Patent CA-2125091-A1 (CA)
Title: Inducer for Condensing Furnace
Inventor: CHOU RUDY S
IPC: F24H3/06
Filed: 1994-06-03
Abstract: An inducer for causing a flow of combustion air into and gases of combustion through and out of a furnace of the condensing type.  The inducer is intended for use, without modification of its design or size, in a series of furnaces of  the  same basic design but having different  heating capacities and therefore different requirements for flow through the induction flow path.   The furnace design is such that a given furnace is capable of operation so as to provide a flow of air to be heated that is either up, down or  horizontal  with  only  minor  field  modification  on installation.  The inducer has two discharges, only one of which is used in a given installation.  The other discharge is blocked with a plug of special configuration that can vary the output of the inducer to ensure optimum flow of combustion air into and gases of combustion through and out of the furnace.  The inducer configuration is such that, in every possible orientation of the furnace installation, at least one of its two drains is at the low point of the inducer housing so that all condensate that collects in the housing can flow to a low point drain regardless of the orientation of the furnace.

Title: A method and device for producing panoramic images, and a method and device for consulting panoramic images
Inventor: POELSTRA THEO JOGCHUM
IPC: H04N5/225
Filed: 1993-11-24
Abstract: A method for producing panorama images whereby a shot is made from a desired shooting position with the help of a camera with a fish eye optic whereafter the obtained image is scanned and then the digital images are transformed into a panoramic image with the help of a computer and software. The digital image is scanned by dividing the image up into narrow radial segments. Each radial segment, in the radial direction, is then divided up into a number of parts of equal height whereafter each segment part obtained is depicted on a point of a straight line, whereby the grey tint of each segment part is corrected for the modified surface on which it is depicted. The invention also concerns an apparatus which comprises a camera provided with a fish eye optic. The image area is provided with a CCD-metric an which the image obtained is projected, whereby an image in digital form is immediately obtained.

Title: Process for applying a coating to honeycomb structures in an exhaust gas converter
Inventor: DOMESLE RAINER
IPC: B01J35/04
Filed: 1995-03-16
Abstract: The invention relates to a process for applying a coating to honeycomb structures in an exhaust gas converter which contains two such honeycomb structures in a common housing or enveloping tube which are arranged one after the other and which are separated from each other by a gap.          According to the invention, the coating dispersion is first supplied from one end of the exhaust gas converter up to the gap between the two honeycomb structures.  Then excess coating dispersion is driven out using a blast of air from the direction of the uncoated honeycomb structure.  To coat the second honeycomb structure, the exhaust gas converter is inverted and the coating dispersion is then applied in the same way but from the uncoated end.  Following the dispersion coating procedure, production of the catalyst is completed by drying and optionally calcining.

Title: Method and pulp washing machine for washing pulp or similar material
Inventor: SAALASTI TIMO TAPIO
IPC: D21C9/06
Filed: 1993-11-05
Abstract: The pulp to be washed is fed between the rotating drum (1) and the pressing roll (2) inside it, so that pulp passes along a spiral-formed track around the pressing roll (2), being thereby pressed several times. Washing li-quid (7) is fed to the pulp at one or several points along its track of movement, between the pressings and/or at the pressing position. Washing thus takes place partly as a diffusion and partly as a displacement washing process. Washing is efficient and brings the breaking of pulp fibers down to a minimum.
