IPC: C10G45/46
Filed: 1973-05-14
Abstract: 1412155 Hydrogenation/reforming catalyst INSTITUT FRANCAIS DU PETROLE 14 May 1973 [15 May 1972] 22854/73 Heading B1E [Also in Division C5] A supported hydrocarbon conversion or hydrogenation catalyst is formed by: (i) preparing a homogeneous solution by admixing, at a temperature higher than 100‹C, in a solvent, a salt of a metal of atomic number 22-29, 40-47, 72-79 or 90-92 (or a lewis base coordinate of such a salt) and an inorganic or organometallic reducing agent, the metal component of which is a member of groups Ia, IIa, IIb or IIIb of the periodic table; and, (ii) impregnating a solid carrier with the solution at a temperature above 150‹C. Specified carriers are alumina, silica, titania, zirconia, magnesia and thoria. The carriers should be precalcined for removal of water. The reducing agents specified are alkali metal alkyls, aryls, hydrides, mixed hydrides with boron and aluminium or alkoxyanalates and magnesium, zinc or aluminium trihydrocarbyls. The solvent used in the first step is suitably organic. The Examples describe alumina-impregnated with solutions formed by reacting an alkyl aluminium compound with salts of nickel, cobalt, iron, molybdenum, tungsten, ruthenium, palladium, platinum and silica impregnated with solutions formed by reacting an alkyl aluminium compound with salts of nickel or cobalt.

Title: Improvements in or relating to process for hydrocarbon conversion
IPC: B01J8/04
Filed: 1944-11-17
Abstract: <PICT:0604432/III/1> <PICT:0604432/III/2> The conversion level is maintained constant throughout the body of catalyst in vapour-phase, endothermic hydrocarbon conversion reactions, such as cracking, reforming or dehydrogenation, by injecting into the body of catalyst at a series of points, spaced in the direction of flow, hot inert gas in order to maintain the conversion temperature, the points being so chosen that the volume of catalyst between them increases in the direction of flow in the proportion required to maintain constant the contact time between the hydrocarbon and the catalyst.  In Fig. 1, the hydrocarbon charge enters through line 1, is heated in preheater 2 and is then introduced into chamber 7 which contains catalyst divided into four sections A, B, C, D of increasing depth in the direction of flow.  Hot inert gas from line 5 enters the chamber 7 between the sections of catalyst.  Hot inert gas may also be added to the hydrocarbon immediately before and after it passes through the preheater.  The effluent from chamber 7 is fractionated for the separation of inert gas, products and unconverted material.  The volume increase of catalyst may alternatively be obtained by employing sections of the same depth, but of increasing diameter, as in Fig. 2.  The hot inert gas is preferably steam, but refractory hydrocarbons containing up to 5 carbon atoms per molecule, nitrogen, carbon dioxide, or flue gas may also be used. Catalytic materials mentioned are bauxite, brucite, aluminium silicates, natural and synthetic materials containing zirconia and titania, and synthetic preparations comprising magnesia, alumina and various silica-alumina combinations.  The catalysts may be promoted with minor quantities of metals, metallic salts or metallic oxides, particularly chromium, nickel or zinc oxides.  In an example, gas oil of boiling range 425-700 DEG  F. diluted with 10 per cent by weight of steam was preheated to 985 DEG  F. at 75 lbs. per square inch gauge pressure and passed over 113 cubic feet of bauxite catalyst arranged in four zones, each of 4 foot diameter, but of the following lengths: 0.4, 1.6, 2.9 and 4.1 feet.  The feed rate was one liquid volume of gas oil per volume of catalyst per hour.  The temperature at the end of the first zone was 952 DEG  F. and 17.3 lbs. of steam at 1230 DEG  F. per 90 lbs. of hydrocarbon charge were added to bring the temperature of the mixture to substantially 985 DEG  F.  Similarly, about 17 lbs. of steam at 1230 DEG  F. per every 90 lbs. of gas oil were injected through inlets at the top of the third and fourth sections of the catalyst bed.  The minimum temperature in the catalyst bed was substantially above 950 DEG  F.  The per-pass conversion during a four-hour on-stream period averaged 48 volume per cent of the gas oil charge, with over 92 per cent of the converted material recovered as stabilized end-point gasoline.

Title: Improvements in means for converting rotary motion into reciprocating motion
IPC: F16H37/12
Filed: 1928-08-13
Abstract: 313,431. Miehle Printing Press & Manufacturing Co., (Assignees of Dudley, E. F.). June 11, 1928, [Convention date]. Bed-reciprocating apparatus.-An apparatus for converting rotary into reciprocating motion, which is especially applicable for reciprocating the beds of printing-machines, comprises a single unit of gears adapted to be attached to the frame of the machine as a self-contained unit and to drive the bed at a constant speed during the main portion of its travel and to slow down, reverse, and accelerate the bed at each end of the stroke. As applied to a two revolution cylinder machine, the impression cylinder 2 of the machine is driven by gears 3, 11 from the main driving-shaft 10 which drives the bed-reciprocating unit. This comprises a shaft 21 with a gear wheel or wheels 32 engaging racks 9 on the bed 8, and the shaft 21 is driven alternately in opposite directions during the medial portions of the stroke of the bed by means of sectors 15, 16, on a shaft 18 driven at constant speed by a gear 12 on shaft 10 and a continuous gear 14 on shaft 18. Sector 16 engages a gear 20 on shaft 21 for one third of each rotation of shaft 18, and after an interval of one sixth of a revolution, sector 15 engages a gear 19 on a shaft 24 geared directly to shaft 21, and drives shaft 21 in the reverse direction. During the interval the shaft 21 is reversed by a geared sector 25 which engages a segmental gear 31 on shaft 21. The sector 25 is oscillated by a connecting-rod 28 connected to a crank-pin 30 on an arm fixed to shaft 10. The gears may be enclosed in a casing 52 which may be filled with oil. In a modification, Fig. 8, the motion which is imparted to the oscillating sector for reversing the bed motion is controlled by employing a crank-pin 29, which can be adjusted during the working of the machine, to transmit motion from the connecting. rod 28 to the sector 25. As shown this pin 29 is carried by an eccentric bearing fitted with a lever arm 36 provided with a roller 37 which slides in a cam guide 43 fitted with one or more cusps 45 for rotating the bearing to vary the distance of the pin 29 from the pivot 30, or from the pivot 26 of the sector 25. As shown, the pin 29 is moved at times further from the pivot 26 and thus the extent of movement imparted to the sector 25 is diminished and the speed reduced. When the pin is returned, the speed is accelerated.

Abstract: 1,180,643. Coating. E. S. & A. ROBINSON Ltd. 6 May, 1968 [19 May, 1967], No. 23445/67. Heading B2E. [Also in Division B6] Sheet material having surface projections is printed with a printing medium so that each projection has the printing medium applied to it and the area between the projections also carries printing medium except for those regions immediately surrounding the projections. The material may be a reticulate foraminated sheet, the projections being at the nodes of the network. The surface may be metallised before applying a transparent printing medium. The printing medium can be applied to the sheet by a smooth belt or roller of a hardness selected so that the printing medium is not applied to a region immediately surrounding each projection. In Fig. 1 sheet 1 of plastics material, paper or metal, has projections 2 formed in a regular array by a moulding, embossing or laminating process. The plastics material is translucent and uncoloured and the surface is metallised by a vacuum metallisation process to produce a reflective metal layer 3. The sheet material is then printed by using a smooth belt or roller selected so that the belt when it rides over the projections 2 does not apply printing medium to a region surrounding the projections. The medium is applied to the top of the projections 2 indicated by layer 5, and to the surface in general as a layer 4, and the metallised layer is visible at the unprinted portions 3<SP>1</SP>. In another embodiment (Fig. 3 not shown) a reticulate laminated sheet comprises spokes joining hexagonal nodes. The nodes are thickenings formed by lamination of the spoke-forming strips.
