Abstract: ABSTRACT OF THE DISCLOSURE A closed loop control system is presented which trims fuel flow to the turbine engines of a multi-engine aircraft in response to fan speed and turbine temperature measurements. The closed loop system is activated after the initial climb out phase of flight.  To engage -the automatic control system the pilot will first preset a not-to-exceed measured gas tempera-ture for the turbines and secondly, adjust the throttles to bring engine fan speeds within the pull-in range of the synchro-nizer.  This done, the pilot engages the closed loop control system which functions by having fan speed and turbine tempera-ture data signals transmitted to an electronic type master control unit.  Acting on the incoming signal data, the master control unit pulses throttle actuators,  There is a throttle actuator serially connected between each throttle lever and the fuel control valve associated therewith.  Each throttle actuator is capable of increasing and decreasing the effective preset value of a throttle by an amount just sufficient to maintain speed synchronization and temperature control of the associated engine during the cruise phases of flight,  The automatic system has limited authority and the pilot can override at any time by simply moving the throttle levers.

Abstract: ABSTRACT OF THE DISCLOSURE         In a rolling mill wherein hot rolled rod is directed along a downwardly curved path into a vertical laying head which forms the rod into a series of rings, a method of and apparatus for propelling the rod through the laying head.  The rod is passed between a pair of adjustable driven pinch rolls located in advance of the downwardly curved path.  An initial closing force is exerted on the pinch rolls to establish an initial parting prior to entry of a rod front end therebetween.          The initial parting is sized to produce at least some rod deformation while providing a driving relationship between the pinch rolls and the rod.  The initial closing force is greater than the momentary surge in separating force accompanying impact of a rod front end with the pinch rolls.  The initial parting is maintained until the rod front end has negotiated the downwardly curved path and has passed through the laying head, at which time the initial closing force is released.  The pinch rolls can then either be opened completely to allow the rod to continue running freely therebetween, or  the initial closing force can be replaced by a lower secondary closing force which allows the rod to push the pinch rolls apart to a secondary parting.  The secondary parting continues the driving relationship between the pinch rolls arid the rod, without any accompanying rod deformation.

Abstract: ENGINE ANALYZER WITH CONSTANT WIDTH DIGITAL               WAVEFORM DISPLAY ABSTRACT OF THE DISCLOSURE An engine analyzer for an internal combustion engine includes an analog-to-digital (A/D) converter which digitizes an analog electrical input waveform representing, for example, a secondary or primary voltage waveform of the ignition coil of the internal combustion engine.  The digitized input waveform is stored in the form of digital data in a data memory.  Upon request by the operator of the apparatus, a microprocessor selects digital data stored, and supplies that digital data to a display, which displays a visual representation of the waveform based upon the selected digital data.  The engine analyzer apparatus produces a constant width waveform regardless of engine RPM, by determining the period of the waveform to be stored, and then varying the sample rate at which the A/D converter samples the analog waveform and converts the sampled waveform to digital data.  As a result, the number of data samples, and thus the width of the displayed waveform, is constant.

Abstract: ABSTRACT            A means is provided of measuring the amplitude of a periodic signal, whose maxima and zero crossings have a phase difference of .pi./2, which extracts the amplitude information of a desired phase in which the measurement is to be effected by digitally processing the signal itself. The technique is particularly suitable when the signal-to-noise ratio is very low and the phase reference of the periodic signal is not available, as for instance when an attenuation measurement is to be effected in the field on an optical carrier for telecommunications systems.  Phase locking is achieved by taking pairs of samples in each period, the samples having a .pi./2 separation, digitally filtering one sample of each pair, separately accumulating the two samples from a number of successive pairs, compar-ing the signs of the accumulated samples to provide a phase correction signal, and using the accumulated filtered samples to derive the desired amplitude measurement once phase locking is achieved.

Abstract: "APPARATUS AND METHOD FOR HEATING PLASTIC SHEET MATERIAL"             ABSTRACT OF THE DISCLOSURE         Apparatus is disclosed for heating a plurality of sheets of plastic material between adjacent ones of a plurality of vertically stacked and individually heated platens.  The platens are vertically displaceable together and relative to one another, and any two vertically adjacent platens are vertically separable relative to a fixed hori-zontal pass line to facilitate removing a heated plastic sheet from between the platens and introducing a plastic sheet to be heated therebetween.  Vertical separation is achieved by latching the upper one of two adjacent platens in a fixed holding position above the pass line and lowering the lower one of the two platens and any other platens of the stack therebeneath to position the upper surface of the lowered platen at the pass line.  Sheet discharge and feed mechanisms are then operable respectively to remove a heated sheet from the lower platen and introduce a sheet to be heated onto the lower platen.  In a preferred mode of opera-tion, plastic sheets to be heated are sequentially intro-duced between adjacent ones of the platens from the top of the stack to the bottom thereof and are thereafter removed from between the platens in the same sequence, the elapsed time between introduction and removal providing the required soak time for preparing the plastic sheets for a forming or shaping operation such as in a press.
