Abstract: ABSTRACT OF THE DISCLOSURE     The method of this invention is characterized by the use of hydrolyzed cross-linked polyacrylamide particles to which have been bonded, by means of covalent bonds, antibodies against the thyroid hormone to be determined.          The particles selected are of a size which forms a stable hydrophyllic suspension.  In the preferred embodiment a measured quantity of unextracted human serum is mixed together with a blocking agent in an amount sufficient to displace the thyroid hormone to be measured from thyroxine binding globulin (TBG), a radioactively labeled thyroid hormone of the type to be measured, and the antibody-pol-yacrylamide complex.  The hormone to be measured is dis-placed by the blocking agent followed by the competitive binding of the labeled and unlabeled hormone to the anti-body-polyacrylamide particles.  The particles are readily separated from the sample liquid and the radioactivity of the particle material and/or in the liquid is determined.    Particles containing Alcian yellow or blue dye facilitate practice of the method.

Abstract: Abstract of the Disclosure Disclosed herein is a drill bit for earth boring that achieves pressure compensation or equalization of pres-sure across  the seal separating the lubricant inside the bit from the drilling mud on the exterior of the bit by providing sufficient displacement of the seal to accommodate changes in lubricant volume caused by temperature and pressure changes encountered in drilling.  By minimizing the volume of lubricant in the system, seal displacement may be mini-mized to produce pressure equalization across the seal with-out need for additional pressure equalization.  Therefore, the lubrication system may be simplified and its reliability increased.

Abstract: ABSTRACT           A snap-on, wire pay-off cap assembly to facilitate the un-reeling of wire past one end of a wire filled spool, compris-ing a wheel adapted to be engaged by the wire being de-reeled, a circular brush disposed broadside to the wheel and having tines extending past the wheel periphery, a support member rotatably mounting the wheel and fixedly mounting the brush in their respective operative positions, and an operable clamp carried by the support member and adapted to engage the rim of one of the spool flanges for holding the cap assembly captive at one end of the spool.  The clamp includes several radially extending arms which have hooks at their ends, to latch over the rim  of the flange.  Spring means associated with one of the arms biases it in a radially inward direction to thereby maintain the engagement of the hooks and the rim.  The arrange-ment is such that the operator can grasp the assembly either by the wheel or else by one of the arms, latch the spring-loaded arm over the rim to extend the spring and then latch the remaining arms over other circumferentially spaced areas of the rim.  The advantage of the present construction is that the quick  installation and removal of the cap assembly enables high speed and trouble-free operation to be realized.

Abstract: LEVEL SENSITIVE EMBEDDED ARRAY LOGIC SYSTEM Abstract A generalized and modular logic system is described for all arithmetic/logical units and their associated control storage and any other arrays.  The logic system is partitioned into sections formed of combinational logic networks, storage circuitry, and arrays.  The storage circuitry is sequential in operation and employs clocked dc latches.  Two or more synchronous, non-overlapping, independent system clock trains are used to control the latches.  The array is a rectangular array of storage element, M x N where, M is the number of words in the array and N is the number of bits in each word.  The array may be read only, or it may be a read/write array.  The array may be a programmable logic array (PLA).  A single- sided delay dependency is imparted to the system.  The feedback connections from the respective latch circuitry are made through combinational logic or an array to other latch circuitry.  The clocking of the latches and of the array, if any, are such that the network may be operated in a race free mode.  With each latch, there is provided addi-tional circuitry so that each latch acts as one position of a shift register having input/output and shift controls that are independent of the system clocks and the system input/outputs.  All of the shift register latches are coupled together into a single shift register. The logic between the latch inputs and the array inputs has the property that a 1 to 1 correspondences can exist between array inputs and the latch inputs.  Furthermore, all of the array outputs are uniquely detectable at the latch or primary outputs.
