Abstract: ABSTRACT OF THE DISCLOSURE     A comminuting apparatus wherein a gaseous carrier is employed to transport particulate matter comminuted therein, having a generally cylindrical grinding chamber bounded at one end by a planar rotatable comminuting means and at the other end thereof by a generally annular configuration.   Said other end includes a radial flow classifying means and a semi-toroidal channel segment.        The radial flow classifying means is in the nature of a truncated conically shaped rotor having vane members.     The associated semi-toroidal gas flow directing channel segment is formed by a ring member.  The inner surface of the ring member is contoured arcuately about an upper edge of an annular isolating baffle member disposed substantially parallel to the periphery of the vane members of the classifying rotor intermediate said rotor and an exterior wall of the grinding chamber.        The outer marginal edge portions of the vane members form a smooth continuation of another surface of said ring member.        The inner marginal edge portions of the vane members form a smooth continuation of another surface of said ring member. Said apparatus may also include the following: an annular dependent flange on the downstream side of the ring member and the vane members being complementally i contoured to provide a flange receiving recess at their upper ends; a plurality of venting apertures in an extending flange of a drive shaft supporting sleeve; an isolating chamber, formed by a shroud and the drive shaft supporting sleeve; a fluid intake manifold and a baffle disposed within the isolating chamber, and an exterior surface of the shroud member including a layer of insulating material; an auxiliary product feed conduit located at the apex of a curved upper surface of the semi-toroidal gas flow directing channel segment; an oversize-particle delivery aperture provided in a baffle closely adjacent to the grinding chamber's wall; and a delivery tube adapted to be connected thereto.   ii

Abstract: MICROELECTROCHEMICAL DEVICES            Abstract of the Invention Very stable, polymer-based electrochemical devices, formed by polymerization of thiophene or a derivative such as 3-methylthiophene which is durable in an aqueous electrolyte over a wide pH range, which respond rapidly to chemical or electrical signals, are disclosed.          In one embodiment, the device functions as an extremely sensitive sensor which measures changes in chemical concentration or pH.  For example, a poly-3-methylthiophene-based device is sensitive to as little as 8 x 10-16 moles of an oxidant which reversibly interacts with the polymer, including gas phase oxidants such as I2.  In a variation of the polymer-based device, a catalyst such as a noble metal or an enzyme, is dispersed on or within the conducting polymer matrix so that the device is responsive to chemicals such as H2 and O2 which the polymer would otherwise respond very slowly to.  In a second embodiment, a polymer-based electrochromic device consists of polymer-coated microelectrodes which are individually addressed.  Very high resolution is achieved by separating the microelectrodes by distances on the order of 10,000 Angstroms.  In still another embodiment, the polymer-based device functions as a capacitor with an energy density as high as 200-300 J/cm3 which can operate at frequencies as high as 100 Hz.  Large polymer based capacities are useful for storage of solar energy or as automobile batteries.  Microcapacitors may be incorporated into conventional integrated circuit designs.

Abstract: ABSTRACT             A method of depositing P-type material on one or more semiconductor substrate wafers in a CMOS fabrication process, utilizing boron disks.  The boron disks are passivated by exposing them to nitrogen gas within a reaction chamber, and then subsequently oxidized by flowing gaseous oxygen thereover.  P-type material is diffused from the boron disks onto the surface of the wafers by flowing nitrogen gas over the disks and wafers within the reaction chamber, and subsequently flowing a mixture of nitrogen and oxygen gas over the disks and wafers at a predetermined temperature and flow rate, and for a predetermined length of time.  The wafers produced according to the method of the present invention are characterized by high yield, few surface or near-surface defects, and uniform P+ sheet resistance.  The method is substantially less expensive to implement than prior art ion implantation techniques for fabricating MOS devices.

Abstract: PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS ABSTRACT    A process for producing an organic compound from a hy-drocarbon containing feedstock.  The feedstock is divided into two fractions.  The first is subject to a primary steam reforming reaction.  The reaction product is then combined with the second fraction and reacted with a free oxygen-rich gas in a secondary reforming reactor to form a synthesis gas having a ratio of   between 0.80 and 1.00.  The synthesis gas is then mixed with a hydrogen-rich stream, which has been separated from a purge gas from the synthesis loop, to form a final syn-thesis gas.  The final synthesis gas is injected into a synthesis loop in which the desired organic compound is formed.  The purge gas extracted from the loop is subjected to a physical separation to form a hydrogen-rich gas stream and a residual gas stream.  A portion of the hydrogen-rich stream is recycled to form the final synthesis gas.

Abstract: ABSTRACT     METHOD OF SPIN-WELDING       An end component 3 is spin-welded into the cut end of an extruded tube 1 with the application of axial pressure but without the application of radial pressure to the weld area.  The radial forces required to create a weld are provided by hoop stresses which are formed in the tube by shock-cooling the tube as it emerges from the extrusion die.  When the tube is cut, the hoop stresses cause the cut end of the tube to contract radially prior to insertion of the end component.  To assist in insertion of the end component, a cylindrical skirt thereof 4 is provided with a chamfered end 9.
