Title: Method of preparing aqueous dispersions of ethylene/.alpha.,.beta.-unsaturated carboxylic acid interpolymers
Inventor: ROWLAND MICHAEL E
IPC: C08L33/02
Filed: 1992-01-24
Granted: 2004-05-04
Abstract: Aqueous dispersions of ethylene/~,.beta.-unsaturated carboxylic acid interpolymers (e.g., random ethylene/acrylic acid interpolymers) are formed using a mixture of bases at a concentration of at least 0.2 equivalents of base per mole of .alpha.,.beta.-unsaturated carboxylic acid. The dispersions have at least 10 weight percent dispersed solids and not more than 1 weight percent of the initial polymer in non-dispersed form. Preferred bases for use in forming the dispersions are ammonium hydroxide and/or alkali metal hydroxides. A mixture of ammonium hydroxide and potassium hydroxide is especially preferred for forming the dispersions with ethylene/acrylic acid interpolymers at an ammonium hydroxide: acrylic acid molar ratio of 1:1 and a potassium hydroxyde: acrylic acid molar ratio in the range of 0.6-0.8:1. The dispersions are particularly useful in forming thin coatings of adhesive on substrates, such as paper and metal foil, using conventional techniques.

Granted: 1996-10-22
Abstract: A strip baggage tag (1) is formed in endless or roll form for facilitating machine printing. It includes a tag part (6) which is to be fastened to a bag, and a control section (7). The control section (7) comprises a tear-off part (4'') which can be detached from the tag part (6) along a transversely extending separation line (8). Both the tag part (6) and the tear-off part (4'') have, on their back, an adhesive area (10) which is coated with pressure-sensitive adhesive and extends on both sides of the separation line (8). The adhesive area (10) is covered by a single-piece lower-web section (5) bearing a separation-active coating, for instance of 8ilicone, the width of which section corresponds to that of the upper web (4). The lower-web section (5) has, in the region of the adhesive area associated with the tear-off part (4''), a separation-inactive partial region (11) which permits a firm bonding. This partial region (11), which may be made separation-inactive for instance by corona treatment, forms an attachment bridge to make a firm connection between the web section (5) and the tear-off part (4''), both of which together form the control 8ection (7) which can be adhered to a plane ticket jointly, after exposure of a part of the adhesive area (10) for identifying an article of baggage.

Title: Spatially scalable video coding facilitating the derivation of variable-resolution images
Inventor: PURI ATUL
IPC: H04N7/50
Filed: 1993-05-13
Granted: 1999-03-23
Abstract: An adaptive technique for encoding and decoding which facilitates the transmission, reception, storage, or retrieval of a scalable video signal. The invention allows this scaling to be performed entirely in the spatial domain. In a specific embodiment of the invention this scaling is realized by adaptively encoding a video signal based upon a selection taken from among a multiplicity of predictions from previously decoded images, and a selection of compatible predictions obtained from up-sampling lower resolution decoded images of the current temporal reference. A technical advantage of the invention is that both the syntax and signal multiplexing structure of at least one encoded lower-resolution scale of video is compatible with the MPEG-1 standards.

Granted: 2000-10-17
Abstract: ABSTRACT         The invention provides water swellable wound dressing materials comprising from 5% to 50% of an alginate ester of a C1-C6 polyhydric alcohol; from 50% to 95% of a humectant consisting of one or more C1-C6 monohydric or polyhydric alcohols; and from 0% to 30% of water, the percentages being calculated by weight based on the weight of the material when anhydrous. The preferred alginate ester is propylene glycol alginate (PGA). The materials swell but do not dissolve in cold or warm water. Insolubility is achieved by the addition of polyvalent cations such as calcium ions, or by covalent cross-linking of the PGA, or by adding from 10 to 35% by weight of a water-swellable polysaccharide such as gelatin, or by adding from 5% to 20% by weight of a cationic polymer such as chitosan.

Title: Video merging employing pattern-key insertion
Inventor: HANNA KEITH JAMES
IPC: H04N5/272
Filed: 1992-09-10
Granted: 2001-11-20
Abstract: Disclosed is a technique for deriving a composite video image by merging foreground and background video image data supplied from a plurality of separate video signal sources employing pattern-key insertion, rather than prior-art color-key insertion, for this purpose.      Pattern-key insertion involves replacing a first pattern (202) in a video scene (204A) with a second pattern (204B). This is accomplished by first detecting the first pattern (202) in the video scene and estimating the pose of this detected first pattern with respect to a reference object in the video scene. The second pattern is then geometrical-ly transformed using the pose estimate of the detected first pattern. Finally, the detected first pattern is replaced with the geometrically-transformed second pattern.

Inventor: YAMASHITA KAZUO
IPC: H03B1/04
Filed: 1995-01-10
Granted: 1999-11-02
Abstract: The time constant determined by a high-speed time constant circuit (32) is suitable for high-speed pulling of an output frequency (f0), and the time constant determined by the low-speed time constant circuit (33, 34) is suitable for stabilization of the output frequency (f0) at a corresponding value and suppression of a spurious output frequency.       When the output frequency (f0) is switched from (f a) to (f b), for example, the output frequency (f0) is switched by setting the frequency division ratio (n) in the state in which the switch (S a) is ON, while the switch (S b) is OFF.      Simultaneously, the switch (S a) is turned off, and after the output frequency (f0) is stabilized, the switch (S b) is turned on. The speed of switching the output frequency (f0) is heightened and a spurious output frequency after switching the frequency is suppressed without using an A/D converter or a D/A/ converter having high accuracy.
