Patent CA-2458811-A1 (CA)
Title: Selection of cells expressing heteromeric polypeptides
Inventor: BIANCHI ALLISON A
IPC: C12P21/08
Filed: 2002-09-20
Abstract: The invention utilizes selectable markers that can exist as two or more subunits that when expressed together will interact, thereby providing a selectable activity. The individual subunits do not have significant selectable activity alone, but do provide selectable activity when co-expressed with their counterpart subunit. The optimal activity of the subunits can depend upon their interaction, and as such can be facilitated by interaction domains. Such interaction domains can be endogenous to the subunit or it can be heterologous to the subunit.

Title: Method and separating module for separating particles from a dispersion, particularly blood corpuscles from blood
Inventor: FIEDLER WOLFGANG
IPC: B81B1/00
Filed: 2002-09-14
Abstract: A method for separating particles from a fluid disper-sion, particularly for separating corpuscular components from biological samples, above all from blood. A  separating module suitable for performing the method has a substrate (5) with flow channels (3), comprising a feed channel (9) for supplying the dispersion to a junction (10), a first drain channel (11) for draining fluid having a reduced particle concentration away from the junction (10), and a second drain channel (12) for draining fluid having an increased particle concentration away from the junction (10). The fluid flows so much faster in the second drain channel than in the first drain channel (12) that due to the different flow speeds the dispersed particles preferentially flow at the junction (10) further in the second drain channel (12).

Abstract: An apparatus and method for manual operation of an actuator is disclosed. A mechanical override includes a housing coupled to the actuator, a drive ring, and a shaft extending through a bore of the housing. The drive ring rotationally keys to the bore such that the drive ring is capable of axial movement within the bore in response to automatic operation of the actuator. A backstop limits axial movement of the drive ring during manual operation. A thread located on an external portion of the shaft threads to the drive ring. In the manual operation, the shaft rotates through the drive ring imparting axial movement to the shaft capable of moving a valve between a first position and a second position. The override provides visual indication of the valve position during both automatic and manual operation. The backstop may be an insert that selectively permits movement of the shaft to a failsafe position in response to a temperature or pressure change.

Inventor: KHAJEPOUR AMIR
IPC: B25J17/02
Filed: 2003-07-09
Abstract: The present invention provides parallel, cable based robotic manipulators, f or use in different applications such as ultra high-speed robots or positioning devices with between three to six degrees of freedom. The manipulators provi de more options for the number of degrees of freedom and also more simplicity compared to the current cable-based robots. The general structure of these manipulators includes a base platform (24), a moving platform or end effecto r (22), an extensible or telescoping central post (26) connecting the base (24 ) to moving platform (22) to apply a pushing force to the platforms. The centr al post (26) can apply the force by an actuator (active), or spring or air pressure (passive) using telescoping cylinders. The robotic manipulators use a combination of active (28) and passive tensile (cable) members, and collapsible and rigid links to maximize the benefits of both pure cable and conventional parallel mechanisms. Different embodiments of the robotic manipulators use either active cables only, passive cables only, or combinations of active and passive cables. An active cable is one whose leng th is varied by means of a winch (30). A passive cable is one whose length is constant and which is used to provide a mechanical constraint. These mechanisms reduce the moving inertia significantly to enhance the operationa l speed of the robots. They also provide a simpler, more cost effective way to manufacture parallel mechanisms for use in robotic applications.
