Abstract: APPARATUS FOR FEEDING AND ORIENTING WORKPIECES IN A        PRESS Abstract of the Disclosure Apparatus is disclosed for shuttling a workpiece to a work station in a forging press and rotating the workpiece about a vertical axis to orient different portions thereof relative to the work station.  The apparatus includes a work-piece support mounted on a horizontally reciprocable shuttle plate for displacement therewith toward and away from the press and for displacement relative thereto about and along a vertical axis.  A workpiece to be forged is positioned on the workpiece support while the shuttle plate is displaced from the press, and displacement of the shuttle plate toward the press positions a portion of the workpiece at the press work station.  A pair of leveling units are mounted on the shuttle plate adjacent the workpiece support and are operable to support portions of the workpiece outside the work station during a forging operation. During the forging operation, the workpiece support is lowered out of engagement with the workpiece and, following the forging operation, the workpiece support is lowered out of engagement with the workpiece and, following the forging operation, the workpiece support is raised to lift the workpiece from the leveling units and the press anvil at the work station.  The workpiece support is then pivoted about the vertical axis to position another portion thereof at the work station, where-after the workpiece support is lowered for the workpiece to be supported by the anvil and leveling units.  When the entire forging operation has been completed, the workpiece is again elevated by the workpiece support and the shuttle plate is dis-placed outwardly from the press to facilitate removal of the finished workpiece.

Abstract: METHODS, AND APPARATUS, FOR TRANSMITTING HIGH-BIT RATE   DIGITAL DATA IN POWER LINE COMMUNICATION               MEDIA HAVING HIGH HARMONIC NOISE CONTENT                         ABSTRACT OF THE DISCLOSURE        In a power line data communications system, high-bit rate digital data is transmitted through a communications media, having high harmonic noise content, by use of a frequency-modulated chirp waveform. The chirp waveform instantaneous frequency is at a predetermined center frequency at the start of midpoint and end of each bit time, interval, and makes substantially linear frequency changes to a maximum frequency and minimum frequency at selected ones of the one-quarter and three-quarter bit-time-interval times. A binary-one data bit is transmitted by increasing the instantaneous frequency to reach the maximum frequency at the one-quarter interval time, then decreasing the frequency to reach a minimum frequency at the three-quarter interval time, and reducing the instant-aneous frequency thereafter to reach the center frequency at the end of the bit time interval. A binary-zero data bit is transmitted by initially decreasing the instant-aneous frequency to reach the minimum frequency at the one-quarter interval time, then increasing the instantaneous frequency to reach the maximum frequency at the three-quarter interval time, and reducing the instantaneous frequency thereafter to reach the center frequency at the end of the bit time interval.      One presently preferred embodiment of apparatus for transmitting the chirp frequency-modulation signal, and one presently preferred embodiment of apparatus for receiving the chirp frequency-modulated waveform for recovering the data modulated thereon; and associate timing information, are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates generally to fluidized catalytic cracking.  More particularly, the present invention relates to a baffle arrangement that improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit.  The catalytic reac-tor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel.  An inlet riser conduit forming a primary reaction zone extends generally external to and generally parallel with the shell to a location near the top of the vessel.  The upper end of the riser conduit then turns through 180°, preferably through two right angle turns of 90° each, so that the riser conduit enters the vessel either on a horizontal run into the side of the vessel and then turns downwardly, or on a downward run through the top of vessel, into the center of the vessel to form an outlet, discharging downwardly the mixture of hydro-carbon and catalyst.  The mixture is directed against a catalyst disengaging baffle whose surface is at an obtuse angle to the axis of the riser discharge conduit.  The resulting angle of deflection of the flowing mixture is from 10° to 30°, preferably 20°. According to a prefered form of the present invention, a conical catalyst disengaging baffle is arranged with its apex directed toward and the axis concentric with and below the discharge outlet. The conical baffle is also above the stripping zone, so that the mixture is deflected outwardly from the outlet toward the wall of the vessel.  Still further, in a preferred embodiment an annular catalyst disengaging wall baffle is arranged on the inside of the shell for again deflect-ing the mixture, now mostly catalyst, generally down-wardly and toward the stripping zone of the vessel. Preferably, the conical baffle and the wall baffle are arranged within the shell such that the baffles in concert with the riser discharge outlet form a partial cyclone separating zone between the baffles to thereby improve the separation of hydrocarbon vapors from the catalyst.  This cyclone action promotes early disen-gagement of hydrocarbon vapor from the catalyst and reduces undesirable catalyst carryover in the vapor to conventional cyclones through which the hydrocarbon products are recovered.  At the same time, stripping efficiency is also increased by quickly and effective-ly delivering spent catalyst to the stripping zone and undesirable secondary cracking reactions are minimized in the dilute phase by lowering the concentration of spent catalyst in the dilute phase.

Abstract: Inventor:    J. WARNE CARTER, JR. and J. WARNE CARTER, SR.         Invention:   WIND-DRIVEN GENERATOR APPRATUS AND METHOD              OF MAKING BLADE SUPPORTS THEREFOR                 Abstract of the Disclosure Wind generator apparatus employs an induction generator with a wind-driven rotor.  Connection of the induction generator to AC power lines is controlled by apparatus that compares generator rpm and line frequency.          The rotor blades have a pretwisted, varying-chord inboard portion and an untwisted, constant-chord outboard portion.          The blades are self-starting, operate efficiently over a range of wind speeds with constant pitch maintained by a torsional biasing mechanism, and pitch up automatically when the normal rpm operating range is exceeded.  An im-proved blade-supporting spar of low torsional stiffness has an I-beam configuration with filament-wound flanges.          A pitch damper prevents torsional oscillations while permitting the blades to pitch up readily.  The rotor, which includes a teetering hub, is free to weather-vane about the axis of a supporting tower, but a yaw damper limits angular velocity.  A guy wire and gin pole arrange-ment stabilizes the tower and permits easy raising and lowering of the tower.

Abstract: ABSTRACT Foreign protein segments having specific medically or commercially useful biological functions are incorporated in surface proteins of viruses.  The viruses with the incorporated protein segments are convenient agents for introducing the protein segments into animals, such as humans, and are thus useful as vaccines.  Small segments of an original protein exhibiting desired functions are identified, and a DNA fragment having a nucleotide base sequence encoding that segment of the protein is isolated from an organism or synthesized chemically.  The isolated DNA fragment is inserted into the DNA genome of a virus in a manner such that the inserted DNA fragment expresses itself as the foreign segment of a surface viral protein and in such a way that neither the function of the protein segment nor the function of any viral protein critical for viral replication is impaired.

A holding circuit including a low-pass filter and a switching element stores a prior signal value at the sensing amplifier input during the blanking interval, and delays return to normal operation until after the blanking circuit has returned to normal.  Artifact rejection is also improved by limiting atrial pulse output circuit recharge time and by limiting polarization current driven into the ventricular output circuitry by an atrial output pulse.
