Abstract: D-20,375 ERROR CORRECTION FOR SIGNALS EMPLOYING     THE MODIFIED DUOBINARY CODE   by Adam Lender ABSTRACT OF THE DISCLOSURE         Single errors can be detected and corrected in a signal employing a 3-level modified duobinary code.  Error correction is predicated on the concept of maximum likelihood of error for the bit having the maximum departure from normal amplitude (error differential).  A converter accepts the modified duobinary signal, decodes the signal to obtain a binary output signal and determines the error differential for each bit.  Bits of the binary output signals are temporarily stored in a sequential storage device.  The error differential is applied to an input of an error analyzer.  An error detector determines if an error has occurred during an error correction interval which interval is established by successive extreme levels of the modified duobinary signal.  The error analyzer tracks the location of the bit having the largest error differential during each error correction interval.  A plurality of bit correctors, one for each time slot of the sequential storage device, operate in combination with the error detector and the error analyzer to alter the bit having the highest error differential following detection of an error.

Abstract: METHOD AND APPARATUS FOR FEEDING CONDENSATE TO A HIGH PRESSURE VAPOR GENERATOR                      ABSTRACT         A mechanical arrangement to reduce drastically the energy consumption for pumping condensate to feed high pressure vapor generators for power generation, industrial processing, and heating systems.  Involved is a method to pump the con-densate into one condensate receiver located at the suction side of the condensate feed pump, and to bleed high pressure vapor from the vapor generator into the condensate receiver for imposing a pressure head upon the condensate therein to be approximately the same as that in the generator, and thus the pressure difference between the suction side and the discharge side of the pump is drastically reduced while pumping the condensate into the generator, with the result that the energy consumption of the pump is also drastically reduced.  The receiver is full of high pressure vapor while the condensate therein is drained by the pump, and the high pressure vapor means energy.  Further new methods are involved to reduce the vapor pressure in the receiver by returning the vapor to the system or to utilize it, as disclosed in the application. Generally speaking, at least two closed receivers operated in series are required for the method of restoring the vapor in the receivers to the generator after the condensate is pumped into the generator.  The invented receivers are also designed for condensate healing with almost no energy consumption.

Abstract: ABSTRACT OF THE DISCLOSURE         A mass of diamond crystals contacting a mass of elemental silicon is confined within a pressure-transmitting medium.  The resulting charge assembly is subjected to a pressure of at least 25 kilobars, causing application of isostatic pressure to the contacting masses, which dimensionally stabilizes them and increases the density of the mass of diamond crystals.  The resulting pressure-maintained charge assembly is heated to a temperature sufficient to melt the silicon, at which temperature no significant graphitization of the diamond occurs, whereby the silicon is infiltrated through the interstices between the diamond crystals producing, upon cooling, an Adherently-bonded integral body.  The resulting body consists of a mass of diamond crystals adherently bonded to each other by a silicon atom-containing bonding medium consisting essentially of silicon carbide and elemental silicon. The diamond crystals range in size from about 1 micron to about 1000 microns.  The density of the diamond crystals ranges from about 80% by volume up to about 95% by volume of the body. The bonding medium is distributed substantially uniformly throughout the polycrystalline diamond body.  At least about 85% by volume and preferably 100% by volume of the portion of the bonding medium in direct contact with the surfaces of the diamond crystals is silicon carbide.  The diamond body is substantially pore-free, and is useful as an abrasive, cutting tool, nozzle or other wear-resistant part.

Abstract: REGULATOR WITH SHORT CIRCUIT PROTECTION                   Abstract Of The Disclosure A deflection circuit coupled to a deflection winding produces scanning current in the winding.  A deflection rate voltage is developed at a first terminal of the deflection circuit.  A source of operating voltage supplies energy to the deflection circuit, and a sensing circuit coupled to a source of voltage representative of an energy level in the deflection circuit produces an error signal for a control circuit that provides first and second control signals.  A controllable switch coupled to the source of operating voltage and the first terminal provides operating current to the deflection circuit through the controllable switch.  A first portion of the deflection rate voltage, under normal conditions, commutates off the controllable switch.  The first control signal, coupled to a control terminal of the switch, switches the controllable switch into conduction, for modulating, under normal operating conditions, the duration of conduction of the controllable switch during each deflection cycle, thereby regulating the supply of energy coupled to the deflection circuit.  The second control signals turn off the controllable switch under fault conditions when the deflection rate voltage fails to commutate off the controllable switch prior to the occurrence of the second control signals.

Abstract: ABSTRACT OF THE DISCLOSURE          A novel wind driven electrical power generator is provided herein.  It includes bladed wheel means which are mounted for rotation about an axis and which are adapted to be operatively connected to electri-cal power generator means.  It also includes means defining a plurality of air flows for simultaneously impinging upon different portions of the wheel means.  The air flow means comprises a first primary air duct means for directing a first air flow onto a first portion of the wheel means, and auxiliary air duct means for directing a second air flow onto a second por-tion of the wheel means, the auxiliary duct means comprising a pair of ducts disposed upon opposite sides of the wheel means, and manifold means for receiving the air flows conducted through the pair of ducts and for merging the flows into the second air flow.  This structure thus cumulatively effects rotation of the wheel means and consequently the operation of the electric power generator means  for the generation of electric power.  The novel structure permits capture of wind currents within a variable direc-tional range, and enables greater dynamic pressures, with correspondingly large forces to be impressed on the bladed wheel means, with a substantial increase in dynamic and static pressure on the wheel means.

Abstract: ABSTRACT OF THE DISCLOSURE           An  electronic  monitoring  circuit  measures  the amount of energy  consumed  by a  system and displays  the corresponding  cost of  the energy.   An alarm circuit  is triggered if the cost exceeds a predetermined amount over a given period of time.   The monitoring circuit includes an electromagnetic coil which senses the magnitude of the input current and generates a d-c voltage having an amplitude corresponding to the current magnitude.   The d-c voltage drives a voltage-controlled oscillator to generate an a-c signal having a frequency corresponding to the d-c voltage amplitude.   The oscillator  has  been preset so that  the generated a-c signal has a frequency representing a unit of cost of electrical power corresponding to the sensed current magnitude. A multivibrator generates a pulsed dlgital signal corresponding  to the  a-c  signal  frequency,  each  pulse indicating a unit of cost for the electrical power consumed.          The pulses are accumulated in a series of decade counters which are connected through a decoder to a seven segment read-out unit for displaying the cumulative cost of  the energy consumed.   The counters are monitored by an alarm circuit  which is  triggered  in  response  to  the  count exceeding a predetermined value in a given period of time.          Reset circuits  periodically returns the counters and alarm circuit to zero to begin a new monitoring period.

HARKNESS            ARTICLE LOADING AND HANDLING DEVICE               ABSTRACT OF THE DISCLOSURE Apparatus to load, transport, and unload cylindrical bales of material generally comprising a frame disposed on a trailer.  The end pickup mechanism generally comprises a pair of forks secured to a shaft rotatably secured to the end of the trailer and a second set of arms extending downwardly to the ground at an angle and a set of tines pivotally secured to the end of said arms to allow limited pivotal action relative to the ground.  The tines are tapered to permit horizontal pickup of a bale of material which upon rotation of the shaft transmits the bale to the vertical arms which are moved to a horizontal position onto a second set of arms on a second shaft.  By rotation of the second shaft the bale is moved to a third set of arms and the bale is moved sequentially along the trailer in this manner.  The bales are unloaded by reversing the direction of the shafts.          This process permits picking up of the bale, moving it along the trailer, transporting the bale, and unloading it by reversing it along the trailer and placing the original bottom of the bale back on the ground so that no further waste will occur in the bale.

Abstract: ABSTRACT OF THE DISCLOSURE       A multispeed transmission having an automatic shift control system having an automatic shift valve which is biased for upshift by a force increasing with output speed of the transmission and is biased for downshift by a force increasing concurrently with torque demand, to provide upshifts at speeds increasing with torque demand and downshifts at lower speeds.  The shift valve controls the supply of shift fluid pressure to the ratio-engaging devices to establish low and high ratio drives.  A regulator valve increases the shift fluid pressure with an increasing lagging torque demand signal.          A modulator valve is controlled by an engine fuel feed or throttle to provide a concurrent torque demand signal pressure concurrent with throttle movement for the shift valve.  The lagging torque demand signal is more concur-rent with engine torque and power, such as the gasifier pressure of a gas turbine engine, or the supercharger pressure of an internal combustion engine.  The transmis-sion is shifted immediately in response to torque demand, and the shift pressure is proportional to the engine torque and speed at the time of the shift.
