Patent CA-2440815-C (CA)
Inventor: PETERS VOLKER
IPC: E21B47/18
Filed: 2002-03-13
Granted: 2007-11-06
Abstract: A reciprocating pulser system for generating pressure fluctuations in a flowing drilling fluid comprising a reciprocating poppet and a stationary valve assembly with axial flow passages. The poppet reciprocates in close proximity to the valve assembly, at least partially blocking the flow through the valve assembly and generating oscillating pressure pulses. The poppet passes through two zero speed positions during each cycle, enabling rapid changes in signal phase, frequency, and/or amplitude thereby facilitating enhanced data encoding. The poppet is driven by a linear electric motor disposed in a lubricant filled housing. In one embodiment, the housing to shaft seal is a flexible bellows. In one embodiment, a force balance spring is used to essentially offset the hydraulic flow forces on the poppet. In one embodiment, a bypass poppet is used to adjust the differential pressure across the valve assembly.

Title: Alternate routing of voice communication in a packet-based network
Inventor: MUSSMAN HARRY EDWARD
IPC: H04L12/00
Filed: 2002-04-08
Granted: 2012-06-05
Abstract: A method for performing alternate and therefore least cost routing in distributed H.323 Voice over IP (VoIP) networks is provided. With this method, the VoIP network consists of a hierarchy of gatekeeper (GK) functions to provide alternate routing, network element redundancy, and scalability. The alternate routing function is performed by a directory gatekeeper with route selection advancing from a first route to a second route by either of two conditions: (1) there are no resources available to terminate the call in the first zone; and (2) a lack of response to the directory GK request for such resources.

Abstract: Dual shell microcapsule aggregate particles and copy materials coated therewith, such aggregate particles having inner shells surrounding chromogenic nucleus material, and outer shells encompassing multiple such inner shells to form aggregate particles thereof. The inner shells are derived from polar pre-polymer compositions. The outer shells are derived from complex colloids such as gelatin and gelatin derivatives. The outer shell material causes agglomeration of the inner shells into aggregate particles, thus increasing the sizes of the particles without increasing the sizes of the respective inner-shell microcapsules which contain the chromogenic material.

Abstract: A injector comprises a cylindrical barrel to which a needle is to be attached, and a plunger having a gasket on the tip thereof which slides within the cylindrical barrel. The gasket is in a substantially discoid form and has an annular groove to provide a bending portion which can bend either towards or away from the plunger. When a medical fluid is introduced into the barrel by retracting the plunger, the negative pressure inside the barrel results in the bending portion bending away from the plunger causing the gasket to tightly contact the inner wall surface of the barrel. When the medical fluid is discharged by pushing the plunger in the opposite direction, the positive pressure bends the bending portion towards the plunger so that the gasket again tightly contacts the inner wall surface of the barrel.

Abstract: A product and method for the removal of pollutant heavy metals from aqueous solutions which precludes the end user from storing, handling, feeding and controlling hazardous soluble sulfide materials. The product is a slurry which includes a mixture of a liquid medium and an essentially insoluble salt wherein the salt is the reaction product of heavy metal ions, preferably selected from Mn++ ions, Fe++ ions, and Fe+++ ions, and sulfide ions derived from soluble sulfide sources such as sodium sulfide, hydrogen sulfide, and sodium hydrosulfide. Addition of the subject slurry to a wastewater stream will effect the precipitation of heavy metals with lesser equilibrium sulfide ion concentration than that of the essentially insoluble salt. Solids collected by this method may be returned to subsequent wastewater streams for additional removal of heavy metals by any excess heavy metal sulfide salt.

Abstract: A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer is essentially free of fibreglass and comprises a polymeric substrate having disposed therein a plurality of porous material layers. It has been found that the use of fibreglass as a reinforcing material (and other sheet materials having a tensile modulus of greater than or equal to about 0.5 GPa when measured pursuant to ASTM D 5034) in a foam laminate product can be avoided by using a porous material layer in place of the fibreglass. In a preferred embodiment of the invention, the porous material layer has a tensile modulus less than that of fibreglass mat yet can be used to produce a foam laminate product having significantly higher strength properties.

Abstract: A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range "serial" type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.
