organoboraneamine complex and in a second part an isocyanate which is capable of decomplexing the organoborane complex wherein the ratio of amine nitrogen atoms to boron atoms is greater than 4. The operation of the switching units takes place in such a way that the at least one precharging resistor is used simultaneously for charging and discharging the DC voltage intermediate circuit. Thereby, an optimum seek position at which the lens offset is canceled can be set with no waste, resulting in an improvement in access time. This design creates a very compact unit due to the fact that the fuel tank, burner and cooking surface all fit in a vertical column thus requiring minimal space. A pulse width measurer may be configured to receive the output voltage of the charge pump and determine whether pulses forming the side-band signal have appropriate widths based on whether the output voltage is included in a desired reference voltage range. The server queues the supplemental files in an order dictated within the HTML code itself and serves the supplemental files in the order dictated in the queue regardless of the order of which the Web browser at the client-side requests the supplemental files.
