Abstract: ABSTRACT OF THE DISCLOSURE          A read only type optical disc, and disc drive apparatus for reading/additionally writing data into the disc.  The disc has a recording material formed in all of the tracks by which data can be additionally recorded on the disc.  This optical disc has a plurality of sectors forming a data read-only area and a write/ read area.  Each area has track sectors each having a sector identifier portion in which address information is recorded and a data field portion to record data.          Data-field identification flags indicative of the read-only area and the write/read area are recorded in the respective identifier portions.  On reading or writing this optical disc, the data field identification flag is detected to identify the kind of related area i.e., read-only area or write/read area.  Thus, it is possible to avoid erroneous recording of data into the read-only area.  Upon reading operation, waveform equalization and binary-clipping level of reproduction signals can be well controlled.  The gain of the servo loop can be switched.  The track searching operation can be stably performed.  The data reading and data writing into the data write/read area can be improved.

Abstract: ABSTRACT        A process for converting landfill gas to high concentration carbon dioxide gas involves combusting the landfill gas in admixture with oxygen or an oxygen rich gas in an internal combustion engine, gas turbine, boiler or other energy conversion device.  In a first embodiment of the invention, a portion of the combusted exhaust gas is recycled in order to control the maximum temperature achieved during combustion.  In a second embodiment of the invention, the majority of the methane in the landfill gas is separated and then the remaining gas is combusted in admixture with oxygen or oxygen rich gas in an internal combustion engine, gas turbine, boiler, or other energy conversion device.  In this second embodiment, the peak temperature achieved in the combustor is controlled by appropriately selecting the amount of methane removed.  The present invention increases the amount of carbon dioxide available from a given landfill gas by converting all or part of the contained methane to carbon dioxide and water. The gaseous carbon dioxide so produced is suitable as feed to a conventional carbon dioxide liquefaction plant for producing liquid food grade carbon dioxide.

Abstract: METHOD AND CIRCUIT FOR PROCESSING NARROW BAND SIGNALS     LOCATED IN A WIDE  BAND HAVING DISTURBANCE                 Abstract of the Disclosure A method and a system for processing information signals  contained  in  a plurality of  contiguous  energy bands of a wide band signal generated by photon emission or absorption, such as from a gamma or X-ray source, and containing  desired  information  signals  and  undesired noise signals.   A radiation detector accepts this photon emission and produces position signals and energy signal representative  thereof.   The method and the system of the present invention consists in directing the position signals in a predetermined one of a first plurality of storage banks corresponding to the contiguous energy bands.          The position signals are directed and cumulated into spe-cific ones of the banks as determined by the level of its  corresponding  energy  signal.   The relation between accumulated position signals in these banks is evaluated by comparing the signals in each bank with every other ones  of  the banks and rating said relation of signals between banks.   The information which is accumulated by these position  signals  is  then  selected  in  accordance with their ratings to minimize similarities between accu-mulated signals.   This rated information is then trans-ferred to a second plurality of storage banks which are classified  in  accordance with the  nature  of the rated signals whereby to isolate desired signals from undesired noise signals.   The signal information is then weighted by optimum compression transformation to produce an inter-pretable signal representative of the desired information contained in the photon emission or absorption.

Abstract: ABSTRACT OF THE DISCLOSURE Control of a plurality of relay drivers by smart control devices and the continuous status monitoring of a plurality of switches and associated smart sensor wherein each smart control device and each smart sensor is connected at a separate single point on a single-wire bus, are affected by a smart control and sensor device multiplex system. The system employs a microcomputer and a driver and receiver circuit for developing a particular offset square wave pulse train which is placed on the bus to provide power and control voltage signals to the plurality of smart contro? devices and smart sensors. The smart control devices contain circuits that respond to the wave form in a manner that causes each smart control device to drive an associated relay driver after a chosen number of polling cycles. Current signals are sent over the bus back to the driver and receiver indicative of the status of the smart control device. The smart sensors contain circuits that respond to the waveform in a manner that causes each smart sensor to send current signals back over the single wire bus to the driver and receiver circuit and then on to the microcomputer during designated repetitive and sequential time slots. The driverand receiver circuit receives, interprets and converts the current signals from the smart control devices and the smart sensor into voltage signals used by the microcomputer for establishing a history of the status of the bus, the control devices, the sensors and the switches. The microcomputer supplies continuous andupdated information to a display system indicative of the status of each controldevice and each sensor and its associated switch.

Abstract: "SHEAR COUPLING ASSEMBLY"                 ABSTRACT OF THE DISCLOSURE         A shear coupling assembly is provided for connecting the rod of a downhole pump with the terminal member of a sucker rod string.  The assembly involves two parts or coupling members which are threadably connected end to end during normal operations but which can relatively easily be parted if the pump becomes stuck, by pulling up on the still free sucker rod string. The first coupling member has a pin end incorporating an externally threaded head and a shear neck, of relatively reduced diameter, joining the head to the main body of the coupling member. The head has an axial, internally threaded counterbore, so that a tensioning tool may be screwed thereinto, the other end of the coupling member may be held, and the tool may be pulled to place the shear neck in tension. The second coupling member is a sleeve forming an axial bore therethrough.   The second coupling member is adapted to thread onto the head of the first coupling member.   To prepare the assembly for use, the tensioning tool is inserted, the sleeve is slipped over the tool, the tool is pulled to place the neck in tension, and the sleeve is threaded along the head until it abuts the main body of the first coupling member. The tensioning tool is then removed.  The sleeve functions to hold the shear neck in a tensioned state.   The tensioned neck is better able to sustain cyclic compressive loading in the course of reciprocation of the sucker rod string.
