Abstract: INTERFRAME CODING APPARATUS            Abstract In interframe coding apparatus in which an input signal is encoded by an interframe coder and its output code is written in a buffer memory, and is read out therefrom at a constant bit rate, a variable characteristics comb filter is provided at a stage preceding the interframe coder.  The period of the frequency characteristics of the comb filter is selected to be the frame period of the input signal. By a controller, the occupancy of the buffer memory is detected to control either one or both of the attenuation in the elimination band and high frequency cut-off characteristics of the comb filter detected value to prevent an overflow from the buffer memory.

Abstract: STEPPING MOTOR USING EXTENDED DRIVE PULSES    ABSTRACT         A stepping motor is driven with extended pulses producing an effective excitation intermediate to the single phase and the dual phase operations.  The unique drive cir-cuit creates a series of drive pulses for each motor phase so that each pulse slightly overlaps the drive pulse of the next adjacent phase.  Thus, since each previous phase is still providing torque while the current in the next phase is being built up, the torque characteristics are improved, and the extended pulses are terminated before the subsequent phase is energized so that excessive power consumption is avoided.  In closed loop systems, a fixed duration overlap provides the improved speed-torque char-acteristic at high speeds where the overlap is a large percentage of the drive pulse, while at lower speeds (such as when the motor is accelerating) where power consumption is greatest, the overlap is a smaller percentage of the drive pulse hence minimizing the increase in power consump-tion.  This type of operation maximizes slew speed while conserving power consumption at low speeds.  In open loop systems, using extended drive pulses increases the torque over that provided by single phase excitation, and the duration of the overlap may be adjusted so that large over-laps occur only where the torque needs are greatest (at times of acceleration, for example) while small overlap occur where torque requirements are low (during constant speed operation, for example), thus minimizing the total overall power consumption.

Abstract: ABSTRACT OF THE DISCLOSURE An absorbent is removed from an adsorbent by contact-ing the adsorbent with a near critical liquid which is a solvent for the adsorbate.  The near critical liquid containing the dis-solved adsorbate is then subjected to at least partial vaporiza-tion to form a vapor in which the adsorbate is substantially less soluble thereby making it possible to remove the adsorbate from the near critical liquid.  The vapor is then condensed to restore it to the near critical liquid state wherein it is a solvent for the adsorbate so that it may be reused.  The process is particular-ly suitable for adsorbent regeneration in the treating of waste-waters.

Abstract: METHOD AND APPARATUS FOR CONDITIONING MATERIAL UTILIZING     AIRFLOW CONTROL MEANS     ABSTRACT OF THE DISCLOSURE    A method and preferred apparatus for conditioning materials such as tobacco using an airflow distributor means.  A conveyor transports the material along a path, and means to control the conditioning of the material are located at selected locations. A source of gas produces a gas stream, and means are operatively associated with the source of gas to selectively condition the gas stream.  Flow straightening means having a structure such as a honeycomb panel are positioned upstream of the material being transported on the conveyor.  The gas stream source is positioned to direct the gas stream through the flow straightening means to spread the gas stream evenly across the conveyor surface for uniform conditioning of the transported material.  The con-ditioning may include heating and/or cooling the material, introducing moisture into the gas stream, adding chemicals into the gas stream, or selected combinations of these.

Abstract: 1950-58a ABSTRACT OF THE DISCLOSURE                 Latent images which are formed on dielectric receptor sheets during exposure to object-modulated primary and stray X-rays, while the sheets dwell in the interelectrode gap of an ionography imaging chamber, are developed in an electrophoretic unit which neutralizes the effect of stray radiation upon the receptor sheets so that the developed visible images are reproductions of those portions of latent images which are formed as a result to exposure to primary radiation.  The neutralizing involves ascertaining the intensity of stray radiation behind the imaging chamber by resorting to one or more dosimeters and one or more rasters or analogous devices which absorb stray radiation, and applying to the electrodes of the developing unit a reverse potential which is proportional to the intensity of stray radiation.  Alternatively, the intensity of stray radiation can be ascertained empirically and the reverse potential is selected by hand, depending on the density and thickness of the object.

Abstract: ABSTRACT OF THE DISCLOSURE           A receiver for a carrier that is swept in frequency in a predetermined manner over a bandwidth comprises frequency track-ing with continuous self-synchronization.  The frequency track-ing permits the carrier to be filtered by a narrowband filter.          The filtered carrier is then fed to a frequency discriminator to produce an error signal.  A highly-selective phase-locked loop synchronizes only to the desired component of the error signal in frequency and in phase.  The output of the phase-locked loop, after appropriate shaping, is the control signal for tracking synchronously the incoming wave.  The output data are obtained at detection after the narrowband filtering.

The agitator device comprises a "main beam" which extends axially of and in overlying relation to the upper outer peripheral surface of the cylinder cage.  A plurality of arcuate scraper fingers are mounted on and move with the "main beam" and extend in contiguous overlying relation to the outer periphery of the cylinder cage.  A carriage member secured to the agitator device is mounted for sliding movement on a pair of horizontal guide rails.  Reciprocating movement is imparted to the slidable carriage and to the agitator device by an endless drive chain which is driven at a constant speed and with a continuous motion.  The slidable carriage is connected to the drive chain through a drive link which is pivotally connected at its opposite ends to the drive chain and to the slidable carriage.  The pivotal connection of the drive link to the chain follows the path of movement of the chain, whereby to cause reciprocatory motion of the slidable carriage and of the agitator device.  As the agitator device reciprocates above the screen-like cylinder cage, the scraper fingers of the agitator device agitate and loosen any straw on the upper outer peripheral surface of the cylinder cage.
