Title: Intravenous injection site having wipeable septum and valve structure
Inventor: ENNS THOMAS F
IPC: A61M39/26
Filed: 1997-07-11
Granted: 2000-02-22
Abstract: A medical intravenous injection site is provided having a single piece elastomeric septum and valve combination element. The septum has a slit therein,through which a blunt cannula or a male luer slip or male luer taper can be inserted. A valve element is suspended below the septum by straps extending between the septum and valve element, and formed integrally with them as a single, one-pieceelastomeric septum, valve, and strap structure. When the blunt cannula is inserted through the slit in the septum, the valve portion will be displaced away from the septum portion, and away from a valve seat formed in the interior of a substantially rigid housing in which the septum and valve structure is mounted. Fluid communication, in either direction past the valve seat, may therefore be established. Because the septum is mounted across the end of the rigid housing, it is wipeable. Thus, a needleless injection site is provided, thereby permitting injection of fluids to or withdrawal of fluids from a patient, through the injection site.

Patent CA-2216980-C (CA)
Inventor: OHNO RYUICHI
IPC: H04L29/06
Filed: 1997-09-30
Granted: 2001-09-25
Abstract: A method of increasing the network use efficiency of computer communication and reducing the limitation of byte stream in a transmit/receive request.          A virtual circuit is established between protocol modules such as applications for providing the communication function between softwares to mate one transmit request with one receive request.  By returning an acknowledgement in a unit of request, any vain acknowledgement can be avoided and even in the case of asynchronous transmission/reception, a request which is completed in transmission/reception can be ended immediately, thus permitting efficient data transfer.          Even when the transmit request length and the receive request length differ from each other, reliable communication of a request having a smaller request length can be ensured between mating transmit and receive requests.        Further, in the case of synchronous transmission/reception, by copying only the latter half of a transmission buffer and returning a virtual ACK to the transmitting side when reception of the former half ends, the acknowledgement need not be waited for, thus permitting efficient data transfer.

Patent CA-2219674-C (CA)
Inventor: OLDIGES DONALD A
IPC: C10M177/00
Filed: 1996-04-30
Granted: 2001-07-10
Abstract: The present invention discloses the use of nonmetallic, finely divided polymeric or natural fibers in anti-seize thread compound formulations for use on rotary shouldered, oilfield tubular good or tapered threaded connections.  The addition of such fibers into formulas that do not contain metallic powders or flakes (typically utilized to provide the anti-galling properties) provides a measurable improvement in the galling and seize resistance properties.  Therefore, the incorporation of such fibers provides a film strength improvement in environmentally responsible thread compound compositions, which previously would not provide the level of galling resistance to perform in severe applications such as oilfield directional or geothermal drilling.
Patent CA-2220393-C (CA)
Inventor: GIALLORENZI THOMAS ROBERT
IPC: H04J13/00
Filed: 1996-05-08
Granted: 2007-03-27
Abstract: An electronic data transmission system has a low peak-to-average power ratio by including a transmitter circuit which receives an input signal and in response generates a distorted output signal. This distorted output signal is generated by amplifying the input signal with one particular gain when the input signal is at a maximum magnitude which gives the distorted output signal a corresponding maximum magnitude, and by amplifying the input signal with a larger gain when the input signal is in a predetermined range below the maximum magnitude. The distorted output signal travels over a communication channel to a receiver circuit, which regenerates the input signal by amplifying the distorted output signal with a gain that is the inverse of the gain by which the distorted signal is generated.
