Abstract: A mount apparatus, and methods for forming and using the same, are disclosed for at least one coupling optic requiring alignment along an optical transmission axis. A flanged optical assembly tube is provided, within which the coupling optic is placed along an optical transmission axis, the tube having a flange projecting outwardly from its surface. A mount for supporting the tube is provided, having a base section and an upright section perpendicular to the base. The upright section of the mount includes a vertical surface against which at least one surface of the flange of the tube is affixed. Structural and corrective laser welding techniques are disclosed for permanently mounting and aligning the mount apparatus in an optical component package, aligned with other devices. One such optical component disclosed is an optical waveguide amplifier, having a channel waveguide to and from which aligned optical signals are transmitted.

Abstract: An adjustable paper cap is provided as an article of protective head gear particularly adapted for use in food serving and processing facilities as well as in various other types of factories or manufacturing facilities. The cap includes two elongated side panels, one of which has two sections that are telescopically adjustable in a longitudinal direction for accommodating size adjustment. A crown fabricated from a relatively thin and flexible sheet material formed with a multiplicity of pleats to permit substantial lateral expansion and is secured between the side panels. Each side panel is formed with relatively narrow, single-folded, longitudinally extending, upper and lower marginal edge portions which enable the two sections of the one panel to telescopically interfit in securely retained relationship. The crown is attached to the side panels through adhesive bonding of the outermost panel of the pleated crown to a marginal edge portion of the respective side panel.

The crown is attached at each longitudinal side to respective side panels through adhesive bonding of an upwardly directed, outermost panel of the pleated crown to the downwardly directed marginal edge portion of the respective side panel. The crown is only secured to the one side panel section to avoid interference in telescoping of the two side panel sections.
