Granted: 2016-10-10
Abstract: Een bekledingskoker (1) voor het omhullen van een onderwater­ leiding, zoals een pijpleiding of een kabelleiding, heeft tenminste één zich rondom in omtreksrichting (C) van de bekledingskoker uitstrekkend perifeer knikgedeelte (4A, 4B, 4C). Dankzij het tenminste ene perifere knikgedeelte kunnen dergelijke bekledingskakers buigingen van de onderwater-leiding goed volgen, ook als de bekledingskakers worden uitgevoerd in hardere en goedkopere materialen dan het zachte, buigzame polyurethaan dat thans meestal wordt toegepast. Er zijn diverse hardere materialen beschikbaar waarmee de bekledingskakers goedkoper vervaardigd kunnen worden, en waarmee onderwater-leidingen goed beschermd worden tegen botsingen. Tevens maakt de toepassing van hardere materialen dat het aantal spanbanden per lengte-eenheid langs onderwater-leidingen kleiner kan zijn dan bij de bekende toepassingen van het zachte polyurethaan. Aldus kan bij een bekledingskoker voorzien van het tenminste ene perifere knikgedeelte aanzienlijk bespaard worden op de kosten van de bekledingskoker en van de daarvoor gebruikte spanbanden.

Title: Polymers and their use in imagable products and image-forming methods
Inventor: KOTTMAIR EDUARD
IPC: B41M5/36
Filed: 2001-05-22
Abstract: Infra-red absorbing polymers useful in imageable products and the lithographic printing field comprise infra-red absorbing groups carried as pendent groups on a polymer backbone. Certain infra-red absorbing groups may also act to insolublize the polymer in a developer, until it is imagewise exposed to infra-red radiation. The resulting heat renders the polymer soluble in the developer. Imagable products employing the infra-red absorbing polymers may include positive working lithographic printing plates.
