Abstract: RECOVERY OF BITUMINOUS OIL FROM TAR SANDS     ABSTRACT     This invention is related to a method of separating the bituminous oil from the solid matters in the oil-bearing sand such as the Athabasca tar sands by subjecting the tar sands in a sub-ultracentrifugal field of sufficient strength and for a sufficient period of time to effect the separation.  The re-covery of oil is promoted by centrifugal sedimentation em-ploying an aqueous alkaline displacement medium having a specific gravity substantially higher than the oil but lower than the sands thereof.

Abstract: SEPARATION OF CHLOROSILANES                          ABSTRACT           An improved method for the separation of close-boiling chlorosilanes is described.  The method consists of the extractive distillation of the close-boiling chlorosilanes using sulfolane as the extractive solvent and thereafter separating the higher-boiling chlorosilane and sulfolane by distilling the higher-boiling chlorosilane from the higher-boiling chlorosilane and sulfolane mixture to which is added a hydrocarbon solvent.  Preferred hydrocarbon solvents include normal-heptane, normal-nonane,  and 2,2,4-trimethyl-pentane.  The sulfolane obtained from the higher-boiling chlorosilane and sulfolane mixture is suitable for recycling to the extractive distillation process as the sulfolane contains only limited amounts of dissolved chlorosilane.

Abstract: ABSTRACT OF THE DISCLOSURE    An image of a moving object with an optically dif-ferentiatable  structure  is  projected  onto  a  grid  of opto-electric  transducers  through a  lens.   The  output signals of at least one square group of four transducers A - D are processed to produce from output signals of the respective transducers a pair of signals I = A + B - C - D and II = B + C - A - D.  The nature of the object is such as to cause periodically varying signals in  the  transducers,  and  there are  thus concerned two signals  shifted  by  a  quarter  period,  from which  the direction  of  movement  can  be determined  by means  of a  logic  circuit.   From  the  frequency  of  the  signals the velocity can be ascertained.  By means of direction dependent counters the path of the object can be deter-mined from the signals.  With a two dimensional matrix of transducers measurements can be effected of movement of the object in different directions.  The measurement is simple and offers versatile possibilities of exploita-tion.

Abstract: Abstract A geodesic dome includes a strut assembly including groups of primary struts having end connectors, each of which has a first hinge loop pinned to a second hinge loop of a successive primary strut end connector so that the end connectors formed closed rigid hubs from which the primary struts outwardly extend.  Interconnection of the primary struts by means of the end connectors forms a plurality of primary triangles.  Each primary triangle is divided into four secondary triangles by means of three secondary struts having their ends connected to the midportions of the three primary struts forming the primary triangle.  Each primary strut and each secondary strut is composed of a pair of glued-together pre-finished wooden beams, the hinge loops of the primary strut end connectors being attached to opposite sides of a plate attached between the wooden beams at each end thereof.  A plurality of straps are also attached between the wooden beams and extend from the outer surfaces of the primary and secondary struts.  Prefabricated triangular panels each composed of an outer plate, a prefinished inner plate and insulation material disposed therebetween are coextensive with the secondary triangles.  The prefabricated panels are positioned against the outer surfaces of the secondary triangles, and the straps are bent around the outer edges of the triangular panels and attached to the outer surface thereof to form a prefinished insulating cover of the geodesic dome.  In one embodiment of the invention, the strut end connectors are used on the ends of upper and lower grid struts of a space frame structure; similar strut end connectors are provided on inter-grid struts and are interconnected with the upper and lower grid strut end connectors to form rigid hubs at which the grid struts and inter-grid struts are interconnected.

A first passage includes a solid valve positioned therein.  Compression of the resilient block causes displacement of the valve and distortion of the block material to break the seal around the valve.          Additional material is provided strategically in this first passage to insure against leaks from system over-pressure.  A second passage includes a capillary to allow continuous low volume flow not controlled by an operator.

Abstract: ABSTRACT A PROCESS FOR THE PREPARATION OF SYNTHETIC HYDROCARBONS        Synthetic hydrocarbons, especially high octane gasoline, are prepared by catalytic conversion in two steps of a synthetis gas containing hydrogen and carbon oxides. In the first step the synthesis gas is converted at 10-80 bar and 200-300°C into an intermediate containing methanol and/or dimethyl ether. Useful catalysts for methanol synthesis are oxides of chromium, aluminium and/or copper, and zinc; and for dimethyl ether synthesis certain zeolites. In the second step the entire intermediate from the first step is converted at the same pressure as in the first step and an inlet temperature of 300-340°C while supplying heat to  obtain an outlet temperature of 410-440°C; the difference between inlet and outlet temperature being at least 30°C higher than the temperature increase caused by the conversion reaction. As catalyst in the second step one can use any conventional catalyst for converting methanol and/or dimethyl ether into hydrocarbons, especially synthetic zeolites. The raw product stream from the second step is cooled and thereby separated into a condensed hydrocarbon product stream and a gaseous recycle stream, the latter being recycled without further separation to the inlet of the first stream and here combined with fresh synthesis gas feed. There is obtained a low rate of deactivation of the catalyst used in the second step and a high quality hydrocarbon product.

Abstract: ABSTRACT        A braking direct current (d.c.)  (ug) is injected by way of a diode into at least one of the motor windings at a make time (T1) which occurs after the tripping of the motor.  The make time  lies between, at the earliest, a first reference time (Tr1) and, at the latest, a second reference time (Tr2), the braking d.c. voltage (ug) being substantially equal to a back-voltage (ur) of the motor winding at the first reference time.  The second reference time leads, by 5% of the full periodicity of the network voltage, the first peak in time of the back voltage to occur after the first reference time.  The polarity of the braking d.c. voltage (ug) at the make time (T1) is opposite to the polarity towards which the back-voltage (ur) is tending at the first reference time.  The braking accuracy of d.c. braked asynchronous motors is improved without increased loading of the motor by relatively heavy currents.
