Title: An improved pulverized coal burner
Inventor: KOSLOSKY JOHN V
IPC: F23K3/02
Filed: 1997-11-12
Abstract: A burner (40) having a transition zone (46) to act as a buffer between the primary zone (42) and the secondary zones (48, 50). The transition zone (46) allows improved control of near-burner mixing and flame stability by providing limited recirculation regions between the primary zone (42) and the secondary zones (48, 50). These limited recirculation regions transport evolved NO x back towards an oxygen-lean pyrolysis zone near the burner exit (52) for reduction to molecular nitrogen, thus decreasing emissions and unburned fuel losses.

Patent CA-2281371-A1 (CA)
Title: Rechargeable nickel-zinc cell
Inventor: TAUCHER-MAUTNER WALTRAUD
IPC: H01M4/66
Filed: 1999-09-03
Abstract: This invention is directed to fabrication of a rechargeable galvanic element with a positive nickel oxide electrode and a negative zinc electrode containing an alkaline electrolyte and a separator. The cathode consists of a nickel foam structure which is repeatedly filled with a nickel hydroxide rich paste made of a PVA-slurry. Then it is suitably compressed to a sheet or tape of defined thickness, rolled up into one or more layers and inserted into a nickel-plated steel can. In this way the nickel electrode is shaped into a very tight cylindrical cathode. Alternatively the filled foam can be compressed into a multiple of sleeves which are inserted exactly the same, also forming a cylindrical cathode. Such nickel foam based cathodes are exhibiting an exceptionally low resistance and high efficiency leading to a sharp cut-off after the capacity is completely exhausted thereby establishing a cathode limited cell. The anode consists of zinc powder, zinc oxide and a gelling agent, like Carbopol. In rechargeable nickel-zinc cells the anode capacity is chosen as a multiple of the cathode capacity. The separator is preferrably of the cellulosic type. A brass nail located in the center of the cell builds the negative terminal. The cell is characterized by prevention of excessive swelling of the cathode due to the cylindrical design in contrast to plate cells. It is further distinguished by the use of special additives to improve recharging. Recombination catalysts for hydrogen gas which may evolve as corrosion product from mercury-free zinc anodes are applied. The electrolyte is a solution of potassium hydroxide with lithium hydroxide as additive. The rechargeable nickel-zinc cells built according to the invention can be manufactured in all conventional cylindrical sizes (e.g. AAA, AA, C and D), hermetically sealed, and thereby used in all consumer electronic devices.

Patent CA-2282029-A1 (CA)
Title: Runflat tire
Inventor: MINER JENNIFER ANN
IPC: B60C1/00
Filed: 1999-09-08
Abstract: Runflat tires are generally made by including a stiff insert in the sidewall thereof. This insert should be as stiff as possible to help support the weight of the vehicle to which the tire is mounted in situations where there is a loss of air pressure.      However, the material used in making the insert should also exhibit low hysteresis and must be processable.      This highly beneficial combination of properties is attained by utilizing the compositions of this invention in making inserts of runflat tires. This invention discloses a runflat tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads; wherein said tread is adapted to be ground contacting, wherein said sidewalls contain at least one insert radially inward from said ply and wherein the insert is comprised of (1) a cured polydiene rubber that is coupled with a Group IVa metal selected from the group consisting of tin, lead, germanium and silicon, (2) from about 30 phr to about 130 phr of a filler and (3) from 0.1 phr to 5 phr of a fatty acid.      The insert will generally extend radially inward from under the outer circumferential tread toward the bead to which the sidewall extends. It is normally preferred for the cured polydiene rubber to be coupled with tin.

Several large coils are loaded on each rack and are transported to a tube finishing plant. The large coils are either unstacked from the racks or placed on a lowerable take-off table directly at the head of the tube finishing line, and the leading end of the coil is positioned at the working level. The coil is unwound, and then fed to a conventional drawing machine and processed further to tubes.

Patent CA-2301841-A1 (CA)
Title: Multichannel implantable cochlear stimulator
Inventor: STROJNIK PRIMOZ
IPC: A61N1/378
Filed: 1999-04-26
Abstract: An implantable cochlear stimulator (ICS) has eight output stages (212), each having a current source (212B) connected to a pair of electrodes, designated "A" and "B", through respective output coupling capacitors and an electrode switching matrix (212C). An indifferent electrode is connected to each output stage by way of an indifferent electrode switch (212D). The current source generates a precise stimulation current as a function of an analog control voltage. The analog control voltage, in turn, is generated by a logarithmic D/A converter. The D/A converter serially converts data words, received in a data frame from an external source, to respective analog control voltages that are applied sequentially to the current sources of each output stage. An output mode register (208) controls the switching matrix of each stage, as well as the indifferent electrode switch, to configure the electrodes for a desired stimulation configuration, e.g., bipolar stimulation (current flow between the pair of electrodes of the output stage), or monopolar stimulation (current flow between one of the electrodes of the output stage and the indifferent electrode). The voltage at the "A" and "B" electrode of each output stage may be selectively telemetered to the wearable system, as may the current flow through the indifferent electrode, thereby facilitating a measurement of the electrode impedance. The "A" and "B" electrodes of each output stage may be selectively shorted through a high or low resistance in order to discharge the output coupling capacitors.
