Abstract: ABSTRACT OF THE DISCLOSURE         A method for the determination of bilirubin in liquid samples, particularly biological liquid samples.  An assay method, as well as an analytical element, is disclosed.          In accord with the assay method there are contacted together a liquid sample containing biliribin as analyte and an interactive composition containing a biliribin-active complex, the complex comprising a diffusible, bilirubin-displaceable, detectable ligand bound to a carrier which can also bind bilirubin.  As a result of a competitive binding-displacement interaction between bilirubin and the complex, bilirubin binds to the carrier and displaces detectable ligand which can be selectively detected and used to determine the presence or amount of bilirubin.  Appropriate carriers and detectable ligands can be chosen on the basis of their first order binding constants.

Abstract: ABSTRACT         A mixture of pieces or fragments of different materials and different sizes is separated into two or more fractions.  The mixture is charged from above to a part located between the centre of an inclined shaking table.  The shaking table performs alternative movements, derived from a rotary motion in the direction of the shaking table surface and up and down, preferably perpendicular to the same surface respectively.          The shaking table has friction elements, so that, as a result of rebounding from the shaking table to the one side and being taken along by the friction elements to the other, one fraction is driven to the lower end of the table and the other fraction is driven to the upper end of the table.  The shaking table is arranged about at least two shafts and has at least one, preferably two, somewhat inclined surfaces which are inclined downwards towards the lower end of the shaking table at an angle which is more steeply inclined than an imaginary line connecting the two shafts, so that rebounding, heavy pieces and fragments bounce down to the lower end of the apparatus.          The inclined surfaces can be arranged with openings.  Moreover, the shaking table can be provided with two or more regions of inclined surfaces, the sizes of the openings of the different regions increasing in a direction towards the upper end of the shaking table.

Abstract: CARDIAC IMAGING WITH CT SCANNER                 Abstract of the Disclosure The patient's ECG signal is employed in a traverse-and-rotate type CT scanner as a time base for triggering the beginning of a traverse such that the traveling beam reaches the heart at a desired phase of the cardiac cycle.  For a purely-rotational-type CT scanner, continuously generated scan data is only stored for corresponding phases of successive cardiac cycles. Alternatively, gating of the beams themselves can be controlled by the ECG signal.  The use of a pacemaker to stabilize the cardiac period is described along with a system for recognizing unacceptable variations in the cardiac period.  In a traverse-and-rotate-type fan-beam CT scanner, the effective beam width is narrowed to hasten the traverse of the heart.

Abstract: ABSTRACT Disclosed is a two-wire telephone testing system employing a low frequency test signal which is a submultiple of the power line frequency. This test signal is applied between the two-wires or between either wire at a point of potential reference (ground).  A measure of the integrated value of the current between the connected points is then made for a period equal to one-half cycle of the applied signal with one polarity and one-half cycle with the polarity of the measured signal reversed.  The integrated periods are selected to be in phase with the applied signal for determining conductance and 90° out of phase for determining susceptance.  Direct current measurement can also be made for the same time periods.

Abstract: ABSTRACT OF THE DISCLOSURE        A carbon monoxide detecting apparatus is provided which is substantially inaffected by other coexisting gases in the gas atmosphere being sampled.  The present invention includes a first carbon monoxide detecting element, a second carbon monoxide detecting element, and a comparing means.  The first carbon monoxide detecting element is responsive to carbon monoxide gas and produces a stepwise change in a first film current over a first preselected range of carbon monoxide gas concentration.  The second carbon monoxide detecting element is responsive to carbon monoxide gas and produces a stepwise change in a second film current over a second preselected range of carbon monoxide gas.  The comparing means is responsive to the first and second film currents and provides an output difference signal .DELTA.E.  The amplitude of the output difference signal .DELTA.E is in accordance with the absolute value difference between the first film current and the second film current. The two preselected ranges of carbon monoxide gas concentration can be achieved by appropriately altering the structure of the respective carbon monoxide detecting element and/or by making the substrate temperatures of the two carbon monoxide detecting elements different.

Abstract: TITLE:    DRILL PIPE WEAR BELT ASSEMBLY Abstract of Disclosure:           A steel wear belt having a prepared inner surface with an inner diameter large enough to pass over the weld upset on one end of a drill pipe tube but too small to pass over the tool joints is installed about the pipe over a prepared outer peripheral surface thereof.  Preferably the belt outer diameter is equal to or less than that of the tool joints.  The belt is installed prior to one or both tool joints being welded to the tube.  The belt is secured to the tube by a mounting layer of high polymer material, e.g. plastics or elastomer, preferably self bonding and thermo-set, between the prepared surfaces.  The mounting layer may have a thickness in the rage of 1/16 to 1/4 inch and an elastic modulus of not over 5% of that of steel, and an elastic shear strength of, e.g. 500 to 3000 psi, and be stable up to 250 to 300 deg. F.  The thickness of the mount-ing and its physical properties prevent stress concentration in the pipe due to mere attachment of the wear belt and due to restraint on pipe flexure imposed by the wear belt and prevent electrolytic corrosion between the pipe and wear belt.  The pipe is plastic coated internally from tool joint to tool joint.  The internal coating and the wear belt mounting are preferably cured simultaneously and may both be made of phenolic or epoxy, or preferably, phenolic-epoxy synthetic resin; otherwise an elastomer would be preferred for the belt mounting.
