Abstract: ABSTRACT OF THE DISCLOSURE A motorcycle frame and suspension system employing a backbone frame member extending rearwardly over an engine and then downwardly where it is associated with an inverted U-shaped center frame.  Two pivot mechanisms for a rear fork are positioned in line with the ends of the inverted U-shape center frame and a cushion member is located therebetween.  The cushion member is linked at its first end with the middle of the center frame and at its second end to a linkage mechanism fixed to move with the upward pivotal motion of the rear fork.  The mechanism is so proportioned as to provide an increasing rate of upward motion to the cushion member as the rear fork moves upwardly.  The two pivot mechanisms are not identical, one allowing axial sliding movement and the other not allowing such movement.

Abstract: ABSTRACT      A process is described for the separation of carbon dioxide and sulfide gases from oil shale re-torting off-gases, coal gasification off-gases, oxygen fireflooding off-gases or carbon dioxide miscible flood enhanced oil recovery off-gases for recycle to a retort, gasifier, petroleum reservoir or to further sulfide processing prior to export.  The process separates the off-gases into an essentially sulfur-free light BTU fuel gas, a heavy hydrocarbon stream and a carbon dioxide acid gas stream wherein the off-gas is com-pressed if necessary and cooled to separate the various streams.  The carbon dioxide acid gas stream is expanded in an auto-refrigeration step to provide the necessary process refrigeration.  In the oil shale retort and coal gasification applications the sulfur constituents are sorbed on spent oil shale particles or coal ash.

Abstract: SOLID-STATE ELECTRICAL-POWER DEMAND        REGISTER AND METHOD            ABSTRACT OF THE DISCLOSURE          A solid-state demand register is described for determining the maximum electrical-power demand made on an electric utility by a load.  The register, which employs a microprocessor,  provides noncumulative, cumulative, and continuous-cumulative electrical-power  demand  measurement  capabilities.    The  microprocessor, operating under a control program stored in a read-only memory, employs  computing  constants  and generates computed  results. A nonvolatile  read/write  memory,   which   stores   the  computing constants  and  computing  results,  is  of  the  type  that retains stored data even when deenergized.  These constants and results can be visually displayed by an optoelectronic display.   Error detection and correction of data are performed by the programmed microprocessor  by  means of  an  eight-bit  Hamming  code.   The register further includes  pulse generators for generating pulses indicative  of  the  electrical-power  demand  and  the  end  of  a demand-monitoring  time  interval,  and  includes a controller  for inhibiting  the  optoelectronic  display  when  the  ambient  light adjacent the controller falls below a preselected threshold level.

Abstract: LOOP TRANSMISSION SYSTEM AND METHOD OF CONTROLLING THE LOOP-BACK CONDITION THEREOF                 ABSTRACT OF THE DISCLOSURE      A loop transmission system and a method of con-trolling the loop-back condition thereof.  The loop transmission system comprises a plurality of node stations, a supervisory station, and two duplicate loop transmission lines which transmit signals in opposite directions.  In the loop transmission system, the supervisory station first sends out loop-back commands via both of the duplicate loop transmission lines when faults are detected on both of the duplicate loop transmission lines at the same time.  Each of the node stations establishes a loop-back path while retaining a connection path to a succeeding node station upon the receipt of a loop-back command.  The loop-back path is released only in the node stations which receive signals normally from both of the duplicate loop transmission lines when the supervisory station sends release commands to the node stations after sending the loopback commands.
