Patent CA-2145530-A1 (CA)
Title: Gasoline upgrading process
Inventor: FLETCHER DAVID L
IPC: C10G35/04
Filed: 1993-10-19
Abstract: A cracked FCC naphtha is withdrawn through line (12) and passes to a mercaptan oxidation (sweetening) unit (13) in which the mercaptans are converted to higher boiling disulfide compounds. The effluent from the mercaptan oxidation unit is then passed to fractionator (14) in which it is split into a higher boiling fraction and a lower boiling fraction. The lower boiling fraction is collected and is free of mercaptans and retains high octane olefin content. The higher boiling fraction is hydrotreated (16) to remove sulfur and then sent to a shape-selective reactor to restore the octane loss.

Patent CA-2158270-A1 (CA)
Title: Method and apparatus for reducing self interference in a communication system
Inventor: KOTZIN MICHAEL D
IPC: G10L19/00
Filed: 1995-01-09
Abstract: A code division multiple access (CDMA) communicating system reduces interference by reducing the encoding rate for selected mobiles. The system (400) primarily uses link related characteristics such as, inter alia, distance measurements, physical resource power, and mobile determined noise, to determine which mobiles require an encoding rate reduction. Once determined, the encoding rate of the determined mobiles is reduced, which in turn reduces self-interference and enhances system capacity.

Title: Process for increasing the yield in the manufacture of titanium dixoide by the chloride process
Inventor: HARTMANN ACHIM
IPC: C22B34/12
Filed: 1995-11-14
Abstract: An improvement to the chloride process of making titanium dioxide. By recycling some of the cyclone dust, the yield in the chlorination of titanium-containing raw materials can be increased. In order to prevent silica accumulation in the fluidized bed, the cyclone dust is divided into two fractions. An economic solution is described of a single-stage separation of the cyclone dust in a hydrocyclone, the majority of the titanium dioxide occurring in the hydrocyclone underflow, although the separation is not sharp. By grinding the dried solids from the hydrocyclone underflow, the titanium dioxide particles returned to the lower region of the fluidized-bed reactor are rapidly chlorinated, while the quartz and coke particles are rapidly discharged again from the fluid bed, so that no silica contamination occurs.

Abstract: A spile accommodating plastic lid, having a transverse closure wall, for sealed closure of jars, bottles, pouches and like fluent material conveyances that must be accessed for issuance of material contained therein. The closure wall is provided with a circular breakout area having a frangible periphery thatfacilitates mounting of a hollow push-in-place spile onto the lid, wherein, tubular portion of the spile extends through the lid. The breakout area is constructed such that the frangible periphery yields and ruptures in a prescribed circular manner under push-in-place mounting of the spile. The breakout area is further constructed such that upon rupture of the frangible periphery it is pushed-through and inwardly hinged so as to establish a hole having an inwardly turned periphery which functions as a biased annular lip seal that sealingly embraces the extended tubular portion of the spile. Hinging of the breakout area is facilitated by the frangible periphery being interruptedwhereby a portion of the periphery is nonfrangible. The hole and the displaced breakout area remain linked by an unbroken span of plastic material that functions as a connecting hinge.

Patent CA-2178173-A1 (CA)
Title: Residential fuel oil level reporting device
Inventor: SHEA ARTHUR W
IPC: G01F23/62
Filed: 1996-06-04
Abstract: A remote level sensor for a residential fuel oil tank is adapted for a fuel oil gauge with a permanent magnet which changes position with changing fluid levels in the tank. The sensor has a housing with a connector which receives a top portion of the gauge such as to provide an alignment of the sensor with the gauge. The sensor is connected to a telephone line, and makes use of a current from the "tip" and "ring" lines of the telephone connection to supplement the power of an on-board battery. The sensor has multiple reed switches each in a different relative position. The reed switches thus each close when the magnet is in a different position, and thereby close when the fluid in the tank is at a different level. The controller has a sampling routine which responds to the detection of a closure of one of the switches by seizing the telephone line, dialing a central monitoring location and transmitting information to the central location indicating which of the switches was closed. A memory unit is provided in which multiple telephone numbers are stored so that the controller can call a second number when no response is received using a first number.

Title: Metallurgical furnace vacuum slag removal
Inventor: SHERWOOD WILLIAM LYON
IPC: F27D3/14
Filed: 1994-04-25
Abstract: A process and apparatus carries out the direct removal of slag (7) floating on the molten metal (6) within a metallurgical furnace via vacuum suction-tube (8) which is inserted from above through a furnace discharge opening (5). The tube discharge is connected into an evacuated external slag-cooling chamber (12), within which the slag stream exiting the suction-tube is granulated by impinging water jets (16). The water and entrained slag granules descend by gravity through a communicating water-column vacuum-leg (18), terminating in a atmosphere-exposed pool (22), within which the granules are collected on a conveyor (25) which dewaters the granules while carrying the slag out of the pool (22) to an external pile (28) or bin.  The invention is capable of realizing slow slag discharge at controlled rates over long time periods, as well as in conjunction with the simultaneous and continuous metal withdrawal by a somewhat analogous metal syphon tube (38) into an evacuated metal withdrawal chamber (37) for casting. It is particularly suited to discharge via the annular discharge opening from oxy-fuel fired rotary furnaces and the preferred embodiment includes effective means for closure and sealing of the discharge opening, concurrently with furnace heating and withdrawal of metal and slag. Appropriate means are also provided for positioning and supporting the vacuum chamber assemblies, also inserting and removing the slag and metal tubes, in a coordinated non-interfering manner.
