Abstract: 317,118. Babcock & Wilcox, Ltd., (Babcock & Wilcox Co.). May 10, 1928. Pulverulent-fuel furnaces; walls.-In a steamgenerator furnace in which water tubes, connected in the boiler circulation system, are embedded in one or more walls, damage to the wall due to temperature changes is prevented by making the tubes curved for a part of their length and resiliently supporting them at one or both ends. As shown applied to a pulverulentfuel furnace, the front, back, and side walls enclose water tubes 32, 33, 57 delivering into headers 28 and 43, 29 and 45, and 58 and 60 respectively, while the lower inclined walls 13 leading to the ash outlet 15 enclose further tubes 36 connecting the headers 28, 29 with lower headers 30. The headers 28, 29, 30 are mounted on spring supports 40 carried by girders 41, 42. The tubes 33, 36 are curved adjacent their respective headers 45, 30, while the front wall tubes 32 are bent inwardly to form an ignition arch and then curve outwardly to the header 43. The headers 43, 45 are secured by straps to vertical brackets 48, 49 carried by beams 26, 27, each bracket being curved on its upper face to fit the header and having a downwardly inclined side extension which is grooved to support a tube 32 or 33. The furnace is fired by a pulverizedfuel burner 16 surrounded by an air-box 21 having ports 22, there being also provided a pipe 22 for the supply of gas under pressure to start or sustain the combustion of the powdered fuel. The upper part of the furnace is constituted by brickwork 53 which carries pins 55 loosely connected to the steel framework adjacent the upper headers and is supported on a row of castings 52 surmounting metal blocks which form the inner face of the walls. The brickwork 53 is' spaced below the boiler tubes 17 to allow expansion of the header 18, the space between the latter and the wall being sealed by a plate 56.

Abstract: 1,059,452. Packaging-machines. R. A. JULY. April 1, 1965 [April 2, 1964], No. 13830/65. Heading B8C. A machine for completing the folding-down and sealing of tubular carton end closure flaps, the cartons being fed in horizontally with trailing and upper flaps at opposite ends already folded down, has means to fold in the leading flaps and apply glue to the lower flaps. These are then folded on to the carton ends during its downward passage on a vertically reciprocating platform, the passage of the cartons on the platform and operating of the gluing means being controlled by a switch operated by an incoming carton. Cartons are fed in between guides 7 which fold in the leading flaps, and abut a stop 11. The leading carton is then supported on a platform 6 carried by a rod 8. It engages a switch arm 20 causing glue-applying members (13), Fig. 3 (not shown), to be swung inwards by parallel linkage 15 connecting them to the platform operating linkage as the platform commences to descend. Fixed folders adjacent the carton ends lay down the glued flaps which are pressed by opposed rollers 30 in the discharge channel as a horizontally reciprocating pusher 12 forces the carton off the platform at its lowest position. The stroke of the pusher, the platform travel and the stop 11 are adjustable for various carton sizes.

Title: An improved process for the preparation and reactivation of metallic catalysts used in the hydrogenation of oils and like substances
IPC: B01J23/70
Filed: 1923-05-31
Abstract: Catalytic metallic surfaces, particularly of the nickel employed in the hydrogenation of oils, &c., are activated and re-activated by oxidation with hypochlorous acid or its salts, followed by reduction in hydrogen.  The catalytic metal, after the removal if necessary of contaminating oil &c., is immersed in a solution of hypochlorous acid or in an alkaline solution of bleaching powder or hypochlorite. After washing with water, the mass is reduced with hydrogen at a temperature of 250-350 DEG  C. The process may take place in situ, in which case the hydrogenation vessel is made of nickel, copper, or glass or is lined with nickel, copper, or enamel.  The catalytic metal, which may be in the form of turnings or powder or be deposited on a carrier such as kieselguhr, may be placed in a container which fits into the hydrogenation vessel.  Specification 203,218 is referred to.

Abstract: 791,486. Colour television tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 9, 1956 [May 12, 1955], No. 14415/56. Class 39(1). A cathode ray tube for the reproduction of coloured television images having a picture screen comprising at least two luminescent materials which emit light of different colours with different efficiency and are arranged in discrete uniformly distributed surfaces, and at least two electron guns producing electron beams which each pass through a principal lens having the same image ratio and each cooperating with luminescent material only which emits light of one colour, whilst to the control electrode of a gun co-operating with a luminescent material of higher efficiency a signal is supplied having a larger bandwidth than the signal supplied to the control electrode of a gun co-operating with luminescent material of lower efficiency is characterized in that the spot of a gun co-operating with luminescent material of higher efficiency, at a given current strength and with maximum focusing by the principal lens, is smaller than that produced by a gun which co-operates with luminescent material of lower efficiency, at the same current strength and maximum focusing. By this means equal intensity of illumination in the two colours is achieved by greater beam current strength over greater control electrode apertures so that the specific current loading of the the gun cathodes can approximate to the same value. Variation in control electrode aperture size from gun to gun would normally mean that each gun has a different cut-off voltage but by varying the cathode-control electrode distance this complication may be avoided. Preferably the principal lens is common to all the guns and the distances by which the cathodes are spaced away from the principal lens are all equal. Specific numerical examples are given.

Title: Improvements in or relating to block printing-machines for printing on floor coverings or the like
IPC: B41F1/10
Filed: 1929-05-08
Abstract: 312,065. Armstrong Cork Co., (Assignees of Webster, H. A.). May 18,1928, [Convention date]. Platen machines.-A block printing-machine for printing patterns of various designs on linoleum, &c., is constructed with means for positively effecting relative movement between individual printing-blocks 10 carried on a single crosshead of a machine such as that described in Specification 304,237, which comprises several heads 7, and cam-actuated parts 6 for operating the same in the desired order. As in the prior Specification, each block 10 is mounted on four rods 11 normally raised out of printing position by springs 15, and depressed as required into printing position by cams 20<a>, 20b, 21a, acting on adjustable followers 13 and mounted in open bearings so as to allow of different cams to be readily inserted. These cams are intermittently rotated to move the blocks 10 into and out of action, and the extent to which the cams are rotated is variable, and this variation produces the required design. Each cam shaft is geared to an intermittently rotated shaft 25, which is rotated only on the upward motion of the head 7, by means of a spring-pressed hook 51 operated by a freely mounted lever 35 connected by an adjustable eccentric pin to a link 37 pivoted to the bed of the machine. The hook 51 is pivoted to the pivot pin 47 of a link 48, and a link 46 pivoted to the lever 35. The hook 51 normally engages a pin 27 on a disc 26 fixed to shaft 25, but as the head 7 descends an upper pin acts on the inclined upper part of the hook and movement free of the lower pin. As the head 7 rises, the hook engages a pin 27 and rotates the disc 26 to an extent equal to the distance between two successive pins 27. By omitting some of the pins 27 the disc 26 can be rotated to a greater extent, and the cam-shafts are thus also rotated to a greater extent. The prints obtained from each block 10 are thus controlled by omitting certain of the pins 27, and by varying the form of the cams 20<a>, 21<a>.

Title: Improvements in the manufacture of carbon black
IPC: C09C1/50
Filed: 1950-06-09
Abstract: <PICT:0670863/III/1> <PICT:0670863/III/2> A carbon black production process comprises heating a confined stream of gaseous hydrocarbon, substantially free from hydrocarbons containing more than 2 to 3 carbon atoms per molecule, to a temperature and for a period of time such as to effect partial pyrolysis to an extent just short of the point where any substantial amount of carbon is liberated, injecting the partially pyrolyzed gas immediately thereafter into a turbulent stream of furnace gases at a temperature in excess of that at which the hydrocarbon gas is decomposed to form carbon black, cooling the gaseous suspension of black and separating the black. Fuel gas under pressure is injected through manifold 24 and headers 23 to nozzles 21, Fig. 3, while air under pressure passes through perforated plate 31 to windbox 19.  The resulting combustible mixture burns in ports 16 in refractory burner block 15 and the blast flame gases pass from the burner assembly 2, Fig. 2, into refractory lined chamber 1. Natural gas containing at least 95 per cent methane is injected, with or without steam, through manifold 26 and headers 25 to refractory tubes 17 which terminate at least 18 inches from the face of the burner block. The gaseous suspension of carbon black passes through blending chamber 3, and passage 4, having water sprays 11, to precooler 5. The position of tubes 15 and nozzles 21 may be adjusted by sliding manifolds 26, 24 respectively in and out.  Tubes 17 may contain a known reforming catalyst.  Specifications 652,518 and 670,864 are referred to.
