Patent CA-2093601-A1 (CA)
Title: Premixed/high-velocity fuel jet low no x burner
Inventor: JOHNSON GREGORY L
IPC: F23C9/00
Filed: 1993-04-07
Abstract: The invention is a process for combusting a gaseous fuel in a burner to result in low NO x emissions by first feeding a gaseous fuel stream and an air stream to a premixer where the fuel and air streams are mixed to form a fuel-air mixture. The fuel and air streams are fed to the premixer at a fuel to air equivalence ratio of less than 1 (i.e., fuel-lean). Second, the fuel-air mixture is passed to a combustion chamber where the fuel is substantially combusted to produce a combustion chamber jet and flue gases. The combustion chamber jet and flue gases pass into a heating zone which may include a furnace, heater, or boiler. Third, at least two high-velocity fuel streams, optionally diluted with a non-reactive thermal ballast, are passed to the heating zone contemporaneously with the second step. The high-velocity fuel streams entrain at least a portion of the flue gases. The fuel in the high-velocity fuel streams is partially combusted prior to coming into contact with the combustion chamber jet. Last, the flue gases are removed from the heating zone.
Patent CA-2094150-A1 (CA)
Inventor: KUERZINGER KARL
IPC: B01D53/34
Filed: 1991-10-08
Abstract: 2094150 9206771 PCTABS00011 Described is a process for purifying flue gases with a high chloride content, in particular gases from domestic-waste and special waste incineration plants, by multi-stage absorption of the impurities, the strongly acid components of the flue gases, such as HCl and HF, being scrubbed out first with water and/or lye and the less acid components, such as  SO2 and NOx, being removed afterwards. The invention calls for flue dust, heavy metals and HF  to be separated out by quenching with water, while hydrogen chloride is converted, in at least two subsequent washing stages, into salt solutions.

Patent CA-2096995-A1 (CA)
Inventor: CHAN MAUREEN G
IPC: H01B7/02
Filed: 1993-05-26
Abstract: An insulated conductor (20) for use in a communication cable which includes a filling material (30) includes a copper conductor (25) and a composite insulation system (27) comprising two concentric layers of insulation. An inner foam layer (28) of the insulation comprises a cellular plastic material (28) which includes a stabilizer system . An outer layer (29) of the insulation is referred to as a skin and comprises a stabilized solid plastic material. The stabilizer system in each of the cellular and solid layers includes a bifunctional portion that functions as an antioxidant and as a metal deactivator and that has a relatively high resistance to extraction. The level of the bifunctional portion of the stabilizer in the cellular material is substantially greater than that in the skin inasmuch as it has been found that the level of the stabilizer cellular layer contiguous to the copper wire determines the oxidation performance level of the composite insulation.

Filed: 1993-06-10
Abstract: A heat and moisture exchange filter comprises a layer of hydrophobic media together with a layer of a hydrophilic media. The filter may be used in the medical field in open breathing systems with the hydrophilic material downstream of the patient in the exhalation path. The hydrophobic material prevents the passage of water droplets and globules in known manner and also has a bubble point sufficiently high to trap micro-organisms. The hydrophilic material captures water vapour that passes through the hydrophobic material thereby allowing more moisture to be retained by the filter. This moisture is picked up by the inhaled gases and serves to provide additional humidity for the inhaled gases.

Title: Envelope stop position finger and retraction apparatus for a thermal postage meter
Inventor: MISTYURIK JOHN D
IPC: G07B17/00
Filed: 1993-09-21
Abstract: ENVELOPE STOP POSITION FINGER AND RETRACTION APPARATUS       FOR A THERMAL POSTAGE METER                 Abstract of the Invention The positioning assembly is used in a thermal printing postage meter having a base supporting a registration wall and a deck, and a thermal print head fixably mounted to the registration wall above a portion of the deck to define a print station for printing a postage indicia on an envelope having a leading edge positioned on the deck in the print station.  The positioning assembly includes a stop lever and a position support arrangement. The position support arrangement provides support for the stop lever such that in a first or home position, the stop lever obstructs the longitudinal positioning on the deck beyond the proper print station location.  The obstruction is caused by encounter of the stop lever with the leading edge of the envelope.  During initiation of the print cycle, the stop lever is repositioned to a second position removing the stop lever from obstructing the leading edge of the envelope.

Abstract: Quick-disconnect couplings for three-piece rotors in a two-rotor continuous mixer for plastic materials enable a main rotor section (or "main rotor body") of each rotor to be uncoupled from a drive journal located at one end of the main rotor section and a driven journal located at the other end of the main rotor section. These quick-disconnect couplings as shown provide the following features: (a) piloted to maintain concentricity, (b) keyed to transmit torque, (c) enable quick assembly and disassembly of three-piece rotors, (d) maintain integrity of couplings bolted onto respective ends of each rotor section, (e) thus, a complete functional main rotor body is assembled with its quick-disconnect couplings at each end, (f) the disengageable interface between each coupling and each journal is supplied with both pilot and key, (g) concentricity and torque capabilities are built into the quick-disconnect coupling assemblies, (h) threaded locking collars captive on the journals serve to lock the disengageable interfaces together, (i) interface joints are pre-loaded by tightening the locking collars using spanner wrenches, (j) threaded locking collars do not become jammed, because torque is carried by keyed engagement at each interface, and (k) for disassembly the locking collars are backed off, and main rotor bodies together with their couplings are conveniently removed by separation at the piloted and keyed interfaces.

Date Jan. 20, 1994.For a squirrel-cage rotor of an electric machine, having a cage that passes through the stack axially and is made of electrically well-conductive short-circuit rods that are connected by short-circuit rings at the ends projecting from the stack, oscillation problems that result during operation with frequency converters are intended to be solved. In addition, higher natural torsion frequencies are intended to be achieved on the rotor, that is, the construction is to be made less sensitive by simple modifications to the squirrel cage in order to prevent the resonance effects. This object is attained in that respectively two, three or more short-circuit rods are guided together to rod assemblies at their ends, and these are connected to the short-circuit rings with material-to-material bonding.

Filed: 1994-03-10
Abstract: The invention relates to a water treatment system and more particularly to a fish tank and biofilter for use in a fish aquaculture. The fish tank has a double outlet system whereby solid waste particles are drawn continually into a central well by a trickle of water flowing through the well and out stand-pipe apparatus exterior of the tank. Clarified water is withdrawn from the center of the fish tank through a manifold having an outlet above the well and conducted to a spray bar of a separate biofilter apparatus. The biofilter includes a rotating spray bar distributing water over a bed of floating media pellets, the water exiting the spray bar causing momentarily and cyclically dynamic flow loading of the bed of pellets below it whereby the pellets are gently agitated. Fine particles in the clarified water to be filtered and biofilter growth particulates gently scoured from the media fall to a cone-shaped bottom of the biofilter tank and gravitate to a central well from which the solid fine wastes can be periodically flushed. The filtered water is returned to the fish tank by a filtered water manifold having an inlet above the bottom of the biofilter tank but below the floating media.
