Title: Gas-solid photocatalytic oxidation of environmental pollutants
Inventor: RAUPP GREGORY B
IPC: C02F1/72
Filed: 1990-09-04
Abstract: Means and methods employing gas-solid heterogenous photocatalysis ("GSHP") to counteract the widespread occurrence of groundwater and air polluted by volatile organic compounds (VOCs) such as trichloroethylene (TCE) and non-volatile organic compounds such as polychlorinated biphenyls (PCBs), and the like without creating other environmentally hostile agents. Common treatment methods such as spray tower aeration and activated carbon adsorption, both of which merely convert pollutants into alternate but equally obnoxious forms, can be augmented by the means and methods hereof to create ecologically innocuous byproducts. Heterogeneous photocatalysis allows the complete destruction of those organic water pollutants normally contained in the effluents of existing water treatment facilities. Ambient temperature ultraviolet-illuminated catalyst, such as titanium dioxide, in the presence of moist air, substantially completely destroys trichloroethylene (TCE) type-materials in a gaseous phase.

Filed: 1991-07-16
Abstract: A  guiding  guard  assembly  for  a  crawler  track vehicle is  relatively  easy  to  install  initially  as  a "retrofit  kit",  and  can also  be  easily  removed  and replaced as needed.  Furthermore,  the  guiding guard does not obstruct idler bearings of the lower run of the track, thus permitting easy servicing.  A plurality of transverse supports   are   secured   to the  vehicle  and  disposed transversely   of   each   crawler   track   and   spaced longitudinally  apart.  Structure  for  locating  a  guiding guard member on each side of each crawler track relative to  the  transverse  supports  is provided so that a lower face of each guiding guard member is spaced closely to a lower  run  of  each  crawler  track  to  resist  excessive twisting of the  track.  Support  portions  secured  to  the transverse  supports  and  guard  portions  secured  to  the guiding  guard  members  have  inclined  locating  surfaces which  cooperate  with  each  other  to  prevent  relative movement between the guiding guard member and the supports when secured together.

Title: Waste disposal process
Inventor: WOLF BERND M
IPC: C10B57/02
Filed: 1990-10-06
Abstract: WASTE DISPOSAL PROCESS    Abstract In a process for the disposal of toxic and/or infectious waste, especially highly halogenated solids, plastic containers, hos-pital waste and the like, to recover useful substances and render inert non-recyclable and unoutgassable residues, outgassing by the pyrolytic process is used, with air excluded and a reduced oxygen content, followed by the direct incineration of the distilla-tion gases obtained from pyrolysis or their cracking to form a pyrolysis separation gas. The waste to be disposed of is inserted in an autoclave (2), partially outgassed there for a period of 20 minutes to 6 hours at about 250 to 320 °C in an initial outgassing stage, then cooled and made into a granulate or pellets measuring from I to 50 mm, which are subsequently treated by the pyroly-sis outgassing method in a second outgassing stage at a temperature of 550 to 600 °C. This generates distillation gas which is sep-arated from the residues, like carbon. ash, heavy metal particles and other components. The liquid partial outgassing intermediate products, like oil and/or coal tars, produced in the autoclave (2) are taken to the second outgassing stage, while the distillation gas separated off in the first outgassing stage in the autoclave (2) is taken off and added to the stream of distillation gas from the second outgassing stage.

Patent CA-2079284-A1 (CA)
Inventor: ATKINSON LOWELL G
IPC: H04N7/173
Filed: 1992-09-28
Abstract: Abstract A two-way cable television (CATV) system includes a cable for transmitting television signals downstream (from a headend to a subscriber) in the VHF frequency band, and for transmitting signals upstream (from the subscriber to the headend) in the frequency band below VHF. A feeder switch is series-connected with the cable through a pair of input/output ports. These ports are normally interconnected by a high pass filter to preclude the transmission of electrical signals in the upstream frequency band. However, circuitry within the feeder switch detects upstream transmission and, in response, replaces the high pass filter with a direct connection between the ports to enable both upstream and downstream transmission. Since each subscriber is connected to the cable via the feeder switch, thermal noise does not accumulate in the upstream direction from subscribers (most of them) who are not presently transmitting.
