Abstract: ABSTRACT       METHOD OF UTILIZATION AND DISPOSAL OF SLUDGE     FROM TAR SANDS HOT WATER EXTRACTION PROCESS      A method of treating bitumen-containing sludges or tailings is disclosed which comprises the steps of mix-ing the sludge or tailings with a secondary carbonaceous fuel, reducing the moisture content of the mixture and introducing the mixture into a fluidized bed combustion furnace for combustion,  The method may be used to pro-cess the middlings and froth treatment tailings from the tar sands hot water extraction process.  The method may also be used to treat the sludges reclaimed from tar sands tailings ponds, or the slurries produced as "pro-duced water" in in situ heavy oil production.  The meth-od is particularly suitable for use in combination with a flooded mine tar sands mining method.

Abstract: ABSTRACT          Pressure sensing diaphragms comprise a cylindrical or spherical crystalline member in which an internal cylindrical or spherical chamber is provided.  In the internally loaded embodiments, a fluid is introduced into the chamber and the pressure exerted by the fluid causes generally tensile stress in the region of the diaphragm generally about the chamber.  In the externally loaded embodiments, the diaphragm is immersed within the fluid and the pressure exerted by the fluid causes generally compressive stress in the region of the diaphragm generally about the chamber.  For each of the embodiments, the stresses arising cause certain mechanical and electrical properties of the crystalline material to change.  The change in these properties is detected by observing the frequency behavior of one or more oscillators whose frequencies of operation are controlled by respective surface acoustic wave devices provided in the regions of elastic deformation.  Many diaphragm arrangements are capable of providing temperature compensated pressure measurements.  Two particularly useful orientations for the temperature compensated embodiments are the SST and ST orientations.

Title: Method and device for remotely identifying tv receivers displaying a given channel by means of an identification signal
Inventor: COMEAU RENE WEST AUGER BLVD AL
IPC: H04N7/16

Abstract: ABSTRACT OF THE DISCLOSURE:           .           A method and a device for identifying television receivers tuned to a certain television channel and displaying the video signal thereof.  The method consists in introducing an identification signal in the television signal of the television channel at its source before its transmission towards the  television receivers.  The nature of the identi-fication signal as well as the way of introducing it in the television signal are both selected so that this identifica-tion signal is irradiated in the air at the television receivers end, when the receivers are tuned to the concerned channel and display the video signal thereof, due to the phenomenom of cathode - ray - tube radiation caused by the presence of high voltages modulated by the luminance informa-tion at the luminance component frequencies. By detecting the identification signal in the proximity of one television receiver, it can be determined that this receiver is tuned to the television channel in question and displays the video signal thereof.  When an identification signal is introduced in the television signal of each television channel, it is possible to remotely determine which channel has its video signal displayed on a specific television receiver by identi-fying the channel corresponding to the identification signal detected in the proximity of such a specific receiver.  Two very interesting applications of the method and device are as follows:  detection of illegal or pirate decoders in a secured television system, such as pay television, and regulating control in areas where television license fees are required by law, such as in France, United Kingdom, Europe, etc..., to differentiate between the use of television receivers with computers or video cassette recorders, and with received broadcast signals.

Abstract: ABSTRACT An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photocon-ductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photo-conductive member.

Abstract: Abstract:            Improved reference pressure devices for calibra-ting pressure-measuring instruments A  differential-pressure  transmitter  having  a range diaphragm and a slack diaphragm to receive process pressures and to apply such pressures to an  interior  sealed  chamber  containing  a  fill-liquid.   A  vertically-oriented  tube  containing liquid communicating with the  instrument  fill-liquid contains a ball movable by gravity down through  the  liquid  to  create  a  reference-pressure pulse directed to the range diaphragm to provide for checking instrument performance. A relatively large weight is suspended from the ball to increase the effect of gravity on the ball,  so  as  to  increase  the magnitude  of the reference-pressure pulse.   A flexible seal-and-pivot connection is provided at the top of the tube to permit substantial inclinations of the instrument  relative  to vertical  without  inter-ference with the wall of the tube.  The addition-al  weight  is  in  one  embodiment  divided  into vertically-separable  segments  to  provide  for successive  bottoming  of  the  segments  as  the weight descends,  to provide a stepped pressure pulse.  Errors due to change in static pressure are avoided or reduced by  special compensating arrangements.
