Patent CA-2280380-A1 (CA)
Inventor: HAIDER M ISHAQ
IPC: D01F6/84
Filed: 1999-08-16
Abstract: The present invention discloses and claims a novel process for the heat treatment of high denier filaments of a thermotropic liquid crystalline polymer. Preferred embodiments include process for the formation of heat treated filaments of a few wholly aromatic polyesters and polyesteramides. The process involves: (a) heating of a thermotropic liquid crystalline polymer to above its melting transition temperature; (b) passing said molten polymer through an extrusion chamber equipped with an extrusion capillary of an aspect ratio of greater than about I and less than about 15 to form a filament; (c) winding the filament on to a bobbin at a low tension and draw-down ratio of at least about 4; and (d) heat treating the filament directly on the bobbin at suitable temperature and pressure conditions for a sufficient period of time. The filaments so formed are of at least 50 denier per filament (dpf) and feature essentially uniform molecular orientation across the cross-section. The heat-treated filaments feature remarkably good tensile properties retaining at least 80 to 90 percent of the properties expected of conventional low denier (5 to 10 dpf) filaments.

Abstract: A process for the recovery of copper and nickel from a copper and nickel sulphide concentrate in slurry form. The slurry is subjected to a biological oxidation turning the copper sulphide to soluble copper sulphate and the nickel to nickel sulphate. The liquid containing the sulphates is separated from the slurry and treated with a solvent extraction reagent so that copper ions are exchanged by the reagent for hydrogen ions to produce a raffinate which is high in sulphuric acid and low in copper sulphate. The solvent extraction reagent is then stripped from the raffinate with a sulphuric acid solution. Copper is electrically harvested from the sulphuric acid solution and a portion of the copper depleted raffinate is returned to form a slurry with additional ore for subsequent biological oxidation. Nickel is recovered from the remaining portion of the raffinate. The preferred bacterium is at least one of Thiobacillus Ferro-oxidans, Thiobacillus Thio-oxidans, Leptospirrilum Ferro-oxidans, Thiobacillum Caldus, Acidimicrobium and Sulpholobus.

Title: Combination gas disengaging downcomer-rejuvenation tube for in-situ slurry catalyst rejuvenation
Inventor: COULALOGLOU CONSTANTINE A
IPC: B01J23/94
Filed: 1998-05-05
Abstract: A reversibly deactivated, particulate catalyst in a hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through (i) a gas disengaging zone to remove gas bubbles from the slurry and increase its density, (ii) a downcomer which feeds the gas reduced, dense slurry into the bottom of a rejuvenating tube and applies a positive hydrostatic pressure to the tube, (iii) a catalyst rejuvenation zone in which a catalyst rejuvenating gas, which also acts as a lift gas, contacts the catalyst in slurry to form a catalyst rejuvenated slurry and, (iv) back into the slurry body. Removing gas bubbles prior to rejuvenation improves the rejuvenation efficiency and the downcomer reduces the amount of rejuvenation gas required to maintain slurry circulation through the tube.

Abstract: In three-phase applications, the direction of rotation can be determined from signal flows in the phase conductors, usually on the basis of indicator diagrams. According to the invention, the individual phases are traced at given time periods and the measuring values or the interpolated approximation values or just the signs of the values are evaluated by means of an evaluation algorithm in order to determine the direction of rotation at at least two points in time. In addition to the basic method, preferably half-wave rectified signal flows from individual phase conductors are evaluated according to an ideal sinusoidal flow. The inventive method can be advantageously used in conjunction with a digital overload relay to determine the direction of rotation, whereby an available digital signal control device and/or signal processing device is used.

Title: Stabilising thermally beneficiated carbonaceous material
Inventor: CONOCHIE DAVID STEWART
IPC: C10B57/08
Filed: 1998-06-23
Abstract: A method of stabilising a thermally beneficiated carbonaceous material is disclosed. The method includes the steps of supplying a charge of the carbonaceous material at an elevated temperature to a process vessel to form a packed bed and cooling the carbonaceous material to a target temperature by indirect heat exchange. The method is characterised by supplying an oxygen-containing gas to the packed bed to partially oxidise the carbonaceous material to a required degree to stabilise the carbonaceous material prior to the carbonaceous material reaching the target temperature. The method is also characterised by removing heat from the packed bed that is produced by oxidation of carbonaceous material to control the temperature of the carbonaceous material during oxidation to avoid thermal runaway.

Title: Method and apparatus for dynamically generating multiple level decision thresholds of an m-ary coded signal
Inventor: PAYER DANIEL G
IPC: H04L25/06
Filed: 2000-01-17
Abstract: A method and apparatus for dynamically generating multiple level decision thresholds of an M-ary demodulated signal for decoding the signal. The threshold values are obtained by obtaining the maximum and minimum peak values of the demodulated M-ary signal, averaging these peak values and subsequently processing these averaged values to establish the threshold for the particular M-ary signal. Infinite impulse response filters may be advantageously used in the averaging process and these filters may be preloaded with maximum and minimum peak values such that decision threshold levels may be generated immediately after receiving the M-ary demodulated signal.

Abstract: The storage stability of bleach-activating acetonitrile derivatives in solid detergent compositions was to be improved. This was essentially achieved by the use of compounded compounds corresponding to formula R1R2R3N x CH2CN X-, in which R1, R2 and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. "Compounds" of this type are produced by drying in vacuo, for which purpose a suspension of the acetonitrile derivative and a solid carrier material is introduced into a mixer and the resulting mixture is dried with superheated vapor. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach boosting compound.

Abstract: There is disclosed a vehicle-mounted device with a sleep function for use in a road-to-vehicle communication system. After having indicated a switching period T1 and reception frequencies F1, F2 to a frequency switching controller, a controller stops operation of an internal counter, and enters a sleep mode until it cancels the sleep mode in response to a detected signal from a receiver. While a vehicle with the vehicle-mounted device is running outside of a communication range of a road radio unit installed at a toll gate or the like, the frequency switching controller independently performs a frequency search process on an RF module, and the controller is in the sleep mode. Therefore, the vehicle-mounted device has a relatively low power requirement.

Abstract: L'invention concerne un boîtier support de composant électronique (100) et un procédé de fabrication. Un support d'élément non conducteur doté de colonnes verticales (110) et de canaux de guidage (108) permet une progression rapide et précise des conducteurs du composant par rapport à un réseau de conducteurs (104). Des perforations de forme spéciale (116) dans ledit réseau (104), adjacentes aux canaux de guidage (108) et alignées sur eux, reçoivent les conducteurs, dénudent la quantité nécessaire d'isolation, et sectionnent lesdits conducteurs (124) à la longueur appropriée, en une seule étape de fabrication. Les jointures entre les conducteurs et le réseau de conducteurs (104) sont réalisées comme suit : ajustement serré, technique de liaison classique (par exemple, soudure ou soudure par thermocompression), ou autre tehcnique. En outre, les perforations (116) permettent une relaxation des contraintes exercées sur les conducteurs dans le boîtier assemblé, et permettent aussi de maintenir les jointures entre le réseau de conducteurs (104) et les conducteurs à l'extérieur du boîtier, ce qui réduit au minimum le volume global du boîtier. On peut également utiliser les perforations (116) comme masques à énergie laser dans le dénudage d'isolation sur les conducteurs, au voisinage desdites perforations (116).
