Abstract: Abstract A method for determining an index of binding pro-teins in a serum sample comprising the steps of:  1.  Forming a mixture of a) the serum sample, having ligand binding sites, b) a quantity (usually a trace amount) of radioactive ligand and c) an amount of non-radioactive ligand such that the total amount of ligand (radioactive and non-radioactive) is in excess of the ligand binding sites available in the serum sample; 2.  Contacting the mixture with a quantity of a binder having a preferential affinity for the ligand; and 3.  There-after determining the distribution of the radioactive ligand such as by measuring the radioactivity of the binder.       The method is particularly applicable for determining thyroxine binding protein content in serum.  The method is also applicable to determine an index of serum free thyroxine as determined by the ratio of the con-centration of thyroxine to the concentration of thyroxine binding proteins.

Abstract: ABSTRACT OF THE DISCLOSURE      Large diameter legume starch granules including starches derived from yellow field pea, Pisum sativum (var) and faba bean, Vicia faba L. (Leguminosae) which have been treated to remove protein and fiber, and to improve color are used to replace scarce arrowroot starch granules as a protective stilt material in micro-encapsulated coatings, including carbonless copy paper.  The "stilt" material is used to prevent premature rupture of the microcapsules and early release of the microencapsulated materials. It has been discovered that the natural granule size, and other granule properties of the yellow field pea and faba bean starches are ideally suited to replace arrowroot starch granules as a protective material when the naturally occurring protein and fiber have been removed, and the color improved.      In certain coating processes in which the temperature at the coated surface exceeds the normal pasting temperature of these starch granules, the pasting temperature of the granules can be raised by a crosslinking agent, such as epichlorohydrin, phosphorus oxychloride, sodium trimetaphosphate, acrolein, or urea-formaldhyde can be used.  Under high alkaline conditions, using phosphorus oxychloride in a stepwise reaction procedure, it is possible to increase the pasting temperature of the starch granules by more than 25°F.      These fiber and protein free, large diameter legume starch particles may also be used for other purposes, such as for anti-offset powders in lithography, either with or without crosslinking or other derivatization to further improve chemical and physical properties.  These starches are also useful as absorbable dusting powders.  The large granule starches derived from most varieties of peas and beans can be used in the same manner.

Abstract: A TRANSPONDER FOR AN AUTOMATIC  VEHICLE IDENTIFICATION SYSTEM                Abstract of the Disclosure This disclosure relates to an inductively powered type of electronic transponder for identifying a moving object passing an interrogation area.  The transponder includes a tuned inductive-capacitive pick-up circuit for receiving interrogating signals.  The picked up interrogating signals are rectified to produce d.c. operating power and are applied to a frequency divider for producing a frequency related transmission signal and clock data rate pulse.  A latching circuit enables a shift register so that the clock pulses ser-ially shift out binary encoded data from the shift register.      The encoded data is fed to a logic network which is coupled to a balanced switching amplifier for phase modulating the transmission signal for propagation into the interrogation area.
