Patent CA-2187745-A1 (CA)
Title: V-jet atomizer
Inventor: HERSH STUART
IPC: F23D11/10
Filed: 1994-09-09
Abstract: A fluid atomizer and spraying means which is made up of a mixing chamber (16) into which the fluid to be atomized and the atomizing gas are introduced and in which the fluid is admixed with and dispersed in the gas; a generally conical nozzle means extending from the mixing chamber (16) through which the mixed fluid and gas are forced; and a chamber into which the atomized mixed fluid and gas is sprayed. The conical nozzle means is suitably a relatively narrow frusto-conical passageway (28) which contains support-spacer means (34, 36, 38) which is generally parallel to the direction of flow through the passageway (28). At least one such support-spacer means (34, 36, 38) is provided which extends from the end of the passageway (28) proximate to the mixing chamber (16) to the end of the passageway (28) proximate to the chamber into which the mixture is sprayed. The preferred use of this apparatus is in atomizing fuel oil with steam and spraying such atomized mixture into a combustion chamber where it is contacted with combustion air. The amount of effluent NOX is reduced and limited by the use of this configuration by creating alternating fuel-rich and air-rich spatial distribution, and allowing the amount of stoichiometric excess air to be severely limited, while causing the substantially complete combustion of the fuel oil
Patent CA-2195044-A1 (CA)
Inventor: BANERJEE CHANDRA KUMAR
IPC: B01D39/18
Filed: 1997-01-14
Abstract: A cigarette smoking article achieves very low levels of CO and other gas phase components by means of substantial air dilution, but has an acceptable pressure drop and sufficient delivery of particulate matter to provide a flavorful smoke. The filter has two sections, an upstream section which has substantially no pressure drop thereacross and a downstream section which provides substantially all the pressure drop of the filter. Dilution air is admitted to the upstream section of the filter to mix with mainstream smoke before it passes through the downstream section of the filter and thereby reduce the CO and gas phase levels in the smoke.
Patent CA-2195882-A1 (CA)
Inventor: ARSALIDES ELIAS
IPC: A63C17/22
Filed: 1997-01-24
Abstract: The product has initial application to all inline roller blade wheel skates.  The purpose of the product is to improve the performance of the wheels on inline roller blade skates by providing a suspension system within the wheel thus allowing the wheel to roll over small obstacles in a smooth fashion with the result that the ride will be smooth and the likelihood of injury to an individuals lower spine, knees and ankles will be greatly reduce.        The wheel contains within it an internal spring suspension mechanism, which permits the wheel to rise or fall as the case may be over an obstacle.   There are two outer guiding pins contained within the wheel that guide the central travelling system upwards or downwards based upon pressure exerted by the wheel against the internal spring suspension mechanism.   The system has a central pin that allows the same to always be in an upright position to the surface travelled over when the roller wheel is in motion.

Title: Screen of the type having two or more overlapping sliding leaves
Inventor: DUFFY PHILIP
IPC: A47K3/34
Filed: 1995-08-17
Abstract: A screen (10) comprises overlapping leaves (12.1, 12.2), an upper rail (14.1) on which the leaves are hung, and a lower rail (14.2) for guiding the lower ends of the leaves during their sliding movement. A runner element (30) whereby the lower end of an outer one of the leaves is guided with respect to the lower rail, is pivotally displaceable between a first condition in which it engages with the lower rail and a second condition in which it is disengaged from the lower rail, permitting the leaf to swing away from the other leaf. This facilitates cleaning of the leaves in the region where they overlap.

Title: Method and apparatus for determining the configuration of a workpiece
Inventor: GILLILAND MALCOLM T
IPC: G06T7/00
Filed: 1997-04-08
Abstract: The present invention provides a method and an apparatus for scanning an object to obtain data on the object and determine the configuration of the object. A gantry (12) allows movement along a first direction (A-A'). A set of platforms (14A, 14B) allows movement along a second direction (B-B'). A set of scanning heads (16A, 16B) provide additional degrees of freedom and also provide for scanning the object (10) to obtain information about the object. The freedom of movement provided by the gantry, the platforms, and the scanning heads allows the object to be completely scanned. In addition, once the initial scanning process has been completely, areas which require additional scanning, such as compartments (10D), are identified. The scanning heads are then positioned, such as directly above or inside a compartment, and then the compartment is scanned to obtain information about the compartment that could not be obtained from the initial scanning procedure. The data obtained from the initial scan and any subsequent scans is processed to determine the configuration of the object. The information concerning the configuration is then used to perform a welding, cutting or other operation on the object.

Patent CA-2224786-A1 (CA)
Title: Method and device for transmitting additional data in television channels
Inventor: POEGEL FRANK
IPC: H04N7/088
Filed: 1996-06-14
Abstract: In the terrestrial transmission network infrastructure, test lines and videotext are already carried mainly in the picture-free lines. Additional wireless services often fail as a result of the high cost of television studios and a shortage of frequencies. The present invention accordingly aims to make even fuller use of unused channel capacity in a TV channel for additional signals. At both the transmission and receiving ends, the signal pulses for additional video and audio data to be transmitted are formed from the FBAS useful signal by counting, evaluation and decision operations. The two signals are separated, digitised, stored, buffered and compressed at the transmission end before being superimposed on the useful signal.      At the receiving end, following identical signal pulse generation, the same steps are executed in reverse order. The procedure can be carried out at the transmission end using additional equipment and at the receiving end by computer software or additional devices installed in the TV set. The procedure can be used for any additional picture and sound signals. A preferred special application is a communal picture broadcast in the manner of a slide demonstration.
