Abstract:
A method of applying protective sheeting (9) of polymer material to a pipeline (1) extending along a longitudinal axis (A1) and having a cutback (8) bounded at opposite axial ends by two end portions (10) of respective protective coatings (5) of polymer material, the method including directly heating the free faces of the end portions (10); extruding and simultaneously winding about the pipeline (1) a protective sheeting (9) wide enough to cover the cutback (8) and the end portions (10); and compressing the protective sheeting (9) against the pipeline (1), the end portions (10) included.
Abstract:
Method and apparatus for manufacturing an optical component may include mixing two precursors of silicone (210a, 210b), opening a first gate of an optic forming device (202), moving the silicone mixture from the extrusion machine (201) into the optic forming device, cooling (204) the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating (205) the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Abstract:
An apparatus and method are provided for making a conduit divided into channels by one or more strip-shaped substrates. The channels may be used for cables, such as fiber optic cables, coaxial cables, electrical cables, electrical wiring, and the like. Each divided conduit provides channels that allow e.g., cables to be pulled through without snagging or excessive heat build-up due to friction. In addition, the divided conduits do not allow contact or alternation losses between adjacent cables in other channels of the conduit.
Abstract:
Method of insertion and welding of an emitter (4) in a drip irrigation pipe (1) during the manufacturing thereof. The emitters bear protrusions (5) with the possibility of cutting off of the protrusions and parts of the pipe which cover them, creating the water outlet openings. The emitters are inserted in a row into the interior of the pipe and preferably in a system of two vacuum baths with fix calibrators bearing slots and openings (11, 11a, 13, 27) for the swelling of the pipe, the welding of the emitter and its protrusions (5), occurred in three discrete phases, supported by an elastic wheel (14) : a) The protrusions (5) of the emitter insert in to the clearance (11,11a) between the two parallel bars (24) swelling the walls of the pipe. b) The emitter with the pipe moves horizontally compressed between the elastic wheel (14) and the internal rod (6,6a) and welds into the pipe. c) The pipe with the welded emitter passes, supported by the elastic wheel (14), through a longitudinal slot (27,13) where a bilateral compression exerts onto the swollen walls of the pipe.
Abstract:
Device and method are disclosed for feeding drippers into a produced dripping line in speeds as high as 1800-2000 drippers a minute. The drippers are fed into the production line by a cylindrical feeder equipped with a helix worm made on its cylindrical face, which is adapted to engage the helix into a respective recession or protrusion made on a dripper, and to linearly forward it toward a dripping pipe production section while providing accurate control on the speed of movement of the dripper and the spacing between each two consecutive drippers in the produced pipe. The use of a helical worm to engage the drippers provides smooth and gradual mechanical engagement of the feeding device with each dripper, thus ensuring silent and non- vibrating assembly even when in very high production speeds.
Abstract:
A method and apparatus is disclosed enabling a length of wood (20) such as a post (40) to be encapsulated in a coat such as plastic (110). The method involves placing and caps (31, 33) at the ends of the post (40) and coating the resulting assembly. The method also provides for encapsulating a plurality of posts in a production line.
Abstract:
Drip irrigation pipe (10) comprises drip irrigation emitter units (12) bonded thereto, the pipe (10) being made of water-impervious material and having foamed closed-cells therein. The drip irrigation pipe (10) may be used in a piping package comprising also a spool. The length of the pipe (10) and the number of the emitter units (12) in the package are greater than those which the package of the same weight with the same spool would have, if the pipe (10) was made of the same material but not foamed, and had the same outer diameter and about the same thickness.
Abstract:
A delivery system and method for interstitial radiation therapy uses a seed strand composed of a plurality of tubular shaped, hollow radioactive seeds with a bore. The seed strand as assembled with a material provided in the bore and between the spaced seeds is axially stiff and radially flexible and is bioabsorbable in living tissue.
