Abstract: A process for the selective non-destructive hydrogenation of a liquid hydrocarbon feed containing olefines and diolefines comprises passing said feed substantially in the liquid phase through a hydrogenation zone in contact with a porous solid hydrogenation catalyst having a hydrogenation activity index of at least 40 or having a benzene conversion index of at least 50 and having in either case a polymerization activity index less than 35, with a hydrogen charge of 500 to 5,000 standard cubic feet per barrel of feed at a hydrogen inlet pressure of 200 to 1,000 lbs. per square inch, with a liquid hourly space velocity of 0.2 to 15.0 volumes of feed per volume of catalyst, the foregoing conditions and the average reaction temperature being correlated to obtain a mixed phase hydrogenation effluent from said hydrogenation zone in which diolefines have been at least partially saturated; vaporizing a predetermined portion of the liquid phase of said hydrogenation effluent; passing a gaseous material derived from said vaporizing through a subsequent conversion zone in contact with a porous solid conversion catalyst having a desulphurization activity index of at least 80, at a substantially higher average temperature than in said hydrogenation zone, with a total hydrogen charge of 500 to 10,000 standard cubic feet per barrel of feed at a hydrogen partial pressure of 200 to 800 lbs. per square inch, with a liquid hourly space velocity of 0.2 to 6.0 volumes of feed per volume of catalyst to produce a substantially desulphurized conversion effluent having a substantially lower bromine number than said liquid feed.  The hydrogenation zone preferably operates at a temperature below 200 DEG  F. and the conversion zone at an inlet temperature of 350 DEG  to 700 DEG  F. The feed stock may be a pyrolysis gasoline boiling below 400 DEG F., preferably between 90 DEG  and 240 DEG F., containing olefines and diolefines.  The hydrogenation catalyst may be platinum, rhodium or palladium on alumina; nickel; or copper chromite.  The nickel may be supported on kieselguhr, and palladium on activated carbon is also referred to. The catalyst for the conversion stage may be tungsten disulphide, nickel sulphide, nickel-tungsten sulphide or chromia on alumina promoted by molybdena. Oxides or sulphides of cobalt and molybdenum supported on gamma alumina are also referred to.  There is preferably added to the gaseous phase formed from vaporization of the effluent from the hydrogenation zone a substantial amount of a liquid non-volatile flux which may be any liquid substance which is more volatile at any temperature attained by it in the process and is miscible with and unreactive with the liquid feed.  This flux may be the least volatile portion of the liquid effluent from the hydrogenation stage.

The fixed tracks 24 which are for back wheels 20 of the trolleys are set wider apart than the movable tracks 22. The latter, which are for the front wheels 18 of the trolleys, are moved into position either below the fixed tracks 24 for up travelling trolleys 10 or above the tracks 24 for down travelling trolleys 16. This movement is effected by means of a motor driven screw 30 carrying a travelling nut 32 which causes horizontal actuation of a roller mounted framework carrying the tracks 22. The endless drive chain 36 with its reversible drive motor 34 is also mounted on the aforementioned framework and incorporates at spaced intervals, carriages containing the dogs 40, 42, which engage cross members on the trolleys. Transverse projecting stubs on the carriages run in channel members carried by the movable tracks 22.

Roller shutter blinds 46, 48 at the upper and lower ends of the elevator, bridge gaps in the floor which exist at one or other of the ends of the elevator according to the adjustment of the elevator. The endless chain 36 may be made of reinforced rubber and the chain sprockets and dogs 40, 42 may be covered in a non-metallic material. A safety trip device may be incorporated at the top and bottom of the elevator. Several of these elevators may be operated together and may be associated with personal escalators.

The recrystallized region 24 may be of the same or opposite conductivity type to the body 10, and may also allegedly be intrinsic. Semiconductor materials referred to are Si, Ge, SiC, GaAs and other III-V compounds, and II-VI compounds, and suitable metals are Al, Ga, In, Sn/Sb alloy, Sn, Pb, Au or Pt. After cooling to solidify the metal layer 22 a further annealing step is preferably performed to relieve strain around the layer 22. For a (111) oriented body 10 the layer 22 migrates as a triangular (111) platelet with boundaries in (112) planes. For a (100) oriented body 10 the migrating droplet takes a pyramidal form with four leading (111) faces and a trailing (100) face. Other possible orientations are described, including some in which the originally deposited metal is a wire oriented along a particular crystal axis.

Abstract: 1,261,479. Measuring acceleration electrically. K. HAKEN. Oct. 5, 1970 [Oct. 7, 1969], No.47211/70. Heading G1N. Means are provided to determine how the acceleration of a body 1 is modified due to gravity when it moves at an indination and to the horizontal. As shown in Fig. 1 a test or proof moss 2 having a value m is provided and Piezo electric elements 3, 4 sense the inertial forces along and perpendicular to the direction of travel. If G is the gravitational force on the moss then the element 4 measures that component of this K 2  which is perpendicular to the direction of travel and by the relation S = #G<SP>2</SP> -K 2 <SP>2</SP> a value for the gravitational conponent S along the direction may be found. Hence if K, is the measured value of force along the direction then by the subtraction K 1  -S a value for the applied force mb may be found and hence b. Fig. 2 shows two alternative arrangements indicated by full and dotted positions of switches 19, 20. In the full position signals K and K 2  are obtained, and K 2  is passed to a squarer circuit 9. The output is subtracted from a signal representative of G<SP>2</SP> in a circuit 10, and the resultant passed to a square root circuit 15 providing an output S. This signal or the negative signal -S is fed to a summing network 12 from which a value of mb may be obtained. A value b/g may be derived at a terminal 17. The alternative arrangement (dotted position of switches) utilizes one moss and three sensors. In a modified arrangement, Fig. 3 (not shown) a single force sensor 27 is utilized, this being attached to a pivoted arm which carries a moss 30 at its lower end. The angle of displacement x depends on both the inclination and the acceleration. Rotation influences a resolver giving values of sin x and cos x and a circuit is disclosed Fig. 4 (not shown) by which appropriate calculations are performed. A circuit involving only the derivation of sin x is also disclosed, Fig. 5 (not shown).

(f) Ti values may then be removed by known method from the resultant aqueous solution. Starting with an Hf: (Hf + Zr) molar ratio of 20%, a final ratio of 99-99.5% may result. (g) The Hf in the enriched aqueous solution may then be precipitated as HfO2.  The acid may be a mineral acid, e.g. HNO3, HCl, H2SO4. Before the acid is added in step (a) the initial aqueous solution may contain 4-60 g. ZrO2, 1-20 g. HfO2, and the following impurities: Si, Fe, Ca, Mg, Al, P, Ti and Na values.

Tributyl phosphate may be used diluted with petroleum hydrocarbons; at least 1-5 volumes tributyl phosphate are used per volume of solution to be heated.  Zirconium values may be recovered from the Hf-depleted organic solution from stage (c) by counter-current contact with demineralized water which extract Zr. Specification 800,426 is referred to.
