Patent CA-2706884-A1 (CA)
Inventor: WALDO COLE L
IPC: B01D41/04
Filed: 2008-08-27
Abstract: An apparatus for pneumatic cleaning of diesel particulate filters (DPF). First and second nozzle members direct flows of compressed air into the axially-extending filter cells from both ends of the filter, the nozzle members generally being offset so as to avoid blowing directly towards one another. The flows form the nozzles impinge only relatively small areas of the end faces of the filter media, e.g., only one or a few cells at a time. The nozzle members are moved over substantially the entirety of the first and second end faces, so that as cleaning progresses compressed air is directed into substantially all of the filter cells from opposite directions. The nozzles may be translated on reciprocated arms while the filter is rotated simultaneously on a turntable or rollers, so that the nozzles sweep over the whole surface of each end; other mechanisms, such as various combinations of gears or pistons, may be used for relative movement between the nozzles and filters. Also, the nozzle members may have single or multiple nozzles. The filter and nozzles are housed within a cabinet having one or more windows therein, which enable an operator to view progress of the cleaning process and determine when it is complete. Visual observation and also enables an operator to identify filters having damaged media, as indicated by particulate material billowing from both ends of the filter due to cracked or broke axial cells. The dislodged particulate material is withdrawn from the cabinet by an exhaust duct system.

Title: Methods and compositions for treating conditions of the eye
Inventor: MILLER JOAN W
IPC: A61K47/48
Filed: 2001-02-09
Abstract: Provided are methods and compositions for the photodynamic therapy (PDT) of ocular conditions characterized by the presence of unwanted choroidal neovasculature, for example, neovascular age-related macular degeneration. The selectivity and sensitivity of the PDT method can be enhanced by combining the PDT with an anti-angiogenesis factor, for example, angiostatin or endostatin, or with an apoptosis-modulating factor.  Furthermore, the selectivity and sensitivity of the PDT may be further enhanced by coupling a targeting moiety to the photosensitizer so as to target the photosensitizer to choroidal neovasculature.
Patent CA-2717385-A1 (CA)
Inventor: OLVERA DIAZ LUIS
IPC: F03B17/00
Filed: 2008-02-25
Abstract: The invention relates to a pressure generator and to the novel features thereof, which is intended to multiply pressure output through the use of sealed chambers containing rodless pistons acting on the fluid which operates as a force transmitter and concentrates the force on the frusto-conical covers at each end of the piston. Owing to the taper of the covers, the force is directed towards the directional valves which are housed in the ends of the piston and distribute the pressure in an ordered manner through fluid conductors towards the hydraulic motor. The operation and novel features of said generator render these systems more efficient.

IPC: H02H3/00
Filed: 2009-09-18
Abstract: An intelligent electronic device (IED) may be configured to detect arc flash events within a power system using stimulus measurements acquired by detection devices communicatively coupled to the power system. An arc flash event may be detected using a time-intensity comparison metric, such as an inverse time-over- stimulus metric, a cumulative stimulus metric, or the like. The stimulus may include electro-optical (EO) radiation produced in the vicinity of the power system, current measurements, or the like. The IED may detect an arc flash event if one or more of the stimulus types are indicative of an arc flash event. Responsive to detecting an arc flash event, the IED, or other protective element, may take one or more protective actions, such as issuing trip commands, or the like.

Abstract: A wireless audio signal transmitter is presented that routes audio signals to either a wired or a wireless sound output device. The transmitter selects whether the audio signal is transmitted over a wireless antenna to a wireless device, or is transmitted to a physically attached device. The transmitter may take the form of a USB dongle or a wireless device charging station. The transmitter detects whether the wireless audio output device is powered on and in communication with the transmitter to determine how to route the audio signal received from the computer. If the wireless audio output device is connected to the transmitter, the audio signal is routed to the wireless audio output device. If there is no connection, then the audio signal is routed to the wired audio output device.

Abstract: Apparatus for separating grit from liquid sewage while retaining organic solids in suspension. The apparatus includes a grit settling chamber, a grit storage chamber positioned below the settling chamber, and a rotating vertical shaft positioned centrally in the settling chamber. A propeller is rotatably mounted around the shaft. A conical partition extends transversely through an intermediate section of the settling chamber. Liquid sewage engages the lower part of settling chamber beneath the conical partition, and liquid separated from grit escapes from the upper part of settling-chamber above conical partition. The partition has a peripheral edge integrally mounted in fluid tight fashion to the peripheral wall of the settling chamber, and defines a central annular opening between the shaft and the partition to provide for upward flow of liquid from the lower subchamber to the upper subchamber. The propeller enables sustained rotational liquid sewage first fluid flow within the lower subchamber, inducing upward liquid second fluid flow from the lower subchamber through the partition annular opening and into the upper subchamber, and enables sustained rotational liquid third fluid flow within the upper subchamber for tangential or radial escape therefrom, wherein a fluid flow speed gradient is established between the third fluid flow and the first fluid flow.

Title: Transfer device
Inventor: UTTECH SCOTT K
IPC: A61G3/00
Filed: 2010-02-02
Abstract: A transfer device to assist a user in moving between vertically displaced locations has a storage enclosure mounted or mountable to the exterior of a motor vehicle. The storage enclosure protects components from external conditions, weather, etc., and typically is made of steel, plastic, etc. A user platform is supported on a drawer assembly that can be completely encased in the storage enclosure. Movement of the drawer assembly is controlled by a drawer extension mechanism that selectively extends and retracts the drawer assembly into and out of the storage enclosure between a stored position completely inside the storage enclosure and an operative position outside the storage enclosure.  When the drawer assembly is in an operative position outside the storage enclosure, a platform elevating mechanism can raise and lower the user platform between a lower, compacted storage position and an elevated position using a scissors linkage that links the user platform to a drawer assembly support such as a tray. The elevating mechanism can be an actuator having a cylinder pivotably mounted to the tray and a slidable rod pivotably mounted to the scissors linkage in a manner that permits raising the seat as the rod is extended outwardly from the actuator cylinder. A  control system monitors the position of the drawer assembly and the vertical position of the user platform and can prevent undesired operation such as when a motor vehicle engine is still running or a motor vehicle door is closed.

Title: Multi-stage power supply for a load control device having a low-power mode
Inventor: SHEARER THOMAS M
IPC: H05B44/00
Filed: 2010-03-02
Abstract: A multi-stage power supply for a load control device is able to operate in a low-power mode in which the power supply has a decreased power consumption when an electrical load controlled by the load control device is off. The load control device comprises a load control circuit and a controller, which operate to control the amount of power delivered to the load. The power supply comprises a first efficient power supply (e.g., a switching power supply) operable to generate a first DC supply voltage.  The power supply further comprises a second inefficient power supply (e.g., a linear power supply) operable to receive the first DC supply voltage and to generate a second DC supply voltage for powering the controller. The controller controls the multi-stage power supply to the low-power mode when the electrical load is off, such that the magnitude of the first DC supply voltage decreases to a decreased magnitude and the inefficient power supply continues to generate the second DC supply voltage.
