Abstract: A process for the preparation of 3,5,6-trichloropyridin-2-ol from trichloroacetyl chloride and acrylonitrile is improved by separately conducting the individual addition, cyclization and aromatization steps. By separating these steps, water and HCl, which are by-products of the latter steps, can be precluded from interfering with the earlier steps. The individual process steps have also been improved.

Abstract: Abstract of the Disclosure A probe for providing noise measurements of an electrical circuit includes at least one loop of wire connected to a plurality of conductors. The loop interconnects one or more signal-carrying ones of the conductors to one or more of the conductors carrying ground and has a portion which is substantially straight or is deformable to follow the path of a conductor in the electrical circuit. Preferably, the loop is formed so that this straight portion terminates in a right angle bend at each end. This loop serves as an inductive pickup which avoids the need for contact of the probe to the circuit under test and, thereby, provides more accurate noise measurements.

Abstract: A process for separating emulsified, suspended and separate oil as well as other contaminants from the water phase of a compressed air system condensate comprises the steps of discharging air and condensate from a compressed air system into a water filled separation tank where air is separated from the condensate.  Some of the contaminants heavier than water are allowed to settle to the bottom of the separation tank while lighter oil contaminants are allowed to float to the surface where they are removed.          Water and the remaining contaminants which did not flow to the surface or settle to the bottom of the tank are drained away until a given amount of liquid mass has been accumulated.  Pressure applied to the liquid mass forces the mass into and through an underwater coalescing media.          Such action causes substantially all of the remaining oil constituents to coalesce and thereby form a floating oil phase while other contaminants are retained by the coalescing media.  The floating oil phase is removed and the remaining water is relatively pure.
