Abstract
Abstract A transportation system is comprised of a first closed loop passenger and cargo transporter section with such section being ideally intended to operate at a substantially constant speed, and a second closed loop passenger transfer section with such section being intended to operate, generally between the first closed loop and a related stationary passenger platform, as to cyclically maintain a speed equivalent to the constant speed of the first closed loop, then decelerate until it is stationary with respect to the related stationary passenger platform and then accelerate until it is again at the speed of the first closed loop transporter section. Passengers and cargo may, during the time that the transfer section is stationary with respect to the passenger platform, transfer from the platform onto the then stationary transfer section (or if getting off of the system, transfer from the then stationary transfer section onto the platform). After the second closed loop transfer section has accelerated and attained the speed of the moving first closed loop transporter section, the passengers on the transfer section may, during the time that both sections are of the same speed, transfer from the transfer section onto the transporter section (or, if in the process of getting off of the system, transfer from the transporter section onto the transfer section). After the second closed loop transfer section has decelerated and again becomes stationary with respect to the stationary passenger platform, such passengers getting onto or getting off the system may again, as the case may be, transfer from the stationary platform onto the transfer section or transfer from the transfer section onto the platform. The above cycle of operation continues during operation of the overall transportation system.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
176 words
A method of transporting an entity to be transported from a first stationary station area to a second stationary station area, comprising the steps of transferring said entity from said first stationary station area to a second area defined by first means standing in stationary relationship to said first stationary station area, accelerating said first means until said first means attains a velocity substantially equivalent to the existing velocity of second means defining a third area contiguous to said second area, transferring said entity from said second area to said third area, transporting said entity on said third area at said existing velocity for a distance less than the distance between said first stationary station area and said second stationary area, transferring said entity from said third area while at said existing velocity to said second area, controllably decelerating said first means from said existing velocity until said first means attains a stationary relationship with respect to said second stationary station area, and transferring said entity from said second area to said second stationary station area.
Claim 2
Independent Claim
176 words
A method of transporting an entity to be transported from a first stationary station area to a second stationary station area, comprising the steps of transferring said entity from said first stationary station area to a second area defined by first means standing in stationary relationship to said first stationary station area, accelerating said first means until said first means attains a velocity substantially equivalent to the existing velocity of second means defining a third area contiguous to said second area, transferring said entity from said second area to said third area, transporting said entity on said third area at said existing velocity for a distance less than the distance between said first stationary station area and said second stationary area, transferring said entity from said third area while at said existing velocity to said second area, controllably decelerating said first means from said existing velocity until said first means attains a stationary relationship with respect to said second stationary station area, and transferring said entity from said second area to said second stationary station area.
Claim 3
Dependent Claim
53 words
A method of transporting an entity to be transported according to claim 1 and further comprising the step of positively preventing the transfer of any such entity from said first stationary station area to said second area whenever said first means is not standing in stationary relationship to said first stationary station area.
Claim 4
Dependent Claim
45 words
A method of transporting an entity to be transported according to claim 1 and further comprising the step of positively preventing the transfer of any such entity from said second area to said third area whenever said first means is not at said existing velocity.
Claim 5
Dependent Claim
80 words
A method of transporting an entity to be transported according to claim 1 and further comprising the steps of positively preventing the transfer of any such entity from said first stationary station area to said second area whenever said first means is not standing in stationary relationship to said first stationary station area, and positively preventing the transfer of any such entity from said second area to said third area whenever said first means is not at said existing velocity.
Claim 6
Dependent Claim
205 words
In a method of transportation coordination wherein entities are to be transported from one station to another, the improvements comprising the steps of supporting said entities on a primary carrier, supporting said entities on a secondary station, supporting said entities on a tertiary carrier, first imparting translation at substantially constant non-zero speed on said primary carrier with respect to said tertiary carrier, secondly imparting translation on said secondary carrier with respect to said primary carrier such that said secondary supporting means translates at the same speed as said primary carrier during a first phase and said secondary carrier translates at the same speed as said tertiary carrier during a second phase, conditioning said secondly imparted translation cyclically from accelerating from said second phase to said first phase and controllably decelerating from said first phase to said second phase, limiting the path of translation of said primary carrier to being fixed at a closed perimeter, maintaining said path and said primary carrier to being simultaneously substantially contiguous throughout their respective lengths, limiting the path of translation of said secondary carrier to being fixed to a closed perimeter, and maintaining said second mentioned path and said secondary carrier to being simultaneously substantially contiguous throughout their respective lengths.
Claim 7
Dependent Claim
205 words
In a method of transportation coordination wherein entities are to be transported from one station to another, the improvements comprising the steps of supporting said entities on a primary carrier, supporting said entities on a secondary station, supporting said entities on a tertiary carrier, first imparting translation at substantially constant non-zero speed on said primary carrier with respect to said tertiary carrier, secondly imparting translation on said secondary carrier with respect to said primary carrier such that said secondary supporting means translates at the same speed as said primary carrier during a first phase and said secondary carrier translates at the same speed as said tertiary carrier during a second phase, conditioning said secondly imparted translation cyclically from accelerating from said second phase to said first phase and controllably decelerating from said first phase to said second phase, limiting the path of translation of said primary carrier to being fixed at a closed perimeter, maintaining said path and said primary carrier to being simultaneously substantially contiguous throughout their respective lengths, limiting the path of translation of said secondary carrier to being fixed to a closed perimeter, and maintaining said second mentioned path and said secondary carrier to being simultaneously substantially contiguous throughout their respective lengths.
