The transformer assembly is coupled between a power supply and a pulse delivery circuit of the implantable cardiac stimulation device for charging a pair of defibrillation capacitors for delivering defibrillation pulses. Pipe reactor processes of the present invention have a multitude of advantages over prior art processes including improved heat transfer, volume control, agitation and disengagement functions. In the head elevation guiding member, the head assembly is given a biasing load in a radial direction of the lead screw. There are low battery power read-outs and automatic shutoffs. The fluid applicator is formed as a fluid transfer brush that wicks irrigation fluid from the fluid holder to the grinding bit. The de-shuffled order is different from the shuffled order.
