A swimming pool skimmer maintenance apparatus () includes an elongate tubular handle () having a hook end () and an opposed sealing end (). The sealing end includes a sealing structure such as a spherical ball () defining a sealing surface effective to seal a skimmer suction port to prevent a flow of water through the skimmer suction port. The hook end supports a metal wire hook () which extends from the handle and which is adapted to lift a debris collection basket, a skimmer diverter or a skimmer lid present at the skimmer. The apparatus is also useful for safely probing the skimmer for animals or insects.

An induction furnace (60) for reflowing a portion of an optical preform (12) in order to draw a lightguide fiber (11) therefrom includes a tubular susceptor (80) which is disposed centrally within a beaker (75) and a sleeve (82) which is disposed concentrically about the susceptor. The sleeve is spaced from the susceptor and is surrounded by insulating grain (83). A high frequency coil (84) is energized to couple its electromagnetic field to the susceptor to heat and reflow a portion of the preform. The movement of contaminating particles of the insulating grain into the interior of the susceptor is prevented substantially by annular, felt-like discs (91, 105) at the bottom and top of the beaker. The discs collect particulates which move downwardly and upwardly and because of their compliant engagement with the beaker and with the sleeve, they provide seals at those interfaces. The discs also are effective to prevent inadvertent lateral movement of the sleeve to maintain the concentricity of the sleeve and the susceptor. The top of the furnace is provided with a cap (93) which is supported by the susceptor that extends into a stepped opening of the cap.
