Patent CA-2222773-A1 (CA)
Title: Distributed-protocol server
Inventor: MOLERES RICHARD P
IPC: H04L69/14
Filed: 1997-11-28
Abstract: A distributed processing system (100) includes a protocol server (101) that enables a plurality of clients (103-104) to share the use of one set of Signaling System 7 (SS7) links (99), that centralizes the link-termination circuitry (110) for use by the plurality of clients, and that provides access to upper layers (215-219) of the SS7 protocol stack (200) by distributing the processing of different layers of the stack between the protocol server and the clients. The protocol server terminates the lower layers (210-213) of the SS7 protocol, while each client terminates the upper layers of the SS7 protocol. Communication between the protocol server and the clients of information expressed in the upper layers of the SS7 protocol is effected via the TCP/IP protocol over a LAN (102). A service access bridge process (113, 116) in the protocol server translates between the lower layers of the SS7 protocol and the TCP/IP protocol, and a distributed signaling server process (114, 117) in the protocol server routes communications across the LAN. A distributed signaling client process (121, 124) in each client translates between the TCP/IP protocol and the upper layers of the SS7 protocol. The distributed signaling server and distributed signaling client processes are substantially protocol independent, allowing for use of any protocol in place of the SS7 protocol. The distributed processing system may be either a multiprocessor or a uniprocessor.

Patent CA-2231697-A1 (CA)
Title: Expandable pin plug for automated use
Inventor: HAVLINEK KENNETH
IPC: F16L55/11
Filed: 1998-03-09
Abstract: This invention is a new device that can be used to plug perforations in materials. This plug comprises a cylinder plug with a tapered bore partially extending through the plug from one end. A cylinder pin that is tapered substantially the same as the plug will fit in the plug after installation is complete. A shear flange surrounds the pin so that when the pin is installed in the plug, the shear flange is against a plug flange. The pin is adhered to the plug by means such as a thin layer of epoxy or glue which allows the pin and plug to be handled as a single component. The pin is designed so that while in this position, there is no significant radial expansion of the plug. The pin has a pattern of holes or grooves that extend the entire length of the pin in order toallow for the expansion of any trapped fluids in the bore of the plug. The pin can have a groove along the outer diameter to allow for easier handling of the pin. The diameter size of these openings are not important, as long as the openings are large enough to resist plugging with debris.

Patent CA-2234063-A1 (CA)
Title: Corner piece for siding retainers
Inventor: MAROUSEK ROBERT Y
IPC: E04F13/08
Filed: 1998-04-06
Abstract: A corner piece used in cooperation with retainer strips and exterior siding provides improved protection to a wall of a structure, particularly around rectangular openings in the wall. The corner piece includes a first section extending in a first direction along a first side of the opening and a second section integral with the first section. The second section extends in a direction substantially perpendicular to the first section along a second side of the opening adjacent the first side. The first and second sections form a continuous channel that extends into the retainer strips. A first retainer strip may be received within the first section and the second section of the corner piece may be received within a second retainer strip. As a result, the channel formed by the first retainer strip overlaps a portion of the first section and the channel formed by the second section of the corner piece overlaps a portion of the second retainer strip. Thus, water flowing in the channel formed by the retainer strips and corner piece may flow from a retainer strip, over the corner piece and past another retainer strip with minimal opportunity for the water to flow behind either the corner piece or either of the retainer strips. In addition, the continuous channel formed by the corner piece and retainer strips directs water away from the wall by an angled bottom surface of the channel.

Patent CA-2238701-A1 (CA)
Inventor: GUINN RONALD K
IPC: A01D41/14
Filed: 1998-05-27
Abstract: The hydraulic flotation circuit for the header of a windrower or other harvester utilizes a pair of precharged gas accumulators that are always in opencommunication with the flotation cylinders of the circuit. One of the accumulators is set at a relatively high precharge pressure, while the other is set at a much lower precharge pressure. If the header chosen for attachment to the harvester is relatively heavy, the accumulator with the higher precharge pressure provides the flotation bias, while if the header is relatively light, the accumulator having the lower precharge pressure comes into play.
Patent CA-2239395-A1 (CA)
Title: A chirp-controlled optical modulator and method of controlling chirp in the modulation of an optical signal
Inventor: JACKSON MICHAEL
IPC: G02F1/313
Filed: 1998-06-02
Abstract: An optical signal is modulated by passing it through an optical signal path in an optical modulator. Different electric fields are applied across a first pair of parallel phase modulation arms so as to produce different signal phase modulations in respective portions of the optical signal and different electric fields are also applied across a second pair of parallel phase modulation arms so as to produce different signal phase modulations in respective portions of the optical signal. The different magnitudes of the electric fields are pre-determined so as to control chirp and to promote modulation linearity. The chirp in the optical signal output from the optical modulator may be reduced or even eliminated or may be predetermined to counteract or even eliminate chirp generated in a transmission path.

Title: Multiple capillary biochemical analyzer with barrier member
Inventor: DOVICHI NORMAN J
IPC: G01N21/64
Filed: 1996-12-19
Abstract: A multiple capillary biochemical analyzer for sequencing DNA and performing other analyses, in which a set of capillaries extends from wells (30) in a microtiter plate (32) into a cuvette (22). In the cuvette (22) the capillaries are held on fixed closely spaced centers by passing through a sandwich construction having a pair of metal shims (64, 66) which squeeze between them a rubber gasket (84) forming a leak        (See formula I) proof seal for an interior chamber in which the capillary ends are positioned. Sheath fluid enters the chamber and entrains filament sample streams from the capillaries. The filament sample streams, and sheath fluid, flow through aligned holes in a barrier member (90) spaced close to the capillary ends, into a collection chamber (102) having a lower glass window (100). The filament streams are illuminated above the barrier member by a laser (130) causing them to fluoresce. The fluorescence is viewed end-on by a CCD camera chip ( 138) located below the glass window ( 100). The arrangement ensures an equal optical path length from all fluorescing spots to the CCD chip and also blocks scattered fluorescence illumination, providing more uniform results and an improved signal to noise ratio.
