Abstract: COMMUNICATION ARRANGEMENT FOR                DISTRIBUTED CONTROL SYSTEMS     Abstract A time division switching system having distributed control processors is disclosed.  The distributed processors exchange control messages and cooperate in the completion of talking paths between subscribers.  Each control message includes an address portion defining the destination for the control message and is transmitted to a time-shared space division switch on the same time multiplex lines that speech representations are transmitted.  Control messages are routed by the time-shared space division switch to a control distribution unit where the address portion is interpreted.  When the address portion defines a distributed processor which controls the time-shared space division switch, the control distribution unit transmits the associated control message directly to that processor.          Alternatively, when the address portion defines one of the other distributed processors the control distribution unit transmits the associated control message to the defined processor via the time-shared space division switch.          Additionally, each control message can comprise an intervention portion and an arrangement is associated with each distributed processor which responds to the intervention portions by alternating the functions performed by an associated distributed processor.

Abstract: VOLTAGE CONTROL SYSTEM FOR ELECTROSTATIC OIL TREATER Abstract of the Invention An automatic voltage control system controls the firing angle of a solid state switch (20), in turn the voltage applied to the primary winding (12) of a step-up transformer (10), in turn the voltage applied to the grid (38) and in turn the electric field intensity between grid elements (38) in an electrostatic separation process.  Two voltage control signals are generated in the control system.  The first voltage control signal is a protective control signal generated to maximize the voltage applied to the primary winding under normal operating conditions and to reduce the voltage to zero for a short time period following abnormal operating conditions then to reapply voltage to the primary winding (12) again.  The second voltage control signal is a periodic signal of adjustable rate and frequency that functions as a variable upper limit to the magnitude of the first control signal.  The first control signal as limited in magnitude by the second control signal controls the firing angle of a solid state switch (20), in turn the voltage applied to primary winding (12) and in turn the electric field intensity between grid elements (38).  The electric field intensity increase then decreases periodically to coalesce small droplets of a first fluid dispersed throughout a second fluid into larger droplets.  During the increase in electric field intensity, small droplets of the first fluid are coalesced into larger droplets.  The decrease in electric field intensity encourages continued coalescence of larger droplets.  Any droplets not coalesced during a given cycle of field intensity are subjected to subsequent periodic variations in field intensity as the electrostatic separation process through flow is continuous and the electrostatic field intensity variation is repetitive.

Abstract: HIGH EFFICIENCY PARTICULATE AIR FILTER     AND METHOD OF FABRICATING SAME   Abstract of the Disclosure A high efficiency particulate air filter, and a method of fabricating the same, are disclosed, with the filter being characterized by being lightweight and readily disposable after use.  Further, the filter may be fabri-cated in a basic or universal form, which permits it to be utilized to form any one of a number of possible specific mounting configurations by the placement of one or more specifically designed headers about the outer periphery. The filter comprises a sheet of HEPA filtering media folded upon itself in accordion fashion to form a filter pack, and a relatively thin and lightweight peripheral frame surrounding and supporting the pack.  The frame is composed of a relatively hard, crust-like, air impermeable molded material which is self-bonded and sealed to the filter pack to effectively preclude the leakage of air therebetween. Internal integral reinforcing ribs are formed in the material of the frame along at least two opposite sides of the pack, to provide sufficient strength to permit the filter to be mounted against a pressure seal or the like.

Abstract: ABSTRACT OF THE DISCLOSURE       An intravenous monitoring system in which dynamic reference threshold circuitry is used to provide output signals indicating the presence of liquid passing through the drip chamber of an intravenous feeding apparatus.  A light sensor that detects the presence of liquid passing through the drip chamber generates a detecting signal that is amplified and processed by the dynamic reference threshold circuitry.  The dynamic reference threshold circuitry comprises a comparator circuit, and a D.C. component reference circuit that provides the reference threshold to the comparator circuit.  The amplified detecting signal is directed both to an input of the comparator circuit and the D.C. component reference circuit.  The D.C. component reference circuit uses a diode to produce a voltage drop in the amplified detecting signal and an RC circuit to both store and emit a residual signal when there is a sudden drop in the amplified detecting signal.  A resistor is connected in parallel with the diode to provide a leakage path around the diode and thereby form a proportional reference threshold.  Whenever the reference threshold exceeds the amplified detecting signal the comparator circuit generates an output signal indicating liquid passing through the drip chamber.  If streaming occurs in the drip chamber an extending output signal by the comparator circuit will indicate this.

Abstract: Worm-drive presses, particularly those that operate on combustible material, require the best possible match between charge, compression and postcompression, a regulated input of material, high compression pressure, and as complete as possible extraction of liquid. These ends are served by at least one guide element that engages in the front end of the worm and the adjacent outlet (3), this permittong axial guidance of the extrudant and thus helping prevent breaks in the extrudant. Adjustment of the crosssection and thus the counter-pressure in an extension piece (18) of the outlet (3), is preferably achieved by means of spring-loaded, axially displaceable, spreadable wall sections (21) of the extension piece (18), and a feed regulation system that depends on this, has covers that are preferably controlled by the longitudinal displacement of the extension piece (18) that is governed by pressure. A screen or the like is installed between a reduction system in the input hopper (2) and the rear end of the worm in the input hopper (2). The guide element passes through the wall (5) of the worm-drive tube (1), is driven by a worm gear, and continually cleans the outlet for the expressed liquids which is provided by its installation slit (4) in the wall (5).

Abstract: ABSTRACT OF THE DISCLOSURE           A  fiber-optic  transducer  apparatus,  and  a related method of manufacturing it, for particular use in medical applications such as invasive blood pressure and body temperature measurement.   The apparatus includes a catheter comprised of a sheath and an enclosed first set of optical fibers for transmitting a light beam to and from the remote end of the catheter, where a transducer modulates it  in accordance with the variable to be measured, e.g., blood pressure.  A photosensor located at the near end of the catheter measures the modulated intensity of the returned beam, to produce a correspond-ing measurement signal.   The catheter is further com-prised of a second set of optical fibers located within the sheath,  for transmitting a reference light beam to and from the remote end of the catheter.   A second photosensor measures  the  intensity of  the returned reference light beam, to produce a correction signal indicative of variations in transmittance caused by bending of the catheter.  It is presumed that the effects of such bending are the same for the second set of optical fibers as for the first set, so the apparatus adjusts the measurement  signal  in accordance with the correction signal,  to produce  an adjusted measurement signal that is substantially insensitive to the effects of such bending.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for providing a vaporized heavy hydrocarbon feedstock which avoids the formation of coke in the feed heaters and is useful in a process for upgrading and/or converting the heavy hydrocarbon to lighter products, such as in a thermal hydrodealkylation process.  In the method, a heavy hydrocarbon feedstock material is heated to a temperature below its coking point, then mixed with hydrogen-rich gas heated to a temperature sufficient so that upon mixing with the hydrocarbon feedstock the latter is heated and vaporized without forming coke.  Alternatively, the heavy hydrocarbon feedstock can be fractionated to provide a light IBP-550°F liquid fraction, and a heavy 550-850°F liquid fraction.  The light fraction is mixed with hydrogen-rich gas and heated to a temperature sufficiently high so that upon being mixed with the heavy liquid fraction the latter is heated through its dry point and vaporized without coking.  The resulting vaporized hydrocarbon material is usually further heated before being fed to a reaction step, such as a hydrodealkylation reaction to produce a hydrodealkylated product.
