Patent CA-2308495-C (CA)
Title: Anaesthetic formulation
Inventor: BROWN STEPHEN
IPC: A61P23/02
Filed: 1998-11-19
Granted: 2009-01-06
Abstract: A pharmaceutically acceptable aqueous solution which is isobaric or hyperbaric, and isotonic, with respect to cerebrospinal fluid (CSF), comprises a 1-alkyl-N-(2,6-dimethylphenyl)-2-piperidinecarboxamide anaesthetic agent such as bupivacaine or levobupivacaine and a saccharide. If the amount of the anaesthetic agent is no more than 0.75 % w/v, a salt or another additional non-saccharide is present. Accordingly, the amount of the saccharide can be kept below that which would provide isotonicity in the absence of the additional non-saccharide.

Abstract: A rotatable saw unit for optimized log breakdown includes a saw unit immediately downstream of an infeed conveyor and cooperating with the infeed conveyor for sawing a workpiece as the workpiece is translated by the infeed conveyor into the saw unit. The saw unit includes at least one saw aligned for sawing of the workpiece parallel to a longitudinal infeed axis. An optimizing processor determines an optimized sawing orientation relative to the longitudinal infeed axis. A saw unit positioner selectively rotates the saw unit about a saw unit rotation axis so as to rotate the at least one saw into the optimized sawing orientation prior to sawing of the workpiece.

Abstract: The present invention relates to a teat cup liner for milking domestic animals such as cows and goats. The liner (1) comprises: an opening (8) into which an animal's teat (70) may be inserted; an outlet (6) for discharging milk from the animal; a teat engaging portion (10) with annular walls (7, 107) and a collapsible portion having relatively thinner inner walls (13, 113);  and sealing means (60, 66) for a teat cup shell (32) between which lies all of the collapsible portion (12) so a vacuum pressure may be applied to a teat cup assembly (30) to milk the animal. The distance from the opening (8) to a point (76) at which the collapsible portion (12) collapses is sufficient so that the collapsible portion (12) collapses substantially completely away from the animal's teat (70). The collapsible portion (12) has an elongate cross section, there being a tapering section (17) between the teat engaging portion (10) and the collapsible portion (12). The tapering portion has outer and inner walls (11, 111) the thickness of which tapers more gradually along a minor cross-sectional axis than along a major cross-sectional axis, so that the tapering section (17) may collapse gently on the teat (70) as the collapsible portion (12) collapses.

Title: Storage container for recorded media
Inventor: BELDEN DENNIS D JR
IPC: G11B33/04
Filed: 1998-08-17
Granted: 2008-10-28
Abstract: This invention relates to storage containers (10) for recorded media discs (32) that includes a centrally disposed hub (30) surrounded by, and spaced from, an outer wall (20). The hub includes a pair of resilient arms (64) that cooperate to retain the disc's centrally disposed hole. The outer wall contains a finger access recess (96) that is positioned to align with a reference plane (101) bisecting each resilient arm (64) of the hub (30). This arrangement allows the force generated by the user when removing the disc to be directly transmitted to the resilient arms, causing the resilient arms (64) to deflect and release the recorded media.

Title: An agile network protocol for secure communications with assured system availability
Inventor: MUNGER EDMUND C
IPC: H04L45/122
Filed: 1999-10-29
Granted: 2011-08-09
Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to "hopping" of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes. These techniques include a self-synchronization technique in which a sync field is transmitted as part of each packet, and a "checkpoint" scheme by which transmitting and receiving nodes can advance to a known point in their hopping schemes. A fast-packet reject technique based on the use of presence vectors is also described. A distributed transmission path embodiment incorporates randomly selected physical transmission paths.

Abstract: A method has been developed to detect the levels of apolipoproteins A-1 and B in saliva, which is correlated with the levels of HDL and LDL in serum, respectively. In unstimulated saliva, the ratio of Apo A to Apo B is correlated with the ratio of HDL to LDL in serum. Albumin can be used to normalize the sample for dilution. The high degree of correlation in combination with a simple, quick test that can be performed at the site of collection provides a coast effective, patient friendly means to monitor an individual's risk of heart disease. In the preferred embodiment, saliva production is stimulated by means such as breath mint or tart solution (such as lemon) and the effect of dilution controlled by reference to albumin. In the most preferred embodiment, the assay is an ELISA assay performed using t he Serex laminated strip format as described in U.S. Patent Nos. 5,710,009, 5,500,375, and 5,451, 504. These strips are advantageous since they serve as the collection and assay device.

Abstract: An input/output (I/O) controller (40) in an I/O system processes I/O requests from a host computer (15) to a plurality of I/O devices (80-86). The I/O controller (40) generates an interrupt to the host computer (15) and reports a plurality of completed I/O requests from the I/O devices (80-86) when at least one condition of the I/O system is met. A  first condition of the I/O system comprises a predetermined ratio between the total number of unreported I/O completions by the I/O  devices (80-86) and the total number of remaining I/O requests from the host computer (15). A second condition comprises the expiration of a timer, which starts when the number of remaining I/O requests left to process for any individual I/O device (80-86) reaches a predetermined minimum limit.
