Abstract: INDUCTIVE LOAD CURRENT MEASURING CIRCUIT          Abstract of the Disclosure A circuit for generating a signal proportional to the average current of an inductive load supplied from a supply of intermittent electrical power and having a free-wheeling path through which load current flows during periods in which the load is not connected to the power supply, includes means to provide a first signal which is a function of the current in the free-wheeling path and second means to provide a second signal which is a function of the supply-load current.  By appropriately combining the two signals an output proportional to the average load current is obtained.          The output signal can be utilized for control functions such as controlling the operation of switching devices which, in turn, control the application of electrical power to a d.c. motor.

Abstract: ABSTRACT OF THE DISCLOSURE        A plurality of jet gun bars are spaced apart along the path of travel of a textile material and responsive to pattern data to form patterns on the material.  Each gun bar stores and supplies different color dyestuff to color the material.  A computer, on each periodic request, supplies pattern data to a predetermined number of gun bars, there-by providing dyestuff to different pattern lines for each request.  During a change from printing one pattern to printing another different pattern, for each such request the computer provides data for the other pattern to a first predetermined number of gun bars and data for the one pattern to a second predetermined number of gun bars subsequent to the first number, thereby simultaneously completing the printing of the one pattern and starting the printing of the other pattern.

Abstract: ABSTRACT OF THE DISCLOSURE            A quick connect coupling is disclosed providing a body assembly having a tube end receiving passage proportioned to closely fit the forward end of a tube.  A seal is located in the body assembly to provide a fluid tight joint between the end of the tube and the body assembly.  The body assembly also includes a lock ring retaining groove within a nut with an expandable lock ring positioned therein.  Mounted on the tube at a location spaced from the end thereof is a locking sleeve which is crimped inwardly toward a tubular insert to lock the locking sleeve in position.  The forward end of the locking sleeve is formed with a camming ramp which extends toward a lock ring groove.  Assembly of the coupling requires the mere axial movement of the tube end assembly into the body assembly until the seal engages the outer surface of the tube and the lock ring bridges between the nut groove and the lock sleeve groove to permanently connect the tube end and the nut.

Abstract: Abstract of the Disclosure A method and circuitry are disclosed which allow the operation of carbon microphones in telephone sets at low levels of average current.  The microphone is connected to a pulse-generating circuit which energizes the microphone with pulses of current that effectively sample the incident acoustic signal at a superaudible rate.  The level of each current pulse is chosen so that the microphone performs at the high signal-to-noise ratio associated with high current levels and the duty cycle is chosen to match the low average value of available current.  The audio signal is recovered by demodulating the resulting PAM (voltage) output signals using a low pass filter.  The level of the recovered audio signals is then amplified to the level required by the telephone transmission line.  The sampling approach, using the carbon microphone as the sampling element, extends the utility of the carbon microphone to operation at low average current levels which hitherto were unusable because of low signal-to-noise ratio.  This method may also permit a uniform reduction in current levels on all the lines of an associated telephone central office thereby reducing total power consumption and allowing the use of higher resistance, fine gauge transmission loops.                             - i -

Abstract: METHOD AND APPARATUS FOR RUNNING AND RETRIEVING LOGGING INSTRUMENTS IN HIGHLY DEVIATED WELL BORES            Abstract of the Disclosure   The system consists of means for running a logging instrument connected to a long rigid extension on a logging cable through open-ended drill pipe.  A head on the upper end of the extensions conforms sufficiently close to the inside diameter of the drill pipe that pump pressure down the drill pipe develops thrust across the head to push the extension and logging instrument down the well bore.  A catcher sub at the lower end of the drill pipe prevents the uppermost portion of the extension from being pumped out the bottom of the drill pipe.  As the extension and logging instrument are pulled back into the drill pipe by the logging cable, well bore measurements are made and recorded over the interval below the bottom of the drill pipe.  The extension consists of a number of sections of tubing that are joined together on top of the instrument as the instrument is lowered into the drill pipe prior to the logging cable being connected to the well logging instrument.  As soon as the last section of the tubing has been added, the well logging cable, having an electrical probe member attached to its lower end and having weighting means to cause the probe to lower itself through the tubing, is fed down through the tubing and into a circulation and electrical connection sub connected to the well logging instrument itself.  After the connection is made, the tubing and well logging instrument are supported by the well logging cable and together they are lowered further through the drill pipe and out through the end of the drill pipe until a cable tension adapter sub reaches a catcher sub at the end of the drill pipe.  During logging, the logging cable is hoisted in the upward direction to log the formations surrounding the well bore beneath the lower end of the drill pipe.                             -1a-

Abstract: S P E C I F I C A T I O N                 Inventor:  William F. Gillen, Jr.                 Title:  "Precast Concrete Threaded Pilings"          Abstract of the Disclosure A reinforced concrete threaded pile provides a generally conically shaped tapered concrete pile member which is provided with a metallic   reinforcement core for carrying the torsional and tensile forces created in the pile during its insertion.  A metallic head is provided at, for example, the upper portion of the pile,which provides a point for the connection of a sufficient torsional driving force thereto for insertion of the pile.  The head member can be metallic, and is substantially integrally connected to the reinforcement core, so that the torsional forces can be developed through the head and the reinforcement core such that torsional and tensile forces are not carried by the concrete to a degree which would cause a failure of the concrete by cracking.  The concrete body is provided with an outer surface of spiral threads which has a relatively minor thread pitch that provides for relatively easy insertion of the pile into the desired soil medium and is mechanically compatible therewith.  If desired, reinforcement can be provided in the threads.  The threads are equally spaced, and a female "soil socket" is formed upon insertion of the pile into the earth, the spiral tapered pile gradually expanding and compacting the surrounding soil as the equally spaced threads push the pile downward.
