Title: Dual aspirator
Inventor: SPRIGGS JOHN R
IPC: B01F5/04
Filed: 1997-01-24
Abstract: A foaming system 10 includes a dual aspirator 13.      The dual aspirator 13 has first and second aspirators 80 and 81 to pick up a first and second chemical concentrate. The diluent first chemical mixture is drawn in through the first aspirator 80 and goes through a first diffuser 46 where the first chemical/diluent mixture is further mixed. Similarly, diluent/chemical mixture is drawn by the second aspirator 81 and flows through a second diffuser 47 where it also is mixed. The two diluent/chemical mixtures then combine after exiting the diffusers and the compatible chemicals are then mixed by the flow of the diluent/chemical mixtures. Flushing lines 68 and 71 provide for cleaning of the dual aspirator 13. Further, the diffusers have a ratio of their diameter to length to aid in the prevention of contamination along with the use of two check valves 48 and 49.
Patent CA-2196711-A1 (CA)
Title: Coring rod support wheel
Inventor: BROWN DAVID M
IPC: E21B7/20
Filed: 1997-02-04
Abstract: This invention relates to installing sections of horizontally laid underground piping using a coring rod to pull or push a coring knife horizontally through the site.   During tunnel diameter enlargment, when the coring knife is pushed into the exit pit, the coring rod and coring knife will fall to the exit pit's bottom. The invention is a coring rod support wheel that has a relatively large smooth outer surface and a hollow hub rigidly held within it. The axis of the hollow hub is parallel to the axis of the wheel, but not necessarily the same as the axis of the wheel. The diameter of the hub allows a coring rod to slide freely through it. Once the coring rod has been slid through the hub, the coring rod and any attached coring knife are supported and guided by the wheel to prevent them from falling to the exit pit's bottom, and to keep them on the correct path during tunnel diameter enlargment.

Title: Method and apparatus for eliminating television commercial messages
Inventor: IGGULDEN JERRY
IPC: H04H1/00
Filed: 1995-09-11
Abstract: A video recording and playback device (10) incorporates a processor (114) for processing the video signal to detect the presence of commercial messages.  Video and audio event detectors (102, 104) detect the presence of events in the signal as it is recorded. The timing relationship of the detected events is analyzed to classify the video segments between events as program material or as commercial messages. After a program is recorded, control marks are generated (132) to indicate the beginning and end of commercial groups so that they will be skipped during subsequent replay of the recorded program.

Patent CA-2201357-A1 (CA)
Inventor: MCCOWAN WILLIAM P
IPC: F02N19/04
Filed: 1995-09-28
Abstract: Cette invention se rapporte à un moteur à combustion interne à carburant diesel du type à pistons et à allumage par bougies, qui est équipé d'un système de conditionnement de charge comprenant un dispositif de préchauffage du carburant, destiné à effectuer la vaporisation du carburant liquide, pour permettre le démarrage du moteur, ainsi qu'au moins un dispositif de chauffage secondaire servant à ajouter de l'énergie thermique supplémentaire à la charge fournie au moteur. Le vaporisateur de carburant reçoit le carburant liquide provenant du circuit de carburant de départ du moteur et utilise un dispositif de chauffage actionné électriquement ou chimiquement ou un dispositif de chauffage à combustion directe. Le dispositif de chauffage secondaire peut être associé au conduit d'admission de charge du moteur ou à la chambre de combustion du moteur. Ce dispositif de chauffage secondaire peut être activé électriquement ou chimiquement ou il peut constituer un régénérateur thermique qui conserve la chaleur provenant d'un cycle de combustion antérieur du moteur. On évite l'encrassement des bougies d'allumage en utilisant des chambres secondaires qui sont adjacentes à la chambre de combustion du moteur et qui dirigent des jets en expansion de gaz haute vitesse en direction des électrodes des bougies d'allumage, à chaque cycle de combustion pendant la course de combustion-détente du piston.

Title: A method for internal communication in a telecommunications system
Inventor: OHLMAN BOERJE
IPC: G06F13/00
Filed: 1995-10-24
Abstract: In traffic processes in a telecommunication system there is internal communication between service controlling entities which may belong to logical nodes in the same or different applications (6, 8, 10). Such a service controlling entity may e.g. be a service process controlling a service for a party of a call. The communication between the service controlling entities is controlled by means of rules given in a generic protocol. These rules imply lack of messages and use only of protocol parameters in the form of indivisible information transmission elements. Based upon the generic protocol service protocols (ASP) are specified each corresponding to its service, a protocol managing entity (ASPE) within an application handling the protocol management of a certain service according to the service protocol (ASP). The information elements are distributed by a communication service (ITS) having a parameter distribution function for said parameters, by transferring data between the protocol managing entities (ASPE).

IPC: F16K11/00
Filed: 1995-10-17
Abstract: The present invention provides a fluid diverter valve (10) that allows quick connection/disconnection of a hand held sprayer used for cleaning shower stalls and bathrooms. The diverter valve (10) is comprised of a valve housing (20) having a water inlet (21), a first water outlet (22) where a standard shower may be attached, a second water outlet (23) and an annular cavity (24) therebetween; a valve runner (40) and an attachment housing (30) for constraining the valve runner (40) within the cavity (24). At the second outlet (23), the attachment housing (30) is fastened to the valve (10) for fluid communication. A spring (50) urges the valve runner (40) into a first position wherein the valve runner (40) seats adjacent the attachment housing, permitting fluid communication only between the inlet (21) and the first outlet (22). The attachment (90) of a flexible conduit (92) or a cleaning attachment system is coupled with the attachment housing (30), thus urging the valve runner (40) to a second position wherein the valve runner (40) seals the first outlet (22), permitting fluid communication only between the inlet (21) and the second outlet (23).

IPC: F15B21/04
Filed: 1997-05-21
Abstract: The invention in a safety bleed assembly includes a body wherein intersecting passages are formed that mount in ends thereof, respectively, a pressure gauge, and ports with check valves and ports alone. The ports with check valves function as high pressure ports and are for connection through lines or hoses to high pressure check/bleed connectors that have been mounted in lines or hoses of a section or sections of a hydraulic system that may remain under pressure after the hydraulic system has been shut down, and the ports without check valves function as low pressure ports that are for connection through lines or hoses to low pressure check/bleed connectors that have been mounted in lines or hoses of a section or sections of the hydraulic system that are at zero or low pressure when the hydraulic system has been shut down, with fluid passed through the safety bleed assembly of the invention to travel from high to low pressure ports. The high and low pressure ports, respectively, are each preferably color coded, as for example, red for high pressure and blue for low pressure, and sealing caps are provided for closing off the ports when a port is not connected to a line or hose that connects to a check/bleed connector.

Filed: 1996-02-06
Abstract: Dispositif capable de transmettre une puissance, de façon à augmenter graduellement cette puissance en fonction d'une différence de vitesse de rotation et d'un engrenage différentiel utilisant cette dernière. Quand une différence de vitesse de rotation apparaît entre une case (1) et un disque à billes (3), les billes (4) effectuent un mouvement de va-et-vient dans les rainures (1b) de la case (1) simultanément à leur roulement le long d'une rainure (3b) du disque à billes (3). Quand la différence entre les vitesses de rotation de la case (1) et du disque à billes (3) devient importante pendant cette période, la résistance apparaissant tandis que les billes (4) roulent contre un liquide visqueux, augmente et la puissance se transmet entre la case (1) et le disque à billes (3). Pendant cette période, la résistance du liquide visqueux (6) augmente en fonction de la vitesse de déplacement des billes (4), de sorte que la puissance transmise augmente progressivement en importance en fonction de la différence de vitesse de rotation.
