Patent CA-2255022-A1 (CA)
Inventor: MATTE SYLVAIN
IPC: F01L9/16
Filed: 1998-12-04
Abstract: A valve assembly located adjacent the cylinder structure of a two-stroke engine including a valve piston, a diaphragm and a restricting member. The valve assembly is adapted to vary the height of the exhaust port of this type of engine by moving a restricting member, located in a guide channel communicating with the exhaust port, from a full-flow height position to a restrictive height position (and vice versa) . The force necessary to actuate the restricting member is a pressurized medium or a vacuum. A solenoid valve controls the pressurized medium or vacuum delivery to the valve assembly according to the engine speed N and throttle opening for optimum efficiency.
Patent CA-2257331-A1 (CA)
Inventor: DURWARD JAMES
IPC: G06K9/00
Filed: 1998-12-31
Abstract: The invention is a process for accelerating the disclosure of the presence of hydrocarbon by using pattern recognition to search a scanned-image well log database. In the past, many oil&gas wells were never brought into production because at the time they were drilled, the amount of hydrocarbon found was not economical due to either low commodity prices or a lack of an economic way of getting the hydrocarbon to market. Because of these and other factors, large amounts of hydrocarbon that was discovered in the past was not produced and the wells were plugged and left as "dry and abandoned". Today, due to higher commodity prices and plentiful delivery mechanisms, there is tremendous effort expended by exploration and production companies to both locate and re-enter these types of wells in order to produce the by-passed hydrocarbon, and to drill new wells in proximity. In a large number of cases the mineral rights to these wells are readily available.

Title: Real-time digital audio compression/decompression system
Inventor: JONES RONALD JAMES JR
IPC: H03M7/30
Filed: 1994-12-23
Abstract: Digitized audio information is compressed by retrieving a first audio sample from a digitized audio signal and storing it in its entire, uncompressed, form. The next audio sample is then retrieved and a signed difference between the first audio sample value and the next audio sample value is computed. If this difference value can be represented in fewer data segments than would be required to represent the next audio sample, the difference value is stored, rather than the value of the next sample, otherwise the next sample is stored. The invention proceeds in this fashion until the entire PCM audio signal is compressed and stored. The compressed data stream is decompressed to generate an output data stream by retrieving a stored sample and examining it to ascertain whether it is a difference value or a flag which indicates that the following data represents a coded amplitude value. If the sample is a difference value it is digitally added to the previous value (taking into account the sign) and the sum is inserted into the output data stream. The sum value is retained in order to be used to compute the next output value if the following sample is also a difference value. Alternatively, if the sample is a flag value it is discarded and the next sample is retrieved and inserted into the output data stream.

Title: An extendible member
Inventor: DATON-LOVETT ANDREW J
IPC: B32B5/26
Filed: 1997-03-25
Abstract: An extendible sheet member is configurable between first and second states.  The first state is a coiled state (1.1) in which the member is coiled substantially parallel to a first axis and the second state is an extended state (1.2) in which the member extends substantially parallel to a second axis at some angle to the first axis. The member is made wholly or in part from a material or materials which give rise to internal stresses upon extension, these stresses acting at some angle to the second axis such as to bias the member to the second state. In many embodiments these stresses are produced by fibres which form part of the structure of said member. Said member is preferably reversibly configurable between said first and second states.

Title: Multilayer firewall system
Inventor: NESSETT DANNY M
IPC: G06F13/00
Filed: 1998-05-28
Abstract: A system provides for establishing security in a network (10) that includes nodes having security functions operating in multiple protocol layers. Multiple network devices, such as remote access equipment (13), routers (14), switches (12), repeaters (16) and network cards (15) having security functions are configured to contribute to implementation of distributed firewall functions in the network. By distributing firewall functionality throughout many layers of the network in a variety of network devices, a pervasive firewall is implemented. The pervasive, multilayer firewall includes a policy definition component (11) that accepts policy data that define how the firewall should behave. The multilayer firewall also includes a collection of network devices that are used to enforce the defined policy. The security functions operating in this collection of network devices across multiple protocol layers are coordinated by the policy definition component so that particular devices enforce that part of the policy pertinent to their part of the network.

Title: Refractometre interferometrique a plage etendue
Inventor: SHEPARD DOUGLAS W
IPC: G01N21/45
Filed: 1998-06-08
Abstract: La présente invention concerne un détecteur à indice de réfraction interférométrique, dont la plage de fonctionnement est presque illimitée comparativement à un réfractomètre interférométrique classique dit de polarisation, dont la plage dynamique est limitée à une plage relativement étroite d'indices de réfraction. La mesure de la différence d'indice de réfraction entre un échantillon et une cellule de référence est effectuée par mesure de l'angle selon lequel le plan de polarisation d'un faisceau combiné a pivoté. Dans le dispositif classique, l'angle est limité à environ .pi. radians, ce qui correspond à un décalage d'une demi-longueur d'ondes entre les composants de référence et d'échantillon dudit faisceau associé. Le dispositif à plage étendue permet de suivre et de mesurer, de manière précise, cet angle sur plusieurs rotations. Le suivi de la rotation est effectué par l'un des trois modes de réalisation, le mode de réalisation préféré impliquant l'utilisation d'un retardateur à cristaux liquides. Selon les trois modes de réalisation, il est possible de mesurer le sinus et le cosinus de l'angle de rotation et, de ce fait, il est possible de calculer une tangente inverse à quatre quadrants de façon à réaliser directement l'angle de rotation.
