Title: Improvements in carbon black
IPC: C09C1/50
Filed: 1949-11-08
Abstract: <PICT:0664033/III/1> <PICT:0664033/III/2> In the production of carbon black by the decomposition of a hydrocarbon in a furnace heated by combustion gases, a combustible mixture of fuel gas and air or hot combustion gas is injected tangentially into one end of a furnace chamber which comprises a cylindrical body portion provided at the fuel gas injection end with a coaxial outlet conduit of smaller diameter than the chamber, and tapered at the other to a cone-shaped extension.  A high velocity blast flame is produced which spirals along the furnace wall to the far end of the cone-shaped extension and returns as an inner spiral which is withdrawn from the coaxial outlet conduit.  Hydrocarbon gas or liquid is separately introduced into the furnace so as to form a thin sheet at the boundary surface of the inner and outer spirals where the hydrocarbon is decomposed to form carbon particles which are withdrawn from the furnace through the outlet conduit in suspension in the furnace gas effluent.  In Figs. 1 and 2, fuel gas is supplied from pipe 9 to nipples 11 and air from pipe 8, the resulting flame entering the cylindrical body 1 through burner ports 6 to form an outer spiral which is reflected from the conical portion 2 as an inner spiral, the latter being withdrawn through the tube 12.  Hydrocarbon may be injected either from an adjustable inlet 14, this being preferred for gaseous hydrocarbon, or directly into the boundary surface of the spirals by pipes 16 or 17.  Preferably the height/internal diameter ratio of both the cylindrical and conical portions is between 1 and 2, and the inside diameter of the outlet conduit between 0.3 and 0.7 times the internal diameter of the cylindrical body portion.

Title: Improvements in or relating to labelling machines for applying wrap-around labels
IPC: B65C9/36
Filed: 1956-09-24
Abstract: 809,475. Labelling machines. MEYER MANUFACTURING CO., G. J. Sept. 24, 1956 [June 26, 1956], No. 29125/56. Class 73 In a labelling machine adapted to affix labels whose ends extend more than 270 degrees around a bottle neck, bottles B moved continuously along a conveyer C past a station G where the centres of previously gummed labels are applied to them; they then move past a station L where presser-wipers and rotating brush Wipers situated on opposite sides of the conveyer complete the labelling, the rotating wipers wiping on the two ends of the neck labels successively. The labels are affixed simultaneously to groups of three bottles which are spaced on the conveyer G by a rotating worm 153. Body labels are pressed on at the same time as the neck labels on the lines described in Specification 805,074. At G, picker plates p1, p2 and p3 are gummed by known means 194 and rotate about a shaft 409 to pick up neck and body labels from three magazine plates 400 (Fig. 6, not shown). Each picker separates into two parts 401 and 402 which permit grip fingers 406-408, pivoted on the shaft 409 and having pneumatic suckers 411 and 412; to pass between them and transfer the labels to the bottles B which are meanwhile supported by holders 445b (Fig. 9, not shown) mounted on a shaft parallel to 409. Both the fingers and the holders are made resilient with springs to adapt to the bottle contour and both oscillate along their supporting shafts so as to move alongside the conveyer whilst the labels are applied. The wipers at L are carried on members 338 and 338a having orbital motion transmitted by cranks 336 and 337 on shafts 326 and 327 so as to move alongside the conveyer whilst wiping the bottles. Shafts 422-427 on the member 338a rotate at twice the speed of the shafts 326 and 327 and carry six brush wipers 438, the first three of which rotate in the opposite direction to the second three. Bottle supports with rubber pads mounted on pneumatic rams 34 are situated below the brushes and presser wipers 510 to press on the central parts of the neck and 'body labels are opposite on similar rams 34 on the member 338. The rubber pads at bottle-neck level on the wipers 510 are protected against damage by the brushes by curved metal shields 442 and 443 (Fig. 17, not shown) which also serve to protect the unwiped end of three neck labels at the first wiping station. The mechanically operated components of the labelling apparatus are operated by an electric motor M driving appropriate gearing (Fig. 10, not shown) through a shaft 119.

Title: Method for inflating hollow passageway panels and apparatus for use therewith
IPC: B21D53/04
Filed: 1959-08-27
Abstract: 923,567. Making heat exchanger panels; stamping. REYNOLDS METALS CO. Aug. 27, 1959 [Sept. 11, 1958], No. 29373/59. Classes 83 (2) and 83 (4). A method of forming an inflated article from a flat composite metallic sheet having portions bonded together and inflatable unbonded passageway portions comprises confining said article between relatively movable platens in a press, applying an inflation-resisting pressure to said platens by means of a first pressure fluid prior to inflation of said article and simultaneously reinforcing through mechanical leverage the effect of said first pressure fluid in order to enhance the pressure resistance of said platens on the regions at which said platens normally deflect during inflation of the article, and subsequently supplying an inflating second pressure fluid to said article while simultaneously maintaining said pressure resistance reinforcement upon said platens, said second fluid being under a higher pressure than said first fluid. The press includes a framework having spaced pairs of base-plates 22, 23 located by tie-rods 32, 33 and spacer tubes. The stationary lower platen 37 of the press is supported on base beams 36, the outer ends of which also support pairs of vertical members 39, 40 at the upper end of which are mounted shafts 45, 48 respectively carrying press leverage arms 74. Completing the framework and giving additional rigidity thereto are horizontal tie plates 52, 53. Housed within the framework is a movable upper floating platen 57. Since a distribution of pressure is desired at different areas inboard of the edges of the platens the several pressure arms 74 are constructed for different effective leverages although the length of each arm and the pressure exerted by their individual fluidpressure double-acting cylinders 66, 67 are the same. This difference in leverage is effected by the location of pressure-applying pads 87 on each pressure arm. The lower stationary platen is supported on pads 88 located immediately below the pressure pads 87, so that both platens receive clamping pressure in these areas which are indicated A to J in Fig. 4. The platens are provided with cushioning springs 117, 118. Bottoming blocks 120, 121 are provided along the side edges of the lower platen to locate and support the upper platen before prestressing according to the invention. The fluid pressure system for inflating the panel may be separate from or combined with the fluid pressure system for operating the press.

Title: Electromagnetic fluid valve
IPC: G21C7/16
Filed: 1969-06-13
Abstract: 1,222,634. Fluidic switches; controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 13 June, 1969 [24 July, 1968], No. 30140/69. Headings G4P and G6C. Electrically conductive fluid, e.g. molten sodium reactor coolant, passes from inlet duct 34, Fig. 3, to outlet duct 35 or 36 of a fluidic switch under the control of fluid in control duet 39 which may be supplied as shown from a point upstream of the inlet duct jet. When electromagnetic means 30 is energized flow in control duct 39 is prevented, and fluid passes to duct 36, as shown, owing to the wall attachment effect. When the means is de-energized, fluid flows from the control duct and deflects the jet so that it passes to duct 35, Fig. 2 (not shown). As applied to control of the position of a control rod and piston assembly 13 in a cylinder 12 in a sodium cooled reactor, Fig. 1, the switch 29 normally directs a jet of coolant tapped from the main coolant flow path 22, 24 to duct 32, thereby raising assembly 13. If the electromagnetic control means 30 acting on the fluid in the switch is de-energized or fails, the jet automatically switches to duct 31 allowing assembly 13 to fall to its lowest position.
