Patent CA-2250636-A1 (CA)
Title: Combustion apparatus
Inventor: GENGO TADASHI
IPC: F23C5/00
Filed: 1998-10-16
Abstract: An object of the present invention is to provide a combustion apparatus in which a space which does not contribute effectively to the combustion of fuel is less prone to be produced in a furnace because burners are not disposed at the corners of the furnace.      The furnace having a square horizontal cross section is provided with the burners so that an in-furnace injection direction axis line of the burner is tangent to an imaginary circle. The burner is disposed at one place on a front wall, rear wall, right side wall, and left side wall of the furnace each, at a total of four places. The burner on each wall is installed so that the intersection of the in-furnace injection direction axis line of the burner and the furnace wall surface is apart from a furnace corner (corner point) by a length L1. The value of the length L1 is 15% of a length L of one side of width of the inside wall of the furnace when the furnace is viewed from the top.

Title: Apparatus and method for burning organic material
Inventor: KIMBERLIN JOHN
IPC: F23G7/10
Filed: 1997-04-02
Abstract: An apparatus and method for burning organic material including farm bedding waste of the present invention includes a firebox (14) having an air injector (22) disposed within the firebox (14). A heat exchanger (20) is also disposed within the firebox (14) above the air injector (22). The fuel (18) to be burned, a mixture of organic farm bedding waste, is piled in the firebox (14) surrounding the air injector (22) and heat exchanger (20). By injecting air into the pile of fuel, the fuel is burned from the inside out, surrounding the heat exchanger (20) with the burning fuel. The unburned fuel acts to insulate the burning fuel from the walls of the firebox (14). The apparatus can be used as an incinerator, a furnace to heat a building, or any other use requiring the generaton of heat.
Patent CA-2251378-A1 (CA)
Title: High-speed and high-precision phase locked loop
Inventor: JEONG DEOG-KYOON
IPC: H03K5/26
Filed: 1997-04-04
Abstract: A phase lock loop includes a charge pump, a voltage controlled oscillator (VCO), and a phase frequency detector. The phase frequency detector has a dynamic logic structure. The phase frequency detector generates up and down signals for directing the charge pump to provide a voltage signal to the VCO to vary the frequency of the VCO clock.  The difference between the up and down signals is indicative of the phase difference between the reference signal and the VCO clock. The phase frequency detector includes up and down signal generators for generating the up and down signals, respectively.

Title: Apparatus and method for determining axial stability
Inventor: JACKSON DAVID
IPC: G01B11/275
Filed: 1998-11-04
Abstract: An apparatus and method for determining axial stability compares measured wheel runout and axial instability parameters with prescribed tolerances to determine if the wheel (101) suffers from excessive wheel play.       Axial stability and runout are determined and displayed on a monitor screen (110) such that an alignment technician can quickly assess both the degree of present wheel misalignment and the feasibility of attempting to perform a realignment operation without first repairing worn or damaged suspension parts. The attitude and location of a wheel are measured with the wheel set in a first position (position 1 ) to determine a first vector having a predetermined relation to the wheel. The wheel is rolled back a number of degrees to a second position (position 2) and the attitude and location thereof are measured to determine a second vector also having the predetermined relation to the wheel.       Rearward axis parameters including a rearward rotational axis vector and a rearward runout vector are determined based on the first and second vectors. The wheel is rolled forward to a third position (position 3) which is substantially equal to the first position and the attitude and location of the wheel are measured to determine a third vector also having the predetermined relation to the wheel. Forward axis parameters including a forward rotational axis vector and a forward runout vector, are determined based on the second and third vectors. Dynamic stability vectors including a rotational axis stability vector and a runout stability vector are determined based on the forward and rearward axis parameters.

Title: High-frequency circuit device and communication apparatus having spurious mode propagation blocking circuit
Inventor: KATO TAKATOSHI
IPC: H01P5/18
Filed: 1999-07-22
Abstract: Electrodes are formed on both top and bottom surfaces of a dielectric plate and grounded coplanar lines, as transmission lines, are formed on the top surface of the dielectric plate. A plurality of micro-strip lines, each composed of high-impedance lines and low-impedance lines alternately connected in series, is arranged at a pitch shorter than the wavelength of a wave traveling along the grounded coplanar lines. A spurious mode propagation blocking circuit thus constructed prevents a spurious mode wave, such as a parallel-plate mode, from traveling.

Title: Polyolefin products and process additives therefor having reduced transfer to substrates
Inventor: RAMESH NATARAJAN S
IPC: C08K5/20
Filed: 1998-03-26
Abstract: A process additive for polyolefin films and foams produces products having reduced greasiness and reduced grease-like transfer as compared to glycerol monostearate (GMS). The process additive comprises a fatty acid N-aliphatic alcohol amide of the general formula R-CON(R')R". R is a fatty hydrocarbon radical having from about 8 to 30 carbons. R' typically is hydrogen. R' can also be an alkyl radical of from about 1 to 6 carbons or an alkyl alcohol radical of from about 1 to 6 carbons. R" is an alkyl alcohol fragment of from about 1 to 6 carbons. The alkyl alcohol fragments can be monohydric or polyhydric. Secondary fatty monoalkanolamides in which R' is hydrogen are particularly useful, especially stearamide monoethanolamine (MEA). The benefits of the invention can be achieved and enhanced in some examples by mixing the fatty acid N-aliphatic alcohol amide with an ester of a long chain fatty acid with a polyhydric alcohol, including GMS. Examples of fatty acid Naliphatic alcohol amides include cocamide MEA, lauramide monoisopropylamine (MIPA), oleamide MIPA, and stearamide 2,3-propanediol.

Title: Reducing nox emissions from an engine by temperature-controlled urea injection
Inventor: PETER-HOBLYN JEREMY D
IPC: B01D53/90
Filed: 1998-03-31
Abstract: A safe, reliable SCR system for reducing NO x emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. Overheating and hydrolysis of the solution are prevented by maintaining the temperature of the urea solution sufficiently low that it is not permitted sufficient time at elevated temperature to hydrolyze the urea to such an extent that solids precipitate. In a preferred embodiment, an injector system similar to those used for fuel injection provides a constant feed to injectors (32) and a return line (33). The feed and injection can be controlled to provide sufficient urea for NO x reduction and sufficient cooling capacity for the feed and injection system to avoid hydrolysis and deposits of hydrolysis products.

Patent CA-2296180-A1 (CA)
Title: Thermal protection apparatus for electric motors
Inventor: BERFIELD ROBERT C
IPC: H02K5/14
Filed: 2000-01-17
Abstract: A thermal protection mechanism for electric motors is disclosed. A brush is urged into electrical contact with a commutator by a primary brush spring. A thermally deformable fastener releasably secures the primary brush spring to a brush housing. A secondary brush spring urges the brush away from the commutator with a force less than that of the primary spring. A thermal overload condition within the motor causes the thermally deformable fastener to substantially deform so that the force exerted on the brush by the primary spring is substantially reduced. The force exerted by the secondary spring overcomes the primary spring so that the brush is forcefully disengaged from electrical contact with the commutator, thereby terminating operation of the motor.
