Title: Improvements in or relating to catalysts for the synthesis of hydrocarbons
IPC: B01J23/843
Filed: 1947-09-19
Abstract: A composite catalyst of iron oxide and an alkali metal pyroantimonate (see Group III), is used to synthesize hydrocarbons from a one to one hydrogen carbon monoxide mixture at a feed rate of 200 volumes per hour a temperature between 450 DEG  and 675 DEG  F. and a pressure between 120 and 500 pounds per square inch gauge.ALSO:A Fischer-Tropsch synthesis catalyst is prepared by heating a mixture of a major proportion of iron oxide and a minor proportion of an alkali metal pyroantimonate in a free oxygen containing atmosphere, then reducing at elevated temperature. The oxidation temperature is 1000 DEG  F. and the reduction temperature 500-700 DEG  F.  The iron oxide is the alpha, gamma or ferro-ferric oxide.  80 per cent to 99.8 per cent by weight of oxide are used, the remainder being pyroantimonate.  Ferro-ferric oxide and potassium pyroantimonate are mixed and slurried with alcohol.  The paste is dried and ground to pass a 30-mesh screen and formed into pills which can be used in fixed bed or fluidized operation when ground to powder.  The pills are heated in a free oxygen containing atmosphere at 1000 DEG  F. for 4 1/2 hours, cooled and reduced at 700 DEG  F. with hydrogen or 500 DEG  F. with carbon monoxide.  Potassium pyroantimonate is prepared by fuzing caustic potash, adding antimony pentoxide gradually thereto, heating and then cooling; water added, agitated, filtered; molten caustic potash added to the residue whilst filtrate set aside; operations repeated and the two filtrates combined, evaporated at reduced pressure until onset of crystallization, when mother liquor was filtered off; crystals purified by washing with alcohol until free from alkali, and then dried, prior to incorporation with the iron oxide.

Abstract: 518,653. Roll-film cameras. NATIONAL SCREEN SERVICE, Ltd., HEPWORTH, C. M., and KIMBERLEY, P. Sept. 1, 1938, No. 25633. [Class 98 (i)] A film feed mechanism for a camera using marginally-perforated films comprises a slide 9 movable against a slight frictional resistance parallel to the focal plane and a bell-crank lever 14 pivoted on the slide so as to rock about all axis parallel to the focal plane and transverse to the path of the slide, one arm of the lever being formed by film-feeding claws 15 which are brought into and out of engagement with the perforations as the lever is rocked, and the other arm 16 being connected to a manuallyoperable draw-cord 17 or the like and to a restoring spring 20. The pull on the cord 17 first, owing to the frictional resistance to the movement of the slide, rocks the lever so that the claws 15 engage the film perforations, and then moves the slide to make the feed stroke. On releasing the cord, the spring 20 first rocks the lever to disengage the claws, and then returns the slide., The necessary resistance to the movement of the slide may be provided by a spring 26 engaging a fibre strip on it. The film is brought into correct registration when it is inserted by a pin 27 which engages one of the perforations and is carried by a spring which is engaged by a rotatable cam 28 to withdraw the pin. The take-up spool 4 may be operated by an external pulley on the spindle which is rotated by a cord coupled to the draw cord 17.

Filed: 1944-12-21
Abstract: 609,715. Automatic pressure control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. Dec. 21, 1944, No. 25653. Convention date, Feb. 22, 1943. [Class 38 (iv)] The turbine driving a compressor feeding air to an internal-combustion engine is controlled in dependence on the acceleration of the turbine and the pressure of the air delivered. In the form shown, the proportion of the air from exhaust manifold 25 of engine 10 fed to the turbine 27 driving compressor 12 depends on gate 31 adjusted through gear 38 by motor 36 having its field windings 40, 41 controlled by a bridge network containing four variable resistances 73, 76, 78 and 87, the first being manually controlled. Arm 80 of resistance 78 is controlled by the pressure of the air fed from compressor 12 through cooler 14 to the carburetter 16 while arm 75 on resistance 76 varies with rate of change of pressure at the exhaust manifold 25, since the bellows 106 is connected thereto through a needle valve while rheostat 87 readjusts the bridge when the gate 31 is moved. In a modification, the rheostat is omitted and the bellows controlling the slider thereof are replaced by a switch which short-circuits part of resistance 78 and thereby slows down the turbine when the speed or acceleration of the latter exceeds a predetermined value. Specifications 605,449 and 605,450 are referred to.

Abstract: 913,755. Measuring electrically. NEW YORK AIR BRAKE CO. July 25, 1960, No. 25808/60. Class 40 (1). [Also in Group XIX] Indicating apparatus controlled by impulses from a remote location comprises a pointer 132 positioned back and forth by a member 90 which is driven in opposite directions between two stops by separate driving arms 70, 80, either of which can be connected or disconnected from a common constant speed driving motor 120. The motor 120 drives two discs with peripheral teeth 57, 55, at the same speed but in opposite directions about the axis of a shaft 50, to which is fixed a plate 68 with a forked extension engaging a fixed spacer to prevent the shaft 50 rotating. The shaft 50 is slidable in an axial direction and when urged to the right by a spring 110, as shown in Fig. 3, the plate 68 sandwiches two wheels 74 on the arm 70 between itself and the disc with teeth 57 so that this disc drives the arm 70 from one stop into contact with the member 90 which it pushes towards the other stop. When a solenoid 100 is energized its armature 102 presses against a stronger spring 112 to overcome the spring 110 and displace the shaft 50 so that the plate 68 releases the arm 70 which is spring-returned to its initial stop and sandwiches two wheels 84 on the arm 80 between itself and the disc with teeth 55 so that this disc drives arm 80 from the second stop toward the opposite side of the member 90 which it pushes towards the first stop. The member 90 is secured to a gear-wheel 92 meshing with a sector 142 on the shaft 140 of the pointer 132. A leaf-spring 94 bearing on a fixed plate 96 acts as a brake to hold the member 90 and pointer 132 in set position. The apparatus is described as the receiver in a telemetering system wherein at the remote station another motor operating in synchronizm with the motor 120 drives a cam co-operating with a measuring instrument to close a circuit, including the solenoid 120 for a part of each cycle proportional to the value of the quantity being measured. In this way the pointer 132 indicates the value of the measured quantity against an appropriate scale.
