Patent CA-2313048-A1 (CA)
Title: Apparatus and method for constant flow oxidizing of organic materials
Inventor: STEWARD G ANTHONY
IPC: C25B3/23
Filed: 1998-12-02
Abstract: The invention comprises a method and apparatus using high cerium concentration in the anolyte of an electrochemical cell (100) to oxidize a treatment mixture of an organic phase in an aqueous solution. Acidic anolyte comprising cerium in an original oxidant state is emulsified together with the organic material in an ultrasonic mixer (114). This reaction mixture is passed to a reactor tank (700) wherein the organic material reacts with the anolyte destroying the organic material and reducing the oxidant in the anolyte. A portion of the anolyte goes to the electrochemical cell (100) and is oxidized and regenerated before it passes back into the anolyte tank (112). The reaction vessel (700) provides an advantage of independent reaction temperature control and electrochemical cell temperature control.
Patent CA-2313505-A1 (CA)
Title: Extruder head
Inventor: KAPPEN GUNTHER
IPC: B29C48/09
Filed: 2000-07-10
Abstract: An extruder head for extrusion blow-molding plastic containers includes a ring gap nozzle with a mandrel and a ring-shaped nozzle body. An elastically deformable sleeve is arranged on an end of the nozzle outlet side and defines a gap width which can be varied by axial setting movements of the mandrel and/or the nozzle body. The geometry of the nozzle gap can be influenced by radially deforming the sleeve with setting devices during the extrusion of a hose-shaped preformed blank. The sleeve may be moved in a radial direction and is guided on sliding surfaces which support it in upward and downward directions. The sleeve may be in the form of a cylinder or tube. A lower edge of the sleeve shapes a cross-section of a melt stream exiting from the ring gap nozzle.

Patent CA-2320272-A1 (CA)
Title: Gas burner
Inventor: SZUCS FRANK T JR
IPC: F24C3/00
Filed: 1998-03-05
Abstract: A gas burner that produces a yellow flame for use in a fireplace assembly, including front and rear non-combustible logs and a cross-over log supported atop the front and rear logs. The burner includes an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element and to define at least one primary air opening arranged to admit combustion air into the tubular burner segment. A bluff body is located downstream from the gas orifice element and is positioned such that gas emitted by the orifice impinges on the bluff body. Rows of slot-like flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern and include tabs which determine the effective size of the ports. In regions of the burner located below the crossover log, flame ports are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting. In alternate embodiments, the bluff body is formed by a pair of confronting depressions that define a pair of venturi channels which define the mixing chamber. In another embodiment, the confronting depressions are spaced apart and mount a cylindrical bluff element therebetween. The use of venturi channels eliminates or substantially reduces the incidence of light back.

Title: Process for detecting, and monitoring changes in properties of fluidized bed solids by measurement of pressure difference fluctuation
Inventor: SHABAKER ROBERT H
IPC: C01B3/38
Filed: 2000-01-14
Abstract: A process for detecting, and monitoring, changes in the properties of a fluidized bed of particulate solids, especially a fluidized bed of particulate catalytic solids at elevated temperature wherein a low molecular weight hydrocarbon is converted, in the presence of steam and oxygen, to synthesis gas. Measurement is made of the magnitude of differential pressure fluctuations taken at different levels of bed elevation and these are recorded as a standard deviation, or normalized standard deviation, and directly related to particle size changes caused by agglomeration (growth) and/or attrition (size reduction). Operation of the process requires the use of fast response pressure transducers that are located in the bed and connected to an A/D board of a PC which records and accumulates the data for processing, and analysis. In a preferred process, the method is applied to the fluidized bed production of synthesis gas.
