- said STDS and said SPCP are mechanically coupled together with a second driveshaft engagement key (SDEK);
- said FTDS comprises a first automatic reversing channel thread (FRCT) having first right-handed channel (FRHC) and first left-handed channel (FLHC);
- said STDS comprises a second automatic reversing channel thread (SRCT) having second right-handed channel (SRHC) and second left-handed channel (SLHC);
- said FDEK is configured to ride within said FRHC and said FLHC;
- said SDEK is configured to ride within said SRHC and said SLHC;
- said FMPR is configured to accept material via said FTIP;
- said SMPR is configured to accept material via said STIP;
- said TSCR comprises a trapezoidal receiver output port (TROP) configured to alternately traverse between positions that cover said FTIP and said STIP;
- said TROP is configured to completely cover said FTIP and said STIP during said alternating traversal between said positions that cover said FTIP and said STIP;
- said TROP is configured to direct material from said FTIP and said STIP to said ejection port;
- said mechanical pump is configured to eject material from said FMPR into said TROP when said TROP is positioned to cover said FTIP;
- said mechanical pump is configured to inject material from said MHOP into said SMPR when said TROP is positioned to cover said FTIP;
- said mechanical pump is configured to eject material from said SMPR into said TROP when said TROP is positioned to cover said STIP;
- and
- said mechanical pump is configured to inject material from said MHOP into said FMPR when said TROP is positioned to cover said STIP;
- said TSCR comprises a transfer cavity having a geometric perimeter shape comprising an annular sector having the shape of an isosceles trapezoid;
- said TSSP comprises a transfer cavity having a geometric perimeter shape comprising an annular sector having the shape of an isosceles trapezoid;
- and
- said TSCR geometric perimeter shape and said TSSP geometric perimeter shape are not identical;
- wherein said method comprises the steps of:
- (1) Centering said TROP over said TSSP to open said TROP to said FMPR and said SMPR;
- (2) Ejecting material using said FMPR and said SMPR into said TROP;
- (3) Shifting said TROP over said FMPR and sealing off said SMPR;
- (4) Ejecting material into said TROP using said FMPR;
- (5) Shifting said TROP over said FMPR and opening said SMPR to said MHOP;
- (6) Ejecting material into said TROP using said FMPR and injecting material from said MHOP using said SMPR;
- (7) Shifting said TROP over said FMPR and opening said SMPR to said MHOP;
- (8) Ejecting material into said TROP using said FMPR and injecting material from said MHOP using said SMPR;
- (9) Shifting said TROP over said FMPR and sealing off said SMPR;
- (10) Ejecting material into said TROP using said FMPR and stopping said SMPR when fully loaded;
- (11) Centering said TROP over said TSSP to open said TROP to said FMPR and said SMPR;
- (12) Ejecting material into said TROP using said FMPR and said SMPR;
- (13) Shifting said TROP over said SMPR and sealing off said FMPR;
- (14) Ejecting material into said TROP using said SMPR and stopping said FMPR when fully ejected;
- (15) Shifting said TROP over said SMPR and opening said FMPR to said MHOP;
- (16) Ejecting material into said TROP using said SMPR and injecting material from said MHOP using said FMPR;
- (17) Shifting said TROP over said SMPR and sealing off said FMPR;
- (18) Ejecting material into said TROP using said SMPR and stopping said FMPR when fully loaded;
- and
- (19) Proceeding to step (1) to repeat material pumping operations.
