This invention involves a control panel that is removable from a marking machine housing. This removable control panel is used to lower or raise the entire marking machine or just a module or modules of the machine. Wheelchair users have difficult times using a conventional marking machine such as a copier or printer. The user with the removable control panel can lower the entire machine so that access to all components is possible. In addition, the wheelchair user can raise the paper trays to be side by side with the processor module. It is important that the copier raise-lower function be on the control panel in addition to a control for horizontal movement of the module(s). Any other function can be put on the control panel.

This is a system which is adapted to make it easier for a wheelchair occupant to operate a marking system. There is a lowering device that lowers the module or modules to a location convenient to the wheelchair user. The modules ideally are on the same vertical plane or to a low plane selected by the user. Also, there is a horizontally positioning device that can move the modules to any preferable location.

Disclosed is a process for removing contaminants from a contaminated area of the subsurface which comprises providing a borehole in the contaminated area; placing in the borehole a perforated riser pipe inside of which is situated a vacuum extraction pipe with an opening situated within the perforated riser pipe, wherein a packing is situated in a portion of the annular space between the vacuum extraction pipe and the perforated riser pipe; applying a vacuum to the vacuum extraction pipe to draw gases and liquid from the subsurface into the perforated riser pipe below the packing and from the riser pipe into the vacuum extraction pipe and transport both the gases and the liquid to the surface as a common stream; forming from the common stream a stream which is primarily liquid and a stream which is primarily gaseous; and removing contaminants from at least one of the liquid stream and the gaseous stream. Also disclosed is an apparatus for carrying out the disclosed process.

Disclosed is a process and apparatus for removing contaminants from a contaminated area of the ground, the ground having a plurality of paths of preferential flow at different depths, which process comprises providing a borehole in the contaminated area to intersect at least a first path of preferential flow and a second path of preferential flow; placing in the borehole a first vacuum extraction pipe having a bottom opening situated within the first path of preferential flow and a second vacuum extraction pipe having a bottom opening situated within the second path of preferential flow; isolating the first path of preferential flow from the second path of preferential flow so that a vacuum applied to the first vacuum extraction pipe will extract gases and liquids from only the first path of preferential flow, and a vacuum applied to the second vacuum extraction pipe will extract gases and liquids from only the second path of preferential flow; applying a vacuum to at least one of the vacuum extraction pipes to draw gases and liquid from at least one of the paths of preferential flow into a vacuum extraction pipe and transport the gases and liquid to the surface as a common stream; forming from the common stream a stream which is liquid and a stream which is gaseous; and removing contaminants from the liquid and/or gaseous streams.

Apparatus for extracting contaminants from a stream comprising a contaminant-containing mixture of liquids and gases which comprises: (a) a contaminant-containing mixture input; (b) a vapor-liquid separator receiving the contaminant-containing mixture from the input and producing a liquid component stream at a first outlet and a gaseous component at a second outlet; (c) an optional first contaminant removal system receiving the liquid component stream from the vapor-liquid separator and producing a contaminant-free liquid stream; (d) a vacuum inducing device in fluid communication with the contaminant-containing mixture input and the vapor-liquid separator and receiving said gaseous component from the vapor-liquid separator; (e) a cooling element receiving the gaseous component at a first temperature from the vacuum inducing device and producing the gaseous component at a second temperature from a first outlet and a condensed liquid component from a second outlet, said second temperature being lower than said first temperature; (f) a heating element receiving the gaseous component from the cooling element at said second temperature and producing a reduced-relative-humidity gas component at a third temperature, said third temperature being higher than said second temperature, said heating element having a heating jacket surrounding a conduit through which the gaseous component passes through the heating element, said heating jacket receiving a heating fluid from a first heat fluid conduit into a heating jacket input and outputting said heating fluid from a heating jacket outlet into a second heating fluid conduit; and (g) an optional second contaminant removal system receiving the reduced-relative-humidity gas component from the heating element and producing a contaminant-free gas; wherein the apparatus necessarily includes either the first contaminant removal system or the second contaminant removal system.
