Patent CA-2211813-A1 (CA)
Inventor: ALAMDARI HOUSHANG
IPC: H01C7/112
Filed: 1997-08-13
Abstract: The invention concerns novel varistors based on zinc oxide and a method for making same, which consists in using as base products nanocrystalline powders obtained by high-intensity mechanical grinding and in subjecting the mixture resulting from said nanocrystalline powders a consolidating treatment such as sintering, in suitably selected temperature and time conditions so as to retain the smallest possible grain size of ZnO. The resulting varistors have a very fine homogeneous microstructure and an average grain size characteristically not more than 3pm, i.e. five times smaller than standard materials. Said novel varistors have a larger number of grain boundaries per unit length unit and therefore a much higher breakdown voltage. Said voltage is characteristically higher than 10 kV/cm and can reach 17 kV/cm which is almost one order of magnitude above the breakdown voltage of standard varistors. The non-linearity coefficient of the current-voltage curve is also improved, and is greater than 20 and can reach values as high as 60. Moreover, the leakage currents below the breakdown voltage of said varistors, are much lower.

Patent CA-2223138-A1 (CA)
Inventor: SEMOROZ CHRISTIAN
IPC: B66B3/00
Filed: 1997-12-02
Abstract: A system and method for optimally allocating elevator cars of an elevator group to serve downpeak traffic.   The system monitors a "snap shot" of pending down hall calls and forms groups based upon an initialized floor separation value or response rage.  If the number of groups formed is greater than the number of available elevator cars in the elevator group, the system increments the floor separation value by "+1' and regroups the "snap-shot" of pending down hall calls. This procedure may be repeated until the number of formed groups is equal to or less than the number of allocable elevator cars. The system may then allocate each formed group to a respective available elevator car to serve the downpeak traffic.

Patent CA-2225684-A1 (CA)
Inventor: VERDEJO FRANCISCO A
IPC: B65D17/50
Filed: 1997-04-11
Abstract: A vacuum closure comprises a metal panel (32), typically surrounded by a moulded plastics band (34), the panel having a concave depression (50) with a vacuum release hole (56) located therein. A plug of plastisol material (60) is deposited into the depression so as to form a removable seal for the hole (56). The hole is formed with an upturned annular side wall to form a convergent chimney (58), and the plug is chosen so as to be adherent to the lacquer coating on the underside of the metal panel, but non-adherent to the lacquer coating on the top of the metal panel. The plastisol plug (60) can therefore be removed to release the vacuum within the container via the hole (56), thereby facilitating release of the closure.

Title: Improvements in or relating to the manufacture of extrusion dies
Inventor: FELDCAMP EDWARD GEORGE
IPC: B21C25/02
Filed: 1996-07-04
Abstract: An extrusion die comprises a die cavity having a shape corresponding to the cross-sectional shape of the required extrusion, and a preform chamber in communication with the die cavity, the preform chamber being of generally similar shape to the die cavity but of greater cross-sectional area, so that regions of the preform chamber communicate with corresponding regions respectively of the die cavity. Each region of the preform chamber has a bearing length which is so determined in relation to its dimensions and position that, in use, extrusion material passing through each region of the preform chamber is constrained to move at a velocity such that the material passes through all regions of the die cavity at a substantially uniform velocity. The die cavity itself is of uniform, preferably zero, bearing length so that the extrusion process is controlled solely by adjustment of the preform chamber, such adjustment then being readily quantifiable and repeatable.

Title: Hydrocracking of heavy hydrocarbon oils with conversion facilitated by control of polar aromatics
Inventor: BENHAM N KELLY
IPC: C10G47/26
Filed: 1996-12-19
Abstract: A process for hydrocracking a heavy hydrocarbon oil feedstock, a substantial portion of which boils above 524 ~C, is described which includes the steps of:  (a) passing a slurry feed of a mixture of heavy hydrocarbon oil feedstock and from about 0.01-4.0 % by weight (based on fresh feedstock) of coke-inhibiting additive particles upwardly through a confined vertical hydrocracking zone, the hydrocracking zone being maintained at a temperature between about 350~  and 600 ~C a pressure of at least 3.5 MPa and a space velocity of up to 4 volumes of hydrocarbon oil per hour per volume of hydrocracking zone capacity;  (b) removing from the top of the hydrocracking zone a mixed effluent containing a gaseous phase comprising hydrogen and vaporous hydrocarbons and a liquid phase comprising heavy hydrocarbons; (c) passing the mixed effluent into a hot separator vessel; (d) withdrawing from the top of the separator a gaseous stream comprising hydrogen and vaporous hydrocarbons; (e) withdrawing from the bottom of the separator a liquid stream comprising heavy hydrocarbons and particles of the coke-inhibiting additive; and (f) fractionating the separated liquid stream to obtain a heavy hydrocarbon stream which boils above 450 ~C said heavy hydrocarbon stream containing said additive particles, and a light oil product. According to the novel feature, at least part of the fractionated heavy hydrocarbon stream boiling above 450 ~C is recycled to form part of the heavy hydrocarbon oil feedstock at a lower polarity aromatic oil is added to the heavy hydrocarbon oil feedstock such that a high ratio of lower polarity aromatics to asphaltenes is maintained during hydroprocessing.  This provides excellent yields without coke formation.
Patent CA-2240688-A1 (CA)
Inventor: GENTRY ARTHUR RAYBURN
IPC: B01J29/40
Filed: 1996-10-11
Abstract: Petroleum products are refined in an integrated hydroprocessing scheme involving a hydrocracking stage (1) and subsequent dewaxing stage (16). Materials boiling in the middle distillate or lube oil range may be dewaxed. The bottoms streams (12, 34) and optionally other streams from each stage are maintained separately from one another during processing. Dewaxing may occur using either hydroisomerization catalysts or shape-selective catalysts or both in series. One embodiment employs a baffle (14) in the flash zone of a fractionator (13) to separate bottoms streams from each other. Alternatively, the effluent (4) from the hydrocracking stage may be processed separately from the effluent (18) from the dewaxing stage. The bottoms fraction from the dewaxing stage may be recycled back to the hydrocracking stage for futher processing or used as lube base stock.

Title: Fountain coating applicator and fountain coating applicator support beam
Inventor: GOECKS ROGER L
IPC: B05C11/04
Filed: 1999-01-26
Abstract: Two coating supply tubes extend parallel to one another and run the full width of a moving substrate in the cross machine direction. Coating is supplied separately to each supply tube from opposite ends. The supply tubes discharge coating through spaced metering holes into an application chamber defined between a sidewall mounted to each supply tube. The counterflow arrangement of the coating supply tubes results in the fall off of coating pressure in one tube being cancelled out by the increased pressure in the other tube. The fall off may be further counteracted by varying the spacing between metering holes the greater the distance from the coating inlet, by varying the diameter of the metering holes, or both. The tendency of the heated coating to cause a temperature gradient may be counteracted by cantilevering the applicator head on arms from a support beam through which a temperature controlling fluid is circulated.
