Abstract: ABSTRACT OF THE DISCLOSURE         In a quadrature amplitude modulator, two binary, syn-chronous data signals representing four possible phase states of a carrier signal are sampled and respectively fed into two shift registers comprising part of a finite impulse response lowpass filter.  The samples in each corresponding pair of stages in the shift registers are multiplexed at twice the carrier frequency. Each multiplexer output is then added modulo-two to a binary signal at the carrier frequency using exclusise-OR gates.  The gate outputs are weighted in a desired fashion and summed and converted to an analog signal which exhibits a preferred spectral shape.  This approach enables the quadrature amplitude modulation function to be included within the structure of the finite impulse response lowpass filter.  The binary synchronous nature of the input data enables the structure of the filter to be sim-plified and the number of multiplexers and modulo-two adders to be reduced to a number equal to the number of bits stored from the input sequences.  An extension of this basic concept includes higher levels of encoding, specifically the case of sixteen or more possible phase and amplitude states of a carrier signal. The particular method for weighting and summing the multiplexed and modulated signals may utilize digital logic combined with resistors, switched capacitors, or a stored program combined with a digital-to-analog converter, and is suitable for integrated circuit fabrication.

Abstract: Abstract of the Disclosure A fastener for anchoring in a bore in a bone has a screw extending along an axis and having a substantially cylindrical outer surface formed with a helical screwthread.  The screw has at the screwthread a thread diameter and between the turns of the thread at the surface a root diameter smaller than the thread diameter.  An  anchor sleeve normally fitted in the bore and of an outside diameter corresponding generally to the diameter of the bore has an outer end formed with a laterally projecting rim normally lying against the bone around the bore, an outer end portion of an inside diameter greater than the root diameter but smaller than the thread diameter, and an inner end portion of an inside diameter smaller than the root diameter.  Thus when the screw is threaded into the sleeve its thread cuts into the outer portion without substantially deforming and spreading same and into the inner portion with substantial outward deformation and spreading of same.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of determining the stiffness and con-dition of a wooden body.  The method consists of ini-tiating the natural vibration of the body in a band of frequencies that cover at least two of the first five resonant modes of vibration.  An electrical response equivalent to the vibration motion of the body is generated and the electrical response is converted to a digital signal.  The resonant frequency of the body is calculated by analysing the digital signal.  By comparing the results with the results obtained using a mathemati-cal model the stiffness and condition of the body is determined.

Abstract: ABSTRACT OF THE DISCLOSURE         In a bandwidth compressed transmission system in which a frequency band of a television signal of 2:1 interlace system is compressed, on an encoder side, by interfield offset subsampling at a first sampling frequency corresponding to a substantially upper limit frequency of the television signal and, after an output signal thus subsampled is applied to a LPF for passing a signal component having an aliased portion resulting from the interfield offset subsampling and having a cut-off frequency substantially equal to one half of the first sampling frequency, by interframe offset subsampling at a second sampling frequency lower than the first sampling frequency and higher than one half of the first sampling, so that a multiplexed subsampled transmission signal which does not include an aliased portion of reverse phase results from the interframe offset subsampling.  When decoding, interframe interpolation processing of a multiplexed subsampled transmission signal is performed to obtain a signal for a still picture portion, while intrafield interpolation processing of the same transmission signal is performed to obtain a signal for a motion picture portion.  An interframe difference of the transmission signal is detected to obtain a motion detection signal.  The signals for still and motion picture are linearly mixed in accordance with the motion detection signal.  Motion can be detected completely by utilizing an interframe difference.  An arrangement of a receiver can be made simple and improves picture quality.

In a first embodiment, an endless chain having pockets for receiving individual seeds from a supply hopper affixed to predetermined lengths of the chain is driven by a sprocket wheel which is, in turn, belt-coupled to a ground-engaging towed wheel of the vehicle. The chain is longitudinally aligned rearward of a disk-like colter which digs the trench into which the seeds ultimately fall and the trench is then closed as the vehicle's frame supporting wheels pass by the trench. Means are provided for elevating the colter, the chain-driving wheel and the supply hoppers when, at the end of a planting row and when moving to or from the planting site. In an alternative embodiment, an endless chain having pockets for receiving individual seeds from a supply hopper, affixed to predetermined lengths of the chain, is driven by a sprocket wheel which is, in turn, miter gear-coupled to a drive shaft turned by a low-speed, high-torque hydraulic motor controlled by a hydraulic flow control valve rather than by a ground-engaging wheel.

Abstract: KEY SIGNAL ENCRYPTION AND DISTRIBUTION SYSTEM FOR      CONTROLLING SCRAMBLING AND SELECTIVE, REMOTE DESCRAMBLING OF TELEVISION SIGNALS            ABSTRACT OF THE DISCLOSURE    A  system  and  method  for  scrambling  and  selectively descrambling  television  signals  that  are  transmitted  to subscribers'  descramblers  in  a  subscription  television system.  A working key signal is generated by processing an "initialization vector"  signal in accordance with the DES algorithm upon the algorithm being keyed by either a common category  key  signal or  some other  key signal.  A unique encryption  keystream  is  generated  by  processing  the initialization  vector  signal  in  accordance  with  the  DES algorithm upon the algorithm being keyed by the working key signal.   A television  signal  is  scrambled  in  accordance with the unique encryption keystream to provide a scrambled television  signal.   A  plurality  of  unique  encrypted category  key  signals  individually  addressed  to  different selected   subscribers'   descramblers   are   generated   by processing  the  initial  common  category  key  signal  in accordance with the DES algorithm upon the algorithm being keyed by a plurality of different "unit key" signals unique to   different   selected   descramblers.    The   scrambled television  signal,  the  initialization  vector  signal,  and the  plurality  of  encrypted  category  key  signals  are broadcast to the descramblers.  A corresponding tier of DES algorithms are employed at the descrambler to reproduce the encryption  keystream;  and  the  TV  signal  is  descrambled in  accordance therewith.   Each descrambler has its unique unit  key  signal  stored in a secure  memory  for  use  in reproducing   the  common  catagory  key  signal  when  the descrambler  is addressed by its unique encrypted  cateaory key signal.
