Abstract: "SYSTEM FOR HANDLING THE UNDERFLOW  FROM A PRIMARY SEPARATION VESSEL IN THE TAR SAND HOT WATER PROCESS"                    ABSTRACT OF THE DISCLOSURE                For operating control and safety, a close-coupled pump is direct connected to the underflow of the primary separation vessel (PSV).  The desired discharge density of the PSV is 70 - 80% solids in order to minimize bitumen losses.  For a good pumping system, the pump discharge density should be less than 65% solids to avoid settling out of the solids in the downstream conduit.  Therefore it is necessary to dilute the PSV underflow before it reaches the pump.           Secondary flotation tailings, a dilute stream containing a high proportion of fine solids, is used for this purpose.           The solids content of the PSV underflow is monitored by one of two alternative systems - a torque recorder on the PSV rake shaft or a density gauge on the PSV underflow conduit.  The former is used when the PSV is being fed low fines tar sand -the latter when it is treating high fines tar sand.  The density of the stream at the pump discharge is monitored to control the amount of secondary flotation tailings added.           By the use of the controlled-speed, close-coupled pump, a closed system for controlling underflow density is provided.           By using secondary tailings as the diluent, water requirements for the process are reduced and a pumpable mixture is provided from which the solids do not readily settle out.

In accordance with the invention there is provided a syringe having a plastic barrel, a tip on the front of the barrel, and a plunger which extends from the rear of the barrel and is manually actuable.  The syringe has volumetric indicia disposed in a longitudinal pattern along its barrel.  A generally cylindrical body of radiation-shielding material covers the barrel of the syringe.  The body has a slot therein which is in registration with at least some of the indicia.  A plastic shell of generally cylindrical shape covers the radiation-shielding body and the shell has a slot which-is-in registration-with the slot in the radiation-shielding body.  A transparent radiation-shielding member, such as a rectangular leaded-glass member, is proportioned to generally conform in size to the slot in the body and is removably insertible therein.  Finally, manually actuable means are provided for retaining the radiation-shielding member in the body.  In one embodiment of the invention the retaining means comprises a retaining sleeve proportioned to slideably fit over the shell and which extends over at least a portion of the periphery  of the radiation-shielding member so as to retain the radiation-shielding member.  In this embodiment the retaining shell has a slot which is in general registration with the parallel edges of the radiation-shielding member, and a pair of lipped panels extend outwardly from the parallel edges of the slot.  The lipped panels are proportioned such that the lips engage the upper edges of the radiation-shielding member so as to retain it in place.  In another embodiment of the invention the radiation-shielding member is removably slideable within the panels of the shell for temporary retention.  Further disclosed is a syringe plunger having a protective shielding plug.

Abstract: ABSTRACT OF THE DISCLOSURE:        A part of the luminance signal spectrum Y approximately less than the chrominance signal spectrum is extracted from the input video signal (Y + S.P.) through a single filtering.   The subtraction of amplitude of a direct predetermined luminance signal K to the amplitude of luminance signal Y puts out a signal (Y-K).  The latter signal is cut out by switching at a reference voltage under the control of a switching signal representing pictures for special effects, and is then subtracted from the video signal (Y + S.P.).  When the switching signal selects the reference voltage, the output video signal is identical to the input video signal (Y + S.P.).         When the switching signal selects signal (Y-K), the output video signal transmits the special effects pictures with predetermined luminance K and a chrominance equal to that cor-responding to the input video signal.
