Abstract: ABSTRACT OF THE DISCLOSURE    A hydraulically actuated jam release system for a jaw type rock crusher wherein a massive, mechanically rigid retracting plate is disposed behind the crusher's stationary jaw to engage the entire width of the jaw to hold the stationary jaw in its operative position.  Mechanical locking pins are hydraulically actuated by vertical hydraulic cylinders to mechanically lock the retracting plate in its forward position, and separate horizontal hydraulic retracting cylinders are provided to retract the retracting plate when the mechanical locking pins are disengaged therefrom, and to return the retracting plate to its forward position after the non-crushable material has been released from the crushing chamber of the crusher.  The entire hydraulic system for the jam release is hydraulically operated through a series of suitable hydraulic valves prefereably located at a central control station.  It is an important aspect of the disclosure that once the retracting plate is mechanically locked by the locking pins, the stationary jaw does not require hydraulic pressure.

Abstract: DYNAMIC READ REFERENCE VOLTAGE GENERATOR                             Abstract A method and circuitry (5) for enhancing the reproducibility and reliability of circuitry for reading a memory array (10a, 10b, 10a', 10b') provides a dynamically generated reference voltage for the sensing circuitry.  The invention senses the highest word line voltage and communi-cates a voltage derived therefrom to the sensing circuitry (26, 27, 28, 29; 26', 27', 78', 29'; 32, 33) to provide a reference voltage.  A voltage clamp (62) is coupled to the circuitry for communicating the highest word line voltage (50) to prevent the reference voltage from following the word line too low during transitions.  The invention is rendered compatible with the existing write circuitry associated with the memory array (10a, 10b, 10a', 10b') by the provision of disabling circuitry (65) coupled to the communicating circuitry (55, 57) and to the clamp (62).  The disabling circuitry (65) is responsive to a write control signal and operates to prevent the high word line voltage from being communicated to the sensing circuitry, and fur-ther operates to allow the communication of lower voltage than would normally be permitted by the clamp (62).

Abstract: ABSTRACT OF THE DISCLOSURE A  tractor  draft  load  monitoring  system responsive  to tractor and associated implement  load changes.   The  system is  particularly adapted  for  a tractor  having  an  engine/transmission  power  unit coupled to its drive shaft.  The power unit is mounted on the frame by resilient mounts that permit measurable angular displacement of the power unit relative to the frame about the drive shaft axis in reaction to changes in the drive shaft torque.  The working depth of the implement, which may be tractor mounted, semi-mounted or a pull type implement,  is raised or lowered by a hydraulic lift system that is controlled by a control valve assembly connected to a source of fluid under pressure.   Interposed between the power unit and the control valve assembly is a transmission cable (Bowden wire  type)  and  lever  system  that  is  operative  to transmit angular displacement of the power unit to an actuating member of the control valve assembly to cause hydraulic actuation of the hydraulic lift device to change the working depth of the implement to compensate for changes in its draft load. The specific hydraulic circuit for actuation of the hydraulic lift device is disclosed.

Abstract: A B S T R A C T     According to the invention the chemical losses in the pulping process are covered by the addition of residual solutions from other processes containing appropriate chemicals, to the final evaporator in the spent liquor evaporation process. This avoids salts being deposited on the heating surfaces, which occurs when the residual solutions are added to the weak liquor as in one of the methods used today. Capacity losses are avoided and the thermal eco-nomy is improved.            In the other method currently used, residual solutions are added to the concentrated waste liquor before the spraying into the soda recovery boiler, the concentrated waste liquor being diluted. However, in the method according to the inven-tion there is no such dilution, resulting in better thermal economy.

Abstract: ABSTRACT "Self-adaptive equalizer for baseband data signals."     A self-adaptive equalizer is employed in a data modem for correcting in the baseband a received data signal. The equalizer comprises a difference circuit for determining the difference between a received signal and a correction signal formed at a sampling frequency by a transversal filter having adjustable coefficients, and for producing a corrected signal which is applied to a decision circuit. The output of this decision circuit is applied to this transversal filter whose coefficients are adjusted so as to minimize the mean-square value of an error signal. This error signal at an actual sampling instant is determined by forming the difference between the value of the corrected signal at that sampling in-stant and the value of the corrected signal at a previous sampling instant, previously multiplied by the ratio be-tween the value of the recovered data at the actual sampling instant and the value of the recovered data at the previous sampling instant.

Abstract: ELECTRONIC POSTAGE METER RESET CIRCUIT     Abstract of the Disclosure A reset circuit for an electronic postage meter controls the operation of the reset line of the meter's computing system.  The reset circuit operates in conjunction with a non-volatile memory protection circuit.  The inter-relation of the reset circuit and non-volatile memory protection circuit protects against the possible loss of postage funds due to spurious data being written into the non-volatile memory.  The reset circuit operation is con-trolled in part by the voltage levels applied to the non-volatile memory.  This insures that the reset to the elec-tronic postage meter computing system is released during power-up of the meter after proper voltage levels have applied to the meter's non-volatile memory and reestablished during low power or power-down conditions.

Abstract: ABSTRACT OF THE DISCLOSURE             Targets   of   readily   saturable   magnetic material and mounted on protected articles are detected when taken through an interrogation zone in which an alternating magnetic interrogation field is generated by  transmitter  antenna coils.  The  target  is  driven alternately into and out of saturation and it disturbs the  alternating  magnetic  interrogation  field  in  a manner so as to produce alternating magnetic fields at frequencies which are harmonics of the frequency of the alternating magnetic interrogation field. The composite of   these   alternating   magnetic fields   has   a characteristic  asymmetry  due  to  the  effect  of  the earth's  magnetic  field.  The  target  responses  are detected by receiver antenna coils  to produce  first detection signals which are processed in a compressor and  a  signal  average  to produce  asymmetry  signals which  are compared  in  a  comparator  with  the  first detection signals to produce alarm signals.
