Abstract: Abstract Disclosed is a high resolution frequency measuring system which uses a frequency counter for a coarse reading and a frequency to voltage converter for a vernier reading, which readings are combined.  Two types of converters are disclosed.          One embodiment comprises an input terminal for receiving an input signal frequency and a pulse shaper for converting the input signal to a first train of pulses.  The pulses are applied to a delay means to produce a second train of pulses delayed with respect to the first train of pulses and the first and second trains of pulses are applied to first and second inputs of a phase detector, e.g. a flip-flop.  In another embodiment, delayed and undelayed versions of the input signal are fed to separate pulse shapers and then to the inputs of the phase detector.  The phase detector has an output connected to operate a switch between two voltage levels to produce a third train of pulses having a duty ratio depending on the phase difference between the first and second trains of pulses.  The third train of pulses is time averaged to produce an output voltage, the output voltage being proportional to the phase difference between the first and second trains of pulses and varying with changes in the frequency of the input signal.          An analog to digital converter converts the output voltage to a digital reading for combining with the output of the frequency counter.  The invention provides a unique, fast frequency measuring system allowing high resolution, not obtainable with a counter.

Abstract: Case 3794 A ONE-PIECE TORQUE TRANSMITTING DEVICE     ABSTRACT     A one-piece torque transmitting device includes a U-shaped clip which is detachably secured to the swaged end of a cylindrical shaft.  The clip is secured to the swaged end of the shaft by the inherent resiliency of the spring-like material cooperating with inwardly struck burred teeth which bite into the material of the shaft when the clip is positioned thereon.  The clip has a slot in the bight portion to receive the end of the swaged end, a plurality of inwardly projecting detents, and outwardly extending recesses cooperating to limit lateral shifting of the clip relative to the longitudinal axis of the shaft.

Abstract: ABSTRACT OF THE DISCLOSURE          "COMPUTER-CONTROLLED, PORTABLE PULSED NMR INSTRUMENT AND METHOD OF USE WHEREIN THE TIMES OF RF INTERROGATION  ARE DISTRIBUTED OVER AT LEAST A CYCLE AT THE NUCLEAR          MAGNETIZATION PRECESSIONAL FREQUENCY" In accordance with the present invention, fluid-flow properties of a rock sample based on NMR response of the hydrogen nuclei of interstitial fluids within the pore space of such sample, can be swiftly and accurately achieved using a computer-controlled, portable NMR instrument.  The inherent instrument inadequacy of a DC field inhomogeneity is controllably augmented by an adaptively generated gating code (provided via a computer-controller in feedback relationship with an oscillator-master clock controlling a transmitter-pulser) to ensure that the nuclear magnetization precessional frequency is not a multiple of the RF interrogation frequency.  Result:  Even though the instrument is placed at field sites away from the usual processing center, quick analysis of rock samples as during the drilling of a well, still results.

Abstract: ABSTRACT OF DISCLOSURE     Process for applying a protective coating to a metal substrate which provides a thermal barrier and a barrier against oxidation of the substrate.  The coating material is a mixture of two metals M1 and M2, e.g., cerium (M1) and cobalt (M2), one of which when exposed to an atmosphere containing a low partial pressure of oxygen and at a high temperature forms a stable oxide, the other of which does not form a stable oxide under such conditions.          A coating consisting of such a metal alloy or mixture is subjected to such conditions to produce an outer oxide layer of metal M1 and an inner metal layer of M2 alloyed with one or more components of the substrate.  The oxide layer provides thermal and oxidation protection and the inner layer bonds the coating to the substrate.
