Abstract: GEOMAGNETIC PROSPECTING SYSTEM AND METHOD                  ABSTRACT OF THE DISCLOSURE          A geomagnetic prospecting system and method are dis-closed to determine the presence of hydrocarbon-bearing sub-strata below the surface of the earth.  A plurality of sta-tion sites are selected each having angle measuring means and each angle measuring means having first and second magnetic field detection units perpendicular to each other. The first detection unit measures the vertical inclination angle, i.e., the magnetic dip needle angle of inclination, and the second detection unit measures the horizontal declination angle from true north.  Each detection unit is mechanically or electri-cally adjusted to be substantially on a null of the magnetic field of the earth, and preferably is adjusted slightly off null to a more sensitive portion of the field detection pat-tern. Readings of the inclination and declination angles are taken substantially simultaneously at the plurality of sta-tion sites, and the presence of hydrocarbon-bearing substrata is indicated if both inclination and declination angles move toward negative in a one to ten-minute time period, "nega-tive" being defined as an inclination angle reducing the angle toward north and an eastern declination angle change toward west.  This gives an immediate indication of the probable presence or absence of hydrocarbon substrata, so that a traverse line of station sites is not required, but, instead, one may move at random toward areas on the surface of the earth which continue to give promising results.  The foregoing abstract is merely a resume of one general applica-tion, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: ABSTRACT        Disclosed is a method and structure for the simultaneous trans-mission of voice and data information over the same PCM transmission channel. In the present invention, analog voice information is sampled at a first sampling rate, during periods when voice information is to be transmitted at a frequency which provides a digitized voice rate equal to the trans-mission rate capability of the transmission channel.  During periods when both voice and data are to be transmitted, the analog voice information is sampled at a second sampling rate less then the first sampling rate, thus allowing the merged voice and data information to have a total digitized transmission rate equal to the transmission rate capability of the trans-mission channel.

Abstract: ABSTRACT OF THE DISCLOSURE         A growth substrate bed suitable for growing plants, which is easy to handle and transport is provided herein.  Such a bed consists essentially of a flexible, rollable, container capable of assuming a first rolled configuration and a second unrolled configuration.  A dry particu-late growth medium in pellet form capable of swelling when water is added thereto is in the container.  The growth medium  when its dry, unswelled state is evenly distributed in and partially fills the container when the container is in its rolled configuration.  In addition, the growth medium when in its wetted, swelled state substantially fills the container when the container is in its unrolled configuration.  The container when in its rolled configuration is held sufficiently tight to prevent a sub-stantial displacement of the dry growth medium during handling and trans-portation of the container.  Consequently when the container is unrolled to assume its unrolled configuration and the dry growth medium is wetted, the growth medium needs no repositioning.

Abstract: ROUND BALE UNROLLER            ABSTRACT OF THE DISCLOSURE     Round bales require to be unrolled in order that the contents are available to the cattle and usually they are unrolled by mounting same in a frame and then towing the frame behind a tractor.  The present device is mounted at the front of a tractor and includes a frame with two spaced and parallel prongs for spearing the bale in order to move it in position from a storage area. When in the desired location, the prongs are withdrawn and one of the prongs is engaged axially with the bale. The prong is then lowered until the periphery of the bale engages the ground at which time it is unlatched.  The tractor is driven forward and to one side thus moving the bale and prong through approximately 90  so that the axis of the bale is perpendicular to the direction of travel. Driving the tractor forward unrolls the bale raising the frame which is tilted forwardly, causes the prong to swing forwardly and latch automatically.

Abstract: PRECIPITATION OF PROTEINS FROM SALT-CONTAINING   PROTEINACEOUS FLUIDS EMPLOYING A DESALTING       TREATMENT, AND USE THEREOF IN   SELECTIVE PLASMAPHERESIS             ABSTRACT OF THE DISCLOSURE       Total or fractional precipitation of proteins from salt-containing proteinaceous solution or sus-pension mixtures is induced or enhanced by subjecting the proteinaceous mixture to a desalting treatment, for example, by electrodialysis.  In one aspect of the invention, the desalting treatment is used in conjunction with the addition of heavy metal ions to the proteinaceous mixture to provide a synergistic effect on the precipitation of the protein fraction. In another aspect of the invention, the desalting treatment, either with or without the heavy metal ion additon, is employed as an integral part of a selective plasmapheresis procedure for the removal or recovery of one or more selected plasma proteins from blood plasma.

Abstract: VERTICAL LIFT DRIVE ARRANGEMENT Abstract of the Disclosure A vertical lift platen is moved by a driven shaft between lower, intermediate and upper vertical positions.  The platen dwells at zero speed at each position.  The speed increases to a maximum speed and then returns to zero speed as the platen moves between positions.  A cam member mounted to the driven shaft supports a circumferentially arranged series of three identical cams.  Each cam includes a pair of radially extending linear cam edges and a pair of arcuate edges, each tangent to the outer terminus of a linear cam edge.  A roller support rotatably supports a pair of cam rollers at defined distances from the axis of a driving shaft to which it is attached.  The driving shaft axis is parallel to the driven shaft axis.  As the roller support rotates with the driving shaft, the cam rollers initially roll around the arcuate edges of the first cam to maintain the platen at zero speed. Then, one roller rolls radially inwardly and then radially outwardly of one linear edge of the first cam to move the platen from lower to intermediate vertical position with the speed increasing from zero to a maximum and then back to zero.  Next, the rollers roll along the arcuate edges of the second cam, and then the other cam roller moves radially inwardly and then radially outwardly of one linear edge of the second cam to move the platen to the upper vertical position, with the speed increasing from zero to a maximum and then back to zero.  The cam rollers then roll along the arcuate edges of the third cam to maintain zero speed.

Abstract: S P E C I F I C A T I O N            "Improvements in or Relating to the Forming of Extrusion Dies"     ABSTRACT OF THE DISCLOSURE         A method of forming an extrusion die comprises forming an extrusion aperture in a die piece, forcing a flowable material partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture, by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location.  The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.
