low heating value waste ratio to control the flame front and temperature in said incinerator. The flue gas resulting from burning the waste may be used to heat, possibly concentrate partially and/or evaporate (if liquid is present) the fluid waste prior to dispersing it into the flame.
5131192 DUST ARRESTER FOR A SANDING MACHINE Mau-Nan Cheng, ,tuohtmlaK A dust arrester for a sanding machine includes a hollow workbench and a tubular filter unit which is axially rotatable inside the hollow workbench. A suction unit draws polluted air into the workbench to be filtered by the filter unit. A blowing unit is disposed inside the filter unit and generates a downwardly oriented air stream to blow dust particles collected by the filter unit into a removable dust receiving bin inside the workbench. The dust arrester is simple in construction, has a relatively low cost, and can effectively control air pollution.
5131934 APPARATUS FOR REMOVING HAZARDOUS PARTICULATE AND FIBROUS MATERIALS Manhar A Patel assigned to Union Carbide Chemicals & Plastics Technology Corporation A glove bag assembly comprising a glove bag adapted to be optionally sealed horizontally to create an upper and a lower portion; a valve assembly connected at its inlet to said lower portion via a conduit and at its outlet to a waste container; and vacuum-generating means communicating with splitter valve means, whereby the amount of vacuum applied to the entire assembly can be controlled.
5132227 MONITORING FORMALDEHYDE Thomas J Kelly assigned to Batelle Memorial Institute Methods and apparatus for monitoring formaldehyde vapor in a gas, comprising directing the gas into contact with an aqueous acidic solution
that can dissolve the vapor and thus collect it therein, separating the gas from the solution, reacting the solution with a reagent to form from the collected formaldehyde a derivative that can be excited by radiation at a wavelength in the range of about 230 to 300 (typically 254) nanometers to fluoresce at a substantially different wavelength, irradiating the solution at a wavelength in said range for excitation, and measuring the intensity of the resulting fluorescence. Typically the fluorescence is measured at a wavelength in the range of about 450 to 550 nanometers and the irradiation and the measurement of fluorescence are carried out by means comprising conventional fluorometric means.
5132663 VEHICLE SAFETY SYSTEM AND METHOD FOR MONITORING TOXIC AND COMBUSTIBLE FUELS Wolfgan Strobl, Klaus Pehr, Eichst Federal Republic Of Germana assigned to Bayerische Motoren Werke Aktiengesellschaft A vehicle and method for detecting the formation of ignitable mixtures in the closed spaces of the vehicle has at least one signal-generating sensor mounted in the closed spaces of the vehicle at a point at which, because of the physical characteristics of the fuel and because of the spatial conditions, harmful substances and/or gases collect first. The signals generated by the at least one sensor are processed in an electronic circuit which, as a function of the measured harmful-substance or gas concentration, actuated movable vehicle parts for closing and opening certain vehicle spaces.
5133089 WATER CLOSET FLUSHING APPARATUS Osamu Tsutsui, Atsuo Makita, Hirofum Takeuchi, Shinji Shibata, N o b o r u Shinbara, Chigasaki, Japan assigned to Toto Ltd In a water closet flushing apparatus of the type in which the flushing water from a flushing water supply source is fed through different flushing water feed lines to a bowl portion and a trap discharge passage defined adjacent to the bottom portion of the bowl portion, a water jet injector is
New Patents provided so as to inject the flushing water jet toward the trap discharge passage, an openingclosing valve is disposed in each of different feed lines, and the operation of the opening-closing valve is controlled by a control unit. The flushing water is flushed into the bowl portion so as to clean the same while the jet of flushing water is injected into the trap discharge passage to cause the same to act as a siphon, whereby waste matter is discharged.

Mobile apparatus is described for melting accumulated ice from surfaces such as aircraft, spacecraft, rocket assemblies, etc. The apparatus includes a heating source for heating air, a compressor, an elongated boom with a discharge head for discharging heated air, and controls for controlling the position of the boom. The apparatus avoids the need for chemicals and accordingly reduces pollution problems.

NEUTRALIZER FOR TOXIC AND NUCLEAR WASTE Gary N Poovey
METHOD OF CONTROLLING COLEOPTERAN INSECTS WITH BACILLUS THURINGIENSIS
A method and apparatus are disclosed wherein toxic and nuclear waste are pumped in a metered fashion or introduced through a sealing door into a plasma region. The plasma region is generated in a sealed chamber by a radio frequency plasma torch. In the plasma region the toxic waste is atomized and ionized. The recombining of the atomized and ionized molecules is managed in the sealed reaction chamber to yield environmentally neutral products. Encapsulation material that is either introduced into the process chamber with the waste or is resident in the process chamber encapsulates radioactive or heavy metal atoms in a glassy stone like material. This encapsulating renders the atoms environmentally neutral. The flow of material in and out of the reaction chamber are regulated carefully. The radio frequency power level is also carefully controlled. These controls insure the neutrality of the recombining products. The fluids exiting the chamber are filtered before release, to insure environmental neutrality.

Kevin W Druding, William Merkle An apparatus for transmitting infections medical waste to a sewer without personnel exposure employing a closed container having a waste tube and a suction tube extending thereinto. The waste is transmitted from an endoscope or other source into the container and the container is drained to a sewer under control of a vacuum applied to the inside of the container. The automated container drainage affords virtually unlimited container volume for improved cleaning of instrument internal channels.

A novel B.t. toxin gene encoding a protein toxic to coleopteran insects has been cloned from a novel coleopteran-active B. thuringiensis microbe. The DNA encoding the B.t. toxin can be used to transform various prokaryotic and eukaryotic microbes to express the B.t. toxin. These recombinant microbes can be used to control coleopteran insects in various environments.
