Abstract: An approach is provided for generating red mercury (II) sulfide from elemental mercury. Elemental mercury is combined with sulfur and heated until vaporized. At least a portion of the elemental mercury reacts with the vaporized sulfur to form the mercury (II) sulfide. Un-reacted elemental mercury is drawn off and condensed by a condenser.

Abstract: An apparatus is provided for generating mercury (II) sulfide from elemental mercury. Elemental mercury is injected into a heated and sealed reaction vessel containing vaporized sulfur. The elemental mercury reacts with at least a portion of the vaporized sulfur to form the mercury (II) sulfide within the reaction vessel. The formed mercury (II) sulfide is then unloaded from the reaction vessel.

Abstract: Packaging for shipping spent fluorescent tubes includes an external paperboard box lined with a plastic bag that encloses a pair of end pads positioned on opposite ends of an array of sleeves. The sleeves form discrete cells in which a spent fluorescent tube can be inserted for shipping. The end pads include foam that is pressed into the ends of the sleeves when the box is shut and confine the tubes to the sleeves in the event of breakage. The foam protects the plastic bag liner by accommodating electrical pins of the lamps and also clamps the lamps in relatively fixed positions while functioning as a shock absorber. The plastic bag is tied closed for shipping so that any mercury which issues from a broken lamp is largely confined to the bag. The packaging better retains mercury for disposition by a recycler, as opposed to release into the environment, and is arranged to serve the convenience of the user for encouraging recycling of fluorescent tubes.

Abstract: A phase locked loop that operates on an input signal received from a disk drive and similar data processing system peripherals, where the input signal has a preamble portion and a data portion. The phase locked loop providing a digital clock signal which is phase locked to the preamble portion. This is accomplished by adjusting the loop response time so that it monotonically decreases in amplitude beginning at a time when the phase locked loop receives the preamble portion and continuing to monotonically decrease during at least a portion of the time that the phase locked loop receives the data portion. The response time may be monotonically decreased in any suitable fashion, such as linearly or exponentially. A specific embodiment of a linearly decreasing signal generator used with a charge pump is disclosed. The results of computer simulations showing a decrease in lock acquisition time and increased noise immunity with shortened preamble time are also discussed.

Abstract: A container for the transport and storage of metallic mercury (Hg). A plastic thimble having a small opening in the upper side wall is disposed in the neck of the container to prevent oxidation of the mercury in the container and to retain mercury that would otherwise leak out due to expansion.
