Title: Switchable wavelength router
Inventor: WU KUANG-YI
IPC: H04B10/29
Filed: 1998-01-05
Abstract: A switchable wavelength router (999) having an input port (11) for the incoming WDM signal (500) and two output ports (13, 14) for de-multiplexing the WDM signals (500). The router (999) divides the received optical signals into divided optical signals (101, 102) comprising a subset of the channels and spatially positions the divided optical signals in response to a control signal applied to the router (999). For example, the router (999) can divide a received WDM signal (500) into two subsets that are either single channel or WDM signals. Multiple routers (999) can be cascaded to form a 2n switchable wavelength router, where n is the number of stages of wavelength routers.

Patent CA-2298893-A1 (CA)
Inventor: CHAHLEY DENNIS W
IPC: B05B1/30
Filed: 2000-02-15
Abstract: The present invention relates to a flow control system for sprayer nozzles. The control system includes a solenoid coil and a solenoid plunger. The solenoid plunger can slide into an adapter body, substantially perpendicular to the direction of fluid flow. In reducing the fluid flow through the nozzle, the plunger is moved to block an orifice in the path of the fluid flow, within the adapter. The plunger movement is achieved through the energization of the solenoid coil, with signals sent by a controller. The orifice in the adapter is manufactured to a specific size which allows reduced power consumption to shut off or reduce flow through the nozzle. Also, the orifice is sized to provide unrestricted flow when fully open. By means of the controller, control can be provided individually to each nozzle from a plurality of nozzles on a spraying bar. In one aspect of the invention, the flow control system can be used on agricultural sprayers with sensing equipment such as cameras that may determine the green condition of the foliage being sprayed. According to the determined condition, the controller would regulate the flow through the nozzles in the corresponding area of the field. The control valve adapts to industry standard fittings and adapts to a position on the fittings so the spray fluid passes through the filter and nozzle check valve before passing through the control valve while the nozzle check valve remains in place. Specifically, the control valve can be adapted onto a standard fitting and inserted between the nozzle screen and spray tip.

Title: Injector/valve combination designed to improve color dosing response time
Inventor: PITMAN FRANK MARK
IPC: B29B7/60
Filed: 2000-02-22
Abstract: This invention relates to an improved injector/valve combination which permits nearly immediate response time to an actuator signal. Such a combination is particularly suited for injecting colorants into polyurethane slabstock foam and permits a substantial reduction in foam waste due to low colorations during an on/off cycle. Specifically, this invention combination comprises a novel ball valve which allows for instantaneous shut-off and -on without appreciable leakage or pressure drop and without the need to utilize a high throughput flow rate. Such a ball valve is used in combination with an injector which is actually attached to the valve, the configuration which permits continuous use and instantaneous on/off without a deleterious pressure drop and minimizes the possibility of turbulence as the liquid polymeric colorant flows through the injector. The ball valve, the attached injector configuration, the coloring apparatus comprising the inventive ball valve and/or the attached injector configuration, and the slabstock foam colored through the utilization of such an apparatus are also contemplated within this invention.
