Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
       [0001]    It is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. 
         [0002]    This rotational torque and power transfer system&#39;s basic operation is that during a speed transfer/change of the Prime Mover (Engine), the Generator remains running at a constant speed (1800 rpm/60 hz, or 1500 rpm/50 hz) while the Prime Mover reduces its speed from 1800 RPM to 1200 RPM (in order to optimize engine operation and reduce wear, emissions, and fuel consumption). A major operational goal is to keep producing power (at 6 0  hertz and synchronized—if running in parallel), during the engine speed transfer without any electrical disruption. 
         [0003]    Note that the two (2) Flux Drive ASDs [‘ASD’=Adjustable Speed Drive] (as shown) will allow the Prime Mover (Engine) speed to change during the transfer from 1800 rpm to 1200 rpm, while keeping the Generator rotating at 1800 rpm and producing quality power. By using the Flux Drive ASDs, no components will wear out due to transient speeds generated during the speed changes of the engine and this drive system also has a very high efficiencies since full and reduced power operation of the Flux Drive ASDs will be at 98% efficiency (2% slip, or possibly even less at full engagement—lockup). 
         [0004]    As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the limited claims herein be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention. 
         [0005]    For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0011]    With reference now to the drawings,  FIGS. 1 through 4 , the preferred embodiment of the invention embodying the principles and concepts of the present invention. 
         [0012]    How this rotational torque and power system transfer works— 
         [0013]    1800 RPM Operation: (See Attached Drawing: 1800 RPM Prime Mover to 1800 RPM Generator)— FIG. 1  (Off-set, Belt Driven: Prime Mover-Generator arrangement); 
         [0014]    An in-line Flux Drive ASD ( 100 ) (with Automatic Actuator A1-18 engaged) will allow the Prime Mover ( 101 ) to drive the Generator ( 102 ) via a 1:1 belt drive ( 103 ) ratio (at 1800 rpm) to the non drive-end (NDE) of the Generator ( 102 ), off-set mounted next to a drive line/shaft ( 104 ) running in-line with the Prime Mover ( 101 ). This drive shaft ( 104 ) has two (2) pedestal bearings ( 105 ) for support, and a pulley/sheave ( 103 ) at its end driving a matching pulley/sheave ( 103 ) mounted on the Generator ( 102 ) with a drive (Ratio=1:1). The generator ( 102 ) mounted Flux Drive ASD ( 106 ) (with Automatic Actuator A2-18) is disengaged (with Automatic Actuator A2-18) during this mode of operation. (This condition=full speed/power operation) 
         [0015]    1800 RPM Operation: (See Attached Drawing: 1800 RPM Prime Mover to 1800 RPM Generator)— FIG. 3  (In-Line, Direct Driven: Prime Mover-Generator arragnement); 
         [0016]    An in-line Flux Drive ASD ( 300 ) (with Automatic Actuator A1-18 engaged) will allow the Prime Mover ( 101 ) to drive the Generator ( 102 ) direct driven (at 1800 rpm) to the drive-end (DE) of the Generator ( 102 ). The Auxiliary Shafting ( 301 ), supported by four bearings ( 302 ) is disengaged by Flux Drive ASD ( 303 ) (with Automatic Actuator A2-18) during this mode of operation. (This condition=full speed/power operation) 
         [0017]    1200 RPM Operation: (See Attached Drawing: 1200 RPM Prime Mover to 1800 RPM Generator)— FIG. 2  (Off-set, Belt Driven: Prime Mover-Generator arrangement); 
         [0018]    The generator ( 102 ) mounted Flux Drive ASD ( 106 ) (with Automatic Actuator A2-12) will allow the Prime Mover ( 101 ) to slow down to 1200 rpm (while keeping the Generator ( 102 ) speed at 1800 rpm). This is accomplished by the secondary, Flux Drive ASD ( 106 ) (with Automatic Actuator A2-12) engaging to speed up the second drive pulley/sheave combo ( 200 ) at the Drive End (DE) Generator ( 102 ). This 2nd Flux Drive ASD ( 106 ) is engaged during this speed transient (1800 to 1200 rpm of the Engine), thereby keeping the Generator ( 102 ) running at 1800 rpm/60 hertz. The primary (in-line) drive shaft Flux Drive ASD ( 100 ) (with Automatic Actuator A1-12) is dis-engaged during this speed transfer transient of the Prime Mover ( 101 ). 
         [0019]    Automatic ‘computer programmed’ electronic linear actuators (A1-12 and A2-12) will take a control signal that the engine speed control system will provide during the speed change of the Prime Mover ( 101 ) 
         [0020]    The end result is that the Generator ( 102 ) remains running at constant speed during the Prime Mover ( 101 ) speed reduction to 1200 rpm (and also during the prime mover speed up to 1800 rpm). 
         [0021]    Note: 1200:1800 rpm (1.5 speed up ratio—1200 rpm to 1800 rpm) on the secondary drive pulley/sheave ( 200 ) of the Flux Drive ASD ( 106 ). 
         [0022]    1200 RPM Operation: (See Attached Drawing: 1200 RPM Prime Mover to 1800 RPM Generator)— FIG. 4  (In-Line, Direct Driven: Prime Mover-Generator arrangement); 
         [0023]    The Auxiliary Shaft ( 301 ) mounted with Flux Drive ASD ( 303 ) (with Automatic Actuator A2-12) will allow the Prime Mover ( 101 ) to slow down to 1200 rpm (while keeping the Generator ( 102 ) speed at 1800 rpm). This is accomplished by the secondary, Flux Drive ASD ( 303 ) (with Automatic Actuator A2-12), mounted on the off-set Auxiliary shafting ( 301 ), fitted with four bearings ( 302 ), engaging to speed up the second drive pulley/sheave combo ( 400 ) at the Drive End (DE) of the Auxiliary Shafting ( 301 ) to 1800 RPM. A matching pulley/sheave ( 401 ) mounted on the generator-end of the Auxiliary Drive shaft ( 301 ), drives the Generator ( 102 ) with an equal drive ratio (Ratio=1:1). This 2nd Flux Drive ASD ( 303 ) is engaged during this speed transient (1800 to 1200 rpm of the prime mover), thereby keeping the Generator ( 102 ) running at 1800 rpm/60 hertz. The primary (in-line) drive shaft Flux Drive ASD ( 300 ) (with Automatic Actuator A1-12) is dis-engaged during this speed transfer transient of the Prime Mover ( 101 ). Automatic ‘computer programmed’ electronic linear actuators (A1-12 and A2-12) will take a control signal that the engine speed control system will provide during the speed change of the Prime Mover ( 101 ). 
         [0024]    The end result is that the Generator ( 102 ) remains running at constant speed during the Prime Mover ( 101 ) speed reduction to 1200 rpm (and also during the prime mover speed up to 1800 rpm). 
         [0025]    Note: 1200:1800 rpm (1.5 speed up ratio—1200 rpm to 1800 rpm) on the secondary 
         [0026]    Auxiliary shaft ( 301 ) pulley/sheave drive ( 400 ) of the Flux Drive ASD ( 303 ). 
         [0027]    It is therefore contemplated that the instant disclosure will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention. 
         [0028]    In so far as the description above and the accompanying drawings disclose any additional subject matter that is not within the scope of the claims below, the inventions are not dedicated to the public and the right to file one or more applications to claim such additional inventions is reserved. 
         [0029]    While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention.
