Abstract: A lift mechanism. The lift mechanism includes a base configured to support the lift mechanism in an upright position. A neck is upstanding from the base. A lift bracket is coupled to the neck. A coupling bracket includes a U-shape having a base and arms extending from opposing ends of the base. The base is coupled to the lift bracket. A linear actuator is configured to move the lift bracket up and down along the neck.

Abstract: A solid mercury-releasing material and a method of dispensing precise amounts of mercury into the light emitting chamber of a discharge lamp without introducing the other dispenser components into the chamber are disclosed. The solid material includes an amalgam of one or more metals and mercury in the form of particles of high purity, uniform size and uniform composition.

Abstract: A fluorescent lamp containing zinc amalgam and a method of precisely controlling the amount of mercury introduced into a temperature controlled fluorescent lamp. Precise quantities of mercury may be introduced into a fluorescent lamp in the form of solid zinc amalgam pellets that are in a metastable, non-equilibrium state.

Abstract: A method and apparatus for separating the spheres from the non-spheres in a large number of particles of lamp fill material of substantially equal mass in which the spheres are placed in the grooves of an inclined surface to roll downwardly thereon under the influence of gravity. The grooves are configured to limit the contact with the particles to two points intermediate the depth of the groove so as to keep the particles out of contact with the bottom of the groove. Vacuum pick-up means are used to remove those particles which do not roll down the grooves because of their spherical irregularities. The surfaces in contact with the lamp fill material are made of stainless steel and the entire operation is conducted within the confines of a dry box to minimize contamination.
