Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns a method of surface mining along an elongated pit using a cross-pit conveyor for trans-ferring selected excavated material, such as topsoil, directly across the pit while using a separate overburden excavator to transfer the remaining overburden.  The method uses a cross-pit transporter which is supported solely on the working bank, includes a cantilevered conveyor which extends completely across the pit, and is slewable so it can periodically swing to a non-interfering position when passing the other excavator.  The method allows the selective replacement of the different over-burden materials in accordance with modern reclamation practice.

Abstract: TREATING PULP WITH OXYGEN                ABSTRACT OF THE DISCLOSURE         A wood pulp slurry is treated with oxygen in a mill with little change to the process or structure of the mill.  No special pressure tanks are required. The consistency of the pulp need not be altered for the treatment step.  It may be treated at the usual process consistency of the pulp; e.g., it may be treated at the usual consistency of the pulp leaving a washer or subse-quent steam mixer without additional dewatering or addi-tional dilution.          The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmos-phere.  Alkali should also be present when the oxygen is mixed with the slurry.  The mixing should occur near to the point of oxygen addition.          The pulp is treated with oxygen several times during a sequence.  Some sequences are O-X-O and O-O-X-O in which X may be a hypochlorite, a peroxide or ozone. The sequence may be followed by a D stage.          Specific mixer designs are also disclosed.

Abstract: ABSTRACT      The apparatus comprises a trough and a pressure pump attached to the trough. There are freely heaped up on the bottom of the trough pebbles of different shapes and dimensions. Lukewarm water is supplied by the pressure pump into the trough. As the transition inside surface between the bottom and the walls of the trough is rounded, the pebbles can move when walking thereon. The water is warmed up in the trough and circulated under pressure. The effect of the apparatus when walking on the pebbles is the same as treading water in stone brooks. In this way the foot reflex zones are automatically massaged.

Abstract: METHOD AND APPARATUS FOR COMMUNICATING DIGITAL INFORMATION WORDS BY ERROR-CORRECTION ENCODING                  ABSTRACT OF THE DISCLOSURE        A method and apparatus are provided for communicating a sequence of digital information words.  The information words are separated into a sequence of odd information words and a sequence of even information words.  The separated odd and even information words are time-displaced from each other by a predetermined amount.  The odd information words are encoded in an error-correcting code, and the even information words are separately encoded in a similar error-correcting code.  The encoded time-displaced odd and even information words are combined into a transmission block, and this transmission block is transmitted or recorded.  In one embodiment, the information words are encoded by generating an error-correcting word in response to the odd information words and by generating an error-correcting word in response to the even information words,  The respective error-correcting words are interleaved with the odd and even information words.         To recover the original information words, the transmission block is received and the odd and even information words are decoded so as to correct errors therein.  The time displacement between the decoded odd and even information words are removed.          If an information word contains an uncorrected error therein, a correct information word is approximated therefor by interpolating adjacent decoded odd or even information words -i-so as to approximate a correct even or odd information word, respectively.  A corrected sequence of information words formed of the decoded and approximated information words is recovered.                             -ii-

A bandpass filter, tuned to the intercarrier sound signal frequency, has an input, and an output coupled to the input of the sound processing circuitry.  A detector is provided for producing detected video frequency and intercarrier sound signals.  First and second signal paths are coupled between the output of the detector and the input of video processing circuitry, the second signal path including a first reactive impedance element of one sign.  A third signal path is coupled between the second signal path and the input of the bandpass filter and includes a second reactive impedance element of an opposite sign.  A fourth signal path is coupled between the junction of the third signal path and the input of the bandpass filter and a point of reference potential, and has an impedance which is significantly less than the impedance of the third signal path at the intercarrier sound signal frequency.  The four signal paths comprise a tuned circuit which attenuates the intercarrier sound signal at the input of the video processing circuitry. The combined sound trap and take-off network is tuned by varying a single adjustable inductor in the shunt leg of the network.

Abstract: INTERLOCKING TRUNCATED TRIANGULAR INSULATOR         Abstract A two-piece, interlocking insulator suitable for covering a truncated triangular pipe, the conforming insulator having a base unit, a pair of side walls convergingly extending from the ends of the base unit and terminating with an apex unit.  The insulator can closely conform to the perimeter of the truncated triangular pipe or, as in another embodiment, to a ceramic fiber blanket located around the perimeter of the pipe.  Each segment of the insulator has a body and a pair of spaced apart arms.  When the two segments are longitudinally and conformingly aligned around the pipe, they can be urged together to form an interlocking, insulator which remains around the pipe without any other means of support.          When two truncated triangular pipes are aligned so that their base members are contiguous, an additional embodiment of the insulator includes a pair of segments each having a double-angle side wall, a pair of arms partially integral with and partially spaced apart from the double side wall by corresponding recesses and a void corresponding to the remaining double side wall so that as the two segments are conformingly aligned around the pair of pipes, they can be urged together to form an insulator covering.          The insulator can further be used with a truncated tri-angular pipe having a pair of shoulders extending outwardly from each side of the apex member and having a ceramic fiber blanket located around both side members and the base member of the pipe.

The assembly is utilized for retaining and guiding a drill steel on a roof bolt-ing machine during the collaring of the drill steel in the mine roof.  Once collared, the drill steel is re-leased by the retaining assembly inasmuch as the latter is not necessary for support purposes after collaring has occurred.  The release of the drill steel from the retaining assembly is accomplished when the vibrations from the drill steel are sufficient to open the support mechanism once the drill has been collared.
