    • Provided is a process for efficiently producing laurolactam by simple steps from cyclododecanone and hydroxylamine. This production process comprises the steps of: (a) reacting cyclododecanone with hydroxylamine in an aqueous solution in the presence of an oxime-formation solvent to produce cyclododecanone oxime; (b) separating the reaction mixture obtained after the oxime-forming step into an oil and an aqueous phases and collecting a solution of cyclododecanone oxime of the oil phase; (c) removing a part or all of the oxime-formation solvent and dissolved water from the solution of cyclododecanone oxime which is collected as an oil phase in the oil/aqueous phase separation step, whereby preparing a solution containing a rearrangement solvent to be used in a rearrangement reaction in a later step and the cyclododecanone oxime; (d) producing laurolactam from cyclododecanone oxime by rearrangement reaction using an aromatic-ring containing compound as a rearrangement catalyst; and (e) separating and removing the rearrangement solvent and the rearrangement catalyst from the reaction mixture after the rearrangement step, and purifying the laurolactam.

    • The combination of a spool having a core with a central axis, a supply of flexible line with a plurality of turns wrapped over the core around the central axis, and a control strip having a body which in an operative state on the core extends around the core over the supply of flexible line to prevent the flexible line from inadvertently unwrapping. The core is movable relative to the control strip around the central axis. A gripping portion on the control strip is graspable to hold the control strip substantially stationary while rotating the core around the core axis. An opening is provided through the control strip, with the flexible line extending from one of the turns of the flexible line through the control strip opening to a useable portion of the flexible line that projects outwardly from the control strip. The control strip opening is located so that with the user simultaneously grasping the gripping portion of the control strip and the useable portion of the flexible line and exerting oppositely directed forces thereon in a first line, the useable portion of the flexible line projects from the one turn in a second line that is substantially tangent to the one turn and parallel to the first line.
