Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure relates to a monitoring system and method for determining the magnitude of the equiva-lent voltage source impedance and the magnitude of the equivalent voltage source voltage on a telephone line and switching network of a telephone system. The monitoring system measures the Thevenin source voltage and source impedance to ground on the line by applying two independant voltage conditions to the line and senses the resulting steady state voltages thereby produced in a sensing resistor.  The magnitudes of the sensed steady state voltage are thereafter utilized for obtaining the Thevenin source voltage and source impedance magnitudes.

Abstract: ABSTRACT     A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member.  Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism may be provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies.  Means are provided between the roller and cam to limit the amount of torque which can be developed by the wedging action of the cam and roller mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of treating fibrous material such as textile products, e.g. garments or the like, which may be compressible, so as to permit the product to have improved wrinkle resistance particularly when such products are vacuum packaged or otherwise, wrinkling would occur.  The method involves treating the material to reduce the segment mobility level of the fibrous material to a point below that prior to treatment and to lower the relative regain level of the material.  The method also involves lowering, for fibrous materials, regain levels of such materials to preferably below .27.  In the methods, the segment mobility and regain levels are preferably stabilized under a stabilization step before packaging.

Abstract: METHOD FOR FORMING GLASS CONTAINERS            ABSTRACT OF THE DISCLOSURE          Method for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities,  The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity.  Vacuum is applied to the neck area of the mold to form the finish portion of the container.          A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is the  opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the pari-son,  The parison transfer is carried out by the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the up-right position at the blow mold or to help sustain the parison against collapse during invert,  The ability to apply puffing air to the parison during transfer is 2 significant step in the forming process.

Abstract: ABSTRACT OF THE DISCLOSURE     Metering kWh is an electrical system is accomplished by generating pairs of analog signals representing current and voltage variables.  A comparator compares an analog signal which is proportional to the voltage in the system with a relatively high frequency triangular waveform.  The Output of the comparator, which is a pulse-width modulated signal having a pulse duration proportional to the ampli-tude of the voltage in the system, is multiplied by a signal which is proportional to the current in the system.          The output of the multiplier is integrated to thereby provide a signal which is proportional to the energy consumed in the system.  The output of the integrator is converted to a pulse train having each pulse proportional to the kilowatt hours consumed in the electrical system.          A mechanical accumulation and display means records the total energy consumed and is driven in response to the output of the analog-to-pulse rate converter.  The pulse output of the converter closes a switch which couples a relatively large amount of current to a motor winding which advances the mechanical display.  Power for the active elements in the system, including the drive for the mechanical display, is derived from the system being measured by means of an internally provided power supply.          Error correction is provided by means of a switching means which reverses the phase of the triangular wave-form and the first analog signal by reversing the con-nections of these signals to the comparator.
