Title: Phosphatized amine chain-extended epoxy polymeric compounds
Inventor: SIMEON MARIE EDLA
IPC: C09D151/08
Filed: 1998-09-21
Abstract: This invention provides a novel phosphatized polymeric product which is formed by: (a) forming an amine-extended resinous composition having unreacted epoxy groups by mixing, under free-radical initiated polymerization conditions, a polymerizable, ethylenically unsaturated monomeric component and a polyepoxide component; and (b) phosphatizing at least a portion of the unreacted epoxy groups of the resinous composition. The present invention also provides novel coating compositions containing the aforedescribed polymeric product. While these novel coating compositions have a number of different uses, they are particularly useful for application to metal substrates such as can end stock since they result in a cured film which has excellent performance properties such as flexibility and extensibility, adhesion, resistance to boiling liquid pack tests and boiling water taste test results.

Title: Ultrasound bubble recognition imaging
Inventor: MORGAN KAREN ELIZABETH
IPC: A61K49/00
Filed: 1998-09-17
Abstract: In a method of identifying gaseous bubbles in a liquid, an ultrasound contrast agent is introduced into the liquid so as to form gaseous bubbles in the liquid. A first ultrasound pulse centered at a first frequency is directed onto the bubbles so as to cause the bubbles to undergo a first oscillating size change and produce a first oscillating echo signal corresponding thereto.  The first oscillating echo signal produced by the bubbles is detected, and the bubbles are identified based upon the detected first echo signal.

Inventor: LU DAOZHENG
IPC: G10L21/0208
Filed: 1998-06-09
Abstract: A member of an audience of a program to which a receiver is tuned is identified by a system which includes first and second microphones, a noise cancellation unit, and a voice recognition unit. One of the first and second microphones picks up relatively more of a voice signal from the member of the audience, and the other of the first and second microphones picks up relatively more of a sound signal from the receiver. The noise cancellation unit substantially eliminates the sound signal from the voice signal. The voice recognition unit identifies the member from the member's voice signal.  The first and second microphones, the noise cancellation unit, and the voice recognition unit may be housed in a hand held housing or in a table top housing. The system may also include a passive people meter to passively identify the member, and a program to identify the program or channel to which the receiver is tuned.

Title: Membrane for tangential filtration and manufacturing process thereof
Inventor: RUSCHEL BERND
IPC: B01D61/08
Filed: 2000-08-03
Abstract: The thickness (e) of the separation layer (4) decreases in the direction of flow (f) of the fluid. The membrane has an inorganic rigid porous support (2) defining at least one circulation channel (3) for the fluid to be treated to circulate in a given direction (f). The surface of the channel is covered with at least one layer (4) for separating the fluid, with a fraction called the permeate passing through the layer and support. The thickness of the separation layer decreases continuously or in steps in the direction of flow. The steps each have the same length in the direction of flow. The channel has a cylindrical or polygonal section. Process for making such a membrane, by covering the surface of the channel with a separation layer of decreasing thickness in the direction of flow of the fluid. The thickness decreases as a function of the gradient of the fluid pressure so the flow of permeate is constant along the channel. The length of each channel is divided into sections of equal length and the surface of each channel is covered with a separation layer by depositing it, starting with the section at the inlet end of the channel and reducing the length for each successive deposit. Alternatively, the porous support is placed vertically and each channel is filled with a suspension of the deposit of the separation layer and the channel is emptied progressively so the deposit time for one end of the channel is greater than that of the other.

Abstract: Les fixations pour ski de fond qui existent actuellement sur le marché sont adaptées exclusivement pour des bottines de ski et n'offrent pas la possibilité de skier avec des bottes d'hiver conçues pour des conditions climatiques extrêmes.  Aussi, le marché actuel offre un adaptateur se vissant directement et entièrement sur le ski, ce qui n'est pas très efficace quant à la stabilité du pied et empêche l'utilisation de bottines de ski de fond par l'absence de fixation. La présente invention consiste en un adaptateur se fixant à la fixation du ski et permettant de chausser des bottes confortables et chaudes pour faire des expéditions de longue durée et à des températures très froides tout en offrant la même flexibilité qu'une bottine de ski de fond et une meilleure stabilité de la partie arrière du pied du skieur, et ce, sans compromettre l'usage des mêmes skis avec bottines usuelles.
