Title: Microwave separation of bituminous material from tar sands
Inventor: PIERRE E PHILIPPE
IPC: C10G1/00
Filed: 1988-07-08
Granted: 1992-01-07
Abstract: ABSTRACT A new process has been developed to separate the bituminous fraction from tar sand (oil sand) using selected microwave frequencies.  Frequencies which are preferentially absorbed by water have been found to effect separation.  General heating of tar sands by microwaves, which are not strongly absorbed by water does not produce any apparent separation.  Especially preferred are microwaves of frequency 947, 950 and 953 MHz, which produce fairly clean separation into asphaltic and mineral fractions.  1500 MHz has also been found to be an operable frequency although less preferred.

Abstract: ABSTRACT            DISPLAY SYSTEM COMPRISING A WINDOWING MECHANISM     In a display system having a palette 38 for chrominance and/or luminance information, a display buffer 36 for information defining the pixels of a display field, including index values for indexing the palette to select the chrominance and/or luminance of the pixels, a windowing mechanism is provided for associating a different range of index values with each of a plurality of windows and for responding to index values stored at individual pixel positions in the display buffer to determine the visible extent of a given window within the display field.  This allows a plurality of windows to be displayed with a minimum of extra logic and without unduly constraining the choice of colours available within those windows.      In the described embodiment, windows are defined in a first phase by storing index values from the range of values associated with that window at all pixel positions for that window.  Then, in a second phase, the output of a range comparator 46 for comparing index values stored in the display buffer to the range of values associated with a given window is used to control multiplexer means 60 to cause an item of update information destined for a particular pixel position to be stored at that pixel position in the display buffer only if the compa-rison is positive.

Abstract: ABSTRACT A  circuit  for  the  non-linear  limiting  of  the metallic    current    flowing    in   telephone   line conductors.    The  circuit senses the metallic current flowing  in  the conductors.  If that current exceeds a predetermined   limit,  the  circuit  provides  from  a controlled   and  variable  voltage  source  a  voltage across  the  conductors whose amplitude is reduced from the  essentially  constant  amplitude  voltage provided across  the conductors when the current does not exceed the  limit.    The  reduction  in  voltage amplitude is sufficient  to  maintain  the  metallic  current at the limit.
