Abstract: The present invention includes a multicomponent structure comprising at least two components having a tie layer or adhesive layer directly between them, the tie layer comprising at least one olefin unsaturated ester copolymer and at least one photoinitiator and optionally a crosslinking enhancer. The tie layer is preferably irradiated with sufficient actinic radiation to result in increased interlayer adhesion strength between the two components as compared with the interlayer adhesion strength before treatment with the actinic radiation or between the components having a tie layer of the same composition except without the added photoinitiator or crosslinking enhancer. Without the photoinitiator, optionally crosslinking enhancer, and radiation the interlayer adhesion of the components is preferably less than 55 N/m. At least one of the components (first component or layer) preferably comprises a halopolymer, more preferably vinylidene chloride polymer, most preferably at least a majority of a vinyl idene chloride polymer. In another embodiment, at least one component exhibits interlayer adhesion strength similar to vinylidene chloride polymers.  The structure optionally is or comprises such structures as a multilayer film, bag, or package, a lined or composite pipe, or other structure having more than one component. The tie layer is advantageously irradiated with an amount of UV light effective to increase the adhesion strength between the first and second components.

Title: Active dose reduction device and method
Inventor: NEYSMITH PETER FRANCIS
IPC: G01R19/00
Filed: 2005-07-05
Abstract: An active dose radiation device and method decreases the amount of x-rays which may be generated by an x-ray tube following termination of the x-ray exposure. One component of the x-ray system is connected to the device which has a plurality of electronic cells that can be overvoltaged from a first state, where they are less conductive, to a second state, where they are highly conductive. A voltage pulse generator overvoltages a first cell in the plurality of cells at termination of an x-ray exposure. Overvoltaging the first cell causes a cascading effect which eventually overvoltages all of the cells and changes the state of the cells from the first less conductive state to the second highly conductive state. In the second highly conductive state, the cells can conduct current from at least one component of the x-ray system to ground thereby reducing x-rays generated by the x-ray tube and reducing the x-ray dosage from the imaging system after the x-ray exposure has been completed. The plurality of cells automatically reverts to the first state once current passing through the cells decreases below a threshold current level. The plurality of cells are connected to only the anode side 26 or the cathode side 38 of the x-ray imaging device in order to discharge energy from only one side to ground which results in a sufficient decrease in the voltage across the x-ray tube to prevent generation of active dosage of x-rays which may penetrate the patient.

Title: Clamping tool, especially a clamping clip, clamping rod or clamping bench
Inventor: BLANK STEFAN
IPC: B25B5/16
Filed: 1998-06-26
Abstract: The invention relates to a clamping tool, especially a clamping clip with a clamping area between a first mobile clamping jaw (1) which rests at the end of a pull or slide rod and a fixed second clamping jaw (2) which rests on a housing. The inventive clamping tool also comprises a pivoting handle (10). Said handle (10) is located opposite the fixed clamping jaw (2) in relation to the longitudinal extension of the pull rod and next to a grip situated on the housing side. As the handle (10) is displaced against the grip, the pull rod is displaced progressively in such a way that the first mobile clamping jaw is moved towards the second fixed clamping jaw, any back pressure being locked. The clamping tool also has a release lever for releasing the back pressure lock. This release lever rests on the housing. In order to increase the scope of application of the inventive clamping clip, both the handle (10) and the release lever (15) are located on the side of the grip (33) facing away from the clamping area (1, 2), the lever transmission ratios are adjusted as the clamping force increases for smaller displacement paths and the mobile clamping jaw can be moved back progressively by operating the release lever (15).

The non-stretched laminate film is cooled by a cooling roll having a temperature within a limited range and then successively and biaxially stretched. With such a production method, the biaxially stretched, multi-layered polyamide film is excellent in the gas barrier properties, pinhole resistance, flexibility, and impact resistance.

Title: Combination of polymer slurry types for optimum pipeline drag reduction
Inventor: HARRIS JEFFREY R
IPC: C08K9/00
Filed: 2006-06-06
Abstract: A method of extending or broadening the effective time of drag reduction for a drag reducing agent in a pipeline may be custom-designed by combining two drag reducing slurries or other drag reducing products made by different or alternative techniques. For instance a precipitation polymer slurry derived from polymer precipitation where the polymer dissolves relatively quickly can be combined with a ground polymer slurry derived by grinding bulk polymer (ground at either cryogenic or non-cryogenic temperatures), or by using other size reduction techniques, where the latter polymer dissolves relatively slowly. In one non-limiting embodiment of the invention, bulk polymer may be ground directly into a precipitation polymer slurry to make the ground polymer slurry and blend the slurries simultaneously, where the precipitation polymer slurry serves as an anti- agglomeration agent.

Abstract: The base body of an object provided with a coating (5; 21) can be metallic or non metallic. The base body is preferably the base body of a kitchen appliance. At least one layer of the coating (5; 21) comprises a coating material with a fibrous material which deforms the surface of the coating with spatial frequency fractions ranging from 3µm -1 to 1000µm -1. If the surface of the layer is a free coating surface, the roughness generated by the spatial frequency fractions generates a self-cleaning effect and/or improves an anti-adhesive effect. If the surface of the layer is a boundary surface to another layer, the layers mesh, producing an improved adherence between the layers.
