Sterile gauze dental packs for placement within a tooth extraction site socket to control bleeding by direct pressure. The packs are of various sizes and shapes so as to conform to differing extraction sockets for both adults and children. The sterile gauze prevents infection and the different configurations increase comfort, provides hemostasis by direct pressure, reduce infection risks, and minimize material waste.

A litter screen for use with an animal litter box, for removing solid waste products from the litter box. The litter screen has a hollow body of circular cross-section, open at an upper end and having a perforate screen element at a lower end. A number of curvilinear bars or straight bars form the screen element in the preferred embodiments. The litter screen is lifted from the litter box for removing solid

An electrochemical method of separating heavy metal values from a radioactive molten salt including Li halide at temperatures of about 500 degrees C. The method comprises positioning a solid Li-Cd alloy anode in the molten salt containing the heavy metal values, positioning a Cd-containing cathode or a solid cathode positioned above a catch crucible in the molten salt to recover the heavy metal values, establishing a voltage drop between the anode and the cathode to deposit material at the cathode to reduce the concentration of heavy metals in the salt, and controlling the deposition rate at the cathode by controlling the current between the anode and cathode.
