Title: Manufacture of carbon black
IPC: B65B3/22
Filed: 1964-02-28
Abstract: <PICT:1014379/C1/1> In the process for producing carbon black by the thermal decomposition of injected make hydrocarbons by heat absorbed from a spiralling body of hot combustion gases, the spiralling motion is induced through one or more burner chambers arranged radially round the cylindrical furnace, the gases passing in a spiralling motion in the radial chambers before injection into the furnace. The stream of gas, which may comprise an oxidizing gas and a fluid or gaseous fuel, is caused to spiral in the burner chambers; the spiral is so arranged that the gas stream is emitted along the walls of the furnace in a direction such as to induce a rotating peripheral gas wall.  The make hydro-carbon may be highly aromatic, with a M.W. of 100-400 and a UOP characterization factor of 9 to 10.5.  It may be axially injected into the furnace chamber in the form of an expanding conical spray.  Fig. 3 represents a vertical furnace chamber 18 lined with refractory 19. <PICT:1014379/C1/2> Twelve burner chamber assemblies are uniformly placed round the lower end of the chamber (Fig. 4).  The fluid fuel is charged into the fuel conduits 9 through the bustle pipes 28.  Air is tangentially supplied to chamber 7 at 8 via bustle pipes 31.  The fuel nozzle 10 is retractable and may be positioned anywhere in chamber 7 but preferably in the expanding conical exit 13.  The combustion gases then spiral round the chamber walls and contact the spray of make hydrocarbon applied through nozzle 34.

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B17/42
Filed: 1952-04-04
Abstract: 701,563. Photographic roll-film cameras. KODAK, Ltd. April 4, 1952 [April 4, 1951], No. 8625/52. Class 98(1) Interlocking mechanism between a film winding member and a shutter release member of the camera comprises a slide movable in the camera between two extreme positions and spring-biased towards an intermediate position, means rotatable with the film-winding member for operating the slide which is provided with an element for tensioning shutter mechanism upon movement of the slide in one direction by operation of the film-winding member, a releasable latch co-operating with the slide-operating means for restraining movement of the slide when a recess therein is positioned to permit exposure movement of a shutter releasing member, and an element which effects release of the latch on a release operation of the shutter, whereupon the slide may be moved to a position at which it obstructs the next operation of the shutter releasing member until the slide is again moved by the film-winding member to bring the slide recess into registry with the shutter releasing member. As shown in Figs. 7 and 8, a film-winding knob 10 is fast with a shaft 11, carrying a film spool (not shown) and journaled on a mechanism plate 46 fixed below the top wall 9. A pawl 63 is spring- pressed against a ratchet 57 on shaft 11 so that the knob cannot normally be turned clockwise. When the camera has been loaded, however, the pawl is rocked back by means of an extension 67 protruding outside the camera. Knob 10 is then turned clockwise to move the film across the film gate o a chamber in which it is loosely coiled. From this chamber it is wound back one frame at a time by anticlockwise movement 'of knob 10. During this movement one of a'pair of pins 56 on ratchet 57 engages a finger 55 of a plate 45, slidable on plate 46 and having slots engaging pins 47, 48 on plate 46. Plate 45 is thus moved to the left, a lug 76 thereon engaging a setting element 77 of the shutter, which is of the kind described in Specification 689,376. The plate 45 then returns by action of a spring 52 on a pin 51 on the plate, so that when a pin 56 again presses finger 55, a shoulder 58 on the plate is held by a lug 59 on a lever 60. This indicates that one frame of the film has been wound. A flange 71 of the shutter release 12 is in registry wtih a cut-out portion 10 of the plate, so that it may be operated. The shutter operation rocks a lever 82 which is connected to lever 60 and thus frees lug 59 from shoulder 58, so that plate 45 moves to the left until pins 47, 51 are in line with a stud 54 supporting spring 52. Recess 10 is then out of registry with flange 71, so that the shutter release cannot be operated. Lever 82 also rocks a red filter 78 into the optical path of the viewfinder. The mechanism'includes an exposure counter of the kind described in Specification 701,564.
