Title: Electronic multi-purpose material level sensor
Inventor: MCEWAN THOMAS E
IPC: G01S17/10
Filed: 1995-12-05
Abstract: A sensor for determining the surface or interface level of a material comprising a transceiver (12) and an inner conductor (21) of a coaxial cable (16) electrically coupling the transceiver (12) to a guide wire (14) partially immersed in the material. A launcher plate (18) is connected to the outer shield (19) of the cable (16) and an impedance (20) connects the launcher plate (18) to the guide wire (14). The launcher plate (18) produces a fiducial pulse back to the transceiver (12).  Electromagnetic waves transmitted from the launcher plate (18) propagate along the guide wire (14). The waves are reflected by the surface or interface, received by the laucher plate (18) and transmitted as reflected pulses to the transceiver (12). The transceiver (12) determines a time delay between the fiducial and reflected pulses to establish the surface or interface level relative to the launcher plate (18).

Patent CA-2224023-A1 (CA)
Title: Virtual wide area centrex
Inventor: TURNER GEORGE W
IPC: H04Q3/47
Filed: 1997-12-05
Abstract: A method is disclosed which brings together a combination  of  special  IN  features  and  techniques  to allow  Centrex  stations  supported  by  a  plurality  of central  office  switching  systems,  each  at  different locations, to function from the customer's perspective as though  they  were  served  by  a  single  central  office switch.  The key to Virtual Wide Area Centrex is a total separation of  the  telephone  numbers  seen  and used by customers   (Customer  Number  Address - CNA)   from  the telephone numbers used internally by the network for call routing purposes  (Network Node Address - NNA), such that there  are  two  separate  and  distinct  numbering  plan domains.  A central database, interconnected with each of the Centrex switches, maintains the mapping between CNA and NNA.   This database is called upon, as required, to do both forward and reverse translations - i.e., from CNA to  NNA  and vice-versa.  The  net  result  is  that  CNA identify people  (e.g.,  a customer's  specific employees and agents) whereas NNA identify locations (e.g., offices and conference rooms).   This permits an environment in which individuals may move from one physical location to another, regardless of the serving central office switch, while  keeping  their  CNA  and  their  network  access privileges.

Patent CA-2228426-A1 (CA)
Inventor: CANHAM LEIGH TREVOR
IPC: A61L27/32
Filed: 1996-08-01
Abstract: Biomaterial, for example bioactive silicon, may be fabricated by anodising a silicon wafer to produce a wafer (10) having a porous silicon region (20). In vitro experiments have shown that certain types of porous silicon cause the deposition of apatite deposits both on the porous silicon (20) and neighbouring areas of bulk silicon (22) when immersed in a simulated body fluid solution. This deposition of apatite provides an indication that porous silicon of appropriate form is bioactive, and therefore also biocompatible. A form of porous silicon is dissolved in the simulated body fluid solution and this is an indication of a resorbable biomaterial characteristic. In addition to porous silicon, certain types of polycrystalline silicon exhibit bioactive characteristics. Bioactive silicon may be used in the fabrication of biosensors for in vitro or in vivo applications. The bioactivity of the bioactive silicon may be controlled by the application of an electrical potential thereto.

Title: Fuel tank filler assembly for engine driven welder
Inventor: TRINKNER MICHAEL J
IPC: B23K9/32
Filed: 1998-04-15
Abstract: An engine driven welder has a fuel tank with a filler tube that extends upwardly from a reservoir in the machine base.      The filler tube upper end and a cap thereon are below the machine top cover. The machine top cover has a cutout into which is installed a grommet that closes the cutout and that fully protects the filler tube upper end and the cap. The grommet has a hole that seals over a top portion of the filler tube such that any spilled fuel does not leak inside the machine. The filler tube has an expansion space that prevents splashback and spillover during fueling. An angled tail pipe directs engine exhaust away from the welding machine in any desired direction.

Patent CA-2237286-A1 (CA)
Inventor: TEWANI KAMLESH T
IPC: H04Q11/04
Filed: 1998-05-11
Abstract: A method is provided which reduces post-dial delay in a number portability environment.  In particular, a switching office which controls call routing to portable numbers (NPA-NXXs) contains a cache for which location routing number response information may be stored.  The processing office concurrently checks the cache for LRN response information corresponding to the dialed number and launches a query to a number portability database. Thus, if the LRN response information in the cache is valid then the call will be routed in the timeliest manner.  However, if either the cache does not have any LRN response information or the LRN response information in the cache proves not to be valid then, the switching office will have received the LRN response information from the database more quickly based on the concurrent launching of a query.  Therefore, a more timely attempt at establishing a proper connection to the dialed number will occur thereby reducing post-dial delay, regardless of whether or not the dialed number is ported.

Title: Slave cylinder stabilizer for harvester header
Inventor: SCHROEDER JAMES W
IPC: A01D41/14
Filed: 1998-05-27
Abstract: The windrower or other harvester has a hydraulic lift circuit for its header that includes a pair of double-acting cylinders which operate in concert to raise the header and provide a solid, lower limit for downward swinging of the header. The two cylinders are connected to one another in a master-slave relationship, and the slave cylinder has its return line normally blocked by a one-way check valve so that a body of fluid is trapped against the piston of the slave cylinder during field operations. This stabilizes the two cylinders to reduce header bounce.
