Abstract: ABSTRACT OF THE DISCLOSURE     Novel and improved methods and apparatus for processing liquid or viscous materials.  Essentially, the methods and apparatus involve feeding liquid materials to an annular processing passage for controlled processing.          The annular processing passage is provided by two elements.  One is a rotatable element carrying at least one processing channel.  The other element is stationary and provides a complementary coaxial surface arranged with the channel to provide the enclosed processing passage.  Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material from the passage, an element near the outlet providing a material collecting end wall surface and an element positioned between the inlet and outlet providing a liquid material spreading surface.  Rotation of the rotatable element toward the spreading surface provides a coaction between the rotatable element and the spreading surface so that relative movement is established between the rotating inner channel walls and liquid material between the inlet and the spreader surface.  Because of the relative movement, the liquid material is spread toward the walls and dragged by the walls through a clearance between the sides of the spreading surface providing member and the side walls as thin layers providing central spaces of the passage downstream of the spreader surface which are free of liquid material.  Means are arranged for communicating with the free central spaces to add materials to or withdraw materials from the free central space.

Abstract: Process for Dehydration and Demineralization of Diluted Bitumen Abstract of the Disclosure Diluted bitumen emulsion, the aqueous phase of which carries undissolved mineral particles, is upgraded by resolving it by subjecting it to a unidirectional electric field established between an energized electrode and an aqueous material surface serving as an electrical ground. The emulsion is introduced below the level of such surface and allowed to rise. A potential gradient is provided which is sufficient to cause coalescence of the aqueous material in the emulsion as soon as the emulsion breaks the aqueous material surface, the emulsion thereby being resolved at such surface.

Abstract: VEHICLE DIGITAL ANTI-THEFT SYSTEM     Abstract of the Disclosure An anti-theft device for an automotive vehicle or any internal combustion engine turned over by a starter, in which electrical energy is connected to the starter only at such times as several rotatable digital members are arranged in selected positions.  The digital control means may be positioned in either of two alternative coded positions to energize the starter depending upon the position of a hidden switch which the user manipulates according to the particular code he desires.          The digital means are connected to the starter such that an unauthorized "hot wire" creates a short circuit for the thief.  Similarly, the ignition coil is so wired as to provide a short circuit if the thief should attempt to hot wire the ignition coil.

Abstract: ABSTRACT OF THE DISCLOSURE        In mining a heavy coal seam that must be excavated in several benches, the excavation of the uppermost bench is accompanied by the introduction of a cementitious slurry into the resulting stope for consolidating the waste rock present therein, preparatorily to the excavation of the next-lower bench, and proceeding in like manner with the second bench if a third one is to follow. The cementitious slurry comprises burnt or slaked lime, and/or portland cement, suspended in water in a quantity of about 10 to 60 % by weight and preferably together with a small percentage of chlorides of one or more alkali or alkaline--earth metals, to which ceramic aggregates of large specific surface such as mineral ashes, slag, sand or dolomite powder may be added in a quantity of up to about 30 % of the weight of the water. The slurry, on being admitted to the stope in an amount of at least 10 % of the volume thereof, causes the waste rock to swell and to form a solid layer of up to approximately a meter in thickness which allows the next-lower bench to be excavated after only about a month's delay.

Abstract: ABSTRACT OF THE DISCLOSURE       A motor-operated memorandum device comprising a casing with a window, containing a pair of reels on which each end of a lengthy strip of paper is wound, a reversible electric motor, a power transmission changeover mechanism, a pair of reduction gear trains disposed symmetrically one on each side of the electric motor and connected to the reels, and a compact switch mechanism operated by two push buttons for selecting the direction of rotation of the reels by changing the polarity of the circuit to the electric motor.  The power transmission changeover mechanism comprises a pinion fixed to the end of the electric motor shaft, and at least one floating gear, the position of which can be changed by the direction of rotation of the electric motor.  When the electric motor rotates in one direction, the pinion brings a floating gear into meshing contact with the first reduction gear in one of the gear trains, and when the motor rotates in the opposite direction the pinion moves a floating  gear into meshing contact with the second gear train.  Thus, the driving force of the electric motor is transmitted through a floating gear to either of the reduction gear trains and further to one or the other of the reels.  It is also possible to rotate the reels manually by means of a knob fixed to one end of each reel.  The aforesaid casing may be provided at one end thereof with a manually operated indicator of the month, the day of the month, the day of the week, etc.
