A pump method, said method operating in conjunction with a pump system comprising:
- (a) a material hopper (MHOP);
- (b) a trapezoidal-shaped spectacle plate (TSSP);
- (c) a hydraulic pump;
- (d) a trapezoidal-shaped cutting ring (TSCR);
- and
- (e) an ejection port;
- wherein:
- said TSSP comprises a first trapezoidal inlet port (FTIP) and a second trapezoidal inlet port (STIP);
- said TSSP is attached to said MHOP and configured to supply material from said MHOP to said hydraulic pump through said FTIP and said STIP;
- said hydraulic pump comprises a first hydraulic pump ram (FHPR) and a second hydraulic pump ram (SHPR);
- said FHPR is configured to accept material via said FTIP;
- said SHPR 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 hydraulic pump is configured to eject material from said FHPR into said TROP when said TROP is positioned to cover said FTIP;
- said hydraulic pump is configured to inject material from said MHOP into said SHPR when said TROP is positioned to cover said FTIP;
- said hydraulic pump is configured to eject material from said SHPR into said TROP when said TROP is positioned to cover said STIP;
- and
- said hydraulic pump is configured to inject material from said MHOP into said FHPR when said TROP is positioned to cover said STIP;
- said TSCR comprises a transfer cavity having a geometric perimeter shape comprising an annular sector that approximates an isosceles trapezoid;
- said TSSP comprises a transfer cavity having a geometric perimeter shape comprising an annular sector that approximates 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 FHPR and said SHPR (4101);
- (2) Ejecting material using said FHPR and said SHPR into said TROP (4102);
- (3) Shifting said TROP over said FHPR and sealing off said SHPR (4103);
- (4) Ejecting material into said TROP using said FHPR (4104);
- (5) Shifting said TROP over said FHPR and opening said SHPR to said MHOP (4105);
- (6) Ejecting material into said TROP using said FHPR and injecting material from said MHOP using said SHPR (4106);
- (7) Shifting said TROP over said FHPR and opening said SHPR to said MHOP (4207);
- (8) Ejecting material into said TROP using said FHPR and injecting material from said MHOP using said SHPR (4208);
- (9) Shifting said TROP over said FHPR and sealing off said SHPR (4209);
- (10) Ejecting material into said TROP using said FHPR and stopping said SHPR when fully loaded (4210);
- (11) Centering said TROP over said TSSP to open said TROP to said FHPR and said SHPR (4211);
- (12) Ejecting material into said TROP using said FHPR and said SHPR (4212);
- (13) Shifting said TROP over said SHPR and sealing off said FHPR (4313);
- (14) Ejecting material into said TROP using said SHPR and stopping said FHPR when fully ejected (4314);
- (15) Shifting said TROP over said SHPR and opening said FHPR to said MHOP (4315);
- (16) Ejecting material into said TROP using said SHPR and injecting material from said MHOP using said FHPR (4316);
- (17) Shifting said TROP over said SHPR and sealing off said FHPR (4317);
- (18) Ejecting material into said TROP using said SHPR and stopping said FHPR when fully loaded (4318);
- and
- (19) Proceeding to step (1) to repeat material pumping operations.
