Patent MX-9101156-A (MX)
Inventor: WINKLE MARK ROBERT
IPC: C08J5/18
Filed: 1991-09-19
Abstract: This invention is directed to a method for eliminating or reducing pinhole defects in cataphoretically deposited films without interfering with the electrolysis of water needed for electrodeposition. The method comprises decreasing the evolution of hydrogen gas at the cathode by adding, to the electrodepositable composition, a compound which is reduced by the hydrogen produced at the cathode during the electrodeposition. The hydrogen reacts with this non-gaseous compound rather than becoming hydrogen gas and forming bubbles which lead to pinhole defects.

Title: Process to handle containers with caps.
Inventor: CORDERO JORGE LUIS LEIJA
IPC: B65D25/22
Filed: 1996-09-12
Abstract: The present invention describes a process to industrially handling containers, by means of a hook and/or ringlet mechanical adhesive, which is placed on the external surface of caps, plugs, or the containers body, on one hand; and, on the other hand, a hook and/or ringlet mechanical adhesive, which is complementary to that placed on the caps or containers, and disposed on a predetermined point of the handling system which is to be employed to transport containers. The handling systems are the only movable part of this industrial cargo handling technique, since they are displaced from one place to another along with the load adhered thereon by means of said mechanical adhesive. What is basically novel about it, is to mould a non-sticky mechanical and physical adhesive system on the external surface of caps or containers which does not easily loose its adhesive properties and supports great weights. This physical-mechanical adhesive can be molded while manufacturing the caps or containers out of plastic, but it can also be applied after these pieces are manufactured, by means of self-adhesive tapes.

Title: Oximino silane terminated polymers and elastomers formed therefrom.
Inventor: FLACKETT DALE RUSSELL
IPC: C08G63/91
Filed: 1995-05-03
Abstract: Oximinosilane terminated polymers which are cured at room temperature to become stable elastomers. The polymers have hydrolyzable ketoximino silyl group at each end of each molecule and are prepared by reacting a hydroxyl-terminated liquid polymer with an organic diisocyanate to produce an isocyanate terminated prepolymer. The resulting prepolymer is then converted into a mercaptan terminated polymer either by reacting with a mercapto alcohol or by reacting with an olefinic alkylene alcohol or amine to give an olefin-terminated polymer which is then reacted with a dimercaptan. When the mercaptan terminated polymer is reacted with a vinyl oximino silane or a vinylalkoxyoximino silane, a silane terminated liquid polymer is obtained. Such polymers have improved elongation, moisture resistance, tensile and tear strength properties in adhesive, coating and sealant formulations.

Title: Rate control for stereoscopic digital video encoding.
Inventor: CHEN XUEMIN
Filed: 1997-07-02
Abstract: Rate control in a stereoscopic digital video communication system is accomplished by modifying the quantization level of P or B-frame data in the enhancement layer depending on whether the frame is temporally predicted (from the same layer) or disparity predicted (from the opposite layer). The invention can maintain a consistent image quality by providing additional quantization bits for disparity-predicted P-pictures, for example, where a P-frame may be encoded from a B-frame in the enhancement layer. The selected quantization level corresponds to an overall bit rate requirement of the enhancement layer. For disparity predicted P-frame, the quantization step size is modified according to the activity level of the frame being encoded in the enhancement layer, or of the reference frame, whichever is greater. Also, image quality is improved and frame freeze up is prevented during editing modes such as fast forward and fast rewind which require random access to the picture data. When the reference frame in the base layer in the first frame of a group of pictures (GOP), the corresponding enhancement layer frame will be encoded as an I or P frame instead of as a B frame to improve image quality and eliminate or reduce error propagation during random access.
