Patent CA-2187141-A1 (CA)
Title: Modem with remote monitoring capability
Inventor: VALLEE RICHARD
IPC: H04M11/06
Filed: 1996-10-04
Abstract: A modem unit, typically a wireless modem unit, has a bidirectional digital data port, a modem, a transceiver, and a microcontroller programmed to control the unit according to a control program. The modem unit has a command mode, and the microcontroller is programmed to recognize certain commands by means of a prefix as remote commands and retransmit them to a remote modem unit rather than acting on them locally. The microcontroller is also programmed to monitor operating parameters of the modem unit and optionally to insert data relating to these parameters into a prefix to data strings transmitted by the modem unit and strip such prefixes from data strings received by the modem unit. The microcontroller controls switches which determine the routing of data between the port, the modem and the microcontroller so that the above functions may be implemented.

Patent CA-2189930-A1 (CA)
Title: Hole Cutter
Inventor: OMI SHOHEI
IPC: B23B51/04
Filed: 1996-11-08
Abstract: A hole cutter having a body provided with first and second types of cutting teeth.   The cutter facilitates the discharge of cutting chips during machining of a workpiece.          The tooth depth of the left and right sections of each of the second type of teeth is smaller than that of the left and right sections of each of the first type of teeth.  The tooth depth of the middle section of each tooth of the second type is greater than that of the middle section of each tooth of the first type.  A linear flattening section is provided at the middle portion of a second blade edge of each tooth of the second type.  The flattening section causes each cutting chip to be shaped in a strip-like manner when removed from the workpiece.  This separates the ends of the cutting chips from each other and prevents the chips from becoming entangled to one another.

The temperature sensitive switch is effective to open the circuit of the coil and thereby open such contacts to stop operation of the fan when ambient temperature falls to or below freezing.
Patent CA-2213486-A1 (CA)
Inventor: SCH R ALEX ROBERT
IPC: A61C5/00
Filed: 1996-03-19
Abstract: The parapulpal or endodontic anchoring elements in the form of screws or posts, respectively, obtain their fatigue-resistant geometry by use of the Computer Aided Optimization (CAO) method based on bionics. The stress concentrations which occur on conventional contours, and which lead to material fatigue and the risk of fracturing, are eliminated uniformly in this way. With the optimized thread profile (Gp) and the optimized transition profile (Up), the strength and useful life of the anchoring elements are increased many times over. The two-part cement run-off groove (112) reduces the amount of working involved when manufacturing the anchoring elements as screws.

Title: A three column cryogenic cycle for the production of impure oxygen and pure nitrogen
Inventor: FIDKOWSKI ZBIGNIEW TADEUSZ
IPC: F25J3/04
Filed: 1997-10-20
Abstract: A cryogenic process for producing impure oxygen and/or substantially pure nitrogen utilizes a classic double column arrangement and an additional third column operating at a medium pressure, i.e. between the pressure of the higher pressure stage and the lower pressure stage of the double column system. A portion of the feed air is separated in the stages of the double column system, and another portion of the feed air is distilled in the medium pressure stage. Crude liquid oxygen from the higher pressure stage and/or the medium pressure stage is reduced in pressure and boiled in a reboiler/condenser at the top of the medium pressure column. The vaporized crudeliquid oxygen from the top reboiler/condenser of the medium pressure column is subsequently introduced as a vapor feed to the lower pressure stage, which reduces irreversibilities of separation in the lower pressure stage.

Patent CA-2224850-A1 (CA)
Inventor: BIELAGUS JOSEPH B
IPC: B07B13/11
Filed: 1997-12-15
Abstract: A flow of the material is supplied to the inclined surface of a continuous looped belt. The surface of the belt is textured to form small pockets into which small particles fall and are held against downward motion as the belt is advanced up the incline. The larger particles in the material cascade down the belt and are collected for further processing. The small particles entrained in the pockets move up the incline with the belt and are removed from the belt when it reverses direction at the top of the incline. Fines removal is facilitated by an agitator which vibrates the beltas it reverses direction and moves down the incline. The size of the particles removed can be controlled by increasing the size of the pockets. The inclination can be varied to optimize the motion of the large particles down the inclined belt.

Title: Topology aggregation using parameter obtained by internodal negotiation
Inventor: IWATA ATSUSHI
IPC: H04L12/66
Filed: 1998-04-29
Abstract: In a hierarchical network, an aggregation parameter is exchanged between a node and its neighbor to agree on a negotiated parameter. A set of physical links between them are aggregated into a logical link according to the negotiated parameter and resource data of the logical link is stored in a database of each node. The resource data is then exchanged between them and the contents of the database of each node are updated with resource data of its neighbor. To optimize the link aggregation, an operating performance of the logical link is evaluated by the node using traffic data from the network, and the negotiated parameter is updated according to the detected operating performance. The updated aggregation parameter of the node is exchanged with its neighbor to agree on a negotiated updated parameter which is used to aggregate the physical links into the logical link.

Title: A method and an apparatus using ultrasound for fixedly welding a circular material blank
Inventor: ANDERSSON ANDERS
IPC: B29C57/00
Filed: 1996-12-06
Abstract: In the manufacture of packaging containers, for example blown plastic bottles, a circular material blank is, in certain cases, fixedly welded to the end of a sleeve-shaped casing portion. It is advantageous from amongst other energy viewpoint if the welding can take place using ultrasound, but in this instance it has been proved that the central region to the circular blank absorbs ultrasonic energy to such an extent that it is deformed or breaks. A method of using ultrasound to fixedly weld a circular material blank (13) without such drawbacks occurring is proposed according to the present invention in that the oscillations caused by the ultrasound are reduced by a mechanical stabilisation of the central region of the circular blank (13), which is put into effect with the aid of a vacuum and a relief pattern (18) provided in the central region of the circular blank. An apparatus for employing ultrasound to fixedly weld a circular material blank (13) in place displays a counter abutment (12) with a work surface for fixedly retaining the circular material blank, the work surface forming a part of a vacuum chamber, and support means for the central region of the circular blank during the welding cycle.
