Title: Innovations by Lennart L Carlson
Introduction
Lennart L Carlson is a notable inventor based in Newport Coast, CA, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in flexible tubing technology, showcasing his innovative approach to engineering solutions.
Latest Patents
Among his latest patents is a flexible tubing with imbedded helical conductors and a method of making it. This invention features a smooth-bore plastic tubing that is resistant to collapse and incorporates multiple electrical conductors outside of the tubing bore, insulated from ambient conditions and from one another. The conductors are designed to have relatively high thermal conductivity to facilitate tidal air flow within the tubing while maintaining high thermal resistance to the surrounding environment. The manufacturing method involves extruding a molten thermoplastic ribbon with a plateau portion that defines grooves for the conductors. The ribbon is then wrapped to form a tube, with conductors embedded in the grooves, and a molten thermoplastic bead applied to create a smooth-bore unitary flexible tubing structure.
Another significant patent is for a double-walled flexible tubing product that includes a helical support bead and a heating conductor. This product features a helically wound support bead between inner and outer walls, with an electrical resistance heating conductor positioned adjacent to the inner wall. This design ensures efficient heat transfer to the fluid flow within the tubing while insulating against heat loss to the ambient environment.
