Isocyanate Derivatizing Agent and Methods of Production and Use

    This invention provides for a novel isocyanate derivatizing agent, 
9-anthracenylmethyl-1-piperazinecarbozylate (PAC), that may be useful 
for the determination of isocyanates in an environmental sample. This 
agent is capable of derivatizing all isocyanate species. A method for 
producing PAC as well as a rapid, sensitive, inexpensive and efficient 
method for measuring the total level of isocyanate in an environmental 
sample are also provided.

U.S. Patent Application SN 60/085,260 (CDC Ref. #: I-005-97/0)

Ore Pass Level and Blockage Locator Device

    This invention comprises of a device that consists of weldable 
strain gauges attached to inexpensive steel strapping that can be 
bolted to the interior of an ore pass. This device provides multiple 
measurement points for the entire length of the ore pass and indicates 
the ore level in the ore pass and the location of any blockages or 
hang-ups. Consequently, this information can reduce accidents 
associated with removing hang-ups by providing an indication of the 
entire length of the ore pass and indicates the ore level in the ore 
pass and the location of any blockages or hang-ups.

Method for Determination of Hexavalent Chromium Using 
Ultrasonication and Storing Anion Exchange Solid Phase Extraction

    A method for the determination of hexavalent chromium in 
environmental and industrial hygiene samples is provided. Based on the 
chemical properties of chromium species in aqueous solutions, a simple, 
fast, sensitive, and economical field method has been developed and 
evaluated for the determination of hexavalent chromium. By means of 
ultrasonic extraction in combination with a strong anion exchange solid 
phase extraction (SAE-SPE) technique, the filtration, preconcentration, 
and isolation of the hexavalent chromium in the presence of other 
chromium species and interferents was achieved. This method can be used 
in both laboratory and field analysis.

Intrinsically-Safe Hazard Alert Module

    This invention relates to an intrinsically-safe roof hazard warning 
device designed to be attached to the roof hazard warning device 
designed to be attached to the roof of a mine to indicate unsupported 
roof or other unsafe conditions. The hazard alert can then direct a 
person's attention to read the warning message on the module, and thus 
avoiding the hazard beyond the device. The device of this invention is 
especially useful in underground mining operations.

U.S. Patent Application SN: 60/083,677 (CDC Ref. #: I-012-98/0)

Method and Apparatus for Detecting a Temperature Increase in an 
Electrical Insulator

    This invention provides a heat-sensitive warning device and a 
related method for visually detecting an increase in the temperature of 
the outer surface of an electrical insulator, which may indicate the 
unsafe flow of leakage of electrical current. Furthermore, the method 
and apparatus of the invention provides visual indicia of a temperature 
increase in the electrical insulator, where this preset temperature is 
well below an unsafe temperature for the particular electrical 
insulator so that the insulator may be replaced prior to reaching the 
unsafe temperature. This invention is particulary useful in underground 
mining operations.

U.S. Patent Application SN: 60/087,131 (CDC Ref. #: I-016-97/0)

Method and Apparatus for Load Rate Monitoring

    This device monitors the dynamic loading rate on support systems 
used in underground mines. The device uses a programmable 
microcontroller to monitor and calculate the loading rates on the 
support system from pressure transducer(s) or weldable strain gage(s) 
instrumentation installed on the support system. Furthermore, this 
invention is programmed to sequentially activate different colored 
lights and audio alarms as the loading rate increases on the support 
system. This information can be used as an aid in determining when to 
install additional support or in determining when to remove equipment 
and/or personnel from the area before a dangerous roof fall occurs.

U.S. Patent Application SN: 60/083,678 (CDC Ref #: I-016-98/0)

Instrumented Cable

    The invention describes a novel way of removing a king wire in a 
cable bolt and molding a new cable bolt king wire with strain gauges on 
it to measure strain in the cable bolt from the loads applied to the 
cable. The disclosed method consists of using a piece of strap metal 
with strain gauges attached to it as the basic wire replacement. This 
assembly is placed in an injector mold and injected with a nonspecified 
forming compound to make the attachment for the new instrumented king 
wire.
