The barber chair with auxiliary seat is configured for use with a client hydraulic salon chair. A hair stylist sits on the barber chair with auxiliary seat. The elevation of the barber chair with auxiliary seat is adjustable. The position of the barber chair with auxiliary seat relative to the client hydraulic salon chair is adjustable. The barber chair with auxiliary seat comprises a client hydraulic salon chair, a stylist hydraulic salon chair, a pedestal, a track system, and a control circuit. The client hydraulic salon chair and the stylist hydraulic salon chair mount on the pedestal. The track system attaches the stylist hydraulic salon chair to the pedestal. The control circuit controls the elevation of the stylist hydraulic salon chair. The control circuit controls the position of the stylist hydraulic salon chair relative to the client hydraulic salon chair.

Reversible crown

A cooling structure ( ) for use inside a ceramic cylindrical tube ( ) of a metal vapor laser ( ) to cool the plasma in the tube ( ), the cooling structure ( ) comprising a plurality of circular metal members ( ) and mounting members ( ) that position the metal members ( ) coaxially in the tube ( ) to form an annular lasing volume, with the metal members ( ) being axially spaced from each other along the length of the tube ( ) to prevent the metal members from shorting out the current flow through the plasma in the tube ( ) and to provide spaces through which the heat from localized hot spots in the plasma may radiate to the other side of the tube ( ).

Large diameter lasing tube cooling arrangement

A high temperature laser assembly capable of withstanding operating temperatures in excess of 1500.degree. C. is described comprising a segmented cylindrical ceramic lasing tube having a plurality of cylindrical ceramic lasing tube segments of the same inner and outer diameters non-rigidly joined together in axial alignment; insulation of uniform thickness surround the walls of the ceramic lasing tube; a ceramic casing, preferably of quartz, surrounding the insulation; and a fluid cooled metal jacket surrounds the ceramic casing. In a preferred embodiment, the inner surface of each of the ceramic lasing tube segments are provided with a pair of oppositely spaced grooves in the wall thereof parallel to the center axis of the segmented cylindrical ceramic lasing tube, and both of the grooves and the center axis of the segmented cylindrical ceramic lasing tube lie in a common plane, with the grooves in each ceramic lasing tube segment in circumferential alignment with the grooves in the adjoining ceramic lasing tube segments; and one or more ceramic plates, all lying in a common plane to one another and with the central axis of the segmented ceramic lasing tube, are received in the grooves to provide additional wall area in the segmented ceramic lasing tube for collision and return to ground state of metastable metal atoms within the segmented ceramic lasing tube.

Segmented lasing tube for high temperature laser assembly

A metal vapor laser is disclosed that recycles condensed metal located at the terminal ends of a plasma tube back toward the center of the tube. A pair of arcuate wedges are incorporated on the bottom of the plasma tube near the terminal ends. The wedges slope downward toward the center so that condensed metal may be transported under the force of gravity away from the terminal ends. The wedges are curved to fit the plasma tube to thereby avoid forming any gaps within the tube interior.

Recirculating wedges for metal-vapor plasma tubes

A mop has an elongated mop head fabricated in sections, with each section being connected by a hinge to the adjoining sections on either side. The outermost sections can be rotated upward independently about their respective hinges so that they lie flat and inverted on the adjacent inner sections, forming a mop with a narrower mop head. The two outer sections thus folded on either side can again be rotated upward about the next hinge to lie flat and inverted on the adjoining inner section, with the outer section nested between the other sections in this folded position. By thus folding the various sections the mop head can be adjusted to a variety of lengths. A locking mechanism at each hinge causes each pair of sections to lock in either the extended or folded positions. The mop handle is attached to the center mop head section by means of a universal-type joint. A removable swab is further provided for the mop head.
