Patent CA-2390725-A1 (CA)
Title: Internal drive aerator for body of liquid
Inventor: SYLVESTER JACK BILL
IPC: B01F7/00
Filed: 2002-06-13
Abstract: An aerator or destratifier used to provide Oxygen to standing or less active bodies of water. The aerator has a non-floating internally driven motor within a non-floating sealed drum. The drum and motor are supported by a support frame attached to floatation devices. A plurality of elliptically shaped paddles are externally affixed to the exterior surface of the non-floating drum. Rotation of the drum by the internal motor and gearbox causes rotation of the plurality of paddles affixed to the drum exterior. The plurality of paddles cause agitation of the body of water and allow Oxygen to be dissolved therein.

Abstract: The invention relates to flexible straws [with one (or more) flexible zone consisting of folding rings] which are attached to the packaging of fruit juices, milks, coffees etc. and are bent to take up less space. The invention, by increasing the number of rings and keeping certain of the rings folded (1, 3, 4) succeeds in straightening the straw up again almost without any damage and in bending the straw to all directions. Further it increases the effective length of the straw. The advantage of the invention is that it attains complete straightening up and functionality of the straw without a significant increase in the production cost and without major changes in the current production line.

Title: Surface-mount antenna and communication device with surface-mount antenna
Inventor: NAGUMO SHOJI
IPC: H01Q5/10
Filed: 2000-09-08
Abstract: Power non-supplied side radiation electrode 3 and power supplied side radiation electrode 4 are formed on the surface of a dielectric substrate 2 with a space therebetween. A permittivity adjusting material portion 8 is provided in the space S which is situated between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and in which a capacity occurs. The permittivity adjusting material portion 8 has a lower permittivity than that of the dielectric substrate 2, which causes the permittivity between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4 to be lower than that of dielectric substrate 2, and weaken the capacitive coupling between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4. As a result, it becomes possible to suppress the mutual interference of the resonances of the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and to thereby improve antenna characteristics, without taking measures such as widening of the space S between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, or a reduction of the permittivity of the dielectric substrate 2, the measures hindering the surface-mounted type antenna 1 from miniaturization.

Patent CA-2431234-A1 (CA)
Inventor: ROTHENBERG JOSHUA E
IPC: G03F1/34
Filed: 2002-01-04
Abstract: The invention provides masks (200) that form fiber Bragg gratings (FBGs) in optical fibers without stitching errors from re-scaling or re-positioning. T he invention feathers the pixels of the mask lines (201, 202, 203) by adding, removing, and/or displacing one or more pixels (204, 205, 206) from the edge s of the bars and spaces of the mask. The feathering of pixels will affect the  FBG being written into the fiber. The feathering operates to shift the effective edge (207, 208) of the bars. This allows the achievement of much finer resolution FBGs than the pixel size of the mask.

Title: Electronic compass and compensation of large magnetic errors
Inventor: ELGERSMA MICHAEL R
IPC: G01C17/38
Filed: 2001-11-28
Abstract: A three-axis algebraic model is used to numerically compensate for magnetic errors in measured magnetic field values in an electronic compass for any orientation of the compass. This model is based on physical principles and uses a linear algebra approach that facilitates computation of the parameters needed for compensation. During a calibration procedure of the electronic compass, magnetic and gravity fields are measured in three axes at each of a variety of combinations of orientations and azimuths. This set of measured magnetic and gravity fields is used to calculate a matrix compensation coefficient and a vector compensation coefficient using a system of equations.  These compensation coefficients are stored and then used during normal operations of the electronic compass to correct all subsequently measured magnetometer data to obtain corrected values for the Earth's magnetic field, from which the correct azimuth can be calculated.

Abstract: A high-temperature burner is provided that is suited for the incineration of shredded plastics, tires, carpet or similar materials. The burner walls (10) are protected from the heat of the ongoing combustion reaction (90) by an annular curtain (85) of water vapor or carbon dioxide that takes the radiant heat energy of the high-temperature combustion reaction. The annular curtain removes the heat energy from the vicinity (12) of the burner walls before the energy can be conveyed to them. Higher temperature combustion can be attained without resorting to jacketed burner construction or the use of refractory materials.
