Abstract: A method and a system in which selected wavelengths of a wavelength division multiplexed (WDM) signal are modulated with multicast data for multicasting data services on an optical network. The WDM signal is received from a hub node of the optical network, such as a unidirectional ring network or a bi-directional ring network. A four-port wavelength crossbar switch (4WCS) selectably switches selected wavelengths from the optical network to a modulator loop. The modulator loop includes a multicast modulator that modulates the selected plurality of wavelengths with the multicast data. Each modulated wavelength is then switched back to the optical network by the 4WCS switch, and sent to a plurality of subscriber nodes of the optical network. This architecture allows a facility provider to be physically separated from a content provider, and affords the flexibility of selectively delivering multicast content to individual subscribers.

Abstract: The present invention relates to a synchronization method and apparatus, wherein a first end point entering a connection mode change state transmits a request message to a second end point. The second endpoint enters the connection mode change state in response to the receipt of the request message and transmits an acknowledgment and a numbered frame to the first end point. Having received the acknowledgment, the first endpoint leaves the connection mode change state and transmits an aknowledgment acknowledging the numbered frame to the second end point which leaves the connection mode change state in response to the receipt of the acknowledgment. Thus, the receipt of the acknowledgment acknowledging the numbered frame is received by the second end point irrespective of a DTX condition at the first end point, since a number ed frame is always acknowledged.

Abstract: A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. To the collated fibers is applied a resin so as to permeate through the layers and the materials are passed through a die to set the resin. The first and second layers are arranged to form first and second opposed surfaces of the part with the intermediate layer therebetween.  The resin is a two part urethane resin which has sufficient strength to prevent the fibers from the first and second layers at the first and second surfaces respectively from breaking through the surface on bending of the wall thus allowing the use of the rovings at the surfaces with the transverse fibers therebetween so that the transverse fibers can be formed from loose or chopped fiber material from rovings rather than more expensive mat.

Inventor: CRESSWELL MARK
IPC: G01F1/05
Filed: 2002-08-14
Granted: 2006-07-25
Abstract: A system for maintaining an appropriate air flow in an air stream in an air seeder. A fan provides an air stream to carry agricultural materials for distribution across a width of a seeding implement. A tank contains a granular agricultural material and a metering device dispenses the material into the air stream. The system is calibrated such that a known weight of material is dispensed for each revolution of the metering device whereby the rotational speed of the metering device multiplied by the known weight per revolution results in a known per minute rate of agricultural material being dispensed into the air stream. A microprocessor is programmed to derive an appropriate fan speed for the per minute rate of agricultural material being dispensed and send a signal to a fan control to adjust the speed of the fan to correspond to the appropriate fan speed.

Title: Anti-drool sprue gated cross over nozzle
Inventor: BERCEANU MIHAI
IPC: B29C45/72
Filed: 2003-01-17
Granted: 2010-07-06
Abstract: According to the present invention a coding plate is interspersed between first and second respective inlet and outlet cross over nozzle parts. The cooling plate engages ends of the cross over nozzles during mould filling and provides a melt transfer passage therebetween. Once the mould is filled, the cooling plate acts to dissipate heat from the melt transfer passage thereby promoting solidification of melt therein. Accordingly melt solidification in the sprue is assured with more certainty than prior art designs enabling relatively fax mould cycling with minimal risk of drool.

Abstract: A device is provided for winding paper in which the paper web running is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. The device applies a heated adhesive agent on the web and/or on the reel shaft onto which the web is to be wound. A spray rack is mounted on the stand of the reel-up, upstream of the reel drum and extending transversely to the machine direction, or alternatively, is mounted in various other locations of the reel-up. A hopper with a heater heats the heated adhesive agent to temporarily lower its viscosity and stickness for smooth and even spraying. The series of nozzles are mounted on the rack spaced across the width of the web to spread spray jets of liquid containing said heated adhesive onto the web and/or the reel shaft. The adhesive area thus is disposed between the web and the empty reel shaft so as to facilitate initiating the winding process.

Abstract: A system and a method to control the motion of envelopes within a postage printing module to accommodate the use of slower print techniques and to achieve high throughput in a mail processing system. The system transports envelopes according to a motion profile in which the envelope is decelerated from a transport velocity to a slower printing velocity. After the printing operation has been completed, the envelope is accelerated back to the transport velocity and transferred to a downstream module. None of the intervals of deceleration, low print velocity, or acceleration may occur while an envelope in the postage printing module is also in the control of another module. The print head is geared to operate in synchronism with the print transport.
