Patent number: 9613792Abstract: An elongated light source envelope is disclosed. The elongated light source comprises an inner wall and an outer wall formed around a longitudinal axis. The inner wall and the outer wall may be connected at a first axial end by a first side wall and a second axial end by a second side wall. The inner wall, outer wall, the first side wall, and the second side wall define an enclosed space internal to the envelope. The light source envelope further comprises one or more walls formed between the inner wall and the outer wall to further form at least a first enclosed region and a second enclosed region within the enclosed space. The first enclosed region may be configured to emit a different spectrum of ultraviolet radiation from the second enclosed region in response to excitation of the first enclosed region and the second enclosed region by microwave radiation.Type: GrantFiled: March 13, 2014Date of Patent: April 4, 2017Assignees: Heraeus Noblelight America LLC, Consiglio Nazionale Delle RicercheInventors: Andrew David Paul Harbourne, Pradyumna Kumar Swain, Iginio Longo, Carlo Ferrari

Patent number: 7407617Abstract: A method of polymerizing by a free radical polymerization mechanism, product formed thereby, and apparatus for performing this method, are disclosed. The composition to be polymerized by the free radical polymerization mechanism is irradiated by a substantially constant radiation, the radiation being substantially without pulsation. The use of the substantially constant radiation without pulsation reduces premature termination of the polymerization. The substantially constant radiation can be the output of a lamp powered by a constant current, direct current power supply.Type: GrantFiled: January 17, 2006Date of Patent: August 5, 2008Assignee: Fusion UV Systems, Inc.Inventors: Jeffrey K.

Patent number: 4226905Abstract: The present invention provides a process for the manufacture of a polyethylene film having improved tear strength in the transverse direction. The process involves extruding a partially crosslinked polyethylene into film having a thickness between 10 and 100 .mu.m, by a blown film process. The blow-up ratio is in the range of 1.2:1 to 4:1 and the MD draw-down ratio is in the range of 2 to 60. Polyethylenes used in the present invention had prior to being partially crosslinked a density in the range of 0.940 to 0.970 g/cm.sup.3 and a melt index in the range of 0.2 to 15.0 g/10 min. The polyethylene is crosslinked to an extent sufficient to provide a film having an Elmendorf tear strength in the transverse direction substantially less than the tear strength of film made from the uncrosslinked polyethylene. Crosslinking may be accomplished using any known method e.g. by irradiation, through use of crosslinking agents.Type: GrantFiled: April 16, 1979Date of Patent: October 7, 1980Assignee: Du Pont Canada Inc.Inventor: David A.
