Patent CA-2285299-A1 (CA)
Inventor: BARAK SWI
IPC: F04B43/12
Filed: 1998-02-24
Abstract: A peristaltic pump for propelling liquid through a flexible tube segment. The pump has a cam shaft which carries a plurality of cams each having a driving surface. The driving surfaces of adjacent cams are spaced at an angle to each other about the cam shaft. The pump also has a plurality of cam followers which are each reciprocal in a common direction perpendicular to the axis of the cam shaft. Each cam follower has a cam surface riding on the driving surface of a cam and a tube engaging surface for engaging the flexible tube segment. At least one of the cam followers is a restriction cam follower of which the tube engaging surface engages the flexible tube segment for a longer period than that of the other cam followers. The pump also has a motor for rotating the cam shaft whereby the cams cause the cam followers to each engage and occlude the flexible tube segment to form a propagating depression wave in the flexible tube segment for propelling liquid. The restriction cam followers prevent back flow of the liquid.

Patent CA-2293387-A1 (CA)
Inventor: WILSON MARK M
IPC: B60R25/04
Filed: 1998-06-01
Abstract: The present invention teaches a method for preventing the unauthorized reproduction of a remote unlock signal. In this scenario, the unauthorized reproduction occurs by jamming the receiver (120) from receiving the remote unlock signal while intercepting the remote unlock signal. Generally, the remote unlock signal is transmitted by a transmitter (110) to the receiver within a vehicle having a lock, wherein the receiver initiates an unlock command in response to receiving the transmitted remote unlock signal, and the vehicle lock being mechanically actuated by a key (115) or electronically initiated by the unlock command in a previous unlocking session. The method for preventing the unauthorized reproduction of a remote unlock signal comprises the steps of sensing whether the vehicle lock is being mechanically actuated by the key in the previous unlocking session, generating a flag if the vehicle lock has been mechanically actuated by the key, and disabling the receiver from initiating the unlock command in response to receiving the remote unlock signal transmitted by the transmitter if the flag is generated.

Abstract: The present invention provides methods for producing sialyloligosaccharides in situ in dairy sources and cheese processing waste streams, prior to, during, or after processing of the dairy source during the cheese manufacturing process. The methods of the present invention use the catalytic activity of .alpha.(2-3) trans-sialidases to exploit the high concentrations of lactose and .alpha.(2-3) sialosides which naturally occur in dairy sources and cheese processing waste streams to drive the enzymatic synthesis of .alpha.(2-3) sialyllactose. .alpha.(2-3) sialyloligosaccharides produced according to these methods are additionally encompassed by the present invention. The invention also provides for recovery of the sialyloligosaccharides produced by these methods. The invention further provides a method for producing .alpha.(2-3) sialyllactose. The invention additionally provides a method of enriching for .alpha.(2-3) sialyllactose in milk using transgenic mammals that express an .alpha.(2-3) trans-sialidase transgene. The invention also provides for recovery of the sialyllactose contained in the milk produced by this transgenic mammal either before or after processing of the milk. Transgenic mammals containing an .alpha.(2-3) trans-sialidase encoding sequence operably linked to a regulatory sequence of a gene expressed in mammary tissue are also provided by the invention.

Patent CA-2303352-A1 (CA)
Title: Natural coloring and antimicrobial agents from plants
Inventor: SHANBROM EDWARD
IPC: A23L1/275
Filed: 1998-09-16
Abstract: An active coloring concentrate can be prepared from the juice of cranberry and other fruits or vegetables by treating juice or homogenate with an appropriate binding matrix. Assorted ion exchange resins such as cholestytamine are effective binding matrices, but the currently preferred material is a food grade of cross-linked polyvinylpyrollidone. When appropriate binding matrices are used to concentrate active materials from cranberry, a colored solid is produced. This substance shows significant antibacterial and anti-viral properties. It can be readily consumed as a therapeutic or nutraceutical, used as a coloring agent, or it can be used topically. An additional advantage of the present method is that significant amounts of active concentrate can be produced from cranberrry presscake which is normally a waste material.

Title: Float current measuring probe and method
Inventor: MAILLOUX MICHEL
IPC: G01R15/18
Filed: 2000-04-26
Abstract: A float current probe measuring a float current flowing in a conductor comprises a core adapted to be magnetically coupled to the conductor. Excitation and field cancellation windings are magnetically coupled to the core. A detector detects when energy in the excitation winding reaches a predetermined threshold corresponding to a saturated core condition. A timer measures first and second delays needed to saturate the core as a result of the excitation winding being energized through a switch circuit in the forward and reverse polarity successively. A computing unit determines a magnetic field induced by the conductor based on the first and second measured delays. The field cancellation winding is energized by a current source with a current level and direction as a function of the computed magnetic field, to cancel the magnetic field induced by the conductor. The current level is representative of the float current in the conductor.

Title: Method of generating a display for a dynamic simulation model utilizing node and link representations
Inventor: BANGS ALEX L
IPC: G06F9/44
Filed: 1998-10-23
Abstract: A method of generating a display, or representation, of a simulation model within a graphical user interface (GUI) is described.      The simulation model includes a number of objects, which may include state, function, link and modifier objects. The method commences with the display of node representations for at least first and second objects. Thereafter, a link representation, which represents an underlying link object, is selected from a predefined set of link representations to represent a desired relationship condition between the first and second objects. Each link representation of the set is associated with a distinct relationship condition.      Each relationship condition may further be defined in terms of an underlying equation. Thereafter, the selected link representation is shown to extend between the respective node representations representing the first and second objects. Thus, the type of relationship condition which exists between the first and second objects is apparent from the link representation which extends between the relevant node representations.
