Patent CA-2174588-A1 (CA)
Title: Grate plate
Inventor: BOBBITT BILLY T
IPC: F27D15/02
Filed: 1996-04-19
Abstract: Improved grate plates are designed to produce multiple eddy currents in the absence of clinker and to provide even greater air distribution when overlaid by clinker. Each grate plate has a plurality of upwardly flaring wells which open to the upper surface on which the clinker bed is supported. Within each well is at least one semi-annular slot providing ingress for cooling air from a remote source. The slot extends only partially around the wall of the well such that air is injected into the well somewhat tangentially to the flaring surface to induce cyclonic motion of the air which is enhanced by the flared conic walls of the wells. Accordingly, the energy imparted the air by injection is diminished by the rotational energy dissipated and the cooling air's initial vertical component of velocity is diminished. Therefore, the vertical velocity of the cooling air through the bed is largely determined by the interstitial separation of the granular material and the heat absorbed by the air, with the initial vertical velocity playing only a minor role. The plates may be provided with removable plugs which can be used to close the airway through all or part of the wells of a grate to adjust the delivery of the air in gross over the width of the grate. Further, a dam may be provided such that the lowest level of clinker in the bed is stabilized and lateral air migration therethrough is facilitated.

Abstract: A digital receive filter comprises first and second filter parts with a down sampler between them. Each filter part is formed by a plurality of cascaded filter stages each comprising a second order finite impulse response digital filter having symmetrical coefficients which in most cases are integer powers of two, and in other cases are zero or a sum of integer powers of two. The filter stages are implemented by delay units and add units with shifting of bits at the inputs of the add units to implement the coefficients, whereby multipliers are avoided. A described receive filter has two filter stages in the first part, a down sampling factor of two, and seven filter stages in the second part, with scaling factors and ordering of the filter stages to facilitate filtering and minimize noise.
Patent CA-2178357-A1 (CA)
Title: High resolution viewing system
Inventor: NALWA VISHVJIT SINGH
IPC: G03B37/04
Filed: 1996-06-06
Abstract: A pyramid shaped (40) group of reflective surfaces (42) segment a field of view (82). Each of the reflective surfaces (42) of the pyramid (40) provides a segment of the field of view to a lens (62) which focuses the segment onto a sensor. The pyramid shaped collection of reflective surfaces provide each of the sensors with a common center of projection (120). This avoids distortions that may result from using sensors with differing centers of projection. The sensors provide an electronic representation of the image for storage or other uses. The sensor used to receive each segment may have a low resolution, but since the low resolution sensor is only capturing a segment of the image, the overall effect is to capture the entire image at a high resolution.

Patent CA-2188244-A1 (CA)
Inventor: COX JENNIFER
IPC: F24B1/187
Filed: 1996-10-18
Abstract: This invention discloses a filter-and-fan assembly that can be installed into new fireplaces or retrofitted into existing fireplaces, for filtering dust and smoke out of the hot exhaust gases that are created when wood is burned in fireplaces. This filter assembly is provided with a mechanism that can move the filter out of the flue channel (i.e., the chimney or other exhaust outlet) if the filter becomes clogged by creosote and/or smoke particles. If desired, the mechanism that moves the filter out of the flue path can be automated under the control of a device such as an electronic smoke detector mounted in front of the fireplace, above the fireplace opening. Alternately, a thin filter-paper type of filtering element can be continuously scrolled through the flue channel. A rotating fan blade can be provided directly above the filter element, to ensure that exhaust gases are actively drawn up through the filter. These means for avoiding blockage or hindrance of the flue channel can overcome a major obstacle that, until now, has completely blocked the development and adoption of smoke filters for conventional open-hearth fireplaces. This invention also discloses a convenient and clean method of opening and closing a fireplace damper without having to reach into a sooty fireplace, by inserting a solid damper plate (rather than a filter element) into a filter support bracket in a flue channel.
