Rapid and precise analysis for calcium in blood serum
Differential absorption spectrophotometric technique, using murexide, gives a highly precise analysis of calcium in volumes of blood serum as small as 0.01 ml. The method of additions and proper timing allows compensation to be made for fading, variation in type of serum or plasma, and aging of the specimen.

Precise gimballing mechanism
Prototype support mechanisms allow precise and repeatable gimballing of engines with a minimum of lost motion and backlash. It also minimizes the use of gears and reduces lubrication requirements for long time space operations of several years duration.

Precision mounting for instrument optical elements provided by polyimide bonding
Epoxy resin-coated polyimide plastic is used for bonding materials with different thermal coefficients in applications requiring precision mounting, especially where vibrations, temperature extremes, and low pressures are encountered. Low vapor pressure of the bonding material precludes outgassing problems.

Magnetomotive forming for precision sizing and joining of large-diameter tubes
Portable electromagnetic coil enables high precision expansion or constriction and joining of large diameter metal tubes. A nonconducting mandrel or forming die is used on the side of the tubes wall opposite the coil. The coil is insulated from the tube by a thin plastic sleeve.

Manganese-56 coincidence-counting facility precisely measures neutron-source strength
Precise measurement of neutron-source strength is provided by a manganese 56 coincidence-counting facility using the manganese-bath technique. This facility combines nuclear instrumentation with coincidence-counting techniques to handle a wide variety of radioisotope-counting requirements.
De Volpi, A.↗
Precisely repeatable rotary mechanism
Precision-finished lead screw and a fitted mating nut member produce a linear translatory motion. This motion is transformed to a rotary movement of a pivotal platform member. The transformation is achieved by coupling the nut member and the platform member through a pair of opposed, taut, flex bands.
