Abstract: Abstract of the Disclosure A method for separation of seeds, in which the seeds are incubated in a suitable environment and then dried to produce a pronounced difference in moisture content between filled-dead seeds and filled-viable seeds. These two seed fractions are then separated from each other by utilizing the moisture content difference.    The seed fractions may e.g. be separated from each other by placing seeds in a liquid density of which is somewhat lower than the density of viable seeds but higher than the density of filled-dead seed. In such a case the filled-dead seeds will float up whereas the viable seeds sink.

Abstract: ABSTRACT           A direct modulation FM data receiver comprising a mixer (14) having a first input for receiving a directly modulated FM signal (fc ? .DELTA.f), where .DELTA.f is the deviation and fc the carrier, and a second input for a local oscil-lator (20) signal (fL) having a frequency within the signal channel but offset from the input signal carrier (fc) by an amount (.delta.f).  Demodulating means (22 to 30) distinguish between the signalling tones (.DELTA.f + .delta.f) and (.DELTA.f - .delta. f) and derive a data output signal therefrom.  The implemen-tation of the demodulating means depends upon the demodu-lation strategy.  However for a strategy based on compar-ing the energies in the two signalling tones then this can be done by connecting the output of a mixer (14) to two bandpass filters (22, 24) having centre frequencies .DELTA.f + .delta.f and .DELTA.f - .delta. f.  The outputs therefrom are amplitude or envelope detected in detectors (26, 28) and applied to a comparator (30) from which the data output signal is derived.  Such a direct modulation FM receiver may be fabricated as an integrated circuit and is suitable for use in a paging receiver.

Abstract: A B S T R A C T      Inadvertent actuation of a rotating jaw trap is eliminated by limiting the rotation of spring-loaded jaw actuators in the trap set position.  The position-limited actuators prevent opening of the jaws beyond the set position if one of the Jaws is stepped upon by an animal which would otherwise release the trap-setting dog member from the trap trigger pan.  With this elimination of slack in the set Jaws, the trap is only sprung when the trigger pan is stepped upon.  In the preferred embodiment, the limitation of rotation by the actuators is effected by upturned flange members from the trap frame or frame-holding bracket,  The flange members may be apertured to receive pivot rods for the actuator members.

Abstract: ABSTRACT OF THE DISCLOSURE      An  image  input  terminal  (IIT)  with  automatic document handler for feeding documents to be scanned into registered position on the IIT platen.  The IIT includes a pair of multi-element scanning arrays with cooperating scan lamp and optics on a movable carriage disposed in scanning relationship with the platen.  Analog image signals gener-ated by the scanning arrays are initially processed in separate channels and then combined into a serial stream. The  stream of  analog  image  signals  may  optionally  be thresholded  or  screened  to provide  binary  level  image signals or converted to multi-bit gray scale.          A  control   system   including   microprocessor provides  timing  and  control  signals  for  synchronizing operation of the scanning carriage, document handler, and image signal reading and processing together with elec-tronic crossover between arrays to avoid loss of data, automatic signal gain control, and deletion of bad image signals or pixels.          A  defocused  calibration  strip  is  scanned  to provide  shading  signals  for  calibrating  the  individual scanning elements of the arrays, the shading signals being processed in successive blocks each of which comprises a preset number of shading signals.   Following processing, the shading  signals are  stored  in memory  and  accessed during normal scanning.  The shading signals are employed in all operational modes to compensate the image signals produced by the IIT for deficiencies in the scanning com-ponents.

Abstract: COUPLING FOR DRIVE SHAFT AND   SERVO-MOTOR DRIVEN SHAFT             ABSTRACT OF DISCLOSURE      A  mechanical  coupling  for  a  power  steering system and the like having a driven shaft reversibly rotated  by  a  servo-motor  in  response  to  either clockwise or counter-clockwise rotation of a drive shaft,  with the  coupling normally  connecting the motor to the driven shaft.   In the event of any failure  of  the motor to rotate the  driven shaft synchronously with the drive shaft, as for example, due to an electrical power failure, rotation of the drive shaft causes the coupling to disconnect the motor  from  the  driven  shaft  in  the  direction opposite to the torque applied by the drive shaft and  simultaneously  mechanically  couple  the drive shaft to the driven shaft for direct drive.  During that time,  the coupling continues to connect the motor to the driven shaft in the direction of shaft rotation.  Hence, the direct drive may be assisted by  any  remaining  motor  torque,  that  is,  any available torque which is below the level needed to achieve synchronous motion and which is applied in the direction of rotation.  But any motor torque or drag  applied  in  a  direction  opposite  to  the direction  of  rotation  is  disconnected  from  the driven shaft.
