Abstract: ABSTRACT OF THE DISCLOSURE      A machine for manufacturing triaxial fabrics, primarily of the type disclosed and claimed in United States Reissue Patent Number 28155 of Norris F. Dow, reissued September 10, 1974, comprises a vertically oriented warp yarn supply means based upon a horizontally disposed rotating creel, on which is preferably mounted a plurality of beams each supplying a plurality of warp yarn ends.  Guide holders travelling on a cam-shaped track compensate for warp yarn path length changes so as to maintain path lengths from creel to weaving means relatively constant independent of angular position of an individual warp yarn in the course of the weaving process.  Preferably, a multiplicity of such guides are combined on a single trolley carrier several of which are mounted at spaced intervals on the cam-shaped track, the movement of which is co-ordinated with the rotational move-ment of the warp yarn supply creel.  Tension is maintained in the warp yarn supply by a multiplicity of individual roller guides mounted on spring arms which bend slightly to maintain tension in each warp yarn as the weaving shed is made and unmade.

Abstract: A POWERING SCHEME FOR JOSEPHSON LOGIC CIRCUITS             WHICH ELIMINATES DISTURB SIGNALS                  Abstract of the Disclosure A Josephson junction terminated line logic powering scheme is disclosed wherein a logic gate and a regulating gate are utilized in at least a single logic circuit to provide a constant voltage to the logic circuit.  The circuit comprises a terminated line logic gate with its associated sense gate and a regulating gate in series with the logic gate.  When the logic gate is switched to the voltage state, it sends a disturb signal up and down the line which carries the gate current to the logic devices.  A regulator gate which has already been biased to the voltage state is reset to the zero voltage state by the disturb signal.  The resetting of the regulator gate sends out a disturb signal which cancels the original disturb signal with a small delay.  The result of the combination of the disturbance generated by the logic gate and the regulating gate is an extremely narrow pulse with a maxi-mum width equal to the round trip delay between the adjacent gates having an amplitude of 1-1min.  In the steady state, the total voltage drop across the supply line remains constant before and after logic opera-tions.  Thus, d.c. regulation problems are eliminated.  Using this approach for powering logic gates, it is possible to reset the logic gates by applying a control pulse to the regulating gates so that all of these gates which are in the zero voltage state will be switched to the voltage state.  The disturbance resulting from this switching action resets the adjacent logic gate in the same manner as the logic.

Abstract: WELL SYSTEM               Abstract of the Disclosure A well system comprising a pump having an inlet and an outlet and a combined pressure regulating valve and pressure tank.  The combined pressure regulating valve and pressure tank comprises a hollow container having a diaphragm therein overlying an inlet connected to the outlet of the pump and an outlet connected to the system.  The diaphragm is urged by a charge of gas in the container to normally seal the inlet and outlet to said chamber in the absence of fluid pressure from the pump sufficient to move the diaphragm away from the inlet and outlet.  Thus, the combined pressure regulator valve and pressure tank functions to insure that the flow from the outlet is substantially at a predetermined pressure and that when the pressure falls below a predetermined amount, the diaphragm seals against said inlet and the outlet to said chamber and maintains water in the outlet of the pump sufficient to maintain a prime on the pump and prevent the pump from running dry.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE     A device for detecting a persisting electrical overload in an electrical system includes a sensor for monitoring the current in the electrical system and for generating an electrical signal whose magnitude represents the instantaneous absolute value of the current.  A thres-hold control generates an output signal of predetermined value and develops, in cooperation with the sensor, an electrical signal whose magnitude represents the amount by which the magnitude of the absolute value signal exceeds the predetermined value.  An integrator integrates the aforementioned electrical signal to generate an output whose magnitude includes a component representative of the product of the electrical signal and a time-increasing value that represents the duration that an overload has persisted.  A comparator continuously compares the magnitude of the integrater output signal with a second preselected value and generates an indicative output whenever the inte-grator output signal exceeds the second preselected value.
