Abstract: INTEGRATED CIRCUIT PROTECTION DEVICE             ABSTRACT OF THE DISCLOSURE Disclosed is a protection circuit which may be used, for example, in a television receiver to protect circuitry formed within an integrated circuit from damage due to excessively high voltage transients.  The protection circuit comprises a PNPN structure forming a silicon controlled rectifier (SCR) and metal-oxide-semiconductor (MOS) transistor integral to the SCR structure.  The SCR and the MOS transistors are arranged to form a two terminal protection circuit which is rendered conductive when the potential difference across the two terminals is greater than a predetermined threshold.  One terminal of the protection circuit is connected to an input or output signal terminal of the protected circuit, and the other terminal is connected to a reference terminal to which a reference potential such as ground potential is applied.  Transient voltages appearing at the integrated circuit terminal greater than the predetermined threshold voltage causes the protection circuit to conduct current, thereby dissipating the energy of the high voltage transient and protecting the integrated circuit from damage.  In one embodiment, the gate electrode of the MOS transistor is connected to the reference terminal, and in another to the signal terminal.  The latter connection provides a much larger predetermined threshold voltage than the former, and typically considerably in excess of the supply voltage.

Abstract: Method and Composition for the Evaluation of Phagocytic Response Abstract Methods and compositions for measuring phagocytosis and biochemical activity of phagocytic cells are described.  A sample of blood cells is taken from an organism.  The phagocytic activity of the blood phago-cytes is estimated by the direct addition of a parti-culate material comprising zymosan particles adsorbed with protein having a luminescent chemical admixed therewith.  Alternatively, phagocytic cells from said sample are purified and mixed with zymosan or a polymeric particle chemically coated with protein and luminescent chemical.  When the phagocytic cells are mixed with either of these compositions, the cells engulf the particles thus causing the activation of the cells' biochemical mechanisms.  Oxygen intermediates result from this mechanism causing a reaction with the luminescent chemical resulting in the production of light.  This light is measured on a luminometer and based on the rate of light production and the maximum produced, the phagocytic activity of said cells is measured.

Abstract: ABSTRACT OF THE DISCLOSURE          "ROBUST ESTIMATOR AND METHOD FOR DETERMINING, FOR EXAMPLE, IF SIGN-BIT REPRESENTATIONS OF FULL-WAVEFORM SEISMIC TRACES CAN BE USED IN SUBSEQUENT PROCESSING OF THE DATA, SAY IN EDITING SEISMIC TRACES COLLECTED BY LARGE MULTICHANNEL                    SEISMIC SYSTEMS"           A method is disclosed for determining if sign-clipped variations of full-waveform traces can be used in subsequent cross-correlation processing without undue hard-ship.  In accordance with one aspect, the present invention examines skewness of the amplitude spectrum of the full wave-form.  If the former significantly differs from conventional Gaussian distribution over the frequency range of interest, i.e., the amplitude spectrum is non-Gaussian, sign-clipped versions thereof can be used in subsequent cross-correlation processing without undue loss in processing accuracy.  In another aspect, the present invention is used to edit a series of traces, one at a time, gathered by a large multi-channel collection system.  In this aspect, the different spectral noise estimates, including cross-correlation estimates generated from sign-clipped versions of the full-wave form traces, are advantageously used.

Abstract: ABSTRACT OF THE DISCLOSURE In accordance with the invention a coin sorter is provided which sorts mixed denominations of coins.  The coin sorter comprises a rotatable disc having a resilient surface and a stationary disc having its first surface positioned proximate to the resilient surface of the rotatable disc.  The two discs are positioned sufficiently close such that coins placed between the two disc surfaces are pressed into the resilient surface by pressure from the stationary disc surface.  Accordingly, coins cannot move on the rotatable disc and, as a result, they rotate with the rotatable disc.  Radial movement of the coins is urged by centri-fugal force from the coin rotation, but such movement is prevented by the coins pressed engagement with the resilient surface.  Selected areas of the stationary disc are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force.  The selected areas of the stationary disc which are recessed, guide the coins along a path which results in each denomination of coin escaping from between the two discs at different positions along the periphery or the stationary disc.  A means is provided to remove the upper coin from stacked or shingled coin combinations.  Particularly, the means may be an arcuate elastomer member which retards movement of the upper coin while allowing the lower coin to rotate freely.  Alternately, the means may be a recess in the stationary disc whose entrance allows only single layer coins to enter the recess by sweeping the surface of the lower coin and recirculating any stacked and shingled coins removed thereby.  Recesses and ridges are provided on the underside of the stationary disc which recirculate improperly aligned coins.  In particular, a ridge is provided which recirculates misaligned coins to a recessed area which initially receives coins from the center opening of the stationary disc.  A portion of the recesses in the stationary disc which guide correctly aligned coins are configured to be approximately equal to the largest diameter coin in order to facilitate correct coin alignment.  Another portion of the recesses provide a ejection route for misaligned coins which leads the coins back to the recessed area which initially accepts coins into the area between the two discs.  Yet another portion of the recesses in the stationary disc allow the smallest diameter coin denomination smooth and quick release between the two discs.

Abstract: ABSTRACT OF THE DISCLOSURE         A straight-through four reactor system and pro-cess is disclosed for obtaining high levels of sulfur recovery from acid gas at a cost equal to or less than that required for a standard modified four reactor Claus system.  Two conventional Claus reactors and two cold bed adsorption (CBA) reactors are in series.  Four condensers are provided, one disposed before each of the Claus and CBA catalytic reactors.  A first heater and a first bypass line is disposed between the second condenser and the second catalytic reactor (second Claus reactor) and a second heater and a second bypass line is disposed between the third condenser and the third catalytic reactor (first CBA reactor).  The system is designed to operate either with both CBA reactor in a regeneration mode and the other CBA reactor in a recovery mode.  When both reactors are operating in the recovery mode, the system is similar to the standard modified Claus system.  But when one of the CBA reactors is in a regeneration mode, effluent from the third condenser is heated in the second heater and directed to the CBA reactor on regeneration.  Sulfur is vaporized from the regenerating CBA reactor and is recov-ered in the fourth condenser.  Effluent from the fourth condenser is then passed through the CBA reactor in recovery mode before it passes to the incinerator.
