Abstract: ABSTRACT           A signal discriminator is disclosed for use with a listening array, for detecting the presence of a signal coming from a predetermined direction against a background of noise.          Signals from the receivers in the array applied to a unanimity circuit which detects the occurrence of unanimity, which is when all the signals are of the same sense.  When a coherent signal is present the probability of unanimity occurring is greater than when it is absent.  A computer is included which receives signals from the unanimity circuit and analyses them, preferably using sequential sampling technique, to determine whether or not unamity is occurring with a probability high enough to indicate the presence of a coherent signal, and indicates the presence or absence of a signal accordingly.

Abstract: ABSTRACT OF THE DISCLOSURE     In a process for solidifying molten materials by pouring onto a substrate and cooling, silicone fluids or kerosene are incorporated in the solidifying melt to promote the formation of amorphous material and provide increased hardness on aging.  Undesired cryst-allinity is also avoided by first forming a solidified skin on the melt surface by carefully controlled air cooling or dusting with powdered material before more vigorous cooling by air or water directed against the solidified skin.  When using an endless belt as substrate, the plain surface may be modified by superposing a skeleton framework to form tablet orbar moulds.  The process is particularly applied to the solidification of molten sulphur.

Abstract: ABSTRACT      Pulsed droplet ejecting systems are described of the type in which a conduit conducts liquid from a reservoir to an orifice.  The liquid is under zero or slightly negative pressure, and surface tension in the orifice prevents flow in the absence of other forces.  An electro-acoustic transducer is coupled to the liquid and when an electric pulse is applied a pressure wave travels in the liquid to the orifice causing ejection of a drop-let of liquid.  Systems of this type work well only when free of entrapped air, a condition difficult to achieve in prior art designs.  Means are disclosed for readily and reliably filling such system without entrap-ment of air pockets.  A second conduit is permanently or temporarily joined to the first conduit adjacent to or in place of the orifice, and means are provided for temporarily causing rapid flow of liquid from the reservoir through the first conduit into and through the second conduit.  The conduits have sufficiently large cross sections so that the flow can be fast enough to sweep out all air pockets that might otherwise remain if flow during filling the system were through a single conduit and out a typical small orifice.

Abstract: ABSTRACT OF THE DISCLOSURE        A control system for use with a braking mechanism which employs an energy-storing spring and  an electric rotating servomotor is disclosed.  The system operates employing a direct or indirect measurement of the stored braking force. When an indirect approach is used, a pair of selsyns supply a measured rotational parameter which is related to braking force. After suitable processing, which includes the use of a discriminator and counter, a parameter relating to the stored braking force is compared with a desired value at a summing point to provide a correction  parameter for braking control. When direct braking force measurement is used, the measured braking force is supplied directly to a summing point for comparison with a desired value.  In both direct and indirect measurement, a differentiator is included which supplies the derivative of the measured value to the summing point. The output of the summing point is a correction parameter which operates triggering devices for brake actuation and release.  These devices in turn control the motor and a brake control winding in the braking mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE            An integral device for controlling the rate of throttle closure and for preventing after run of an internal combustion engine is provided which utilizes a pair of dia-phragm assemblies for accomplishing both functional opera-tions.  The device includes a dash pot stem having an axial opening through it.  The opening is operatively connected to a source of engine vacuum.  A diaphragm housing defining a cham-ber has a pair of diaphragm assemblies positioned in it.  A first diaphragm assembly is mounted to the dash pot stem.          The second diaphragm assembly is movably mounted on the dash pot stem and includes a shaft extending through the housing, The shaft is engagable with suitable linkage means operatively connected to a throttle valve of a carburetor for the engine.          Upon engine start, the application of engine vacuum to a first side of the first diaphragm operates on the diaphragm and housing so that, in effect, the housing moves in a first direc-tion, positioning the shaft at its curb idle position.  The second diaphragm assembly extends the shaft as the engine begins to increase speed from curb idle, and acts to bring the car-buretor slowly to its curb idle setting upon throttle release from the running condition.  Removal of engine vacuum enables the first diaphragm to operate in conjunction with the housing to return the housing to its initial position, permitting the throttle to close below its curb idle setting.

Abstract: ABSTRACT OF THE DISCLOSURE           A single pressure sulfur hexafluoride circuit interrupter is contained in a bottle or elongated, cylindrical housing filled with gas under moderate pressure.  The bottle contains arcing and main contacts arranged generally along the axis of the bottle and arranged to separate from one another in the vicinity of a pair of spaced, conductive rings fixed relative to one another, and which serve as arc runners.  Each of the rings is connected in series with a respective coil which is wound on the axis of its respective ring and which encircles the cooperating contact and conductors therefor.  The coils and the conductive rings create a magnetic field which spins an arc drawn between the spaced short-circuited rings through the sulfur hexafluoride gas, thereby to extinguish the arc.  Each short-circuited ring and its respective coil are fixed relative to one another and are contained within a common insulation body in order to withstand the high electrodynamic forces created between the rings and coils during high current interruption.  A small, low capacity puffer cylinder is connected to one of the moving contacts in order to produce at least a limited amount of gas motion through the arc space between the open contacts and the fixed rings when the contacts separate.  The arcing contacts are arranged to have a blow-off path directed to cause an arc drawn between the contacts to transfer to the spaced conductive rings.          In one embodiment of the invention, only a single coil is used to produce a magnetic field for spinning the arc between the spaced rings.  The interrupter structure is useful in connection with a vacuum dielectric medium.

Abstract: ABSTRACT OF THE DISCLOSURE           A device for measuring the statistical distribution within a discrete range of a measured continuous variable.  A conventional type meter which employs a scaling amplifier in series with weighted filters, a true RMS detector and time averager is used to detect the variable level and convert it to a analogue voltage of magnitude proportional to the magnitude of the variable at any given instant.  The voltage signal is then passed through a scaling amplifier to an analogue to digital converter.  The converter is controlled by a timer with an adjustable rate in such a way that the converter output is pulsed.  Each level of the digital output is connected to a counter. Since each level corresponds to a discrete range of magnitudes of the variable, the percent time within a giver discrete range can be calculated from the ratio of the pulses counted at a given level to the total number of samples taken.
