Patent CA-2251768-C (CA)
Inventor: BLAZEJEWSKI EDWARD G
IPC: F28D17/00

Abstract: Regenerative thermal oxidizer in which a gas such as contaminated air is first passed through a hot heat-exchange bed and into a communicating high temperature oxidation (combustion) chamber, and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns topped by an internally insulated combustion chamber. Process air is fed into the oxidizer through an inlet manifold containing a number of hydraulically or pneumatically operated flow control valves (such as poppet valves). The air is then directed into the heat exchange media which contains "stored" heat from the previous recovery cycle. The process air is heated to near oxidation temperatures. Oxidation is completed as the flow passes through the combustion chamber, where one or more burners are located. The gas is maintained at the operating temperature for an amount of time sufficient for completing destruction of the VOC's. From the combustion chamber, the gas flows vertically downward through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. The resulting clean air is directed via an outlet valve through an outlet manifold and released to atmosphere at a slightly higher temperature than inlet, or is recirculated back to the oxidizer inlet. An integrated VOC entrapment chamber entraps any VOC's that leak out during cycling, and recycles them back to the oxidizer inlet for further processing.

Abstract: The invention relates to a device for transporting flat, especially plate-like, objects (2, 2') with a driven conveyor belt (4, 4') running around a conveyor belt body (3, 3') and on which the objects (2, 2') bear during transport. Said conveyor belt has suction apertures to which a vacuum from a vacuum system can be applied, is to be further developed in such a way that it is possible to convey suspended or supported magnetic and non-magnetic flat, especially plate-like objects at high speeds and considerable acceleration. This is achieved in that the vacuum system is integrated into at least one combined vacuum-magnet system (VMS) which is fitted in the conveyor belt body (3, 3') and its action is applied to the region of the conveyor belt (4,4') bearing the objects (2,2'). Each vacuum- magnet system (VMS) has at least one magnet (5, 5') and one vacuum channel (6,6') connected to a vacuum source (4,4') close to the conveyor belt (4,4'), which is connected to the suction apertures in the conveyor belt (4,4') via suction pipes (7,7') passing through the magnets (5,5').

Abstract: A combined temperature and pressure sensing probe assembly for a flow measurement system (2) comprising, a tubular body (4), a portion of which is adapted for insertion into fluid flowing in a confined conduit, such as a pipe (6). Within the tubular body are separated plenums which are exposed respectively to high and low fluid pressures in the flow. A manifold block (10) is attached to that portion of the tubular body which is disposed outside of the pipe containing the fluid flow. Along with valves (20) and fluid conveying channels, the block is equipped with a duct for carrying electrical conductors and also contains a traverse bore which is aligned with the tubular body and is in communications with the conductor carrying duct. An electrically responsive temperature sensor (32) is disposed within the tubular body and is mounted in the aligned bore of the manifold. Conductors (30) from the temperature sensor (32) are directed from the manifold's bore (35) through the connecting duet to a point exterior of the manifold.

Title: Call control method
Inventor: VERKAMA MARKKU
IPC: H04M15/00
Filed: 1998-02-26
Granted: 2007-01-09
Abstract: In some mobile telecommunications systems reception of calls outside the home network may be very expensive for the called subscriber. For this reason, subscribers are given the possibility to bar incoming calls when roaming outside the home network. On the other hand, when using optimised routing, reception of calls even far from the home network may be very advantageous or even free. Hereby there are no longer any grounds for barring incoming calls. A method is presented in this invention where those network elements can be defined for the subscriber on a location information basis from which incoming calls will be relayed to the subscriber.

Abstract: A system for suspending a ceiling fan is provided which allows the ceiling fan to pivot, to accommodate vaulted or sloped ceilings, while preventing the ceiling fan from rotating about a longitudinal centerline axis of the fan. The system includes a hollow canopy defining an interior space and having an upper end portion, which is operatively attachable to a support structure such as the ceiling. The canopy further includes a lower end portion and a central, body portion extending between the upper and lower end portions. The canopy includes a seat which is connected to and extends upwardly from the lower end portion, and a guide which is also connected to the lower end portion and extends upwardly therefrom. The guide has an inner surface which forms a portion of the inner surface of the seat and defines a receptacle which extends through the seat and a bottom surface of the canopy. The seat defines an aperture which also extends through the bottom surface of the canopy. A ball is pivotally engaged with the canopy seat and is connected to a stationary portion of the ceiling fan. A pin is attached to the ball and protrudes radially outwardly from the outer surface of the ball, with the pin being engaged in the receptacle of the canopy guide. The pin has a longitudinal centerline axis which extends through a center of the outer surface of the ball and is substantially perpendicular to the longitudinal centerline axis of the ceiling fan. The ball and ceiling fan pivot about the centerline axis of the pin. The system may also include a hollow sleeve connected to the stationary portion of the ceiling fan, such as an upper end portion of a downrod of the ceiling fan. In this instance, the ball is disposed in surrounding relationship with the hollow sleeve and frictionally engages the sleeve.

Granted: 2005-02-15
Abstract: Disclosed is a composition for coloring a non-meat protein containing material. The composition includes a thermally unstable pigment and a browning agent. The thermally unstable pigment is effective to provide a color to a protein containing material resembling a color substantially present in a browning meat only in an uncooked state. The thermally unstable pigment has a structure which undergoes degradation upon exposure to temperatures effective to cook a protein containing material. The degraded thermally unstable pigment is ineffective to provide substantial coloration to a protein containing material. The browning agent is effective to provide a brown color to a protein containing material upon exposure to temperatures effective to cook a protein containing material. The browning agent enables a protein containing material to which it is added to brown in a manner similar to a browning meat when the protein containing material is cooked.
