Title: Rapid triglyceride assay for use in pulp pitch control
Inventor: YEZZI ROBIN M
IPC: D21C9/00
Filed: 2002-04-19
Abstract: Enzymatic methods are provided for determining the surface triglycerides content in a sample of wood pulp. The methods preferably comprise reacting triglycerides which are present on the surface of the wood pulp fibers in the sample in the presence of a lipase to form glycerol and fatty acids, and then determining the difference between the amount of free glycerol present in the sample and the amount of glycerol formed from said triglycerides. The method is useful as a quick, portable, accurate, and low cost assay for assessing the amount of triglycerides present at various sample points in pulp and paper mills, which advantageously serves as a diagnostic tool for use in controlling the undesirable deposition of pitch during the papermaking process.

Title: Method to synchronize and upload an offloaded network stack connection with a network stack
Inventor: PINKERTON JAMES
IPC: G06F9/46
Filed: 2003-04-14
Abstract: A method to synchronize and upload an offloaded network stack connection between a host network stack and peripheral device is presented. A state object for each layer in the stack is sent to the device that includes state variables that are classified as a constant, a cached variable handled by the host, or a delegated variable handled by the device. State that must be updated by the network stack and the peripheral device is cleanly divided. For example, statistics are tracked by the host, the device, or the host and the device. A statistic tracked by both the host and peripheral device is divided into non-overlapping portions and combined to produce the statistic. Once an upload is initiated, the device achieves a consistent state and hands delegated states to the stack. Each layer in the stack takes control of its delegated state and resources at the device are freed.

The magnetic attachement facilitates attachment and removal without the need to provide holes in the body, and upon heating and expansion of the baffle (12), the baffle material (24) expands to fill cavities and adhere to the inside wall surface of the body on which it is received.
Patent CA-2427677-A1 (CA)
Title: Dual valve fitting for enabling quick measurement of pressure
Inventor: SCOTT DANIEL G
IPC: B60T17/04
Filed: 1998-03-26
Abstract: A dual valve fitting enables quick measurement of pressure contained within a housing and a dual valve fitting that includes first and second valve bodies.  The first valve body defines a flow passage from a threaded end to a protuberant end which is shaped to mate with a female coupler of a quick connect device. A first valve in the flow passage features a poppet type head at a top end of a valve stem that is seatable against an outer annular valve seat formed in the flow passage. A first biasing mechanism compels the poppet type head against the outer annular valve seat so that the first valve is normally closed. The second valve body defines a flow bore from an upper threaded end to a lower threaded end which communicates with the flow passage of the first valve body. The upper threaded end connects with the treaded end of the first valve body whereas the lower threaded end is designed to screw into a threaded bore of a housing. Situated in the flow bore, a second valve features a retainer that defines in a top end a recess that retains a check type valve that is seatable against an inner annular valve seat formed in the flow bore. A second mechanism for biasing acts upon the retainer so that the check type valve therein seats against the inner annular valve seat thereby rendering the second valve normally closed. A stem extension is disposed between a bottom end of the valve stem and a top side of the check type valve. When mated to the protuberant end of the fitting, such female coupler causes translation of the valve stem, the stem extension and the retainer thereby opening both the first and second valves. This allows flow from such housing through the flow bore and the flow passage and into such female coupler.

Title: Auto-compression for media over ip
Inventor: PRESNELL MICHAEL CRAIG
IPC: H04L12/56
Filed: 2004-03-25
Abstract: The present invention allows communicating devices to control the amount of compression used in packet sessions for transmitting streaming media to and from each other. When a communicating device detects a decrease in performance or quality of service indicative of a limited bandwidth condition, the amount of compression for the current or subsequent sessions is temporarily increased to allow the currently available bandwidth to support the session or subsequent sessions. After a set period of time, or when the limited bandwidth condition is removed, communications associated with the sessions can revert back to transporting uncompressed data or reducing the amount of compression for the sessions, thus using more of the available bandwidth.
