Abstract: VARIABLE SPEED REVERSIBLE DRIVE   FOR A HARVESTING APPARATUS                 Abstract of the Disclosure An agricultural crop harvester's feeding and gathering units are driven by a power source on the harvester through a sheave assembly journaled on a countershaft mounted towards the rear of the feeding unit.  Power is thence transmitted by a variable ratio V-belt drive to a speed reducing and direction reversing planetary gear unit mounted forwardly on the feeding unit and finally to the gathering and feeding mechanisms by drives of conventional design.  In the variable ratio V-belt drive, the effective diameter of a split sheave output portion of the countershaft sheave assembly is selectively adjusted hydrau-lically while, in inverse response, the effective diameter of a spring loaded variable driven split sheave, integral with the planetary gear unit, adjusts automatically.  In addition, the driven sheave is provided with a coaxial cam arrangement respon-sive to changes in torque transmitted so that its effective diameter also adjusts automatically to provide appropriate belt tension.  Interposing a speed reducing planetary gear unit in the drive system following the V-belt drive makes possible the use of comparatively higher belt speeds and smaller sheave diameters and facilitates provision of a selectively reversible drive to the gathering and feeding units.  The reversed speed of rotation of the output of the planetary unit is substantially lower than its forward speed.

Abstract: ABSTRACT OF THE DISCLOSURE           A blow molded collapsible solution container having improved characteristics of collapsibility as shown.  The container defines a body portion having an integral neck portion and a generally elongated, re-latively stiff shoulder portion at one end thereof, and is sealed at its opposite end.  The body portion defines, in its original, unstressed configuration, a generally oval transverse cross section adjacent the shoulder portion, said cross section tapering progres-sively to a flat configuration at said end of the container opposite to said one end  to  facilitate a uniform, flat collapse of the container progressively from said opposite end towards said one end as the contents thereof are withdrawn through said neck portion when the container is disposed in neck-downward position.          The container also defines gusset portions in the body portion adjacent the shoulder portion.  The gusset portions include lines of flexing weakness to facilitate collapse of the container adjacent the shoulder portion as the contents thereof are withdrawn.  The gusset portions de-fine three sides in triangular relationship, one of said sides being adjacent and parallel to a shoulder tip at the ends of the major axis of said elongated shoulder portion, and the other two sides extending from said one side of the gusset portion toward each other.  The container is free of longitudinally oriented lines of flexing weakness adjacent the shoulder portion.

Abstract: ABSTRACT OF THE DISCLOSURE        A system and method for accessing remote locations and transferring data to and from the accessed location, par-ticularly where the data is control data and billing information regarding programs actually viewed by a subscriber of a sub-scription television system, where access is over non-dedicated telephone lines.  In the disclosed system, a scrambled tele-vision program signal containing a block of television program material and a program identification code unique to the block of program material is transmitted in the vertical retrace interval at a predetermined carrier frequency.  The transmitted program signal is selectively received at a subscriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material.  The program identification code in the program signal received at the subscriber station is detected and stored for subsequent transmission as an electrical signal in response to the subscriber acceptance action.  The program identification code stored at the subscriber station is selectively accessed from a remove location over non-dedicated telephone lines on other than a real time basis (e.g., a periodic basis) to thereby pro-vide billing information at the remote location as to programs actually viewed by the subscriber.  The subscriber can thus be billed on some desired periodic basis for programs actually viewed.  Access is provided by selectively conditioning the remote terminal to generate dialing signals and to thereby provide selective connection of the accumulator to the telephone lines from the remote subscriber station.  A preconditioning circuit such as timing means or a broadcast signal decoder at the sub-scriber's station conditions the remote terminal to effect a connection by telephone to the central station during a time of the day when the telephone there is not likely to be used for normal telephone calls.
