Patent CA-2552477-A1 (CA)
Title: Seed tube for seed metering apparatus
Inventor: JOHNSON CHAD M
IPC: A01C7/08
Filed: 1999-01-25
Abstract: A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defined an enclosed curved seed pathway extending between opposite ends of the tube. To promote control over the seeds passing through the tube, the tube has a smooth but decreasing cross-sectional configuration between the ingress and egress ends of the tube. The tube generally includes a front wall, a rear wall and a pair of side walls. The front wall is generally separated into an upper and lower portion. An opening in the front wall, which is provided to receive a monitoring device, is associated with the lower front wall portion. In addition, the lower front wall portion is stepped forward relative to the upper front wall portion. The enclosed seed pathway further includes a narrowed front edge extending in an upward direction from the egress end of the tube along some section of the front wall. The narrowed front edge enhances control over the seeds such that individual seeds passing through the tube and deposited to the ground have equidistant spacings between the seeds on the ground. The stepped forward arrangement for the lower front wall portion also allows a monitoring device to be used without disrupting the flow of seeds in the seed tube.

Title: Techniques for animating complex scenes
Inventor: GRASSIA FRANK SEBASTIAN
IPC: G06T17/00
Filed: 2004-05-10
Abstract: Techniques that enable users (e.g. animators) to accurately animate models in a scene without having to load all the models involved in the scene concurrently in computer memory. For a particular model that a user wishes to animate (702), only a minimal set of models involved in the scene that are needed for the particular model to evaluate correctly are determined (704) and loaded into computer memory (706). Additionally, if a particular model is to be unloaded from computer memory (772), then all models that depend, either directly or indirectly, on the particular model (724) and that are loaded in memory (726) are also unloaded from memory in order to avoid incorrect animation (728).

IPC: B60P7/08
Filed: 2004-05-17
Abstract: A self-tensioning tie down assembly and safety system for tightening the retaining straps securing cargo on a carrier. Retaining straps are connected to winches connected to the carrier. A ratchet system is used to tighten the winch. A two bar torque linkage has a ratchet arm connectable to the ratchet wheel of the winch via a socket and has a connector arm connected to an actuator. The actuator is connected to a pneumatic/electrical circuit and provides reciprocating linear motion thereby actuating the torque linkage. The torque linkage may be set in a tightening or loosening position. The required tension level of the retaining strap is pre-set. Pressure within the circuit drives the actuator thereby actuating the torque linkage which tightens the strap on the winch until the tension level is reached. Signals are sent to a display panel to indicate when a strap is loose.

Title: Signature protected photosensitive optically variable ink compositions and process
Inventor: AUSLANDER JUDITH D
IPC: C09D11/00
Filed: 2005-06-15
Abstract: Signature protected photosensitive optically variable (POV) inks are provided, which are capable of providing a unique signature in addition to other security features of POV inks. The inks contain at least two types of colorants, and a third, signature component and other ingredients to enable printing. A first colorant comprises a fluorescent dye and/or pigment emitting light within a characteristic emission band when excited by fluorescent-exciting radiation. A second colorant comprises a dye and/or pigment having a light absorption band at overlapping or longer wavelengths than the characteristic emission band of the first colorant in such a way as to result in a dark color. The third component is a fluorescent/phosphorescent rare earth composition. The inks give dark visible ink images, which also produce detectable coincident fluorescent and phosphorescent images. The inks can be used with detectors of red phosphorescence to achieve a new level of security in high speed sorting operations.

Title: Systems and method for virtual host name roaming and managing virtual ip addresses
Inventor: SIRJANI ABOLFAZI
IPC: H04L29/12
Filed: 2005-09-27
Abstract: The present invention relates to systems and methods for assigning a unique network identifier to one or more programs invoked on a computer, and providing a uniform network addressing scheme for a user accessing a network that is independent from the computer to which the user accesses the network.  The computer obtains a plurality of network identifiers and associates a first network identifier to a first program invoked on the computer and a second network identifier to a second program invoked on the computer. The program may be a user session hosted by the computer, an application or an application isolation environment. The computer through a network communication interface transmits the first network identifier with the network communication of the first program and transmits the second network identifier with network communication of the second program. Furthermore, a virtual host name can be assigned to and associated with the virtual IP address of the user, user session or a program the user is running. As the user accesses the network from different computers, the user can be assigned the same virtual host name and in some cases the same virtual IP address .

Title: Pif peptides biologic activities, site of action, and the antibody to detect pif
Inventor: BARNEA EYTAN R
IPC: C07K/
Filed: 2004-10-22
Abstract: A novel class of embryo derived peptides are described (Preimplantation factor) that were generated synthetically and were tested on peripheral blood immune cells and shown to block activated but not basal immunity, inhibiting cell proliferation and creating a TH2 type cytokine bias, in addition PIF  enhance endometrial receptivity by increasing adhesion molecules expression.  PIF biological activity appears to be exerted by specific binding to inducible receptors present on the several white cell lineages. PIF peptides, which are immune modulators therefore may have diagnostic and non toxic therapeutic applications in improving fertility, reducing pregnancy loss as well may be useful when administered for the treatment of autoimmune diseases and for prevention xenotransplants rejection. Further, polyclonal antibodies against PIF peptides were generated that serve for precise measurements of PIF in biological fluids. They document pregnancy presence and viability as well it helps for monitoring pregnancies at risk in humans as well as in farm and non farm animals, improving animal husbandry, where currently no specific pregnancy test exists. Also the PIF antibodies may have additional therapeutic properties for treatment of HIV, and malaria.

Title: Coumarin-based cyanine dyes for non-specific protein binding
Inventor: BERKELMAN THOMAS R
IPC: G01N33/00
Filed: 2005-12-08
Abstract: Protein dyes whose molecular structure is that of a coumarin moiety coupled to a quaternary ammonium heterocycle through a vinyl or polyvinyl linkage demonstrate the ability to associate with proteins in a non-covalent, non-specific manner at low pH, where the associated form displays a significantly higher fluorescence emission than the unassociated form. This makes the dyes useful as selective labels for proteins at the low pH and eliminates the need for the removal of extraneous components from the medium in which the proteins reside prior to detection.
