Abstract: HYBRID SUBBAND CODER/DECODER               METHOD AND APPARATUS.            ABSTRACT OF THE DISCLOSURE         The subband channels of a subband coder/decoder utilize different encoding/decoding algorithms so as to maximize overall signal transmission quality using a digital signal processor having limited digital memory capability.  In the exemplary embodiment, a digitized 180-2900 Hz voice band signal is divided into four octave-spaced subbands.  The highest frequency subband (1450-2900 Hz) is encoded/decoded using a block companded pulse code modulation (BCPCM) algorithm while each of the lower frequency subbands is encoded/decoded using an adaptive pulse code modulation (APCM) or an adaptive differential pulse code modulation (ADPCM) algorithm. The resulting "hybrid" vocoder tends to maximize the quality of transmitted voice signals while yet permitting implementation within constrained digital memory capacity and/or constrained transmission channel bandwidth.

Abstract: ABSTRACT New and improved techniques, systems and equipment for the practical underground mining of petroleum from both virgin and depleted oil fields under certain geological conditions, are described.  A method of drilling relatively small diamter, drainage-type oil wells using a fluid and cutting control assembly from within an access underground drilled tunnel, is provided.  The fluid and cutting control assembly facilitates the safe underground drilling and installation of the small diameter, drainage-type oil wells which can be operated either under the natural pressures occurring in the geological strata, as gravity drain wells or by suitable secondary treatment measures arti-ficially pressurized to facilitate drainage of oil from oil bearing strata into which such wells are drilled. Techniques and equipment to facilitate the safe drilling of such wells, placing them into production and thereafter controlling operation of the mine workings in a safe and reliable manner, is described, together with the control system, sensors and other equipment required for safe installation and operation of an underground petroleum mine.

Abstract: ABSTRACT OF THE DISCLOSURE        Cells are normally separated by velocity sedimentation and/or density gradient centrifugation, counter current distri-bution or selective agglutination.  The cells may also be separated using a multi-sectioned plastic sleeve defined by a plurality of plastic cylinders with screens and O-rings therebetween and a retaining plate at the top end of the cylinders.  These methods present various problems including a large variation in the sizes of cells isolated in any fraction, high costs of materials, and/or exposure of the cells to air immediately following separation. These problems are overcome by means of a simple cell separator which permits separation on the basis of size, and which is sealed maintaining a sterile environment during the separation process.          The separator includes an elongated, tubular casing with an open upper end and a closed lower end, an elongated, tubular column for insertion into the casing, the column having a closed upper end and an open lower end, the column including a plurality of separate interconnectable tubular sections for releaseably support-ing cup-shaped filters between adjacent sections, and a flange on the uppermost section for sealing engagement with the upper end of the casing.  Cells in a liquid medium are introduced into the column through an inlet duct in the close upper end of the column.          The cells are separated by means of the filters, and the liquid medium is discharged through an outlet duct in the lower end of the casing.  Thus, the column can be inserted and removed from the casing as a unit, and disassembled from the upper or lower end thereof.
