Abstract: S P E C I F I C A T I O N     AN IMPROVED MULTI-ROW CROP HEADER     ABSTRACT OF THE DISCLOSURE A multi-row crop header for a forage harvester has a central rear discharge outlet, a transversely extending consolidating auger and a plurality of fore-and-aft extending crop dividers.  The crop dividers define forward crop passageways and rear crop passageways extending from the forward crop passageways.  At least some of the rear crop passageways are angled inwardly from front to rear, toward the longitudinal centerline of the header.  Disposed within each of the rear crop passageways is a set of butt-gripping chains that grip the butt-ends of the stalks and convey the same rearwardly toward the central discharge outlet.  As the butt-ends are conveyed inwardly toward the central discharge outlet, upper directing chains on the header direct the upper intermediate portions of the stalks inwardly toward the longitudinal centerline of the header and upper guide arms on the header direct upper more remote portions of the stalks inwardly toward the centerline of the header. The cooperation between the auger, the angled rear passageways, the lower butt-gripping chains, the upper directing chains and the upper directing guide arms tends to orient the crop stalks in a generally fore-and-aft direction as they reach the middle or central section of the auger where the stalks are fed rearwardly through the rear discharge outlet and thereby promotes butt-end feeding of the stalks which results in a more efficient harvesting operation.

Abstract: DATA-ENTRY/DATA-RETRIEVAL TERMINAL            ABSTRACT OF THE DISCLOSURE    A data collection terminal for displaying data and for transmitting to and receiving data from a central station has a keyboard and facility for peripheral devices for entering data.          A numeric readout is provided and may be used if desired.  Further, a grid of light emitting diodes (LED's) is provided.  A remov-able mask may be placed over the LED's so that each LED corres-ponds to a specified field of terminal operation, depending upon the particular use to which the terminal is put.  Function keys and a set of numeric keys are provided, the former for causing operations to be performed and the latter for entering numeric data.    The terminal is controlled by a microprocessor and associated circuits, particularly including a read-only memory (ROM) which is configured to control the microprocessor in a desired manner to provide the terminal with a specified con-figuration to perform a particular task or tasks.  Tutorial circuitry is provided for optionally displaying sequential prompting steps on the numeric readout and/or the LED grid to permit an operator of the terminal to follow the prompt-ing steps for proper entry of a desired transaction.    Circuit means are also provided for identifying data as to its peripheral device source or keyboard source as it is written into temporary storage in consecutive memory locations irrespective of the source, the data being reidentified as to its source when read out and transmitted to the central station.    The numeric readout in the preferred embodiment is a vacuum fluorescent display whose filament is activated by a DC potential.  To compensate for the progressive voltage drop along the DC filament, the characters are activated for varying lengths of time depending upon their position within the vacuum fluorescent display, providing apparent equal brightness to each character displayed.

Abstract: SEAT BELT RETRACTING AND WINDING DEVICE            ABSTRACT OF THE DISCLOSURE         A seat belt retracting and winding device is provided with a driving wheel rotatable in unison with a seat belt winding shaft, ratchet means consisting of a ratchet wheel and a catch, a cam disk and a catch holding disk adapted to maintain the catch in position in engagement with or disengagement from said ratchet wheel.  Strong and weak springs are encased within the ratchet wheel and the driving wheel, respectively, and are interconnectable in series to each other.  When the seat belt is paid out and fastened, the catch holding disk and the catch cooperate with each other to lock the ratchet wheel so that the strong spring is disconnected from the weak spring and consequently unpleasant restrain-ing force on a driver or occupant may be reduced or relaxed.  On the other hand when the seat belt is un-fastened, the rotation of the winding shaft in the opposite direction causes the cam disk and the catch holding disk to cooperate with each other so as to release said locked ratchet wheel for free rotation so that the strong spring is drivingly coupled to the weak spring and consequently the positive and complete retraction of the seat belt may be ensured.

Abstract: MEMORY SPARING ARRANGEMENT                         Abstract A digital data processing arrangement for pro-viding automatic substitution of a spare memory module for a malfunctioning portion of the system memory is disclosed.  The substitution takes place in a manner transparent to the software programs being run in the processing system.  The system memory is organized as a plurality of memory modules, each having an identical number of individually addressable words.  A particular module is enabled on receipt of an appropriate signal via a dedicated lead from the system processor unit, while a particular word within that module is specified by an address received via an address bus running to address decoder units at all modules.  When the error detection and identification routines of the system processor determine that a particular module is malfunc-tioning, a hardware register and accompanying comparison logic are arranged such that a spare module is accessed whenever the particular malfunctioning module is subse-quently addressed.  The approach does not diminish the available system memory address range after spare module substitution.  Additionally, no memory reconfiguration is required after spare module substitution except for loading of the spare module itself whenever program memory substitution is involved.

Abstract: A B S T R A C T           In heart monitoring systems for use with patients whose hearts may be stimulated by an artificial pacer and which system includes heart rate indicating means, there is provided circuitry for suppressing the recharge waveform portion of a pacer signal artifact in addition to suppression of the discharge pulse portion of the signal artifact, thereby to prevent inaccuracies in the heart rate indication arising from the pacer signal artifact.  In addition to suppressing the discharge pulse portion of a pacer signal artifact with conventional means, the invention recognizes that the recharge waveform of the pacer signal may cause a false impression or a QRS complex which actuates heart rate indicating means and provides novel circuitry for suppress-ing such recharge waveform.         Circuitry is provided for recognizing the occurrence of a pacer discharge pulse and for generating a suppression signal in timed relation thereto which, when arithmetically added to the recharge waveform portion, acts to cancel or suppress such recharge portion. The suppression signal is of inverse polarity to the recharge waveform portion and is generated by sampling the pacer signal artifact substantially at the beginning of the recharge waveform to determine the magnitude thereof.  In a preferred embodiment, a pacer signal artifact and the termination of the discharge pulse portion thereof is identified by novel rate and duration measuring circuitry.

Abstract: ABSTRACT OF THE DISCLOSURE         A coilable rule is provided with a combination blade lock and shock absorber mechanism to lock its measuring blade in an extended position and absorb the shock of impact upon retraction of the blade.  A lever is attached to the rule housing by a slidable pivot con-nection which allows the lever to be manually pivoted into and out of engagement with the measuring blade and also permits longitudinal movement of the lever relative to the housing.  The lever is normally biased against the measuring blade by a bias spring to lock the blade in any extended position.  When the blade is released and retracted under the action of its recoil spring, a blade pull-out hook contacts and moves the lever longitudinally against the bias spring to slide the lever relative to the housing and absorb the shock of impact.
