Abstract: ABSTRACT:     A method of determining the concentration of the free portion of a ligand present in a biological fluid which also contains the ligand bound to one or more natural binders involves the single step of mixing a sample of the fluid with a labelled derivative of the ligand and a specific binder for the ligand, incubating the mixture, and determining the proportion of the labelled derivative of the ligand bound to the specific binder.  The labelled derivative of the ligand is chosen to bind strongly to the added specific binder, but to bind not at all, or much more weakly than does the ligand, to the natural binders in the biological fluid.  A small amount of the labelled derivative can be used and the binding equilibrium of the ligand id not appreciably perturbed.   Ligands include thyroxine, tri-iodotbyroxine and control.

Abstract: Abstract of the Disclosure A torsional vibrator damper of the type having a hub and an inertia ring, the hub and inertia ring coupled to each other by an elastomer member.  The hub is adapted to be coupled to the crankshaft of an engine.  The inertia ring is formed of two axially spaced ring parts with each ring part having at least one annular groove.  A ring locking element is provided in the form of a radially extending disc carrying at least one generally axially extending locking key, and the axially outer-most ends of the locking key are received in, respectively, the ring part annular grooves.  The axially outermost ends of the locking key are each deformed to each define a tang which extends at least partially in a radial direction.  The radially extending disc is under axial compression and thus exerts an axially extend-ing force against the two ring parts to urge them apart.  The tangs of the locking key contact portions of the annular grooves to resist the disc axially directed force.  The annular grooves are trapezoidal in longitudinal cross-section.  The longest parallel side of each trapezoid is farthest from the junction of the two ring parts.

Abstract: ABSTRACT The filter arrangement for an X-ray apparatus contains an X-ray source for emitting a diverging beam of X-rays and a filter plate positioned in the beam of X-rays.  The beam is symmetrical with respect to a center beam axis. The filter plate which serves for attenuation of the X-rays before they impinge on a target is mounted on a pivoting axis.  The pivoting axis is preferably arranged remote from and transverse to the center beam axis.  By pivoting the filter plate about the pivoting axis into a selected position, a selected radiation profile can be obtained on the target.  The rotatable filter plate can thus replace a plurality of wedge filters.

Abstract: ABSTRACT        On-line locomotives of a consist are determined by a control system that conserves fuel by throttling back trailing locomotives and operating the remainder at the most efficient throttle position.  The engineer operates a control unit in the lead locomotive to command control units in trailing locomotives, depressing a "subtract power" button, to throttle back one trailing locomotive and "add power" button to return a trailing locomotive on line by advancing its throttle to the most efficient position.  A cutout control signal from the lead locomotive, transmitted to trailing units in order (front to rear) by one spare trainline wire, has voltage levels that progressively decrease or increase in response to the commands.  These levels are decoded by trailing units and throttles are set accordingly.          The trailing units lower these levels by a fixed amount as the control signal is conducted by the trainline wire rearwardly from each trailing unit to the next.  Accordingly locomotives are throttled back from the rear and returned on line from the front.          An interrogation signal is periodically transmitted, and the trailing units respond sequentially, reporting the status of the locomotives.  Once a report indicates that a trailing locomotive has been cut out or put on line, the lead unit ceases the progressive change in the control signal voltage levels.  The lead unit also has a display to indicate the number of units on line.     The control signal also has an identifier pulse portion detectable by the trailing units to effect cutout of a locomotive.
