Abstract: A FLOATING DC CURRENT SOURCE FOR A SUBSCRIBER LOOP CIRCUIT by CONSTANTINE VICTOR SKIDANENKO and GREGOR DONALD McGIBBON      ABSTRACT OF THE DISCLOSURE        Under an off-hook condition a pulse width control circuit is periodically turned on by narrow pulses from a clock source. This initiates current flow from a primary dc source via the single primary winding of a transformer, and through power transistors connected in a Darlington configuration.  A ramp voltage is developed across an emit-ter resistor of one of said power transistors and this voltage is feed-back to said pulse width control circuit.  When the ramp voltage reaches a predetermined value, the pulse width control circuit turns off the power transistors and the energy stored in the transformer is transfer-red by the collapsing magnetic field into alternating current in the secondary winding.  This alternating current is rectified and filtered to provide loop current to the telephone subscriber loop.  The voltage reflected from the secondary to the primary is stored in a peak detec-tor circuit which operates to control the length of time during which the ramp voltage builds to its predetermined amplitude.  The magnitude of the reflected voltage is a function of the loop resistance.  Thus, a controlled loop curent is provided which is dependent upon the loop resistance.  When the loop resistance reaches a predetermined value, a breakdown diode in the output of the peak detector allows  current to flow in an "idle power shutdown circuit" which interrupts the clock pulse input to the pulse width control circuit.  This permits a reduction in power during the on-hook state.

Abstract: Abstract of the Disclosure A fiber optic amplifier utilizes a crystal fiber of laser material to bidirectionally amplify light signals. This amplifier permits  the application of both pumping illumination and the signal to be amplified to the end of the crystal fiber to avoid the disadvantages inherent in side pumping this fiber.   End pumping is accomplished by taking advantage of the slow spontaneous fluorescence of the  laser  crystal  to  sequentially  apply  the  pumping illumination and then the signal to be amplified to the crystal.   This sequential application of signals is made possible through the use of a switchable coupler which allows light to be selectively coupled from either of a pair of input optical fibers to a single output optical fiber which is coupled to the crystal fiber.  The pumping illumination is initially supplied to the crystal fiber to invert the ions within the crystal.  Once these ions are inverted, the coupler is switched to permit the applica-tion of the signal to be amplified to the crystal, and the application   of  pumping   illumination   is   temporarily discontinued.  The  signal to  be  amplified  propagates through  the  crystal  to  stimulate  emission of  coherent light from the laser material resulting in amplification of  the  signal.    When  this  amplification  process  is complete, pumping illumination is again applied through the switch to the crystal fiber.

Abstract: FLOW-AMPLIFYING LIQUID-ATOMIZING NOZZLE     Abstract of the Disclosure A liquid-atomizing nozzle in which intermixing of air and liquid occurs externally of the nozzle and the primary air utilized for such intermixing is amplified by the entrainment of ambient secondary air.  Two versions of the nozzle are disclosed, each having a tubular body with a generally cylindrical section terminating in a conical nose section.  Air under pressure is discharged through radial openings in the cylindrical section and is redirected by a collar surrounding the cylindrical section to form a high velocity stream of air about and along the gradually-tapered outer surface of the nose section.  Such high velocity primary air, amplified by ambient secondary air, strips liquid from at least one opening in the nose section to produce an externally-developed air-liquid mixture.  In one version the liquid discharge opening is at the tip of the conical nose section; in another version a plurality of such openings are formed in the conical surface of that section.

Abstract: ABSTRACT             PROCESS AND APPARATUS FOR MAKING ROLLED WAFER CONES           In a process of making a rolled wafer cone from a baked flat wafer blank made from a sugar-containing wafer dough, the baked wafer blank is rolled to form a wafer cone in a winding mold (3) while the wafer blank is still in a soft, deformable state after the baking operation.  Thereafter the rolled wafer cone is permitted to harden.  In order to ensure the production of wafer cones having consistently exactly the same shape, it is proposed that the wafer cone which is unrestrained at least in part is shortened in the winding mold to a predetermined length while the wafer cone is adapted to be plastically deformed.  For this purpose the rolled wafer cone disposed in the winding mold is subjected to a plastic deformation only at one end or only at both ends. The process can be carried out by means of winding devices (5), which are mounted on a rotary frame (4, 6) and each of which comprises a conical winding core (8), which is secured to a winding shaft (7) that is displaceable relative to the rotary frame to move the conical winding into and out of the winding mold (3).  In that apparatus each winding device is provided with at least one sizing device (9), which is associated with the rim of the wafer cone and comprises at least one pressure-applying finger (12), which is adapted to be introduced between the winding mold and the winding core.

Abstract: Analog/Digital Converter Abstract of the Invention A digital integrator having a 16-bit output is followed by a first 12-bit digital/analog converter which is supplied with the output bits 1-11 and 16 of the integrator and which forms a first tracking loop with a first subtractor which forms a first dif-ference signal from the output signal, proportional to the input signal of the analog/digital converter, of a first amplifier and the output signal of the first digital/analog converter.  A tracking circuit generates tracking signals for the integrator on the basis of the difference signal.  To extend the dynamic range, a second 12-bit digital/analog converter is present which is supplied with bits 5-16 from the output of the integrator and which forms a second tracking loop with a second subtractor and a second amplifier, the gain factor of which is 1/16th of the gain factor of the first amplifier, to which loop a control logic switches over when the range which can be covered with the first digital/analog converter is exceeded.  Switch-ing back takes place at the next zero crossing, that is to say,  change of the most significant bit.  The digital/analog converter is particularly suitable for processing the output signal of a current or voltage converter.

Abstract: PROPELLER SPEED AND PHASE SENSOR               ABSTRACT OF THE DISCLOSURE          A speed and phase sensor for counterrotating aircraft propellers is described.  A toothed wheel is attached to each propeller, and the teeth trigger a sensor as they pass, producing a sequence of signals.          From the sequence of signals, the rotational speed of each propeller is computed, based on the time intervals between successive signals.  The speed can be computed several times during one revolution, thus giving speed information which is highly up-to-date.        Given that the spacing between teeth may not be uniform, the signals produced may be nonuniform in time.  Error coefficients are derived to correct for nonuniformities in the resulting signals, thus allowing accurate speed to be computed despite the spacing nonuniformities.        Phase can be viewed as the relative rotational position of one propeller with respect to the other, but measured at a fixed time.  The invention computes phase from the signals.
