Patent MX-9606169-A (MX)
Title: Blade tensioning mechanism.
Inventor: LIGON JAMES MADISON
Filed: 1995-05-30
Abstract: A tensioning member for a blade screen that permits simultaneous tensioning of a plurality of blades in a blade screen, such as for wood chip sorting. The blade screen tensioning member includes a hinged bracket (18) that may be supported on a portion of a frame (100), a spring steel blade holder (14) for engaging a press-snap (42) inserted into a hole in each of the engaged blades (22), and an elastic stop nut (38) and stud (36) for tightening and tensioning the blades (22). The blades (22) are held in place at the opposite end of the frame by a similar holder (12), which however, is fixed rather than hinged. The spring steel blade holder (14) is reinforced for additional strength, and is bent at an approximately 45 degree angle where the press-snap is engaged. The blades themselves may also be provided with a sawtooth detail (600) on a bottom edge to reduce the build-up of wood ribbons or fines that would otherwise occur. A sliding bearing (400) with a dovetail configuration is also provided. This sliding bearing (400) allows a dual-frame blade screen to be assembled, while compensating for any phase angle error between eccenters (418) provided to agitate the wood chips by moving the screens.

Title: Method of decontaminating nuclear waste-containing soil.
Inventor: ABEL ALBERT E
IPC: C22B7/00
Filed: 1995-09-12
Abstract: Soil including sand and clays contaminated with nuclear waste materials, elemental mercury or as mixed waste with hazardous organic compounds are decontaminated by treating with anhydrous liquid ammonia alone or with solvated electrons. Methods comprise concentrating radionuclides, such as plutonium and uranium in the fines of soil and clay to yield residual soil products which are sufficiently free of contaminants to allow reclamation. By concentrating nuclear wastes in soil fines space requirements ordinarily needed for storage of untreated soil and handling costs can be significantly reduced. Ammoniacal liquids, such as anhydrous liquid ammonia facilitates decontamination by breaking up soil into fine slurries for releasing droplets of mercury metal. The high density of the mercury permits precipitation with larger soil particles and for recovery from soil particulates.
