Patent CA-1103656-A (CA)
Inventor: JOHNSON GARY R
IPC: E21B17/00
Filed: 1979-12-11
Granted: 1981-06-23
Abstract: ABSTRACT OF THE DISCLOSURE         The method is disclosed for drilling a pilot hole and subsequently enlarging the pilot hole in earth formation.          A dual concentric pipe string is used for circulating air down-wardly through the outer pipe, through a pilot bit and upwardly through the bore hole outside the pipe string to bail cuttings, during drilling of the pilot hole. The air pressure expands the cutters of an expansible bit while a milited portion of the air supplied cools the cutters.  After the cutters are fully expanded, additional air is utulized to clean and cool the cutters.          Air is returned through the inner pipe of the dual concentric pipe string.  A venturi device is utilized to induce return flow through the inner pipe during enlargement of the hole and to vacuum residue when enlargement is completed.  The dual concentric pipe string is made up of lengths of pipe providing threaded, sealed joints.

Title: Dc-free encoding for data transmission system
Inventor: MILLER JERRY W
IPC: H03M5/04
Filed: 1980-01-30
Granted: 1980-12-16
Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus provide for the elimination of any net DC component from the transmission of binary data sequentially in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., O's, are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., l's, are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.  The onset of a sequence of second bit states following a first bit state that might introduce a DC component into the transmitted signal with normal transmission is detected by producing a first indicating signal, and in response to the first indicating signal, the state of a current bit and the state of the next succeeding bit, the transmission of signal transitions is modified to eliminate any DC component.  The end of a sequence of second bit states that would introduce a DC component is detected by producing a second indicating signal utilized to modify the signal transitions at the end of a troublesome sequence, as by suppressing the transition corresponding to the last second bit state in such a sequence.

Abstract: ABSTRACT OF THE DISCLOSURE The changer includes a filter supporting frame attached to a supply spool containing fresh filter material and a take-up spool for storing the clogged filter material. The frame is substantially rectangular in shape and has attached thereto a sensor switch which is disposed medially of the frame and the filter material disposed thereacross.  The switch is actuated when the filter material become a clogged to a point where deflected inn of the material in response to circulating air flow occurs. The switch actuates a drive motor attached to the take-up spool causing the take-up spool to wind the clogged material thereon thereby replacing it with clean filter material from the supply spool. The filter material itself contains transverse enlarged linear elements which are longitudinally spaced along the filter material at intervals equivalent to the width of the frame. The enlarged areas actuate a switch which causes cessation of the motor drive, thereby insuring accurate placement of the fresh filter material.

Abstract: DIMENSIONAL SOUND PRODUCING                  APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE     The present invention comprises a sound reproducing system having right and left speakers, S(R) and S(L), respectively, which produce right and left stereo sounds, respectively.  A right stereo signal, in addition to driving the right speaker, is inverted and delayed to produce a compensating signal which is transmitted to the left speaker to produce a delayed compensating sound pattern from the left speaker.  The signal for the left speaker is inverted and delayed in a manner to produce a compensating sound pattern from the right speaker.  The compensating sounds substantially cancel the main stereo sounds travelling to a person's ear that is further from that speaker, to produce a dimensionalized effect where some of the sounds appear to be outside of the speaker area.  In a second embodiment, the main stereo signals and the compensating signals are used to produce a recording, which in turn produces the main stereo sounds and the compensating sounds to produce a dimensionalized effect.

Abstract: ABSTRACT TO THE DISPLOSURE :           Devolatilizable fine-grained material which contains hydrocarbons is devolatilized by means of fine-grained solids which have been heated to temperatures of about 500 to 1000°C.          The devolatilizable fine-grained material (conduit 5) is mixed with the heated solids (from conduit la) and is thus heated to temperatures of about 400 to 900°C.  The mixture is passed through a dwell zone (6), and gaseous and vaporous devolatili-zation products are withdrawn (conduit 8) and cooled. The heated solids are fed to the dwell zone as a loosened stream in a trickling and/or agitated state of motion, and the devola-tilizable fine-grained material is introduced into said stream in order to be admixed thereto.  The heated solids and the de-volatilizable fine-grained material can be mixed in a weight ratio of 3:1 to 12:1.  The stream of trickling heated solids can be deflected at least in part.

A ROM is connected to the CPU and ROM contains a program for controlling the operation of the CPU.  A real time clock is connected to the CPU for determining sequential predetermined time periods.  Three input terminals are connected to the CPU for receiving data to be stored in a RAM.  One of the three input terminals has pulses impressed thereon, the number of pulses being representative of electric power consumption.  The one input terminal is also connected, via the CPU to a time-of-day memory.  The memory is comprised of a plurality of discretely addressable registers wherein the CPU equates each addressable register sequentially with a consecutive one of the predetermined time periods, so that each register sequentially contains a count which is representative of the power consumed during its associated time period or any fraction thereof.  The CPU activates the transmitter to transmit data upon receipt of the external instruction.          The data is, in part, the contents of each register in the time-of-day memory transmitted in sequence.
