Assignee:

Guardian Industries, Inc. - Auburn Hills MI

International Classification:

B32B 2708

US Classification:

428 31, 428421, 428520, 428522, 428523

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a thermoplastic reactive terpolymer of ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) which adhesively bonds the substrate and clear coat layers one to another. Most preferably, the tie layer is a blend of E-MA-GMA and a tackifier (e. g. , a C6-C8 cycloaliphatic hydrocarbon resin). The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer between the substrate and clear coat layers. The tie layer most preferably includes a first layer adjacent the thermoplastic substrate layer which is comprised of a polyolefin, and a second layer adjacent to the clear coat layer which is comprised of a polyamide. Most preferably, the substrate layer is TPO and the clear coat layer is PVF. The laminates may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a maleic anhydride grafted styrenic block copolymer which adhesively bonds the substrate and clear coat layers one to another. Advantageously, the tie layer includes a blend of the styrenic block copolymer and a diamine, especially 2-methylpentamethylenediamine. The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a branched or linear styrenic block copolymer which adhesively bonds the substrate and clear coat layers one to another. Advantageously, the tie layer includes a blend of the styrenic block copolymer and a tackifier resin, preferably a terpene resin. The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Appl. No.:

12/208272

Inventors:

Stanley E. Zocholl - Holland PA, US

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

H02H 7/08

US Classification:

361 25, 361 23, 361 31, 361 33, 318445, 318461, 318455, 322 34

Abstract:

An accurate slip calculation for providing monitoring and protection to an electric motor. The slip calculation is made using a minimum value of stator resistance as the initial stator resistance, where the minimum value of stator resistance is the minimum value of stator resistance calculated during an initiation period of the motor. The initiation period may be a predetermined time period or a predetermined number of cycles during the motor startup. The initiation period may start after a predetermined settling time or after a predetermined condition is met.

Assignee:

JP Laboratories, Inc. - Middlesex NJ

International Classification:

G03C 173

US Classification:

430332

Abstract:

Described is a radiation sensitive imaging film containing a heat fixable radiation sensitive element, e. g. , a diacetylene, of the formula: R--C. tbd. C--C. tbd. C--R', where R and R' are, e. g. , both --CH. sub. 2 --O--CONH--(CH. sub. 2). sub. 5 CH. sub. 3. After exposure to X-radiation during diagnostic or X-ray therapy, the resulting image can be permanently dry fixed by a short heating step and then stored for a long period. Processes for making the film, new binder-convertor systems, and a device incorporating the film are described as well as other imaging, diagnostic and therapeutic methods utilizing the film in high energy radiation applications in the health care field.

International Classification:

B29C 7100

US Classification:

216 83

Abstract:

There is disclosed a process of etching the surface of polymeric materials made of polymers having at least one oxidatively degradable functionality which comprises treating said surface with a solution of at least one member of the etchant group consisting of nitronium, nitrosonium ions and complexes thereof, in a solvent containing less than 40% by weight of water and nitroacidium ions and complexes thereof. The process further comprises use of cosolvents and swellants. It also includes pre and post etching steps directed to the preparation of the surface for etching and removal of the etchant respectively.
