Abstract: POLYPHONIC ELECTRONIC MUSIC SYSTEM                ABSTRACT OF THE DISCLOSURE         Simultaneously played notes are automatically provided with different voices.  Voices are assigned to notes depending upon their relative frequencies and the number of keys played.  Generally, the three lowest notes and the highest note are sounded in different voices.          When fewer than four keys are played voices are doubled up.  In one embodiment, time division multiplex digital logic signals representative of the played keys are applied to memory and comparator circuits.  If a scan indicates no change in played keys, the comparator pro-vides an enabling signal to a monostable and enable logic circuit.  A priority selector circuit provides information representative of the three lowest keys and the highest key played to a monostable and enable logic circuit.  The monostable and enable logic circuit provides information representative of the three lowest keys played, the highest key played, and the total number of keys played.  This information is combined with octave information and note time slot information in four programmable counter circuits which divide four input frequencies from a rate scaler frequency generator to produce four tone signals having fundamental output frequencies fl - fH corresponding to the three lowest notes and single highest notes played.          The four programmable counter circuits provide control voltages corresponding to the played notes.  The tone signals and control voltages are applied to voltage con-trolled gates and filters which provide the voicing to produce different orchestral effects on different notes.          The outputs of the voltage controlled gate and filters are applied to at least two output channels to avoid electrical cancellations.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method for the polymerization of vinyl chloride or a monomer mixture mainly composed of vinyl chloride in an aqueous polymerization medium is proposed, in which a water-insoluble polymerization initiator, being solid at room temperature, is dispersed in the aqueous medium.  The initiator has a particle size distribution of 50 µm or finer, and is added to the polymerization mixture which is maintained at a tempera-ture where the half-life period of the initiator is 120 minutes or longer or, alternatively, over a duration equal to or shorter than one-tenth of the half-life period of the initiator at the temperature of the polymerization mixture.  By this method the polymerization can homogeneously proceed to produce vinyl chloride polymers having a uniform particle size distribution, excellent heat stability and less fish-eyes when fabricated into sheets.

Abstract: ABSTRACT        A system for recovering waste heat from a stream of heated gas is disclosed.  The system includes a convection heat transfer chamber, a boiler tank, and a plurality of heat pipes thermally interconnecting the convection heat transferchamber with the boiler tank.  Each of the heat pipes includes an evaporator section which is disposed in heat transfer relation with a stream of heated gas flowing through the convection heat transfer chamber, and a condenser section disposed in heat transfer relation with a volume of water disposed within the boiler tank. The evaporator sections and condenser sections are totally enclosed within the convection heat transfer chamber and boiler tank, respectively, and are connected in closedcycle fluid communication with each other.  The heat pipes contain a working fluid which is characterized by a thermodynamic cycle in which the working fluid is vaporized in the evaporator section and flows to the condenser section where it is condensed to the liquid phase and returns in a closed cycle to the evaporator section, thereby transferring heat energy from the heated gas stream in the convection heat transfer chamber to the volume of water contained in the boiler tank.  In a regenerative arrangement, exhaust gas discharged from the convection heat transfer chamber is recycled to the input of the convection heat transfer chamber to provide high mass flow at low velocity for optimum efficiency.  In another arrangement, superheated steam is provided by a pair of heat pipe boilers whose convection heat transfer chambers are connected in series, with the evaporator of the steam generating unit being located downstream of the superheat unit and the input of the superheat unit being the steam output of the steam generating unit.

Abstract: PREPARATION OF OVERBASED MAGNESIUM SULFONATES    Abstract of the Disclosure Process of preparation of fluid overbased, particularly highly overbased, magnesium-containing colloidal dispersions wherein a partial mixture is formed of an oil-soluble sulfonic acid as such or admixed with an oil-soluble aliphatic hydro-carbon monocarboxylic acid, a volatile aliphatic or aromatic or chlorinated hydrocarbon solvent, a special grade or readily reactive form of magnesium oxide for neutralization and over-basing purposes, and an alcohol, carbonating the mixture with a controlled limited amount of carbon dioxide, in the presence of an added activator, adding a nonvolatile diluent oil, sta-bilizing the colloidal dispersion, removing undesired sediment and then heating to distill off the volatile materials.  The final overbased compositions have excellent utility as lubri-cating oils for use in diesel engines and internal combustion engines, and they possess, among other properties, the corro-sion inhibiting and antioxidant properties, the ability to re-duce engine wear and to inhibit formation of undesirable and harmful deposits on engine parts.  In the process, a stabilized post-reaction composition is produced, as indicated above, util-izing a limited amount, which is substantially less than the stoichiometric amount, of carbon dioxide per mole of over-basing magnesium present.

The vital decoder includes means for sequentially producing diverse multi-bit checkwords based on predetermined words generated by the system indicative of system performance, these predetermined words including the display words and the display echo words.  The checkwords are produced in response to receipt of the message words and may be based additionally on diag-nostic testing routines formed before, during, and after receipt of the keyboard in-structions.  The vital decoder compares each of the generated checkwords to a pre-determined constant mulit-bit pattern and produces a validation signal if sequential ones of the checkwords are complementary and are identical to the multi-bit pattern, whereupon the vital decoder activates output devices in accordance with the specific keyboard instructions, but only in the event that valid system operation is indicated by means of the presence of the validation signal.

Abstract: AN EXHAUST BRAKE MODULATING CONTROL SYSTEM                   Abstract of the Disclosure An exhaust brake modulating control system is provided for an internal combustion engine having a turbo-charger and source of pressurized fluid.  The system includes a double-acting piston-cylinder assembly having one cylinder end communicating with the engine exhaust manifold and an opposite end separated from the one end by a piston head. An adjustable control valve is provided having an outlet connected to the cylinder second end, and a plurality of inlets selectively connected to the outlet.  One inlet communicates with the pressurized fluid source and a second inlet is vented to the atmosphere.  Communicating with the exhaust manifold is an inlet of a hollow section in which a rotor is rotatably mounted.  The hollow section has an outlet separated from the inlet by the rotor.  The outlet communicates with the turbine wheel chamber of the turbo-charger.  When the rotor assumes a first selected position, substantially unrestricted exhaust gas flow past the rotor occurs.  When the rotor assumes a second selected position, gas flow is substantially blocked by the rotor.  The rotor and piston head are operatively connected whereby the rotor is responsive to relative movement of the piston head within the cylinder.  When the control valve connects the cylinder second end to the pressurized fluid source, the fluid pressure will balance a predetermined gas pressure on the piston head whereby the head will cause the rotor to assume a position that generates a predetermined exhaust braking effect.
