Abstract: AUTOMATIC RESETTING CONTROL CIRCUIT      FOR AIR SWITCH OPERATOR            Abstract of the Disclosure An automatic setting subcircuit is disclosed in a remotely actuated power distribution switch control circuit characterized by a two-position electromechanical control for an automatic actuation mechanism for operating the switch.  The control is provided with two elements, each for moving the control in an opposite direction between the open and closed positions of the switch.  The circuit includes a first energy storage capacitor for storing energy received from a source remote for the circuit.  A first thyristor, when triggered by a locally generated control signal, applies the energy stored in the first energy storage capacitor to one of the elements to cause the switch to be operated in a predetermined direction.  The automatic resetting subcircuit includes a second energy storage capacitor for storing energy received from the remote source with the second energy storage capacitor being electrically isolated from the first thyristor.  A sensor switch responds to the position of the distribution switch and is connected to reverse the connections of the first and second energy storage capacitors in accordance with the position of the power distribution switch.  A time delay circuit is provided in conjunction with a second thyristor which is connected to the second energy storage capacitor and to the sensor switch.  The gate of the thyristor is connected to the time delay circuit and to a transistor base controlled by the voltage on the first energy storage capacitor,  If the voltage thereon goes to zero, indicating a signal switch, and the power distribution switch does not operate, the second thyristor passes the energy stored in the second energy storage capacitor to the other element of the electromechanical control to return the control to its initial position.

Abstract: APPARATUS FOR THE REVERSAL OF A HOT ROLL IN A FUSING ASSEMBLY            ABSTRACT OF THE INVENTION:           Apparatus in a copier fusing assembly for dis-tributing the wear on a hot roll occasioned by the use of variable length copy sheets.  This wear is distributed over the entire horizontal length of the hot roll by reversing the hot roll, end-for-end.  Easy reversal of the hot roll is made possible by utilization of a hot roll subframe which is removably mounted in the copier fuser mainframe.  A handle on the subframe allows for manual removal of the subframe and hot roll from the mainframe and out of the copier where they are reversed and inserted back into the mainframe.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for producing fiber pulp of improved paper-forming characteristics from ligno-cellulose-containing material such as wood chips and the like.  The pulp material is subjected to a defibrating process in at least two steps.  In the first step, the pulp material is disintegrated in a de-fibrator to form a flocculent mass of initially separated and freed fibers.  This flocculent mass is then passed through a screw compacting device in which it is subjected to compression of a magnitude of 1 to 5 times the volume of the initially sep-arated fibers.  The compressed and highly concentrated mass of initially separated fibers is then passed into a refiner wherein the fibers are finally separated and fibrillated to form the final pulp.

Abstract: IMPROVED TONE DECODER Abstract of the Disclosure An improved decoder for providing a decoder output signal when a tone signal contains frequencies that are sequentially within a predetermined passband surrounding first and second detection frequencies f1, f2. A tone signal is mixed with a reference signal which alternates, at a multiplex frequency, between sine and cosine signals, each being at a predetermined reference frequency which is less than the multiplex frequency. A tone switching logic circuit normally maintains the reference frequency at a value substantially equal to the frequency f1. The mixed signal is coupled through a demultiplexer to respective inputs of first, second, third and fourth low pass filters, each of which has a cut-off frequency which is one-half of the decoder passband The respective outputs of the filters are coupled through a multiplexer to a squarer. Normally, the demultiplexer and the multiplexer are controlled by the tone switching logic circuit so as to alternately couple, at the multiplex frequency,the mixed signal to the inputs of the first and second filters, and the outputs thereof to the squarer. The squarer output is applied to a summing amplifier, which removes the multiplex frequency, and which provides a dc signal which is applied to a comparator. When the value of the dc signal exceeds a threshold value, the comparator provides a first output signal which causes the tone switching logic circuit to change the reference frequency to the frequency f2, and to control the demultiplexer and multiplexer so that the mixed signal is thereafter alternately coupled, at the multiplex frequency, to the inputs of thethird and fourth low pass filters, and so that the outputs thereof are alternately coupled, at the multiplex frequency, to the squarer. A decoder output signal is provided, however, only if a second output signal from the comparator is provided within a predetermined period of time following the provision of the first output signal therefrom. The reference signal is preferably provided by a sine/cosine generator from pulses provided by a divide-by-N counter occurring atthe multiplex frequency, with the divisor N being controlled by the tone switching logic circuit.

Abstract: In order to compress the sludge layer of an industrial process tailings pond beyond the density which it will naturally reach after treatment by the addition of hydrolyzed starch flocculant, sand is distributed over the sludge layer as a water permeable surcharge which, by weight, further compacts the sludge to obtain additional dewatering. The hydrolyzed starch flocculant provides improved shear strength and permeability characteristics to the sludge layer such that it can support the sand surcharge.

Preventing the belt from deviating laterally from the pre-determined path deflects  the portion of the fins providing support for the belt.  The deflected portion of the fin returns to the undeflected condition when not supporting the belt.  In this manner, the maximum force applied to the belt never exceeds the minimum force required to buckle the belt.
