Patent CA-2129441-C (CA)

Abstract: A method of processing low grade lead-bearing materials where mostly simple and complex sulphates and oxides of metals are present, including higher iron oxides, such as for example, lead residues, dusts of matte converting and other similar materials. The starting material is mixed with fluxes, and powder sulphide and/or carboniferous material is inserted with a moisture content of resulting charge from about 2 to about 16%. The charge is dried, mixed with oxidized recycle dust, crushed carboniferous material and subjected to flash smelting in oxygen atmosphere. During smelting, the powder material reduces sulphate sulphur and higher iron oxides and, therefore a low melting oxide melt is produced and the crushed carboniferous material formes a heated bed under the torch of flame. Lead sulphate in this bed is reduced out of the melt and zinc stays in slag. Smelting off -gas is cleaned of oxidised dust which is returned to smelting. The following material is inserted to the charge as a powder material: either sulphide material (e.g. lead ore, low grade concentrate), which is added to the charge to obtain a mass ratio of the sum of sulphide, elemental and pyrite sulphur to a total sulphur content within the range from about 0.08 to about 0.87 or carboniferous material rated at about 4 to about 12 kg of uncombined carbon per 100 kg of ferric iron and from about 20 to about 140 kg of uncombined carbon per 100 kg of sulphate sulphur, or both materials are inserted at the same time in amounts indicated above

Abstract: Heavy metals are removed from waste lubricating oil by heating in the presence of an oxidation catalyst and a free radical initiator at temperatures in the range of about 150-200°C.  Corrosion and oxidation inhibitors previously added to the oil are thereby oxidized to form a separable sludge which contains the bulk of heavy metal contamination.  The process is of particular advantage in removing contaminating radioactive nuclides from lubricating oils used in nuclear generating facilities.

Title: Noise reduction in a switched reluctance motor by current profile manipulation
Inventor: HORST GARY E
IPC: H02K5/24
Filed: 1995-09-27
Granted: 1999-08-31
Abstract: Apparatus (10) for controlling the current profile (P2) in a single or polyphase SRM (M) during the active portion of a phase. Switches (S1, S2) are closed during an active portion of a phase to direct current flow into a winding (W).  A Hall effect sensor (14) and other sensors are used to sense various operating parameters of the SRM.  A PWM signal generator (16), or microprocessor (20) is responsive to the sensor inputs to provide PWM operating signals (G2) to at least one of the switches to control current flow to the winding.  The operating signals modulate the switch(es) for switch operation to be controlled as a function of the signal characteristics of the operating signals.          This allows the current supply to the winding to be in accordance with the current profile.  According to the profile, current flow is initially rapidly increased from zero to a peak value (Ip ') when the phase becomes active.  The current is then allowed to decrease from this peak to a second and lesser value (Ip) by the time the phase becomes inactive.  Current decays from this second value to zero when the phase becomes inactive.  The transition in the current profile which occurs when the phase switches from active to inactive is no longer an abrupt transition, but is rather a more moderate one.  This smoother transition reduces the amount of ringing in the motor, which normally occurs when current flow into the winding ceases, thereby to reduce motor noise.

Abstract: A low NOx, integrated boiler-burner cogeneration apparatus includes a horizontally fired, factory assembled package boiler having an inlet plenum and a furnace space. A gas turbine-generator having an outlet for providing turbine exhaust gas to the furnace space is connected to the boiler. A multi-nozzle burner (MNB) array including a plurality of vertically and horizontally spaced burner nozzles is located at an entrance to the furnace space for supplying fuel for combustion into the furnace space while distributing the heat of the combustion exhaust gases across the furnace space to minimize NOx formation. One or more chill tube assemblies are located within the furnace space immediately downstream of the MNB array for rapidly reducing the temperature of the combustion exhaust gases.  Laterally perforated internal duct assemblies can also be provided within the furnace space, alone or in combination with the chill tube assemblies in various arrangements to provide staging gases for completing combustion in the furnace space. A forced draft fan supplies combustion air alone or in combination with the turbine exhaust gases through the MNB array to mix with the fuel provided by the burner nozzles and produce the combustion flame.

Abstract: A sensor dispensing instrument is adapted to receive a generally circular sensor pack containing a plurality of blood glucose sensors. Each of the sensors are disposed in sensor cavities, each of which is in fluid communication with a corresponding desiccant cavity and has a support wall that assists in directing the sensor as its being ejected from the cavity. The sensor pack is loaded on an indexing disk in the instrument such that when a slide actuator on the instrument is moved toward a testing position, a feed mechanism engaged by the slide actuator moves a knife blade thereon toward one of the sensor cavities. The knife blade pierces a portion of a foil covering the sensor cavity and engages the sensor disposed in the cavity to thereby eject the sensor from the sensor cavity. The continued sliding of the slide actuator toward its testing position results in the sensor being completely ejected from the sensor cavity and disposed in a testing position with a testing end of the sensor projecting from the instrument. Once the blood analyzing test is completed, the slide actuator is moved in the opposite direction towards its standby position. As the slide actuator is moved away from its testing position, the indexing disk with the sensor pack thereon is rotated so that the next one of sensor cavities is positioned so that the sensor therein can be used for the next blood glucose test that is to be performed. The instrument includes circuitry to obtain test data from the sensor pack and to display testing data.
