Filed: 1926-08-04
Abstract: 261,665. Kronenberk, R. Aug. 4, 1926. Rolling.-To prevent metal bands from being rolled out in a curve, the upper roll d can be tilted during working in relation to the axis of the lower roll e by mounting the bearings f of the roll d in a convex cross piece i fitting into a hollowed head piece k each provided with an arm u and t so that by screwing the spindle wheel y the crosspiece i moves in the hollow of the head piece k and so oscillates the roll d, such tilting being independent of the height adjustment. The roll d is adjusted up or down by the capstan wheel s through gearing and screwed spindles m and n; for fine adjustment micrometer divisions may he placed on the capstan wheel. The tilting of one roll may also be attained by two hand operated eccentrics working in opposite directions, or by two toggle links, or the cross and head pieces may be rocked by a hand screw about a large pin as centre. The cross and head pieces may have roller or ball bearings interposed between their moving surfaces, and they may be hollowed for cooling liquid.

IPC: C09C1/50
Filed: 1961-05-31
Abstract: <PICT:0946805/C1/1> <PICT:0946805/C1/2> Apparatus for producing carbon black comprises an elongated metallic housing 10 (Fig. 1) in which there is concentrically disposed a metallic tube 11, having an inner lining of refractory 12, said tube 11 being of lesser diameter than housing 10 and terminating short thereof at the upstream end to form a cylindrical chamber 13.  The housing is closed at the upstream end by closure 21 through which passes gaseous fuel and hydrocarbon injection means 23, concentrically disposed in chamber 13.  Air supply means 14 are situated near the downstream end of the apparatus, said air supply means being adapted to impel air towards the upstream end of the apparatus through the annular space between housing 10 and tube 11.  Towards the upstream end of tube 11 are positioned air deflection means to impart inwardly spiralling motion to the air flowing from the annular space.  Said air deflection means may comprise a plurality of spaced helicoidal strips 15 disposed between the outer surface of tube 11 and the inner surface of housing 10, or a flared extension 17, e.g. a metallic frusto-cone, communicating with tube 11 at the upstream end thereof and provided with a series of peripherally extending louvers 19, or a combination of the two as shown in Fig. 1.  There may also be provided a plurality of ports 18 providing communication between the annular spacing and the inside of tube 11, said ports being positioned so as to direct air passing therethrough in a direction substantially tangent to the inner surface of the reactor. The gaseous fuel and hydrocarbon injection means 23 are described in detail with relation to Fig. 2 (not shown) in the Specification.  Fig. 6 illustrates a modification of the apparatus incorporating a novel quench section which is provided by a downstream extension of tube 11 and housing 10 beyond quench ports 36, the air inlet ports 14 now being downstream of the quench section.  Fins 37 are attached to the outside of tube 11, starting at the point where the refractory lining 12 ends, so that heat from the gases being quenched is transferred via the fins to the air passing through the annular space via helically disposed vanes 38, so as to result in preheating of the air. Members 42 may also be provided as indicated to facilitate the incidence of the helically progressing air on to the fins 37.  Fig. 7 (not shown) illustrates a further embodiment in which the quench section and reactor section of the apparatus do not share common tubular members for their outer shells and inner tubes.  Specification 893,378 is referred to.

Title: Colour Detection using a Chromic Absorption Filter

Filed: 1967-04-28
Abstract: 1,189,202. Colour television. BELL & HOWELL CO. 28 April, 1967, No. 19785/67. Heading H4F. [Also in Division G2] Light from an object is passed along two different paths, in one of which is disposed a colour filter, in the other no filter, or a neutral filter, the two images being formed in black and white. By comparing the optical densities of corresponding parts of the two images, the original colouring of the object may be reconstructed. Fig. 1 shows light from an object 10 passing through a lens system 11 to a beamsplitter 12. Part of the light then passes along path 14, through a neutral filter 16 having an optical density of 0À5 to all visible wavelengths, to be recorded as a black and white image on film 18. The other part of the light passes along path 20 through a variable density filter 21 to be recorded as a black and white image on film 24. If filter 21 is most transmissive to blue, and least to red, then a blue portion of object 10 will show up as denser on film 24 than on film 18. A red portion will show up as less dense, and a green portion as about the same. The films 18 and 24 may be replaced by black and white television cameras 42 and 44, Fig. 3. The signals from the two cameras are fed to a comparer 34, the difference between them developing a chromatic electrical signal which, together with a light intensity signal from the first camera, is fed to a television colour circuit which presents a colour picture of the original object on a colour television tube 38.

The end of the waveguide (1) remote from the generator is cut off at an acute angle (Fig. 1, not shown), and the opening closed by a plate 4. A radiation screen (10) may be fixed to plate (4), and the plate (4) may carry microswitches (11) in the control circuit of the generator such that microwave energy is beamed at the structure to be cracked only when the plate (4) is held close to the structure (Fig. 5, not shown).

[Classes 83 (ii) and 83 (iii).] The apparatus described in the parent Specification is modified by the provision of means whereby the radial displacements of the tool holder 2 rotating about the axis of the arbor 8 may be effected during any desired part of the angular movement. For this purpose the cams 18 controlling the radial movement are carried on a holder 19 which is rotatable about the arbor axis and is connected by a link 15 to an adjustable crank disc 80. The cams 18 in the normal position, corresponding to the fixed position of the parent Specification, are connected to the crank disc, as shown in Fig. 3, and the crank disc is rotated at twice the speed of the tool holder. The rollers 16 will then be in contact with the cams between the position shown in Figs. 5 and 7, and a roll profile having a straight side portion subtending an angle alpha<1>, is produced. By arranging the connection between the cam holder and the crank disc in the manner shown in Fig. 10, a roll profile having a straight side portion subtending an angle alpha<2> may be similarly produced. For cutting a roll profile similar to that described in the parent Specification, the link is connected to the centre of the crank disc 80. The crank disc is adjustable by a screw 82 and is driven from the shaft of the pinion 7, Fig. 11, through chain gearing 77 at twice the speed of the arbor 8. The cam holder 19 also carries the ring member 17 on which the rollers 16 move when out of contact with the cams 18. Vertical movements are imparted to the cams 18 through worm gearing 32.
