Title: Chemical treatments for fibers and wire-coated composite strands for molding fiber-reinforced thermoplastic composite articles
Inventor: WOODSIDE ANDREW B
IPC: C03C25/26
Filed: 1997-08-07
Granted: 2005-10-25
Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers (10), such as reinforcing fibers (12) suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable. Heat energy may be employed to lower the viscosity and improve the wetting ability of th e applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers (32) are used to form a composite strand (14), which may be subsequently processed in-line or off-line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet for m and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles. Each strand is made from fibers, including reinforcing fibers and optionally fibers of a matrix material, that are impregnated with a chemical treatment so that the treatment is disposed between substantially all of the fibers.

Title: Circuit for monitoring optical signals
Inventor: COLBOURNE PAUL
IPC: H04B10/08
Filed: 1999-04-29
Granted: 2002-11-19
Abstract: The present invention relates to a circuit for monitoring optical signals in a multiple channel system. A tunable band pass filter receives and input signal comprising multiple channels each having a different wavelength and predetermined channel spacing.  Output from the tunable filter is directed to a second filter having a periodic response with wavelength, such as an etalon. The response is designed to block wavelengths of light corresponding to the channels, permitting noise in the inter-channel space to be measured by a detector. A reference circuit launches light from a broad band source through a Bragg grating into the tunable filter. The Bragg grating reflects a known reference wavelength. Light which passes from the reference source through the tunable filter is also passed through the second filter to a detector. When a notch is detected by the reference detector, the tunable filter is known to be tuned to the reference wavelength. A comparison to the signal output at the first detector is used to correlate the position of the notch and the location of any inter-channel noise. A third filter, also preferably a fixed etalon, has a periodic response which matches the channel spacing designed to block wavelengths of light corresponding to the inter-channel spaces. A third detector measures the channel amplitude and also correlates the response with the reference notch to identify the individual channels. Advantageously, the monitoring circuit can provide channel and noise information associated with each channel without using costly and complex elements to identify the wavelength of the responses.

Abstract: A steering arm assembly for use with railway car trucks having pivotal frames and brake systems is disclosed. The steering arm assembly has two U-shaped sub-assemblies. Each sub-assembly has two side arms connected by a center arm. The side arms each have vertical open paths between top and bottom holes in their surfaces and open side paths through side access holes in their sidewalls. The open side paths intersect the vertical open paths. The vertical open paths are positioned to be aligned over the brake system brake shoe keys and the side access holes are positioned to be aligned with the side windows in the side frame. When it is desired to remove or replace a brake shoe, the brake shoe key may be moved upwardly through the vertical open path. This movement may be facilitated through use of a tool inserted through the side access hole and open side path in the side arm. A  method of changing brake shoe keys and the combination of such a steering arm assembly in a railway car truck is also disclosed.

Abstract: Procedure for resolving the specifications has a number of steps starting with formulation of the audit conditions that one wishes to detect using the specification formulae. The audit conditions are used to express forms of attack that can be detected by examination of the system log file. The specification formulae are then expanded using an algorithm into sub-formulae, a scanning stage by a software interpreter is used with the sub-formulae to generate Horn Clauses, positive Horn clauses from a stack of completed sub-formulae are then memorized in a table and a resolution stage starting with the positive clauses is used to produce an output file or a system action. The above stages are repeated for all the entries in the system log.

Title: A method and apparatus for controlling the flow of variable-length packets through a multiport switch
Inventor: BAUMAN JAMES A
IPC: H04L12/56
Filed: 1999-04-29
Granted: 2003-04-01
Abstract: A method and apparatus for controlling the flow of variable-length packets to a multiport switch involve accessing forwarding information in a memory (214) based at least partially on layer 4 information from a packet and then forwarding (186) the packet only if the packet is within a bandwidth consumption limit that is specified in the forwarding information. In a preferred embodiment, a credit bucket algorithm is used to ensure that packet flows are within specified bandwidth consumption limits. The preferred method for implementing the credit bucket algorithm to control flows of packets involves first receiving a particular packet from a flow and then stripping the layer 2 header information from the packet. The layer 3 and layer 4 information from the packet is then used to look-up (170) flow-specific forwarding and flow control information in a memory that stores a linked list of table entries that includes the fields necessary to implement the credit bucket algorithm. The credit bucket algorithm is implemented in embedded devices within an application-specific integrated circuit, allowing the control of packet flows based on the application of the flow.
