Abstract: A pressureless pipe and polymer composition for making such a pipe as well as the use of the polymer composition for pressureless pipes and supplementary parts, are disclosed. The polymer composition is characterized in that the polymer comprises a multimodal ethylene polymer including a copolymer of ethylene and a C4-C10 &agr; -olefin comonomer; the ethylene polymer has a total density of 953-958 kg/m3 and a MFR5 of 0.2-2.0 g/10 min; the ethylene polymer has a modulus of elasticity, determined according to ISO 178 of 1300-1700 MPa; the ethylene polymer has a resistance to slow crack growth, determined according to ASTM F 1473 of more than 1.5 hrs.

Abstract: The present invention relates to a polymer composition, comprising (i) a polypropylene-based matrix which comprises a polypropylene random copolymer prepared by copolymerization of propylene with an olefin comonomer, wherein the amount of olefin comonomer units is within the range of (0.2) wt % to (5) wt %, based on the weight of the polypropylene-based matrix, and (ii) an elastomeric copolymer of propylene and at least one olefin comonomer, the polymer composition having a storage modulus G1 at a loss modulus G?=5 kPa of G?(5 kPa)<(3100) Pa, measured at (220° C.).

Abstract: The system and method automatically ensures the enforcement of specific computer printer or multifunction peripherals (MFPs) printing features according to predefined rules based on characteristics such as the originating computer user name, the originating computer application, or the originating file extension. A Client Service installed in the computer printers and MFP devices periodically retrieves the actual active rules from a central Server Service and then automatically applies these rules to preferably every incoming document to be printed.

Abstract: A system for enforcing license terms between the creators of software applications running on virtual machines in network-attached embedded systems, and the users of these software applications, allows trial and demo versions of the software applications, where the user can install and use the software application for a limited time or number of executions, or with a limited feature set. When the software applications are purchased, the restrictions are lifted by the issuing of a unique license key eliminating the need for user-specific builds and redistributing of the software application. The system includes an application manager client in the embedded system designating a software application license request to a predefined web server; a webservice running on the web server that receives the request, validates the user-identifying data, issues a unique license key, and forwards this key to the application manager client; and a license data base containing validated user information.

Abstract: A device including a set of blades for removing dirt from underneath guard rails, with blades extending outward from the guard rail clean-out device in a cantilevered fashion to allow a user to extend the blades underneath and beyond the guard rails to remove dirt and gravel located under the guard rail while operating the device from the roadway.

Abstract: A needle bar for a tufting machine, comprising a main bar having a row of holes uniformly spaced at a coarse pitch, a multiplicity of contiguous segments fitted into a longitudinal location groove in one face of the main bar, each segment having a peg accommodated in one of said holes in the main bar and retained therein by a locking screw and a row of finer holes, disposed parallel to the holes in the main bar and uniformly spaced at a finer pitch than the holes in the main bar, and needles mounted in groups in the holes in the segments to extend away from the main bar and retained in said holes by locking screws, the number of needles in each group being equal.

Abstract: A looper mechanism for a tufting machine for producing loop pile fabric, comprising a looper bar carrying loopers which cooperate with respective needles of the machine and means for oscillating the looper bar to effect such cooperation, the looper bar having, in the side thereof facing the needles, a plurality of slots each of which accommodates, side by side, shank portions of a pair of loopers having hook portions facing the needles, the hook portion of one looper of the pair being coplanar with its shank portion and the hook portion of the other looper being offset from its shank portion by an amount equal to the spacing between the needles, and each pair of loopers being retained in its respective slot by a single clamping screw.

Abstract: A needle bar assembly for a tufting machine, comprising a member having a saw tooth surface, a row of needles disposed with their shanks in the recesses of said surface and clamps for clamping the needles in the recesses.
