The present invention relates to novel bioabsorbable polymeric compositions based upon AB polyester polyether or related diblocks and triblocks. Compositions according to the present invention may be used in medical applications, for example, for reducing or preventing adhesion formation subsequent to medical procedures such as surgery, for producing surgical articles including stents and grafts, as coatings, sealants, lubricants, as transient barriers in the body, for materials which control the release of bioactive agents in the body, for wound and bum dressings and producing biodegradable articles, among numerous others.

Polyethylene having a broad molecular weight distribution is extruded in pellet form using a pelletizing extruder having one or more zones essentially filled with the polyethylene and two or more zones partially filled with the polyethylene. The polyethylene is fed into the extruder at a temperature sufficient to melt the polyethylene, and a mixture of an inert gas and oxygen is fed into at least one partially filled zone of the extruder with the exception of the feed zone. The mixture contains about 1 to about 21% by volume oxygen based on the volume of the gas mixture.

A method of fabricating plastic objects having an insert of Lenticular lens material integrally bonded or otherwise attached therein. In one embodiment, the method is used to fabricate a container, such as a conical cup, by first manufacturing or providing a sheet of Lenticular material comprising layers of lens material and optical ridges and grooves and an ink layer printed on the flat side of the lens material. To protect the ink from the heat of molten or moldable plastic during later plastic processing, a thermally protective substrate is attached or bonded to the ink layer by using adhesives to attach a plastic substrate or by coating the ink with coating materials that thermally protect the ink from high temperatures. In one embodiment, the protective substrate is applied in a two step process of first placing a plastic hot melt onto a polyester or other material release liner and, after cooling of the hot melt, using heat and pressure to laminate or bond the hot melt plastic to the ink and then removing the liner. Lenticular inserts are cut out of the Lenticular material sheets and the inserts are positioned within a mold where the container is formed by injection, blow, or other molding process. In this step, the substrate acts as a bonding surface as it contacts the molten plastic, melts, and then cools forming a bonding interface with the plastic used to form the container.

The present invention relates to novel polymeric compositions based upon An(BCB)An polyester / polyether multi-blocks. Compositions according to the present invention exhibit unexpectedly exceptional reverse thermal gellation properties and in certain cases, relatively low viscosities at approximately room temperature and extremely high viscosities at temperatures above room temperature (preferably at approximately physiological or body temperature, i.e., within a temperature range of about 32-40° C.). Compositions according to the present invention may be used advantageously in applications which make use of their reverse thermal gellation properties. Preferred applications for use of the present compositions include, for example, medical applications which make advantageous use of the inherent composition characteristic of being of relatively low viscosity at room temperature and much higher viscosity at elevated temperatures, especially body temperature.

A system and method for conducting verifiably correct auctions that preserves the secrecy of the bids while providing for verifiable correctness and trustworthiness of the auction is disclosed. Some of the elements of the method and apparatus are that the auction operator accepts all bids submitted and follows the published rules of the auction. In one embodiment, the bids are maintained secret from the auctioneer and all bidders until the auction closes and no bidder is able to change or repudiate her bid. In another embodiment, the auction operator computes the auction results and publishes proofs of the results' correctness. In yet another embodiment, any party can check these proofs of correctness via publicly verifiable computations on encrypted bids.

A sectional doorpanel (P, P′; P″) having a facer (50; 94; 114), a backer (52; 96; 116), a core (54; 98; 117) interposed between the facer and the backer, the backer including at least one protruding element (60A, 60B) extending outwardly therefrom and longitudinally thereof, and a reinforcing member (66, 76) positioned longitudinally along the protruding element and a reinforcing strip (90; 112, 113) positioned adjacent one of an upper edge (112) and a lower edge (113) of the panels and extending longitudinally thereof.

A new heating cable is described. The heating cable is comprising between seven and two hundred metallic monofilaments of a first type which are acting as electrical conductors to generate heat. The metallic monofilaments of a first type are having a diameter ranging from 30 μm to 100 μm. The metallic monofilaments of a first type are having a substantially round cross section. The metallic monofilaments of a first type are comprising a steel layer with a chromium content of less than 10% by weight. The heating cable is having an electrical resistance ranging between 0.1 Ω / m and 20.0 Ω / m when measured at 20° C.

A plasterboard comprises a gypsum matrix having a polymeric additive distributed therein in an amount of at least 1 wt % relative to the gypsum, the gypsum matrix further having a first group of fibres and a second group of fibres embedded therein, wherein the fibres of the first group of fibres have an average length that is at least three times the average length of the fibres of the second group of fibres.

A method and device for estimating one or more transmission properties of a telecommunication transmission line. At least one signal is sent on the line, the at least one signal including at least two frequencies for which the absolute value of the line propagation constant times the line length is less than π, and a resulting signal is received. An estimate of at least one transmission line property is then determined by examining the relationship between the sent and resulting signal or signals. The process may be repeated, if necessary. The estimate determination may also be repeated one or more times, with each successive estimate preferably using for the determination only those frequencies for which, as previously estimated, the absolute value of the line propagation constant times the line length is less than π.
