Rheology modification of interpolymers of ethylene/alpha-olefins and articles made therefrom

ActiveUS20060199908A1Polymer sciencePolyolefin
Rheology modification of an ethylene / α-olefin interpolymer is achieved by blending the interpolymer with at least one branched polyolefin. The polyolefins can be homopolymers or interpolymers and have a branching index of less than 1. The ethylene / α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Rheology-modified ethylene / α-olefin interpolymer, i.e., the resulting polymer blends, can be extruded or molded into many useful articles, such as films, sheets, profiles, gaskets, foams, etc.

Fibers made from copolymers of propylene/alpha-olefins

A fiber is obtainable from or comprises a propylene / α-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams / cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481-1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers.

Flexible loyalty points programs

A disclosed a gaming machine includes an input mechanism with a non-physical contact data interface. The non-physical contact data interface may be capable of reading loyalty program data from a loyalty program instrument without contact between the loyalty program instrument and the non-physical contact data interface. The input mechanism with the non-physical contact data interface may be one of a bill validator, a bar-code reader and a Radio Frequency Identification (RFID) tag reader. The loyalty program instrument may be a substrate including at least one of a 1-D bar-code printed on the substrate, a 2-D bar-code printed on the substrate, a symbol printed on the substrate, alpha-numeric character printed on the substrate, a RFID tag embedded in the substrate, a RFID tag printed on the substrate and combinations thereof. The loyalty program instrument may be used to store an index to a record in a database or a portable data file.

Method of biochemical treatment of persistent pain

This invention relates to a method for the biochemical treatment of persistent pain disorders by inhibiting the biochemical mediators of inflammation in a subject comprising administering to said subject any one of several combinations of components that are inhibitors of biochemical mediators of inflammation. Said process for biochemical treatment of persistent pain disorders is based on Sota Omoigui's Law, which states: ‘The origin of all pain is inflammation and the inflammatory response’. Sota Omoigui's Law of Pain unifies all pain syndromes as sharing a common origin of inflammation and the inflammatory response. The various biochemical mediators of inflammation are present in differing amounts in all pain syndromes and are responsible for the pain experience. Classification and treatment of pain syndromes should depend on the complex inflammatory profile. A variety of mediators are generated by tissue injury and inflammation. These include substances produced by damaged tissue, substances of vascular origin as well as substances released by nerve fibers themselves, sympathetic fibers and various immune cells. Biochemical mediators of inflammation that are targeted for inhibition include but are not limited to: prostaglandin, nitric oxide, tumor necrosis factor alpha, interleukin 1-alpha, interleukin 1-beta, interleukin-4, Interleukin-6 and interleukin-8, histamine and serotonin, substance P, Matrix Metallo-Proteinase, calcitonin gene-related peptide, vasoactive intestinal peptide as well as the potent inflammatory mediator peptide proteins neurokinin A, bradykinin, kallidin and T-kinin.
