Abstract: In some embodiments, a method for processing an optical fiber includes: drawing an optical fiber through a draw furnace, conveying the optical fiber through a flame reheating device downstream from the draw furnace, wherein the flame reheating device comprises one or more burners each comprising: a body having a top surface and an opposing bottom surface, an opening within the body extending from the top surface through the body to the bottom surface, wherein the optical fiber passes through the opening, and one or more gas outlets within the body; and igniting a flammable gas provided by the one or more gas outlets to form a flame encircling the optical fiber passing through the opening, wherein the flame heats the optical fiber by at least 100 degrees Celsius at a heating rate exceeding 10,000 degrees Celsius/second.

Abstract: An ice remover for use on a substantially flat surface comprises a container having a substantially planar first outer surface portion, which forms a discrete edge with at least a second outer surface portion of the container, and wherein the container can be filled with a fluid to raise the temperature of the substantially planar first outer surface portion for melting ice on the substantially flat surface. The container may comprise one or more further substantially planar outer surface portions with a discrete edge formed between each portion. At least one of the discrete edges may be fitted with a scraper, which may have a serrated edge, e.g. of moulded acrylic. The container may have a removable cap for filling and emptying the fluid. The container may comprise a substantially tubular handle attached to a portion of the surface on an opposing side of the container from the substantially planar first portion.

Abstract: Cycloalkane base oil, methods of making cycloalkane base oil, and dielectric liquid comprising cycloalkane base oil, the cycloalkane base oil comprising a quantity of isoparaffins and from 50 wt. % to 70 wt. % cycloalkanes having the formula CnH2n wherein n is from 15 to 30, said quantity of isoparaffins being less than 50 wt. % of said cycloalkane base oil.

Abstract: In an integrated lube oil process, a lube oil stock is hydrotreated over a non-noble metal containing hydrotreating catalyst in an HDN/HDS unit to remove sulfur and nitrogen from the lube oil stock and produce an HDN/HDS unit effluent. The effluent comprises hydrodesulfurized, hydrodenitrogenated lube oil stock, hydrogen sulfide and ammonia. The hydrogen sulfide and ammonia are stripped from the hydrodesulfurized, hydrodenitrogenated lube oil stock to form a liquid stream comprising stripped lube oil stock and a first gas stream comprising hydrogen sulfide, ammonia and molecular hydrogen. The stripped lube oil stock is hydrotreated over a noble-metal containing hydrotreating catalyst in an HDW unit to produce an HDW unit effluent comprising a dewaxed lube oil stock. A second gas stream comprising molecular hydrogen is separated from the dewaxed lube oil stock. The first gas stream is combined with the second gas stream to form a third gas stream.

Abstract: A process for saturating aromatics in a lube range hydrocarbon is disclosed. The process can be used to raise the viscosity index of the lube range products. The process is carried out over a noble metal catalyst under mild process conditions. The catalyst is resistant to sulfur and nitrogen compounds.

Abstract: The invention comprises a method for applying a curable resin, such as a photosensitive resin, to a substrate such as a papermaker's dewatering felt. The method comprises the steps of providing a substrate; providing a curable liquid resin; providing a second material different from the curable liquid resin; applying the second material to the substrate to occupy at least some of the voids in the substrate intermediate the first and second surfaces of the substrate; applying the curable resin to the substrate; curing at least some of the resin to provide a resin layer on the substrate; and removing at least some of the second material from the substrate, wherein at least some of the second material is removed from the substrate after applying the curable resin to the substrate.
