Patent EP-0443236-A1 (EP)
Inventor: BESTEL ERNEST FRED
IPC: H01H33/664
Filed: 1990-06-22
Abstract: A cylindrical coil conductor (20) incorporated in a vacuum interrupter comprises a cylindrical body (44) with a plurality of inclined slits (26) therein defining a plurality of current paths (55). The coil conductor is uniformly cylindrical to reduce radial magnetic fields, which tend to cancel the axial magnetic field generated by the coil conductor. The cylindrical coil conductor electrically connects to the rear surface of a main electrode (17) through a copper ring (65) to maintain current on the periphery of the main electrode. The front surface (57) of the main electrode includes a ring-shaped protrusion (85)to define a point of contact with an opposite main electrode. Current flows into the protrusion, through the main electrode to the copper ring, thereby defining a short current path with minimal resistance.

Abstract: Methanol or other alcohol is converted to high octane gasoline components by an integrated process wherein crude aqueous alcohol feedstock is extracted with a liquid extractant containing C₄ ⁺ iso-olefin and reacted to form tertiary-alkyl ethers, such as MTBE. The aqueous raffinate is converted to predominantly gasoline range liquid hydrocarbons in a MTG catalytic reactor, with byproduct alkanes rich in propane and isobutane. Dehydrogenation of C₃-C₅ alkanes from the MTG unit provides propene and isobutene reactants for subsequent etherification steps. Propene from the MTG dehydrogenation step is reacted with water to produce di-isopropyl ether, which may be blended with MTBE and C₆ ⁺ MTG hydrocarbons to produce high octane gasoline. Isobutylene and isoamylenes from the MTG dehydrogenation step can be recovered and recycled as a liquid extractant.

Title: Method of making silicon quantum wires.
Inventor: CANHAM LEIGH-TREVOR
IPC: H01L29/06
Filed: 1990-12-06
Abstract: Luminescent silicon incorporating semiconductor quantum wires is made using a semiconductor wafer 14 as starting material. The wafer 14 is weakly doped p type with a shallow heavily doped p layer therein for current flow uniformity purposes. The wafer 14 is anodised in 20% aqueous hydrofluoric acid to produce a layer 5  mu m thick with 70% porosity and good crystallinity. The layer is subsequently etched in concentrated hydrofluoric acid, which provides a slow etch rate. The etch increases porosity to a level in the region of 80% or above. At such a level, pores overlap and isolated quantum wires are expected to form with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap (1.1 eV) and extending into the red region (1.6 - 2.0 eV) of the visible spectrum.

Abstract: Each phase (L1-L3) is assigned a suitable current sensing device (10, 11, 12) for measuring the present phase currents. The measured currents are supplied to a measuring and control device (21) via a rectifier circuit and a common measuring resistor (2). The measuring and control device (21) selects the switching elements (3, 4, 5) connected in parallel with the current sensing devices (10, 11, 12) in such a manner that within one measuring cycle (MZ), only one switching element is always opened while the other switching elements short-circuit their corresponding current sensing device. Thus, each phase (L1-L3) is individually sensed, and their currents are detected by the measuring resistor (2) and provided as measurement variable to the measuring and control device, several times individually within a determinable measuring period. <IMAGE>
